Abstract
AIM: To investigate the effects of QHF formula in combination with low-dose cisplatin (DDP) on tumor angiogenesis and growth in H22 hepatocellular carcinoma in mice and observe their toxic reactions.
METHODS: Forty-eight BALB/c mice were inoculated with mouse hepatocellular carcinoma H22 cells in the right axillary skin to establish a mouse model of H22 hepatocellular carcinoma. The model mice were randomly divided into four groups: QHF group, DDP group, QHF plus DDP group and normal saline (NS) group. The inhibitory effects of these drugs on tumor growth were evaluated by calculating the reduced rate of tumor growth. The toxicity of these drugs was examined by observing the general condition of mice and the spleen index. The morphological changes of tumor cells were observed under an optical microscope. The microvessel density (MVD) in tumor tissue was evaluated by immunohistochemistry.
RESULTS: The tumor weight was significantly lower in the QHF group, DDP group, and QHF plus DDP group than in the NS group (0.63 g ± 0.16 g, 0.45 g ± 0.23 g and 0.33 g ± 0.15 g vs 1.22 g ± 0.22 g, respectively; all P < 0.01), while the tumor weight was significantly higher in the QHF group than in the QHF plus DDP group (P < 0.01). The reduced rates of tumor growth in the QHF group, DDP group and QHF plus DDP group were 47.45%, 63.11% and 72.95%, respectively. The MVD in tumor tissue was significantly lower in the QHF group, DDP group, and QHF plus DDP group than in the NS group (11.00 ± 1.56, 10.33 ± 1.49 and 6.87 ± 0.97 vs 19.93 ± 1.02, respectively; all P < 0.01). Compared with the QHF group and DDP group, the MVD was significantly lower in the QHF plus DDP group (both P < 0.01). Furthermore, a lower incidence of toxic reactions and a better quality of survival were observed in the QHF plus DDP group than in the DDP group.
CONCLUSION: Both of QHF and small-dose DDP have anti-angiogenic effects in H22 hepatocellular carcinoma in mice. QHF in combination with small-dose DDP has synergistic anti-angiogenic effects and can improve the quality of survival and reduce the incidence of toxic reactions in mice bearing H22 hepatocellular carcinoma.
