　　The weather turned cold.

　　An accident of carbon monoxide poisoning

　　More.

　　Reporter from Fujian Hospital of Shanghai Children’s Medical Center

　　(Fujian Children’s Hospital) was informed that

　　Department of Critical Care Medicine, Fujian Children’s Hospital

　　Recently, three people who used gas water heaters to take a bath were admitted.

　　Children suffering from carbon monoxide poisoning and falling into coma

　　One of the girls is 10 years old.

　　The other two girls are sisters.

　　They are 9 years old and 5 years old respectively.

　　The medical staff in the Department of Critical Care Medicine transported the children from the outer hospital to the department with rescue equipment such as ventilator.

　　Heartbeat recovery after rescue

　　But there is still no spontaneous breathing.

　　The poisoned 10-year-old girl lives in a rented house with her family. A few days ago, when she used a gas water heater to take a bath, the gas leaked, and the bathroom space was narrow and the ventilation was not smooth. She was poisoned by carbon monoxide. When her family found out, she was already unconscious, unable to respond, and her heartbeat and breathing were gone.

　　Parents quickly took her to the provincial children’s hospital. After intensive rescue by medical staff, the girl’s heartbeat was restored. However, due to the long time of ischemia and hypoxia, it is difficult to recover from brain damage. At present, she still has no spontaneous breathing and is in a deep coma.

　　The Department of Critical Care Medicine of Provincial Children’s Hospital used mild hypothermia therapy and bedside EEG monitoring equipment to treat children with carbon monoxide poisoning.

　　On the second day of the girl’s hospitalization, the Department of Critical Care Medicine of the hospital admitted a pair of little sisters who also suffered from carbon monoxide poisoning while taking a bath with a gas water heater.

　　Due to the timely detection, their condition is relatively mild, but they still have nervous system injuries such as memory loss and weakness of both lower limbs, and are currently receiving hyperbaric oxygen treatment.

　　"Carbon monoxide is tasteless, colorless and non-irritating, which will lead to hypoxia in human cells, tissues and organs. The poisoned person may only feel a slight headache at first, and the symptoms will become more and more serious as time goes by. " Wang Shibiao, chief physician of the Department of Critical Care Medicine, Fujian Children’s Hospital, said that in clinical practice, many poisoned people were found to have severe asphyxia, cardiac arrest and respiratory arrest, and even if the rescue was successful, there were serious sequelae of the nervous system.

　　The Department of Critical Care Medicine of Provincial Children’s Hospital used mild hypothermia therapy and bedside EEG monitoring equipment to treat children with carbon monoxide poisoning.

　　These places often happen.

　　Carbon monoxide poisoning incident

　　Wang Shizhen reminded:

　　Kitchen with poor ventilation using gas, toilet with improper installation of gas water heater, car compartment with air conditioner closed, and room with poor ventilation burning coal are often places where carbon monoxide poisoning incidents occur.

　　There are also some people who burn charcoal to cook tea or eat charcoal hot pot in a warm indoor stove, which are prone to carbon monoxide poisoning.

　　In daily life

　　How to avoid carbon monoxide poisoning?

　　Deputy Chief Physician Colin Min, Intensive Care Unit of Provincial Children’s Hospital, suggested:

　　Try not to install the gas water heater in the bathroom, but should be installed outside the bathroom near the window. If it is installed indoors, don’t close the window when bathing.

　　When using coal hot pot and charcoal hot pot for family dinner, pay attention to keep indoor ventilation, or open the door and open the window at the right time.

　　When using pipeline gas or liquefied gas tanks, it is necessary to prevent pipeline aging and gas leakage, and the gas valve should be tightened.

　　If gas is used at home, it is recommended to install a carbon monoxide detector and check and maintain it regularly.

　　Don’t sleep in a car with closed doors and windows and air conditioning. When driving for a long distance, you can open the internal circulation and open the window regularly for ventilation.

　　If carbon monoxide poisoning occurs

　　Windows should be opened immediately for ventilation to make air convection.

　　Quickly close the gas cooker, gas water heater valve, etc.

　　Let the poisoned person leave the toxic environment immediately.

　　Move to a place with fresh air and good ventilation.

　　Untie the collar button of the poisoned person’s clothes

　　Keep the respiratory tract unobstructed.

　　At the same time, pay attention to keep warm

　　Prevent complications.

　　Let the poisoned person rest quietly.

　　Because activities will increase the consumption of oxygen.

　　If conditions permit.

　　Patients should be given oxygen as soon as possible.

　　For moderate and severe poisoners

　　At the same time of on-site first aid

　　You should call 120 emergency number immediately.

　　Xinhua News Agency, Beijing, July 16th Question: Authorities responded to the five major concerns of the latest COVID-19 prevention and control plan

　　Xinhua News Agency reporter Dong Ruifeng and Xu Penghang

　　Since the novel coronavirus Prevention and Control Plan (Ninth Edition) was released recently, the monitoring of epidemic situation, the isolation management of risk personnel, and the demarcation standards of medium and high risk areas have been adjusted to further improve the scientificity and accuracy of epidemic prevention and control.

　　What is the basis for the revision of the prevention and control plan? What changes have been made in the division of different risk areas? Does the latest mutant affect the existing prevention and control measures? In response to social concerns, authoritative experts on joint prevention and control mechanism in the State Council made an interpretation and response when interviewed by Xinhua News Agency.

　　Why revise the prevention and control plan? More scientific and accurate

　　Liu Qing, director of the Infectious Disease Prevention and Control Division of the CDC of the National Health and Wellness Commission, said that there are three considerations for revising the prevention and control plan:

　　The first is the change of epidemic situation. The epidemic situation in COVID-19 is still prevalent all over the world. Since the beginning of this year, the frequency of local epidemics in China has increased significantly, and the epidemic has spread to a wide area. The pressure of preventing imports from abroad and internal defense from rebounding has been increasing, and the prevention and control situation has become more severe and complicated.

　　The second is the characteristics of virus variation. As a dominant epidemic strain, Omicron has shorter incubation period, stronger transmission ability and concealment, and faster transmission speed, which brings new challenges to epidemic prevention and control.

　　The third is the results of previous pilot work and the practice of epidemic prevention and control. From April to May this year, the Comprehensive Group of Joint Prevention and Control Mechanism of the State Council carried out a four-week pilot study on the optimization of epidemic prevention and control measures in seven entry cities, including Dalian, Suzhou, Ningbo, Xiamen, Qingdao, Guangzhou and Chengdu. At the same time, it fully absorbed and learned from the practice of prevention and control work and the experience of epidemic disposal in various places.

　　On July 8th, volunteers (first from right) registered the information of nucleic acid testing for Zitingyuan community residents in Qujiang New District of Xi ‘an. Xinhua News Agency reporter Zhang Bowen photo

　　"The ninth edition of the prevention and control plan is an optimization of prevention and control measures, and it is by no means relaxing prevention and control." Liu Qing said that the key is to control the key points under control, put the implementation in place, and resolutely cancel the cancellation, so as to further improve the scientificity and accuracy of epidemic prevention and control.

　　Why adjust the isolation period of risk personnel? Virus incubation period shortened

　　The pilot study on the optimization of epidemic prevention and control measures carried out from April to May found that the average incubation period of Omicron mutant was shortened, mostly from 2 days to 4 days; Most of them can be detected within 7 days.

　　"In order to further improve the scientific and accurate prevention and control measures for the epidemic situation in COVID-19, based on the research results and the prevention and control practices in many places in China, the ninth edition of the prevention and control plan has optimized the time limit and mode of isolation and control of people at risk related to the epidemic situation." Wang Liping, a researcher at the Infectious Diseases Management Office of China CDC, said.

　　Adjust the control time of close contacts and entry personnel isolation from "14 days centralized isolation +7 days home health monitoring" to "7 days centralized isolation +3 days home health monitoring", and adjust the control measures of close contact from "7 days centralized isolation" to "7 days home isolation" … …

　　"This adjustment is to further optimize the prevention and control measures according to the epidemic characteristics of Omicron mutant, which will not increase the risk of epidemic spread and is the embodiment of precise prevention and control." Wang Liping said.

　　When to start the whole nucleic acid test? Clearly define the conditions

　　Regional nucleic acid detection strategies should be different in different scenarios — — The ninth edition of the prevention and control plan further clarifies this. For provincial capital cities, cities with a population of more than 10 million, general cities and rural areas, the regional nucleic acid detection strategies after the outbreak and under the normalization prevention and control were defined respectively.

　　On July 5, a citizen was sampling nucleic acid at a nucleic acid sampling point in Liyuan Street, Binhu District, Wuxi City. Xinhua News Agency reporter Li Boshe

　　Wang Liping introduced that after the outbreak, if the conditions such as "clear source of infection", "clear transmission chain" and "no community transmission" are met through investigation, it is not necessary to carry out all-staff nucleic acid testing in the area where the epidemic occurred, and nucleic acid screening will be focused on the risk areas and people with time and space intersection.

　　If, according to the investigation, the transmission chain is unclear, there are many risk places and risk personnel, and the risk personnel are highly mobile, and there is a risk of spread of the epidemic, it is necessary to start the nucleic acid detection for all the people in the region. The detection range, detection strategy and termination conditions of nucleic acids in different regions are clearly defined in the scheme.

　　How to divide high school low-risk areas? Epidemic-free counties implement normalized prevention and control.

　　According to the ninth edition of the prevention and control plan, high, middle and low risk areas are divided in counties (cities, districts and banners) with epidemic situations. In counties (cities, districts and banners) where there is no epidemic, normalized prevention and control measures are implemented throughout the region.

　　Chang Zhaorui, a researcher at the Infectious Diseases Management Office of China CDC, said that high-risk areas refer to the places where cases and asymptomatic infected people live, as well as areas such as workplaces and activities with frequent activities and high risk of epidemic spread. In principle, they are defined by residential communities or villages, and the scope of risk areas can be judged and adjusted according to the results of epidemiological investigations. In high-risk areas, the measures of "staying at home and on-site service" are adopted. For people in high-risk areas with cross-regional spillover, centralized isolation medical observation was taken for 7 days.

　　Medium-risk areas refer to areas where cases and asymptomatic infected people stay and move for a certain period of time, and may have the risk of epidemic spread, such as workplaces and activities. In the middle risk area, the control measures of "people don’t leave the area and take things at the wrong peak" are adopted. For the personnel in the middle-risk area with cross-regional spillover, take 7-day home isolation medical observation.

　　Low-risk areas refer to other areas in the counties (cities, districts and banners) where middle-high risk areas are located. In low-risk areas, the preventive measures of "personal protection and avoiding gathering" are adopted. People in low-risk areas who go out across regions should leave with a 48-hour negative nucleic acid test certificate. There is no need to take isolation and control measures for people in low-risk areas who go out across regions, but it is required to complete nucleic acid testing twice within 3 days and do a good job in personal health monitoring.

　　Does the latest mutant have an impact? The prevention and control plan is still applicable

　　Recently, Omicron BA.5 subfamily is becoming the main epidemic strain in the world, and it has caused a local clustering epidemic in China. Dong Xiaoping, chief virologist of China CDC, said that compared with other branches of Omikrongya, the overall pathogenicity of BA.5 has not changed significantly, and the ninth edition of the prevention and control plan is still applicable.

　　The ninth edition of the prevention and control plan puts the monitoring of virus in a higher position, embodies the hierarchical nucleic acid screening plan, encrypts the frequency of nucleic acid detection among occupational groups at risk, and adds antigen detection as a supplementary means of epidemic monitoring.

　　"These measures in the ninth edition of the prevention and control plan are effective for the sub-branches of BA.4 and BA.5." Dong Xiaoping said.

　　[Global Network Report] According to CNN and CNBC news, US President Biden issued a statement on the $1.75 trillion "Rebuilding a Better Future" spending bill on the 16th, implicitly acknowledging that the bill will miss the deadline for passing in the Senate before Christmas, and suggesting that the passage of the bill may be postponed until next year.

　　"My team and I are discussing with Senator Manchin, and this work will continue next week," Biden said in a statement, according to CNN. "It will take time to finalize these agreements, prepare legislative changes, and complete all the procedural steps so that the Senate can vote. We will jointly promote this work in the next few days and weeks. Schumer, the leader of the US Senate Majority, and I are both determined to let this bill land as soon as possible. "

　　CNBC said that it was Senate Majority Leader Schumer who set the deadline for Biden’s 1.75 trillion "Rebuilding a Better Future" spending bill before Christmas, but the negotiations are progressing slowly. CNN said that the main obstacle facing the Democratic Party is Senator Manchin, a moderate Democrat, whose "swing vote" is crucial to the passage of the bill.

On the 16th, Biden made a speech at the White House in Washington, USA.

　　Regarding the coverage of this 1.75 trillion bill, it was previously reported that it includes that the United States will invest 555 billion dollars to deal with climate change and develop clean energy, allocate 400 billion dollars to provide two-year free preschool education and reduce the cost of childcare for ordinary families, use 200 billion dollars for childcare tax deduction and income tax deduction for low-income people, and use 150 billion dollars to build housing.

　　Why is this "Rebuilding a Better Future" bill so important to Biden? Washington post analyzed that Biden’s ruling performance and political agenda have been in a state of disaster recently. The chaotic withdrawal of Afghan troops, the resurgence of the COVID-19 epidemic this summer and the rising inflation have made many Democrats worry that the party will face a terrible political situation in next year’s mid-term congressional elections. If the US Congress can pass it, it will prove the ruling ability of Biden and the Democratic Party.

　　Original title: What is the "Mycoplasma Pneumonia" on the hot search? How to treat it?

　　Recently, the incidence of mycoplasma pneumonia in China has increased, especially in southern areas such as Guangdong and Fujian, which has increased significantly compared with the same period last year. On the 12th, "Mycoplasma Pneumonia" boarded a hot search. What is it? How old is the child easy to get? How to treat it?

    Zhao Shunying, deputy director of the National Center for Clinical Research of Respiratory Diseases (Children), explained the related situation of mycoplasma pneumonia.

   What is mycoplasma pneumonia?

    What are the characteristics of mycoplasma pneumonia this year?

    Mycoplasma pneumonia is an acute pulmonary infectious disease caused by Mycoplasma pneumoniae, and it is the most important community-acquired pneumonia for children aged 5 years and above in China. Mycoplasma pneumonia is widespread in the world, and a regional epidemic will occur in about 3 to 7 years. (Community-acquired pneumonia refers to pneumonia acquired outside the hospital, including inflammatory lesions in the lungs within 48 hours after admission. )

    According to experts, mycoplasma is a microorganism, neither a bacterium nor a virus. The pneumonia it causes is completely different from that in Covid-19. Pathogens that cause pneumonia generally have seasonal onset. Mycoplasma pneumonia has been prevalent in some regions of China in recent two years, especially this year, and there are a few families or classes with cluster onset, but it is not an infectious disease and will not be as contagious as COVID-19.

    According to experts, compared with previous years, mycoplasma pneumonia in China has the characteristics of younger age, and some children under 3 years old also have symptoms, so they should see a doctor in time if they have related symptoms.

   How does mycoplasma pneumoniae spread?

    What are the symptoms?

    Mycoplasma infection is mainly transmitted by direct contact and droplets.

    The symptoms of children with mycoplasma infection are similar to most respiratory diseases, with fever and cough as the main symptoms. Generally, the cough is severe, and after the fever has gone down, the cough may continue for 1 to 2 weeks.

    Zhao Shunying, deputy director of the National Center for Clinical Research of Respiratory Diseases (Children), said that this year is the epidemic season of mycoplasma, and children have a fever or cough, especially severe dry cough, which is likely to be infected with mycoplasma.

    Experts especially remind the parents of young children that when mycoplasma pneumonia infection occurs, the child’s fever may not be serious, but there is wheezing or difficulty breathing, or there is a depression in the clavicle. "That is, the child has a hole in the clavicle when inhaling or a stuffy nose when inhaling. Go to the hospital in time."

   How to treat mycoplasma pneumonia?

    How to prevent it every day?

    According to experts, this year, China has formulated guidelines for the diagnosis and treatment of mycoplasma pneumonia in children. In terms of treatment, penicillin and cephalosporins are ineffective in the treatment of mycoplasma pneumonia and need symptomatic medication. Macrolide antibiotics, such as roxithromycin and azithromycin, are currently the first choice for the treatment of mycoplasma pneumonia.

    Once you have a fever accompanied by a severe cough, you should see a doctor in time, find out the cause as soon as possible, standardize the treatment, and avoid using drugs blindly.

    In daily protection, we should pay attention to reducing gathering and keeping good hygiene habits such as washing hands frequently.

    At present, there is no specific vaccine to prevent mycoplasma pneumonia. Expert reminder ↓

    Pay attention to indoor ventilation, try to avoid crowded and poorly ventilated public places, and wear a mask when you must go.

    Cover your mouth and nose with a tissue when coughing or sneezing.

    Maintain hand hygiene, and often wash your hands with soap and hand sanitizer under flowing water.

    Schools, kindergartens and other places should pay attention to ventilation and disinfection to avoid cluster infection.

　　Xue Zhaofeng, a professor at Peking University, has been widely concerned recently because of more than 250,000 subscribers on the paid platform. However, relevant parties in Peking University confirmed to the Beijing Youth Daily reporter yesterday that Xue Zhaofeng is currently leaving his post for personal planning reasons.

　　Yesterday, Peking University confirmed that Mr. Xue Zhaofeng, now working in the National Development Research Institute of Peking University, is going through the process of resignation, which is due to personal planning reasons. Previously, Xue Zhaofeng opened a column on a knowledge payment platform, with over 250,000 subscribers and a total income of nearly 50 million.

　　Xue Zhaofeng was confirmed to leave.

　　According to Peking University, "Teacher Xue’s resignation is a particularly normal personnel flow". As for the reasons for leaving, Peking University said that "this belongs to Teacher Xue’s own personal plan".

　　The reporter of Beiqing Daily saw that Xue Zhaofeng is still in the "teaching staff" of official website, the National Development Research Institute of Peking University. According to the professor’s summary, Xue Zhaofeng is currently a professor of law and economics at the National Development Research Institute of Peking University and co-director of the Research Center of Law and Economics in Peking University. His educational experience includes being a postdoctoral researcher at Northwestern University School of Law and a doctor of economics at George Mason University. In summary, Professor Xue Zhaofeng’s research interests include price theory, law and economics, competition policy and e-commerce regulation and governance. The reporter of Beiqing Daily learned that at present, Xue Zhaofeng is a full-time teacher in Peking University, but he belongs to the employment system. In Peking University, there are not a few employed teachers.

　　Xue Zhaofeng knowledge payment platform subscribers exceed 250,000.

　　Xue Zhaofeng is a veritable "star professor". According to a knowledge payment platform, Professor Xue’s subscription column "Economics Course in Xue Zhaofeng" has more than 250,000 subscribers. The platform claims that this is the column with the largest number of users in the knowledge payment platform and even in the whole market. "It can also be said that users and Mr. Xue have jointly built the largest economics classroom in the world."

　　The reporter of Beiqing Daily saw on the payment platform yesterday that there are currently 250,931 people subscribing to the column "Economics in Xue Zhaofeng", and each person has to pay 199 yuan per year. According to this data, Xue Zhaofeng only earned 49.92 million yuan in this column. Earlier, an insider revealed that the platform was divided into 50-50 shares. According to this calculation, Xue Zhaofeng himself was divided into nearly 25 million.

　　Xue Zhaofeng said in this column, "Since 2010, I have been teaching two courses, Principles of Economics and Legal Economics, in Peking University every year. Now I will teach you the essence of these two courses by subscribing to the column. " In the introduction of the course, it is written that the course is an "audio+graphic" column, which is updated every Monday to Thursday, and the last year (February 20, 2017 to February 19, 2018) has been uninterrupted for 52 weeks. After consumers subscribe to the product at an annual fee, they can read all the contents produced in the column permanently, and there is no refund once the subscription is successful. The course modules of this course include: human nature and scarcity, the profound meaning of cost, the law of demand, the role of price, the structure of the company, etc. Finally, there are related exams.

　　In addition, Xue Zhaofeng has also commented on some hot topics on the Internet, such as "Free is the most expensive", "Raising the train ticket price to solve Spring Festival travel rush", "Online car-hailing platform solves the information asymmetry" and "The risk of Internet finance should be confirmed", which has greatly increased his popularity on the Internet.

　　Celebrity knowledge paid as a sideline?

　　At present, it is also common for some celebrities to open columns on the knowledge payment platform. Take Professor Xue’s platform as an example. At present, many professors and scholars are offering column courses at the same time, including Fu Peirong, head of philosophy department of Taiwan Province University, Wan Weigang, physicist, Wu Jun, computer scientist, Xiang Shuai, doctoral supervisor of finance department of Peking University, Ning Xiangdong, professor of management in Tsinghua University, He Fan, professor of HSBC Business School of Peking University, psychologist Wu Zhihong, etc. Their course prices are all 199 yuan/year, and once they subscribe successfully, they will not be refunded. At present, each of them has gained a large number of "students" by virtue of this platform. For example, Fu Peirong’s Western Philosophy Course has 20,000 subscribers, Wan Weigang’s Elite Day Course has 130,000 subscribers, Wu Jun’s Google Methodology has 60,000 subscribers, Xiang Shuai’s Peking University Finance Course has 120,000 subscribers, Ning Xiangdong’s Tsinghua Management Course has 140,000 subscribers, and He Fan’s.

　　Wan Weigang said in an interview earlier that "the paid column is to provide exclusive services to paying readers. Good research results, in addition to application value, also need to have communication value and enrich the public’s thoughts. " He also said that in order to get a good topic, he consulted a lot of American media information every day. "Sometimes I can’t find anything worth explaining in our column for two or three days." Every day, his column, from topic selection, research and development to writing, takes about seven or eight hours on average, not counting editing and audio recording time.

　　For knowledge payment, some readers think it’s worthwhile. "The economics major chosen in the university was missed by mistake, and now I finally have the opportunity to reread economics, and it’s still in the class of Professor Xue Zhaofeng of Peking University. It’s so cool." However, some readers think it’s a bit expensive. "It’s better to buy two classic economics textbooks to read them yourself for 199 yuan. Their fragmented speeches can’t establish a knowledge system, and many contents can be obtained without spending money, so it’s unnecessary."

　　You can work part-time on the premise of completing your job.

　　In November 2016, the General Offices of the General Office of the Central Committee of the CPC and the State Council issued "Several Opinions on Implementing the Distribution Policy Oriented to Increasing Knowledge Value", which mentioned that "researchers and teachers are allowed to work part-time and pay part-time according to the law". Specifically, researchers are allowed to take part-time jobs to obtain legal income. On the premise of fulfilling their duties and completing their own jobs, scientific researchers may, with the consent of their units, take part-time jobs in enterprises and other scientific research institutions, universities and social organizations and obtain legal remuneration. In principle, the remuneration obtained from part-time jobs belongs to individuals, and a reporting system for income such as equity and dividends obtained from part-time jobs is established.

　　However, it also stipulates that "scientific research institutions and universities should stipulate or agree with scientific researchers on the rights and obligations of part-time jobs, and implement a part-time publicity system for scientific researchers. Part-time jobs must not reveal the technical secrets of their own units, damage or occupy their legitimate rights and interests, and violate their social responsibilities." At present, Peking University has not responded to Professor Xue Zhaofeng’s part-time job on the paid knowledge platform.

　　Ni Shu, a senior science and technology commentator, told the reporter of Beiqing Daily, "The professor’s job is to generate knowledge and spread knowledge. Now it is a good thing that his knowledge has been spread through the cooperation of the platform." He further said that there is a premise that must be stated: he can make money in the market way, and from the way of view, it is the reward he got after he created value for users.

　　Luo Chao, a senior Internet analyst, believes that the essence of knowledge payment platform is sharing economy — — Sharing of knowledge. The greatest charm of the sharing economy lies in the release of individual energy, which not only gives individuals more opportunities to realize cash, but also has the opportunity to gain a broader life. For example, Professor Peking University can expand his "students" several times by entering the knowledge payment platform, and at the same time get considerable economic returns. Of course, not every professor can realize the content on the platform, which is closely related to his field. That is to say, Xue Zhaofeng, a professor at Peking University, is only a case, and not all university teachers can get similar returns through the knowledge payment platform.
