摘要 目的探讨不同浓度阿司匹林对成骨细胞增殖的影响,为阿司匹林治疗骨质疏松提供理论依据。方法体外传代培养成骨细胞。成骨细胞传至第3~6代,接种于96或6孔板,随机分为阿司匹林低、中、高浓度组及对照组,阿司匹林低、中、高浓度组分别加入含阿司匹林0.5、2、10 mmol/L的培养液,对照组不予处理。采用分光光度计检测450 nm波长处的光密度值(OD值),代表成骨细胞的增殖活性;采用流式细胞仪检测成骨细胞凋亡率。结果阿司匹林低、中、高浓度组OD值分别为0.740±0.040、0.780±0.034、0.480±0.058,对照组为0.620±0.031。阿司匹林低、中浓度组细胞增殖活性明显高于对照组、阿司匹林高浓度组(P均<0.05),阿司匹林高浓度组明显低于对照组(P<0.05),而阿司匹林低、中浓度组比较无统计学差异(P>0.05)。对照组成骨细胞凋亡率为10.35%±0.39%阿司匹林低、中、高浓度组分别为8.30%±0.35%、9.96%±0.34%、11.30%±0.35%。阿司匹林低、高浓度组与对照组比较差异均有统计学意义(P均<0.01),阿司匹林中浓度组与对照组比较无统计学差异(P>0.05)。结论低浓度阿司匹林能促进成骨细胞增殖、抑制其凋亡,有可能用于骨质疏松的预防及治疗。
