Objective To explore the effect of bcl 2 in vascular smooth muscle cells(VSMC) apoptosis induced by nitric oxide(NO),we investigated the effect of NO on Bcl 2 protein expression in cultured vascular smooth muscle cells(VSMCs),and effect of Bcl 2 over expression on apoptosis is(VSMCs) induced by NO. Methods Cultured rat VSMCs at passage 5 to 8 were used for experiments,S nitroso N acetypenicillamine(SNAP) was used as NO donor.Cells were preincubated for 24-48 hours in special culture dish with conditioned medium to reach quiescent,and then incubated in conditioned medium containing 0 5 mmol/L SNAP.After 8 to 10 hours,the cells were fixed and Bcl 2 expression was analyzed by ACAS 570 through fluorescent immunochemistry.Vascular smooth muscle cells were transfected with bcl 2 gene through retrovirus to allow overexpression of Bcl 2 in VSMCs.Finally,we observed the apoptosis in normal VSMCs and VSMCs infected with bcl 2. Results SNAP downregulated Bcl 2 expression in VSMCs.PCR and Southern hybridization confirmed the integration of the bcl 2 retrovirus vector into vascular smooth muscle cells genomic DNA.And fluorescence immunohistochemistry confirmed that Bcl 2 protein was overexpressed in VSMCs infected with bcl 2.And ratio of apoptosis become lower in VSMCs infected with bcl 2. Conclusion bcl 2 can inhibit apoptosis of VSMCs induced by SNAP.It is suggested that downregulation of Bcl 2 protein is one of the ways in which SNAP induces VSMCs apoptosis,and apoptosis in VSMCs induced by SNAP is regulated by bcl 2.;

Objective To analyze the clinical utility of TCM decoction pieces for reinforcing deficiency in the First Affiliated Hospital of Xi'an Jiaotong University (hereinafter referred to as our hospital).Methods By using Microsoft Office Excel 2013 software, use frequency, classifications of pharmacological actions and doses of the TCM decoction pieces for reinforcing deficiency from 2013 to 2015 were analyzed.Results From 2013 to 2015, some TCM decoction pieces for reinforcing deficiency showed relatively high use frequency in our hospital (>30%). In top 15 TCM decoction pieces for reinforcing deficiency, the amounts of medicine for tonifying qi were more than 40%, whose average doses exceeded the upper limit of pharmacopoeia dosage reaching 30%. The total over-use rate of TCM decoction pieces for reinforcing deficiency>50% and the not exceeded part accounted for 36.0%.Conclusion It is suggested that the use of TCM decoction pieces should be careful differentiation of symptoms, and the dose should also meet the specifications.

Animal model of aged rat nephrotoxicity was induced by i. p. administrationof gentamycin in a dose of 140mg/kg/day. Part of those rats were treated with CordycepsSinensis(CS), Epimedium(Ep) and Astragalus Membranaccus (AM) in form of decoc-tion per Os and others seryed as control. The results were summarized as. 1. The nephro-toxicity of gentamycin was aggrevated with age. CS, Ep and AM are effective drugs inpreventing the tdeular damage caused by gentamycin in rats. The pathological changes ofrenal tuoules of the rat groups which treated with CS, Ep and AM were less severe thanthat of the control. 2. CS, Ep and AM could prevent the decline of renal cortical Na~+-K~+-ATPase activity of aged rat induced by gentamycin.

This paper aims to analyze Professor Guo Rongjuan's medication experience on insomnia therapy based on the Traditional Chinese Medicine (TCM) Inheritance Support Plat. First, TCM formulae prescribed by Professor Guo for insomnia therapy were collected from the TCM Inheritance Support Plat. Next, unsupervised data mining algorithms, including apriori, modified mutual-information, and entropy clustering of complex system were applied to obtain the frequencies for different herbs and identify the association rules among the herbs. Accordingly, we can gain new insights into Professor Guo's medication experience on insomnia therapy. Based on analysis of 3 084 formulae, we determined the frequencies for herbs in the formulae and identified the association rules among these herbs. At last, 41 core combinations and 7 new formulae were obtained. The identified medication experience conform with Professor Guo's views on the etiology and pathogenesis of insomnia: "pathogenic fire derived from stagnation of liver-QI (Gan Yu Hua Huo)" is the core pathogenesis of insomnia; "liver stagnation and spleen deficiency" and "chronic illness transferred to kidney" are the main features for insomnia. The TCM Inheritance Support Plat is of great practical value for mining clinical experience of famous TCM doctors.
