The apoptosis of PC12 cells was not affected by the TQSS and EPSI formula. a The representative apoptotic pictures of PC12 cells detected by flow cytometry. The normal group and control group represent the cells cultured with 15 % serum DMEM and 1.5 % serum DMEM, respectively. The TQSS and EPSI groups stand for the apoptosis rates of PC12 cells treated with 1000 mg/L TQSS and 500 mg/L EPSI in 1.5 % serum DMEM, respectively. b The statistical analysis for control group and normal group. c The statistical analysis of the TQSS and EPSI treated group and the control group. Data are expressed as mean ± SD, n = 3, ***p < 0.001 versus normal
