Abstract:
Objective To observe the effect of Xinjia-Liangfu(XJLF)formula on human gastric cancer(SGC-7901)tumor growth in nude mice and its impact on survivinand Caspase-3 expression in tumor tissue. Methods The animal model of SGC-7901 xenografted nude mice was established, and all the mice were randomly divided into 6 groups, namely model control group, 5-Fu group, XJLF formula high-dose group, XJLF formula medium-dose group , XJLF formula low-dose group and drug combination group(XJLFformula medium-dose and 5-Fu). After 10 days of continuous treatment, tumor inhibition rate was calculated and the expression of Survivin and Caspase-3 was detected by immunohistochemistry techniques. Results The tumor inhibition rates of 5-Fu group, XJLF formula high-dose group, XJLF formula medium-dose group, XJLF formula low-dose group and drug combination group were 55.03%, 56.38%, 41.23%, 23.09%and 60.28%respectively, and the tumor inhibition rate of drug combination group was significantly increased compared to the model control group(P<0.05), 5-Fu group(P<0.05)and XJLF high-dose group(P<0.05) Meanwhile, the Caspase-3 expression was significantly up-regulated and the Survivin expression was significantly down-regulated in drug combination group(Caspase-3 was 77 539.74±50 912.5, Suvivin was 35 709.1±10404.4)compared to the model control group(Caspase-3 was 18 464.71±7 537.01,Suvivin was 63 449.4±50 498.8), P<0.05 or 0.01, 5-Fu groupCaspase-3 was (47 198.89±10 751.2), Suvivin was(37 016.8±6 024.4), P<0.05 or 0.01and XJLF formula high-dose groupCaspase-3was (44213.57±7041.6), Suvivin was (38811.1±7313.0)respectively. Conclusion The tumor inhibition rate of drug combination group was higher than XJLF formula high-dose group and 5-Fu group. Also combination group hadstronger effect compared to model control group in terms of down-regulation of Caspase-3 expression and up-regulation of Survivin expression, which indicates a benefit ofXJLF and 5-Fu combination treatment.
