英文摘要Rheumatoid arthritis (RA) is a systematic autoimmune disease that causes pain, swelling, stiffness and loss of function in joints. With the rapid development of systems biology, ‘-omics’ techniques have play significant roles in the study occurrence and development of rheumatoid arthritis. Metabonomics, focusing on studying the low molecular weight metabolites in biological samples, measures the dynamic metabolic responses to pathophysiological stimuli or genetic modifications through detection and quantification of all metabolites. However, no single analytical technique can detect all of the metabolites unprejudicedly, therefore combining different platforms in order to obtain as much underlying information as possible is common in metabonomic study. In the current work, we used LC/MS and GC/MS to investigate the plasma metabolic fingerprints of RA patients compared with healthy controls, and to realize the metabolic alterations of RA. The partial least squares-discriminant analysis (PLS-DA) model showed evident separation between RA patients and healthy counterparts. The metabolic state of RA patients resulted in the increased plasma levels of carnitine, palmitoylcarnitine, saturated and mono-unsaturated phosphatidylcholine, proline, alanine, 3-hydroxybutyrate, glycerate, myoinositol, glucose, cholesterol, urea and free fatty acids, as well as decreased levels of glycochenodeoxycholic acid, lyso-phosphatidylcholine, polyunsaturated phosphatidylcholine and phosphatidylethanolamine, threonine and branched-chain amino acids. The mainly changed metabolic pathways involved in RA patients were lipid metabolism, pentose phosphate metabolism, amino acids metabolism and inositol phosphate metabolism.
