Abstract Objective To conduct a study of type 2 diabetes mellitus (T2DM) patients and healthy people by metabolomics techniques, to explore the pathogenesis of T2DM. Methods Gas chromatography-mass spectrometry (GC-MS) combined with multiple multivariate statistical analysis methods was used to analyze plasma samples from healthy group (60 people) and the T2DM group (100 cases) in the Department of Nephrology, Jiamusi Central Hospital of Heilongjiang Province from June to July 2018. Results The method of plasma metabonomic analysis of T2DM based on GC-MS was established. Ten different metabolites such as L-alanine, lactic acid and L-valine in plasma were determined. Conclusion Based on metabolomic GC-MS analysis showed that the metabolic pattern of T2DM patients is significantly different from that of healthy group, which is related to metabolic pathways such as glucose and amino acid metabolism.
