Isolation and purification of BVⅠ-2H from bee venom and analysis of its biological action

The medical use of bee venom for rheumatoid arthritis ( RA ) has a very long tradition. In this study, isolation and purification of polypeptides from bee venom were carried out on sephadex chromatography, heparin sepharose CL-6B chromatography and HPLC. Several fractions were extracted, and their effects on activation of splenocyte and THP-1 cell were studied. The inhibitory fraction was selected for further studies. Finally, BVⅠ-2H that the HPLC elution profiles was a single peak was isolated by C8 column. ESI- MS detection results showed that BVⅠ-2H was a fraction of bee venom, and the molecular weight of the major component was 644.8. BVⅠ-2H could inhibit ConA-induced splenocyte proliferation, IL-1 production and interfere with splenocyte cycle in mice. Moreover, BVⅠ-2H could inhibit PMA-induced TNFα production in THP-1 cells, which was due to its inhibitory effects on TNFα mRNA expression and protein phosphorylation of IκBα. Our studies indicated that BVⅠ-2H was one of the anti-inflammatory components of bee venom.

Analysis and compare of location technologies supporting LBS

Location technology is the key part of location based service. Different technologies have different accuracy, modifying to network and cost of operating. Also these technologies have limitation to network. This paper compares existing popular location technologies and gives some suggestions about choosing of location technologies in GSM and CDMA systems.     

基于改进等分节点法的启发式布局算法

针对集成电路标准单元模式的布局问题，提出了一个全新的基于改进等分节点法的启发式标准单元布局算法(TETP)，该算法在优化布局过程中采用改进的等分节点法寻找单元目标位置，同时结合局部寻优的启发式算法，对MCNC(Microelectronics Centre of North-Carolina)标准单元测试电路进行实验。结果表明，与布局工具Timber Wolf7．0和FengShui相比，电路布局的总线长度分别平均减少了16％和17％。     

也论民事执行权的性质及其配置

通过对民事执行权性质的剖析,认为民事执行权当属兼有司法权和行政权特征之独立的国家公权力;进而基于国情认为我国应采用“独立核心一元制”的执行机构模式,即将民事执行机关设置在检察院系统,设置相对独立的民事执行科,而在法院系统保留执行法官,并以民事执行科为核心组织多种国家力量完成执行程序。     

构树形成层细胞超微结构的周期性变化

构树(Broussonetia papyrifera)形成层细胞超微结构具有明显的季节性变化,休眠期形成层带细胞壁比较厚,具有许多小液泡,细胞核占细胞体积较大,核质稀疏,内质网为光滑型,核糖体分散在细胞质中,脂质体较多,活动期形成层带细胞层数较多,细胞壁比较薄,纺锤状原始细胞中具1—2个大液泡,而射线原始细胞具许多分散的液泡,这在双子叶植物中还未报道过,细胞质沿细胞壁分布,核膜明晰,核质浓密,内质网为粗糙型,上面附有大量的核糖体,脂质体较少,在休眠和活动期都有淀粉积累,线粒体、微管和内质网大量分布在初生纹孔场附近,而且有大量的小泡沿细胞壁分布,这有可能与细胞壁的形成有关。
