RESUMO
BACKGROUND:The connection between high-level central nervous system and spinal cord and peripheral nerve under injury level is blocked by traumatic spinal cord injury,and the whole function of the body is thereby influenced.The loss of motor function and feeling both severely affect the patient's life quality in views of physiology,psychology,function and social economics.RNA interference is an effective method to silence target genes,which provides a new treatment strategy for spinal cord injury.OBJECTIVE:To explore the application status of RNA interference in spinal cord injury.METHODS:PubMed and CNKI databases were retrieved using the keywords of "RNA interference,RNAi,spinal cord injury" in English and Chinese,respectively.The articles addressing the application of RNA interference in spinal cord injury were collected and reviewed.RESULTS AND CONCLUSION:Totally 44 articles were enrolled.It is urgent to find a new way to treat spinal cord injury.Compared with the traditional gene silencing technology,RNA interference owing to high specificity,high efficiency,high stability and high penetrability is considered to be a new direction for the studies on the pathogenesis and treatment of spinal cord injury.
