电磁辐射对软骨的生物学效应研究进展

作为半刚性的、无血管和神经的结缔组织，软骨具有承重、应力缓冲和辅助运动等多种生理功能。软骨固有的修复能力差，损伤不易逆转且治疗难度大。近年来，大量研究结果显示适宜的电磁辐射对软骨细胞形态的维持及其细胞因子的分泌、软骨细胞外基质的稳态以及骨关节炎的治疗等都具有积极的意义。笔者就电磁辐射对软骨的生物学效应及其可能的作用机制作一综述。

Research progress on the biological effects of electromagnetic radiation on cartilage

As one kind of semi-rigid, avascular and non-innervated connective tissue, cartilage has a variety of physiological functions such as load-bearing, stress-cushioning and movement-assisting. The intrinsic self-repair ability of cartilage is poor, and it is not easy for cartilage to reverse and is difficult to treat the injury. In recent years, many studies have shown that appropriate electromagnetic radiation has positive significance for the maintenance of chondrocytes morphology, the secretion of its related cytokines, the homeostasis of cartilage extracellular matrix, and the treatment of osteoarthritis. This paper reviews the biological effects of electromagnetic radiation on cartilage and its possible mechanism.
