摘　　要：【目的】探讨益气活血片对人工寒潮促发脑卒中大鼠凝血和纤溶系统的影响。【方法】选用SD大鼠,随机分为4组,按照双肾双夹法复制易卒中型肾血管性高血压大鼠模型,中药组给予益气活血片(剂量为1.89 g·kg-1·d-1),阳性对照组给予阿司匹林(剂量为80 mg·kg-1·d-1),模型组及空白对照组给予等容积蒸馏水,从高血压模型复制术后14 d开始,每天1次,直到112 d后置于人工寒潮箱中3 d诱发卒中,取血检测血浆凝血酶激活的纤溶抑制物(TAFI)、蛋白C(PC)、凝血酶—抗凝血酶复合物(TAT)及纤溶酶(PAP)水平。【结果】与模型组比较,益气活血片组可显著降低血浆TAFI、PC、TAT、PAP水平,差异均有统计学意义(P<0.05)。【结论】益气活血片对脑卒中的防治作用与其能改善凝血和纤溶系统的平衡状态有关。Objective To study the effect of Yiqi Huoxue Tablets on blood coagulation and fibrinolysis system of rats with cerebral apoplexy induced by artificial cold wave. Methods SD rats were randomized into 4 groups. The apoplexy-prone renovascular hypertensive rat model was established by the bilateral renal arteries clamping method.From the 14 th day after the modeling operation, the treatment group was given Yiqi Huoxue Tablets（1.89 g·kg-1·d-1）,the positive control group was given aspirin（80 mg·kg-1·d-1）, and the model group and the blank group were given the same volume of distilled water, once a day. After 112 days, the rats were put into the artificial cold wave box staying for 3 days to inducing apoplexy, and then thrombin-activatable fibrinolysis inhibitor（TAFI） and protein C（PC）, thrombin-antithrombin complexes（TAT） and plasmin-antiplasmin（PAP） levels were measured. Results The plasma levels of TAFI, PC, TAT, and PAP in Yiqi Huoxue Tablets group were lower than the model group,the difference being statistically significant（P〈0.05）. Conclusion The preventive and therapeutic mechanism of Yiqi Huoxue Tablets for cerebral apoplexy is probably related with the regulation of the balance between blood coagulation and fibrinolytic system of apoplexy-prone renovascular hypertensive rats.
