Different from the general local hospital,the affiliated hospital of medical school plays double social roles that it not only serves as a teaching hospital but also a medical uniL Every medical staff in it shoulders the responsibility of teaching,researching and medical treatmenL According to the relative independence of affiliated hospital in comprehensive university,the particularity of professional and technical post,the multiplicity of post task,as well as problems existed in the current appraisal and appointment of professional and technical posts such as lacking objectivity and maneuverability in clinical skills examination and evaluation.the paper tries to put forward a new mode of clinical skills examination and evaluation system in accordance with the characteristics of affiliated hospital.

BACKGROUND: Nitric oxide in the central nervous system is involved in controlling the sympathetic outflow. The authors' recent data show that the reduction of nitric oxide in the rostral ventrolateral medulla (RVLM)enhanced the cardiac sympathetic afferent reflex (CSAR) evoked by stimulating the cardiac sympathetic afferent nerves in rats with chronic heart failure (CHF).OBJECTIVE: To further investigate the effect of nitric oxide in the RVLM on modulating the CSAR evoked by epicardial chemical stimulation in rats with CHF.DESIGN: Randomized controlled experiment.SETTING: Department of Physiology, Nanjing Medical University, and Department of Cellular and Integrative Physiology, University of Nebraska College of Medicine.MATERIALS: This study was carried out in the Department of Physiology, Nanjing Medical University from July 2003 to May 2004. A total of 52male Sprague-Dawley rats weighing 360-420 g were used, and were randomly divided into chronic heart failure group and control group with 23 in each group.METHODS: The rats were carried out either sham surgery or the left coronary artery ligation. Six to eight weeks later, all rats were anesthetized with α-chloralose and urethane and baroreceptor denervated and vagotomized. The CSAR was evoked by epicardial application of bradykinin (BK, 0.04 μg and 0.4 μg in 2.0 μL) to mimic the effect of chemical stimulation on the heart in the CHF state. The renal sympathetic nerve activity (RSNA), mean arterial pressure (MAP) and heart rate (HR) were recorded at baseline and during elicitation of the CSAR. Cannulae were inserted into the RVLM for microinjections.croinjection of MeTC, a nitric oxide synthase inhibitor, into the RVLM on Effects of epicardial pretreatment with lidocaine on the CSAR in CHF rats.infarction of (30.6±2.0) % of the left ventricular (LV) surface. The systolic arterial pressure, pulse pressure, left ventricle peak systolic pressure and maximum of the first differentiation of left ventricular pressure were decreased and the left ventricular end-diastolic pressure was significantly ininto the RVLM had no significant effects on the CSAR in rats with CHF,of SNAP (50 nmol) into the RVLM inhibited the CSAR in both sham rats ventricle abolished the CSAR evoked by epicardial application ofBK on the same area.CONCLUSION: Nitric oxide in the RVLM inhibits the CSAR evoked by epicardial application of BK in normal rats and CHF rats, and the reduction of nitric oxide in the RVLM led to the augmentation of the CSAR in CHF rats.

In the reform of human resource system at public institutions,public hospitals are challenged with changing employment mechanism and effective mobilization of all-staff's incentives.This paper introduced the classified staff management by Sir Run Run Shaw Hospital,College of Medicine,Zhejiang University,which covered the background,specific methods,purposes,initial results,as well as the key links and problems encountered.The study proved that classified management of the hospital staff helps create a fair and impartial workplace,conducive for sustainable development of the hospital.
