| 摘 要： | <正>The primary function of the peripheral nerves is to transmit signals from the spinal cord to the rest of the body,or to convey sensory information from the rest of the body to the spinal cord.In case of injury or a health disorder,this pathway can be partially or totally disrupted,resulting in pain,loss of sensation,reduced muscular strength,poor coordination,or complete paralysis.Even if peripheral nerves can spontaneously regenerate from injury,in the case of a complete nerve transection,a clinical operation must be performed in order to reconnect the portions of the injured axons.Although current clinical strategies include autografts,allografts and nerve guides,the maximum regeneration distance is limited to 25 mm.Researchers are currently focused on finding new methods and materials to improve this nerve regeneration distance in the case of gap
