| 目的 探究三七总皂苷对人乳腺癌MDA-MB-231细胞凋亡的影响。方法 三七总皂苷作用于人乳腺癌MDA-MB-231细胞作为处理组，同时设置空白对照组； MTT法检测细胞活性变化，光镜观察检测细胞形态学变化，凋亡试剂盒检测细胞凋亡情况，casepase 3试剂盒检测casepase 3的酶活性情况。结果 与空白对照组相比，0.5、1.0和2.0mg/ml三七总皂苷组人乳腺癌MDA-MB-231细胞活性逐渐降低（P<0.05），呈时间和浓度依赖性；光镜观察下1.0、2.0mg/ml三七总皂苷组产生了凋亡小体；荧光观察下1.0、2.0mg/ml三七总皂苷组出现了核固缩现象；与空白对照组相比，0.5、1.0和2.0mg/ml三七总皂苷组人乳腺癌MDA-MB-231细胞casepase3的酶活性明显增加，差异具有统计学意义（P<0.05）。结论 三七总皂苷可降低人乳腺癌MDA-MB-231细胞的活性，具有促凋亡作用。 |

| Objective To explore the extraction of Panax notoginseng saponins(PNS) from Panax notoginseng and the effect on human breast cancer cell line MDA-MB-231.Methods The total saponin of hepaescin was used as treatment group on human breast cancer cell MDA-MB-231.The blank control group was set up at the same time.MTT method was used to detect the changes of cell activity;the morphological changes of cells were detected by light microscope;apoptosis was detected by apoptosis kit;the expression of casepase-3 was detected by kit.Results Compared with the blank control group,the activity of MDA-MB-231 cells in 0.5,1.0,2.0mg/ml groups decreased gradually in a time and concentration dependent manner;apoptotic bodies were produced in 1.0 and 2.0mg/ml PNS groups;karyopyknosis was observed in 1.0 and 2.0mg/ml PNS groups;compared with the blank control group,the enzyme activity of MDA-MB-231 casepase-3 in 0.5,1.0 and 2.0mg/ml PNS groups was significantly increased,and the difference was statistically significant (P<0.05).Conclusion Panaxnotoginsengsaponins can reduce the activity of MDA-MB-231 cells and promote apoptosis. |
