But when his group stratified the cohort by mutation status, they observed differences in risk reduction."These results also generate the hypothesis that the protection conferred by risk-reducing salpingo-oophorectomy against specific cancers may differ between carriers of BRCA1 and BRCA2 mutations," Dr. Kauff told attendees."We found that it is highly protective against BRCA -associated gynecologic cancer in both 1- and 2-mutation carriers." And in breast cancer, his team observed a protective effect in BCRA 2 mutations.

当他的团队统计研究对象的突变状态时，他们观察到风险降低的差异性；Kauff医师向与会听众表示，这些结果也产生了藉由风险降低的输卵管卵巢成形术，对特定癌症所提供的保护效果或许会因BRCA1和BRCA2载体突变而有差异的假设；我们发现对这两种载体突变可以高度有效地对抗BRCA有关的妇科癌症；至于乳癌，他的团队观察到在BCRA2突变有保护效果。

The results of this reseach showed that administration of SF intracolonically had protective effect on the colon injury in the rat model of colitis induced by acetic acid enema, which was probably due to the mechanism of antioxidation, inhibition ofarachidonic acid metabolis and platelets activation, administration of SF intracolonically also showed protective effect on the colon injury in the rat model of colitis induced by trinitrobenzene sulfonic acid and ethanol, which was probably due to antioxidation and inhibition of macrophages activation.

实验研究表明，大鼠分别经乙酸、TNBS和乙醇处理后均出现典型的结肠炎症状，给药后分别评价结肠粘膜损伤指标、结肠组织病理变化，检测结肠组织炎症指标、结肠组织氧化损伤指标及主要炎性细胞因子改变；实验结果：阿魏酸钠对大鼠乙酸性结肠炎结肠粘膜损伤具有缓解保护作用，其机制可能与直接抑制炎症结肠粘膜花生四烯酸代谢过度，抑制血小板活化，清除大量氧自由基有关；阿魏酸钠对大鼠TNBS性结肠炎粘膜免疫损伤亦具有缓解保护作用，其机制可能与抗氧化，抑制结肠巨噬细胞活化有关。

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。
