摘要 目的:研究B1激肽受体在人颈动脉粥样硬化斑块中的表达变化,以探讨其在粥样斑块形成中的可能作用机制。方法:收集40例因颈动脉粥样硬化狭窄(﹥70%)行颈动脉内膜剥脱术患者(斑块组)的手术标本,并依据术前症状分为无症状斑块组(n=15)和有症状斑块组(n=25),另收集人肠系膜动脉标本作为对照组(n=15)。采用半定量逆转录聚合酶链式反应技术(RT-PCR)测定各组B1激肽受体mRNA表达水平,采用Western blot检测其B1激肽受体蛋白的表达水平。结果:斑块组B1激肽受体mRNA及其蛋白表达水平较对照组均显著上调,差异有统计学意义(P<0.05);有症状斑块组B1激肽受体mRNA及蛋白表达水平较无症状斑块组均显著上调,差异有统计学意义(P<0.05)。结论:B1激肽受体与人颈动脉粥样硬化斑块的形成和稳定性密切相关。
