1.Problems and Countermeasures of University Teachers' Performance Evaluating
Chinese Journal of Medical Education Research 2006;0(11):-
At present,university teachers' performances are mostly evaluated by "awards and punishment system ",which desalt the encouragement and improvement function,lack of human nature concern.From the point of human resource management,guided by the theory that teachers' performances are developing,this article put forward a way of a omni bearing feedback to evaluate the teachers' performances in order to build a completely new evaluating system.

Constructing clinical teaching hospital is an effective means on resolving the lack of clinical resource,enhancing the benefit of education and ensuring the clinical quality. In order to exert hospital teaching advantage,the criteria system of evaluation on teaching hospital should be taken. Building the teaching function and awareness of hospital are highly important.

Objective: To study the distribution of Langerhans cell (LC) in oral lichen planuss (OLP). Methods: LCs in oral mucosa samples were examined with monoclonal CD1a antibody and an immunohistochemical technique(LAB method) in 35 cases of OLP and 6 cases of health control. Results: On average, in the samples of OLP the CD1a positive LCs counted under microscope in each field of 40 ? 10 were 5. 78 in epithelial cell layer and 5.43 in lamina propria, while in the samples of health control those were 0.26 and 0.18 (P

Objective: To investigate the effects of mouse recombinant Periostin on the attachment and proliferation of PDL cells on root surfaces. Methods: Normal (N) and periodontitis (P) root slices were treated with Periostin (Pe) and fibronectin (FN), respectively. Untreated root slices (Co) served as negative controls. PDL cells were seeded on the root slices, the attachment in 24h and the proliferation in 72h of the cells were determined with cell counting. The morphology of the cells was observed under SEM. Results: After 24h cultured, the cells on each mm3 on the root slices of PeN, FNN, CoN, PeP, FNP and CoP were 498. 00?31. 75, 513. 04?27. 52, 432. 88?20. 57, 336. 51 ? 27. 66, 348. 44?30. 23 and 237. 87?32. 54 respectively ; after 72h those were 683. 33? 28. 05, 774. 62?42. 25. 603. 21 ? 19. 76, 510. 52? 28. 31, 579. 19 ? 31. 58 and 445. 92?26. 30 respectively. Conclusion: Periostin can promote the attachment and proliferation of PDL cells on both diseased and healthy root surfaces.

Objective:To evaluate the biocompatibility of insulin-like growth factor I (IGF-1) gene transfected bone marrow stem cells (MSCs) with ostrich true bone ceramic (OTBC). Methods:Rat MSCs were transfected with IGF-1 gene, and positive clones were selected by G418. The expression of IGF-1 protein in the MSCs was detected by immunocytochemical technique. The IGF-1 transfected MSCs were cultured with OTBC and the morphology of the cells was observed by scanning electronic microscope(SEM) at different time point. Results:Immunohistochemical staining suggested that the IGF-1 protein was expressed in the IGF-1 transfected MSCs. The cells adhered to OTBC and stretched well after 24 h of culture. The IGF-1 transfected MSCs proliferated on the surface of OTBC with culture time.Conclusion:The OTBC has a good biocompatibility with IGF-1 transfected MSCs.

Objective To evaluate the effects of right ventricular pressure load on left ventricular ( LV) myocardial mechanics using speckle tracking technology ,and to detect the change of LV function in patients with pulmonary hypertension( PH) at a earlier stage ,in order to provide reference for early clinical intervention . Methods The study included 74 patients with PH and 40 healthy volunteers ,who had of similar age and sex distribution . According to the pulmonary artery systolic pressure ( PASP) ,patients with PH were divided into mild ,moderate and severe groups ,which were marked with A ,B ,C , respectively . All subjects underwent echocardiographic examination . Conventional echocardiographic parameters ,the systolic longitudinal ,radial and circumferential peak strain ( LS ,RS ,CS) in various segments of LV ,as well as basal and apical segment myocardial rotation angle peak and peak time were determined ,LV systolic global longitudinal ,radial and circumferential strain (GLS ,GRS ,GCS) ,free wall (LAT ,lateral wall+ posterior wall) and interventricular septum ( IVS ,anteroseptal+ posteroseptal) overall LS ,RS ,CS were calculated . Results ①LVejectionfraction(LVEF):groupA,B,Chadnosignificantreduction(P>0.05)thanthe control group . ②Overall LS ,RS ,CS of LAT of LV and IVS and GLS ,GRS ,GCS of LV :B ,C group were lower than the control group and group A and C were lower than group B ( P < 0 .05) . ③ The rotation angle in ventricular apical basal segments and segment :group B and C were lower than the control group and group A and C were lower than group B ( P <0 .05) . ④GLS ,GRS ,GCS and overall LS ,RS ,CS of LAT and IVS were similar between group A and the control group( P >0 .05) ,but LV base segment rotation of groupAwaslowerthanthatofthecontrolgroup(P<0.05).Conclusions ①Rightventricularpressure overload can lead to increased LV mechanical damage ,LV strain changes were earlier than the change of LVEF . ②LV strain with increased right ventricular pressure overload is gradually reduced . ③Compared with other strain parameters , LV basal segments rotation angle were able to detect changes of LV myocardiol mechanics in patients with PH more sensitively .

Objective ThrouGh the detection of heat shock protein 90(HSP90)Gene expression in the peripheral blood in in patients with hypertensive disorders complicatinG preGnancy( HDCP ),to understand its role in the pathophysioloGy of HDCP. Methods The expression of HSP90 was observed in Groups of normal preGnant women,Gestational hypertension patients,mild preeclampsia patients,severe preeclampsia patients by ELISA. Results The expression of HSP90 in peripheral blood of Gestational hypertension Group,mild preeclampsia Group,severe preeclampsia Group were siGnificantly hiGher than normal preGnant Group( P<0. 0l ) . Conclusion HSP90 may have close relationship with the onset and development of HDCP. It can predict HDCP by detectinG the level of HSP90 in peripheral blood.
