摘 要:目的探究柴胡陷胸汤含药血清对高脂血清致人脐静脉内皮细胞ECV304损伤的影响及机制。方法制备高脂血清和柴胡陷胸汤含药血清。以高脂血清诱导ECV304细胞损伤,并以低、中、高浓度(3.47、6.94、13.88 g/kg,以生药量计)的柴胡陷胸汤含药血清进行干预,检测各组细胞增殖率和细胞上清液中相关炎症因子[肿瘤坏死因子α(TNF-α)、白细胞介素6(IL-6)]、血管内皮功能指标[内皮型一氧化氮合酶(eNOS)、一氧化氮(NO)、内皮素1(ET-1)]水平,检测细胞中细胞间黏附分子1(ICAM-1)、转化生长因子β1(TGF-β1)mRNA的表达水平以及Toll样受体4(TLR4)、核因子κB抑制因子α(IκBα)、磷酸化IκBα(p-IκBα)蛋白的表达水平和磷酸化核因子κB p65(p-NF-κB p65)/NF-κB p65比值。结果与对照组比较,模型组细胞增殖率,TNF-α、IL-6、ET-1水平,ICAM-1 mRNA表达水平,TLR4、p-IκBα蛋白表达水平和p-NF-κB p65/NF-κB p65比值均显著升高(P<0.05),eNOS、NO水平,TGF-β1mRNA表达水平和IκBα蛋白表达水平均显著降低(P<0.05);与模型组比较,柴胡陷胸汤低、中、高浓度组上述指标均显著好转(P<0.05),且柴胡陷胸汤高浓度组显著优于柴胡陷胸汤低、中浓度组(P<0.05)。结论柴胡陷胸汤可改善高脂血清诱导的血管内皮细胞损伤,其作用机制可能与降低炎症因子水平、抑制TRL4/NF-κB通路活化有关。OBJECTIVE To explore the effects of Chaihu xianxiong decoction containing serum on human umbilical vein endothelial cells ECV304 injury induced by high-fat serum and its mechanism.METHODS The high-fat serum and Chaihu xianxiong decoction containing serum were prepared.ECV304 injury was induced by high-fat serum,and the intervention experiments were conducted with low-concentration,medium-concentration and high-concentration(3.47,6.94,13.88 g/kg,by crude drug)of Chaihu xianxiong decoction containing serum.The proliferation rate,the levels of related inflammatory factors[tumor necrosis factor-α(TNF-α),interleukin-6(IL-6)]and vascular endothelial function indexes[endothelial nitric oxide synthase(eNOS),nitric oxide(NO)and endothelin-1(ET-1)]were all detected in each group.mRNA expressions of intercellular adhesion molecule-1(ICAM-1)and transforming growth factor-β1(TGF-β1)were detected,and the expression of Toll-like receptor 4(TLR4),nuclear factor-κB inhibitorα(IκBα),phosphorylated IκBα(p-IκBα)protein and the ratio of phosphorylated nuclear factor-κB p65(p-NF-κB p65)to NF-κB p65 were also detected.RESULTS Compared with control group,the proliferation rate of cell,the levels of TNF-α,IL-6 and ET-1,m RNA expression of ICAM-1,protein expressions of TLR4 and p-IκBαand p-NF-κB p65/NF-κB p65 ratio were significantly increased in the model group(P<0.05);the levels of eNOS and NO,mRNA expression of TGF-β1 and protein expression of IκBαwere significantly decreased(P<0.05).Compared with model group,above indexes were all reversed significantly in low-concentration,medium-concentration and high-concentration groups of Chaihu xianxiong decoction(P<0.05),while the Chaihu xianxiong decoction high-concentration group were all better than low-concentration and medium-concentration groups(P<0.05).CONCLUSIONS Chaihu xianxiong decoction can improve endothelial cell injury induced by high-fat serum.Its mechanism of action may be associated with reducing the levels of inflammatory factors and inhibiting the activ
