Mechanisms of traditional Chinese medicine monomers in the treatment of osteoarthritis by targeting autophagy / 中国组织工程研究

ABSTRACT

BACKGROUND:Increasing studies have shown that autophagy plays an important role in the treatment of osteoarthritis,and moderate autophagy can preserve the normal physiological function of osteoarticular chondrocytes.Traditional Chinese medicine(TCM)monomers can target and modulate autophagy to treat osteoarthritis,and their characteristics such as single components,clear efficacy,low price,and easy availability have obvious benefits in the treatment of osteoarthritis.OBJECTIVE:To review the effects of TCM monomers on the targeted regulation of autophagy in the treatment of osteoarthritis and the research progress,with a view to laying a foundation for the treatment of osteoarthritis and even other bone metabolic diseases.METHODS:Relevant literature published from January 2012 to October 2022 was retrieved in PubMed,Web of Science,CNKI,and WanFang using the keywords of"traditional Chinese medicine,Chinese herbal monomer,autophagy,osteoarthritis"in English and Chinese.Inclusion and exclusion criteria were developed,and 63 relevant articles were finally included by screening through reading the title,abstract,and full-text content.RESULTS AND CONCLUSION:TCM monomers can treat osteoarthritis by targeting autophagy to inhibit chondrocyte apoptosis,protect cartilage extracellular matrix,reduce inflammation and antagonize oxidative stress injury.Different TCM monomers can regulate autophagy in the same way,and the same TCM monomers can affect autophagy in different ways.The combination of multiple monomers and the multi-target and multi-pathway regulation of autophagy by TCM monomers remain to be explored.The regulation of autophagy by TCM monomers can provide new ideas and strategies for the prevention and treatment of osteoarthritis.Moderate regulation of autophagy by TCM monomers to keep the autophagic flux unimpeded may be the key to treating osteoarthritis.
