　　According to the survey, 42% of the poor households who set up their cards were poor due to illness. The "Thirteenth Five-Year Plan" period is a period of getting rid of poverty and attacking hard bones, attacking cities and pulling out villages. How can we get rid of the hard bones caused by illness?

　　This edition launched a series of reports on "Stopping Poverty Caused by Illness" today, introducing the exploration and experience of various places. The first part introduces the solution path of Daning County, Shanxi Province: helping and strengthening county-level hospitals, improving the ability of diagnosis and treatment at the grassroots level, and reducing the burden of medical treatment for ordinary people; At the same time, establish front-end control, carry out health science popularization and high-risk population screening, actively treat the disease before it happens, and reduce the chance of people getting sick.

　　"County hospitals account for 70% of internal medicine patients, and 80% of them are patients with cardiovascular and cerebrovascular diseases." Daning, Shanxi Province was originally a poor county, with no resources on the ground and no mineral deposits underground. Unexpectedly, it suffered from this kind of "rich disease" that occurred frequently in economically developed areas.

　　Getting rid of poverty in an all-round way, getting poor due to illness and returning to poverty due to illness are unavoidable "hard bones". According to the survey, 42% of the poverty-stricken households who set up the card are poor due to illness. What should a small mountain county with "rich disease" do? Where is the difficulty? The reporter conducted an interview.

　　Eating less meat, vegetables and salt will bring cardiovascular and cerebrovascular diseases.

　　Daning’s turnaround in stopping poverty caused by illness began in 2015. In this year, the Provincial Health Planning Commission organized experts from the First Hospital of Shanxi Medical University, the Provincial Children’s Hospital and the Linfen People’s Hospital to form the Daning County Health and Family Planning Poverty Alleviation Task Force, and sank to the county hospital. Counterpart assistance.

　　Li Yang is the deputy chief physician of the Department of Neurology, the First Hospital of Shanxi Medical University. After arriving in Daning, he was appointed as the vice president in charge of medical treatment. He found that "70% of the internal medicine patients in county hospitals, 80% of whom are patients with cardiovascular and cerebrovascular diseases."

　　According to Li Yang’s analysis, the reason for the frequent occurrence of this disease lies in diet. "If the diet is heavy in oil and salt, it is easy to suffer from hypertension and hyperlipidemia, and hypertension is the primary risk factor for cardiovascular and cerebrovascular diseases. Generally speaking, eating meat and vegetables is less, and salt is heavy before eating. The lack of health concept leads to low awareness rate, low control rate and high prevalence rate of hypertension in the local area. "

　　Sure enough, many patients in the inpatient department are like this. 82-year-old Li Xiue came to the hospital after feeling dizzy and uncomfortable, and found that her blood pressure reached 140— 150。

　　Li Yang asked her, "How often do you eat meat? Do you eat much food? " Li Xiue said, "Meat can’t be eaten once a month, vegetables are rarely eaten, and salt is heavy." Hearing this, Cao Huiting, a 58-year-old son, was embarrassed. "Last year, more than 10 mu of land was confiscated, and seed fertilizers were lost. This time, I also borrowed money to be hospitalized."

　　45-year-old Wang Aimei and Li Xiue live next to each other. Her family has inherited hypertension, her mother died of cerebrovascular disease, and her father also suffered from cerebrovascular disease. She takes medicine every day, but she still likes to eat salt every meal.

　　The combination of poverty and illness makes it easy to return to poverty due to illness. According to statistics, Daning County has a total population of 69,000, including 36,000 poor people, and nearly 10,000 people are poor due to illness or disability, accounting for 28% of the total poor people.

　　Looking at the whole country, Daning may not be an isolated case. To get rid of poverty, health intervention should suit the remedy to the case, especially to prevent poor counties from getting "rich disease"

　　On April 5, following Daning, the Provincial Health Planning Commission sent medical poverty alleviation teams to Yonghe County, Wuzhai County and Xingxian County, which are located in the concentrated and contiguous areas of Luliang Mountain. It is reported that the implementation of medical poverty alleviation in Shanxi and the prevention of returning to poverty due to illness through health intervention have entered the normalization.

　　Helping county hospitals to alleviate the difficulty and expense of seeing a doctor

　　Poor county poor medical care, first arrived at the county hospital, Li Yang insomnia for half a month.

　　Why? There is no fixed doctor in the emergency department for many years, no pathological room for regular work, the supply room can not meet the needs of clinical departments, and the laboratory department has not carried out bacterial culture for many years, which can not provide biological support for hospital feeling and clinical antibiotic use; The inpatient department is an old building in the 1980 s, with no elevator and no bathroom; The operating room space is narrow, which leads to unreasonable layout and incomplete functional areas.

　　Now that half a year has passed, the county hospital has greatly improved its department settings, medical procedures and diagnosis and treatment norms. Lei Ruifang, the president of the county hospital, is happy. "Without help, I was promoted from a second-class hospital to a second-class hospital?" Don’t even think about it! "

　　According to reports, in view of the weak links in county hospitals, the task force has tackled key problems in multiple disciplines and established and improved intensive care units, emergency rooms, infectious diseases departments, neonatal wards and equipment departments; Standardize the layout and process of operating room, delivery room, disinfection supply room and abortion room, basically achieve reasonable partition of cleaning and pollution, and so on.

　　With the help of the task force, the clinical skills of internal medicine in county hospitals have been improved, standardized training has been given to the diagnosis and treatment of nervous system diseases, and a standardized process of thrombolysis for emergency stroke has been established, which initially meets the conditions of intravenous thrombolysis for patients with cerebral infarction time window and improves the treatment level of cerebrovascular disease in the acute stage.

　　At the same time, the hospital has also set up a patient service process with eye-catching signs, providing patients with convenience measures such as medical guidance, health education materials, drinking water, parking, wheelchairs and accompanying inspections.

　　Wang Yuhong, deputy director of the County Health Bureau, said, "Health assistance has really played a big role. People now go to the county hospital for medical treatment, all of which are diagnosed by experts in the province, and the proportion of reimbursement is also high. The medical level of county hospitals has improved. Patients choose to go to county hospitals for medical treatment and hospitalization, which not only facilitates medical treatment, but also saves transportation and accommodation expenses incurred by going to other places for medical treatment, alleviating the difficulty and expensive medical treatment for ordinary people. "

　　According to reports, only two diseases, cerebral infarction and caesarean section, are taken as examples: the cost of going out for medical treatment is 2,500 yuan and 1000&mdash higher than that of county hospitals; 1500 yuan, and the reimbursement rate is 10% lower. After the medical level of county hospitals improved, the number of outpatients increased from 29,001 in 2014 to 33,942 in 2015, an increase of 17%.

　　Make up lessons in health, and screen high-risk groups for treatment.

　　Prevention is the only way to get rid of the root cause. In 2015, Daning formulated the "Health Education Work Plan" and built a county (CDC) — Township (township hospitals) — A new model of integrated health education in villages (health huts).

　　From this, the first healthy hut in the county was built in Rugu Village, Taide Township. Villagers can measure their blood pressure, measure their height and weigh themselves in the hut, and they can also gain knowledge about healthy eating and prevention of chronic diseases.

　　Wang Yinke, director of the County Center for Disease Control and Prevention, said that with a healthy hut, disease control and prevention will have a "stagnation point". Disease control and prevention will join hands with township hospitals to carry out health science popularization, gradually cultivate rural public health personnel and ignite the flames of rural health communication.

　　At the same time, the county hospital introduced the stroke prevention project of the National Health and Family Planning Commission, actively established the database of high-risk groups of cardiovascular and cerebrovascular diseases among the elderly in the county, and implemented full coverage grid management, in order to improve the prevention and control of cerebrovascular diseases in the county and reduce the incidence and recurrence rate of cerebrovascular diseases. At present, the pilot project has been completed in Taide Township. A total of 1,296 people over 40 years old have been screened and 268 high-risk people have been found.

　　Li Yang said that according to the intervention and management network system linked at the county and village levels, Daning will conduct inspections every two months for the screened high-risk groups of cardiovascular and cerebrovascular diseases, understand the control of risk factors, improve electronic files and report them to the internal medicine department of the county hospital, and then the county hospital will provide technical guidance on the inspection results; The county hospital carries out blood sugar and blood lipid test and blood vessel examination once a year, and the First Hospital of Shanda University carries out intervention effect evaluation and treatment guidance.

　　In the next step, county hospitals will explore the implementation of the family doctor system for high-risk groups, and physicians will contract high-risk groups in various towns and villages in pieces to implement full coverage grid management, leaving no blank areas for prevention and control. In case of acute attack of cardiovascular and cerebrovascular diseases or poor control of risk factors, you can directly contact doctors in county hospitals for treatment, so as to move forward the prevention and control barrier, truly improve the level of prevention and treatment of cardiovascular and cerebrovascular diseases in the county and reduce the medical burden of the people.

Build a safe water supply barrier to ensure that water is safe.

The continuous high temperature and rainless weather has caused the city’s drought prevention and relief work to face a severe situation. The Municipal Flood Control and Drought Relief Headquarters issued a circular, and at 9: 00 on August 14, the city-wide level IV emergency response was launched.

Yesterday, the reporter learned from Liuyang Economic Development Zone Water Company that the daily water supply of the park has been rising since the dog days. On August 16th, the water consumption reached 178,000 tons, nearly 10,000 tons more than the highest daily water consumption last year, and the water demand is still rising.

"People’s livelihood is no small matter. In any case, we must guarantee the production and living water of Yangxin City enterprises and residents." Zhang Juanjuan, chairman of Liuyang Economic Development Zone Water Company, stressed many times when deploying the summer peak water supply work.

Ensure water supply, maintain equipment operation, strengthen inspection of production equipment, encrypt the frequency of water quality inspection, strengthen water purification treatment, and advocate water conservation … Since June, Liuyang Economic Development Zone Water Company has arranged a number of measures in advance around the summer peak water consumption to ensure that enterprises can use water without worry.

Liuyang Rong Media Center reporter Zhang Yonghong correspondent Li Ning

Steady supply

Strengthen the inspection of water supply equipment to ensure water supply.

At 4 o’clock on the afternoon of August 16th, Jinyang No.1 Water Plant, the hot sun was roasting the earth, the outdoor temperature was as high as 38℃, and the heat waves burst. The staff of the water plant were busy inspecting the production equipment.

Water plants, water pumps, motors, hydraulic valves, frequency converters … The more water supply equipment and supporting facilities there are, the longer they stay. In the sauna-like working environment, the mind of the staff remains highly awake and carefully checks every screw and dial.

According to the relevant person in charge of Liuyang Economic Development Zone Water Company, in order to ensure a smooth water supply peak, four water plants in Jinyang New City have been started simultaneously, and Jinyang No.1 Water Plant is close to full capacity.

"The temperature is high, the equipment runs for a long time, and the heat dissipation is not enough, which is easy to break down. In order to find and solve problems in advance and avoid failures, we have increased the number of inspections and increased the maintenance of equipment. " According to the person in charge, in order to ensure the normal and safe operation of the equipment, at present, the four water plants strictly implement the 24-hour duty inspection system, and the duty personnel conduct inspections every 2 hours. For inspection workers, high-temperature roasting and indoor "sauna" have become commonplace, and they walk nearly 20,000 steps a day.

Water quality preservation

Take samples every hour to ensure the safety of water quality.

In the continuous high temperature weather, the water level of Laodao River is reduced, the flow rate is reduced, and the flow velocity is slow. Floating objects, fallen leaves and dead branches in the river flow to the intake, which may cause the intake grille to be blocked and affect the quality of raw water.

On the afternoon of August 16th, Huang Youtong, Luo Qingjun, Deng Jie, Li Chengquan and others, the staff of No.1 Water Plant of Liuyang Economic Development Zone Water Company, came to the river to prepare to go down the river to clean up the sundries near the water intake. They change their work clothes and put on life jackets. A straw hat, a rake and a pair of hands are all their "equipment".

Bend over, salvage, get up … They kept repeating these actions in the hot sun, and the boat was gradually filled with debris. After more than 20 minutes, the water surface near the water intake finally became clean and unobstructed.

"Ensuring smooth water intake is the basis for normal water supply during peak hours." Huang Youtong said that during the dry season, they have to clean up every two days or so.

In order to ensure the continuous and stable water quality of water supply in hot weather, Liuyang Economic Development Zone Water Company has also increased the frequency of testing. Samplers sample and test source water, factory water, pipe network water and terminal water once every hour to keep abreast of water quality changes.

In addition, the water plants of the water company have also organized staff to clean the process tanks such as sedimentation tanks and filter tanks for many times to ensure the cleanliness of the process tanks and avoid the influence of sediment deposition on the water treatment process effect and water supply quality.

Excellent service

The maintenance team is on standby 24 hours a day to solve the water problem in time.

On the afternoon of August 15th, some people reported that a water supply supervisor in Yongtai Road had a water leakage problem. In order to avoid the impact of water stoppage and maintenance during the daytime peak period on the water consumption of enterprises and residents, the maintenance team of the business service center of Liuyang Economic Development Zone Water Company worked overtime at night for emergency repair, and the water pipe maintenance was completed at midnight.

In order to deal with water pipe leakage and other problems in time, maintenance personnel are on standby 24 hours a day, fighting for maintenance in such a hot and humid working environment as a narrow water meter well.

As hot as the hot weather at present, there is also the service enthusiasm of the staff of the business service center of Liuyang Economic Development Zone Water Company. The person in charge of the business service center said that during the peak period of water use, the number of water consultation and repair calls also increased sharply. In order to ensure the water demand of residents in Jinyang New Town and practice the practical requirements for the people, the staff of the service center patiently answered all kinds of water-related consultation and repair calls, recorded and classified the relevant information, and timely fed it back to the relevant departments of the company to ensure that every problem could be accepted in time.

"If there is a water problem, residents of Jinyang New Town can call our 24-hour service hotline at any time, and we will do our best to provide services." According to the person in charge, the service hotlines are 0731-83280619, 8322002 (Liuyang Economic Development Zone), 0731-83202583 (Yongan Town), 0731-8324715 (Jiaoxi Town) and 0731-83280658 (Dongyang Town).

These days, friends, friends and WeChat groups can always see everyone’s concern about nucleic acid detection and discuss the COVID-19 epidemic. Since then, nucleic acid detection has become a high-frequency word. But do you really know about nucleic acid testing? What is the nucleic acid strategy under the most severe and complicated situation faced by Chongqing since the COVID-19 epidemic?

In this issue of "Knocking on the Blackboard", Xiaobian will focus on these issues.

The role of nucleic acid detection—It is recognized by the medical communityThe "Gold Standard" for Diagnosing Covid-19

Why do you want to do nucleic acid testing? On November 27th, at the 150th press conference on the prevention and control of COVID-19 epidemic in Chongqing held by Chongqing Municipal Government Information Office, Li Pan, deputy director of Chongqing Municipal Health and Wellness Committee, once again stressed clearly:

Nucleic acid detection is the "gold standard" recognized by the medical community in diagnosing Covid-19. It is an important measure to quickly find infected people, lock the source of infection in time, and quickly cut off the route of transmission. It is a key measure to realize early detection, early reporting, early isolation and early treatment.

(Related links: press conference, responding to concerns-will you be infected in the process of making nucleic acid? What is the difference between regional nucleic acid and expanded nucleic acid?)

At the 147th press conference on November 22nd, Luo Fei, an expert from Chongqing CDC, made an analogy.

If antigen testing is an auxiliary team and nucleic acid testing is the main player; antigen testing is an attack by innuendo, then nucleic acid testing is the final word.

(Related links: press conference, responding to concerns-which is more useful, antigen or nucleic acid? Is the nucleic acid test result true?)

From a professional point of view, the positive result of nucleic acid detection can be regarded as the same as the result of virus culture and then detection. Covid-19 nucleic acid detection is to select two or three characteristic sequences on the virus genome, copy and amplify them, and then detect and compare them, which is what we often call double-target or triple-target detection.

Because the conservative gene sequence of virus is usually selected as the target gene in nucleic acid detection, even if the virus mutates, it has little effect on the detection ability. Nucleic acid detection requires high detection reagents, detection facilities and equipment, and requires professionals to complete more complicated processes such as collection and detection.

---

• Xiaobian analogy-
• Nucleic acid testing is like "raising a baby chicken". When the chick is very young, most people can’t see the male and female, but when the chick is raised, you will know it when you look at the comb.
• Why does it take several hours for nucleic acid testing to produce results? In fact, it is to cultivate viruses, or to raise chickens. Covid-19 nucleic acid detection is equivalent to using cockscomb as a feature to identify male and female, which is the so-called "target gene". At the same time, it is not easy to misjudge if it is characterized by cockscomb, but it is easy to misjudge if it is characterized by chicken feet and tail, so cockscomb is the so-called "conservative gene".

---

At the 151st press conference on November 27th, Liao Pu, director of the Laboratory Department of Chongqing People’s Hospital and deputy director of Chongqing Clinical Laboratory Center, also explained the nucleic acid detection.

(Related links: Why is nucleic acid detection the "gold standard"? What about "false yin" and "false yang")

At present, Covid-19 nucleic acid detection usually uses fluorescence PCR amplification technology, and its principle is that viral nucleic acid is increased exponentially through one cycle, so as to realize Covid-19 nucleic acid detection. This is a very classic and reliable nucleic acid detection method, and it is a technology that won the Nobel Prize.

In the detection process, the yin and yang of the detection results are objectively judged by the circulating threshold of nucleic acid amplification, that is, Ct value. The Ct value is related to the viral load of the infected person. The lower the Ct value of the infected person, the higher the viral load of the infected person. Conversely, the higher the Ct value, the lower the viral load of the infected person.

For the report of positive results, according to the detection strategy, one or two other nucleic acid detection reagents that are more sensitive and amplify different regions will be used to detect the original samples when necessary, and the positive results will not be reported until they are confirmed, so sometimes the detection time is longer.

Although nucleic acid detection technology is the recognized gold standard in Covid-19, it is an internationally recognized detection technology for mature pathogens. However, the so-called "false negative" may appear in unreasonable sample collection, transportation and processing, too low virus droplets in the sample, variation of the target sequence to be detected or sequence change caused by other reasons.

For sudden and new subtype Covid-19, such as Omicron mutant, which has the characteristics of concealment, the optimal sampling time for detection may not be confirmed. In addition, in the process of sample collection and detection, pollution caused by aerosol will occur, resulting in false positive. By strengthening laboratory quality control, monitoring laboratory environment and equipment pollution, and multiple rounds of nucleic acid screening, we minimize the errors caused by technical reasons.

Strategies for nucleic acid detection-different strategies at different stages according to the needs of epidemic situation.

These days, users always leave messages asking questions. Why do you do nucleic acids in different areas?

Indeed, since November 1, especially since November 12, when the coordinated prevention and control of the central city was carried out and the epidemic annihilation war was launched, the Chongqing epidemic prevention and control headquarters adopted different nucleic acid detection strategies at different stages according to the needs of the epidemic situation.

For example, the social inspection has been carried out once every seven days, once every day and every other day. After the city launched the social clean-up attack, according to the deployment of classified attack, all districts and counties were divided into three categories: relatively stable epidemic situation, fluctuating platform period and severe situation, to carry out nucleic acid testing.

Li Pan spoke carefully at the press conference on the evening of November 26th. Under the provisions of the ninth edition and Article 20, various localities will formulate different strategies according to the situation of this area, street, community and even community. Specific to this round of epidemic in Chongqing:

At the beginning of the epidemic, the central city of annihilation was fought-

The epidemic situation is multi-point, multi-source and multi-chain. I don’t know where the potential infected people are, and the chain is unclear. For example, "I don’t know where the’ enemy’ is", then take the whole central city as a whole and carry out nucleic acid testing all over the region, and do it every day, which is to find out the potential infected people. After searching for a period of time, I marked a high-risk area.

Fight the tough battle in the central city in the stage of social clearing-

At this time, it is: high-risk areas should be zoned quickly, and nucleic acid testing should be carried out at the specified frequency in high-risk areas; in other areas, because there is still community transmission, it is necessary to "check every other day" and strive to promote social clearing.

Yuzhong, Jiulongpo, Jiangbei and Yubei made three rounds in three days-

Li Pan said at the press conference on the evening of November 26th that the epidemic situation in all districts of the central city was divided, and some districts added thousands of people a day, with a high proportion of society.

Therefore, just like the annihilation war at the beginning of the epidemic, Yuzhong District, Jiulongpo District, Jiangbei District and Yubei District decided to make three rounds in a row for three days, and continue to exert their strength and concentrate their efforts to find out the potential infected people and the risk sources in a short time.

Similarly, the same is true of Liangping, Dianjiang and Xiushan. The difference is that it is not the whole district (county), but the streets where the county is located and the streets involved in the epidemic.

Xiaobian said so much, we can see that the nucleic acid strategy must be a specific arrangement made according to the current epidemic situation. It is about strategy and actual situation. I hope parents will understand and support it.

Organization of nucleic acid detection-this is an important link, and the organizer must pay attention to it.

This point, Xiao Bian should remind the organization unit of nucleic acid detection, because it is really important.

The organization of nucleic acid detection directly affects the detection quality and screening effect. Staff organization, testing resource allocation, testing object organization, and centralized sampling or sampling by building, unit and floor are all important factors.

For example, on November 26th, some districts and counties reported that "nucleic acid test samples were left behind", which may affect the accuracy and quality of nucleic acid screening for whatever reason, indicating the importance of organizational work.

At the same time, there are still many people who are concerned about the organizational level of nucleic acid testing institutions and the professional ethics of staff, which will also directly affect the testing quality and screening effect.

For the sake of everyone’s health and this city, please ask the organizers of nucleic acid testing to follow the process, make the work meticulous and put the management in place! Please!

(Related links: press conference, responding to concerns-Is nucleic acid testing true or not? Are you sure?)

Can nucleic acid be infected? Everyone should take personal protection, so don’t worry about it.

This point, Li Pan also made a detailed introduction. In fact, you don’t have to worry about doing nucleic acid testing and being infected.

Statistics show that more than 60% of the newly infected people are residents of the same building, the same neighborhood and the same community. The route of infection is often in community activities, with acquaintances and friends, shopping together, and taking express mail together (among them, infected people), without protection or standardized protection and contact.

However, there are very few cases of infection directly in the queue of nucleic acid collection or in the process of nucleic acid collection, but the results of flow adjustment are not supported, so don’t worry.

For high-risk areas, there are positive buildings and units that are tested at home, not to mention worrying.

Look, really don’t worry too much. As long as everyone takes personal protection and adheres to the "one meter distance", this situation can be put an end to.

(Related links: do nucleic acid, remember "5321"!)

Supervision of nucleic acid detection-never be soft when it comes to the end, and please continue to supervise the general public.

On November 24th, at the 148th press conference, Dan Yanzheng, deputy mayor of Chongqing Municipal Government, commander of the municipal epidemic prevention and control command department and director of the comprehensive office, said: At present, the results of nucleic acid testing in the whole city are authentic, so please rest assured.

He said-

Chongqing Municipal Party Committee and Municipal Government have always attached great importance to the quality of nucleic acid detection. In this round of epidemic, in view of the laboratory quality problems with a large amount of detection and public concern, on the basis of monthly laboratory quality assessment and quality control spot check in the early stage, the Municipal Health and Health Commission strengthened management supervision, with municipal quality control experts "conducting daily inspections" and district and county experts "guiding at the station", participating in laboratory management throughout the process, and promptly urging and rectifying problems such as irregular management and process of individual laboratories.

For violations of laws and regulations, we will maintain a high-pressure situation, and immediately start the investigation procedure according to law for the detection errors reflected by the public. Once found, hell to pay.

Ability of nucleic acid detection-Thanks to the strong support of brother provinces and cities, the ability of nucleic acid detection in Chongqing has been enhanced.

Everyone must have noticed that the staff and volunteers of nucleic acid detection are very hard: airtight protective clothing is worn for most of the day or even a day; alcohol cleaning gloves are constantly rubbed, cotton swabs are torn open and carefully sampled …

Especially in the face of this round of large-scale epidemic and large-scale nucleic acid detection, the whole nucleic acid detection system in our city is facing the pressure of long-term and full-load operation, and there are problems such as staff fatigue, high-speed operation of nucleic acid system and obvious lack of detection ability.

In this regard, under the guidance and support of Chongqing Working Group of the State Council Joint Prevention and Control Mechanism, Chongqing has received strong support from some brother provinces and cities, which has enhanced the strength of nucleic acid detection in our city.

(Related links: Medical teams from 8 provinces and cities in China rushed to Chongqing and successively entered Cuntan and Yuelai Fangcang Hospital to carry out medical treatment.)

What should we do-participate in nucleic acid testing as required!

Li Pan said that the majority of medical workers are fighting hard, hoping to eliminate the doubts of some citizens through continuous efforts and higher-quality nucleic acid testing.

What should we do personally to support nucleic acid testing? It’s simple—

Participate in nucleic acid testing as required! This is not only responsible for personal health, but also the need to prevent others from being infected.

At present, the incubation period of Covid-19 is usually 2-4 days, the shortest may be 1 day, or even less than 1 day, and the longest may be 8 days. Therefore, the management policy for close contacts is "5+3" (5 days of centralized isolation and 3 days of home observation) to minimize risks.

The high-risk area is managed by this scientific law, and it will be reduced to a low-risk area after 5 days without sunshine. But this does not mean that there is no risk, and we must continue to observe. If there is mobility, contact, activity and aggregation in the high-risk area, it will cause new infections. If there is a new positive test, the time will be recalculated.

Therefore, lifting the high-risk area does not mean unsealing, but also strengthening observation. In particular, the current epidemic situation in the central city is still severe and complicated, and it is still the coordinated prevention and control of the central city and the implementation of social control.

Here, Xiaobian asks everyone to understand, support and cooperate with various prevention and control measures as always, especially for nucleic acid testing-

Dear friends, don’t give up and refuse the nucleic acid you should do. Only by doing a thorough examination can you find the infected person as soon as possible, block the transmission chain, win a complete victory in the annihilation war as soon as possible, and return to the fireworks of this city as soon as possible.

    Xinhua Online Haihai, July 23rd (Reporter Xu Xiaoqing) Recently, Shanghai Institute of Printing Technology officially released a long-term "boudoir-raised" non-legacy handmade font-"Yinyan Song Qi".

    Shanghai is the birthplace of modern news and publishing industry in China, which witnessed and promoted the development and evolution of modern Chinese character printing technology. "Chinese character printing and font writing skills" is an intangible cultural heritage in Shanghai, and its protection unit is Shanghai Institute of Printing Technology.

    In 1950s and 1960s, Shanghai Institute of Printing Technology explored the "printing font reform" according to the requirements of relevant authorities, and based on Shanghai’s printing and publishing industry, it collected talents in the fields of fine arts, calligraphy and sculpture from all over the country, and established the font research room of Shanghai Institute of Printing Technology. Today, people widely use computers to input Chinese fonts "Song, Black, Kai, Imitation Song", and the source of font design is this research room. For decades, through inheritance and innovation, the style of Song-style characters has evolved from the initial "Song-style integration" to "Song-style seven-style".

    The font "Yinyan Song Qi" released this time was designed by Xu Xuecheng, the first generation inheritor of the late "Chinese Character Printing Font Writing Technique". In 2020, under the leadership of Chen Qirui, the second generation inheritor of this technique, the value of this font manuscript was rediscovered. Shanghai Institute of Printing Technology started the development project of "Seven Styles of Song Dynasty", led by the fourth generation inheritors, and carried out digital development on the basis of full respect for the manuscript.

    The relevant person in charge of Shanghai Institute of Printing Technology said that the promotion of "Printing and Researching Song Seven" focuses on digital application, which will help to further inherit the intangible heritage of the printing industry and let more people know the evolution of modern Chinese printing fonts. This is also a respect and awe for traditional culture.

On April 10th, Google launched a series of practical barrier-free functions to help people with disabilities use Android phones, including text-to-speech functions, on-demand reading, subtitles and other functions. According to XDA, today Google launched a new function in its TalkBack service: a virtual Braille keyboard, which enables visually impaired people to type on their mobile phones without additional hardware (and without listening to Talkback voice prompts).

Google said that they have worked with Braille developers and users to develop this virtual keyboard, which will be familiar to anyone who has entered Braille before.

The keyboard adopts a 6-key layout, and each key represents one of the 6 Braille dots to form any letter or symbol. For example, typing "A" requires pressing point 1, while typing "B" requires pressing points 1 and 2 at the same time. Users can also use the keyboard to delete letters and words, add lines and submit text.

IT House understands that the new Braille keyboard will be integrated into the Talkback service as part of the "Android Accessibility Kit". . This feature is applicable to all applications, supports Braille Level 1 and Level 2, and is currently only available in English. It should be noted that the Talkback gesture is not available when the Braille keyboard is turned on.

　　In April 2018, Dong Mingzhu mentioned in an interview.Shi Zeng responded domineering: "He (referring to Midea Group) is not an opponent at all. If I regard him as my opponent, I feel very sad." "I am the world’s boss in the field of air conditioning. Who is he?"

　　However, in just a few years,From "despising beauty" to "not catching up with beauty". According to the report of the first three quarters of 2023, Midea Group achieved sales of 292.38 billion yuan in the first three quarters, while the sales of Gree Electric in the same period was only 155.8 billion yuan, and the revenue of Midea Group exceeded that of Gree Electric by 136.58 billion yuan. From the perspective of profit, Gree Electric’s net profit opened a gap with Midea Group after 2019.

　　Then, why did Gree Electric fall far behind Midea Group in terms of revenue scale and net profit scale in just a few years? Is there a problem with Gree Electric’s corporate strategy and internal management?

　　Many strategic misjudgments have widened the gap between Gree Electric and Midea Group’s revenue and net profit.

　　By comparing the revenue scales of Gree Electric and Midea Group in recent years, we can also see that 2019 is a watershed between them. From the perspective of revenue, the revenue growth rate of Midea Group surpassed that of Gree Electric in 2019, and continues to increase. In addition to the HVAC business, the rapid growth of Midea Group’s revenue is mainly based on the rapid recovery of its small household appliances business after the epidemic.

　　From the perspective of net profit, Gree Electric’s net profit growth rate has been surpassed by Midea Group since 2018, and the net profit has been surpassed by Midea Group in 2019, and the gap has widened after the epidemic.

　　Gree Electric’s recovery after the epidemic is relatively weak. In terms of total revenue, the total revenue from January to September 2023 was basically the same as that in 2019 before the epidemic, but the net profit was not as good as that in 2019.

　　Going deep into the income statement, the sales expenses and management expenses of Gree Electric in the first three quarters of 2023 were 13.28 billion and 4.78 billion respectively, up by about 59% and 20% year-on-year.

　　Gree Electric mentioned in the company’s semi-annual report in 2023 that the reason for the increase in sales expenses was "the increase in product installation and maintenance fees". The author thinks that the cost increase is mainly due to the over-concentration of Gree Electric’s main business, and the air-conditioning industry accounts for about 70% of the company’s main business for a long time, lacking product diversity. Compared with Gree Electric, Midea Group’s business is obviously more diversified. In recent years, Midea Group’s continuous efforts in consumer electronics business have made the company’s revenue resilient and wide-ranging.

　　By analyzing the company’s strategy, the author thinks that the following three events may make Gree Electric be surpassed by Midea Group during the epidemic period and continue to widen the distance.

　　First, in 2012, Zhu Jianghong retired, Dong Mingzhu took over from Gree Electric, while He Xiangjian, the founder of Midea Group, retired and Fang Hongbo (Jin Qilin analyst) took over. The two sides chose different strategic paths at this critical moment. Midea group actively embraced the second curve and increased investment in new product research and development; Gree Electric, on the other hand, under the leadership of Dong Mingzhu, focused on the main business of air conditioning, and his business diversification was a little late.

　　Secondly, Midea Group complied with the trend of China’s business transformation, from scale economy to quality economy, and implemented supply-side reform and "efficiency-driven" strategy. Through the reconstruction of T+3 mode, agile operation and flexible manufacturing can be realized. Gree Electric, on the other hand, insists on the traditional mode of "pressing goods, rebate and fixing sales by production", which leads to rising costs and declining efficiency.

　　Finally, in the face of the rise of e-commerce, Midea actively implements the "two-wheel drive" strategy, which not only improves the efficiency of traditional channels, but also innovates the marketing model to conform to the development of e-commerce. However, Gree Electric’s e-commerce channel was slow and relatively negative in the early stage, which led to the online market share being surpassed by Midea Group.

　　It is noteworthy that Gree Electric entered the smart phone market in 2015. In 2017, on the first generation of Gree mobile phones, Dong Mingzhu, the chairman of Gree Electric, put his head on the boot screen of the mobile phone, and every time the user turned on the phone, he could see Dong Mingzhu’s photo with greetings from Dong Mingzhu below.

　　Although Gree Electric has never published its mobile phone sales, according to the sales data of several e-commerce platforms, the total sales volume of Gree mobile phones since its establishment in 2015 is about 40,000-50,000 units. In contrast, in 2023 alone, the total shipments of mobile phones in the domestic market totaled 289 million units.

　　In the smart phone market with many high-tech companies, such as Xiaomi Company, which focuses on cost performance, and Huawei Apple, which focuses on high-end, Gree Electric’s failure in the mobile phone market may have become inevitable.

　　The crumbling air-conditioning business in the post-cycle era of real estate

　　Lack of significant second growth curve support, business is concentrated in air-conditioning business in Gree Electric. At the bottom of the post-cycle of real estate, whether the company’s revenue can maintain the status quo may also be debatable.

　　As a daily electrical appliance purchased by every household, air conditioning benefited from the vigorous development of China’s real estate market in the past, and also ushered in its own prosperity. A number of studies show that, although there is a certain lag, there is a high correlation between the sales volume of air conditioners and the number of new houses delivered.

　　According to the data of the National Bureau of Statistics, in 2023, the national real estate development investment was 11,091.3 billion yuan, down 9.6% from the previous year; Among them, residential investment was 8,382 billion yuan, down 9.3%. From the real estate market pain caused by aging and economic transformation, the author will put a question mark on the sustainable growth of Gree Electric’s revenue.

　　CCTV News:On the afternoon of December 13th, the State Council Joint Defense and Control Mechanism held a press conference. A reporter asked, some elderly people wanted to be vaccinated before, but they were assessed as inconsistent due to basic diseases and other reasons. Does this mean that they have not been vaccinated against COVID-19?

　　Wang Huaqing, chief expert of immunization program of China CDC, responded that if there is a serious allergic reaction after vaccination, this kind of vaccine can’t be vaccinated again in the future, and most other situations belong to a slow vaccination scenario. In the early stage, because of the basic diseases, we assessed that it was impossible to vaccinate, and most of this situation belonged to delayed inoculation.

　　He said that if this elderly person has a basic disease, he is in the early stage of attack, he is in a stable stage after a period of treatment, or he can’t be vaccinated because of special treatment. When the special treatment is over, these people can consider vaccination, especially in the current situation where the epidemic intensity is relatively large and there are many sources of infection, these people can be vaccinated again after re-evaluation and permission. The elderly should be well protected before they are vaccinated, and this kind of protection is also needed in the later period. If he enters the stable period of the disease and after the special treatment, it is recommended to vaccinate as soon as possible if he meets the conditions.

　　Guangming net news Since the beginning of this year, large language models such as ChatGPT and ERNIE Bot have been popular, and the question of whether artificial intelligence (AI) can surpass human beings has aroused heated discussion. On May 29th, the "2023 China Computing Power Development Seminar" organized by China Intelligent Computing Industry Alliance was held in the Institute of Computing Technology, Chinese Academy of Sciences. The theme of this seminar is the opportunities and challenges of computing power under ChatGPT, which brings together many authoritative experts and scholars in the industry to conduct in-depth exchanges and discussions from multiple dimensions such as technology and ecology, determine the development trend of the liquidation power industry, and give countermeasures for the current artificial intelligence infrastructure and computing power service construction.

　　At the seminar, Chen Runsheng, an academician of China Academy of Sciences, said that the development of artificial intelligence is unstoppable by human beings, which is the essence of scientific development. At the same time, he pointed out that the phenomena of "Breakthrough" and "Grokking" in the big language model deserve our consideration.

　　What is "emergence"? A complex system is made up of many tiny individuals, who come together and interact with each other. When the number is large enough, it shows a special phenomenon that can’t be explained by micro-individuals, which is called "emergence". Chen Runsheng vividly explained, "I gave it (the big model) a lot of learning data, and as a result, there will be something in its answer that is not in the learning data. This phenomenon is called emergence." The calculation of a large model shows that when the training data is large (for example, more than 100 billion), there will be an emergence phenomenon, and this phenomenon will not occur when the scale is small.

　　What needs to be clear is that the emerging phenomenon is controversial in the scientific community at present. For example, a professor at Stanford University thinks this is a metric problem, which involves measurement, basic physical coordinate system and so on.

　　"Emergence in the process of natural language processing due to the rapid increase of the whole computation is a new problem, which is worth considering," Chen Runsheng said.

　　What is an epiphany? Chen Runsheng explained, "In the process of training a neural network, you don’t understand it once, twice, the fourth time, and the fifth time. Just like a child learning something, you don’t understand it once or twice, and you suddenly learn it after teaching N+1 times."

　　He believes that this is a model of human brain learning, "learning to understand at a certain time", "computers can’t have epiphany, but large models will have epiphany."

　　Not long ago, Claude, one of ChatGPT’s main competitors, expanded the number of tokens in the context window to 100,000, equivalent to 75,000 words, which greatly exceeded the 8192 tokens in the context window of GPT-4. This means that users can upload up to 500 pages of documents to Claude, which can understand and digest the information in less than 1 minute and answer users’ questions based on the uploaded information.

　　Claude was launched by Anthropic, a company founded by former OpenAI employees. Since the end of 2022, Google has invested nearly $400 million in the company.

　　In this regard, Chen Runsheng believes that the current learning speed of large models is much faster than we thought. "These two companies (OpenAI and Anthropic) are catching up with each other. Maybe after a while, GPT-5 will be stronger than Claude, and it will develop so fast that people will not catch up in the future."

　　"What’s more troublesome is that these big model companies are considering manipulating third-party equipment," Chen Runsheng said. "Being able to manipulate third-party equipment is a worrying thing. If you manipulate things related to safety and national defense, it will be terrible."

　　Chen Runsheng admits that the structure of human neural network is much more complicated than the current big model, and the development of artificial intelligence still has a long way to go. "The current (artificial intelligence) neural network should have revolutionary changes in the spatial structure model. Maybe at that time, (AI) can really surpass human intelligence."

Remember the flu "shock wave" this spring? The resurgence of influenza A (H1N1) subtype caused the school to suspend classes in a large area, and the children who had returned to school were returned home because of the flu. However, the affected children have suffered a lot, and symptoms such as headache, high fever and cough are indispensable, and parents are also worried.

As the weather gets colder and the seasons change alternately, the influenza virus becomes active. Prevent the flu, get vaccinated, now!

What is the flu?

Influenza, referred to as "flu" for short, is usually an acute respiratory infectious disease caused by influenza A or B virus. It is highly contagious and people are generally susceptible. The main manifestations are acute onset, severe systemic symptoms, sudden chills, fever, headache, systemic aches, stuffy nose, runny nose, dry cough, chest pain and other symptoms. Unlike the common cold, influenza is prone to pneumonia. In severe cases, acute respiratory distress syndrome and septicemia may occur, and if not treated in time, it may even lead to death.
