摘要 目的探讨高血压合并颈动脉硬化患者外周血高迁移率族蛋白B1(HMGB1)和Toll样受体4(TLR4)表达变化及其与IL-17、IL-6水平的相关性。方法选取高血压合并颈动脉硬化组79例、单纯高血压组74例、健康体检对照组90例。采用颈动脉超声测量颈动脉内-中膜厚度(IMT),采用酶联免疫吸附试验检测血清HMGB1和TLR4水平,流式细胞仪测定各组外周血单核细胞HMGB1和TLR4蛋白表达水平。结果对照组、单纯高血压组、高血压合并颈动脉硬化组患者IMT分别为(0.87±0.07)、(0.98±0.06)、(1.23±0.14)mm。高血压合并颈动脉硬化组患者IMT均大于单纯高血压组和对照组(P均<0.05)。高血压合并颈动脉硬化组较单纯高血压组和对照组血清HMGB1、TLR4、IL-17、IL-6水平及外周血单核细胞HMGB1和ILR4蛋白表达水平均增高(P均<0.05)。血清HMGB1、TLR4表达与IL-17、IL-6浓度呈正相关(P均<0.05)。结论高血压合患者外周血HMGB1、TLR4表达上调,促使炎症因子分泌增加,导致高血压颈动脉硬化的形成。
