J Bone Joint Surg Am:核心减压与骨髓抽吸浓缩液似乎并不能改善股骨头坏死的结果

2022-06-25 MedSci原创 MedSci原创

核心减压(CD)与骨髓抽吸浓缩液(BMAC)是一种可能改善股骨头坏死(ONFH)的结果的技术。

核心减压(CD)与骨髓抽吸浓缩液(BMAC)是一种可能改善股骨头坏死(ONFH)结果的技术。近日,发表于J Bone Joint Surg Am的一项回顾性队列研究评估了CD与BMAC增强的放射学无进展生存率(PFS);并确定了以转换为全髋关节置换术(THA)为终点的存活率,确定预后因素,并描述BMAC的细胞质量。

研究纳入61颗股骨头(40名患者),记录了患者的人口统计学、合并症、BMI、吸烟状况、病因、ONFH的位置和程度。所获得的数据与之前一项随机对照试验的结果进行了比较,即单独使用CD与使用聚甲基丙烯酸酯水泥(PMMA)增强的CD进行比较。

结果,在2年和5年内,CD与BMAC的放射学PFS分别为78.3%和53.3%。与单独的CD相比,CD与BMAC组的进展风险较低(HR0.45,p = 0.03),但是在多变量分析中,这一差异不再具有统计学意义。在2年和5年内,CD与BMAC的转换为全髋关节置换术的自由存活率(CFS)分别为72.1%和54.6%,与对照组(单独CD、CD和PMMA)相比没有差异。疾病进展的预测因素是肥胖(BMI≥30)和疾病的严重程度,由受累百分比、坏死指数或改良坏死指数来量化。

综上所述,该研究结果表明,与单独使用CD或使用PMMA的CD相比,使用BMAC的CD在PFS或CFS方面没有发现差异。BMI≥30和ONFH的严重程度是预测无进展生存或转为THA的独立统计学意义的因素。需要设计精良的随机对照试验来进一步加以探究。

Cell Physiol Biochem:淫羊藿苷对糖皮质激素诱导的大鼠股骨头坏死具有保护作用

股骨头的糖皮质激素(GC)相关性骨坏死(ONFH)是类固醇使用过多之后的常见并发症。我们之前的研究表明淫羊藿苷(ICA)可能对类固醇相关性骨坏死患者的骨髓间充质干细胞(BMSCs)有益。在这项研究中,我们调查了与GC相关ONFH中ICA增强成骨和抗脂肪形成的潜在机制。 使用CCK-8测定评估体外细胞增殖。茜素红S和碱性磷酸酶(ALP)活性测定成骨分化,油红O染色和TG含量测定评估成脂分化。RT-q
