Methods Sequence specific primers-polymerase chain reaction was used for the detection of genotypes and alleles of rs3850641 A/G loci in OX40L gene in 187 PACS cases (≤55 years) and 138 controls. Diseased vessel numbers and stenostic severity integral by coronary arteriogram and serum levels of sOX40L, C-reactive protein and vascular cell adhesion molecule-1 (VCAM-1) by enzyme-linked immunosorbent assay and nephelometry were measured. The relationship between OX4OL gene variants and PACS risk, SSI as well as plasma levels of three cytokines were analysed.

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。
