目的:对急性心肌梗死( AMI)患者血浆代谢谱进行分析,寻找血小板激活后释放的特征代谢物。方法病例对照研究。收集2012年8月至2013年2月天津市第三中心医院临床确诊的AMI患者25例为AMI组(X组),男14名,女11名,平均年龄(67±13)。同期健康体检者29名为对照组,男11名,女18名,平均年龄(65±12)岁,且对照组血浆经提取血小板后按是否用胶原激活血小板再分为健康对照组(A组)和血小板激活组(B 组),3组分别采用超高效液相色谱与质谱联用( UPLC-MS)代谢组学研究平台对血清代谢谱分析,通过构建主成分分析( PCA)和正交偏最小二乘判别分析( OPLS-DA)模型,然后利用独立样本非参数检验,A、B组筛选出血小板激活的特征代谢物,再与X组比较寻找共性物质。结果经过数据库搜索和结构推导,A、B组共筛选出20个特征代谢物,其中3种不同的溶血磷脂酰胆碱、1-磷酸鞘氨醇、二十二碳六烯乙醇酰胺、鞘氨醇磷酸胆碱、凝血恶烷和14-甲基十六烷酸在B组与AMI组有相同变化趋势并与对照组间具有显著差异的特征代谢物。结论用代谢谱分析方法筛选出的特征离子有很好的区分AMI患者与健康人群的能力,对AMI早期诊断有很强指示作用。(中华检验医学杂志,2015,38:325-328)

Objective To identity the characteristic metabolites of platelets activation by Plasma metabolic Profiling in acute myocardium infarction ( AMI ) patients.Methods From August 2012 to February 2013, samples in three groups were collected at Tianjin Third Central hospital, including AMI group (25 clinically diagnosis myocardial infarction, 14 male, 11 female, average age 67 ±13 ) , control group(A) and simulation platelet activation group(B) (A and B group composed of 29 health volunteers, 11 male 18 female, average age 65 ±12 ) .After collagen platelet activation on B group, HPLC-LTQ Orbitrap XL MS platform was used to analyze the serum metabolic profiling in three groups respectively.Principal component analysis ( PCA) model and partial least squares-discriiminate analysis ( OPLS-DA) model were established to select characteristic metabolites in A and B group, and then tested in X group to find common ions.Results 20 characteristic metabolites were selected in A and B group.3 different lysophosphatidyl choline, sphingosine 1-phosphate, ethanol amine amides, sphingosine choline phosphate, thromboxane, 14-methyl hexadecanoic acid showed the same changing trend and were significant different between B group and AMI group.Conclusions Characteristic ions selected by metabolic profiling technology had significant distinguishing ability for AMI patients and health control.They may provide early diagnosis for AMI.
