Abstract: Objective To investigate the effects of extract from couple medicinals of strengthening healthy qi and eliminating pathogenic qi, i.e. Huangqi(Radix Astragali, astragalus root) and Ezhu (Rhizoma Curcumae, curcumae rhizome), and oxaliplatin(L-OHP)on inhibiting metastasis of CT26 wild-type(CT26.WT)cells, and regulating CXCR3, CCR6 mRNA, and protein expression in rats with colon cancer. Methods Orthotopic transplantation model of BALB/c colon carcinoma was built in mice. L-OHP or L-OHP combined with extract from huangqi and ezhu were given to the mice model. Effects of those medicines on liver metastasis were observed. CXCR3 and CCR6 mRNA expression were measured by using RT-PCR, and CXCR3, CCR6 protein expression was detected with Western Blot. Results L-OHP group and L-OHP combined with Chinese medicinal groups exhibited inhibitive effects on orthotropic tumor growth, and best effect was observed in positive expression (P<0.01). L-OHP combined with TCM can decrease the incidence of liver metastasis (P<0.05). Compared with the control group, mRNA expressions of CXCR3 and CCR6 decreased in the model group and low-dose group (P<0.01). Effects of L-OHP combined with low-dose Chinese medicine were more effective than other groups(P<0.01). Compared with the control group, CXCR3 and CCR6 protein expressions decreased sinificantly in all groups(P<0.05 or P<0.01). Conclusion Mechanism of huangqi, ezhu and oxaliplatin(L-OHP) to inhibit tumor metastasis may relate to downregulation of CXCR3, CCR6 mRNA and protein expression.
