摘要
采用左冠状动脉前降支结扎的方法,建立SD大鼠急性心肌梗死(Acute myocardial infarction,AMI)模型,使用超高效液相色谱-串联四极杆/飞行时间质谱(UPLC-QTOF/MS)代谢组学研究平台对大鼠血浆样本进行代谢轮廓分析,研究复方丹参滴丸对AMI大鼠心肌保护作用机制。经主成分分析和偏最小二乘法分析,筛选并鉴定出22种与AMI相关的差异代谢物,其中的8种能够被复方丹参滴丸显著调节,分别是硫酸对甲苯、马尿酸、雌马酚葡萄糖苷酸、溶血磷脂胆碱(16∶0)、胆酸、油酸酰胺、棕榈酰胺和鞘脂(d18∶1/16∶0)。研究结果表明,复方丹参滴丸可能是通过调节苯丙氨酸代谢、甘油磷脂代谢、脂肪酸代谢、胆汁酸代谢及鞘脂代谢通路,发挥抗AMI大鼠心肌损伤的作用。
An acute myocardial infarction rat model was established by ligation of the left ventricular coronary artery. Plasma samples of rats were collected and analyzed by ultra performance liquid chromatography coupled with quadrupole time- of-flight mass spectrometry （ UPLC- QTOF/MS） to study the myocardial protection mechanism of compound Danshen dropping pill （ CDDP）. After principal component analysis （PCA） and partial least squares discriminant analysis （PLS-DA） , 22 metabolites were identified as potential biomarker of AMI. Furthermore, CDDP had remarkable effect on AMI rats. p-Tolyl sulfate,hippuric acid, equol 7-O- glucuronide, lysoPC（16：0） , cholic acid, oleamide, palmitic amide and SM（d18：1/16：0） were significantly changed in treatment group. The results showed that CDDP had a very good myocardial protection effect on AMI rats, and might influence the pathways of phenylalanine metabolism, glycerophospholipid metabolism, fatty acid metabolism, primary bile acid biosynthesis and Sphingolipid metabolism.
