Methods The changes of contents of AGEs in plasma and the abdominal aorta and changes of VSMC of the abdominal aorta were investigated with methods of fluorospectrophotometry, immunohistochemistry, computer image analysis and transmission electron microscopy on streptozotocin-induced diabetic rats. Results From the fourth week, in diabetic rats, the contents of AGEs in plasma and the abdominal aorta increased, the relative area of α-SM-actin in the abdominal aorta decreased, the density of nucleus of VSMC increased, and mitochondria and rough endoplasmic reticules in VSMC increased.

后者在早期主要是血管平滑肌细胞(vascular smooth muscle cell， VSMC)和胶原纤维增多，弹性纤维减少，动脉增厚等，引起动脉的顺应性降低，舒张功能减弱［1～3］；晚期主要表现为动脉粥样硬化和动脉硬化，其中以VSMC的增生和迁移较为突出，其表型也由收缩型转化为合成型［4，5］。

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。
