ObjectiveTo compare the short-term efficacy and safety of autologous bone marrow mesenchymal stem cells transplantation on patients with early spinal cord injury by subarachnoid injection and by intravenous injection.MethodsNinety-six patients with early spinal cord injury were hospitalized and treated from November 2006 to March 2010.Thirty-eight cases (subarachnoid transplantation group) got transplantation by subarachnoid injection,32 cases (intravenous transplantation group) got transplantation by intravenous injection,26 cases (control group) were hospitalized in the same period but not transplanted.The motor and sensory functions of all three groups were evaluated according to the score standard developed by American Spinal Injury Association(ASIA) before treatment and at the first,the third,the sixth month after treatment.Meanwhile,routine blood test,coagulation,biochemical items and tumor markers were also examined in follow-up.ResultsThe motor and sensory function of three groups had different degree of recovery at the first month after treatment,and sensory function recovered muchsignificantly,but the comparison among three groups had no statistical significance.The scores of motor function increased in three groups at the third month after treatment,but still had no statistical significance (P＞ 0.05).The scores of sensory function of subarachnoid transplantation group[(130.9 ±41.6) scores] and intravenous transplantation group [ (131.2±22.7 ) scores ] increased obviously,and had significant difference compared with control group [ (109.3±36.4) scores] (P ＜ 0.05),but there were nosignificant difference between subarachnoid transplantation group and intravenous transplantation group (P ＞ 0.05).The scores of sensory and motor function of control group didn't increase obviously at the sixth month after treatment,while the scores of subarachnoid transplantation group and intravenous transplantation group gradually improved and had statistical significance compared with control group(P ＜ 0.05).The scores of sensory function was higher in subarachnoid transplantation group[ (151.6±46.9) scores ] than that in intravenous ransplantation group [(134.6 ±40.7) scores] (P ＜0.05).There were no obvious abnormality in the results of followed-up examination.Conclusions The safety and short-term efficacy of autologous bone marrow mesenchymal stem cells transplantation in treating early spinal cord injury by subarachnoid injection and intravenous injection is certified.The subarachnoid injection is better than intravenous injection,but the long-term efficacy need furter study.

ObjectiveTo explore the short-term curative effect and safety of autologous bone marrow mesenchymal stem cells transplantation in patients with primary brain stem injury.MethodsFifty-four cases with primary brain stem injury were hospitalized during Jul.2007 to Jul.2010 at Liaocheng Brain Hospital,Shandong Province.All cases were randomized into transplantation group( n =30)or control group( n =24 ).The transplantation group was treated with autologous bone marrow mesenchymal stem cell transplantation by subarachnoid space injection (n =30).The control group were selected from primary brain stem injury patients without stem cell transplantation who were hospitalized at the same period with patients from the transplantation group.Respectively,National Institutes of Health Stroke Scale (NIHSS) score was employed to evaluate the condition of patients in the two groups one month after treatment,and Glasgow Outcome Scale (GOS) score was used to evaluate curative effects of the two groups at sixth months after treatment.Meanwhile,some other parameters were observed,including blood routine,clotting mechanisms,biochemicalitemsand tumor markers.ResultsThere was significant difference between the transplantation group and the control group in N IHSS score at one month after treatment [ ( 10.86 ± 7.48) vs.( 18.26 ± 8.74),t =2.681,P ＜ 0.05 ].GOS score was significantly different( Z =2.306,P ＜ 0.05 ) between the transplantation group and the control group at sixth month after transplantation.There was no significant difference between the two groups in the blood examination results during the followed-up period.Conclusion Autologous bone marrow mesenchymal stem cells transplantation is confirmed to be an effective and safe therapy in patients with primary brain stem injury in the short-term.Further evaluation still needs for its long-term efficacy on primary brain stem injury

Objective To investigate the treatment effect of lumbar subarachnoid continuous drainage on delayed hydrocephalus in patients with cerebral trauma after decompressive craniectomy.Methods Thirty-two patients with delayed hydrocephalus after decompressive craniectomy,admitted to our hospital from June 2009 to September 2013,were treated by lumbar subarachnoid continuous drainage;and the treatment effect was analyzed.Results After lumbar subarachnoid continuous drainage,14 patients got successful drainage tube being extracted in the first period,5 were in the second cycle;they all got avoidance ofventriculo peritoneal shunt operation.However,the other 13 patients,developed into shunt dependent hydrocephalus,were treated with ventriculoperitoneal shunt operation.No central nervous system infections were noted during the period of draining.Conclusion The treatment of lumbar subarachnoid continuous drainage,with the characteristics of small trauma and easy operating,can reduce the incidence of shunt dependent hydrocephalus,which is developed by delayed hydrocephalus.
