| 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、13.88g/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β（1TGF-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κBp65（p-NF-κBp65）/NF-κBp65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-1mRNA表达水平，TLR4、p-IκBα蛋白表达水平和p-NF-κBp65/NF-κBp65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。 |
| ABSTRACT： | OBJECTIVE To explore the effects of Chaihu xianxiong decoction containing serum on human umbilical vein endothelial cells ECV 304 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 inhibitor α（IκBα），phosphorylated I κBα（p-IκBα）protein and the ratio of phosphorylated nuclear factor-κB p 65（p-NF-κB p 65）to NF -κB p 65 were also detected . RESULTS Compared with control group ，the proliferation rate of cell，the levels of TNF -α，IL-6 and ET -1，mRNA expression of ICAM -1，protein expressions of TLR 4 and p -IκBα and p -NF-κB p65/NF-κB p 65 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 I κBα were 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 activation of TLR 4/NF-κB signaling pathway . |
