Objective To explore the competency of community health administrators in a survey of such administrators at large in Shanghai. Methods McClelland's Competency Dictionary was used to set two benchmark positions, while the behavioral event interviewing and questionnaires were made to survey 19 community health service centers in Shanghai. Results The competency model benchmarking on the head of a medical branch consists of 6 character clusters, 11 characteristic items, 27 evaluation dimensions and 27 typical behavior descriptions. The model benchmarking on the community team leader consists of 5 character clusters, 8 characteristic items, 21 evaluation dimensions and 21 typical behavior descriptions. Conclusion Findings of the survey provide objective criteria for competence appraisal of community health administrators, and serve as reference for formulating their development plans as well.

Objective To investigate the role of PKCδin free fatty acid-induced endothelial cell apoptosis.Methods In addi-tion,we looked for evidence of apoptosis-related PKCδsignal pathway.Human umbilical vein endothelial cells were treated with va-rious concentrations of free fatty acids and transiently transfected with PKCδsiRNA to inhibit PKCδ expression.Cell proliferation was determined through colorimetric assays,and apoptosis was quantified using flow cytometry.Protein expression was determined from cell lysates use Western blots with antibodies against p-PKCδ Tyr512,PKCδ.Statistical analyses were performed.Results Free fatty acids had multiple effects on human umbilical vein endothelial cells,including concentration-dependent inhibition of cell proliferation,induction of apoptosis,increased Fas expression,and increased PKCδ expression and phosphorylation.Inhibition of PKCδmRNA expression by PKCδsiRNA led to a reduction in free fatty acid-induced apoptosis.Conclusion The free fatty acids-induced apoptosis in endothelial cells are possibly mediated by PKCδ.

Objective To investigate the effect of estrogen on gliosis, synaptic proliferation and reorganization in hippocampus of rats with chronic epilepsy induced by pentylenetetrazol (PTZ). Methods Thirty-two Wistar rats were randomly divided into normal control group, PTZ kindling epilepsy group, estrogen+PTZ group and estrogen +Tamoxifen (mixed estrogen antagonist)+PTZ group. The PTZ kindling epilepsy group was intraperitoneally injected with 35 mg/kg PTZ once a day, then the behavior of the rats in one hour was observed. The estrogen interfered group was intramuscluarly injected of 0.6 ?g/kg ?-estradiol 6 h before PTZ injection, 1/3 d. The estrogen+Tamoxifen interfered group was injected of Tamoxifen into lateral cerebral ventricle 1 h before estrogen injection. If the severe epileptic seizures occurred three times, the rats were ready for detecting the expression of filial fibrillary acidic protein (GFAP) and synaptophysin (P38) by immunohistochemical technique. Results Epileptic seizure occoured earlier and more severely in most rats of estrogen interfered group than no estrogen interfered group. Rats in all model groups were found more astrocyte proliferation and positive synaptophysin staining, especially in the CA2, CA3 and hilar areas of dentate gyrus (DG) of hippocampus than control group. Estrogen+Tamoxifen interfered group showed significant difference as compared with other groups (P

Objective To evaluate the T cell subsets in peripheral blood of patients with gastric cancers after operation. Methods The T cell subsets of peripheral blood were determined by flow cytometry in 82 cases of gastric cancer before and after operation, and the data were compared with those of benign disease. Results Before operation CD69-positive T cell were significantly lower in cancer patients than those in control (P

Objective To discuss the correlation factors of locally recurrent gastric carcinoma. Methods Clinical, pathological and periodical follow-up datas of 50 cases with locally recurrent gastric carcinoma after radical resection from 1991 to 2005 were studied retrospectively, logistic regression analysis was used to disscuse the possible correlation factors of locally recurrent gastric carcinoma. Results 66.0% of 50 cases had recurrenced within 2 years after operations; Tumor pathological stages, positive lymph nodes and radical resection extent were independent correlation factors of locally recurrent gastric carcinoma. Conclusions Most recurrences would happen within 2 years after radical resection for gastric carcinoma; Early diagnosis of reccurrent gastric carcinoma depends on periodic follow-up observation especially gastroscope; Tumor pathological stages, positive lymph nodes and radical resection extent are independent correlation factors of locally recurrent gastric carcinoma.

Objective To observe the clinical efficacy of fire-needle acupuncture in treating myofascial pain syndrome (MPS). Method Seventy-two patients with MPS were randomized into a treatment group and a control group, 36 in each group. The treatment group was intervened by fire-needle acupuncture, while the control group was by ordinary acupuncture. The short-form McGill Pain Questionnaire (MPQ) was observed before and after the intervention, and the clinical efficacy was compared. Result The total effective rate and markedly-effective rate were respectively 94.4% and 77.8% in the treatment group versus 80.6% and 30.6%in the control group. There was a significant difference in comparing the markedly-effective rate between the two groups (P<0.01). The MPQ item scores [pain rating index (PRI), present pain intensity (PPI), and visual analogue scale (VAS)] were significantly changed after intervention in both groups (P<0.05). After intervention, the MPQ item scores of the treatment group were significantly different from that of the control group (P<0.05). Conclusion Fire-needle acupuncture is an effective method in treating MPS.

Objective To study whether the warm ischemia-reperfusion injury can be alleviated if the hepatic glycogen content were increased before liver transplantation.Methods The male SD rats as donors and recipients were divided into groups A,B and C randomly.In group A,the rats were al- lowed access to solid and water ad libitum;In group B,the rats drank glucose liquor for 4 days prior to liver harvesting;In group C,the rats were intravenously injected with 50% glucose besides the protocol in group B 3-4 h prior to liver harvesting.According to the non-heart-beating time(the non- heart-beating time were set into 60,90,120 and 150 min),the rats in groups A,B and C were divided into 4 subgroups,and the orthotopic liver transplantation was performed and the hepatic glycogen and ATP contents were measured.The one-week survival rate and the serum levels of MDA and SOD in the recipients were determined after liver transplantation.Results The hepatic glycogen and ATP con- tents in groups B and C were more than those in group A significantly(P

OBJECTIVE: To observe the effect of perioperative administration of rhubarb on the acute inflammatory response in patients with gastric cancer. METHODS: In this prospective, single-blinded, controlled clinical trial, thirty-one patients with gastric cancer operatively treated were randomly divided into two groups, with 14 patients in control group and 17 in study group. Patients in both groups were given an isocaloric and isonitrogenous enteral diet. The enteral diet was started 36 hours after operation, and continued for 6 days. Patients in the study group were fed with rhubarb before operation, and at 1 day and 2 days after operation. Indexes of acute inflammatory response such as serum C-reactive protein (CRP), interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-alpha), and indexes of nutritional status such as serum albumin (ALB), prealbumin (PA) and transferrin (TRF) were measured before operation, and at 1 day, 3 and 7 days after operation. RESULTS: Patients in both groups had acute inflammatory response, and the indexes of nutritional status decreased after operation.IL-6, CRP and TNF-alpha tested at 3 and 7 days after operation were lower in the study group as compared with those in the control group, and the recovery time of gastrointestinal motility such as borborygmus, gas elimination and defecation was shorter in the study group as compared with that in the control group. The indexes of nutritional status showed no significant differences between two groups after operation. CONCLUSION: Rhubarb can positively modulate the acute inflammatory response, promote the recovery of postoperative gastrointestinal motility, and benefit enteral nutrition support in patients who have undergone major operations for gastric cancer.

Objective To explore the application of case-based discussion combined with translational medicine teaching method in clinical teaching of gastrointestinal surgery.Methods Totally 100 undergraduates of clinical medicine in grade 2007 and 100 undergraduates in grade 2008 from the second military medical university were divided into experimental class (50 students,25 in discussion class and 25 in comprehensive class) and control class (50 students).Method of case-based discussion was applied in discussion class; method of case-based discussion combined with translational medicine was employed in comprehensive class and traditional method was used in control class.Results Scores in experimental class were superior to those in control class ; questionnaire survey showed that 90％ students thought the new model was better than the traditional model; the interests of students in exploring clinical problem in experimental class were increased (90％ vs.50％ ) ;the sense of mission and responsibility was Strengthened (86％ vs.64％ ) ;the scientific research thinking was more active (80％ vs.48％ ) ; the individual ability and quality were enhanced (76％ vs.50％ ),the depth and width of study were markedly increased (80％ vs.52％ ),the consciousness of independent study and thinking was strengthened (88％ vs.54％ ).Comprehensive class had more obvious improvements in scientific research thinking,individual ability and quality,depth and width of study,independent study and thinking.Conclusions The new teaching model which combined translational medicine with case discussion breaks through the traditional model and adapts to the requirements of modem medicine,it can enhance the teaching effect and worth promoting in educational reform.
