摘要:


文题释义:

生物活性玻璃:由SiO2,Na2O,CaO和P2O5等基本成分构成,这种人工复合材料生物相容性好且机械稳定性强,其降解产物能够促进生长因子的生成、加速细胞的增殖、增强成骨细胞的基因表达和骨组织的生长,是迄今为止唯一既能够与骨组织成键结合,同时又能与软组织相连接的人工生物材料。
缓释离子:是指从生物活性玻璃等材料中缓慢释放出的离子,这些离子具有促进骨组织生长、抗菌和抗炎等生物学效应。研究缓释离子的释放规律和生物学效应,有助于设计具有特定功能的生物材料。


背景:生物活性玻璃是一种多功能人工复合材料,可与组织亲和后缓释活性离子并表现一定的生物活性,其多样性源于制备工艺和组分的多变性,使其能够应用于不同的临床场景。

目的:综述目前生物活性玻璃的主要应用形式、应用领域以及掺杂不同元素对其功能的影响。
方法以“生物活性玻璃,缓释离子,骨组织工程,复合支架,组织再生修复,生物医学工程”为检索词在中国知网及万方医学网检索;以“Bioactive glass,Slow-release Ions,Bone Tissue Engineering,Composite Scaffold,Tissue Regeneration and Repair,Biomedical Engineering”为检索词在PubMed和Web of Science数据库检索自2000-2023年收录的相关文献,最终纳入88篇文献进行综述。

结果与结论:①在应用形式方面,生物活性玻璃可以根据不同临床场景的需要制作成包括涂层、颗粒、骨水泥及支架等形式,其中涂层能提高植入物生物活性,但易因降解导致植入物不稳定;颗粒适用于不规则骨缺损的修复,但传统方式制备的颗粒功能单一;骨水泥具备微创及可注射的优点,但不适用大尺寸骨缺损;支架具备优异的机械性能,常用于较大尺寸骨缺损,但韧性有限。②在应用领域方面,生物活性玻璃可用于包括口腔科、骨科、软组织工程以及癌症等多种组织再生修复和疾病治疗领域。③在元素掺杂方面,特定元素掺入生物活性玻璃后,不仅能提升其机械性能,还赋予了它特殊生物学功能,如生物活性、可降解性和抗菌性等。④生物活性玻璃作为一种多功能材料,可通过调整制备工艺和元素掺入来实现不同的应用形式和功能,满足不同的骨组织工程等临床需求,广泛应用于生物医学工程领域。

Abstract: BACKGROUND: Bioactive glass is a multifunctional synthetic composite material that releases active ions slowly and exhibits certain biological activities after affinity with tissues. Their versatility stems from the versatility of their preparation processes and components, allowing them to be applied in different clinical scenarios. 
OBJECTIVE: To review the main application forms, application fields of bioactive glass, as well as the influence of doping different elements on its function.
METHODS: A literature search was conducted across WanFang Medical Database, CNKI Database, PubMed Database, and Web of Science Database, using the search terms “bioactive glass, slow-release ions, bone tissue engineering, composite scaffold, tissue regeneration and repair, biomedical engineering” in Chinese and English. The timeframe was limited from 2000 to 2023. Finally, 88 articles were included for review.
RESULTS AND CONCLUSION: (1) In terms of application forms, bioactive glass can be fabricated as coatings, particles, bone cements, and scaffolds according to needs. Coatings have the potential to enhance the biological activity of implants, yet they are susceptible to instability as a result of degradation. Particles offer a viable solution for the repair of irregular bone defects; however, particles produced through traditional methods often possess limited functionality. Bone cement provides the benefits of minimal invasiveness and injectability, yet its application is restricted to smaller bone defects. Scaffolds exhibit excellent mechanical properties and are commonly used for larger-sized bone defects, yet they have limited toughness. (2) In terms of applications, bioactive glass can be used in a variety of tissue regeneration and repair and disease treatment fields, including dentistry, orthopedics, soft tissue engineering, and cancer. (3) In terms of element doping, the addition of specific elements to bioactive glass not only improves its mechanical properties but also endows it with special biological functions such as bioactivity, degradability, and antibacterial properties. (4) Biologically active glass is a versatile material that can be used in different forms and functions by adjusting the preparation process and element doping to meet various clinical needs in bone tissue engineering and is widely used in the field of biomedical engineering.
