Abstract：Objective To investigate the effects of Pulsatilla saponin D and sorafenib on the metastasis of human hepa?toma cell line. Methods The human hepatoma cell line BEL-7402 cells were divided into Pulsatilla saponin D group (con?centration of 11.9 mg/L), sorafenib group (concentration of 2.15μmol/L), the combined group (Pulsatilla saponin D 11.9 mg/L+Sorafenib 2.15μmol/L) and the control group (ordinary broth). The inhibition effects of Pulsatilla saponin D and sorafenib monotherapy and combination therapy on BEL-7402 cell migration were detected by MTT assay, Transwell chamber experi?ment and cell scratch experiment. Western blot assay was used to detect the expression levels of matrix metalloproteinase (MMP)-2 and MMP-9 gene protein. Results MTT assay showed that Pulsatilla saponin D (11.9 mg/L), sorafenib (2.15μmol/L) monotherapy and combination therapy had inhibitory effects on BEL-7402 cell proliferation, and the 24-h inhibi?tion rate was<15%. Results of Transwell chamber experiment and cell scratch test showed that the migration inhibitory rate was significantly higher in combination group than that of monotherapy group (P<0.01). The combined effect of madicine was the addition (0.85≤Q≤1.15). Western blot detection showed that there was a higher effect of down-regulation on MMP-2 and MMP-9 in combined group than that of monotherapy group. Conclusion Pulsatilla saponin D and sorafenib synergis?tically inhibit the metastasis of BEL-7402 cells. The joint effects are superior to monotherapy.
