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.

SUMMARY To summarize the experience of managing substernal goiter by totally endoscopic procedure and evaluate the curative effect , we analysed eight patients diagnosed as substernal goiter type Ⅰ and treated with totally endoscopic technique via central routing approach during March 2011 to June 2013 in Beijing Shijitan Hospital retrospectively .The feasibility , safety and curative effect of this surgical tech-nique were estimated .All the cases were successfully operated with the totally endoscopic procedure , and the pathological result showed that 6 were goiter and the other 2 were minimal papillary carcinoma .None of the patients suffered from any complication , and the median follow up time was 6 months ( 1 -28 months) .The totally endoscopic technique is a feasible , safe and cosmic one for managing substernal goiter type Ⅰ.

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.

Quality control of traditional Chinese medicine (TCM) has become bottlenecks of TCM industry devel-opment and TCM international recognition. To solve the retational problems, we explored the establishment of new quality control method based on efficacy and safety. Firstly, material basis of TCM efficacy was investigated deeply and systematically. Then, quality control method based on efficacy was established by using active ingre-dients as markers. We also establish detection methods based on safety, such as pesticide residues, heavy metals and harmful elements , mycotoxins .
