摘要:

活性氧(reactive oxygen species,ROS)是骨组织受损伤后常见的产物。如果ROS不能被及时清除,可在细胞内引发氧化应激,从而对骨组织的再生产生负面影响。近年来,随着研究的深入,能够降低ROS水平的纳米材料在促进骨组织再生方面的作用日益凸显。目前用于降低ROS水平的纳米材料,主要包括经表面修饰和微结构设计的纳米材料、掺杂改性无机材料的纳米材料、功能化聚合物材料及水凝胶、纳米酶材料。但这些纳米材料在临床应用时仍然存在一定局限性,主要原因是其可能具有细胞毒性,且缺乏足够的临床试验数据。该文对利用纳米材料降低ROS水平以促进骨再生的研究进行总结,为未来设计和开发促进骨组织再生的新型纳米材料提供思路。

Abstract:

Reactive oxygen species (ROS) are common products of bone tissue injury. If ROS cannot be removed in time, oxidative stress will be induced in the cells, which will have a negative effect on the regeneration of bone tissue. In recent years, with the deepening of research, nanomaterials capable of reducing ROS levels have shown increasing potential in promoting bone tissue regeneration. Currently, nanomaterials applied to reduce ROS levels mainly include those with surface modifications and microstructural designs, dopant-modified inorganic materials, functionalized polymeric materials and hydrogels, and nano-enzymatic materials. However, the clinical application of these nanomaterials is still limited due to their potential cytotoxicity and the lack of sufficient clinical trials. This literature review summarises the research on the use of nanomaterials to reduce ROS levels to promote bone regeneration and provides ideas for the future design and development of novel nanomaterials in this field.

Key words: nanomaterials, reactive oxygen species, bone regeneration, antioxidant
