Methods: Sixty C-IBS patients were assigned to 2 groups by simple randomized method, i.e. EA group (30 cases) and Mox group (30 cases). Both EA and Mox treatments were performed on bilateral Tianshu (ST 25) and Shangjuxu (ST 37) for 30 min each time, 6 times per week, for 4 consecutive weeks. The gastrointestinal symptoms and psychological symptoms of the two groups were scored before and after treatment. The effects on the corresponding functional brain areas, namely the anterior cingulate cortex (ACC), insular cortex (IC) and prefrontal cortex (PFC) were observed by functional magnetic resonance imaging (fMRI) before and after treatment. Results: Compared with the Mox group, greater improvements in abdominal distension, defecation frequency, difficulty in defecation and stool features were observed in the EA group (all P〈0.01), both Hamilton Anxiety Rating Scale and Hamilton Depression Rating Scale scores were significantly decreased in the EA group (all P〈0.01). Finally, decreased activated voxel values were observed in the ACC, right IC and PFC brain regions of EA group with 150 mL colorectal distension stimulation (P〈0.05 or P〈0.01). Conclusions: Both EA and Mox could significantly improve some of the most intrusive symptoms of C-IBS patients, and EA was more effective than Mox. The therapeutic effect of these two therapies might through modulating of the brain-gut axis function. (Registration No. ChiCTR- TRC-11001349).展开更多

Metabolomics is the scientific study of dynamic chemical processes involving metabolites as well as metabolic response of living organisms. Metabolomics, a research method with integrity and dynamics, corresponds to the overall regulatory effect of acupuncture and is in line with the overall concept of traditional Chinese medicine(TCM) and the concept of homeostasis. In the recent years, metabolomics has been extensively applied to the clinical and experimental study of IBD, and its potential applied value has been unanimously acknowledged by the researchers. In this article, the application status of metabolomics in acupuncture is summarized, and the research ideas to study the mechanism of acupuncture in the regulation and control of IBD by metabolomics are preliminarily explored.展开更多
