ABSTRACT
Objective:
To discuss the effect of Yiqi Jianpi Huayu recipe (YQJPHY) combined with 5-fluorouracil(5-FU) on the growth and immune function of subcutaneous transplanted tumor in MFC tumor bearing 615 mice.Method:
Twenty-four mice were inoculated subcutaneously to establish the transplanted tumor model of gastric cancer in mice, and then randomly divided into model control group, YQJPHY (20 g·kg-1)group, 5-FU (25 mg·kg-1) group and (YQJPHY+5-FU) combined group, with 6 rats in each group. After the last administration, the transplanted tumor, spleen and thymus were stripped completely. The tumor inhibition rate, thymus and spleen index were calculated. Flow cytometry was used to determine the content of myeloid-derived suppressor cells (MDSCs) and its subtype polykaryotype cells (PMN-MDSC), single karyotype cells (M-MDSC) in both peripheral blood and tumor tissue, and macrophages and their M1 type, M2 type, T lymphocyte, B lymphocyte, and natural killer cells (NK cells) in peripheral blood. Expressions of arginase-1(Arg-1) and inducible nitric oxide synthesis (iNOS) gene in tumor tissues were detected by Real-time PCR.Result:
Compared with model control group, the weight of mice in YQJPHY group increased, whereas the weight of tumor, the weight of tumor, the index of thymus and spleen decreased in 5-FU group(PPPPPPPP+,CD4+,CD8+ T cell group decreased(PPPPPPConclusion:
YQJPHY can better inhibit the growth of subcutaneous transplanted tumor when combined with 5-FU, and improve immune status after chemotherapy. The mechanism may be related to the decrease of MDSCs content and the increase of T cell and macrophages content.
