Abstract: Objective The aim of this study was to analyze serum lipidomics of patients with non-alcoholic simple fatty liver (NAFL) and non-alcoholic steatohepatitis (NASH). Methods 107 patients with NAFL and 92 patients with NASH were enrolled in our hospital between May 2015 and May 2020. The basic data were collected, and serum lipidomics were analyzed by ultra-high performance liquid chromatography-tandem mass spectrometry. Results Compared with in NAFL group, the levels of 3 kinds of free fatty acids (FFA, 12:0, 18:1 and 20:0), 2 kinds of diacylglycerols (DAG, 36:3 and 36:4), 16 kinds of triacylglycerols (TAG, 52:4, 52: 5, 54: 4, 54: 5, 54: 8, 56: 5, 56: 7, 56: 8, 56: 9, 58: 4, 58: 8, 58: 9, 58: 10, 58 : 11, 60: 6 and 60: 12), 2 kinds of phosphatidylcholines (PC, 36:5 and 38:6), 1 phosphatidylserine (PS, 33:0), 2 kinds of lysophosphatidyl ethanolamines (LPE, 36:2 and 39:1), 2 kinds of cholesterol esters (CE, 20:4 and 22:6, 4 kinds of sphingomyelins (SM, 36:3, 38:2, 40:1 and 42:1) and 3 kinds of ceramides (Cer, 40:1, 41:1 and 42:1) increased in NASH group, while 3 kinds of FFA (16: 1, 22: 4 and 22: 5), 1 TAG (54: 2), 3 types of PC (32:1, 35:4 and 38:3), 5 types of phosphatidylinositols (PI, 32:1, 34:1, 34:2, 36:4 and 40:4), 5 kinds of phosphatidalcholines (PlsCho, 34:2, 36:2, 36:4, 40:5 and 42:5) and 7 kinds of phosphatidal ethanolamines (PlsEtn, 36:6, 38:5, 38:6, 38:7, 40:7, 40:8 and 42:7) levels decreased (P<0.05). Conclusion There is a significant difference in serum lipid metabolism between patients with NAFL and patients with NASH, which might be help clarify the pathogenesis of patients with non-alcoholic simple fatty liver diseases.
