Core Tip

Core tip: Functional dyspepsia (FD) is a common gastrointestinal disorder in clinic. Gastric hypersensitivity (GHS) and anxiety are important factors triggering or aggravating it, however, the mechanisms by which affect the development of FD are still unknown. In part, this is due to a lack of suitable animal models of FD with anxiety and GHS. Our study provided such a newly developed rat model induced by sequential stress. It demonstrated the complex behavioral characteristics of anxiety and GHS, and the complicated alterations in some anxiety-related neurobiochemical modulators such as 5-hydroxytryptamine, γ-aminobutyric acid, brain-derived neurotrophic factor and nesfatin-1 in the hippocampus, plasma and gastric fundus.
