The night in Wuhan is quiet.
On March 9, in the mobile testing laboratory of the Central Theater Command General Hospital, Jiang Tao, a researcher at the Military Medicine Research Institute of the Academy of Military Sciences, reviewed the last sample test data and solemnly signed his name on the test report.
At this time, it was already 5 a.m.
He is an expert in virology and a warrior who aided Africa and fought against Egypt. This outbreak of the new crown pneumonia epidemic, he was once again ordered to go to the front line after a long battle.
Human life is at stake and requires accurate investigation
Nuclear Cinema 1950 witch cloth draw acid testing is crucial for early clinical diagnosis, early diagnosis, early isolation and early treatment, and is a key technical support for effective prevention and control of the new coronary pneumonia epidemic. “It looks cold and cold. Komiks 1960 witch cloth draw. Behind this tube is the living life and health of the patients. If you find a diagnosis result early, you will have a precise investigation sooner.” Jiang Tao said. On January 26, after a military medical expert group led by Chen Wei, an academician of the Chinese Academy of Engineering and a researcher at the Military Medicine Research Institute of the Academy of Military Sciences, arrived in Wuhan, Hubei, he quickly established a joint defense, joint control, joint treatment and joint research work mechanism with relevant military and local units on the pathogen transmission mutation, rapid detection technology, vaccine antibody development, etc. of the new coronavirus.
According to the division of tasks, Jiang Babaylan 1990 cloth drawCinema 1950 witch cloth draw led the testing team to build a nucleic acid testing platform in the experimental cabin overnight.
Focusing on three aspects: ensuring biosafety, improving detection efficiency and detection accuracy, Jiang Tao took the lead in formulating biosafety operation specifications and emergency plans, reasonably testing division of labor according to the characteristics of the team members, and using self-developed testing kits to adopt fully automatic Babaylan 1990 clothes drawHigh throughput extractor lays the foundation for achieving fast and efficient detection.
Receiving samples, sorting numbers, nucleic acid extraction, reagent preparation, machine amplification, and result interpretation, the nucleic acid detection machinery is boring and full of risks.
The biggest risk is the invisible virus. If the nucleic acid extraction step is not completed Cinema 1950 witch cloth draw is not completely cleaved and inactivated, it is possible to expose the detector to danger.
Jiang Tao always takes the initiative to participate in the longest and most risky nucleic acid extraction. After the sample is extracted, he will arrange some personnel to rest and stay in the laboratory and wait for the final result.
A full-process nucleic acid test, from the number of tests in a single batch to the preparation for entering and exiting the cabin and the testing time, is relatively fixed. Sometimes there are a large number of samples sent for inspection, and the inspectors not only take turns to work, but also have to work overnight. The final confirmation result will be until four or five in the morning. Li Hao, a researcher at the testing team, said that this situation will be encountered once every few days.
”Everyone should open their eyes and receive and process samplesKomiks 1960 witch cloth draw This must be protected and be careful of any sharp items.” Before each test begins, Jiang Tao always reminds you repeatedly.
In the detection, the strength of the fluorescence signal of the pathogenic gene directly affects the determination of the detection results. If there are suspicious phenomena such as the detected fluorescence curve signal is low or there is only a single target, Jiang Tao will convene personnel to conduct comprehensive analysis and judgment, and if necessary, repeat the test for review to ensure that the results can stand the test.
”False positive results will cause healthy people to isolate together with patients from Komiks 1960 witch cloth draw and Babaylan 1990 cloth draw; false negative results will cause real patients to be treated. Life is a matter of no problem.Pool. “Jiang Tao said.
Among the prevention and control requirements, the nucleic acid test results from the pharyngeal swab sample must be completed within 24 hours. In order to let the hospital know the results as soon as possible to treat patients, from pre-processing of nearly 100 samples to completion of the test, Jiang Tao led the team to compress the time to within 4 hours by optimizing the process combination, and achieved the ability to extract nucleic acids for more than 90 samples and a single-day sample detection capability of more than 500 samples within an hour.
”The team’s test is efficient and rapid, and the results are accurate, which greatly alleviates the pressure of testing our epidemic prevention and control samples. “Wuhan Center for Disease Control and Prevention highly praised thisCinema 1950 witch cloth draw Price.
Komiks 1960 witch cloth draw Fast response during wartime and orderly work is all thanks to Jiang Tao’s solid academic foundation and rich practical experience.
”Jiang Tao is a versatile. “Academician Chen Wei, head of the Military Medical Expert Group, commented on this.
Jiang Tao successively adhered to and participated in the separation of pathogenic etiology such as SARS infection cases, H7N9 infection cases, Zika infection cases, and participated in the research of dengue fever vaccines and SARS vaccines. witch cloth draw work has established a pathogen isolation technology for a series of infectious diseases, a nucleic acid detection technology platform, and a pathogenicity and transmission risk assessment platform, providing important technical support for the prevention and control of infectious diseases.
Respiratory infectious diseases have the characteristics of rapid transmission, wide coverage, and great harm. Effective early diagnosis and prevention are crucial.After years of scientific research, Jiang Tao’s team took the lead in establishing our army’s first acute respiratory disease monitoring and early warning system, and built a four-level monitoring system for the entire army. The series of technical specifications organized by the presided over are used throughout the army, greatly shortening the screening time for the respiratory epidemic.
Jiang Tao not only participated in the security tasks of a series of major domestic activities, but also went to Africa four times to Liberia, Sierra Leone and other countries to carry out medical assistance tasks.
In 2015, in order to prevent and control the Ebola epidemic, Jiang Tao went to Sierra Leone for the second time with the mobile laboratory testing team to assist in Seychelles. The testing team led by him passed the World Health Organization’s laboratory parallel energy assessment with full scores.
In 2018, Jiang Tao led the pathogen monitoring team to participate in a special simulation test by an international organization. In the virus testing module, the team successfully accurately detected pathogens such as monkeypox virus and vaccinia virus in simulated samples filled with impurities, and accurately determined the strain, achieving excellent results with full marks.

Improving the accuracy of clinical diagnosis
When I came to Wuhan, in addition to carrying out testing work, Jiang Tao also used his professional expertise in the research field to lead the testing team to screen other common respiratory infectious diseases in clinical samples.
”In the suspected and confirmed cases of new coronavirus pneumonia, whether there are other respiratory virus infections or co-infections, this is of great reference value for precise prevention and control and clinical treatment.” Researcher Cao Wu, deputy head of the Military Medical Expert Group, said.
Exploring deep-seated virus transmission and pathogenic mechanisms is the key to defeating the epidemic. Jiang Tao led a team to continue to conduct sequencing analysis for the novel coronavirus detected in clinical samples.
As the development of the virus epidemic, whether the genomic sequences have mutated and what are the characteristics of the mutations; in which regions and what are the impacts, Jiang Tao and his team are tirelessly studying and exploring.
In order to accelerate the effective integration of scientific research and clinical practice, Jiang Tao’s military medical expert group creatively used viral nucleic acid detection, antibody detection, multiple pathogen detection, and whole genome sequencing.A diagnostic chain can accurately diagnose the new coronavirus infection or other pathogenic infection of clinical patients, and it is also used in the Optical Valley Campus of Hubei Maternal and Child Health Hospital, Taikang Tongji Hospital and other hospitals in Wuhan, effectively improving the accuracy of clinical diagnosis.
When I was assigned to the task, I forgot my family. After the epidemic is over, Jiang Tao plans to accompany his family. He and his wife agreed that when the epidemic is over, they will take their wife and children to Wuhan again to see what Komiks 1960 witch cloth draw looks like after everything returns to normal, look at the Wuhan Yangtze River Bridge and the Yellow Crane Tower, and talk about their experience in fighting the epidemic in Wuhan.
The epidemic is immortal and the charge continues. This is Jiang Tao, a warrior who fights the epidemic.
