纤维蛋白溶解系统即纤溶系统对人体血液保持流体状态与正常运行具有重要作用。研究发现纤溶系统的物质还具有很多新的生理功能。如纤溶酶原具有抑制血管内皮细胞增殖的能力 ;PAIS与t-PA的相互作用 ,动态平衡调节着滋养层细胞浸入子宫壁 ,绒毛间隙血窦中纤维蛋白的溶解等重要的生理过程 ;PAI- 1可能通过抑制肿瘤细胞凋亡而促进肿瘤细胞生长 ,是一系列肿瘤发生时的不祥预兆因子等等。因此 ,进一步认识纤溶系统物质的功能很有必要 The fibrinolytic system, fibrinolytic system, plays an important role in maintaining the fluid state and normal operation of human blood. Studies have found that fibrinolytic substances also have many new physiological functions. Such as plasminogen has the ability to inhibit the proliferation of vascular endothelial cells; PAIS interaction with t-PA, homeostasis balance trophoblast cells immersed in the uterine wall, villus space villus sinus fibrinolytic and other important physiological processes; PAI - 1 may promote the growth of tumor cells by inhibiting the apoptosis of tumor cells, which is a series of ominous prognostic factors when tumors develop. Therefore, further understanding of the function of fibrinolytic material is necessary
