Study on the Use of Traditional Chinese Medicine Diagnostic Tools to Assist in Identifying the Clinical Characteristics of Inflammatory Bowel Disease and Research on Metabolic Plastids of Tongue Coating

This study will be conducted at the outpatient clinic of China Medical University hospital. It is expected to enroll two groups of 30 subjects, including the experimental group must meet the clinical diagnosis of IBD, and the control group without IBD and have no obvious gastrointestinal symptoms . This proje ct uses modern TCM diagnostic tools, such as tongue diagnosis instrument, auscul tation instrument, TCM constitution questionnaire, and pulse diagnosis instrument to establish the comparison of physiological and biochemical indicators such as TCM phenotype and laboratory tests data in patients with IBD. Besides, another purpose of this project is to analyze the tongue coating metabolites of patients with IBD by mass spectrometry, and to establish a research model of tongue coating an d metabolomics for patien ts with IBD and the prognosis analysis of acute and remission phases.
