摘    要:目的:观察沙利度胺局部给药对大鼠颈动脉损伤后新生内膜形成和血管再狭窄的影响,并探讨其可能机制。方法:48只SD大鼠随机分成假手术组(A组)、单纯手术组(B组)和沙利度胺组(C组),A组仅分离和结扎右颈外动脉,B组和C组行右颈总动脉血管成形术,C组在损伤血管局部给予沙利度胺。在术后7d和14d分别测定血清中血管内皮生长因子(VEGF)和肿瘤坏死因子(TNF)-α水平、观察血管内膜损伤后形态学变化、用免疫组织化学法观察组织VEGF和巨噬细胞表达水平。结果:在血管损伤后14d,B组VEGF和TNF-α水平明显高于A组和C组(P〈0.01),B组管腔面积明显缩小(P〈0.01),而新生内膜面积明显增加(P〈0.01),同时B组血管内膜VEGF和巨噬细胞的表达亦较A组和B组增加(P〈0.01)。结论:沙利度胺局部给药可抑制血管损伤后新生内膜形成和血管再狭窄的发生。

关 键 词:沙利度胺  血管内皮生长因子  内膜增生  再狭窄

Abstract:Objective:To determine the inhibitory effect of locally delivered thalidomide on neointimal hyperplasia and restenosis after balloon injury in rat carotid artery and the possible mechanisms.Methods:48 male Sprague-Dawley rats were randomly divided into sham operation group(group A),operation group(group B)and operation with thalidomide group(group C).The carotid arteries of group B and group C were injured by conventional percutaneous transluminal coronary angioplasty(PTCA)balloon catheter.At 7 and 14 days ...
Keywords:thalidomide  vascular endothelial growth factor  neointimal hyperplasia  restenosis
