摘　　要：目的研究红景天苷对体外培养的人胃癌细胞SGC-7901增殖及生长的影响,并探讨其抗肿瘤作用的可能机制。方法实验分为对照组、0.50 mg/m L红景天苷组、1.00 mg/m L红景天苷组及2.00 mg/m L红景天苷组。通过MTT比色法、核仁组成区嗜银蛋白(Ag NOR)染色、流式细胞技术、细胞划痕实验的方法检测不同浓度红景天苷对SGC-7901细胞增殖、AgNOR表达、细胞周期、细胞凋亡及细胞迁移作用的影响。结果与对照组相比,不同浓度的红景天苷组SGC-7901细胞增殖及Ag NOR表达均受到明显抑制(P<0.05),结果呈明显的浓度-时间-效应依赖关系;细胞停滞在S期的比例减少、G_2/M期的比例增加(P<0.05);细胞凋亡率升高,迁移率降低(P<0.05)。结论红景天苷能抑制SGC-7901细胞增殖,并能阻滞细胞周期和诱导细胞凋亡,降低胃癌细胞的迁移能力。Objective To investigate the effect of salidroside on the proliferation and growth of in vitro cultured human gastric carcinoma SGC-7901 cells,and to explore the possible anti-tumor mechanism. Methods Cells were divided into control group,0. 50 mg / m L salidroside group,1. 00 mg / m L salidroside group and 2. 00 mg / m L salidroside group. Cell proliferation was assessed by MTT array. Argyrophilic nucleolar organiser region proteins（ Ag NOR） staining was used to determine the expression of Ag NOR in nuclear. The cell cycle and apoptosis were detected by flowcytometry test. Migration rate was measured by cell scratch assay. Results Compared with control group,the proliferation and Ag NOR expression of SGC-7901 cells were inhibited significantly in salidroside groups（ P〈0. 05） with a concentration-,time- and effect-depent manner; cell circle arrest increased at G2/ Mphase,but decreased at S phase（ P〈0. 05）; the rate of cell apoptosis increased,while cell migration rate was down-regulated（ P〈0. 05）. Conclusion Salidroside can effectively inhibit proliferation,arrest cell cycle,induce apoptosis and decrease migration rate of SGC-7901 cell.
