Abstract:
Objective:To study anti-tumor effect of Dunhuang medical prescription Dabupi Decoction on gastric cancer-bearing mice and effect of Dabupi Decoction combined with oxaliplatin on inflammatory immunity of gastric cancer-bearing mice based on IL-17/NF-κB signaling pathway.Methods:Mouse model of MFC gastric cancer subcutaneously bearing tumor was established and ran-domly divided into model group,oxaliplatin group,high,medium and low doses of Dabupi Decoction combined with oxaliplatin groups[21.58,10.79,5.40 g/(kg·d)],with 10 mice in each group,male and female cage rearing.Administration began after 8 days of inoculation and continued for 14 days;next day after the last administration,eyeball blood was taken,mice were killed,tumor tissues were taken and weighed,and tumor inhibition rate was calculated.ELISA was used to detect contents of IL-17 and IL-6 in mice serum,immunohistochemistry(IHC),RT-qPCR and Western blot were used to detect IL-17,IL-6,NF-κB and p-NF-κB mRNA and protein expressions in mice tumor tissues,respectively.Results:Tumor inhibition rates of oxaliplatin group,high,medium and low doses of Dabupi decoction combined with oxaliplatin groups were 33.02%,52.92%,46.33%and 39.52%,respectively,and tumor quality of each treatment group was significantly lower than that of model group(P<0.01).High,medium and low doses of Dabupi Decoction combined with oxaliplatin groups were higher than that of oxaliplatin group.Compared with model group,contents of IL-17 and IL-6 in serum and expressions of IL-17,IL-6,NF-κB p65 and pNF-κB p65 mRNA and protein in tumor tissues in each treatment group were significantly reduced(P<0.01,P<0.05).Compared with oxaliplatin group,levels of IL-17 and IL-6 in serum and expres-sions of IL-17,IL-6,NF-κB p65 and pNF-κB p65 mRNA and protein in tumor tissues in high and medium doses of Dabupi Decoction combined with oxaliplatin groups were significantly reduced(P<0.01,P<0.05).Conclusion:Dunhuang medical prescription Dabupi Decoction has a certain anti-tumor effect on MFC gastric cancer-bearing mice,which can regulate inflammatory immunity and inhibit occurrence and development of gastric cancer by inhibiting IL-17/NF-κB signaling pathway.
