ABSTRACT
Integrated experiment course is beneficial to optimizing the whole structure of medical courses and plays an important role in improving medical students' comprehensive quality and innovation capability. After several years of reform and exploration, Shanghai Jiao Tong University School of Medicine has developed the medical functional integrated experiment course with concept of "strengthen quality, reinforce foundation , encourage innovation and provide professional service", established a diversified evaluation system, and developed a corresponding assessment scale for reviewing students' comprehensive ability and the quality of experiment teaching. This paper investigated and prospected how to construct and optimize this evaluation system from the aspects of the relationship between evaluation method and course structure, and their effects, so as to provide strategic guidance for the further development of integrated experiment course.

ABSTRACT
Objective · To design and synthesize five new tropane compounds, and test their antagonistic activity against M3 receptor and inhibition activity to neutrophil elastase (NE), of which the structure-activity relationship were preliminarily investigated. Methods · The five compounds, A1-A3,B1 and C1, were prepared with 3α-hydroxy-tropane (A0) as the starting material by modifying the structure in C-3α position and N atom on the tropane skeleton. The antagonistic activity of the compounds to muscarinic M3 receptors on tracheal rings of guinea pigs was evaluated by functional assays in vitro. The hydrolysis of PGlu-Pro-Val-PNA as substrate was catalyzed by NE to get colorful nitroaniline (PNA). The NE inhibition activity of the tropane compounds was obtained by determining the absorbance [(D(405 nm)] of PNA. Results · The five new tropane compounds generated strong antagonistic activity against M3 receptors. Among them, A2 had the greatest activity [antagonistic parameter pA2(M3)=9.004], and elicited obvious inhibitory effect to NE (inhibition ratio YA2=20.29%). Conclusion · Introducing strong electron-attraction group, such as sulfuryl and hydrophobic group with large volume into C-3α position on the tropane skeleton can improve the M3 receptor antagonistic activity as well as the NE inhibition activity.
ABSTRACT
To cultivate high-quality medical talents,Shanghai Jiao Tong University School of Medicine established a multidisciplinary and comprehensive basic medical practical integration curriculum Medical Functional Experiment.Over several years' exploration and renovation,insisting on student-centered,this course has established a modular experiment teaching system with emphasis on foundation,combina-tion with clinical and focusing on innovation.Integration curriculum adopts four-stage teaching pattern which is suitable for medical students,and implements diversified teaching method and evaluation system.And meanwhile,the paper explores the ideas and approaches to further deepen the construction of teaching staff,expand experimental teaching techniques,strengthen the construction of curriculum materials,and strengthen the cultivation of teachers' innovative ability.
