摘要 目的本实验研究探讨,阿托伐他汀早期干预由脱氢野百合碱诱导肺动脉高压的比格犬的作用及其可能的机制。方法分组:阿托伐他汀组n=7(2mg/kg野百合碱+2mg/kg阿托伐他汀);野百合碱组n=5(2mg/kg野百合碱组+安慰剂);正常对照组n=6(溶剂0.1ml/kg二甲基酰胺组+安慰剂);药物干预前和干预8周后测量血流动力学参数,用免疫组织化学染色法检测肺小动脉半胱氨酸天冬氨酸蛋白酶-3(Caspase-3)、平滑肌肌动蛋白(α-smooth muscle actin,α-SMA)蛋白表达;用实时定量PCR法检测各组肺组织内皮型一氧化氮合酶(eNOS)、内皮素前体-1(preproET-1)、白介素-1β(IL-1β)、肿瘤坏死因子-α(TNF-α)、血管内皮生长因子(VEGF)mRNA表达。结果阿托伐他汀组犬的肺动脉压力,右心室收缩压,肺动脉收缩压,肺血管阻力较野百合碱组明显下降(P<0.05),而心输出量明显升高(P<0.05),并接近正常对照组。肺组织preproET-1mRNA、IL-1βmRNA、TNF-αmRNA、VEGF mRNA转录水平在阿托伐他汀组显著低于野百合碱组(P<0.05);eNOS mRNA转录水平在阿托伐他汀组显著高于野百合碱组(P<0.05)。结论脱氢野百合碱可诱导犬形成肺动脉高压;阿托伐他汀药物早期干预能降低肺动脉高压,降低血管内膜增生,抑制炎症因子产生;抑制缩血管物质合成;逆转肺血管重构的发生,诱导平滑肌细胞凋亡。 Backgrounds: Pulmonary arterial hypertension (PAH) is a life-threatening disease characterized by marked and sustained elevation of pulmonary hypertension. Atorvastatin which is a 3-hydroxy-3-methylglutaryl CoA (HMG-CoA) reductase inhibitor has been shown to attenuate chronic hypoxic pulmonary hypertension. Our study was to assess whether atorvastatin is capable of attenuating dehydromonocrotaline(DHMC)induced pulmonary hypertension in beagles and explore potential mechanisms of statin effect. Methods: DHMC...
