Abstract:
Objective To study the effects of supplemental Dangguibeimukushen pill prescription on the expressions of MMP13 and bFGF in tumor tissues on H22 hepatoma bearing mice.Methods H22 hepatoma bearing mice was employed to carry out anti-tumor experiment in vivo in this study.A total of 60 mice were randomly divided into model group,DDP positive control group,low and high dosage of supplemental Dangguibeimukushen pill treatment group,supplemental Dangguibeimukushen pill combined with DDP group.In each gruop,gastric infusion was performed continuously 14 d.The tumor growth and the general conditions of mice were recorded.After the last administration of gavages orally treatment,all mice were anaesthetized and killed by cervical disloca-tion method to obtain completely tumor tissue for further HE staining measure and detection of MMP13 and bFGF in tumor tissue with the method of RT-qPCR and immunohistochemistry.Results The tumor volume of model group and low dosage of supple-mental Dangguibeimukushen pill treatment group were larger than that of other groups,futhermore,ulceration were found inside tumor,and basic integrity were observed of tumor capsule.However,in all the treatment groups,the tumor volume was relatively smaller,and the capsule of tumor was incomplete,ulceration of different degrees and bleeding when tumor was peeled off.In combi-nation groups,the tumor volume was much smaller,and the tumor had incomplete capsule and less ulceration inside.Pathological observation showed that connective tissue was found inside tumor,cells were sparsely spread and the number of necrosis cancer cells were increased in all treatment groups.RT-qPCR detection showed that the mRNA expression of MMP13 and bFGF in each treat-ment group were decreased comparing with the model group,and the difference was statistically significant(P <0.05).Immunohis-tochemical detection showed that the expression of MMP13 and bFGF in the combined group were less colored and weakly positive expression comparing with the positive group or the pure Chinese medicine treatment group,the difference was statistically signifi-cant(P <0.05).Conclusion Dangguibeimukushen pill could downregulate the expression of MMP13 and bFGF of tumor tissue in H22 hepatocarcinoma xenograft mice at mRNA and protein levels,and played a vital role in inhibiting cancer invasion and angiogen-esis,reducing toxics and side effects and enchancing its efficiency.
