Abstract:
Intervertebral disc degeneration (IVDD) is a major cause of low back pain, and several studies have evaluated the efficacy of extracellular vesicles (EVs) in the treatment of IVDD. The databases PubMed, Embase, and Cochrane Library were systematically searched from inception to the end of 2022 to identify studies investigating the therapeutic potential of cell-derived EVs for IVDD treatment. The following outcome measures were utilized: magnetic resonance imaging (MRI) Pfirrmann grading system, disc height index (DHI), histological grading, and apoptosis rate. A comprehensive meta-analysis was conducted, including a total of 13 articles comprising 19 studies involving 218 experimental animals. Comparative analysis between normal cell-derived EVs and placebo revealed significant reductions in MRI grade, increased DHI values, decreased nucleus pulposus cell apoptosis rates, and improved tissue grades. These findings collectively demonstrate the effective inhibition of IVDD through the application of EVs derived from cells. In conclusion, this study provides an updated synthesis of evidence supporting the efficacy of EVs as a promising therapeutic approach for IVDD treatment.
摘要:
背景:椎间盘退变是下腰痛的主要原因,一些研究已经评估了细胞外囊泡在治疗椎间盘退变中的功效。
方法:数据库Pubmed,Embase,和Cochrane库从开始到2022年底进行了系统搜索,以确定研究细胞衍生的细胞外囊泡在椎间盘退变(IDD)治疗中的治疗潜力的研究。使用了以下结果测量:MRIPfirrmann分级系统,光盘高度指数(DHI),组织学分级,和凋亡率。
结果:进行了全面的荟萃分析,包括总共13篇文章,包括涉及218只实验动物的19项研究。正常细胞来源的细胞外囊泡和安慰剂之间的比较分析显示,MRI等级显着降低,DHI值增加,降低髓核细胞凋亡率,和改善组织等级。
结论:这些发现共同证明了通过应用源自细胞的细胞外囊泡有效抑制椎间盘退变。总之,这项研究提供了最新的证据合成支持细胞外囊泡作为IVDD治疗的一种有前景的治疗方法的有效性.
