The proliferative inhibition effect of matrine, cisplatin and the combination on the UBC cells. Drug concentration-cell viability curves were drawn as the viable cell percentage based on the cell viability assay (a, c, e, g). The synergistic effects between matrine and cisplatin were exhibited as Fa-CI plots (b, d, f, h). Data are from three repeated experiments with quadruplicate wells (mean ± SD). *P < 0.05, **P < 0.01, or ***P < 0.001 versus the control group
