This study analyzed the current status of the cultivation process of professional postgraduates of clinical medicine, combining with the case of the auxiliary teaching model of Academic Salons on the WeChat platform in Xiangya Hospital of Central South University. We collected students' satisfaction evaluation of this auxiliary teaching model by questionnaire survey. Through analyzing the results and feedback, we found that the overall satisfaction of this auxiliary teaching model is 71.43%, and the model has a remarkable effect in broadening knowledge, inspiring thinking of clinical diagnosis and treatment, improving ability of scientific research, increasing learning interest, enhancing the ability to link theory with practice, and using the knowledge flexibly. However, there are still some shortcomings in early publicity, understanding students' interests and needs, and improving students' autonomous learning ability. Therefore, using the WeChat platform to carry out academic salons is a good auxiliary teaching model for cultivating the scientific research ability of professional postgraduates of clinical medicine.

Objective:To investigate the status of vascular access in hemodialysis patients in our center.Methods:The general information of hemodialysis patients and types and complications of vascular access at Xiangya Hospital of Central South University from April 2015 to April 2016,were retrospectively analyzed.Results:Among 258 prevalent patients,87.60％ of them had arteriovenous fistula (AVF),while 12.40％ showed tunneled cuffed catheter.Of the 61 incident patients,80.33％ of them initiated dialysis with a non-tunneled and non-cuffed catheter,8.19％ with an AVF,9.84％ with a tunneled cuffed catheter,and 1.64％ with needle puncture.The types of AVF access included 76.55％ of wrist radiocephalic fistula,7.08％ of mid-forearm cephalic fistula,11.06％ of elbow brachiocephalic fistula,and 5.31％ of antecubital fistula and transposed basilic fistula.Seventy-seven (34.07％) patients with AVF suffered complications and wherein aneurysms accounted for 24.34％.Conclusion:In maintenance hemodialysis patients,autologous AVF is the prevalent vascular access.In the beginners for dialysis,non-tunneled and non-cuffed catheter are their choice.Additional efforts and incentives may be necessary to improve vascular access during the initiation ofhemodialysis.
