Abstract
AIM: To detect the gastric expression of Toll-like receptor 2 (TLR2), TLR4, nuclear factor-kappa B 65 (NF-κB65), and serum levels of interleukin-6 (IL-6) and IL-8 in mice with Helicobacter pylori (H. pylori) associated gastritis with splenogastric hygropyrexia syndrome (SGHS), and to investigate the mechanism underlying the therapeutic effect of Mieyou decoction in the treatment of chronic gastritis.
METHODS: BALB/c mouse were randomly divided into five groups: a control group, a model group, a high-concentration Mieyou decoction group, a low-concentrations Mieyou decoction group, and a triple therapy group (tinidazole, clarithromycin and bismuth potassium citrate granules), with 14 rats in each group. The BALB/c model of H. pylori-associated gastritis with SGHS using a composite method (fatness food + hygropyrexia environment + H. pylori). After the success of modeling, continuous administration 14 d. Immunohistochemistry was used to detect the expression TLR2, TLR4 and NF-κB65 proteins in gastric tissue; qPCR was used to detect the expression of TLR2, TLR4 and NF-κB65 mRNAs; ELISA was used to detect the levels of IL-6 and IL-8 in serum.
RESULTS: Compared with the control group, the expression of TLR2, TLR4, NF-κB65 proteins and mRNAs, and serum levels of IL-6 and IL-8 in the model group were significantly increased. After therapy, the expression of TLR2, TLR4, NF-κB65 proteins and mRNAs, and serum levels of IL-6 and IL-8 in the high-concentration Mieyou decoction group, low-concentration Mieyou decoction group, and triple therapy group were significantly decreased compared with the model group. The expression of TLR2, TLR4, NF-κB65 proteins and mRNAs, and serum levels of IL-6 and IL-8 in the high-concentration Mieyou decoction group were higher than those in the triple therapy group, but the differences were not statistically significant.
CONCLUSION: Mieyou decoction has a role in the treatment of H. pylori-associated gastritis with SGHS possibly by intervening the TLRs/NF-κB65 signal pathway.
