Among them, 12 metabolites (dimethylarginine, N6\u2010acetyllysine, N\u2010acetylhistidine, N,N,N\u2010trimethyl\u2010alanylproline betaine, cysteine, 7\u2010methylguanine, N6\u2010carbamoylthreonyladenosine, pseudouridine, 5\u2010methylthioadenosine, N2,N2\u2010dimethylguanosine, aconitate and C\u2010glycosyl tryptophan) were identified as the specific biomarkers. The content of 12 metabolites were significantly higher in the DSPN group compared with the other two groups. Additionally, they showed good performance to discriminate the DSPN state. Correlation analyses showed that the levels of 12 metabolites might be more closely related to the glucose metabolic changes, followed by the levels of lipid metabolism.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The finding of the 12 signature metabolites might provide a novel perspective for the pathogenesis of DSPN.
