摘要:


文题释义:

微弧氧化:又称等离子体电解质氧化、阳极火花沉积,是一种通过调节电解液成分和电参数,在电弧放电产生的瞬时高温高压作用下,于铝、镁、钛等阀金属及其合金表面形成致密陶瓷氧化膜的表面改性技术。
生物医用材料:是以医疗为目的,用于与组织接触以形成功能的无生命的材料,是用来对生物体进行诊断、治疗、修复或替换其病损组织、器官或增进其功能的一类高技术新材料。


背景:微弧氧化技术能够有效地将生物活性元素掺杂到金属表面,提高生物医用金属材料的抗菌性能和抗炎性能,因此该技术已成为生物医用材料的研究热点之一。

目的:重点介绍微弧氧化技术及其与其他表面改性技术联合应用制备植入物表面涂层的抗菌性能和抗炎性能。
方法:以“微弧氧化,抗炎性能,抗菌性能,金属植入物”为中文检索词检索中国知网和万方数据库,以“micro-arc oxidation、antibacterial properties,anti-inflammatory properties,metal implants”为英文检索词检索PubMed数据库,检索时间范围为1996年1月至2022年12月,根据纳入和排除标准初筛后,最后保留89篇文献进行归纳总结。

结果与结论:微弧氧化陶瓷层提高了钛、镁等合金的抗菌性能和抗炎性能,联合其他表面改性技术有效解决了孔隙对合金表面性能的影响,进一步提高了氧化膜的生物学性能,在骨科和牙科等领域有着广泛的应用前景。目前研究多局限于金属涂层,而且大部分研究集中在银、铜等具有良好抗菌性能的金属元素,仅有少数研究提到氧化石墨烯、羟基磷灰石和壳聚糖等非金属涂层,未来可以对无机物涂层和高分子涂层进行广泛研究,也可采取更多种不同生物活性元素的组合来提高抗菌性能。目前微弧氧化技术所制备的植入体涂层炎症研究多局限于免疫系统,且集中在巨噬细胞,而其对于中性粒细胞、血小板等的研究稀缺,未来需联合应用多种先进技术手段探究微弧氧化涂层对其他免疫细胞和炎症细胞的具体影响。

Abstract: BACKGROUND: Micro-arc oxidation can effectively add bioactive elements to the metal surface and improve the anti-bacterial and anti-inflammatory properties of biomedical metal materials, so this technology has become one of the hotspots of biomedical materials. 
OBJECTIVE: To summarize the anti-bacterial and anti-inflammatory properties of surface coatings prepared by the combination of micro-arc oxidation and other surface modification technologies. 
METHODS: Articles from January 1996 to December 2022 were searched on CNKI, WanFang and PubMed databases using Chinese and English search terms “micro-arc oxidation, antibacterial properties, anti-inflammatory properties, metal implants”. After preliminary screening according to inclusion and exclusion criteria, 89 articles were retained and summarized.
RESULTS AND CONCLUSION: The ceramic layer prepared by micro-arc oxidation can improve the anti-bacterial and anti-inflammatory properties of titanium, magnesium and other alloys. Combination with other surface modification technologies can effectively solve the effect of pores on the surface properties of the alloy, and further improve the biological properties of the oxide film. It has a wide application prospect in orthopedics and dentistry. At present, most studies are limited to metal coatings, and most of them focus on metal elements with good antibacterial properties such as silver and copper, while only a few studies mention non-metallic coatings such as graphene oxide, hydroxyapatite and chitosan. In the future, extensive studies can be conducted on inorganic coatings and polymer coatings, and more combinations of different bioactive elements can also be adopted to improve antibacterial properties. Currently, studies on the inflammation of implant coatings prepared by micro-arc oxidation are mostly limited to the immune system and focused on macrophages, while studies on neutrophils and platelets are scarce. In the future, a variety of advanced technologies should be combined to explore the specific effects of micro-arc oxidation coating on other immune cells and inflammatory cells.

Key words: micro-arc oxidation, alloy, metal implant, surface modification technology, anti-bacterial property, anti-inflammatory property, immune system, macrophage
