Objective:To extract the common factors for evaluating the teaching effect of the integrated curriculum of basic medicine in China, and to analyze and explain the practical significance of these common factors.Methods:A questionnaire survey was conducted among undergraduates of 15 medical colleges in China to evaluate the teaching effect of integrated curriculum of basic medicine, and exploratory factor analysis was conducted for screening and classification. SPSS 22.0 was used to conduct factor analysis.Results:The four major common factors evaluating the teaching effect of integrated curriculum were the effectiveness of teaching process, the rationality of teaching organization, the education of teaching content, and the innovation of teaching methods.Conclusion:The integrated curriculum reform of basic medicine should pay great attention to the simultaneous development of basic theory learning and practical ability training, the effective connection between theoretical teaching and experimental teaching, the educational role in comprehensive quality cultivation of students, and the flexible application of various teaching means and methods.

Practice and exploration of training innovative talents through tutorial system in the whole process of "5+3" integrated undergraduate education for clinical medicine specialty / 中华医学教育探索杂志

Dalian Medical University, aiming at cultivating innovative talents, has formulated and implemented a "5+3" innovative talents training reform plan. In the whole process of medical undergraduate education, tutorial system is used as the carrier to develop a phased innovative ability training system, which covers basic scientific research ability training such as courses, lectures, experimental design, papers and so on, and strengthens the cultivation of undergraduate scientific research ability. Through statistical analysis of the results of the first "5+3" students' periodic training, it is found that the proportion of "5+3" students publishing Chinese periodicals and SCI, and hosting national innovation projects and provincial innovation projects is significantly higher than that of ordinary 5-year students ( P<0.05). Although there are some problems and deficiencies in the implementation process, the basic scientific research training with tutorial system as the core has a significant effect on improving students' scientific research thinking and innovation ability, and is feasible for training medical innovative talents.

Prostaglandin E receptors in regulation of blood pressure / 中国药理学通报

Prostaglandin E_2(PGE_2)is one of the major metabolic products of arachidonic acid.PGE_2 plays important roles in various important physiological processes by binding to its G protein-coupled receptors designated EP1,EP2,EP3,and EP4,respectively.EP receptors are highly expressed in the kidney and cardiovascular system,and PGE2-mediated activation of EP receptors plays important roles in the regulation of blood pressure.The abnormal expression of EP receptors in the kidney and cardiovascular system is associated with some blood pressure disease such as salt-sensitive hypertension,renal hypertension,and myocardial hypertrophy.
