Abstract:
This paper discussed the synergistic anti-tumor effect of Shuangdan Capsules combined with 5-fluorouracil(5-FU) on human liver cancer cell line Huh-7 and tumor bearing mice. The effects of Shuangdan Capsules combined with 5-FU on the activity and vascular endothelial growth factor(VEGF) receptor protein expression of Huh-7 cells were investigated, and the effects of drug combination on tube formation of HUVEC cell were also verified. In addition, the mice model of Huh-7 was established to observe the anti-tumor effect of drug combination and the distribution of tumor blood flow in tumor bearing mice by using molecular imaging. HPLC analysis showed that Shuangdan Capsules mainly consisted of danshensusodium, protocatechuic aldehyde, paeoniflorin, rosmarinic acid, alkannic acid, salvianolic acid B, and paeonol. In MTT experiment, the inhibition rate of Shuangdan Capsules(20 mg·L~(-1)) and 5-FU(1 μmol·L~(-1)) on Huh-7 cells was 60%, and the CI value was 0.59, suggesting that these two drugs had synergistic anti-hepatoma cells effect. The expression of VEGF receptor in Huh-7 cells was inhibited by the combination of these two drugs. In addition, the process of HUVEC was slow, and the number, length and area of the lumen branches decreased significantly. In vivo, Shuangdan Capsules combined with 5-FU inhibited the growth and prolongation of survival of Huh-7 cells in subcutaneous transplanted tumor nude mice; serum expression of CD31 and VEGF in nude mice were decreased, while caspase-3 was increased. Meanwhile, the drug combination significantly inhibited the expressions of MMP2 and VEGF in tumor tissues. Ultrasound showed that Shuangdan Capsules combined with 5-FU also inhibited tumor angiogenesis and reduced blood flow of tumor tissue. The results showed that Shuangdan Capsules combined with 5-FU may inhibit tumor angiogenesis by inhibiting VEGF and MMP2 expressions, thereby blocking tumor growth.
