摘要
目的:研究护心康对My D88和TRAF6的影响,探讨其抗动脉粥样硬化的机制。方法:采用雄性中国本兔14只,随机分为正常组和护心康组,分别以蒸馏水和护心康连续灌胃7 d,末次灌胃给药2 h后心脏采血分离血清。体外培养人脐静脉内皮细胞,随机分为3组:正常组,模型组,护心康组。用LPS刺激2 h后,模型组给予空白血清,护心康组给予含药血清干预24 h,收集细胞,用荧光定量PCR和Western blot分别测定My D88和TRAF6m RNA的表达。结果:LPS刺激引起My D88和TRAF6基因表达升高(P<0.01);护心康组表达较模型组低(P<0.05)。结论:护心康具有降低内皮细胞My D88和TRAF6基因表达的作用,其抗动脉粥样硬化的作用可能与此有关。
Objective： To explore the mechanism of Huxinkang on atherosclerosis rabbit induced by MyD88 and TRAF-6. Method： The 14 male Chinese white rabbits were randomly divided into 2 groups： the normal group and the Huxinkang group. Distilled water was given to the normal group, and Huxinkang was given to the Huxinkang group for 7 days. The blood was withdrawn from the heart 2 h after the last gastrogavage. The serum was isolated after centdfuge. Human umbilical vein endothe- lial cell （HUVECS） was cultured and then randomly divided into 3 groups： the normal control group, the model group and the Huxinkang group. HUVECs were stimulated with LPS for 2 h, and then treated with blank serum and Huxinkang contained serum. HUVECs were collected 24 h later. The gene expressions of MyD88 and TRAF-6 were detected by fluorescent quantita- tive PCR. Results： HUVECS were stimulated by LPS, the expressions of MyD88 and TRAF-6 were enhanced, showing statisticaI differrence when compared with the vehicle centrel group （P〈0.01）. Huxinkang contained serum significantly decreased the higher expression of MyDe88 and TRAF-6, showing statistical difference when compared with the model group （P〈0.05）. Conclusions： Huxinkang could inhibit MyDe88 and TRAF-6TLR. This might be one of the mechanisms for preventing atherosclerosis.
