Core Tip

Core Tip: An important feature of functional gastrointestinal disorders (FGIDs) is accompanied with emotional disorders, such as anxiety and depression. Clinically, acupuncture not only improves physical symptoms, but also has a unique psychological effect in treatment of FGIDs. However, the underlying mechanisms remain unclear. Brain-gut crosstalk may mediatepathological process of FGIDs, corticotropin releasing factor (CRF) is an important mediator in brain-gut crosstalk. So, our study focused on the CRF of brain-gut, we hypothesized that electroacupuncture improved mood disorders and visceral pain in irritable bowel syndrome, which may be achieved through paraventricular nucleus CRF-colonic CRF-receptor 1 and downstream pathway.
