ABSTRACT
Objective:To explore the collaborative innovation development mechanism of hospitals and research institutes, fully integrate the institute personnel with hospitals, and conduct classified management and performance appraisal, promoting the integrated development of hospitals and research institutes.Methods:The idea of personnel classification, the establishment of an integrated research team, and technical team groupings and service directions were determined through key informant interviews, research ability and technical strength surveys, and other research methods; The performance appraisal scheme of research teams were established by using literature analysis and optimization and Delphi expert investigation; The platform team assessment programs were established by qualitative research methods.Results:Built a position setting framework for research institutes, formed hospital-institute integrated research teams around the hospital's clinical advantageous disciplines with researchers and clinical staff, set up platform teams based on existing equipment and technicians′ specialties, established a performance appraisal scheme for research teams based on Science and Technology Evaluation Metrics(STEM), determined a full-dimensional comprehensive performance evaluation scheme for the technology platforms based on service volume and quality.Conclusions:This study formulated a set of position setting and performance evaluation schemes that fit with the current situation of municipal research institutes, and explored a new scientific research cooperation mechanism of resource sharing, team co-construction, and technology sharing, which can provide a certain reference value for the reform of other medical research institutes.
ABSTRACT
Objective:To summarize the scientific research management response strategies and practices of designated hospitals under the prevention and control of new coronary pneumonia, provide reference for the scientific and technological management of public health emergencies in domestic hospitals.Methods:Take the hospital scientific research management response under the prevention and control of the new coronavirus pneumonia epidemic in 2020 as an example, discuss and summarize the response strategies and mechanism establishment, work practice and existing problems of designated hospitals in the research management of prevention and control of public health emergencies represented by COVID-19 from the aspects of management system, resource integration, project operation, and scientific and technological service.Results:As a designated hospital of COVID-19 in Beijing, Youan hospital has actively carried out scientific and technological research on epidemic prevention and control while successfully completing patient treatment, established a scientific and efficient scientific and technological research management system, and integrated resources to form an efficient project operation mechanism, Providing a full range of scientific management services, providing policy and material guarantee for the rapid and high-quality completion of scientific and technological research on epidemic prevention and control.Conclusions:The scientific and technological research on public health emergencies has the characteristics of demand-driven, focused on key points, collaborative research, scientific decision-making, In order to carry out the research work smoothly, it is particularly important to form a benign interaction, straighten out the system, do a good job in long-term planning and layout, and establish a scientific and efficient research and management mechanism.
ABSTRACT
Objective To study clinical features and mechanism in patients suffered from chronic hepatitis B achieving seroconversion of HBsAg by combination treatment with interferon (IFN) and nucleoside analogue (NA). Methods Thirty-two cases with chronic HBV hepatitis were enrolled into this retrospective study. All of them received combination treatment with IFN and Lamivudine/Adefovir, as well as achieved seroconversion of HBsAg from June, 2001 to May, 2007. All the cases in this study were followed up. Results Generally, serum HBV DNA fell below the detection limit 3 to 6 months after starting combination treatment. Virological breakthrough/relapse or new clinical resistant had not been found in all enrolments after combination treatment, including patients with previous resistant to Lamivudine, although the average length of treatment was over 2 years. The average period of following up after seroconversion of HBsAg was 13.2 months. Two cases transfered back to HBsAg positive, one of them achieved seroconversion of HBsAg again by the anti-virus treatment, and the other one gave up treatment and remained anti-HBe positive and HBeAg negative.The other 30 eases kept at the stage of seroconversion of HBsAg. Seven patients underwent liver biopsy after seroconversion of HBsAg, and 3 of them had taken liver biopsy before combination therapy too. Biopsy specimens were scored for fibrosis and neeroinflammation according to the Knodell histological activity index. Six cases showed HBsAg and HBcAg negative by immunohistochemistry,and only 1 case with HBsAg positive in liver tissue experienced relapse. Inflammation and fibrosis grade of the 3 cases who had taken liver biopsy twice were lowered after HBsAg seroconversion,although the ALT level of 1 case who had turned from G2S4 to GIS2-3 remained abnormal after HBsAg seroconversion. According to the sequence and character of HBsAg seroconversion, there were three models of HBsAg conversion. The sequence of transition was HBV DNA→HBeAg→HBsAg,which was dominant one, accounting for 59%(19/32 cases). HBV DNA negative, and the titer of HBeAg wandering at a low level, after then HBeAg and HBsAg change to negative in the same time,31% (10/32 cases). The titer of HBsAg decreased rapidly after the HBV DNA clearance, and the HBsAg clearance was earlier than HBeAg, 9% (3/32 cases). After 1 year of combination therapy,there were 15 of 21 cases (71.4%) whose titer HBsAg showed less than 100 COI by agent from Roche, and 7 of 11 cases (63.6%) whose titer HBsAg showed less than 250 IU/L by agent from Abbott. The frequency of adverse reaction was similar with that induced by IFN monotherapy, and no new adverse reaction was found. Conclusions Combination therapy and long course treatment might be the key to achieve the HBsAg seroconversion. Those with HBsAg in liver tissue and (or) low serum anti-HBs are more likely to relapse. The titer of HbsAg<100 COI (Roche, Germany) or<250 IU/L (Abbott, USA) after one year treatment may be regarded as a predict index of HBsAg seroconversion.
