CCTV News:On January 13th, 2017, a press conference was held in the press room of the State Council Information Office. When introducing the import and export situation in 2016, Huang Songping, spokesman of the General Administration of Customs, said that in 2016, the world economy recovered difficultly and the domestic economy improved steadily.

　　He reported on China’s foreign trade import and export in 2016. In 2016, the world economy recovered difficultly, and the domestic economy improved steadily. According to customs statistics, in 2016, the total import and export value of goods in China was 24.33 trillion yuan, down 0.9% from 2015. Among them, exports were 13.84 trillion yuan, down 2%; Imports reached 10.49 trillion yuan, up by 0.6%; The trade surplus was 3.35 trillion yuan, narrowing by 9.1%.

　　The specific situation mainly includes the following aspects:　

　　I. Imports and exports stabilized quarter by quarter, and both achieved positive growth in the fourth quarter. In 2016, China’s import and export showed a trend of low before and high after, and stabilized and improved quarter by quarter. Among them, in the first quarter, China’s import and export, export and import value decreased by 8.2%, 7.9% and 8.6% respectively; In the second quarter, the value of import and export, export and import decreased by 1.1%, 0.8% and 1.5% respectively; In the third quarter, the import and export value increased by 0.8% and 2.3% respectively, while the export value decreased by 0.3%; In the fourth quarter, the value of import and export, export and import increased by 3.8%, 0.3% and 8.7% respectively.

　　Second, the import and export of general trade increased and its proportion increased. In 2016, China’s general trade import and export was 13.39 trillion yuan, up 0.9%, accounting for 55% of China’s total import and export value, up 1 percentage point from 2015, and the trade pattern structure was optimized.　

　　Third, export growth to some countries along the Belt and Road. In 2016, China’s exports to Pakistan, Russia, Poland, Bangladesh and India increased by 11%, 14.1%, 11.8%, 9% and 6.5% respectively. In the same period, China’s exports to the EU increased by 1.2%, to the United States increased slightly by 0.1%, and to ASEAN decreased by 2%, accounting for 46.7% of China’s total exports.　

　　Fourth, the proportion of private enterprises’ exports continued to maintain the first place.

Among them, exports were 6.35 trillion yuan, down 0.2%, accounting for 45.9% of the total export value, and continued to maintain the top position in export share; Imports increased by 8.1%.

　　Five, mechanical and electrical products, traditional labor-intensive products are still the main export. In 2016, the export of mechanical and electrical products in China was 7.98 trillion yuan, down by 1.9%, accounting for 57.7% of China’s total export value. Among them, the export of medical instruments and instruments increased by 6.1%, and the export of storage batteries increased by 4%.

　　CCTV News:Today is "national love teeth day". According to the results of the third national oral epidemiological survey, more than 85% of adults in China suffer from periodontal diseases, which are closely related to the health of other organs in the whole body.

　　Periodontal diseases are related to organ health.

　　Periodontal diseases mainly include gingivitis and periodontitis. It is a common oral disease that gingiva and tissues around teeth are inflamed and destroyed under the action of dental plaque, which leads to tooth loosening and falling off.

　　The oral cavity is the entrance of respiratory tract and digestive tract. Periodontal diseases not only harm the oral cavity, but also are closely related to the whole health. When periodontal diseases occur, a large number of bacteria gather on the tooth surface and periodontal area, forming erosive ulcer surface. When a large number of bacteria accumulate on the ulcerated surface, daily chewing activities can make bacteria and toxic products enter the blood circulation, increasing the risk of systemic diseases.

　　Luan Qingxian, director of the Department of Periodontology at Peking University Stomatological Hospital, pointed out that periodontal diseases are linked to the heart, the brain, the lungs, the stomach and the next generation. For example, research now believes that if there are inflammatory factors in the blood, it will increase the prevalence of diabetes. Other studies have shown that the prevalence of cardiovascular and cerebrovascular diseases in patients with periodontal diseases will also increase.

　　Prevention of periodontal diseases and avoidance of obsolescence

　　The tooth loss rate of the elderly aged 65 to 74 in China is as high as 86%, while 10% of the elderly have no teeth at all. Experts remind that missing teeth will add a lot of burden to the digestive system and cannot be underestimated.

　　Tooth loosening is a slow process of physiological change, and the most effective way to avoid tooth loss is to prevent periodontal disease. Symptoms of periodontal disease include gingival bleeding, gingival swelling, pain, etc., which can cause teeth to loosen or even fall off in severe cases. Plaque and tartar are the chief culprit of periodontal disease, and adults should wash their teeth once a year.

　　Some people say that it is a natural law for people to lose their teeth when they are old, and there is no need to repair them. The doctor reminded that if the teeth are missing, the balance of the whole mouth will be disturbed. If not repaired in time, the rest of the teeth will be tilted, displaced and periodontal damage will be caused.

　　Children and pregnant women should pay special attention to oral health.

　　Special attention should be paid to the oral health of children and pregnant women. Children’s oral examination should start within 6 months after the first deciduous tooth erupts, once every six months. The oral health of pregnant women is not only related to their own health, but also affects the health of the fetus, which may lead to premature delivery and low birth weight infants. Moreover, during pregnancy, due to factors such as hormonal changes in the body and decreased immunity, pregnant women are particularly prone to cause dental and gingival lesions.

　　Small floss is a good helper for tooth cleaning.

　　A large number of studies have confirmed that although periodontal disease is the most prevalent oral disease, it can be prevented and cured. In addition to brushing our teeth on weekdays, there is also a small tool that can help us clean the plaque between our teeth, and that is dental floss.

　　The doctor said that brushing teeth with a toothbrush can only clean 70% of teeth, and the other 30% is the gap between teeth. Many oral diseases are caused by the uncleanness of the gap between teeth. Flossing can effectively remove residual food, soft tartar and clean dental plaque.

　　How to use dental floss stick correctly?

　　For patients who floss for the first time, a dental floss stick is a good choice. When you use the dental floss stick, the dental floss is directed at the gap between teeth, and gently slides the gap between teeth by horizontal pulling and oblique pulling, so that the dental floss is "C"-shaped, and then it is pulled up and down for four to six times, and then the other side, which is also the "C"-shaped, is cleaned, and then it is pulled up and down for four to six times, and finally the dental floss is slowly pulled out from the gap.

　　Experts emphasize that dental floss cannot be reused. Some friends reuse the same dental floss for convenience, which is very undesirable. Because dental floss will carry a lot of germs after cleaning teeth, and these germs can’t be washed clean with water. Frequent use may bring more bacteria to teeth, so be sure to pay attention!

　　There is no harm in using dental floss. As long as you master the correct use method, don’t use too much force to avoid damaging your gums, you can floss once or twice a day.

　　Can you really brush your teeth?

The renovation of old residential areas is a major livelihood project and development project. General Secretary of the Supreme Leader pointed out that the renovation of old residential areas is an important task to enhance people’s sense of gain, and it is also an important part of the implementation of urban renewal. The Community Construction Department of the Urban Construction Department of the Ministry of Housing and Urban-Rural Development (hereinafter referred to as the "Community Department") takes the transformation of old residential areas as the focus of doing practical things for the masses, and solves the "great livelihood" with "small incision" to continuously enhance the people’s sense of acquisition, happiness and security.

This year, this young team won the National Worker Pioneer. "The renovation of old residential areas is an important task to improve people’s quality of life, and it is a practical matter of people’s livelihood around the people. We are honored to be able to shoulder the heavy responsibility and win the honor, and we feel even more responsible. " Relevant comrades in the community office said.

Find out the base, pilot first, and clarify the direction of the transformation path

Most of the old residential areas were built before 2000. The construction standards of these residential areas are low, coupled with long-term neglect, incomplete municipal supporting facilities, aging houses and other outstanding problems. There are shortcomings in facilities, environmental supporting facilities and public services, which is far from the growing needs of the people for a better life. Residents have a strong willingness to transform. Old residential areas are large in quantity and wide in scope, and the task of renovation is heavy. How to promote renovation in a solid and orderly manner throughout the country?

Understanding what the masses think and expect, and learning from the grassroots is the first priority. The Community Department organized 20 departments and units to conduct in-depth research on 213 old communities in 93 cities and counties, and combed and analyzed the current situation, transformation needs and experience of old communities. Subsequently, Shandong and Zhejiang provinces and eight cities including Shanghai and Suzhou were organized to deepen the pilot projects, and special classes for joint work were set up with local comrades to jointly explore the establishment of nine mechanisms, such as mobilizing the masses to jointly build, sharing reconstruction funds and integrating and utilizing existing resources, and to "explore the road" in the reconstruction projects in detail, so as to accumulate experience for comprehensively promoting the transformation.

On the basis of comprehensive investigation and summing up the pilot experience, the Community Department took the lead in drafting the Guiding Opinions on Comprehensively Promoting the Renovation of Old Urban Residential Areas, which defined the target tasks and the scope of objects, established a package of support policies to meet the needs of renovation projects in terms of approval of renovation projects, taxation and finance, land and so on, basically formed the institutional framework for the renovation of old urban residential areas, and the renovation work was rapidly and comprehensively promoted throughout the country.

Guide the whole process and do a good job in deployment and implementation.

Since 2019, the country has started to renovate nearly 220,000 old urban communities, benefiting hundreds of millions of people. However, the larger new start-up tasks every year, coupled with the projects under construction, have brought great pressure to the streets and communities at the grassroots level. How to make the policy better adapt to the needs of the grassroots and land solidly?

The community department insists on keeping its eyes down, stepping down, throwing itself down and sinking into the front line, so that the policy can be passed on layer by layer from formulation to promotion to landing.

"The transformation of old residential areas is the initial intention and mission of this office. We are both policy makers and policy practitioners and implementers." Relevant comrades said.

According to reports, since 2019, the renovation of old residential areas has been included in the affordable housing project, and the General Office of the State Council has issued guidance. The Ministry of Housing and Urban-Rural Development, together with relevant departments, put forward targeted work requirements for the renovation work in that year according to the latest situation, tasks and objectives, and new situations and problems arising in the renovation, and made clear the "positive list" and "negative list" of work, so as to promote all localities to do their best and do their best to promote the renovation well and quickly.

With the gradual advancement of the renovation of old residential areas, the Community Department promptly answered questions about the difficulties encountered in various localities, followed up and summarized the deepening innovations in the implementation of policies in various localities, organized and printed seven batches of List of Replicable Policy Mechanisms for the Renovation of Old Urban Residential Areas, promoted the replicable experiences and practices in pioneering areas, guided all localities to learn from them, accelerated the improvement of working mechanisms and policy systems that meet the needs of renovation, and promoted the implementation of renovation policies.

For example, in order to solve the problem of "public needs and women need to face" in the transformation of old residential areas, the community department guides all localities to fully mobilize the masses to participate, ask for the needs of the people, ask for the people, ask for the benefits of the people, and seek the greatest common denominator of the transformation effect.

In the residents’ meeting hall of an old residential area in Qingdao, Shandong Province, a young cadre from the community office discussed the renovation plan of the residential area with the residents. Because there are many people in the surrounding primary schools during school hours, the residents are very concerned about the design plan of optimizing the internal traffic routes and getting through the fire exits. "Making policies and implementing them are different. Every old residential area has its own characteristics, and the needs of each resident are different. The renovation plan must be determined according to the wishes of residents and the actual situation of the residential area. In this process, it is very important to be with residents, want to be together, and be together. " The young cadre said with emotion.

Experience comes from grassroots practice and wisdom. The community department adheres to the typical demonstration and leads the way, and promotes the transformation process in various places with demonstration projects. Since 2021, the Community Department has identified a number of contact points communities every year, and adopted the methods of leaders’ efforts, young cadres’ on-the-spot investigation, and experts’ assistance to help the communities break the blocking points of renovation, create demonstration model projects, and share experiences and experiences with community cadres in the streets where various renovation communities are located throughout the country.

In order to evaluate the transformation work more scientifically and objectively, the community office has defined the measurement standard of the transformation work through performance evaluation, supervision and encouragement, so as to make the policy baton and the evaluation index system more unified. During the research and establishment of the National Statistical Investigation System for the Renovation of Old Urban Residential Areas, the Community Department, together with grassroots comrades, repeatedly studied the connotation of each statistical indicator in order to be accurate and efficient, focusing on the goal of timely and accurately reflecting the progress of the renovation and minimizing the statistical burden. "This set of statistical indicators has clear logic and strong pertinence, which is very helpful for guiding and promoting local work. The progress of the work can be clearly reflected in the statistics. Behind the figures are the transformation results that every resident can see and touch, and they are all tangible results. " A grassroots cadre responsible for the renovation of old communities said.

The central and local governments have resonated at the same frequency and exerted their strength in the same direction, overcoming difficulties and taking advantage of the situation. The policy implementation has not only not weakened, but the signal has become stronger and stronger.

Cooperate to fill the shortcomings and improve the supporting facilities

Living and working in peace and contentment is the simplest wish of China people. Residents spend most of their daily life, food, clothing, housing and transportation in the community. In order to do the "last mile" of serving the masses well, the Community Department cooperated with various departments Qi Xin to integrate resources and fill the shortcomings of facilities and services.

"what is missing, what to make up." The Community Office guides all localities to explore the working method of "physical examination before renovation", and before renovation, it conducts a thorough investigation of the facilities in the community, focuses on residents’ needs, adheres to goal orientation and problem orientation, adopts "menu-based" renovation, and makes precise efforts with "one district, one policy", giving priority to solving the urgent problems of the masses, using limited funds at the cutting edge and changing them into residents’ "hearts".

"Stick to the bottom line of safety" and focus on eliminating potential safety hazards. Accelerate the renovation of aging and hidden dangers of gas, water supply, heating, drainage, power supply, communications and other pipelines and pipelines, and put the concept of safe development throughout all links and the whole process of renovation.

"One old and one young" is the main concern of most families. The Community Department guides all localities to actively revitalize the housing and land resources in the community and surrounding areas, and add service facilities such as home care service centers, canteens for the elderly and children’s post stations according to local conditions. In conjunction with the State Sports General Administration, the "national ball into the community" campaign was launched, and small sports and fitness facilities such as table tennis tables were added for old communities to allow residents to move at their doorsteps.

In recent years, residents have a high voice for installing elevators in existing houses, and the community department has faced up to the difficulties of reaching a consensus and raising funds, and adhered to the combination of rule of law and rule of virtue to help solve the problem of "it is difficult for suspended elderly people to go downstairs". Seize the favorable opportunity when the National People’s Congress promulgated the law on barrier-free environment construction, and promote national legislation to support the installation of elevators in existing multi-storey houses in old urban communities. Give play to the role of grassroots organizations in street communities, take party building as the guide and residents’ consultation as the basic working methods, and promote residents to reach a consensus. In conjunction with the Supreme People’s Court, a typical case was issued to guide residents to correctly understand the legal provisions applicable to installing elevators, and to carry forward the traditional virtues of the Chinese nation, such as being good neighbors and helping each other.

Great cause inspires people to forge ahead. The achievements made by the Community Office courageously come from the broad masses of the people’s support for the major decision-making arrangements of the CPC Central Committee and the State Council, and also reflect the hope of millions of grassroots community workers and community residents to work together to build a beautiful home.

　　[XCAR Five Questions and Five Answers Original]

　　On August 22, 2016, the new E-class long-axis version of Beijing Benz was officially launched, and a total of six models were launched, with a price range of 436,800-499,800 yuan. The Mercedes-Benz E-Class long-axis version listed this time is the tenth generation model and the third generation model made in China. The new Mercedes-Benz E-class long-axis version continues the essence of S-class in appearance and interior. Compared with the standard-axis version, the wheelbase has increased by 140mm, and the configuration has been improved in all directions. The competitiveness is no longer the same as that of the old model. What are the highlights of the new Mercedes-Benz E-Class Long Axis Edition? Can face value and configuration conquer consumers? Is the comprehensive competitiveness strong? The following is to answer these questions through the special column "Five Questions and Five Answers" of Aika Automobile. Let’s talk about the editor’s personal thoughts in advance. When I see the brand-new Mercedes-Benz E-Class long-axis version, I want to buy one especially even if I borrow money. I wonder if you will have this idea after reading the following introduction!

　　Question 1: Which generation is the new Mercedes-Benz E-Class long-axis version?

　　In fact, friends who are interested in Mercedes-Benz E-Class must have a better understanding of its history, but I believe there are still many netizens who are not very clear about it, or only know about several generations of models that are closer to us. In fact, the development of Mercedes-Benz E-Class has experienced ten generations of models. For a model with a history of nearly 70 years, we have no reason not to understand its past. In other words, the first generation of Mercedes-Benz E-Class has been very far away from me. At that time, my parents were not born yet, so I couldn’t learn about the past of Mercedes-Benz E-Class from my parents, so I could only collect materials from all directions. If there is any poor introduction, please forgive me.

　　The first generation models are for you who like nostalgia.

　　Need to remind everyone that before the launch of the mid-term redesign of the sixth-generation Mercedes-Benz E-Class, it was not named after the familiar "E-Class", but named after the chassis number of W plus number.

　　　 Let’s first look at what the first generation of Mercedes-Benz E-Class looks like. The birth of the first generation of Mercedes-Benz E-Class dates back to 1947. After World War II, Mercedes-Benz resumed production of 170V and 170S models with chassis codes W136 and W191. The first generation of Mercedes-Benz E-Class was improved according to the model before World War II. The features such as independent headlights and independent rims are very obvious and full of retro style.

　　The second generation Mercedes-Benz E, the first sedan captain, is like this.

　　In 1953, the second generation Mercedes-Benz E-Class was born. The model was named 180 and the chassis number was W120. The second-generation Mercedes-Benz E-Class has completely escaped from the shadow of the first-generation model, and it is also the first sedan of Mercedes-Benz E. It adopts a non-loaded body to ensure spacious interior space. In terms of power, it adopts a 1.8L four-cylinder engine with a maximum power of 52Ps, and the transmission is matched with a 4-speed manual transmission. In 1955, the second generation Mercedes-Benz E introduced an upgraded model 190 with chassis code W121, which was not discontinued until 1961.

　　The sales volume of the fin-shaped tail of the third-generation model exceeded 620,000.

　　In 1961, Mercedes-Benz introduced the third generation E-Class with chassis code W110, including two models: 190c/190Dc. The biggest change of this generation is the fin-shaped rear design. The body size has also been upgraded, with a length of 4730mm and a wheelbase of 2700mm.

　　　 In terms of power, the 190c is still equipped with a 1.9L gasoline engine with a maximum power of 80Ps, while the 190Dc is equipped with a brand-new 2.0L diesel engine with a maximum power of 55Ps. Since 1962, W110 series has added a four-speed semi-automatic gearbox on the basis of a four-speed manual gearbox. In addition, in the later period of W110 series, a 230 model equipped with a six-cylinder 2.3L gasoline engine was added for the first time, with a maximum power of 105Ps. By the end of production in 1968, the third-generation Mercedes-Benz E-Class sold a total of 620,000 vehicles.

　　The fourth-generation models have sold more than one million years ago.

　　In January 1968, Mercedes-Benz officially launched the brand-new Stroke Eight "/8" car series, which is the fourth generation Mercedes-Benz E, with the chassis code W114/W115. This generation of cars has changed greatly in appearance, giving up the fin-shaped rear design of the third generation models and using a lot of concise and lively design styles. In addition, this generation of Mercedes-Benz E-Class models began to enrich, providing a total of 15 models for consumers to choose from, which is also a huge vehicle layout today.

　　In addition, it should be noted that the parking brake of the fourth-generation Mercedes-Benz E bid farewell to manual operation, but adopted the pedal-operated auxiliary brake that we are very familiar with, and at the same time adopted the diagonal swing shaft on the rear suspension, which improved the overall balance, comfort and stability of the vehicle. In terms of power, the W114 series is equipped with a six-cylinder engine, and the upgraded W115 is equipped with a five-cylinder or four-cylinder engine. The top 250CE model also joined the Bosch D-Jetronic electronic fuel injection system for the first time. The fourth-generation Mercedes-Benz E-Class didn’t stop production until 1976, and the cumulative sales volume was close to 2 million.

　　The fifth-generation car was made in China for a short time but left an eternal memory.

　　In 1976, Mercedes-Benz officially launched the fifth-generation Mercedes-Benz E-Class with chassis code W123. This generation of cars has undergone minor changes in appearance, such as changing the lights to horizontal design, and the shape of the water tank grille at the lower part of the front face is also very modern. This generation of Mercedes-Benz E launched the five-door travel version, two-door Coupe version and four-door long-axis version for the first time.

　　In terms of safety, the fifth-generation car has also made a qualitative leap. First, the fuel tank is placed on the rear axle of the car to reduce the danger caused by collision. In addition, a new safety steering column is added, which can fall off sideways in a side collision to prevent the steering wheel from folding into the car in an accident and causing harm to the people inside the car. In the mid-term change, this generation of E-class supports the optional ABS and driver airbag, and the safety is further improved. In terms of power, this generation of Mercedes-Benz E-Class adopts a new 2.8L inline 6-cylinder DOHC fuel injection engine on the 280E model, with a maximum power of 142Ps.

　　It should be noted that in 1988, the fifth-generation E-Class was also introduced from Changchun FAW in the form of CKD, with a total volume of 828. Less than 1,000 of these vehicles are mainly used by senior national leading cadres and foreign guests, and the number of them entering private homes is very small, which cannot be compared with today’s domestic E-class.

　　The sixth-generation car was officially named "E-Class Car" and was first imported into China.

　　In 1985, Mercedes-Benz introduced the sixth generation of Mercedes-Benz E-Class, and the chassis code was W124. In June 1993, the name of "E-Class sedan" in E+ digital mode was formally determined. This generation of E-Class sedan was also the first E-Class imported from China by Mercedes-Benz.

　　The sixth-generation E-class has changed greatly in appearance, and the overall design is more elegant and stable, and the convertible version has been launched for the first time. The weight of this generation of cars has been optimized, the handling performance is better, and the aerodynamic design is equally excellent. The drag coefficient of 0.28 is the best evidence. In terms of safety, the driver’s airbag and ABS have been changed from the option of the previous generation to the standard, and new options such as the co-pilot airbag and ASR traction control system have been added.

　　In terms of power and chassis, in addition to retaining the four-cylinder, five-cylinder and six-cylinder engines, this generation of models has also introduced a 500 E model equipped with a 5.0L V8 engine, with an acceleration time of 6.1 seconds from 0 to 100 km/h and a maximum speed of 250km/h, making it the first model equipped with the first generation of 4MATIC four-wheel drive system. In terms of chassis, this generation of models adopts front multi-link and rear independent suspension, which is more excellent in comfort and handling. In addition, in 1986, the two-door Coupe was also equipped with a 5.6L V8 engine with a completely independent cylinder head developed by AMG, which was only an engine manufacturer at that time. The maximum power reached 360Ps and the 0-100km/h acceleration time was 5.4 seconds. Then in 1990, Mercedes-Benz officially cooperated with AMG, and the launch of E 60 AMG and E 36 AMG created the history of E-class AMG models.

Recently, the Hunan Provincial Health and Health Commission and the Hunan Provincial Department of Education issued the Notice on Strengthening the Prevention and Control of Key Infectious Diseases in Schools in Autumn and Winter. Infectious diseases on campus mainly spread through respiratory tract in autumn and winter, and some spread through digestive tract and contact, so it is easy to break out and spread in campus, so we should pay special attention to prevent the spread of infectious diseases.

According to the epidemic situation and incidence characteristics of infectious diseases, the school hospital has sorted out several knowledge of prevention and treatment of common infectious diseases in autumn and winter, please pay attention to it!

I. Influenza

(A) disease science

Influenza is an acute respiratory infection caused by influenza virus, and it is also a highly contagious and fast-spreading disease. Fog droplets ejected mainly by coughing or sneezing of infected people are transmitted to others through the air, and can also be infected by touching objects contaminated by influenza virus. The main clinical manifestations are high fever, headache, limb aches, fatigue and upper respiratory symptoms such as runny nose and cough. The infirm and the elderly are prone to pneumonia and other complications after infection.

The difference between influenza and common cold

(2) Prevention and control suggestions

1. Before the flu season, it is an effective way to prevent the flu by vaccinating high-risk groups and susceptible groups.

2. Reasonable arrangement of work and rest time: have a regular life, ensure adequate sleep, and avoid the decline of resistance caused by overwork, thus increasing the chance of illness.

3. Pay attention to personal hygiene: don’t spit everywhere, and cover your mouth and nose with a handkerchief or paper towel when sneezing or coughing.

Wash your hands frequently, and wash your hands immediately after touching respiratory secretions (such as after sneezing).

4. Open the window and ventilate several times a day to keep the indoor air fresh. During the high incidence of influenza, try not to go to crowded places with dirty air; You’d better wear a mask when you have to.

5. Effective prevention approaches: early detection, early reporting, early isolation and early treatment. Isolating patients is the most effective way to reduce transmission.

Second, cold diarrhea

(A) disease science

Infectious diarrhea refers to diarrhea caused by intestinal infection of pathogens such as bacteria, viruses, parasites or fungi. Its prevalence is wide, the incidence rate is high, it has the characteristics of acute onset, rapid spread and wide coverage, and it is an important disease that harms health. Mostly due to the intake of unclean diet (such as cold dishes, spoiled shrimp, crabs, drinks, etc.) and water, due to bacterial and viral pollution, coupled with some people’s bad hygienic eating habits, the disease enters the mouth. The clinical manifestation is diarrhea, which may be accompanied by abdominal pain, fever, nausea, vomiting and other symptoms. The stool characteristics often vary with different pathogens, and in severe cases, fever, dehydration, electrolyte disorder, abnormal renal function, acidosis, shock and so on may occur. Infectious diarrhea pathogens are excreted with excreta, which pollutes the environment, food and water sources and can cause outbreaks.

(2) Prevention and control suggestions

1. Pay attention to drinking water hygiene, don’t drink raw water, don’t eat cold and spoiled food, especially seafood and aquatic products.

2. Pay attention to food hygiene, don’t overeat, and eat less food that is easy to carry germs and be bitten by flies; Tableware should be disinfected, and raw and cooked tableware should be separated; Try to eat cooked food, and wash and peel raw fruits and vegetables.

3. Pay attention to personal hygiene, wash your hands before and after meals, do not defecate anywhere, do not dump garbage and dirt, and do not pollute water sources.

4. Report the patients with vomiting and diarrhea in time, and see a doctor as soon as possible for timely diagnosis and treatment.

Third, tuberculosis

(A) disease science

Tuberculosis, also known as "consumption", is a chronic infectious disease caused by the infection of Mycobacterium tuberculosis (commonly known as Mycobacterium tuberculosis). The part often invaded by Mycobacterium tuberculosis is the lung, which is called tuberculosis. The clinical manifestations of tuberculosis are various, and the early symptoms are mild and atypical. It is easy to be confused with other respiratory diseases, such as tracheitis and pneumonia, and it is often ignored, which leads to the delay of medical treatment. Cough, expectoration, hemoptysis or bloodshot sputum are the main symptoms of pulmonary tuberculosis. Most patients with pulmonary tuberculosis have hemoptysis with blood in sputum, and a few patients have hemoptysis with big mouth. In addition, chest tightness, chest pain, low fever in the afternoon, night sweats, general weakness, loss of appetite or weight loss are also common symptoms of tuberculosis.

(2) Prevention and control suggestions

1. Take tuberculosis examination as a compulsory item for physical examination of teachers and students.

2. Do not spit everywhere, cover your mouth and nose when coughing or sneezing, and wear a mask to reduce the spread of tuberculosis.

3. After suspicious symptoms of pulmonary tuberculosis appear or are diagnosed as pulmonary tuberculosis, you should take the initiative to report to the school, and don’t hide your illness or attend classes with illness.

4. Develop the habit of frequently opening windows for ventilation; Do a good job in campus environmental sanitation, and eliminate the dead corner of sanitation.

5. Ensure adequate sleep, reasonable diet, strengthen physical exercise and improve the ability to resist diseases.

Fourth, dengue fever

(A) disease science

Dengue fever is an acute mosquito-borne infectious disease caused by the spread of dengue virus through mosquito bites. Dengue fever has the characteristics of typical importation, suddenness, rapid spread, high incidence, general susceptibility of the population and high mortality of a few severe cases. The clinical features are sudden onset, high fever (sometimes up to 39℃), general muscle pain, joint pain, extreme fatigue, and some patients may have rash, bleeding tendency and lymph node enlargement. At present, the epidemic situation of dengue fever in Southeast Asia, South America, Africa and other places is more serious, and cases of dengue fever have appeared in Yunnan, Guangdong, Zhejiang, Hainan and other regions in China. At present, there are no vaccines and specific therapeutic drugs that can prevent the disease. The focus of treatment is to control pain with painkillers, usually acetaminophen (paracetamol).

(2) Prevention and control suggestions

Avoiding being bitten by mosquitoes is the key. Try to choose light-colored long-sleeved trousers and use mosquito repellent or other mosquito repellent drugs when going out.

2. Screen windows and screen doors should be installed in the residence. You can use mosquito-repellent incense, mosquito-repellent aerosol, etc. in the hotel room before going out. Even in high-end hotels, you should pay attention to indoor mosquito killing. Avoid staying in the dark and humid outdoors such as grass, shade and gazebo for a long time.

3. If symptoms appear, see a doctor in time. If you come back from dengue endemic areas (Yunnan, Guangdong, Zhejiang, Fujian and other domestic endemic areas, Southeast Asia, South America, Africa and other overseas endemic areas), please pay attention to your own health observation. If you have a persistent high fever within 2 weeks, accompanied by symptoms such as headache, orbital pain, muscle and joint pain, nausea, vomiting, rash, etc., you should go to a regular hospital as soon as possible, and inform the doctor of his recent residence history and remind him that he may have dengue fever; When staying at home or in hospital, do a good job in mosquito isolation (especially within 5 days after onset), including using mosquito nets, screen doors and screens, wearing long-sleeved underwear, spraying mosquito repellent and other measures to reduce unnecessary outdoor activities and prevent further spread.

V. Covid-19 infection

(A) disease science

At present, XBB series variants of Omicron subtype have become dominant in most provinces in China, and this trend is likely to continue in the future. The National Bureau of Disease Control and Prevention also said that the epidemic situation of COVID-19 in China is generally at a low level and in a wave-like fashion recently, and the epidemic situation has brought less pressure to local medical systems, so there will be no large-scale epidemic in the short term. However, it should be noted that cases of multiple infections with COVID-19 are more common. Through the search, we can find that the number of COVID-19-infected outpatients in hospitals has increased recently, and most patients are infected with Covid-19 or influenza virus.

(2) Prevention and control suggestions

1. Actively vaccinate. Elderly people aged 60 and above, people aged 18-59 with serious basic diseases, people with low immune function, people with high risk of infection, and people who have completed basic immunization or have been infected with Covid-19 should be actively vaccinated to further strengthen their autoimmune ability.

2. Pay attention to personal protection. Residents should wear masks in their daily trips, minimize unnecessary gatherings and keep social distance. Maintain good personal and environmental hygiene, wash hands frequently, often ventilate, pay attention to rest, pay attention to nutrition and enhance physical fitness.

3. Use drugs rationally and see a doctor as needed. After infection, residents should take corresponding treatment measures according to the severity of their own symptoms, implement self-care at home, reduce contact with their roommates, rationally use symptomatic drugs according to relevant guidelines, do a good job in health monitoring, and go to medical institutions in time if the condition worsens.

Six, monkeypox

(A) disease science

Monkeypox (Mpox) is a viral zoonotic infectious disease caused by Mpox virus. The main clinical manifestations are fever, rash and lymphadenopathy. Recently, many provinces and cities in China reported cases of monkeypox. Monkeypox cases are mainly men who have sex with men. Recently, there have been some cases of infection among women and medical staff.

(2) Prevention and control suggestions

1. Pay close attention to the epidemic information of monkeypox in the local area or travel destination in time to avoid direct contact with wild animals in high-incidence countries. Avoid catching, slaughtering and eating local animals raw.

2. Good hygiene habits, frequent cleaning and disinfection, and good hand hygiene.

3. If you find sex with a rash (especially in genitals, perianal parts, etc.), avoid close contact with it. Using condoms can’t completely prevent monkeypox virus infection.

4. The interpersonal transmission of monkeypox is mainly among men who have sex with men. It is suggested that men who have sex with men actively understand the knowledge of monkeypox prevention to avoid or reduce high-risk behaviors.

5. If you have symptoms such as fever, rash and lymphadenopathy of unknown reasons, you should take the initiative to seek medical treatment.

Seven, dog injury

(A) disease science

Rabies is a zoonotic acute infectious disease. Once it breaks out, the mortality rate is close to 100%. According to the data released by the World Health Organization (WHO), rabies still kills 59,000 people worldwide every year, and one person dies of rabies every 9 minutes, and 99% of the cases are caused by dog bites. Main symptoms (rabies): fear of water, fear of wind, pharyngeal muscle spasm and progressive paralysis. Raising awareness of rabies prevention, vaccinating dogs and strengthening post-exposure treatment of human rabies in epidemic areas are the most effective rabies prevention measures at present, and it is also the global consensus on rabies prevention.

(2) Prevention and control suggestions

1. Pet dog owners must consciously raise dogs in accordance with the law, vaccinate cats and dogs, and use leashes when going out to avoid dogs hurting people and spreading rabies virus.

2. Rabies can be prevented and cured. If you are scratched or bitten by a dog/cat, even if the wound is small, you should not be careless. You should seek medical advice in time. It is recommended to go to a medical institution with relevant qualifications for treatment, and do a good job in handling rabies after exposure according to the wound condition and personal immunization history.

3. After being scratched or bitten by a dog/cat, the individual should give first aid: if the wound is deep, especially the bleeding wound, you should first press the wound with a clean cloth to stop bleeding, and then rush to the hospital; If the wound surface is shallow or bleeding is not much, you can first clean the wound with flowing water or soapy water for 15 minutes, then use a clean paper towel to absorb the residual liquid at the wound, and then cover the wound with a clean cloth and seek medical attention as soon as possible. In addition to preventing rabies, we should also guard against other wound infections, such as tetanus infection.

4. Old people and children should receive more protection. Because the elderly and children have weak self-protection ability and lack of awareness of risk prevention, the incidence of animal injuries is high.

Sudden cardiac death (SCD) is an unpredictable natural death caused by heart, accounting for about 80% of sudden death. The main manifestations are acute onset, with more males than females. A variety of heart diseases can lead to sudden death, especially those with organic basic cardiovascular diseases or related risk factors. Patients may have a history of heart disease or heart disease in the past. At present, it is recognized that most of the deaths within one hour of onset are sudden cardiac death.

According to the China Cardiovascular Disease Report released in 2019, there are 544,000 cases of sudden cardiac death in China every year.

1. Coronary artery disease

It mainly includes coronary heart disease (coronary atherosclerotic heart disease), acute myocardial infarction, coronary thrombosis, embolism or spasm, coronary arteritis, congenital coronary artery dysplasia, etc., among which coronary heart disease is the most common.

As the most common cause of sudden death, coronary heart disease is seen in acute coronary syndrome (including acute myocardial infarction and unstable angina pectoris). According to the American Heart Association, 25% of patients with coronary heart disease take sudden cardiac death as the first clinical manifestation. According to the domestic literature, 80% of adult deaths from sudden cardiac death are related to acute coronary syndrome. These patients died of acute myocardial ischemia.

The etiological basis of coronary heart disease is atherosclerosis, which leads to the decrease of coronary blood flow and myocardial perfusion. Under the inducement, acute coronary spasm or microcirculation embolism can occur, causing acute myocardial ischemia, causing electrophysiological disorder, leading to malignant arrhythmia and even sudden cardiac death.

2.cardiomyopathy

Hypertrophic cardiomyopathy is the most common cause of sudden cardiac death in cardiomyopathy. Hypertrophic cardiomyopathy (HCM) is a complex hereditary cardiomyopathy characterized by thickening of left ventricular wall, which has various clinical and genetic manifestations. It is a common cause of sudden death in adolescents, with a high missed diagnosis rate and 50% family history.

The research shows that the risk of sudden cardiac death such as having a history of ventricular tachycardia attack, severe left ventricular wall hypertrophy (≥30mm), unexplained syncope, family history of sudden cardiac death and exercise-related hypotension is obviously increased. It is suggested that all patients with family history of sudden death should be screened by echocardiography.

3. valvular disease

Cardiac valvular disease is also one of the risk factors of sudden cardiac death, including mitral stenosis and/or insufficiency, aortic stenosis and/or insufficiency, infective endocarditis, mitral valve prolapse (MVP) or chordae tendineae rupture. For example, severe aortic stenosis can cause a serious decrease in blood flow into the aorta and cardiac output, leading to sudden cardiac death.

In China, the incidence of valvular heart disease is high, which is mainly caused by rheumatic diseases, trauma, degeneration, congenital malformation, inflammation and other reasons. The structural function of one or more valves is abnormal, resulting in stenosis and/or insufficiency of the valve orifice.

4. Structural heart disease

Structural heart disease is a general term for a large class of diseases caused by abnormal heart structure, which mainly includes: congenital heart structure abnormality, valve abnormality, coronary artery dysplasia, acquired valve disease and so on.

Congenital cardiovascular diseases mainly include atrial septal defect, ventricular septal defect, patent ductus arteriosus, coarctation of aorta, congenital aortic or pulmonary valve stenosis, tetralogy of Fallot and so on. Such diseases increase the risk of sudden cardiac death. In particular, patients with left-to-right shunt congenital heart disease who develop to Eisenmenger syndrome and complex congenital heart disease are more prone to sudden cardiac death.

Abnormal coronary artery is the main cause of sudden death in young people. Especially after strenuous exercise. The clinical manifestations are angina pectoris, arrhythmia, syncope and even sudden cardiac death after strenuous exercise. Therefore, for special people who have uncomfortable symptoms after exercise, athletes and so on, congenital coronary artery dysplasia should be screened out.

5. Aortic disease

Aortic disease is one of the important factors leading to sudden cardiac death, and its main pathogenesis is fatal ischemia of target organs caused by aortic rupture and involvement of important branches. Among them, Stanford A aortic dissection is the most dangerous, and the main causes of sudden cardiac death include: aortic rupture, pericardial tamponade, dissection involving coronary artery leading to large-scale myocardial infarction, and involvement of brachiocephalic artery leading to cerebral infarction.

6. Pulmonary embolism

Pulmonary thromboembolism is a common emergency in cardio-pulmonary vascular diseases, and its incidence and mortality are extremely high.

The embolus source of pulmonary embolism can be endogenous or exogenous, and the embolic site is mainly in the trunk or main branch of pulmonary artery. Clinically, pulmonary embolism thrombus mainly comes from venous system or right atrial appendage. When patients have pulmonary embolism, pulmonary circulation disorder can occur in a short time, and sudden cardiac death can occur in severe cases.

In daily life, sudden cardiac death caused by pulmonary embolism is most common in "economy class syndrome", that is, the lower limbs are in a state of braking for a long time, which leads to venous thrombosis. Once a large thrombus falls off, it will lead to acute pulmonary embolism, and then sudden cardiac death can occur.

In addition, a considerable number of patients’ thrombi come from the right atrial appendage, mainly due to atrial fibrillation, so for such patients, it is also necessary to be alert to the occurrence of sudden cardiac death caused by pulmonary embolism.

7. Abnormal cardiac electrophysiological activity

Abnormal primary ECG or abnormal ion channels can induce sudden cardiac death, such as sinoatrial node lesions and abnormal cardiac conduction system (Lenegre disease or Lev disease, WPW syndrome, Q-T interval extension syndrome). This is an important cause of sudden death of teenagers.

Once the cardiac electrophysiological abnormality occurs, it may induce cardiac pacing conduction disorder, eventually leading to complete atrioventricular block, and even fatal arrhythmia such as ventricular tachycardia and ventricular fibrillation may occur, which may lead to insufficient blood output from the heart to brain tissue and the whole body, resulting in shock and syncope. If cardiac arrest lasts for 5 minutes, it can cause irreversible brain tissue damage and death, which will eventually lead to sudden cardiac death.

Sometimes, viral infection and other diseases may also involve the cardiac electrical conduction system, which increases the risk of sudden death of patients.

8. Explosive myocarditis

Early mortality is extremely high, which is another important cause of sudden cardiac death in children and young adults. The early symptoms of myocarditis are very similar to the common cold, only "a little uncomfortable", which is difficult to attract attention.

9. Kawasaki disease

The etiology is not clear yet. At present, it is considered that some patients are immune-mediated systemic vasculitis triggered by various infectious pathogens (viruses, bacteria, etc.). Kawasaki disease mostly occurs in children, which is one of the main causes of sudden death of children. Having Kawasaki disease in childhood can also cause myocardial infarction in adults.

10. Others

Other causes of sudden cardiac death mainly include: acute pericardial tamponade, intracardiac thrombosis, electrolyte disorder, sleep apnea and gene correlation.

It’s winter.
High incidence of respiratory infectious diseases
But can you tell what kind of infection it is?
Collect it! This article answers your questions!

　　1. What are the clinical manifestations of mycoplasma pneumoniae infection?
　　Mycoplasma pneumoniae is mainly infected by respiratory tract, which can cause pneumonia, often accompanied by pharyngitis and bronchitis.
　　The onset of mycoplasma pneumoniae infection is generally slow, and patients often have chills, fever and dry cough, which may be accompanied by symptoms such as stuffy nose, fatigue and headache. Mycoplasma pneumoniae infection has certain self-limitation. In recent years, the proportion of refractory mycoplasma pneumonia and severe mycoplasma pneumonia has increased among school-age children.

　　2. What are the clinical manifestations of respiratory syncytial virus infection?
　　In the early stage of respiratory syncytial virus infection, the main symptoms are upper respiratory tract infection, such as nasal congestion, runny nose, cough and hoarseness, and most of the symptoms will disappear by themselves in 1-2 weeks.
　　A few cases can develop into lower respiratory tract infections such as bronchiolitis or pneumonia, which are more common in infants under 2 years old.

　　3. What are the clinical manifestations of adenovirus infection?
　　Adenovirus infection has various clinical manifestations, which can cause common cold, bronchitis and pneumonia, diarrhea and gastroenteritis, conjunctivitis, cystitis and some nervous system inflammation.
　　People with chronic respiratory diseases, heart diseases or low immune function may have serious clinical symptoms after being infected with adenovirus.

　　4. What are the clinical manifestations of rhinovirus infection?
　　Rhinovirus infection can cause symptoms of upper respiratory tract infection such as nasal congestion, runny nose, sneezing, sore throat, fever or cough, and can also lead to wheezing and asthma aggravation in children.
　　Infants or children with basic diseases infected with rhinovirus may cause lower respiratory tract infections such as bronchiolitis and pneumonia. The infection of rhinovirus in the elderly can increase the risk of chronic obstructive pulmonary disease, and the infection of hospitalized patients can lead to prolonged hospitalization.

　　5. What are the clinical manifestations of human metapneumovirus infection?
　　The incubation period of human metapneumovirus infection is 3~5 days, which often causes symptoms of upper respiratory tract infection, such as fever, cough, nasal congestion, runny nose and hoarseness, which are slightly self-limited, and the symptoms gradually ease in about 1 week.
　　Children, the elderly and immunocompromised people may have bronchiolitis, pneumonia or acute respiratory distress syndrome after infection.

　　6. What is the difference between the clinical manifestations of influenza, mycoplasma pneumoniae infection and common cold in children?
　　The clinical manifestations of influenza, mycoplasma pneumoniae infection and common cold in children are different, and the main differences are shown in the table below.
　　The clinical manifestations of respiratory tract infectious diseases are usually not specific, and there are individual differences among patients, so they can not be differentiated only by symptoms and signs, and usually need laboratory tests to diagnose.

　　

　　7. What are the commonly used therapeutic drugs for respiratory tract infection pathogens in adults?
　　Recently, viruses and mycoplasma are the main pathogens causing respiratory tract infections. At present, there are mabaloxavir, oseltamivir and palamivir for influenza virus, nematevir/ritonavir, sennotvir/ritonavir, Monola vir and deuterium hydrobromide for Covid-19, and macrolides (such as azithromycin), fluoroquinolones (such as moxifloxacin and levofloxacin) and tetracyclines (such as doxycycline and levofloxacin) for mycoplasma.
　　Some infections caused by viruses or mycoplasma will be secondary to bacterial infections. At this time, it is necessary to use antibiotics reasonably under the guidance of doctors to avoid drug resistance. Commonly used antibiotics include penicillins (such as amoxicillin/clavulanic acid), cephalosporins (such as cefaclor, cefuroxime and cefdinir), fluoroquinolones (such as moxifloxacin and levofloxacin) and macrolides (such as azithromycin). It is worth noting that the above drugs are all prescription drugs and need to be used under the guidance of a doctor.
　　If you are self-tested for influenza virus antigen or Covid-19 antigen, and have serious high-risk factors such as age over 65, body mass index (BMI) over 40kg/m, basic diseases (such as chronic obstructive pulmonary disease, tumor, immune system diseases, etc.) or pregnancy, it is suggested to take orally anti-influenza drugs oseltamivir or mabaloxavir or oral anti-Covid-19 drugs within 48 hours of onset. If respiratory symptoms get worse, you should seek medical advice promptly.

　　8. What drugs are commonly used by children to treat pathogens of respiratory infections?
　　Children infected with influenza virus can take neuraminidase inhibitors such as oseltamivir, and children over 5 years old can also choose RNA polymerase inhibitors such as mabaloxavir.
　　After children are infected with mycoplasma pneumoniae, the first choice is macrolide drugs, such as azithromycin, clarithromycin and roxithromycin. The alternative drugs are new tetracyclines (such as doxycycline and minocycline) and quinolones. Tetracyclines are only used for children over 8 years old because they may cause yellowing of teeth and hypoplasia of enamel.
　　Children and adolescents under the age of 18 who use quinolones need doctors to strictly evaluate the indications and pay attention to the side effects of the drugs.

　　9. What are the precautions in diet during respiratory infection?
　　During the period of respiratory infection, on the one hand, due to fever, cough, fatigue and other conditions, the patient’s appetite decreased compared with usual; On the other hand, respiratory tract infection leads to the increase of energy consumption and the increase of energy demand.
　　Therefore, it is particularly important to supplement nutrition in a reasonable and balanced way and ensure the supply of energy. People with decreased digestive function can eat less and eat more to ensure adequate energy intake.
　　(1) Recommended food:
　　① Highly nutritious and digestible foods: such as lean meat, chicken, fish, tofu, etc. These foods are rich in protein, which helps to repair body tissues.
　　2 foods rich in vitamins: fresh fruits and vegetables, such as oranges, kiwis, carrots and spinach, are rich in vitamin C and other antioxidants, which helps to enhance immunity.
　　③ Whole grains and foods rich in cellulose, such as oats, whole wheat bread and brown rice, provide necessary energy and cellulose.
　　4 Adequate water: Ensure adequate water intake, such as drinking water, juice or soup, which helps to keep the body water balance and relieve sore throat.
　　(2) Foods that are not recommended or need to be controlled:
　　Oily and spicy foods, high-sugar foods, caffeinated drinks, etc.

The new semester has arrived, and friends should start studying hard! In English learning, many grammatical problems will become a problem. Xiaobian will publish some articles about English spelling, punctuation, grammar, vocabulary description and writing tips one after another this semester, hoping to help English learning.

There are several differences in spelling between British English and American English. These differences are often due to the fact that British English often retains the spelling of the source language, such as French, while American English adjusts the spelling in order to correctly reflect the actual pronunciation of words.

If you want to write something for the British, you should only use British spelling. In a few cases, American spelling is also acceptable in British English, especially words ending in -ize/-ization. In this case, -ise/-isation or -ize/ization can be used in British English, but it is important to be consistent in an article and use one spelling from beginning to end.

Today, we list several major spelling differences and compare the spelling differences between British and American English.

1) Words ending in–re: English ends in–re; American style ends with -er.

2) Words ending in -our: English ends in -our; American usually ends with -or.

3) Words ending in -ize or -ise: In British English, verbs spelled with -ize or -ise are acceptable; In American English, it is always spelled -ize.

4) Words ending in -yse: In British English, this kind of verb is written as-yse; American English is always writing -yze.

5) Words ending in vowel+letter L: In British spelling, when a verb ends in vowel+letter L, if you need to add vowel, you will double write L; In American spelling, there is no need for double writing.

6) diphthongs’s spelling: In British English, diphthongs ae or oe are both two letters; In American English, they are all written as a letter e.

Tip: In American English, some specific words, such as archaeology, still retain the spelling of ae. This is the standard spelling method, and if it is only written as e, it is archeology, which is usually acceptable.

7) Nouns ending in -ence: nouns ending in -ence in British English are written as -ense in American English.

8) Nouns ending in–OGUE: English spelling is–OGUE; American spelling can be -og or -ogue.

This difference is not difficult to grasp. In American English, the writing of analogue is acceptable, but not universal; The spelling of catalog has become the standard form in the United States, and the writing of catalog is not uncommon; Dialogue is still more popular than dialogue.

brief Introduction of the content：

　

China Urban Statistical Yearbook is an informative annual publication that comprehensively reflects the social and economic development of China. China City Statistical Yearbook-2020 contains the main statistical data of social and economic development of cities at all levels in China in 2019.

　

This yearbook is divided into four parts: the first part is the national urban administrative division, which lists the distribution of cities in different regions and levels; The second and third parts are the statistics of cities above prefecture level and county level, including population, resources and environment, economic development, scientific and technological innovation, people’s life, public services and infrastructure. The fourth part is the appendix, which explains the main statistical indicators. It should be noted that since 1997, cities at or above the prefecture level and cities at or above the county level have adopted different statistical systems, and some indicators are not comparable between the two types of cities. Therefore, this yearbook divides the statistical data of cities at or above the prefecture level and cities at or above the county level into two independent parts.
