Abstract: 目的观察黄芪在高糖环境下对人脐静脉内皮细胞(HUVECs)Apelin/APJ mRNA表达的影响,探寻黄芪对HUVECs的作用机制。方法原代培养HUVECs,根据实验要求分为:对照组、高糖组、低浓度黄芪组(0.1g/L浓度黄芪+高糖)、高浓度黄芪组(0.2g/L浓度黄芪+高糖),用不同浓度的葡萄糖和黄芪注射液培养24h后,用细胞增殖活力实验(CCK-8)检测HUVECs的增殖活力;在倒置相差显微镜下观察HUVECs的形态变化;逆转录聚合酶链反应(RT-PCR)检测Apelin/APJmRNA的表达。结果经过24h培养,与对照组相比,高糖组细胞增殖活力明显降低(P<0.05),镜下可见细胞形态改变,Apelin/APJ mRNA的表达减少(P<0.05)。与高糖组相比,黄芪干预组细胞增殖活力升高(P<0.05),镜下可见细胞形态明显改善,Apelin/APJ mRNA的表达增高(P<0.05)。结论黄芪可减轻高糖对内皮细胞的损伤,亦可通过升高Apelin/APJ对HUVECs起保护作用。
