ABSTRACT
ObjectiveTo investigate the preventive strategy of early post-operative complications of closed spinal dysraphisms in children.MethodsOne hundred and nine children with closed spinal dysraphisms underwent surgery from January 2004 to December 2008,were enrolled in this study.After dural closure,the wound was washed completely with saline to clear the tissue debris to prevent postoperative infection. We routinely made a horizontal incision to prevent postoperative infection. Results After operation,all patients were recovered and were discharged from hospitalNo post-operative complications,including cerebrospinal fluid leakage, wound infection and flap necrosis, were encountered. ConclusionThe sophisticated microsurgical technique and the delicate surgical manipulation is the prerequisite for the prevention of early operational complication of closed spinal dysraphisms in children.
ABSTRACT
Objecttive To observe the repaired effect of distinct source olfactory ensheathing cells (OECs) on spinal cord injury (SCI) rats. Methods These OECs were dissociated from olfactory bulb and olfactory mucosa of SD rats and transplanted to the injuried region of spinal cord injury rats. The function of nerve, motor evoked potential of hind legs and the histopathlogical diversities of injuried spinal cord were observed. Results The OECs grafts into the SCI area could survive longer time. The BBB scale, incubation stage of EP and histopathologic manifestations showed that the group with transplanted OECs regained more improvement in hindlimb than the control group. Conclusion The OECs of two sources have the same ability to regain and improve the axonal function which can promote axons regeneration of SCI.
ABSTRACT
[Objective]To evaluate the clinical treatment results for diastematomyelia treated by operation. [Method]Data from patients with diastematomyelia admitted to our hospital from May 1978 to January 2006 were reviewed. According to the classification, there were single-tube in 25 and double-tube in 96 patients. One hundred and two patients with diastematomyelia were treated by operation and ninteen by conservative treatment. The clinical results were retrospectively analyzed according to scoring neural function and monitoring the peak P40 of posterior trivial nerve cortical somatosensory evoked potential (PTNCSEP) before and after treatment.[Result]The total operative effective rate of double-tube diastematomyelia amounted to 86% during a follow-up period of 6 months to 15 years,more significant in patients with pain.The scores of neural function and PTNCSEP were significantly improved. But patients with single-tube diastematomyelia had no obvious change after operation.[Conclusion]The spinal cord is damaged severely in double-tube diastematomyelia and gradually aggravated.Operation can get symptomatic relief in many patients and terminate spinal cord lesion. So operation should be performed as soon as the diagnosis is made. The spinal cord is damaged slightly in single-tube diastematomyelia and surgery is not indicated.
