Light up teenagers’ scientific dreams

  This year’s government work report proposes to thoroughly implement the strategy of rejuvenating the country through science and education and strengthen the basic support for high-quality development.

  Science education has also become one of the hot topics of deputies at the two sessions of the National People’s Congress this year. How to better promote science education and teach the first lesson of science education? Let’s listen to the deputies.

  Stimulate interest in learning and cultivate scientific spirit.

  In recent years, science education has been incorporated into all stages of basic education, and the Ministry of Education and other departments have introduced a series of measures to promote science education to take root. Primary and secondary schools around the country have explored various ways to promote science education to blossom and bear fruit. Science education has become a powerful starting point for cultivating students’ scientific spirit.

  "Science education can not only help students to establish a correct world outlook, outlook on life and values, but also cultivate their innovative spirit and practical ability. It can also sow scientific seeds, stimulate young people’s curiosity and imagination, and cultivate young people who have the potential of scientists and are willing to devote themselves to scientific research." Deputy Zhang Yanqiu, vice president of the second primary school in Dachang Hui Autonomous County, Langfang City, Hebei Province, said so.

  In the view of representative Zhang Yanqiu, the importance of science education has become a social consensus, and some achievements have been made, but there are still some problems that need to be solved urgently in actual teaching. "Some primary and secondary schools are difficult to provide high-quality science education due to the limitations of teachers and equipment. At the same time, some contents of science textbooks have lagged behind the development of science and technology, and some teachers’ teaching methods are traditional, lacking innovation and interaction, which makes it difficult to stimulate students’ interest in learning. "

  Member liu ling, President of China Private Education Association, has long been concerned about the reform and development of science education. In his investigation, he found that the top-level design of science education in primary and secondary schools is not fine enough, and the leading role of planning needs to be further strengthened; The development of science education resources is not enough, and the system and mechanism of social forces participating in science education need to be further improved.

  "The software and hardware construction of science education needs to be continuously improved." Member Gao Jinfeng, president of Jiangyan Experimental Primary School Education Group in Taizhou City, Jiangsu Province, said that at present, the proportion of science laboratories and experimental resources in primary and secondary schools is insufficient, the imbalance between urban and rural areas and regions is obvious, and the lack of experimenters has greatly reduced the experimental effect of students. At the same time, the full-time rate, professional rate and counterpart rate of science teachers are low, the stability of part-time teachers is poor, and teachers are not willing to take the initiative to teach.

  Add more science and technology interest groups and innovation laboratories.

  How to teach the first lesson of science education well and sow the seeds of science in students’ hearts?

  "Planning first." Committee member liu ling pointed out that the relevant state departments can formulate special plans for the development of science education, and incorporate them into the planning outline for building a strong country through education, so as to give full play to the leading role of top-level design.

  Member Gao Jinfeng said that the allocation of science education resources should be included in the government supervision project to supervise the allocation of science education resources in primary schools in various provinces and cities.

  "Diversified actions and cooperation inside and outside the school" is the key point pointed out by member Ni Minjing, curator of Shanghai Science and Technology Museum. Member Ni Minjing pointed out that the school should set up more scientific and technological interest groups and innovative laboratories, and try to use various emerging teaching technologies and methods. At the same time, the science curriculum in school should emphasize knowledge, systematicness and foundation to form students’ basic thinking ability; Off-campus courses should pay more attention to practicality, modernity and diversity in order to cultivate students’ personality and specialty. It is suggested that primary and secondary school students should go out of the campus every week to investigate and practice in social classrooms, and encourage the society to carry out various scientific and technological practical activities and competitions.

  Improve software and hardware to avoid "doing experiments on the blackboard"

  Stimulate teenagers’ curiosity and imagination, and strengthen the teaching material system of science education courses and the construction of teachers.

  Deputy Zhang Yanqiu suggested further improving the curriculum textbook system and strengthening the revision and improvement of curriculum standards and textbooks to adapt to the development trend of science and technology and increase students’ knowledge reserves. Increase investment in science education, improve the level of teachers, update experimental equipment, and provide good hardware conditions for science education.

  "Based on the new goals and requirements, we will revise the textbooks for science education in primary and secondary schools, innovate the curriculum system, and urge all local schools to implement the experimental training conditions for textbooks and courses to avoid’ doing experiments on the blackboard’." Commissioner liu ling said.

  Committee member Ni Minjing agreed with this: "It is impossible to cultivate real science and technology innovation ability only by listening, watching and speaking. It is necessary to further increase investment in experimental teaching and change the scientific education mode focusing on telling stories, watching experiments and doing exercises."

  Commissioner Gao Jinfeng focused her attention on the construction of the teaching staff. She said that it is crucial to build a team of science teachers who "love, adapt and enjoy teaching". "At this stage, we can enrich and optimize the team of science teachers by means of’ on-campus job transfer, regional training and off-campus crowdfunding’. Establish an initial vocational allowance for science teachers and a’ continuous teaching award’ for part-time teachers to enhance the professional identity of full-time and part-time science teachers and encourage them to continue to engage in science education. When conditions are ripe, it is suggested that experimenters be included in the teacher title promotion system. " (Reporter Jin Haotian Zhang Xiaohua)

Focusing on Drug Targets: "Fighting poison with poison" —— The latest research progress of oncolytic virus

Since the 19th century, virus therapy for cancer has been studied. However, due to technical barriers and safety problems in genetic engineering, great progress has not been made until the last 20 years. At present, viralvectors for gene therapy and oncolytic viruses (OVs) are the main methods used by viruses as tumor therapy. The main difference between gene therapy virus vector and OVs is that the virus used in gene therapy virus vector is a non-replicating virus, while the vector used in OVs is a virus with replication ability.

93461653176982951

OVs refers to a kind of viruses that can selectively infect and kill tumor cells without damaging normal cells, and they often have good tumor lysis and targeting. OVs can replicate in the host cell after infecting tumor cells, and the released progeny viruses can continue to infect surrounding tumor cells, at the same time activate local or systemic anti-tumor immune effects, change tumor microenvironment and further improve anti-tumor effects. Natural oncolytic virus has some limitations, such as inconsistent safety or weak ability to stimulate the body to produce tumor immunity. In order to overcome the above shortcomings, oncolytic virus vector came into being: it not only retains the ability of oncolytic virus to kill tumor cells, but also enhances its efficacy of activating immune response after genetic modification.

54211653176983336

From non-gene editing type to gene editing type, OVs contains many kinds and characteristics. According to the different nucleotide types of virus genome, OVs vectors can be divided into DNA virus vectors and RNA virus vectors. Among them, the main DNA viruses are herpes simplex virus (HSV), adenovirus (AdV), vaccinia virus (VV) and H1(parvovirus H1. RNA viruses are mainly reovirus (RV), coxsackie virus (CV), poliovirus (PV), measles virus (MV), NDV and vesicular stomatitis virus (VSV).

11771653176983446

The latest research progress

1. At present, five products have been approved for listing in the world, and it is predicted that they will reach the market of over 10 billion dollars in the future.

64651653176983953

2. According to the data of Toubao Research Institute, the market size of oncolytic drugs in China will continue to grow at a compound annual growth rate of 16.2%, and it is expected to rise to 1.43 billion yuan by 2024.

55051653176984020

3. According to the number of research targets, they are IL-12, GM-CSF, PD1, IL-15, PDL1, CD, CD19, CTLA4, NIS, etc.

85001653176984102

4. In the research enterprises, among them, there are many researches and developments on oncolytic viruses, such as Icell Kealex Therapeutics(10), Cell Genesys(7), Virogen Biotechnology (6), PsiOxusTherapeutics(5), Transgene(5) and Jennerex(4). In addition, domestic enterprises such as Innomicro, Synbiotics, Shanghai Medicine, Ruotai Medicine, Kangwanda Medicine, Saibainuo, Lepu Bio, Tasly, and Funuojian are also deployed in this field.

5. Statistics of drugs currently in clinical research stage are as follows:

Introduction of key drugs

Among the five oncolytic viruses approved worldwide, including picornavirus Rigvir, which is approved for the treatment of melanoma in Latvia; Secondly, today’s reborn (recombinant human P53 adenovirus injection) and recombinant human adenovirus type 5, which were approved in 2004 and 2005 respectively, were approved for the treatment of solid tumors such as hepatocellular carcinoma, nasopharyngeal carcinoma and pancreatic cancer. In 2015, the United States and Europe approved the engineered herpes simplex virus (HSV-1) of talimogene laherparepvec(T-VEC) for the treatment of unresectable metastatic melanoma. Finally, in 2021, Japan approved the improved herpes simplex virus teserpaturev for the treatment of brain cancers such as glioblastoma. The statistic of some drugs in that lead stage of clinical development are as follows:

1、CG0070

CG0070 is a genetically modified adenovirus type 5 (Ad5), which contains cancer selective promoter E2F-1 and immune cell stimulating factor GM-CSF gene, and selectively replicates and lyses tumor cells in Rb-deficient tumor cells. The rupture of cancer cells will release tumor-derived antigen and GM-CSF expressed with the virus, thus stimulating systemic anti-tumor immune response. CG0070 was introduced by Lepu Bio from CG Oncology in the United States, and obtained its product development rights and global supply rights in China; Except China, the rights and interests in Japan, South Korea, China, Taiwan Province and other Asian countries were acquired by Kissei Pharmaceutical.

36331653176984638

2、Pelareorep

Pelareorep(AN1004) is a non-pathogenic reovirus introduced by Oncologics Biotechnology by Arnold Pharmaceuticals. It can overcome the neutralizing antibody, selectively infect and destroy tumor cells by activating the body’s own immune system, and is used to treat various solid tumors and hematological malignancies. Pelareorep is a rapidly developed oncolytic virus product that can be administered by intravenous injection in the world. The second phase clinical trial of Pelareorep in the treatment of metastatic breast cancer found that the overall survival rate of patients with ER+PR+/HER2- breast cancer was doubled (21.8 months vs. 10.8 months). In its global phase II clinical trial (BERIL-1) for the treatment of head and neck squamous cell carcinoma (HNSCC), the median survival time of patients was as high as 10.4 months. In March, 2022, Oncologics Biotechnology announced that it had completed the safety assessment of three patients in the metastatic colorectal cancer (mCRC) cohort of the oncolytic virus Pelareorep phase 1/2 GOBLET study.

46101653176984720

3、pexastimogene devacirepvec

Pexastimogen devacirepvec (JX-594) is a genetically engineered vaccinia virus introduced from abroad by Lee’s Pharmaceutical Factory. Its TK gene is mutated, and human GM-CSF gene is inserted to enhance the anti-tumor immune response. The advantages of using vaccinia virus include the stability of intravenous infusion, strong cytotoxicity and the safety of classical live vaccine. Previously, the drug had poor clinical performance in phase III of hepatocellular carcinoma, and the efficacy of the drug in combination with cemiplimab in the treatment of renal cell carcinoma is currently being evaluated.

85231653176985280

4. Naomi Loki

Loki (GL-ONC1, Olvi-Vec) was developed by Genelux Company, and Hengyi Bio owns its development rights in Chinese mainland. It is an oncolytic vaccinia virus. Three expression cassettes encoding β-galactosidase, β-glucuronidase and renin luciferase/green fluorescence (RLuc-GFP) fusion proteins are used to replace virus TK, hemagglutinin and F145L genes respectively. A phase I clinical trial of GL-ONC1 in patients with head and neck cancer showed that intravenous injection of GL-ONC1 combined with standard chemotherapy could improve the overall survival rate. This study also proved the safety of the virus.

34871653176985361

5、OH2

OH2(BS001) is the first candidate drug for oncolytic virus in the world, which is independently developed by Binhui Ib/II-tech, and has chosen HSV2-2 as the carrier and entered clinical trials. Clinical data show that the objective remission rate (ORR), disease control rate (DCR) and one-year survival rate (OS) of BS001 are 30%, 50% and 50%, respectively. In addition, the latest clinical data in the treatment of colorectal cancer show that the objective remission rate of BS001 injection in the treatment of colorectal cancer patients has exceeded 10%. The objective remission rate of BS001 injection combined with PD-1 monoclonal antibody was 18.2%.

57311653176985414

prospect

In recent years, with the development of genetic engineering technology, people have a deeper understanding of the function and structure of virus genes. Optimizing the design and operation of virus genome to produce non-pathogenic viruses has become the research direction of oncolytic viruses, which has greatly promoted the progress of oncolytic virus therapy. Combined treatment of oncolytic virus with chemotherapy or immunotherapy drugs, or even combined application of multiple oncolytic virus drugs, may control tumor progression or cure tumor more effectively, and provide potential clinical treatment options for tumor patients. We believe that with the deepening of oncolytic virus research, oncolytic virus therapy will play a wider and deeper role in treating human diseases.

Beijing urban management changes new uniforms, and each player has a number on his chest.

  Since yesterday (October 1st), the city’s urban management team members in Beijing have started to carry out law enforcement inspections with new uniforms. Recently, the Municipal Urban Management Law Enforcement Bureau has uniformly renewed the uniforms and signs of law enforcement personnel in the city’s urban management system. On the first day of the Eleventh Golden Week, the city’s environmental order was good. During the festival, all urban management and law enforcement departments will take a break and take up their posts, focusing on strengthening the prevention and control of bustling commercial districts and characteristic blocks, major transportation hubs, large-scale gatherings, activities and other crowded areas.

  After asking the way, the tourist said, Have you changed your uniforms?

  "Have you changed your uniforms?" Yesterday morning, outside the East Palace of the Summer Palace, Mr. Li, who was traveling from Hebei to Beijing, was surprised after asking the urban management team for directions. He said: "I mainly asked the city management for directions in the Bird’s Nest two days ago, and the answer was very detailed. I still have an impression of the previous uniforms."

  Beijing Youth Daily reporters saw in Qianmen and the Summer Palace and other popular National Day attractions that all urban management team members have put on new uniforms and started to perform their duties. The clothing color is navy blue, with a golden logo, and each team member’s number is on the chest.

  According to reports, the new uniforms mainly consider adapting to the fact that urban management law enforcement workplaces are mostly outdoors and on the streets, which is convenient for duty activities. This is also the requirement of the Municipal Urban Management Law Enforcement Bureau to implement the "Administrative Measures for the Supply of Clothing and Signs for Urban Management Law Enforcement" by the Ministry of Housing and Urban-Rural Development, strengthen the construction of urban management law enforcement teams, and further promote standardized and civilized law enforcement.

  Solve the problem of people who are not empty in the three-meal car

  After the flag-raising ceremony yesterday morning, crowds poured into Qianmen area, and the law enforcement team members of Dongcheng Urban Management began to guide the crowd. According to reports, in view of the relatively dense number of tourists watching the flag-raising during the holiday season, Dongcheng City Management has sent six law enforcement teams to strengthen the deployment in Qianmen Arrow Tower, Qianmen East Street and Chang’ an Avenue from 5: 00 every day, and sell tourist goods to the following tourists. Personnel engaged in unlicensed catering will be disposed of promptly and quickly.

  在东城,每天将有300余名队员巡查在全区各个街道和社区,发现各类问题及时解决。在簋街、南锣鼓巷及北京站等重点地区,更是每天32个车组全天连续14小时定人定岗盯守,队员一日三餐均在执法车内解决,确保每个时段岗位不空人。

  节日期间 北京城管全员停休

  为确保今年国庆期间环境秩序良好,节日期间城管执法部门全员停休,全员上岗,实名管控,重点对无照经营、非法运营、非法小广告、占道经营、店外经营、非法停车场等环境秩序问题进行查处,全面遏制重点地区环境秩序类问题。

  黄金周期间,城管执法部门重点加大对天安门及周边地区、长安街沿线,故宫、奥林匹克公园、什刹海、恭王府、八达岭、十三陵及市属11大公园,繁华商业区和特色街区,主要交通枢纽,大型集会、活动等人流密集地区的防控力度。同时对违规户外广告、牌匾标识、夜景照明、山寨指路牌、临窗广告以及车身广告等,及时督促责任人进行拆除、清理、维修或更换,对附带电话号码的,及时进行警示提醒。

  According to the person in charge of the Municipal Urban Management Law Enforcement Bureau, the management of construction sites will continue to be strengthened during the festival, and the construction enclosures in key areas will be checked according to the specifications, and the construction dust will be strictly controlled, and the management of construction waste transportation will continue to be strengthened to prevent road spillage; Increase the control of illegal activities such as open-air barbecue, burning garbage and white pollution. Visit and investigate the gas supply, users, kitchen waste generation and collection and transportation units around the key security areas one by one, and rectify the problems.

  Urban management volunteers help serve tourists.

  In addition, the urban management law enforcement departments, in conjunction with the Beijing Urban Management Volunteers Association, set up publicity service stations for urban management law enforcement in tourist attractions and window areas during the National Day to monitor the environmental order and provide tourists with services such as inquiries, directions and simple medical care.

  Yesterday, in Qianmen Street, Nanluoguxiang Pedestrian Street, Summer Palace and other areas, volunteers organized by urban management departments participated in the publicity of laws and regulations, stopped uncivilized behavior, and provided some services urgently needed by tourists, such as directions.

  The person in charge of the Municipal Urban Management and Law Enforcement Bureau said that mobilizing members of the association, volunteer groups and the general public to actively participate in the maintenance of holiday environmental order, especially guiding social units in key areas to actively participate in environmental governance and rectification, can jointly create a beautiful and clean urban environment.

Attention! This virus has entered a period of high incidence!

recent days

# Guangdong Norovirus enters a high incidence period #

Rushed to the top of the hot search list in Weibo

Many netizens commented.

"vomiting and diarrhea" and "very uncomfortable"

Even "the whole family turns to recruit"

Multi-site disease control department reminded

Acute infectious diarrhea caused by norovirus

Has entered the peak of the disease

Previously, Guangdong CDC had issued prevention guidelines.

Guangdong every October to March of the following year.

It is the peak of norovirus infection outbreak.

Contact transmission and food-borne transmission are the main methods.

Key prevention and control sites

For schools and kindergartens and other collective units.

What are the characteristics of Norovirus?

What are the symptoms after the move?

Come and have a look!

"Cunning" Norovirus

First, strong pathogenic ability

Norovirus is highly infectious, and it can infect many people with only a small amount of virus particles. Therefore, in schools, kindergartens and other places where people gather, it is easy to have a cluster epidemic of norovirus infection.

Second, there are many infection tricks.

Eating can infect: eating food contaminated with norovirus.

Drinking water can infect: drinking water contaminated with norovirus.

Contact/aerosol can infect: contact with the aerosol generated by the patient’s excrement or vomit, or indirectly contact with articles or environment contaminated by vomit or excrement, etc., you may be infected by norovirus.

Third, don’t pick people.

Norovirus is generally susceptible to the whole population, and people of all ages may be infected.

Fourth, the resistance is extremely strong

It can survive in the temperature range of 0~60℃, and ordinary hot water can’t burn Norovirus.

75% alcohol and antibacterial hand gel can’t inactivate norovirus.

It can survive on the surface of objects for 2 weeks and in water for more than 2 months.

Common symptoms after infection

The incubation period of norovirus infection is 12 to 72 hours, usually 24 to 48 hours. Norovirus infection is generally mild, the most common symptoms are vomiting and diarrhea, followed by nausea, abdominal pain, headache, fever, chills and muscle aches. Children are mainly vomiting, while adults are mostly diarrhea.

How to treat norovirus gastroenteritis?

Norovirus is a self-limiting disease, and there is no effective antiviral drug at present. Most patients can recover in 2~3 days after onset, and they can take oral sugar saline or oral rehydration salt to supplement the water consumed by vomiting and diarrhea. A small number of infants and the elderly, especially those with basic diseases, may cause more serious symptoms such as dehydration and slow recovery, so they should be treated in time.

Tips for family prevention

Read a picture

besides

Nursery institutions and schools

Attention should also be paid to preventing norovirus infection.

Nursery institutions and schools

How to prevent norovirus infection?

First, timely detection and standardized management of cases

Nursery institutions and schools should do a good job in student health management, and strictly implement morning (noon) check-ups and registration of absenteeism due to illness. Once patients with vomiting, diarrhea and other symptoms are found, they should seek medical treatment in time and be isolated and managed. Report to the disease control institutions and relevant administrative departments immediately when the abnormal increase of cases is found.

Second, strengthen the management of drinking water and food hygiene

Provide safe drinking water, do a good job in drinking water management, investigate the damage and leakage of drinking water supply network, regularly clean and disinfect secondary water supply facilities, and do a good job in drinking water quality testing to ensure water supply safety. Do a good job in the supervision of food raw materials and processing links, pay attention to the separation of raw and cooked, and thoroughly cook and cook.

Three, strengthen the health management of kitchen workers, nurses and other employees.

Nursery institutions and schools monitor the health status of kitchen workers and nurses, and when there are symptoms related to intestinal infectious diseases such as diarrhea, vomiting and nausea, they should immediately suspend their work, seek medical treatment in time, and prevent them from going to work despite illness. Wear a mask and do good hand hygiene during food preparation and catering.

Fourth, do a good job in environmental cleaning and disinfection

Regularly clean and ventilate public places in campus/park (such as classrooms, dormitories, canteens, libraries, bathrooms, etc.), and regularly clean and disinfect key parts (such as door handles, stair handrails, faucets, toilet buttons, elevator buttons, handrails for getting on and off the bed, etc.).

Five, scientific and standardized treatment of vomit

The vomitus and feces found in the case should be handled by the trained personnel in accordance with the relevant operating guidelines. Focus on the disinfection of the surface of environmental objects, daily necessities, food processing tools, drinking water, etc. polluted by vomit and feces.
