损伤统计演化方程的性质和数值模拟

, 1999
通过对一种含成核尺寸效应的损伤统计演化方程性质的分析和数值模拟，揭示了损伤率主要是由微损伤在二维相空间中的前沿的运动所决定的。这也就是Kachanov提出的损伤率演化方程的物理基础。数值结果进一步显示了含成核尺寸效应模型在损伤发展上与一维模型的区别。而且，由几种形式的细观动力学算出的损伤率与损伤的关系简单 ...

八味沉香丸激活磷脂酰肌醇3-激酶抑制铜死亡改善大鼠急性心肌缺血损伤

Zhongshan Daxue xuebao. Yixue kexue ban
目的研究藏药八味沉香丸（BCW）防治心肌缺血的有效活性部位及机制。方法建立异丙肾上腺素（ISO）诱导大鼠在体心肌缺血模型、冠脉结扎离体心脏缺血模型，评估BCW全方、醇提物及其不同极性萃取物对心电图ST段、心肌损伤、血流动力学及心肌梗死的影响。检测心肌组织磷脂酰肌醇3-激酶（PI3K）磷酸化水平、铜死亡相关蛋白的表达，以及Cu²⁺含量。利用氧糖剥夺（OGD）心肌细胞损伤模型联合PI3K激动剂和抑制剂验证通路调控关系。结果BCW全方可改善心肌缺血大鼠心电图ST段抬高（P＜0.01），降低心肌损伤标志物含量 ...
