Objective: The aim of this study was to investigate the effects of ginsenoside Rg3 and ginsenoside Rg3 combined with cisplatinon the growth of nude mice cervical cancer, and to explore the possible mechanism of ginsenoside Rg3 and ginsenoside Rg3 combined with cisplatinin cells and molecules levels. The growth of human cervical cancer Hela cell, apoptosis of tumor cells , expression of CD31and PeNt were observed with optic microscope, radio-immunity immunological histo chemistry, terminal deoxynucleotidy transferase-mediated dUTP nick end labeling, and immunohistochemical staining. The purpose of this study is to provide a new way of medication to eure cervical cancer in clinic.

F region is one of the most important regions in the ionosphere. The night-time irregularities in this region can affect nearly all-frequency radio waves propagating through them.

电离层F区是电离层最主要的区域，尤其是其中的不规则结构，导致几乎所有波段的电磁波产生幅度和相位的闪烁。

The maximum increase of electron temperature in ionospheric F region is in the vicinity of reflect point of radio waves, and the changes of electron density have increase and decrease. The time scale of balance of electron temperature is tens of second, which is shorter than that of electron density, that is 2～3 minutes, and heating time scale for electron is good symmetry with that of cooling.

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。
