(A) The effect of each drug individually and in combination on cell apoptosis in QGY7701, HL7702 and SMMC7721 cells with different concentrations and treatment durations were monitored under microscopy (100×). (B, C) The apoptosis of QGY7701, HL7702 and SMMC7721 cells induced by the drugs individually and in combination at different concentrations and treatment durations were detected using FITC Annexin V-PI Apoptosis detection kit (BD Pharmingen, USA) and measured by flow cytometry analysis (means ± S.D). Each experiment was repeated at least three times.
