Surrounding puncture can stop pathogenic qi from spreading, consolidate the connection between local meridians and enrich local qi and blood, which can eventually supplement anti-pathogenic qi and remove pathogenic qi, and consequently remedy diseases. The author of this article summrized and analyzed the clinical application of surrounding puncture for the purpose of studying this technique and improving the therapeutic effect.

BACKGROUND:Numerous studies confirmed that compared with deltopectoral approach, deltoid-splitting approach for proximal humeral fractures has good therapeutic effects, but precise superiority remains poorly understood. OBJECTIVE:To compare the therapeutic effects of deltopectoral approach and smal incision deltoid-splitting approach in the repair of proximal humeral fractures using meta-analysis. METHODS:We retrieved MEDLINE, Embase, the Cochrane library, Wanfang Database and PubMed by computer for articles on control ed trials of deltopectoral approach and smal incision deltoid-splitting approach in the repair of proximal humeral fractures published from 2010 to 2014. Neer score, operation time, intraoperative blood loss, incision length, length of hospital stay, Visual Analogue Scale score, fracture healing time, and Constant score were used as evaluation indexes of Meta analysis. RevMan 5.2 software was used for analysis. RESULTS AND CONCLUSION:Eventual y nine articles were included, total y 721 patients, published from 2010 to 2014 years. There were eight in Chinese, and one in English. Meta-analysis results showed that compared with deltopectoral approach, deltoid-splitting approach in the treatment of proximal humeral fractures could shorten operation time, reduce intraoperative blood loss, shorten length of incision, elevate Neer score and Constant score (P<0.05). No significant difference in fracture healing time, hospitalization days, and Visual Analogue Scale score was detected between the two methods of surgical approach. These data indicated that compared with deltopectoral approach, deltoid-splitting approach in the repair of proximal humeral fracture has certain superiority. Deltoid-splitting approach can be firstly selected in the permit of hospital conditions.

A blended readers training model which combines online training (micro-lecture, online class, etc) with traditional training ( face to face teaching plus computer training) was proposed according to the theories in re-lation with blended learning, and scientific strategies for interaction of readers were established, which include the 5 dimensions ( demand, object, content, resource and evaluation) in order to integrate online learning resources and traditional offline training, optimize the allocation of training resources, and improve the training efficiency.

Objective To clarify whether ethanol induced cytotoxicity of neurons was inhibited by proteasome peptidase activities. Methods A rat pheochromocytoma(PC12) was used in the present study. Cytotoxicity and proteasome peptidase activities were assessed in PC12 cells exposed to 50, 100, 150 mmol/L, 200 and 300 mmol/L ethanol. Results After 48 hours of treatment, ethanol inhibited proteasome peptidase activity in a dose-dependent manner at the concentration above 100 mmol/L. Moreover, the effect of ethanol on activities of proteasome was also in a time-dependent manner from 24 h. Cytotoxicity was still observed as ethanol concentrations increasing, started from 100 mmol/L, as assessed by MTT method. Conclusion Our results demonstrates ethanol may disturb the metabolism of protein by inhibiting proteasome peptidase activities, which is related to the toxic mechanism of ethanol on PC12 cells.

OBJECTIVE:To investigate the anti-angiogenic activity of ray cartilage glycosaminoglycans(RCG).METHODS:Primary culture of human umbilical vein endothelial cells(HUVEC)was performed,and MTT was adopted to evaluate the effects of RCG on the proliferation of HUVEC;Corneal neovascularization(CNV)was induced by sutures on Wistar rats,and CNV area was calculated to evaluate the effects of different concentration of RCG on CNV in Wistar rats.The model of mice with Lewis lung carcinoma was made to observe the effects of different concentration of RCG on tumor growth,with inhibition ratio of primary tumor measured and microvessel density(MVD)quantitated by immunohistochemical staining.RESULTS:RCG obviously inhibited the proliferation of HUVEC in vitro,with IC50 value at 62.93 mg?mL-1.As compared with normal saline group,RCG groups showed smaller areas of new blood vessels(P
