Clinical teaching is the critical stage for medical students turning to qualified doctor. In order to overcome the objective problems of insufficient clinical case resources

using the electronic medical record system to collect cases

the real case library of kidney disease was initially constructed

which was presented in the form of network resources. This case database was applied to assist teaching in the proba-tion of eight year medical students at the undergraduate stage

and the application of the case database was evaluated in the form of questionnaire. It is found that case database is helpful to students' clinical learn-ing

and has the necessity of further improvement and good prospects for popularization. It provides a new idea for clinical teaching.
