摘要 目的观察茵陈五苓散对动脉粥样硬化(AS)大鼠血管平滑肌细胞(VSMC)c-mycmRNA表达的影响。方法70只雄性Wistar大鼠随机分为正常组、模型组、茵陈五苓散组、胶股蓝组,采用高脂饲料喂饲法复制大鼠动脉粥样硬化模型,造模一月后抽样检测大鼠主动脉,以发现动脉粥样硬化斑块为造模成功指标,治疗一个月后分别检测血脂、血液流变学,用HE染色观察主动脉组织学变化,用透射电镜观察大鼠主动脉组织超微结构变化,用RT-PCR技术检测大鼠VSMC基因c-mycmRNA的表达。结果茵陈五苓散与胶股蓝组比较,降低TC、TG、LDL,升高HDL均显著(P<0.01),降低血浆黏度、全血中切、红细胞压积、血小板黏附率明显(P<0.01或P<0.05),维持主动脉组织结构,下调基因c-mycmRNA的表达(P<0.05)。结论茵陈五苓散具有良好的抗动脉粥样硬化作用,其调整相关基因c-mycmRNA的表达可能是其治疗的分子机理。 Objective To observe the effect of Yinchenwulin(YCWL) powder on the c-myc rnRNA expression in vascular smooth muscle cell (VSMC) of atherosclerosis(AS) rats. Methods 70 Wistar rats were randomly divided into four groups: normal, model, Gypenosides treatment and YCWL powder treatment groups. AS models of rats were set up by feeding with high fat diet for one month. One month after treatment the level of serum lipid and blood rheology were measured, the phathological change of aorta was observed by HE staining, the ultrastructure change of aorta was observed by transmission electronic microscope, and c-myc mRNA expression in VSMC was detected by RT-PCR. Results Compared with Gypenosides treatment, YCWL powder could obviously decreased the levels of serum TC,TG and LDL, increase serum HDL level, reduce plasma viscosity,whole blood mid-cut,hematocrit and platelet adhesion rate, maintain aorta tissue structure, and down-regulate c-myc mRNA expression. Conclusion YCWL powder has therapeutic effect for atherosclerosis by regulating c-myc mRNA expression.
