目的研究黄连素抗小鼠巨噬细胞凋亡的作用,初步确定其抗凋亡的浓度,探讨其治疗动脉粥样硬化(athemsclemsis,As)的机制.方法以0.5 μmol/L的毒胡萝卜素(Tg)和50 μg/ml的墨角藻聚糖(Fuc)诱导RAW264.7巨噬细胞凋亡为实验模型,通过细胞毒性试验(MTT)法检测细胞存活率,Annexin V-FITC/P1流式细胞术检测细胞凋亡率.结果浓度为800 μg/ml的黄连素组与正常对照组细胞存活率相比差异有统计学意义(P<0.01);随着黄连素浓度的下降,细胞凋亡率旱现下降的趋势,黄连素(0.02～0.63 μg/ml)能有效抑制Tg和Fuc诱导的小鼠巨噬细胞凋亡.结论黄连素对RAW267.4细胞的增殖影响不大.黄连素能有效抑制Tg和Fuc诱导的小鼠巨噬细胞凋亡.

Objective To investigate the effect of berberine anti macrophages apoptosis, initially to determine the concentration of anti-apoptosis and to explore its mechanisms of treatment in atherosclerosis (AS). Methods Apoptosis of RAW264.7 macrophages is induced by 0.5 μmol/L Tg and 50 μg/ml Fuc. The cell survival rate and apoptosis rate was detected by MIT and flow cytometry, respectively. Results There was statistical significance between the berberine group of 800 μg/ml and normal group in the cell sur-vival rate(P<0.01). With the decline in concentration of berberine, the cell apoptosis rate showed a down-ward trend, berberine (0.02-0.63 μg/ml) effectively inhibited the cell apoptosis induced by Tg and Fuc. Conclusion Berberine group has little impact on the cell proliferation. Berberine can effectively inhibit the cell apoptosis induced by Tg and Fuc.
