摘要
背景:肠道菌群及其代谢物能参与骨质疏松的病理进程,在骨质疏松的诊断与治疗中发挥重要作用。此外,运动可调控肠道菌群进而影响骨质疏松的发生发展。目的:总结肠道菌群对成骨细胞、破骨细胞和骨髓间充质干细胞等的作用与机制,探讨运动介导肠道菌群在调控骨质疏松中的潜在作用。方法:以“Intestinal flora,intestinal bacteria,metabolites of intestinal flora,bone metabolism,osteoporosis,exercise”和“肠道菌群,肠道细菌,肠道菌群代谢物,骨代谢,骨质疏松和运动”为关键词,检索PubMed和CNKI数据库1990-2023年间相关文献。结果与结论:①肠道菌群丰度和多样性变化以及氧化三甲胺和胆汁酸等肠道菌群代谢物水平变化,能作为骨质疏松诊断的生物标记物。②肠道菌群失调可导致肠屏障功能障碍和产生过量脂多糖、氧化三甲胺,诱导分泌肿瘤坏死因子α等炎症细胞因子、激活核因子κB信号通路以及加剧氧化应激等,进而促进破骨细胞分化、诱导成骨细胞凋亡以及影响骨髓间充质干细胞的成骨迁移;重塑肠道菌群稳态能抑制炎症反应、下调氧化应激,进而抑制破骨细胞分化、促进成骨细胞分化以及调控骨髓间充质干细胞的成骨迁移,防治骨质疏松。③运动能调控肠道菌群稳态、改善肠屏障功能、促进短链脂肪酸和胆汁酸分泌、下调血清脂多糖水平、降低氧化应激,进而抑制骨细胞凋亡、抑制破骨细胞分化、促进成骨细胞分化和调节骨细胞营养代谢,从而发挥防治骨质疏松的潜力。
BACKGROUND:Intestinal flora and its metabolites can participate in the pathological process of osteoporosis and play an important role in the diagnosis and treatment of osteoporosis.In addition,exercise can regulate the intestinal flora and thus affect the occurrence and development of osteoporosis.OBJECTIVE:To summarize the effects and mechanism of intestinal flora on osteoblasts,osteoclasts,and bone marrow mesenchymal stem cells,and the potential role of exercise-mediated intestinal flora in regulating osteoporosis.METHODS:“Intestinal flora,intestinal bacteria,metabolites of intestinal flora,bone metabolism,osteoporosis,exercise”were selected as keywords.Literatures from 1990 to 2023 were retrieved from PubMed and CNKI databases.RESULTS AND CONCLUSION:Changes in the abundance and diversity of intestinal flora and changes in the levels of intestinal flora metabolites such as trimethylamine oxide and bile acid can be used as biomarkers for the diagnosis of osteoporosis.The imbalance of intestinal flora can lead to intestinal barrier dysfunction and excessive production of lipopolysaccharides and trimethylamine oxide,induce the secretion of tumor necrosis factor-αand other inflammatory cytokines,activate the nuclear factorκB signaling pathway and aggravate oxidative stress,thus promoting osteoclast differentiation,inducing osteoblast apoptosis and affecting bone marrow mesenchymal cell migration.Remodeling intestinal flora homeostasis can inhibit inflammatory response,downregulate oxidative stress,inhibit osteoclast differentiation,promote osteoblast differentiation,and regulate the osteogenic migration of bone marrow mesenchymal cells to prevent and treat osteoporosis.Exercise can regulate intestinal flora homeostasis,improve intestinal barrier function,promote the secretion of short-chain fatty acids and bile acids,down-regulate serum lipopolysaccharide level,reduce oxidative stress,and then inhibit osteocyte apoptosis,inhibit osteoclast differentiation,promote osteoblast differentiation,and regulate osteocyte nutrient metabolism to exert the potential of preventing and treating osteoporosis.
