Abstract: Objective: To observe the effect of Compound Sophora Flavescens Injection on the radiosensitivity of the human nasopharyngeal carcinoma CNE-2 cells,and to explore its mechanism. Methods: The human nasopharyngeal carcinoma CNE-2 cells were cultured in vitro. The inhibitory rates of proliferation of CNE-2 cells after treated with different concentrations of Compound Sophora Flavescens Injection for 24, 48, and 72 h were detected by MTT method. The semi-inhibitory concentration (IC50) of Compound Sophora Flavescens Injection on CNE-2 cells was calculated. The CNE-2 cells were divided into control group(without irradiation and adminnistration), irradiation group (treated with 2 and 4 Gy X-ray irradiation) and combination group(treated with different concentrations of Compound Sophora Flavescens Injection and then received X-ray irradiation). MTT assay was used to detect the inhibitory rates of proliferation of the CNE-2 cells in various groups, flow cytometry was used to detect the apoptotic rates of the CNE-2 cells in various groups,and clone formation test was used to detect the survival rates of the CNE-2 cells in various groups. Results: After treated with different concentrations of Compound Kushen Injection for 24, 48 and 72 h, the inhibitory rates of proliferation of the CNE-2 cells were increased compared with the CNE-2 cells without Compound Kushen Injection treatment (P<0.05) in an dose-dependent manner;the inhibitory rate of proliferation of the CNE-2 cells after treated with Compound Kushen injection for 48 h was higher than 24 h (P<0.05).The apoptotic rate of the CNE-2 cells in radiation group was higher than that in control group (P<0.05); the apoptotic rate of the CNE-2 cells in combination group was higher than that in radiation group (P<0.05);the survival rate of the CNE-2 cells in combination group was lower than that in radiation group(P<0.05). Conclusion: Compound Sophora Flavescens Injection can promote the irradiation-induced apoptosis of nasopharyngeal carcinoma CNE-2 cells, therefore, Compound Sophora Flavescens Injection has the radiosensitization effect on the CNE-2 cells.
