文题释义:
磁性骨水泥:以磁响应物质与骨水泥基质合成的骨水泥,能在修复骨缺损的同时,利用磁响应物质在交变磁场中产热实现肿瘤局部热疗,杀灭肿瘤细胞,最终达到降低骨肿瘤局部复发的目的,具有一次置入、反复使用及温度可控等优点。
磁热疗:磁响应物质在交变磁场中吸收电磁波,将电磁能转化为热能,利用肿瘤细胞较正常细胞对热敏感的机制,杀灭肿瘤细胞,实现肿瘤局部热疗。
 
 
背景:磁性材料是磁性骨水泥的关键组成部分,随着磁性纳米颗粒在射频磁场中产热机制的深入研究,生物相容性好、产热效能高的纳米颗粒成为向临床转化的研究目标,以不同成分、比例磁性纳米颗粒与骨水泥基质合成的磁性骨水泥,在理化性能、体外及体内生物相容性、热疗疗效等方面出现很多新的研究成果。
目的:综述磁性骨水泥研究进展。
方法:由第一作者应用计算机检索PubMed、Web of science、EMbase、万方数据库关于磁性骨水泥、磁热疗研究的文章,磁性骨水泥选择关键词为“Magnetic bone cement”,磁热疗选择关键词为“Magnetic hyperthermia”,两者采用逻辑运算符“AND”连接。

结果与结论:磁性骨水泥由磁响应物质和骨水泥基质构成,磁响应物质由微米级铁氧体颗粒逐渐向纳米级铁氧体颗粒发展,其原因在于产热效能的提升,产热效能的提高有利于降低磁性骨水泥中磁性材料的质量百分比,相应地骨水泥的力学强度、凝固时间等理化性能,体内、外的生物毒性、热疗疗效等也随之发生改变。低毒、高产热效能磁性骨水泥是目前研究方向,在未来磁性骨水泥可能不仅需具有磁热疗的作用,同时还需兼备化疗、放疗,甚至免疫治疗作用,多功能磁性骨水泥可能会成为骨转移瘤的新型填充材料。

Abstract:

BACKGROUND: Magnetic materials are the crucial part of magnetic bone cement, with the explicit investigation of the heating emission mechanism of nanoparticles in magnetic radio-frequency fields, magnetic nanoparticles with good biocompatibility and high heating efficiency may become the hotspot for clinical transformation. Magnetic bone cement consist with magnetic nanoparticles with different ingredient, ratio and bone cement matrix, there are many research progresses in physicochemical property, in vitro and in vivo biocompatibility, heating efficiency and the hyperthermia effect.
OBJECTIVE: To review the research progress of magnetic bone cement.
METHODS: The articles about magnetic bone cement and magnetic hyperthermia were retrieved from PubMed, Web of science, Embase and WanFang databases. The keywords were “magnetic bone cement, magnetic hyperthermia”. The logical operator between them was “AND”.
RESULTS AND CONCLUSION: Magnetic bone cement consists of magnetic materials and bone cement matrix, the magnetic materials were chosen from micron ferrite particles to nanoscale ferrite particles, because of the increasing of heating efficiency. Consequently, the mass percent of magnetic materials in magnetic bone cement will decrease with the increasing of heating efficiency. Then, the physicochemical property, such as, mechanical strength, and setting time, in vitro and in vivo biocompatibility, and hyperthermia effect change. The bone cements with low toxicity and high heating efficiency are the main research direction. In the future, magnetic bone cement will not only preserve the function of hyperthermia, but also have the function of chemotherapy, radiotherapy and immunotherapy. Multi-functional magnetic bone cement may become a new filling material to treat bone metastasis.

Key words: bone cement, magnetic bone cement, magnetic hyperthermia, magnetite nanoparticles, tumor hyperthermia, nanoscale ferrite particles, metastasis
