Objective To investigate the correlation between Toll-like receptor2 (TLR2) gene promoter region -597T/C polymorphism and primary ANCA associated small vasculitis (AAV) in Guangxi Han people. Methods A case contrastive control study was adopted in the study. Patients with AAV (patients group, n=110) and healthy people (control group, n = 200) were recruited. Associated serum indexes were detected and polymorphisms of TLR2 gene promoter 597T/C were analyzed by polymerase chain restricted fragment length polymorphisms (PCR-RFLP). Results (1)Three TLR2-597T/C genotypes were discovered in 110 AAV patients, namely, TT, TC and CC, with the frequency of 54.55%,40.00% and 5.45% respectively. And the frequencies of allele T and C were 74.55% and 25.45%. In control group, the genotype frequencies of TT, TC and CC were 56.00%,40.50% and 3.50%, with 76.25% of allele T and 23.75% of allele C. No significant differences were found in neither genotype distribution nor allele frequencies between the patients group and control group ( P > 0 . 05 ) . ( 2 ) Significant differences were found in the incidence of proteinuria rate and the hemoglobin (P< 0.05)in AAV patients. (3)There was no significant difference between AI and CI in TT, TC and CC genotype in AAV patients. Conclusions Polymorphism of TLR2-597T/C may be correlated with the incidence of proteinuria and the level of hemoglobin, while no obvious correlation with the genetic susceptibility of ANCA in vasculitis patients of Guangxi Han people.

Objective To detect the clinical effect of posterior reduction combined with H-shaped bone grafting and spinous process replantation for reconstruction of spinal structures in treatment of thoracolumbar fracture.Methods Forty-three patients with thoracolumbar burst fracture treated surgically from February 2008 to June 2012 were reviewed retrospectively.There were 30 male and 13 female patients aged 23 to 55 years (mean,38 years).Fracture resulted from high falls in 21 patients,traffic accidents in 16 patients,and a crush by heavy objects in 6 patients.Denis system was used for classification of fracture and Frankel rating for assessing the degree of nerve damage and recovery.After posterior reduction combined with H-shaped bone grafting and spinous process replantation for all patients,visual analogue scale (VAS) was utilized to assess symptom improvement and Cobb' s angle and sagittal spinal canal diameter were measured to help assess the treatment outcome.Results Pain was apparently eased at a 24-month follow-up (range,12-46 months).Cobb' s angle improved from preoperative 43.56° to postoperative 8.23° (t =1.33,P ＜ 0.01).CT findings showed mean spinal canal stenosis rate was 56.3％ before surgery and that mean sagittal canal diameter of the injured spine was larger than that of adjacent segments at follow-up,with the mean ratio of 116.3％ (range,111.3％-120.3％).Rate of spinal canal stenosis was negative for all patients and posterior canal with bone grafts healed.Spinal cord injury improved at least one Frankel grade.Conclusion Posterior reduction combined with H-shaped bone grafting and spinous process replantation is worthy of clinical application,for the procedure can restore the fractured thoracolumbar spine and posterior canal structure,but also effectively avoid the iatrogenic spinal stenosis.
