ABSTRACT
Objective To study the effect of Xiaoyan Decoction on metastasis of non-small cell lung cancer by experimental study. Methods Through the scratch test, the effect of Xiaoyan Decoction on the migration ability of lung adenocarcinoma A549 cells was observed. The transwell migration assay was used to test the role of Xiaoyan Decoction in lung cancer stem cells migration. Results In the scratch test, the migration distance of lung adenocarcinoma A549 cells in 24, 48, and 72 h was significantly shorter than that of the control group at the time of the scratch test (P < 0.05). In the invasive experiment, the number of lung cancer stem cells passing through the transwell unit in Xiaoyan Decoction group was significantly less than that of the control group (P < 0.05). Conclusion Xiaoyan Decoction can effectively inhibit the invasion ability of lung cancer stem cells, and then affect their metastatic ability.
