摘要:

目的:观察通心络对主动脉粥样硬化家兔血清和动脉粥样硬化(AS)局部纤溶酶原激活物抑制物-1(PAI-1)及血管细胞黏附分子-1(VCAM-1)表达的影响,阐明通心络抗AS的可能机制。方法:24只大耳白兔随机分为常规饲料组、胆固醇饲料组和通心络组,饲养14周,检测实验前后血清胆固醇(TC)、甘油三酯(TG)、低密度脂蛋白(LDL)、PAI-1、VCAM-1水平的变化;处死动物后取主动脉进行病理学检查;采用免疫组织化学方法测定AS局部PAI-1和VCAM-1阳性表达百分数。结果:实验前三组动物血清TC、TG、LDL、PAI-1和VCAM-1水平比较差异无显著性(P>0.05),14周后胆固醇饲料组和通心络组TC、TG、LDL、PAI-1和VCAM-1水平明显高于对照组(P<0.01),通心络组血清TC、TG、LDL、PAI-1和VCAM-1水平明显低于胆固醇饲料组 (P<0.01);免疫组织化学检测胆固醇饲料组和通心络组AS局部PAI-1和VCAM-1的阳性表达百分数明显高于对照组(P<0.01),通心络组PAI-1和VCAM-1的阳性表达较胆固醇饲料组的表达明显减少(P<0.01)。结论:AS的发生伴有PAI-1和VCAM-1的过度表达,抑制PAI-1和VCAM-1的表达可能是通心络抗AS机制之一。

Abstract:

Abstract:Objective  To observe the effect of Tongxinluo on the expreeions of plasminogen activator inhibitor type-1 (PAI-1) and vascular cell adhension molecule-1 (VCAM-1) in rabbits with atherosclerosis(AS),and explore the possible mechanism.Methods Twenty four rabbits were randomly divided into control,cholesterol diet,and Tongxinluo groups.The levels of serum cholesterol(TC),triacylglycerol(TG),low density lipoprotein(LDL),PAI-1 and VCAM-1 were measured before and after treatment.The aortas were harvested for pathologic morphological observation.Immunohistochemistry analysis was used to evaluate the positive percentages of  PAI-1 and VCAM-1.Results There were no differences of TC,TG,LDL,PAI-1 and VCAM-1 between three groups before treatment (P>0.05). 14 weeks after treatment,the TC,TG,LDL,PAI-1 and VCAM-1 levels in cholesterol diet group and Tongxinluo group were significantly higher than those in control group(P<0.01),while the TC,TG,LDL,PAI-1and VCAM-1 levels in Tongxinluo groups were signficantly lower than those in cholesterol diet group(P<0.01). The expressions of  PAI-1 and VCAM-1 in aorta in cholesterol diet and Tongxinluo group were higher than those in control group(P<0.01),and the expressions of PAI-1 and VCAM-1     in Tongxinluo group  were lower than those in cholesterol group(P<0.01).Conclusion PAI-1and VCAM-1 over express   in   AS rabbits,while inhibiting the expressions of PAI-1 and VCAM is likely to be one of anti-AS  mechanism of  Tongxinluo.
