中文摘要：

良好的生物材料，可以替代人体自身相关组织或者器官，支持相应的机体功能，同时可以加速机体的自我修复和自愈过程。生物材料应用于临床，不仅需要具备与机体器官或组织相匹配的理化特性和生物力学性能，还应与机体组织具有良好的生物相容性和使用安全性。文章回顾了近年来生物材料及其生物相容性研究的某些进展以及在胸心外科领域的应用现状。

英文摘要：

A nice biomaterial, which could replace the correlated tissue or organic of human body,supports the homologous function of organism, and accelerates the process of self recovery and autotherapy in the same time. The application of biomaterial in clinic, not only have the chemical characters and function of vito- dynamics to match, but also be with nice biocompatibility and practical safety. Some development of biomaterial and the biocompatibility of it in this paper was reviewed, and the application status in the cardiothoracic surgery in recent years.
