摘要
目的:研究瑞舒伐他汀对内皮细胞功能变化的影响。方法:选择2013年6月-2014年6月我院健康体检者15例,冠心病患者30例。分成健康对照组、冠心病药物干预组、冠心病组,各15例。对比各组不对称二甲基精氨酸(ADMA)、一氧化氮(NO)及一氧化氮合酶(NOS)的血液酶联免疫吸附测定(ELISA)检测结果,分析酶标仪光密度(OD)值与其相关性;对人脐静脉内皮细胞(HUVEC)培养4 h及8 h后,根据瑞舒伐他汀的浓度剂量分成5个组,即0μmol/L对照组和0.1、1、10、100μmol/L组,检测不同浓度瑞舒伐他汀对内皮细胞二甲基精氢酸二甲胺水解酶(DDAH)信使核糖核酸(m RNA)的表达变化。结果:冠心病药物干预组的ADMA水平均显著低于冠心病组,但仍高于健康对照组;NO及NOS水平均显著高于冠心病组,但仍低于健康对照组,差异均有统计学意义(P<0.05)。根据Pearson法分析相关性可知,酶标仪OD值与ADMA、NO及NOS均呈正相关。HUVEC细胞培养4 h后的逆转录-聚合酶链反应(RT-PCR)结果显示,0.1、1、10及100μmol/L瑞舒伐他汀组的DDAH m RNA表达均上升,且10μmol/L及100μmol/L瑞舒伐他汀组的DDAH m RNA表达较对照组的差异有统计学意义(P<0.05)。培养8 h后的RT-PCR结果显示,0.1、1、10及100μmol/L瑞舒伐他汀组的DDAH m RNA表达均上升,且10μmol/L瑞舒伐他汀组的DDAH m RNA表达较对照组的差异有统计学意义(P<0.05)。结论:瑞舒伐他汀对内皮细胞具有较好的保护作用,值得临床关注与重视。
OBJECTIVE：To study and analyze the impact of rosuvastatin on function changes of endothelial cell. METHODS：30 patients with coronary heart disease were selected from our hospital during Jun. 2013 to Jun. 2014,and 15 healthy persons were included. They were divided into healthy control group,drug intervention of coronary heart disease group and coronary heart disease group with 15 cases in each group. The levels of asymmetric dimethylarginine（ADMA）,NO and nitric oxide synthase（NOS）were determined by ELISA and compared among those groups. Its relationship with OD value was analyzed. After cultured for 4 h and 8 h,human umbilical vein endothelial cells（HUVEC）were divided into 5 groups,i.g. control group 0 μmol/L,0.1 μmol/L group,1 μmol/L group,10 μmol/L group,100 μmol/L group. The change of DDAH m RNA expression in endothelial cells treated with different concentrations of rosuvastatin was detected. RESULTS：The level of ADMA in drug intervention of coronary heart disease group were significantly lower than in coronary heart disease group,but still higher than that in healthy control group;NO and NOS levels were significantly higher than coronary heart disease group,but still lower than healthy control group,with statistical significance（P〈0.05）. According to Pearson method correlation analysis,OD value was positively correlated to ADMA,NO and NOS. 4h after HUVEC culture,RT-PCR showed that m RNA expression of DDAH were increased in 0.1 μmol/L,1 μmol/L,10 μmol/L and 100 μmol/L rosuvastatin groups,there was statistically significant difference between 10 μmol/L and 100 μmol/L rosuvastatin groups and control group（P〈0.05）. 8 h after HUVEC culture,RT-PCR showed m RNA expression of DDAH were increased in 0.1 μmol/L,1 μmol/L,10 μmol/L and 100 μmol/L rosuvastatin groups,and there was statistically significant difference between 10 μmol/L rosuvastatin group and control group（P〈0.05）. CONCLUSIONS：Rosuvastatin is a new type of lipid-lowering drugs,which has a good protective effect on endothelial cells,it is worthy of attention in the clinic.
