Objective:The preventive and therapeutic effects of direct moxibustion on a gastric cancer rat model induced by the intragastric administration of N-methyl-N’-nitro-N-nitrosoguanidine(MNNG)were *** in the co-stimulatory molecules CD80 and CD86 on antigen-presenting cells in gastric tissues as well as related cytokines in serum were *** aim of the study was to explore the immunological mechanisms by which direct moxibustion may prevent gastric cancer lesions,thereby providing a basis for studies on the immunological mechanisms by which moxibustion prevents tumor ***:Sixty healthy male Wistar rats were randomly divided into four groups:Control,control+moxibustion,model,and moxibustion groups.A gastric cancer rat model was induced by intragastric administration of 20 mg/mL MNNG,with a dose of 1 mL/100 g body weight,once daily for 16 *** control+moxibustion and moxibustion groups received direct moxibustion simultaneously with modeling,continuing for 16 *** the experiment,gastric tissue was collected,and morphological changes in the gastric mucosa in each group of rats were observed through H&E ***(IHC)and a western blotting were used to detect the expression levels of CD80 and CD86 in gastric ***-linked immunosorbent assays(ELISA)were used to measure the levels of interleukin-12(IL-12),interferon-gamma(IFN-γ),and tumor necrosis factor-beta(TNF-β)in rat ***:Upon macroscopic observation,the gastric mucosa of rats in the control and control+moxibustion groups appeared uniformly red,with a glossy mucosal surface,normal gastric wall elasticity,and clear,regular mucosal folds,without hyperplasia or bleeding *** the model group,the gastric mucosa was reduced in volume,the gastric wall thinned,elasticity decreased,mucosal folds were disordered,and yellow-white cauliflower-like lesions and yellow-brown hyperkeratosis were *** the moxibustion group,the gastric mucos
