Objective This paper mainly introduced the present situation of the local talents at Peking University Health Science Center,and proposed some corresponding suggestions for further development.Methods By using the methods of questionnaire investigation and literature review to acquaint the current situation of the local talents.Results The local talents face greater pressure of living stress,their material well-being needs to be improved,physical and psychological condition is poor,and the relationship with the returned overseas talents needs to be adjusted.Conclusions Several suggestions,such as mainly from the structural reform of local talents incentive mechanisms,the improvement of local talents distribution,the attention of the interests of local talents,the strength of self-construction and the coordinated development with overseas talents to promote the construction of the aspects of local talents.

Objective The measures and suggestions for the management of returned research talents in our country.Methods Through the study of the development of returned research talents in the last five years,Peking University Health Science Center.Results The country has provided a good working and living environment for the returned research talents,but the domestic treatment still has a gap with foreign countries.The differences between the domestic and foreign may cause psychological gap,not easy to adapt.Returned research talents have their own advantages in scientific research,teaching and other aspects,but the research output is relatively slow.Conclusions In terms of policy,academic environment and working environment should be improved.

〔Abstract〕 The paper elaborates the definition of Biobank and the significance of constructing Biobank standardized system, through comparison of Biobank development process and experiences between China and abroad, it analyzes the existing problems and reasons of Biobank standardized system construction in China, puts forward corresponding advices.

We searched and retrieved literature on the topic of medical image processing published on SCI journals in the past 10 years. We then imported the retrieved literature into TDA for data cleanup before data analysis and pro cessing by EXCLE and UCINET to generate tables and figures that could indicate disciplinary correlation and research hotspots from the perspective of bibliometrics. The results indicated that people in Europe and USA were leading researchers on medical image processing with close international cooperation. Many disciplines contributed to the fast development of medical image processing with intense interdisciplinary researches. The papers that we found show recent research hotspots of the algorithm, system, model, image and segmentation in the field of medical image processing. Cluster analysis on key words of high frequency demonstrated complicated clustering relationship.

Technology readiness level (TRL) refers the general maturity level of a single technology or technical systems (including technology,component or subsystem) during the process of development.Base on the original TRL proposed by NASA,with reference to medical device TRL modified by US Department of Defense and NATO,this study modified TRL definition and description for advanced medical devices with consideration of R&D,review and approval characteristics of advanced medical devices in China.

Through the analysis of the current status and problems of innovative medical devices evaluation, tnis paper discussed the strategies of evaluation, and ultimately raises the frame of evaluation, so as to provide reference for scientific evaluation of medical devices in China.

Objective To review the "Twelfth Five-Year Plan" and provide the outlook of the innovation system of Chinese medical science and technology in "Thirteenth Five-Year Plan".Methods This article mainly investigates the layout and results regarding innovation system of Chinese medical science and technology in "Twelfth Five-Year Plan" and the "Thirteenth Five-Year Plan" respectively.Results The layout of the "Twelfth Five-Year Plan" in medical technology field has provide guarantees for promoting the construction of healthy China.Meanwhile,Chinese innovation abilities in this field has been improved.Additionally,technology and equipment in China have been upgraded.However,there are still some problems,such as the lack of original research innovation capacity and urgency in the task of product quality upgrading etc.Since the "Thirteenth Five-Year Plan" is considered as the decisive stage in the process of building Chinese well-off society,it is necessary to increase the layout and investment in terms of innovation system of Chinese medical science and technology.Conclusions On the basis of "Twelfth Five-Year Plan","Thirteenth Five-Year Plan" will grasp the direction of technological progress of medical industry,and continue to promote innovation as well as provide support for improving the abilities of research and development,which could provide an inexhaustible driving force of medical technique innovation for China.

The key factor responsible for the slowness of registration of medical devices in China is clinical trial. The clinical trial in European and U.S. is taken as an example to analyze the problems in clinical trials in China. Some suggestions are proposed to solve the problem.

Objective:By building a COVID-19 related scientific research progress monitoring system, to mitigate the information needs of different stakeholders such as government decision-makers, enterprises and scientific research institutions, provide reference for global scientific research progress monitoring for possible public health emergencies in the future.Methods:Literature review and expert consultation were adopted to systematically sort out the data sources of journal papers, preprints and other scientific papers, formed their respective monitoring catalogs and determined the tracking path.Results:COVID-19-related papers mainly include journal papers and preprints. The data source monitoring range of journal papers includes the official websites of top journals in biomedical and natural sciences, the database Web of Science and Science Direct, and the monitoring scope of the preprint platform includes medRxiv, bioRxiv, and SSRN, etc. In addition, the virological websites virological and nextstrain should also be monitored.Conclusions:COVID-19-related scientific research progress monitoring system can be used for daily monitoring to provide support for decision-making and deployment of prevention and control work.
