J Nanosci Nanotechnol:磷酸钙硅酸盐和硅酸钙水泥可有效抑制破骨细胞的活性

2018-06-30 MedSci MedSci原创

磷酸钙骨水泥(CPSC)可刺激成骨细胞增殖并促进成骨,但CPSC如何通过细胞因子调节抑制破骨细胞活性尚不清楚。在目前的研究中,我们通过将磷酸一钙(MCP)掺入硅酸钙水泥(CSC)中来合成CPSC,并分析了CSC和CPSC对破骨细胞存活与MTT的影响。我们发现CSC和CPSC培养基均可降低破骨细胞活性,流式细胞术进一步表明CSC和CPSC可抑制破骨细胞活性。为了阐明潜在的机制,评估了与破骨细胞活性相

磷酸钙骨水泥(CPSC)可刺激成骨细胞增殖并促进成骨,但CPSC通过细胞因子调节抑制破骨细胞活性的机制目前尚不清楚。本研究中,研究人员将磷酸一钙(MCP)掺入硅酸钙水泥(CSC)中来合成CPSC,并分析了CSC和CPSC对破骨细胞存活与MTT的影响。

结果发现,CSC和CPSC培养基均可降低破骨细胞活性。流式细胞术进一步表明,CSC和CPSC可抑制破骨细胞活性。为了阐明其背后潜在的机制,研究人员还评估了与破骨细胞活性相关的细胞因子相关的基因和蛋白质水平。结果表明,水泥处理的细胞中破骨细胞活性受到抑制。此过程由骨水泥刺激的细胞因子的分泌有关。

综上所述,该研究结果表明,CSC和CPSC通过抑制破骨细胞活性似乎是骨替代物的良好替代物,然而,其促进骨骼生长的确切机制还需要进一步研究。

BJJ:老年人半髋置换用骨水泥还是非骨水泥?

髋关节骨折是一种常见于老年患者的严重创伤,据估计,其发生率会在未来20年中持续增长。对于关节囊内的移位性股骨颈骨折常需要选择行半髋置换术,很多全国性的临床指南推荐骨水泥型半髋关节假体。而为了避免骨水泥带来的死亡率和并发症,有着严重合并症的病例往往对选择非骨水泥型假体。 过去的文献在这方面报道的结果一直存在争议。有少数患者甚至在术后短期就会发生死亡,但相关的研究往往又受到样本量的限制。来自

BJJ:治疗感染性骨不连的新方法

骨与关节感染是目前骨科医生需要面对的最为棘手的问题之一。这类病例的治疗本身非常复杂,且往往同时又伴有需要长期治疗的合并症。尤其是存在节段性骨缺损、复杂的感染病史、伤口或骨愈合不良的病例,治疗起来就显得更为困难。 虽然治疗骨或关节置换感染的外科治疗手段很多,但业内在最终的理想治疗方法上仍存在争议。植入抗生素骨水泥是其中一种已被证明了的治疗方法,它可以局部释放高浓度抗生素的同时减小全身副作用

J Spinal Disord Tech:经皮椎体成形术单侧疗效优于双侧

骨质疏松性椎体压缩性骨折(OVCFs)是导致腰痛和行动能力丧失的一个常见问题。置入许多固定器具的传统开放式手术因疏松的骨质固定性不好而经常失败。 经皮椎体成形术(VP)是一种安全有效的治疗手段。经典的VP通过双侧经椎弓根或椎弓根外将骨水泥注入。许多学者将VP的技术挑战视为重度椎体压缩性骨折的相对或绝对禁忌症。然而,最近有研究报道称单侧VP可以达到同样的疗效。理论上来讲,单侧VP可以减少手

JBJS:髋关节假体周围骨折发生率危险因素分析

曾有文献报道,非骨水泥较骨水泥关节置换术的假体寿命要小于骨水泥型假体,,随着非骨水泥全髋置换使用率和患者生存年限的增加,临床医生对其并发症的发生率认识也不断更新。有报道称术中股骨干骨折的发生率不断增长与的非骨水泥使用率的增加关系密切。有学者认为可以通过完善术前计划和提高手术技巧降低并发症,但是目前没有数据支持这一定论。 由于髋关节周围假体骨折的发生率并不高,所以需要通过大量的患者样本进行

了解了这些再去做髋关节翻修术

近年来,髋关节翻修手术明显上升,翻修技术也成为广大骨科医生关注的热点问题。翻修手术第一步是取出失败的假体。完美的假体取出技术应达到以下两方面的目标:对骨结构破坏最小的同时完全取出假体和骨水泥;尽可能保留骨量,防止医源性骨缺损。随着手术器械和手术技术的进步,假体取出也有很多的方法,每个医生选择的方法也不尽相同。 全髋假体取出的要点为假体——骨水泥或假体——骨界面的松解和骨水泥的取出。与全膝

J Laryngol Otol:在内窥镜镫骨足板造孔术中,骨水泥固定对听力结果改善的研究

最近,有研究人员进行了旨在比较2种不同的镫骨足板造孔技术在临床不同时间点对听力结果影响的研究。研究人员对内窥镜手术组(组1,n=37)和显微镜手术组(组2,n=57)进行了回归性的比较。在所有的患者中都运用了小的膜孔和聚四氟乙烯活塞技术。在假体和砧骨之间用骨水泥来进行固定,并且旨在内窥镜组中使用。比较参数中包括了骨传导阈值和气骨差异。研究发现,术前气骨差异在组2中为31.26dB,在组2中为32.
