摘要目的：探讨瑞舒伐他汀（Rosu）对同型半胱氨酸（Hcy）损伤人脐静脉内皮细胞（HUVECs）血管细胞间黏附分子－1（VCAM－1）表达的影响。方法原代培养HUVECs，2～3代进行试验，MTT实验设立空白对照组、Hcy（0.2～1.2 mmol／L）组、Rosu（0.5、1.0、2.0和5.0 mmol／L）组，实验组：Rosu 1.0 mmol／L和2.0 mmol／L进行预处理细胞，2 h后加入0.6 mmol／L浓度的Hcy损伤HUVECs，Real time PCR法测定VCAM－1 mRNA表达，Western blot法测定细胞VCAM－1蛋白含量；Rosu 2.0 mmol／L＋甲羟戊酸（ Mev ）100μmol／L预处理2 h后再加入0.6 mmol／L浓度的Hcy以了解Mev对VCAM－1蛋白表达的影响。结果 Hcy组VCAM－1蛋白和mRNA表达较空白对照组明显增强（P＜0.05）；Rosu组VCAM－1蛋白和mRNA表达较Hcy组明显减弱（P＜0.05），且Mev不能阻断Rosu的这种作用。结论 Rosu可通过抑制HUVECs表达VCAM－1产生抗炎作用，且这种作用独立于其调脂作用。
