椎间盘退变中胶原蛋白的代谢失衡

Collagen metabolism imbalance in intervertebral disc degeneration

背景:腰椎间盘退行性疾病是导致腰痛和下肢神经症状的常见疾病。胶原代谢的平衡在维持椎间盘的稳定中发挥着重要的作用。目的:对椎间盘退变中胶原蛋白代谢失衡的研究进展作一综述。方法:由第一作者在中国知网、PubMed、Web of Science数据库中检索2024年5月之前发表的相关文章,中文检索词为“椎间盘退变疾病”“胶原代谢”“胶原酶家族”“胶原合成相关因子”“细胞因子”,英文检索词为“degenerative disc disease”“Collagen metabolism”“Collagenase family”“Collagen synthesis related factors”“Collagen breakdown related factors”。最终纳入76篇文献进行综述。结果与结论:在椎间盘退变的过程中,胶原蛋白代谢的平衡在维持正常椎间盘的稳定中起到至关重要的作用。当椎间盘发生退变时,椎间盘内分泌大量促炎因子、胶原酶,并发生氧化应激反应等,使椎间盘内胶原蛋白分解增加,同时抑制生长因子、胶原蛋白合成酶、胶原蛋合成相关因子的生成,使椎间盘内胶原蛋白合成减少。上述两种情况共同作用使椎间盘内胶原蛋白的代谢平衡被打破,进一步加剧了椎间盘退变的进程。

BACKGROUND:Lumbar disc degeneration is a common disease that causes lower back pain and lower limb neurological symptoms.The balance of collagen metabolism plays an important role in maintaining the stability of the intervertebral discs.OBJECTIVE:To review the research progress in the imbalance of collagen metabolism in intervertebral disc degeneration.METHODS:The first author searched for relevant literature published before May 2024 in CNKI,PubMed and Web of Science databases.Search terms were“degenerative disc disease,”“collagen metabolism,”“collagenase family,”“collagen synthesis related factors,”and“collagen breakdown related factors”in Chinese and English.Seventy-six articles were finally included for review.RESULTS AND CONCLUSION:In the process of intervertebral disc degeneration,the balance of collagen metabolism plays a crucial role in maintaining the stability of the normal intervertebral disc.When intervertebral disc degeneration occurs,a large amount of pro-inflammatory factors,collagenase,and oxidative stress reactions occur in the intervertebral disc,which increases the breakdown of collagen in the intervertebral disc.At the same time,it inhibits the generation of growth factors,collagen synthase,and collagen synthesis-related factors,resulting in a decrease in collagen synthesis in the intervertebral disc.The combined effect of the above two conditions disrupts the balance of collagen metabolism in the intervertebral disc,further exacerbating the process of intervertebral disc degeneration.
