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 2

QKL injection and TRQ injection, but not SF injection, increased the sensitivity of gefitinib in PC-9-PIK3CA-M and H1975 cells: (a) MTT assay on the cell viability after the treatment with QKL/SF and gefitinib for 48 h and 72 h in PC-9-PIK3CA-M cells. (b) MTT assay detecting the cell viability after the treatment with QKL/SF and gefitinib for 48 h and 72 h in H1975 cells. (c) MTT assay detecting the cell viability after the treatment with TRQ and gefitinib for 48 h in PC-9-PIK3CA-M and H1975 cells. Data are presented as the mean ± standard deviation of three independent experiments. vs. gefitinib alone, vs. QKL/SF alone. QKL, Qing-kai-ling injection; SF, Shen-fu injection; TRQ, Tan-re-Qing injection.
