目的 验证细胞衰老在糖皮质激素性骨质疏松中的作用,探究金天格胶囊治疗糖皮质激素性骨质疏松的机制。 方法 复苏人脐静脉内皮细胞(HUVEC)和小鼠胚胎前成骨细胞(MC3T3),诱导生成破骨细胞,将上述细胞均分为对照组(CN组)、模型组(MPS组)和金天格处理组(MPS+JTG组),使用稀释后的生理盐水溶解甲基强的松龙和金天格胶囊,待细胞贴壁后分别使用相应的药物处理对应组别的细胞。通过蛋白印迹、SA-β-Gal染色、DCFH-DA法染色、划痕实验和RT-PCR检测HUVEC细胞的衰老通路、修复能力;通过免疫荧光染色、ALP染色、Alizarin Red S染色和RT-PCR检测MC3T3细胞成骨能力;通过TRAP染色检测破骨细胞分化程度。将30只3周龄SPF级雌性SD大鼠随机分为对照组(CN组)、模型组(MPS组)和金天格处理组(MPS+ JTG组),10只/组。建立糖皮质激素性骨质疏松模型并连续灌胃给药3个月。人道主义处死大鼠后取股骨及静脉血,进行micro-CT扫描、检测大鼠股骨骨体积分数变化情况,并检测大鼠血清骨代谢指标。 结果 网络药理学结果显示,虎骨有效成分与糖皮质激素性骨质疏松存在大量交集靶点,并与P53等细胞衰老相关靶点具有较强的结合力。在细胞水平,与模型组相比,在金天格处理后的HUVEC细胞模型中,P53、P21等衰老蛋白表达被抑制(P<0.01)、氧化应激减弱(P<0.01),而细胞迁移、成血管能力增强(P<0.05)。同样,金天格处理组的MC3T3细胞成骨和矿化能力也明显增强(P<0.001),并且抑制了破骨细胞的分化。在动物水平,经过14 d MPS腹腔注射的大鼠股骨骨量较对照组明显丢失,而金天格胶囊可以缓解骨量的丢失及血清骨代谢指标紊乱(P<0.05)。 结论 金天格胶囊可以通过抑制HUVEC细胞的衰老、增强MC3T3细胞的成骨能力并抑制破骨,促进骨髓内相关血管的迁移和生成,改善成骨能力和骨骼血供并促进成骨、抑制破骨,从而缓解糖皮质激素性骨质疏松。
