Multi-Omics Study of COPD Stages and Traditional Chinese Medicine Syndromes

This is a multicenter, prospective, observational cohort study of patients with chronic obstructive pulmonary disease (COPD), individuals with pre-COPD, and healthy participants. The study will enroll approximately 400 participants, including individuals with pre-COPD, patients with stable COPD at different GOLD stages, patients with acute exacerbation of COPD, and healthy controls. Participants will not be assigned to any study intervention. Clinical information, pulmonary function, imaging information, traditional Chinese medicine syndrome assessment, and biological samples will be collected according to the study protocol. Multi-omics analyses, including metagenomics, metabolomics, transcriptomics, and proteomics, will be used to characterize molecular features associated with COPD stages and traditional Chinese medicine syndromes. Participants will be followed to evaluate clinical characteristics, exacerbations, pulmonary function changes, and multi-omics features over time.

Electronic Six-Image Pulse Diagnosis for TCM Syndrome Identification in Sleep Disorders

This is a prospective, single-center, observational diagnostic accuracy study designed to evaluate whether three-dimensional electronic pulse diagnosis can support traditional Chinese medicine syndrome identification in patients with sleep disorders. Participants underwent standardized symptom assessment, expert traditional Chinese medicine syndrome differentiation, and bilateral cun, guan, and chi pulse signal acquisition using the KY-M-A1 electronic pulse diagnostic system. Six-position pulse parameters were used to construct a Six-Image pulse vector, which was compared with a symptom-based Six-Image vector. The main purpose of the study is to assess the concordance between electronic pulse-derived features and expert-determined traditional Chinese medicine syndromes.
