It is indicated that MRV and street viruses have close phylogenic relation by analyzing the phylogenic tree of eachgene of MRV, and it is short evolutionary time between MRV and DRV by analyzingthe phylogenic tree of L gene. It is illuminated that MRV and street virus in China andAfrica have close phylogenic relation by analyzing phylogenic trees of other genes.Therefore, we can speculate that MRV is a Chinese street rabies virus isolated, whichis a new virus isolated because of variance and evolution of the rabies virus after itinfected mouse.

MRV的各个基因进化树表明，其与野毒株具有较近的亲缘关系，通过L基因的进化树分析，两个毒株的进化时间较短，其他基因进化树分析表明，MRV与亚洲和中国流行的野毒株具有较近的亲缘关系，所以推测MRV应该是中国固有的野毒株，由于某种原因感染野鼠后病毒进化变异而产生的毒株。

Incontrollable virus affects antibiotic, increase hepatic burden instead to patient of virus sex hepatitis.

梗概： 正确选择药物，并合理使用药物，以保证用药平安和有效是今后临床药学的重要任务，为了解把握医院临床用药目前状况及存在新问题，推动合理用药工作的发展，提高医院合理用药的水平，笔者将医院门诊、住院两处的处方进行分析探究，总结出不合理用药的几大状况，同时进行分类。1临床不合理用药的分析1·1滥用或盲目应用抗生素抗生素各科均广泛应用，使用率达70%以上，其中联用率高达40%，甚至出现二联、三联以上，最常见滥用为上呼吸道感染，入院给予2~3种抗生素治疗。1·1·1无指征的治疗用药这类不合理用药主要表现在普通感冒、水痘、带状疱疹、病毒性肝炎等病毒性感染者，在未合并细菌感染，无应用抗生素的指征下用药。

Results After six passages in BHK-21 cells, cytopathic effect was observed by microscopy. The rescued virus was rejuvenated once in unweaned mice, and then came back to cell passage. We found that the poly tract of rescued virus was shortened when the virus was passaged twice in BHK-21 cells. Although the data of LD50 in mice and TCID50 in BHK-21 cells showed that the virulence and infectivity of genetic engineering viruses were lower than its parental virus, no significant difference was observed between the genetic engineering viruses with the different length poly tract.

我们发现，基因工程毒在BHK-21上连续传代至第6代时，可见明显的致细胞病变效应(cytopathic effect，CPE)；在经过一代乳鼠接种之后再重新适应到BHK-21细胞的过程中，poly区段出现了缩短现象；乳鼠致病性试验和BHK-21细胞TCID50测定结果表明，尽管基因工程毒与母本毒相比毒力偏低，但含有不同长度poly的基因工程毒之间并无显著差异。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
