RÉSUMÉ
BACKGROUND:More and more studies have shown that oxidative stress should play an important role in the treatment of osteoporosis.Oxidative stress should cause the accumulation of oxidation activity,which will damage bone-related cells.Finally,it causes the imbalance of bone resorption and bone formation,resulting in a decrease in bone volume and the destruction of the slight structure.Research in recent years has found that some natural products can regulate oxidative stress to treat osteoporosis.The characteristics of extensive sources and small side effects have obvious advantages in the treatment of osteoporosis,and the efficacy is objective. OBJECTIVE:To discuss the mechanism of natural product regulation of oxidation stress in treatment of osteoporosis,conduct a review based on the latest related research progress,provide reference and ideas for more natural products to treat osteoporosis in the future,and provide data support for the clinical application of natural compounds in the treatment of osteoporosis. METHODS:"oxidative stress,free radical,antioxidant,phytotherapy,plant extracts,medicinal plants,herbal medicine,osteoporosis,bone density,bone loss"were used as the keywords in PubMed,Web of Science,Embase,Cochrane,VIP,CBM,WanFang,and CNKI databases to search relevant articles published from January 2010 to February 2023.Inclusion and exclusion criteria were developed,and 64 relevant articles were selected by reading titles,abstracts,and full texts. RESULTS AND CONCLUSION:(1)Some natural products have antioxidant effects and can regulate osteogenic differentiation,osteoblast bone matrix mineralization,osteoclast-mediated bone resorption,proliferation,differentiation,activity,and apoptosis of bone-related cells by improving oxidative stress,thus affecting bone metabolism.(2)These natural products with antioxidant effects play a role in treating osteoporosis by improving bone remodeling balance.(3)The research on the combination of a variety of natural products to improve osteoporosis remains to be explored.(4)The use of natural products to regulate oxidative stress may become a powerful weapon for the clinical treatment of osteoporosis in the future.
RÉSUMÉ
The repair of bone defect has always been a difficulty in the field of orthopedics. The development of stem cell transplantation-based regenerative medicine has brought hope to overcome this disease. Mesenchymal stem cells (MSCs) have strong osteogenic differentiation potentials, which are excellent seed cells for bone tissue engineering. Natural small molecule compounds are characterized by abundant sources, complex structures, and extensive and unique biological activities. In recent years, it has been found to be a natural inducer for the efficient induction of differentiation of mesenchymal stem cells into osteoblasts, and has important application prospects in the treatment of bone lesions by stem cells. In this paper, recent advances in the induction of osteogenic differentiation of mesenchymal stem cells by natural small molecules are reviewed. It is expected to accelerate the clinical application of mesenchymal stem cells in bone lesions and bone tissue engineering.
