Methods: Salt-sensitive(Dahl/SS) rats were fed with normal diet(0.3% Na Cl) and the high-salt diet(8% Na Cl) to observe the changes in blood pressure and heart function, as the control group and the model group. Salt-insensitive rats(SS-13BN) were fed with the high-salt diet(8% Na Cl) as the negative control group. After modeling, the model rats were randomly divided into heart failure(HF) group, Shenmai Injection(SMI) group and pirfenidone(PFD) group by a random number table, with 6 rats in each group. They were given sterilized water, SMI and pirfenidone, respectively. Blood pressure, cardiac function, fibrosis and related molecular expression were detected by sphygmomanometer, echocardiogram, enzyme linked immunosorbent assay(ELISA),hematoxylin-eosin staining, Masson staining, immunofluorescence and qPCR analysis. Results: After high-salt feeding, compared with the control and negative control group, in the model group the blood pressure increased significantly, the left ventricular ejection fraction(LVEF) and left ventricular fraction shortening(LVFS) were significantly reduced, and the serum NT-pro BNP concentration increased significantly(all P<0.05);furthermore,the arrangement of myocardial cells was disordered, the edema was severe, and the degree of myocardial fibrosis was also significantly increased(P<0.05);the protein and m RNA expressions of collagen type Ⅰ(Col Ⅰ) were up-regulated(P<0.05), and the mRNA expressions of transforming growth factor β1(TGF-β1), Smad2 and Smad3 were significantly up-regulated(P<0.05). Compared with HF group, after intervention of Shenmai Injection, LVEF and LVFS increased, myocardial morphology was improved, collagen volume fraction decreased significantly(P<0.05), and the mRNA expressions of Col Ⅰ, TGF-β1, Smad2 and Smad3, as well as Col Ⅰprotein expression, were all significantly down-regulated(all P<0.05). Conclusion: Myocardial fibrosis is the main pathological manifestation of hypertensive heart failure, and Shenmai Injection could inhibit myocardial fibrosis and effectively improve heart failure by regulating TGF-β1/Smad signaling pathway.展开更多
文摘目的:研究参麦注射液对高血压心衰大鼠粪便代谢组学的影响。方法:20只Dahl盐敏感大鼠随机分为正常组(6只)、模型组(7只)和参麦注射液组(7只),以高盐饲料(8%NaCl浓度)喂养模型组、参麦注射液组大鼠20周建立高血压心衰模型。给药15 d后收集各组粪便样本,运用基于液相色谱-质谱(liquid chromatography mass spectrometry,LC-MS)联用的代谢组学技术进行研究。结果:主成分分析、偏最小二乘判别分析得分图显示,3组大鼠的代谢模式存在显著差异,与模型组比较参麦注射液组神经氨酸、别石胆酸、丙氨酰色氨酸、3,9-十六碳二烯酸、N-棕榈酰酪氨酸、亚油基肉碱、3-羟基-顺式-5-十四碳酰肉碱表达水平回调。结论:参麦注射液干预高血压心衰的机制涉及优化氨基酸代谢、蛋白质代谢、肉碱代谢、胆汁酸代谢、脂质代谢等多个层面。
