Observation of therapeutic effect of rats with spinal cord injury through HBO and BMSCs transplantation

To observe the therapeutic effect of rats with spinal cord injury through HBO and BMSCs transplantation. Jointly manufacture 60 SCI rat models, which shall be divided into the control group, BMSCs group and treatment group by adopting the random number table, 20 rats for each group. The HBO treatment shall be conducted to the rats in the treatment group for 2 times every day after molding; what's more, the transplantation treatment shall be conducted to the BMSCs group and treatment group after 1 week and 4 weeks respectively, and the equal amount of physiological saline shall be injected to the control group at the same time. BBB motor function scoring shall be adopted for assessment of the hind limb motor function of the rat weekly after molding; kill the rats in the 9th week after molding, and compare the expression situation of the nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) at the injured spinal cord of the rats in various groups. At different time points after molding, it is found that the hind limb motor function of the rats in the treatment group is remarkably better than the other 2 groups (P<0.05); in the 9th week after molding, it is found that the NGF and BDNF protein expressions of the treatment group are remarkably higher than that of BMSCs group and control group (P<0.05). HBO with BMSCs transplantation treatment can remarkably promote the recovery of the hind limb motor function of SCI rat. The treatment mechanism may be related with that HBO promotes BMSCs survival and improves the NGF and BDNF expression of the injured spinal cord.
