Objective:To study the influences of astragulas(黄芪) on cerebroischemiareperf usion injury in gerbils.Methods:The cerebral tissue delayed neuron death(DND) models of gerbil were established by means of ligating bilateral carotid arteries for 15 minutes then reperfusing for 48 hours and divided into shamoperation(SO) group,ischemiareperfusion(IR) group and astragulas injection (AI，黄芪注射液) group.The activities of Na ＋K＋ATPase and nitric oxide synthase(NOS) and the changes in contents of nitric oxide(NO) and excitat ory amino acid(EAA) in cerebral tissue were compared in different groups.Results:(1)In comparison with SO group the activities of Na＋K＋ATPase in IR and AI group were obviously decreased furthermore the decreases in IR group were mo re significant than those in AI group(all P<0.01).(2) The changes in co nten ts of lactic acid(LD) in cerebral tissue in all the groups had not statistically significance.(3)In comparison with SO group the activitis of NOS and the conten ts of NO in IR and AI group were reduced but the reductions in IR group were muc h more significant (P<0.05).(4)The contents of glutamic acid(Glu) in IR and AI group were higher than those in SO group and the increases in IR group w .05),meanwhile they in IR group were higher than those in AI group but the di fference was not significant.(6)Among all the groups the contents of γam inobutyric a cid (γGABA) and glycine(Gly) had not significant differences (all P>0.05).Conclusions:The mechanisms of astragulas on anticerebral ischemiareperfusion inj ury may be related to its preventing the reductions of activities of Na＋K ＋ATPase,NO S,and the decreases in synthetic volume of NO as well as its heightening the con tents of EAA after ischemia of brain tissue.

Scientific research output of clinical trials in Chinese medicine (CM) is insufficient, but international papers hold an important scientific position in China. Based on the current situation, we analyzed the present publication situation of international medical papers in our country, and the feasibility and urgency of publishing international papers on clinical trials of CM. Finally, we proposed to use the PDCA (plan-do-check-action) cycle method to improve the quality control and management of CM clinical trials. Moreover, by combining our experience in relevant scientific research launched at our department, we expounded strategies for improving the quantity and quality of international papers in CM.

Objective In order to understand the depression situation of the hospitalized tuberculosis patients.Methods Zung depression was used as a tool for assessment,the objective of 130 patients hospitalized for tuberculosis survey.Results 58.5% of the hospitalized tuberculosis patients showed symptoms of depression,compared with the secondary and 3 care patients,the rate was high among the level care patients,meaningful differences(P

Objective To observe the effects of human retinal pigment epithelium conditioned medium(HRPE-CM) on the biological characteristics of human retinal stem cells(HRSCs). Methods HRSCs were exposed to HRPE-CM and cultivated in three different cultures,including the control,epidermal growth factor(EGF) + basic fibroblast growth factor(bFGF) and HRPE-CM.Cell counting was performed to explore the effects of different culture media on the proliferation of HRSCs,and their properties as neural stem cells were further identified. Results Compared with control group,HRPE-CM significantly promoted the proliferation of HRSCs(P
