A Survey on the current general practice residency training was carried out in January 2018 among 1 114 general practitioners (GPs) who attended the standardized residency training program during 2014-2017. Basic information was obtained from the management department, other information was obtained from questionnaire. Total 1089 valid questionnaires were received with a retrieval rate of 97.8%. The survey showed that the ratios of male trainees, trainees aged 20-30 years and with bachelor degree were increasing during 2014-2017. The participants were more satisfied with the teaching quality in general hospital bases than that in community practice bases. Participants suggested to improve teaching quality, add teaching contents of humanity courses and TCM knowledge. Only14.4%(157/1 089) participants choose GPs as their career because liked this specialty. And 77.7%(846/1 089) GPs understood the main work of GP. There were 81.4%(887/1 089) participants wanted to work in; 77.7%(846/1 089) participants thought that the prospect of general practice would be excellent or good. Increasing income, professional promotion and a sense of social recognition were their wishes. Standardized residency training is crucial for general practitioners to upgrade their quality and competence, to improve training quality and to develop incentive policies are necessary.

Objective : To investigate the effect of Arginine Vasopressin (AVP) on the median preoptic glutamatergic (MnPOVglut2 ) neurons and its mechanism． Methods : Brain slices were prepared from male Vglut2-tdTomato mice．MnPOVglut2 neurons expressing red fluorescent protein were located by using fluorescence microscope．Wholecell patch clamp technique was used to observe the effect of AVP on the firing frequency of MnPOVglut2 neurons，the effect of synaptic transmission blockers ( STBs) on the AVP-induced change in the firing frequency of MnPOVglut2 neurons，and the effect of AVP V1a receptor antagonist on the AVP-induced change in the firing frequency of MnPOVglut2 neurons. Results: The mean firing frequency of MnPOVglut2 neurons increased during perfusion with artificial cerebrospinal fluid (ACSF) and AVP compared with that during perfusion with ACSF (P＜0. 01) ，indicating that AVP excited the MnPOVglut2 neurons．The mean firing frequency of MnPOVglut2 neurons still increased during perfusion with ACSF，STBs，and AVP compared with that during perfusion with ACSF and STBs (P＜0. 001) ; moreover，the magnitude of AVP-induced increase in firing frequency didn't change significantly during perfusion with ACSF，STBs，and AVP compared with that during perfusion with ACSF and AVP (P ＞0. 05 ) ，suggesting that AVP excited the MnPOVglut2 neurons directly in a postsynaptic manner．The magnitude of AVP-induced increase in the firing frequency of MnPOVglut2 neurons declined during perfusion with ACSF，STBs，AVP，and V1areceptor antagonist compared with that during perfusion with ACSF，STBs，and AVP (P＜0. 01) ，suggesting that AVP excited MnPOVglut2 neurons directly via V1a receptor． Conclusion AVP can excite MnPOVglut2 neurons via V1areceptor directly in a postsynaptic manner．This study reveals the molecular marker of MnPO neurons which AVP act on.
