The results indicate that the presence of GSH increased the expression of exoY、exoS、phzA1 and gacA,while no difference was observed with others virulence factor genes tested.PAO1 produced markedly less pyocyanin than the wild type strain PAOIP＜0.01Treating with GSH, the PCN production of PAOI(△gshB was increased from 0.47μg/mL to 1.73μg/mL (P＜0.01),the PCN production of PAO1 increased from 1.3μg/mL to 1.9μg/mL(P＜0.05),this result indicates that GSH upregulates PCN production.

结果发现，GSH对启动子库中exoS、exoY、phzA1和gacA等致病性因子的表达有促进作用，对其余测试过的致病性因子则没有明显影响；铜绿假单胞菌分泌的重要致病因子绿脓菌素(pyocyanin，PCN)的含量，在PAO1中远低于PAO1P＜0.01加入GSH后，PCN平均含量在PAO1(△gshB中从0.47μg/mL提高到1.73μg/mL，差异十分显著(P＜0.01)，在PAO1中从1.3μg/mL提高到1.9μg/mL，差异显著(P＜0.05)，表明GSH对铜绿假单胞菌生产PCN有促进作用。

He experiment results indicate that (1) The extract of Rubia Cordifolia L has the effects of anti-proliferation and inducing APO;(2) Whenadministrating with 5-fu, the extract of Rubia Cordifolia L obviously enhanced the effects of anti-proliferation and inducing APO of 5-fu;(3) The basement of molecular biology of the extract of Rubia Cordifolia L for inducing APO of MGC-803 cells is correlated with inhibiting the expression of bcl-2 of anti-apoptosis gene.

UNEL法与PCNA的免疫细胞化学法的结果：0.2、0.4、0.8、1.0mg/ml浓度的茜草提取物与2、4、8、16μg/ml浓度的5-Fu，分别诱导细胞凋亡和抑制细胞增殖，表现出浓度、时间依赖性关系，除个别浓度与个别时间之间无显著性差异（P＞0.05）外，不同浓度与不同作用时间之间均有显著性差异（P＜0.05或P＜0.01），并且两种药物联合使用时，MGC-803细胞的APO%显著提高，降低PCNA的阳性表达率（P＜0.05或P＜0.01）。

Objective: To detect the expression of VEGF in human cerebral saccular aneurysm and explore the pathogenesis of aneurysm.

目的：检测VEGF在破裂人脑囊性动脉瘤中的表达，探讨脑囊性动脉瘤的发病和破裂机制。

Viral vector mainly contain adenovirus, retrovirus,adeno-associated virus and so on, but it has potential danger of safety; it isrepeled by immune system when it is injected to organism for a greatimmunogenicity. An injection with adenovirus vector with highconcentration, it leads to serious inflammatory reaction of liver. Viralvector such as liposome and polycation are commonly used lately. But,liposome and polycation have low specificness and targetness of genetransfer tissue, have lower transfection efficiency and short period ofgene expression, for they can be phagocytized by endothelial system.

许多的载体，病毒载体和非病毒载体以前已广泛应用，病毒载体主要包括腺病毒，逆转录病毒，腺相关病毒等；但病毒载体在安全性方面存在潜在的危险；免疫原性比较强，注射到机体后很快会被机体的免疫系统排斥，当静脉注射高浓度的腺病毒载体会使肝脏发生严重的炎症反应；非病毒载体目前常用的有脂质体及多聚阳离子聚合物；但脂质体和阳离子聚合物介导基因转移缺乏组织的特异性和靶向性，转染效率较低且易被网状内皮系统吞噬，基因表达时间短；因此研制新型的非病毒载体已成为研究的热点，纳米颗粒具有小尺寸效应，表面效应，随着颗粒直径变小，比表面积将会显著增大，故具有很高的化学活性，因而纳米成为了最有应用前景的非病毒载体。

Based on a cognitive analysis of the generation of voice, Croft argues that passives are functionally generated by expressing a causative event into a stative event.

Croft从认知的角度对语态经过考察得出结论：被动态产生于把过程性的事件表达成状态性的事件这一过程。
