Spinal cord injury rehabilitation is an important part of rehabilitation medicine. The clinical education of graduates in spinal cord injury specialty is complex and unique. The graduates' incorrect learning methods and poor academic basis are dominant factors that will influence the teaching quality. And the teachers' poor professional knowledge will lead to the failing of meeting the requirements of clinical teaching and will influence the teaching quality. The teachers should make individualized teaching plan based on the student's academic background, clinical basis and degree level. In clinical practice, the teaching departments should improve their hardware and software condition. The clinical teachers should try to improve their professional level and teaching skills by intensifying the self-education. The graduate students should make modification and innovation in learning methods according to their own problems.

Objective To compare the difference of the spinal cord injury rehabilitation physician training systems between Harvard Uni-versity and Capital Medical University. Methods The spinal cord injury rehabilitation physician training systems of Capital Medical Univer-sity and Harvard University were investigated, including the degree training time, residence training time, training fee and institution. Re-sults Degree education time was more in the basic science in Harvard University than in Capital Medical University. The residence training time was 7 years and 5 years for Harvard University and Capital Medical University, respectively, and the ratio of specialties and sub-spe-cialties was not significantly different. There was a total of 26 spinal cord injury community rehabilitation clinics in Harvard University sys-tem, and none in Capital Medical University. Conclusion Some light can be drawn from the spinal cord injury rehabilitation physician train-ing system of Harvard University, to improve the scholastic building of Capital Medical University.

Objective To apply the three dimensional reconstruction thoracolumbar pedicle anatomical parameters in spine surgery pedicle screw implantation. Methods 6 healthy specimen spines were chosen and three dimensional spine reconstruction was based on 2 mm CT scan of the spines. The anatomical parameters including length and angle parameters were calculated based on the three dimensional reconstruction images. Results The pedicle width of T9～L4 was 4.68～8.70 mm, and increased gradually from T9 to L4. But the pedicles width of T12, L1 and L2 were smaller than the others. The pedicle height of T9～L4 was 8.19～12.76 mm. There was no significant difference from T9 to L4. The pedicle height of T12 was the biggest among them. The pedicle transverse angle was from 6.26 º to 13.06 º and increased gradually from T9 to L4. But for the pedicle sagittal angle, the difference is not obvious and most of them are in the range of ±5 º. Conclusion Three dimensional reconstruction and calculation of thoracolumbar pedicle can show the anatomical characteristics of the spine and provide evidence for individual pedicle screw implantation.

Objective To discuss the modification of the ASIA scale (version 2011) and the significance for clinical practice. Methods Through comparing the newest English version of ASIA scale to the previous version, we tried to find the difference between them and interpret the possible influence on clinical practice. Results The study found that there were 15 modifications found after comparing the two versions of scales. Some modifications were just descriptive, some were for emphasis, and the others were fundamental modification. Conclusion The ASIA Committee makes prudent modification according to the advice of the doctors worldwide in the past ten years to make scale more applicable for clinical practice. The modification will influence the neurological examination of spinal cord injuries in clinical practice and relative research

Objective To investigate the effects of short-segment pedicle screws system on type A thoracic and lumbar spine fracture with or without pedicle screws on the fractured level. Methods 23 patients with type A thoracic and lumbar spine fracture were included, in which 11 cases received traditional short-segment pedicle screws system without pedicle screws on the fractured level (group A), and other 12 cases with pedicle screws on the fractured level (group B). The anterior vertebral height, posterior vertebral height and local kyphosis an-gle were measured before and after operation. Results All pedicle screws were successfully implanted with good location and stability. The vertebral height and kyphosis angle significantly improved after operation in both groups (P<0.05), and the improvement of kyphosis angle was more in group B than in group A (P<0.05). Conclusion Short-segment pedicle screws system with pedicle screws on the fractured level may fine correct the kyphosis angle in short term.

ObjectiveTo evaluate the early rehabilitation outcome of the spinal cord stab injury (SCSI).MethodsThe materials of 40 SCSI patients and 50 contusion spinal cord injury (CSCI) patients from 1992 to 2004 were analyzed retrospectively. The curative effects were evaluated with ASIA scale (modified in 2000) and FIM scale.ResultsAfter comprehensive rehabilitation treatment, scores of ASIA and FIM scales of SCSI patients increased and significantly higher than that of CSCI patients (P<0.05～0.01).ConclusionThe SCSI patients shall be treated with comprehensive rehabilitation in early stage and their prognosis will be better than CSCI.

ObjectiveTo observe the effect of surgical management on the thoracolumbar Chance fracture.Methods12 cases with thoracolumbar Chance fracture who accepted surgical management were followed-up 12 to 42 months(the mean was 21 months). ResultsDistraction deformity of posterior element were reduced significant in all patients, meanwhile, compression of anterior column was restored. Neurological function of all incomplete paraplegia patients improved their ASIA classification at least one grade. ConclusionSurgical treatment and internal fixation were suitable for stabilization of Chance fracture, neurological recovery and early rehabilitation.

ObjectiveTo investigate the concurrent and predictive validity of ASIA2000 motor scale.MethodsConsecutive observation was done to the 42 patients who were admitted in CRRC from September 2003 to September 2004.ASIA motor score and conventional motor score were recorded respectively 1 month and 3 months after injury.ResultsPearson correlation coefficient between the MDP of the two systems was 0.945,while that of the MRP was 0.897.ConclusionThe ASIA2000 motor score has good validity.

Neurogenic detrusor overactivity (NDO) often occurs after spinal cord injury, which often causes urinary tract infection, vesi-coureteral reflux, or even renal failure, and seriously impacts on the patient's quality of life. This paper reviewed the mechanism, the com-mon treatment methods, and neuromodulation theray of NDO after spinal cord injury, and elaborated percutaneous posterior tibial nerve stimulation, pudendal nerve regulation and the sacral neuromodulation respectively.

Objective To investigate the effect of basic fibroblast growth factor (bFGF) on the synthesis of extracellular matrixc (ECM)and expression of chondromodulin in human intervertebral disc cells. Methods 4 intervertebral discs (IVDs) obtained from patients in thetreatment of disc degenerative disease were used for cell culture. The secondary generation of intervertebral disc cells were cultured for 7days, then different concentration of bFGF (0, 0.1 ng/ml, 1 ng/ml, 10 ng/ml)were added to the medium and treated for 72 hours. Real-timeRT-PCR was used to detect the change of Aggrecan and type Ⅱ collagen mRNA expression. The effect of FGF on the expression of ChM-1,a cartilage derived anti-angiogenic factor, was also used by means of Real-time RT-PCR and Western blot. Results Real-time RT-PCRshowed that bFGF can significantly inhibit the expression of Aggrecan and type Ⅱ collagen mRNA. Both Real-time RT-PCR and Westernblot showed that the expression of ChM-1 was down-regulated by administration of bFGF with dose-dependent way. Conclusion bFGFserves primarily as a catabolic factor and induce the angiogenesis in the process of intervertebral disc degeneration.
