摘要：

目的:探讨辛伐他汀(simvastatin,SIM)对大鼠脑出血后Toll样受体4(toll-like receptor 4,TLR4)介导的脑内炎症损伤的干预作用。方法:采用注入自体血方法复制脑出血(intralerebral hemorrhage,ICH)模型,随机分为假手术组、模型组和干预组。Garcia等方法进行神经功能障碍评分;干湿重法检测脑组织含水量;免疫组化SP法检测TLR4和IL-1β蛋白的表达;免疫印迹检测TLR4和IL-1β蛋白的表达水平。结果:与假手术组比较,ICH模型组脑组织含水量明显升高(P<0.05),TLR4和IL-1β蛋白的表达明显增加(P<0.05);辛伐他汀干预后,TLR4表达量下降,IL-1β蛋白的表达及脑含水量明显下调,与脑神经功能障碍评分上调相一致。结论:大鼠脑出血后引起出血周围脑组织炎症损伤,辛伐他汀可能通过减轻TLR4介导的炎症损伤,改善神经功能恢复,起到神经保护作用。
