ETHNOPHARMACOLOGICAL RELEVANCE: Tianwang Buxin Dan (TWBXD) is a classical Chinese formula traditionally prescribed to "nourish Yin, calm the mind and relieve bowel stagnation" in disorders characterized by heart-kidney disharmony, insomnia, anxiety, and constipation. However, the mechanistic basis associating its gut-regulating and emotion-modulating effects along the gut-brain axis remains unclear.
AIM OF THE STUDY: To investigate whether TWBXD ameliorates functional constipation comorbid with emotional disturbances by modulating mitogen-activated protein kinase/Extracellular Signal-Regulated Kinase/c-Jun N-terminal Kinase (MAPK/ERK/JNK) signaling, hypothalamic-pituitary-adrenal (HPA)-axis activity, and autophagy-related mitochondrial integrity in the colon and hippocampus.
MATERIALS AND METHODS: A diphenoxylate-induced rat model of functional constipation with anxiety/depression-like behavior was treated with low, medium, or high doses of TWBXD. Intestinal transit, fecal parameters, and distal colonic transit were also assessed. Emotional behaviors were evaluated using open-field and elevated plus-maze tests. Colonic and hippocampal histopathology and ultrastructure were examined using hematoxylin and eosin staining, Nissl staining, and transmission electron microscopy. Serum corticotropin-releasing factor (CRF), adrenocorticotropic hormone (ACTH), and corticosterone (CORT) levels were measured using enzyme-linked immunosorbent assay. MAPK/ERK/JNK-related proteins and brain-derived neurotrophic factor (BDNF) were analyzed by Western blotting. The major chemical constituents of TWBXD were characterized using ultra-high-performance liquid chromatography-tandem mass spectrometry(UHPLC-MS/MS).
RESULTS: TWBXD dose-dependently improved intestinal transit, fecal moisture, and body weight gain, and alleviated anxiety-/depression-like behaviors. TWBXD preserved colonic mucosal architecture and hippocampal neuronal integrity, mitigated mitochondrial swelling and excessive autophagic vacuole formation, downregulated colonic phosphorylated ERK (p-ERK), phosphorylated JNK, and phosphorylated p38, restored hippocampal BDNF expression while normalizing p-ERK levels, and reduced serum CRF, ACTH, and CORT levels.
CONCLUSION: TWBXD exerts multi-target therapeutic effects on functional constipation with emotional disturbances by suppressing MAPK/ERK/JNK overactivation, normalizing HPA-axis hyperactivity, and protecting mitochondrial structure and autophagy along the gut-brain axis, providing mechanistic support for its traditional use in gut-brain-related disorders.
