To investigate the influence of Fuzheng Xiaoji Capsule on the proliferation inhibition of human gastric cancer cell BGC-823 and its apoptosis.Methods:Effects of Fuzheng Xiaoji Capsule on proliferation of BGC-823 cells were investigated with MTT assay.Flow cytometry was used to detect the cell apoptosis while the effect of apoptosis related gene of Fuzheng Xiaoji capsule on BGC-823 cell was measured by real time-PCR and Western blotting.Results:MTT assay showed that the BGC-823 cells were inhibited by Fuzheng Xiaoji Capsule compared with control group，after treated on 24 h.The inhibition rate increases with the increase of dose，which is dose dependent.At the dose of 5 mg/mL，the inhibition rate reached 86.71%(P<0.05).Flow cytometry demonstrated that Fuzheng Xiaoji Capsule could induce the apoptosis of BGC-823 cells.The early apoptosis rate of BGC-823 cells increased with the dose of the drug.At the dose of 2.5 mg/mL and 5 mg/mL，respectively，the early apoptosis of BGC-823 cells reached 15.76% and 38.25% respectively.By the results of Western blotting and real time-PCR，the expression of caspase-3、caspase-9 was significantly lower as the dose increased.Also，it could reduce the activity of Bcl-2，Bcl-xl，Survivin and increase the activity of Bax.Conclusion:Fuzheng Xiaoji Capsule could inhibit the proliferation of BGC-823 cells and induce their apoptosis.The possible mechanism was through activation of caspase cascade reaction.
