正常生理情况下，体内凝血系统与抗凝血系统处于动态平衡，使血液在血管内保持液体状态。纤溶系统是体内抗凝系统的一个重要组成部分。纤溶系统的重要作用是纤溶酶降解纤维蛋白，而纤溶酶的激活依赖于卜PA和PAI的平衡。血管内皮细胞是产生与释放t－PA的重要场所。若内皮细胞功
Under normal physiological conditions, the coagulation system in vivo and the anticoagulant system in a dynamic equilibrium, the blood in the blood vessels to maintain the liquid state. Fibrinolytic system is an important part of the anticoagulant system in vivo. An important role of the fibrinolytic system is fibrinolytic degradation of fibrin, and plasmin activation depends on Bu PA and PAI balance. Vascular endothelial cells are an important place to produce and release t-PA. If endothelial cells work
