- Abstract: OBJECTIVE:To discuss the effect and mechanism of supplementing qi and nourishing yin(SQNY) decoction on intestinal microbiome of mice with Lewis lung carcinoma after treated with cisplatin. METHODS: The model of C57BL/6 mice with lung carcinoma xenograft was established by subcutaneous seeding of Lewis cells and randomly divided into 4 groups (n=16), including saline group (NC group), cisplatin group (DDP group), CAP group (CAP group) and SQNY decoction combined with cisplatin group (DDP+SQNY group). The tumor sizes, weights and intestinal microbiota were detected. The serum levels of IL-6, IL-10, and TNF-α were detected by ELISA. The dendritic cell (DC) and macrophage subtype in spleen of mice models were detected by flow cytometry. RESULTS: ①The mean tumor sizes of mice in DDP group, CAP group, DDP+SQNY groups were all smaller than NC group (P<0.05). And the mean tumor size and weight in DDP+SQNY group were less than the other three groups (P<0.05). The mean animal weights in NC or DDP+SQNY group were higher than those in DDP group and CAP group (P<0.05). ②The mean levels of serum IL-6, IL-10 and TNF-α in DDP+SQNY group were less than those in the other three groups (P<0.05). ③The mean microbiota richness in DDP+SQNY group were less than those in the other three groups (P<0.05). The proportion of fecal microbiota was significantly changed in DDP+SQNY group, including upregulation of Firmicutes phylum and Bifidobacterium Genus, and downregulation of Bacteroidetes phylum(P<0.05). The amount of DC and M1/M2 macrophage subtype in spleen of DDP+SQNY group mice models were more than those in the other three groups (P<0.05). CONCLUSION: It′s suggested that SQNY decoction effectively enhances the anticancer effect of cisplatin by increasing the immune function and changing the intestinal microbiota.
