Lanzhou news (reporter) Wu Wenxuan, novel coronavirus pneumonia Research Institute of Gansu Province, was released in March 30th. The key achievements of the new crown pneumonia research field of Northwest University For Nationalities, including the backbone members of the Youth Work Committee of the Institute, Dr. Zhou Jianye of Northwest University For Nationalities and Dr. Bai Zhongtian of First Hospital Affiliated to Lanzhou University, were successfully developed. A new type of elastic silica gel swab was developed successfully, and specific sampling and sampling were recommended. The sample pretreatment process novel coronavirus pneumonia screening and clinical diagnosis accuracy. Reporters learned that since the outbreak, there have been false negative cases. Based on many years of experience in stomatology, basic research, laboratory medicine, etc. and combined with laboratory verification, the team has come to the conclusion that due to the strong absorption of mucus, it is difficult to elute the sample of flocking swab, which leads to insufficient extraction of the samples of nasopharynx and oropharynx, or may cause false negative due to the low RNA content. According to Bai Zhongtian, the main member of the scientific research team and the winner of the 9th Youth Science and technology award of our province, during the research and development of the new sampling swab, the expert team, with the help of Gansu bolijiang 3D Printing Technology Co., Ltd. and Gansu xinbaichuan Medical Equipment Co., Ltd., cleverly designed an elastic silica gel sampling test by giving full play to the advantages of interdisciplinary integration. The swab can absorb the sample with physical drainage structure and then elute the sample with elastic silica gel. It is found that the new silica gel swab can greatly increase the sampling amount compared with the existing cotton swab. At present, the novel coronavirus pneumonia has reached initial investment intention, and further in-depth research is still in progress, which is expected to contribute to the new crown pneumonia detection. Novel coronavirus pneumonia sampling and sample pretreatment procedures should be further emphasized and standardized. According to the novel coronavirus pneumonia, the researchers made specific recommendations for the two links according to the current reports and research results of the research group, which is expected to improve the accuracy of screening and clinical diagnosis of new crown pneumonia. Novel coronavirus pneumonia is the first time that Zhou Jianye and Dr. Bai Zhongtian published the same first author on preprint (BioRxiv): "flocking swabs may be a major scientific research paper that is one of the main reasons for the high false negative rate of new crown pneumonia detection, a new type of silica gel swab" (doi: https://doi.org/ 10.1101/2020.03.29.014415). It is reported that the corresponding authors of this paper are Professor Ma Zhongren, biomedical center of Northwest University for nationalities, and Professor Zhao Jin, medical department. Other authors include Liu Xiaoping, director of the second people's Hospital of Gansu Province, Guo Yaqiong, deputy director of the second people's Hospital of Gansu Province, Li Xiaodong, Ph.D. and Li Yonghong, Ph.D. of the people's Hospital of Gansu Province, all of whom are young backbone talents of the youth working committee of the bioengineering society of Gansu Province. Founded in September 2018, the youth working committee of Gansu society of bioengineering is a scientific research group under the leadership of Gansu Association of science and technology. It aims to carry out interdisciplinary research around the characteristics and current situation of major and high incidence diseases in the western region, and actively play the characteristics of young scientific and technological workers through large-scale instrument and platform sharing, academic discussion and discipline integration, so as to organize and unite Gansu Province Young scientific and technological workers have made positive contributions to clinical diagnosis and treatment and biomedical fields.
