ABSTRACT
Rhizoma Dioscoreae Makino (RDM) is effective in treating gouty arthritis (GA) and hyperuricacidemia, especially in promoting uric acid excretion and reducing the inflammatory reaction. Bioactive constituents in RDM are mainly steroidal saponins such as dioscin, trillin, protodioscin and protogracillin. However, the mechanism of its anti-GA action is still unclear, owing to the complex pathological and physiological characteristics of GA, and integration of RDM with multiple components, multiple targets and multiple pathways. Herein, a GA rat model was induced with monosodium urate (MSU), and RDM reduced inflammation of rat synovium tissue. Through metabolomics analysis, 35 potential biomarkers with significant changes involved in the pathogenesis of GA induced by MSU were identified, and perturbations were restored after RDM treatment. The most correlated pathways involved in d-galactose, d-mannose, d-glucose, myoinositol, Phosphatidylcholine (PC) (160/160), LysoPC (150), phosphatidic acid (PA) [181(9Z)/181(11Z)] and glutathione induced by MSU were galactose metabolism, inositol phosphate metabolism, glycerophospholipid metabolism and glutathione metabolism, and the derivations of all those biomarkers could be regulated by RDM treatment. RDM has a therapeutic effect on GA by intervening in changes in endogenous metabolisms and the related metabolic pathways.
