Effects of Huangqi Jianzhong Decoction on Inflammatory Factors and HGF/c-Met Signaling Pathway in Rats with Gastric Ulcer of Spleen-stomach Deficiency and Cold Syndrome
Objective:To observe the effects of Huangqi Jianzhong Decoction on inflammatory factors and HGF/c-Met signaling pathway in rats with gastric ulcer of spleen-stomach deficiency and cold syndrome.Methods:60 rats were randomly divided into 4 groups:normal group,model group,Huangqi Jianzhong Decoction group[Huangqi Jianzhong Decoction 6.8 g/(kg·d)]and omeprazole group[omeprazole enteric-coated capsules 4.2 mg/(kg·d)],with 15 rats in each group.Except for the normal group,the other groups were established with the spleen-stomach deficiency cold syndrome model by the method of qi depletion and qi destruction combined with the method of hunger and satiety disorder,and the rat gastric ulcer model was established with glacial acetic acid method.The body weight and ulcer index of rats in each group were compared.HE staining was used to observe the pathological changes of gastric tissue.The levels of IL-6,IL-1β and TNF-α in serum were detected by en-zyme-linked immunosorbent assay.The expression of hepatocyte growth factor(HGF)and hepatocyte growth factor receptor(c-Met)in gastric tissue was detected by immunohistochemistry.The mRNA levels of HGF and c-Met in gastric tissue were detected by real-time PCR.Results:Compared with the normal group,the body weight of the model group was decreased,the ulcer index was increased,the contents of IL-6,IL-1β,TNF-α were increased,HGF was increased,HGF and c-Met mRNA were increase d(P<0.05);compared with the model group,the body weight of the rats in Huangqi Jianzhong Decoction group and omeprazole group was increased,the ulcer index was decreased,IL-6,IL-1β and TNF-α were decreased,HGF,HGF and c-Met mRNA were increased(P<0.05).Con-clusion:Huangqi Jianzhong Decoction can promote the repair of gastric mucosa by inhibiting inflammatory factors and regulating the expression of HGF/c-Met pathway.
