Objective To explore changes of gray matter volume in patients with obsessivecompulsive disorder (OCD) in Chinese Han population using optimized voxel-based morphometry (VBM) ,and investigate its relationship with clinical symptoms. Methods Twenty patients with OCD and 20 age,sex and handedness matched healthy controls were scanned using 3D-T1 images on a 3.0 T MR system. The high resolution T1WI was preprocessed according to the optimized VBM protocol in Statistical Parametric Mapping (SPM5). Two-sample t test was performed to characterize the differences of the gray matter volume (GMV) between the OCD patients and healthy controls, and the correlations between the GMV and symptom severity and cumulative illness duration were examined using Pearson correlation in SPSS 16. 0, respectively.Results Compared to controls, OCD patients demonstrated increased GMV in left thalamus, right thalamus and left cerebellum after false discovery rate (FDR) correction. No areas of significantly decreased GMV was observed in OCD patients in relative to healthy controls. The mean eigenvalue ranged from 0. 5782 to 0. 889 representing the left thalamus volume of OCD patients was 0. 6813 ± 0. 0718, and that ranged from 0. 5546 to 0. 9062 was 0. 6869 ± 0. 0808 tor right thalamus. The mean eigenvalues were positively correlated in bilateral thalamus (r = 0. 94, P ＜ 0. 01). Conclusion Using optimized VBM, the current research indicates that the pathophysiology of OCD is associated with GMV abnormalities not only in corticostriato-thalamo-cortical (CSTC) circuit, but also in the cerebellum.

ObjectiveTo explore the change of spino-pelvic parameters following pedicle subtraction osteotomy (PSO) for thoracolumbar kyphosis secondary to ankylosing spondylitis(AS).MethodsTwenty-one AS patients with thoracolumbar kyphosis,who underwent PSO at L1 level from July 2006 to October 2010 in our hospital,were retrospectively reviewed.There were 18 males and 3 females with a mean age of 35.6 years (range,21-53 years).The pre- and post-operative thoracic kyphosis(TK),lumbar lordosis (LL),globe kyphosis (GK),angle of the fusion levels (AFL),sagittal imbalance (SVA),pelvic incidence (PI),sacral slope (SS) and pelvic tilting (PT) were measured.ResultsSignificant differences were observed in terms of the improvement of LL,PT,SS,SVA,GK and AFL (P＜ 0.01).The alteration of LL showed significant correlation with the change of PT (r=0.59,P=0.005),SS (r=0.64,P=0.002),SVA (r=0.49,P=0.025),and AFL (r=0.60,P=0.004).The change of PT exhibited cardinal correlation with the change of SS(r=0.94,P=0.000).The improvement of AFL significantly correlated with the improvement of SS(r=0.61,P=0.003),PT (r=0.59,P=0.005).ConclusionThe change of the sagittal spino-pelvic profile following PSO in AS-related thoracolumbar kyphosis is closely related with the improvement of LL.

Objective To investigate the preoperative evaluation of pulmonary function and protocol for scoliotic patients with respiratory failure. Methods From September 2000 to June 2008, sixteen patients suffered from respiratory failure were recruited into this study. There were two males and three females who were diagnosed as idiopathic scoliosis with a mean age of 13.5 years (range, 10-16 years). The other eleven patients were diagnosed as congenital scoliosis, including five males and six females with a mean age of 12.4 years (range, 10-14 years). The mean preoperative Cobb angle was 126.6°±15.5° with a mean height of 137.6 cm (range, 120-160 cm) and a mean weight of 32.5 kg (range, 18-40 kg). Decision was made depending on the severity of pulmonary impairment and spinal deformity. Preoperative treatment included respiratory training, noninvasive positive pressure ventilation therapy and halo-gravity traction. Results All patients received corrective surgery; ten patients were extubated tracheal tubes successfully 1 hour after surgery and six patients had to stay in intensive care unit (ICU) for 24 hours. Pulmonaryedema occurred in two cases and pneumonia in one case. The Cobb angle had improved to 72.0°±13.2° after surgery with a correction rate of 43%. All patients recovered well after surgery with no major cardiac or pulmonary complications.Conclusion Patients with preexisting respiratory failure can tolerate deformity correction operation with few complications after receiving a set of preoperative respiratory training modalities.

Objective To prospectively explore the techniques and correction results of the method of vertebral coplanar alignment (VCA) in posterior correction for thoracic scoliosis. Methods Between June 2008 to March 2009, 27 patients with idiopathic thoracic scoliosis were selected to undergo posterior pedicle screw fixation with assistance of Coplanar system. There were 26 females and 1 male with the average age of 15.9 years(ranged 11-23 years). There were type 1 in 25 cases and type 2 in two cases. The levels of fusion were established according to the Lenke criteria. The average preoperative coronal Cobb angle was 49°(ranged 40°-70° ). During the procedure, the pedicle screws were inserted in each involved levels on the convex side, an extended Coplanar tube was screwed in line with screw axis to each screws. Then two rigid bars were inserted through the uppermost part of the slotted tube sequentially. As the bar was gently driven down toward the bottom end, the pedicle screws axis started to converge in the straight line, correcting translation and rotation. Spacers were inserted into the slots of the tubes to achieve the ideal physiologic thoracic kyphosis. Once the rod was fixated in the concave side of the main curve, the Coplanar system could be removed. Results The mean postoperative Cobb angle was 14° (ranged 6°-25°), representing the correction rate of 70.7%. The average duration of surgery was 245 min (ranged 210-300 min) and a mean estimated blood loss was 1500 ml (ranged 600-2100 ml). The duration of follow-up averaged 15 (12-18) months. The loss of correction at last follow-up was 3° with the loss of correction rate of 6.1%. In the sagittal plane, the thoracic kyphosis was restored from 18° to 25°. No coronal or sagittal plane decompensation occurred. No thoraeoplasties were necessary to correct the residual rib hump. There was no death, infection and neurological complications. Conclusion The Coplanar is a new technique for the correction of scoliosis, its advantage lies in excellent and modulatable three-dimensional correction with a single and standardized maneuver.
