摘要:

摘要:目的 建立急性心肌梗死 (AMI) 大鼠血清代谢轮廓模型, 探寻对 AMI 预后及并发症具有临床治疗价值的
特征代谢物。方法 选取健康雄性 Wistar 大鼠 20 只, 随机平均分为对照组和 AMI 1 周组。AMI 1 周组进行冠状动
脉前降支结扎, 建立 AMI 模型, 1 周后心脏取血处死。利用代谢组学研究平台对大鼠的血液样本进行代谢轮廓分
析, 建立大鼠 AMI 后血液的正交偏最小二乘判别模型及主成分分析模型, 结合 SPSS 19.0 软件的数据处理最终得到
特征代谢产物。结果 成功建立了主成分分析模型及正交偏最小二乘判别模型, 同时从模型中筛选并鉴定了 27
AMI 1 周组与对照组具有差异的特征代谢物, 在这 27 种特征代谢物中溶血磷脂酰胆碱、 溶血磷脂酰乙醇胺等差
异明显。结论 构建的代谢轮廓模型很好地拟合了 AMI 后期大鼠机体的代谢紊乱状态, 筛选出的特征代谢产物可
为该疾病治疗以及并发症的预防等提供参考和帮助。

Abstract: Abstract: Objective A serum metabolic profiling in acute myocardial infarction (AMI) rat was established to screen
potential metabolic markers of AMI prognosis and complication. Methods Male Wistar ratsn=20were divided randomly
into AMI 1 week group and control group. Anterior descending coronary was ligated in rats in AMI 1 week group to establish
AMI model. After one week, these rats were sacrificed and the blood was collected from heart. And metabolomics platform
was used to analyze serum metabolic profile. After PCA (principal component analysis) and OPLS-DA (Orthogonal partial
least squares - Discriminant Analysis) were established, SPSS 19.0 was used to analysis data to get the potential metabolic
markers. Results The PCA and OPLS-DA were established successfully and 27 metabolites present differently in levels
between AMI 1 week group and the control group. Among these metabolites, LysoPC (lysophosphatidylcholine) and LysoPE
(lysophosphatidyl ethanolamine) demonstrate significant differeance between these two groups. Conclusion The metabolic
disorder in AMI patients can be reflected from the serum metabolic profiling. And these significant metabolites provide sup⁃
port and reference for the prevention of AMI complication and its treatment.
