RESUMO
Objective To provide reliable reference for improving teaching methods of case discus-sion, the teaching effectiveness evaluation on classroom-site segmented discussions of a patient case was completed in internal environment system. Methods The questionnaire survey was conducted among 250 clinic students of 8-year program and of 5-year program to investigate the teaching effectiveness following implementation of the teaching plan called"classroom-site segmented study of patient case debate competi-tion seminars". The contents of questionnaire survey included: the students' view on characteristics and advantages of this teaching plan and the reasons for favoring and supporting the plan. Investigation was conducted using an anonymous questionnaire. A total of 250 questionnaires were distributed and 247 valid questionnaires retrieved. Data collection and analysis were performed by using Excel and SPSS 17.0 statistical software, percentage of each observing parameter was calculated. Results ①The students' view on ad-vantages of the plan included following: reducing students' study burden by 78.5％ (194/247), increasing the students' engagement in class activities by 85.4％(211/247), improving teaching quality in class discus-sion by 80.5％ (198/246), enhancing team spirit among students by 78.5％ (194/246), expanding students' thinking and exploring space by 84.5％ (207/245), and similarity of this teaching plan to clinical diagnosis and treatment process reached to 84.0％(197/235). ②The students' reasons for favoring and supporting this plan included: reducing students' study burden by 83.4％ (206/247), improving teaching quality in class discussion by 72.4％(179/247), and training students' ability to search clinical information by 82.4％ (203/247). Conclusion Implementation of the teaching plan, "classroom-site segmented study of patient case debate competition seminars", in internal environment system has reduced students' study burden, improved teaching quality, and effectively trained students' clinic thinking, which is widely welcomed by students, therefore providing a positive valuable reference to other discussion class.
RESUMO
To improve students' experimental research skills,innovative consciousness,promote the construction of functional experimental center,we established series of “comprehensive,contrivable,innovative” experiments in medical students.
RESUMO
AIM:To study the effects of lipopolysaccharide(LPS), interleukin-6(IL-6)and tumor necrosis factor ? (TNF?) on tissue factor(TF) expression of astrocytes. METHODS:Astrocytes were identified with anti-glial fibrillary acidic protein antibody. The TF activity of cell lysate was measured with one stage clotting assay. RESULTS:TF activity of astrocytes of LPS,IL-6,TNF? groups were obviously higher than that of the control group( P
