摘要: 目的 观察心可舒及氟伐他汀对兔动脉粥样硬化(AS)斑块血管细胞黏附分子(VCAM-1)的影响及其机制。方法 将雄性新西兰大白兔随机分为对照组、高脂AS模型组、氟伐他汀组及心可舒组,每组9只。通过HE染色评估粥样斑块的程度。应用免疫组化检测巨噬细胞、基质金属蛋白酶9(MMP-9)和α-平滑肌肌动蛋白(α-SMA)的表达,蛋白免疫印迹法分析斑块VCAM-1的表达水平,并检测氧自由基SOD及MDA的含量。结果:心可舒及氟伐他汀组VCAM-1的表达明显低于高脂组的水平(P<0.01),巨噬细胞、MMP-9及α-SMA的水平亦明显低于高脂组(P<0.01),SOD的含量明显升高(P<0.01)。结论:心可舒及氟伐他汀通过抗氧自由基及抗炎作用保护兔血管内皮及抗动脉粥样硬化。

Abstract: Objective: To observe the effect of Xinkeshu (XKS) and fluvastatin on adhesive molecules and inflammationin in plaque of atherosclerosis in rabbit.Methods: The New Zealand white rabbits were randomly divided into four groups: control group, high-fat group, fluvastatin group and Xinkeshu(XKS) group (9 /per group).The atherosclerotic plaques were evaluated by HE staining. Expression of MMP-9,macrophage andα-SMA in atherosclerotic plaques were detected by immunohistochemistry. The SOD and MDA were also measured. Results:Compared with high-fat group,the expressions of VCAM-1 in atherosclerotic plaques significantly decreased with the treatment of XKS and fluvastatin(P<0.01). The expression of MMP-9,macrophage infiltration andα-SMA were also lower in the XKS group and fluvastatin group than that in high-fat group (P<0.01),while serum SOD activity increased (P<0.01). Conclusions: XKS and fluvastatin play an important role in the protection of endothelial function and anti-atherosclerosis effect by its anti-inflammatory and anti-oxygen radical.
