Objective To observe the clinical efficacy of deep electroacupuncture at Baliao points intreating chronic pelvic inflammatory disease (CPID) due to damp-heat stagnation.Method Sixty-four patients with CPID due to damp-heat stagnation were randomized into two groups, 32 cases in the deep-electroacupuncture group and 32 cases in ordinary-electroacupuncture group, 10 d as a treatment course, and the therapeutic efficacy was evaluated after 2 treatment courses. The pre-treatment and post-treatment body sign scores and the change of the scores in the two groups were compared.Result The total effective rates were respectively 93.8% and 75.0% in the deep-electroacupuncture group and ordinary-electroacupuncture group, and the improvement of body sign score in the deep-electroacupuncture group was statistically more significant (P<0.05).Conclusion Deep electroacupuncture at Baliao points can produce a significant efficacy in treating CPID due to damp-heat stagnation.

Objective:To study the biologic characters of human foreskin fibroblasts(HFF)to lay the foundation for a long-term culture for human embryonic germ cells in vitro.Methods:The method of separating HFF was investigated.By immunocytochemical method,MTT and flow cytometry,we investigated the morphology and the purity of HFF,study the cell growth curve and cell cycle of HFF,and the effects of different concentrations of mitomycin on growth of HFF at different times.Results:Epidermis and dermis were more easily separated after overnight digestion(12~16 h)in 0.25% Trypsin at 4℃,compared with incubation for 2 h in 5% CO2 at 37℃.Vimentin was strongly positive stained with the purity of 95 percent.There was no obvious stranded period.The rapid proliferation period was in 1~6 d of cell growth curve.The platform stage began at 7 d.Majority of the cells were in G1/G0 phases.The cell cycle corresponded to cell growth curve.Mitomycin C(MMC)inhibited the proliferation of HFF at 12.5 ?g/ml over 2.5 h of MMC treatment.Conclusion:Its biological characters showed that HFF can be used as feeder layer for in-vitro cultured human embryonic germ cells。

AIM: To verify the protection of astragalus polysaecharide (APS) on H2O2 - stressed skin fibro-blasts. METHODS: A model of acute H2O2 stress in primary skin fibroblast was used at concentration of 0.5 mmol/L by 30 rain incubation. Dose responses of APS on cell survival was measured by MTI, cell death was evaluated by DAPI, and effect of APS on mitochondria, mitochondrial membrane potential and lysesome stabilization were measured by confocal microscopy. RESULTS: APS improved cell survival in a dose -dependent manner, starting at 0. 5 mg/L and with a maximum at 1 mg/L. Moreover, APS inhibited mitochondrial membrane potential collapse, protected mitechondrial morphology and stablized lysosomal membrane. CONCLUSION: The results suggest the existence, at the mitochondria-lysosome level, of a new pathway of apoptotic regulation by APS. This might constitute a new therapeutic target where oxidative stress and lysesomal impairment are involved.

Problems in pathology teaching requires the introduction of PBL pedagogy.Teaching experiments show that PBL teaching has a positive impact on the improvement of clinical medical students'ability and quality and can be conditionally applied and promoted. And at the same time, it is a challenge to traditional teaching mode of pathology and therefore the reform of medical education needs to be deepened.

Objective To explore effective health education methods about diabetes mellitus and increase the health education qulity for patients with diabetes mellitus.Methods Patients with diabetes mellitus(192 cases)were divided into the test group and the control group with 96 cases in each group.The control group received routine health education.Health education pathway inventory was established for patients in the test group.The concrete aim of health education was considered and objective teaching method was used combined with clinical pathway.The health education effect was compared in the two groups.Results The excellent rate of health education knowledge and total satisfactory rate with nursing service in the test group was higher than that of the control group(P＜0.05).The blood slucose control in the test group Wag better than that of the control group(P＜0.05).Conclusion Objective teaching method combined with clinical pathway proved to be an effective health education method for diabetes mellitus.
