In midnight Yangcheng, the third level biosafety laboratory of Guangzhou Customs Technology Center is brightly lit. Under the lamp, Shi Yongxia, a representative of the 20th National Congress of the Communist Party of China and chief physician of the Health Quarantine Research Institute of Guangzhou Customs Technology Center, was busy busy with the buzzing sound of the inspection instruments. This two-story building is the “battlefield” she has been holding on to for many years, and her “enemy” has plague, cholera, malaria, and influenza that have been endangering humans for hundreds of years, as well as various new infectious diseases such as Ebola hemorrhagic fever, Middle East respiratory syndrome, and new coronary pneumonia. There are challenges, dangers, and more responsibility and mission here.
Racing with the virus day and night
In 2006, after Shi Yongxia left the post-doctoral post-doctoral school in Basic Medicine at Southern Medical University, she went to the experimental room of Guangzhou Customs Technology Center to engage in infectious disease-related research, and also established an inseparable relationship with port health and epidemic prevention work.
“The first thing to do when competing with the virus is to identify it as quickly as possible. I am a customs technician and a Communist Party member, and I must take the lead in scientific research.” On the eve of the Spring Festival in 2020, the new crown pneumonia epidemic broke out. Shi Yongxia, who originally planned to go back to her hometown in Henan to visit relatives, retired from the highBabaylan‘s iron ticket and returned to the laboratory to face the unknown virus.
On New Year’s Eve, BabaylanAt dawn, Shi Yongxia plunged into the laboratory and began sample testing. At that time, the research on the new coronavirus was still in the exploration stage, and the reagents were still immature, which had extremely high requirements for the operation of the experimental personnel. Shi Yongxia was fully focused, striving to be scientific and rigorous in every link and to be accurate and accurate in every step. She understood that on New Year’s Eve, on the port and in the hospital, there were thousands of Communists fighting on the front line like her, “Everyone is practicing the same oath in different positions.”
After continuous fighting, Shi Yongxia and her colleagues finally completed all sample tests at 4 a.m. on the first day of the Lunar New Year. Everyone said “Happy New Year” across the face screen and continued to invest in the next shift.
In every festival where thousands of families reunite,The staff of Guangzhou Customs Technology Center are all sticking to their positions in the laboratory. Shi Yongxia said: “We are on the front line of the port, with national gates ahead, and people behind us. Our team deeply understands the complexity and arduousness of the anti-epidemic work, and dare not relax at all. Only when we run faster than the virus can we maximize the safety of the people’s lives.”
Focus on technical research and build a solid scientific and technological defense line
One night in early February 2020, Shi Yongxia was conducting virus isolation on an important sample of infected cases. After several days of observation and multiple methods to confirm that when the cells arranged in the screen, which were arranged in a regular manner like frosted glass, appeared to be bumpy and became lumps, Shi Yongxia knew that she had finally successfully located the strain. The successful isolation of the strain provides valuable seed resources for the next step of screening therapeutic drugs and research institutions for vaccine development.
Diven heading into the laboratory does not mean deaf ears. Shi Yongxia has always been very concerned about the epidemic situation at home and abroad, and has carried out technical research or technical reserves in advance in order to establish a fast, accurate and efficient detection method.
In view of the rapid mutation speed of the new coronavirus and strong transmission ability, Shi Yongxia’s tracking has been accelerating. She led the team to establish a gene sequencing and bioinformatics analysis platform, carry out whole-genome sequencing, and strive to unravel the secrets of the source and transmission chain of the epidemic.
The key links of gene sequencing require pure manual operation, which is highly technical. Shi Yongxia led everyone to successfully test again and againKomiks discovered a variety of variant strains, providing professional support for the work of epidemiological investigation and tracing, and also providing important experimental data for the changes in the development strategies of nucleic acid detection reagents and vaccines in the new coronavirus.
Ambition to strive for the national health causeBabaylanIn January 2012, Shi Yongxia joined the Communist Party of China and practiced the “forward” href=”https://comicmov.com/”>CinemaCommunism struggles for life” vow. During the 16 years of infectious disease-related research, she has confronted the virus head-on, detected the first imported chikungunya case in my country, successfully isolated the MERS (Middle East Respiratory Syndrome) coronavirus for the first time, established new Zika virus detection technology and virus isolation methods, and gradually grew into the backbone of my country’s port public health and epidemic prevention field.
In scientific research, Babaylan has been in the Babaylan industry. Komiks has achieved fruitful results, but she said calmly: “It is a lucky thing to be able to combine your personal ideals with the Komiks in the country. ”
The four seasons have changed, and the lights in the laboratory are still extinguished all night. They have witnessed Shi Yongxia’s years of fighting against the virus on the front line of the country, carrying her unchanged original intention. She said, “As a grassroots party member and a grassroots staff member of the customs, in the future, I will fully implement the requirements of ‘the epidemic must be prevented, the economy must be stabilized, and the development must be safe’, and strengthen the interdisciplinary collaborative innovation research across the territory, and actively take responsibility with a more full spirit, and demonstrate the determination and confidence of customs personnel to do a good job in epidemic prevention and control at ports and promote foreign trade growth. ”
