Objective:To study the differences between the serum metabolites in patients with adenomatous polyps of the colon and yang-deficiency constitution and those without colon polyps and with balanced constitution,and look for biomarkers that can be used to distinguish between the two groups.Methods:General patient information was gathered,and Chinese medicine constitutions were collected in 940 patients who underwent electronic colonoscopy.A total of 119 patients with adenomatous polyps of the colon and yang-deficiency constitution were included in the experimental group,and 150 patients without colon polyps and with balanced constitution were included in the control group.Metabolomics analysis was performed on the fasting venous blood obtained from each patient in both groups.Principal component analysis and orthogonal partial least squares discriminant analysis were performed on the detection results,potential biomarkers were screened,metabolic pathway changes were determined,and the metabolic processes involved were discussed.Results:A total of 59 differential biomarkers between the experimental group and the control group were identified.The differential metabolites were found mainly in the glycerophospholipid metabolism pathway,and the bile acid 3-oxo-4,6-choladienoic acid was the biomarker that distinguished the experimental group from the control group.Conclusions:With the help of metabolomics analysis,the differential metabolites in patients with adenomatous polyps of the colon and yang-deficiency constitution and those in patients without colon polyps and with balanced constitution could be identified.The biomarker 3-oxo-4,6-choladienoic acid may have potential diagnostic value in patients with adenomatous polyp of the colon and yang-deficiency constitution.
