Biochemistry and molecular biology is one of the most important professional basic courses for students in medical universities.Constructing scientific teaching quality control system for biochemistry and molecular biology is essential for improving its teaching quality.This paper discussed on some principles needed to be followed in constructing the teaching quality control system for biochemistry and molecular biology in medical universities and elucidated the three leveled frame of this system including university,college and department.This paper also illuminated on the main contents,implementation,organization system,evaluation system and incentive measures of this teaching quality control system.

Objective:To explore the application of the early clinical exposure concept-guided question-answer teaching model combined with the ORTCC (objectives, rules, training, check, and culture) model in endocrine teaching reform.Methods:Sixty-two students who interned at Beijing Anzhen Hospital of Capital Medical University from August 2022 to August 2023 were divided into control group and observation group according to the order of student number, with 31 students in each group. The control group received traditional teaching, while the observation group received early clinical exposure concept-guided question-answer teaching combined with the ORTCC model. At the end of the internship, the two groups were compared in terms of theoretical and practical assessment scores and comprehensive competency assessment scores. SPSS 22.0 was used to perform the t-test. Results:The theoretical assessment score of the control group was (87.00±3.86) points, while that of the observation group was (91.26±4.34) points, with a statistically significant difference between the two groups ( t=4.09, P<0.001). The observation group also showed significantly higher scores of clinical practice assessment and comprehensive competency assessment than the control group ( P<0.05). Conclusions:The combination of question-answer teaching guided by the early clinical exposure concept and the ORTCC model is helpful for endocrine interns to master theoretical knowledge and acquire clinical practical skills and comprehensive abilities, effectively improving the quality of internship teaching.
