Objective:To discuss the role of Fas/FasL-mediated colonic epithelial apoptosis in the pathogenesis of ulcerative colitis(UC).Methods:Expression of Fas,FasL and M30(a new epithelium apoptosis marker) antigen on colonic mucosa of 35 patients with UC and 15 control populations were detected by IHC.Each marker was analyzed by image analysis system.Co-expression of Fas and M30 was observed through serial sections and double staining IHC.Results:The expression of Fas,FasL as well as M30 in UC increased considerably compared with controls (P

Neovascularization is one of the crucial challenges in tissue-engineered grafts.In order to find sdution to the problem,endothelial cells and animals were exposed to electromagnetic fields to examine the formation of new vascular.This review gives an overview of the effects of electromagnetic fields on the neovascularization of tissue-engineered grafts.

Delayed cerebral vasospasm is the leading cause of death in patients with subarachnoid hemorrhage. A good in vivo animal model of cerebral vasospasm after subarachnoid hemorrhage helps to understand the occurrence, development of this cerebral vasospasm, and the complicated and various pathophysiological mechanisms. It will provide important information for clinical interventions

ObjectiveTo explore the effect of Songlingxuemaikang combined with losartan on the blood pressure and quality of life in female patients with menopausal hypertension.Methods87 female patients with menopausal hypertension were randomly divided into combined group (Songlingxuemaikang combined with losartan group,44 cases) and the control group(losartan alone,43 cases).Before and after treatment the ambulatory blood pressure (ABMP) was monitored for 24h,and blood lipids and clinical symptoms were observed.ResultsAfter two months treatment,the blood pressure variability and nighttime blood pressure decrease rate of the combination group significantly reduced,and better than those of the control group( all P ＜0.05) ;The effective rate and efficiency rate of the combination group were 90.9％,63.6％ respectively,and was higher than 74.4％,39.5％ in the control group( x2 =4.15,5.06,all P ＜ 0.05 ).The clinical symptoms improving,total cholesterol ( TC ) reducing,density lipoprotein (LDL-C) lowing in the combination group was superior to the control group( all P ＜ 0.05).ConclusionSonglingxuemaikang combined with losartan in treatment of female patients with menopausal hypertension had a good antihypertensive effect,and could reduce blood pressure variability in menopausal women,improve the symptoms of menopause and lipid metabolism,incresse the quality of lfie of patients with menopausal hypertensive.

Atherosclerosis (AS) is a multi-factor disease,with complex etiology.It is associated with vascular abnormalities and changing vascular wall composition.AS mainly involve large and medium sized arteries,which may cause multiple organ lesions including heart and brain tissue ischemia and necrosis,myocardial infarction,stroke and other serious diseases.Its pathogenesis has not been finally clarified.This article gives review on pathological changes,etiology and mechanism of AS,as well as its imaging performance.

The development of renal transplantation from living relative donors relives the shortage of transplanted organs,and benefits patients with end-stage renal diseases.However,when seen from the aspect of donors,implementing a non-therapeutic invasive surgical treatment on a healthy person still violates the absolute sound principle of medical ethics.To reduce the harm to the minimum,a comprehensive assessment should be conducted before the transplantation,and long-term follow-up observations after transplantation should also be strengthened.

Studying of atherosclerosis is more than a hundred year.There are many theories about this disease,but now most of us seems to agree with the stress-reponse theory.Heat shock proteins are the products produced at the first stage of atherosclerosis.And someone think that it may have something to do with atherosclerosis.This paper discussed the heat shock proteins and atherosclerosis respectively,and emphasized the relationship between them.

Objective:To observe oncosis in human peripheral blood T lymphocytes.Methods:Peripheral blood T lymphocytes of healthy adult was separated with Percoll(1.073 g/ml)and harvested by using nylon column.The cultured cells were divided into control and dexamethasone(DXM)group,and cell morphology was observed through light microscope,electron microscope and fluorescent microscope.And incidence rate of oncosis was analyzed by flow cytometry.Results:①Oncosis could be observed in cultured T lymphocyte after 96h.②In different concentrations of DXM group(1?10-6,1?10-5,1?10-4,1?10-3mol/L),The incidence of oncosis T lymphocytes was(3.49?0.42)%,(5.17?0.48)%,(8.44?0.72)%,(17.93?1.50)%.③During different cultured period(48,72,96,120h),The oncositic rate of T lymphocytes in DXM group was(0.53?0.10)%,(6.36?0.80)%,(20.60?1.59)%,(25.56?1.76)%.Conclusion:Oncosis can be seen in human peripheral blood T lymphocytes,and DXM could induce oncosis.
