Effects of Shugan Hewei Granule on Depressive Behavior and Protein Expression Related to Visceral Sensitivity in a Rat Model of Nonerosive Reflux Disease

OBJECTIVE: To explore the effect of Shugan Hewei Granule (SGHWG) and to provide the experimental basis for its clinical application. METHODS: 40 healthy male Wistar rats were divided into 5 groups, with 8 rats in each group, including control group, model group, normal saline (NS) group, SGHWG group...

Sumario:OBJECTIVE: To explore the effect of Shugan Hewei Granule (SGHWG) and to provide the experimental basis for its clinical application. METHODS: 40 healthy male Wistar rats were divided into 5 groups, with 8 rats in each group, including control group, model group, normal saline (NS) group, SGHWG group, and Rabeprazole group. The control group was not treated. The model group was treated with fructose intake and mental stress to be the model of NERD. The other groups were treated as the model group and then gavaged with the corresponding drugs. The pH value of lower third of esophagus, immobile time in tail suspension test, CRF protein expression in both hypothalamus and anterior cingulate cortex (ACC), and SP protein in esophageal mucosa in lower third of esophagus detected by immunofluorescence and NMDAR1 protein expression in spinal cord detected by immunohistochemistry of each group were compared. RESULTS: The pH values of both the SGHWG group and the Rabeprazole group were higher than that of the model group (P<0.01), but the Rabeprazole group increased more obviously. The immobile time of the SGHWG group was shorter than that of the model group (P<0.01) and the Rabeprazole group (P<0.05). The expression of the CRF in the hypothalamus and ACC, NMDAR1 in the spinal cord, and SP in the esophageal mucosa in lower third of esophagus of the SGHWG group decreased significantly, compared with the model group (P<0.01), and was obviously lower than that in the Rabeprazole group (P<0.05). CONCLUSIONS: This study provided an evidence that SGHW formula was inferior to Rabeprazole in acid inhibition, but it might reduce the expression of CRF protein of hypothalamus and ACC, lower the levels of NMDAR1 in spinal dorsal horn and SP in esophageal mucosa in lower third of esophagus, and regulate depressive behavior simultaneously, related to the improvement of visceral hypersensitivity in rat model of NERD.
