目的:
2
研究痰瘀互结型冠心病患者的血浆脂质组学特征,寻找其与健康志愿者之间的差异脂质代谢物。
方法:
2
采集痰瘀互结型冠心病患者及同年龄段健康志愿者血浆,采用UPLC-Q/TOF-MS进行血浆脂质组学研究。血浆样本在正、负离子模式下分别进行检测,同时采集一级和二级质谱(

z
检测范围分别为100~2 000,50~2 000),采用正交偏最小二乘法-判别分析(OPLS-DA)建立脂质组学模型,基于多元统计发现并鉴定差异脂质代谢物。
结果:
2
OPLS-DA模型可明显区分痰瘀互结型冠心病患者及健康志愿者,发现并鉴定了15个差异脂质代谢物,分别为C16 sphinganine,植物鞘氨醇,

痰瘀互结型冠心病患者及健康志愿者的血浆脂质组学特征存在显著差异,血浆差异脂质代谢物有助于痰瘀互结型冠心病的的准确辨证。
Objective:
2
To study on the plasma lipidomics characteristics of coronary heart disease (CHD) patients with syndrome of of intermingling of phlegm and static blood
and to find differential lipid metabolites between them and healthy volunteers.
Method:
2
The plasma samples from CHD patients with syndrome of intermingling of phlegm and static blood and healthy volunteers of the same age were collected. The plasma lipidomics was carried out by UPLC-Q/TOF-MS. The plasma samples were detected under positive and negative ion modes
and the primary and secondary mass spectrometry datas were collected simultaneously
and the
m
/
z
ranges were 100-2 000 and 50-2 000
respectively. The lipidomics model was established by orthogonal partial least squares discriminant analysis (OPLS-DA). Differential lipid metabolites were identified based on multivariate statistics.
Result:
2
OPLS-DA model could obviously distinguish CHD patients with syndrome of intermingling of phlegm and static blood and healthy volunteers. A total of 15 plasma differential lipid metabolites were identified
such as C16 sphinganine

Conclusion:
2
There are significant differences in plasma lipid characteristics between CHD patients with syndrome of intermingling of phlegm and static blood and healthy volunteers. The plasma differential lipid metabolites are helpful for the accurate differentiation of CHD patients with syndrome of intermingling of phlegm and static blood.
