Qing-Kai-Ling Injection Acts Better Than Shen-Fu Injection in Enhancing the Antitumor Effect of Gefitinib in Resistant Non-Small Cell Lung Cancer Models

Figure 3

QKL injection increased, and SF injection antagonized the proapoptotic effect of gefitinib in PC-9-PIK3CA-M and H1975 cells: (a) apoptosis assay to assess the combination effect of gefitinib and QKL/SF for 48 h in PC-9-PIK3CA-M cells. (b) Apoptosis assay to assess the combination effect of gefitinib and QKL/SF for 48 h in H1975 cells. (c) The statistics of apoptotic rate induced by gefitinib and QKL in PC-9-PIK3CA-M and H1975 cells. (d) The statistics of apoptotic rate induced by gefitinib and SF in PC-9-PIK3CA-M and H1975 cells. Data are presented as the mean ± standard deviation of three independent experiments. vs. control group, vs. gefitinib group, and vs. QKL/SF group. QKL, Qing-kai-ling injection; SF, Shen-fu injection.
