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 ***: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 *** analysis was performed on the fasting venous blood obtained from each patient in both *** 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 ***:A total of 59 differential biomarkers between the experimental group and the control group were *** 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 ***: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 *** biomarker 3-oxo-4,6-choladienoic acid may have potential diagnostic value in patients with adenomatous polyp of the colon and yang-deficiency constitution.(Trial Registration ***02986308)
