Abstract:
BACKGROUND:Spinal cord injury can cause the motor, sensory and autonomic dysfunction below the damaged surface, so the repair of spinal cord injury has been the problem of neuroscience research. OBJECTIVE:To analyze the mechanism, experimental research and clinical application of olfactory ensheathing cel transplantation for the repair of spinal cord injury, and to investigate the effect of olfactory ensheathing cel transplantation on neurological function recovery. METHODS:The basic experimental and clinical researches on olfactory ensheathing cel transplantation for the repair of spinal cord injury were retrospectively analyzed, in order to analyze the relationship between the number and time of the survival cells and the structure and function of the damages spinal cord after olfactory ensheathing cel transplantation. The inclusion and exclusion criteria of the included clinical researches, and the sources, types and transplantation method of the cells used for transplantation were clearly defined, then the effective and objective evaluation criteria was established. RESUTLS AND CONCLUSION:The animal experiments of olfactory ensheathing cel transplantation for the repair of spinal cord injury have achieved satisfactory effects. The spinal cord function score and the sensory and motor function were significantly improved compared with those before transplantation (P<0.001). The successful animal experiment could provide basis for the clinical experiment and application. Parts of the clinical experiments were fol owed-up for 5 years. Because of a smal amount of the cases in the clinical research and the short fol ow-up period, the final recovery of large number of cases cannot judged yet, further observation and research were required. The great significance of the research result is to help to find a reasonable strategy that can make the olfactory ensheathing cells displayed repairing effect sufficiently.
