Objective To study the expression of p27 gene in endometrial carcinoma and its clinical significance.Methods By using streptavidin-biotin peroxidase(SP) method the expression of p27 gene were examined in 20 normal endometrial tissues and 65 endometrial carcinoma tissues.Results p27 was expressed in 33 of 65(51%) cases of endometrial carcinomas.In contrast,p27 was all expressed in normal endometrial tissues.The expression of p27 was related to the pathological grades,clinical stages and depth of myometrial invasions.Conclusion The level of p27 expression is closely related to the growth,invasion and differentiation of endometrial carcinoma.

The adhesion molecules expressed by brain microvascular endothelial cell maintain the structure and function of brain, ensure the continuity of endothelium cell and penetrate blood-brain barrier in physiology. They also intervene inflammation cells that remove or orientate regular or inflammation organism in pathology. The adhesion molecules of Immunoglobulin supperfamily and Selectin family are expressed by brain microvascular endothelial cell and have affinity with the ischemic brain damage. The advance in research on relationship between the expression of adhesion molecules by brain microvascular endothelial cell and ischemic brain damage is reviewed in this article.

Objective To analyze treatment of tubal interstitial pregnancy with Guizhi Fuling pill assisted with methotrexate and mifepristone.Methods 90 cases tubal interstitial pregnancy patients from January 2015 to June 2016 were grouped by admission order and each group with 45 cases.Methotrexate and mifepristone therapy were given the control group,Guizhi Fuling pill assisted with methotrexate and mifepristone were given the observation group.Treatment success rate,β-HCG negative time,mass disappearance time,length of hospitalization and adverse reactions were compared.Results (After treatment,treatment success rate of observation group was 91.11％and 80.49％of tubal smooth,witch all higher than control group with(88.89％,77.50％),but the difference was not statistically significant.(For the treatment of two groups of patients with success,β-HCG negative time,mass disappearance time and length of hospitalization of observation group were(13.05±1.08,24.09±1.43,15.37±0.82)days,shorter than control group with(17.39±1.50,27.43±2.19,18.85±1.)days(P<0.05).③ During treatment,adverse reactions of observation group was 11.11％,lower than control group with 26.67％(P<0.05).Conclusion Guizhi Fuling pill assisted with methotrexate and mifepristone can shorten treatment time and reduce side effects for tubal interstitial pregnancy patients.

AIM: To study the phosphatidylinositol metabolism of vascular endothelial cells exposed to projectile's pressure wave METHODS: The cultured endothelial cells were exposed to bullet's pressure wave as experimental model. The intracellular inositol-1,4,5-triphosphate(IP_3), intracellular free calcium ([Ca 2+ ]i), protein kinase C(PKC) and lactate dehydrogenase (LDH) activities in cultural medium were assayed after the cultured cells exposed to bullet's pressure wave. After blocking phosphatidylinositol metabolism with neomycin, the above biochemical parameters of cells exposed to bullet's pressure wave were also measured. RESULTS: Bullet's pressure wave induced increase in the intracellular IP_3, [Ca 2+ ]i, and PKC activity obviously. The change of LDH activity paralleled with above biochemical changes. Blocking phosphatidylinositol metabolism partially inhibited these changes. CONCLUSION: Bullet's pressure wave may activate phosphatidylinositol metabolism, which may trigger the injury to the endothelial cells and lead to leakage of plasmatic LDH.
