- Abstract: BACKGROUND:Resistance to the inflammatory response is an important part of promoting the repair of damaged tissue and improving the local inflammatory response caused by medical bio-implant materials has been a key issue to be addressed in recent years. OBJECTIVE:To summarize the anti-inflammatory effects of common metal ions and related molecular mechanisms to provide some theoretical references for improving the early inflammatory response of hosts caused by bio-implant materials. METHODS:A computer search of the relevant literature in PubMed,Web of Science,CNKI and WanFang databases was conducted using"metal ions,magnesium ion,zinc ion,silver ion,copper ion,inflammation,anti-inflammatory effects,oxidative stress,immunoregulation,signaling pathways"as Chinese and English search terms.Preliminary screening was conducted by reading the titles and abstracts.Finally,80 papers were included for result analysis and summary. RESULTS AND CONCLUSION:(1)Metal ions such as magnesium,zinc,silver and copper have a good anti-inflammatory effect.The strength of this anti-inflammatory effect is strongly correlated with the dose and duration of action.In the future,consideration can be given to controlling the release rate of ions and adjusting the appropriate therapeutic concentration to achieve the best anti-inflammatory effect.(2)Magnesium ions and zinc ions exhibit excellent anti-inflammatory activity,with magnesium ions often being beneficial in anti-inflammatory therapy in the form of compounds such as magnesium sulfate and zinc ions regulating the body's inflammatory response with zinc feed as the main source of zinc supplementation.(3)Silver and copper ions have some anti-inflammatory effects,but are still predominant for their excellent antibacterial activity,mainly in the form of nanoparticles and bio-coatings.(4)Magnesium and zinc metal ions can be combined with natural extracts to form complexes to exert anti-inflammatory effects,and this method has the advantage of being inexpensive and widely available and is a sustainable and green approach,which is worthy of clinical promotion.(5)Metal ions such as magnesium,zinc,silver and copper exert anti-inflammatory effects by reducing host oxidative stress damage,modulating immune cells and inhibiting inflammatory signaling pathways such as nuclear factor-κB,Toll-like receptor,STAT3 and NOD.(6)The molecular mechanism related to the anti-inflammation of metal ions is a complex network,which is not the effect of a single pathway,but should be a combination of multiple signaling pathways.There are still many potential mechanisms that have not yet been explored,and more systematic elucidation of the interconnections between various signaling pathways is needed in the future.
