Abstract:

Objective To screen metabolic markers in the blood of patients with insomnia disorder, and to analyze the abnormal metabolic pathways. Methods Totally, 30 patients with insomnia disorder(insomnia disorder group) and 30 healthy subjects(healthy control group) from January to December 2021 at Jiading District Central Hospital of Shanghai University of Medicine and Health Sciences were enrolled. The general data were collected. Ultra performance liquid chromatography tandem mass spectrometry(UPLC-MS/MS) was used to determine plasma metabolites. Based on VIP value, fold change(FC) and P value, significantly differential metabolites were screened between insomnia disorder group and healthy control group. Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment pathway analysis was performed on differential metabolites. Results Totally, 1 656 metabolites were determined, and 181 differential metabolites between insomnia disorder group and healthy control group were selected. Among them, 115 metabolites were screened for positive ion mode(61 cases of up-regulation and 54 cases of down-regulation), and the top 10 metabolites with VIP values were ethylenediaminetetraacetic acid, carnitine, N-(1-amino-3, 3-dimethyl-1-oxobutan-2-yl)-1-pentyl-1h-indole-3-formamide, [1-(cyclohexylmethyl)-1h-indole-3-carbonyl]-l-valine methyl ester, di tetracaine, glycerophosphate choline, hypoxanthine, palmitoyl serotonin, deferoxamine d2 and linolenic carnitine. The 66 metabolites(38 cases of up-regulation and 28 cases of down-regulation) were screened for negative ion mode, and the top 10 metabolites with VIP values were citrate, taurine, rhamnocitrin, uric acid, pyruvate, allantoin, 3', 5'-cyclic inosine monophosphate, D-lactic acid, (+) - 6-aminopenicillanic acid and oleic acid. The enrichment analysis of KEGG pathway showed that the differential metabolites were involved in the central carbon metabolism of cancer, ATP-binding cassette transporter and protein digestion and absorption. Conclusions Screening out representative metabolites and metabolic pathways in patients with insomnia disorder can provide potential targets for the diagnosis and treatment of insomnia disorder.
