摘要 目的观察Th17/白细胞介素(IL)-17对兔动脉粥样硬化形成的影响。方法通过导管球囊损伤动脉血管加高脂饲养的方法建立兔动脉粥样硬化模型。22只新西兰大白兔随机分为正常对照组、高脂组、贝那普利组。饲养12 w后,检查兔动脉粥样斑块的大小、血脂水平、血浆血管紧张素(Ang)Ⅱ、IL-17、超敏C-反应蛋白(hs-CRP)水平。结果成功建立起兔动脉粥样硬化模型;高脂组、贝那普利组总胆固醇(TC)、低密度脂蛋白胆固醇(LDL-C)、极低密度脂蛋白胆固醇(VLDL-C)及血浆AngⅡ、IL-17、hs-CRP表达水平明显高于正常对照组(P<0.05);贝那普利组血浆AngⅡ、IL-17、hs-CRP表达水平明显低于高脂组(P<0.05),血脂水平(TC、LDL-C、VLDL-C)表达没有差异(P>0.05),血浆AngⅡ与IL-17水平呈正相关(P<0.05),血浆IL-17与hs-CRP水平呈正相关(P<0.05)。结论 AngⅡ会促使动脉粥样硬化的形成,其一个机制可能为AngⅡ上调Th17/IL-17表达,Th17/IL-17可能通过引起和加剧机体炎症反应参与动脉粥样硬化的发生、发展。
