MMPs are usually secreted as latent, inactive proenzymes, which need to be activated (Fig 1 ), and/or are bound to their native inhibitors, the tissue inhibitors of metalloproteinases.8 Activation may involve proteolysis and/or oxidation of the latent enzyme.8 Proteolytic activation of the proenzymes cleaves the propeptide sequence, which masks the active site of the latent enzyme.

金属蛋白酶常以无活性的酶原方式分泌，而后者要么需要被激活要么与附近的或组织中金属蛋白酶抑制物结合。激活作用包括了具有潜在酶的蛋白水解作用或氧化作用。酶原的蛋白水解激活作用能将掩盖活性部位的潜在酶的前肽序列破坏。

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。
