Metabolomic analysis of tongue coating in colorectal cancer patients with damp⁃heat syndrome
To investigate the biological characteristics of tongue coating in colorectal cancer patients with damp-heat syndrome using metabolomics technology.
Methods
2
Tongue coating samples were collected from colorectal cancer patients with damp-heat syndrome, patients with non-damp-heat syndrome, and healthy controls. These groups were designated as the damp-heat syndrome group, non-damp-heat syndrome group, and healthy control group, respectively. Liquid chromatography-mass spectrometry (LC-MS) was used to detect the metabolites in each sample. After obtaining the metabolic fingerprinting, principal component analysis (PCA), partial least squares discriminant analysis (PLS-DA), and orthogonal partial least squares discriminant analysis (OPLS-DA) were performed to identify the related metabolites and explore the associated metabolic pathways.
Results
2
The differential metabolites in the tongue coating of colorectal cancer patients with damp-heat syndrome
were primarily composed of hormones, signaling mediators, nucleic acids, and peptides, etc. Key differential metabolites included acetylcholine, cytosine,
L
-tryptophan, and serotonin. The major differential metabolic pathways involved lipid metabolism, amino acid metabolism, nucleic acid metabolism, the digestive system, the nervous system, and sensory systems.
Conclusions
2
The tongue coating in colorectal cancer patients with damp-heat syndrome exhibits distinct metabolomic characteristics. The integration of traditional Chinese medicine (TCM) tongue diagnosis with modern analytical technologies is an important method for inheriting and promoting the distinctive features of TCM. These findings offer insights for further investigation into the pathogenesis and progression of colorectal cancer, thereby guiding treatment strategies.
