摘　　要：目的基于血清脂质组学研究非酒精性脂肪性肝病(NAFLD)患者的脂质代谢特征。方法将2020年1月至2021年1月上海市普陀区中心医院30例NAFLD患者和30名正常人群纳入研究。采用UPLC-Q-Orbitrap/MS对两组人群血清进行脂质组学分析,使用主成分分析法和正交偏最小二乘法判别分析对数据进行多维统计分析,以VIP值>1、P<0.05的代谢物为差异性脂质生物标志物。结果两组体重指数,碱性磷酸酶、总蛋白、胆碱酯酶、尿素、甘油三酯比较,差异有统计学意义(P<0.05)。两组年龄、性别、总胆红素、直接胆红素、白蛋白、γ-谷酰胺转肽酶、丙氨酸转氨酶、天冬氨酸转氨酶、总胆汁酸、肌酐、尿酸、肾小球滤过率、高密度脂蛋白胆固醇、低密度脂蛋白胆固醇、总胆固醇比较,差异无统计学意义(P>0.05)。共筛选出181个差异性脂质生物标志物,包括甘油三酯、甘油二酯、鞘磷脂、磷脂酰丝氨酸、磷脂酰胆碱、磷脂酰肌醇、磷脂酰甘油、磷脂酰乙醇胺、O-酰基-ω-羟基脂肪酸、单硬脂酸甘油酯、溶血磷脂酰肌醇、溶血磷脂酰甘油、溶血磷脂乙醇胺、溶血磷脂酰胆碱及神经酰胺等。结论NAFLD患者的脂质代谢与正常人群有显著差异,本研究筛选出的181个脂质生物标志物可作为潜在的NAFLD的新靶标。Objective To study the characteristics of lipid metabolism in patients with non-alcoholic fatty liver disease(NAFLD)based on serum lipidomics.Methods A total of 30 NAFLD patients and 30 normal people in Putuo District Central Hospital of Shanghai from January 2020 to January 2021 were included in the study.UPLC-Q-Orbitrap/MS was used for lipidomics analysis of serum of two groups.Principal component analysis and orthogonal partial least squares discriminant analysis were used for multidimensional statistical analysis of data,metabolites with VIP value>1and P<0.05 were used as differential lipid biomarkers.Results There were statistically significant differences in body mass index,alkaline phosphatase,total protein,cholinesterase,urea,and triglyceride between two groups(P<0.05).There were no significant differences in age,gender,total bilirubin,direct bilirubin,albumin,γ-glutamic transpeptidase,alanine aminotransferase,aspartate aminotransferase,total bile acid,creatinine,uric acid,glomerular filtration rate,high density lipoprotein cholesterol,low density lipoprotein cholesterol,and total cholesterol between two groups(P>0.05).A total of 181 differential lipid biomarkers were screened,including triglyceride,diglyceride,sphingomyelin,phosphatidylserine,phosphatidylcholines,phosphatidylinositols,phosphatidylglycerides,phosphatidylethanolamines,O-acyl-ω-hydroxy fat ty acid,monoglyceride,lysophosphatidylinositol,lysophosphatidylglyceride,lysophosphatidylethanolamine,lysoph-osphatidylcholine,and ceramide.Conclusion Lipid metabolism in NAFLD patients is significantly different from that in the normal population,181 lipid biomarkers screened in this study can be used as potential new targets for NAFLD.
