目的:分析丹参(SMB)注射液对宫颈癌细胞的促增殖效应及其相关调控分子表达的影响。方法将人宫颈癌Hela 细胞分别与终浓度为1.56 g/L、3.13 g/L、6.25 g/L、12.50 g/L、25.00 g/L、50.00 g/L、100.00 g/L、200.00 g/L 的 SMB 共同孵育,噻唑蓝(MTT)法检测细胞生长增殖的 A492值,流式细胞计数(FCM)分析细胞周期各时相细胞百分率及凋亡指数(AI)、增殖指数(PI);免疫细胞化学染色显示 PCNA、Bcl-2、Bax 分子表达水平,计算表达阳性细胞百分率,并以图像分析系统定量分析阳性表达强度。结果12.50~200.00 g/L 的 SMB 作用后,Hela 细胞的生长增殖呈递进性显著增高(均 P <0.05),且与 SMB 浓度间呈显著正相关(P <0.01);Hela 细胞 G0/G1期比例显著降低,S、G2/M期比例及 PI 值显著升高(均 P <0.05),AI 值变化无显著差异(P >0.05)。同时,Hela 细胞中 PCNA、Bcl-2的阳性表达率及表达强度明显增高,Bax 的阳性表达率及表达强度明显降低,其变化均与 SMB 作用浓度呈显著相关关系。结论 SMB 注射液可影响 Hela 细胞增殖凋亡调控分子的表达,发挥促增殖效应,在疾病治疗应用中须慎重。
