摘　　要：采用基于UHPLC-Q-Exactive Orbitrap/MS的脂质组学方法,分析脂多糖(lipopolysaccharide, LPS)诱导的急性肺损伤(acute lung injury, ALI)模型小鼠的肺组织磷脂代谢的变化,观察桔梗汤对异常脂质的调节,探究桔梗汤对LPS诱导的ALI的调节作用。分别采集空白对照组、ALI模型组、地塞米松(阳性药)组、桔梗汤组小鼠的肺组织样本,实验方案经南京中医药大学实验动物伦理委员会批准实施,提取其脂质成分,采用UHPLC-Q-ExactiveOrbitrap/MS脂质组学技术研究各组肺组织磷脂的变化。LPS诱导的ALI小鼠磷脂出现代谢异常,具体表现为磷脂酰胆碱(PC)类脂质出现明显的上调,磷脂酰乙醇胺(PE)、磷脂酰甘油(PG)、磷脂酰丝氨酸(PS)、磷脂酰肌醇(PI)等脂质出现代谢紊乱,桔梗汤对这些变化磷脂具有一定的回调作用。LPS诱导的ALI引起体内磷脂紊乱,桔梗汤对代谢紊乱的磷脂具有调控作用。Using the lipidomics method based on UHPLC-Q-Exactive Orbitrap/MS,the change of phospholipid metabolism in lung tissue of mice induced by lipopolysaccharide(LPS)-induced acute lung injury was analyzed to observe the regulation of abnormal lipids by Jiegeng Decoction and to explore the regulation effect of Jiegeng Decoction on LPS-induced acute lung injury.The lung tissue samples from control group,model group,dexametha-sone(positive drug)group,and Jiegeng Decoction group were collected and the lipid components of the sample were extracted.All procedures over mice were performed in accordance with the Guidelines for Care and Use of Laboratory Animals of Nanjing University of Chinese Medicine,and the experiments were approved by the Animal Ethics Committee of our university.The lipidomics technique of UHPLC-Q-Exactive Orbitrap/MS was used to study change of phospholipids in lung tissue of each group.LPS induced acute lung injury in mice with metabolic abnormalities of phospholipids,the specific performance of the PC was significantly upregulated,phosphatidyl ethanolamine(PE),phosphatidyl glycerol(PG),phosphatidyl serine(PS),phosphatidylinositol(PI)and other metabolic disorders,Jiegeng Decoction have a certain role in these phospholipids.LPS-induced acute lung injury caused disturbances of phospholipid in vivo,and Jiegeng Decoction regulates metabolic phospholipids.
