随着人口不断增加,交通日益发达,中枢神经系统(CNS)损伤的人数急剧上升,CNS损伤后修复非常困难,致残率极高,因此CNS损伤后的再生与修复成为当今研究的热点与难点。但CNS损伤后的再生与修复面临许多问题,主要是损伤后CNS内的环境不利于修复的发生与发展,如损伤后局部以星 With the increasing population and the increasingly developed traffic, the number of central nervous system (CNS) injuries has risen sharply. It is very difficult to repair after CNS injury and the disability rate is very high. Therefore, the regeneration and repair after CNS injury have become hot and difficult issues in current research . However, the regeneration and repair after CNS injury are faced with many problems, mainly because the environment inside the CNS after injury is not conducive to the occurrence and development of the repair,
