[Objective] To investigate the therapeutic effect of early anterior bone grafting and internal fixation after focal cleaning and vertebral canal decompression for the treatment of tuberculosis of thoracolumbar vertebrae. [ Methods ] A retrospective study was carried out in 26 patients with thoracolumbar vertebral tuberculosis (TVT) who received early anterior bone grafting and internal fixation after focal cleaning and vertebral canal decompression. After treatment, the therapeutic effect was evaluated by observing the recovery of nerve function. [Results] The result of a follow-up ranging from 8 months to five years and 4 months showed that all the cases wi vertebral tuberculosis were cured, free from relapse. The internal fixation and bone graf(?)ing for fusion were good, and nerve function recovered, maintaining a good state. The nerve function of six patients with incomplete paralysis fully recovered. [Conclusion] Early anterior bone grafting and internal fixation after focal cleaning and vertebral canal decompression are effective to promote the recovery of nerve function of TVT patients. This regimen is capable of relieving or preventing spinal compression promptly, rebuilding the stability of the spine and presenting the focal diffusion, beneficial to the recovery of the patients.

Objective To explore the clinical effect of renal artery embolization for renal graft dysfunction.Methods A total of 17 patients with renal graft dysfunction were treated by embolizing the renal graft artery.Coil embolization was performed on 7 of the cases,and gelfoam combined with coil was used in the other 10.Results Among the 17 patients,14 discontinued immunosuppressant in 3 weeks after the embolization,and 2 discontinued after receiving low-dose cortisones for about 6 months,and showed good recovery during follow-up.The other patient underwent resection of the renal graft because of continuous fever and graft pain.After the embolization,14 cases developed 'post-embolization syndrome'.Coil migration occurred in 1 case during the procedure.One patient experienced angina during the operation,and developed myocardial infraction the day after the embolization.Conclusions Renal artery embolization is safe and effective for patients with renal graft dysfunction.By using the method,open surgery can be avoided.Attention should be paid to potential complications.

[Objective] To investigate the effect of SKY expander vertebroplasty and KYPHON vertebroplasty for compression fracture of thoracic/lumbar vertebral body. [Methods] Twenty-one patients (group A) with compression fracture in 27 thoracic/lumbar vertebral bodies were enrolled to this study. Among them, 17 fractured vertebral bodies from 15 patients received SKY expander vertebroplasty and another 10 fractured vertebral bodies from 6 patients received KYPHON vertebroplasty. Thirty-three patients (group B) with compression fracture in 35 thoracic/lumbar vertebral bodies receiving conservative treatment during the same period served as the control. After treatment, the therapeutic effect and result of X-ray image were compared in the two groups. [Results] A follow-up ranging from 1 month to 11 months showed that pain in the loin and back, decrease of vertebral height, complications of leaking of bone cement, and bed sore (which occurred in group B) were not found in the patients receiving vertebroplasty. [Conclusion] SKY expander vertebroplasty and KYPHON vertebroplasty are effective and safe for compression fracture of thoracic/lumbar vertebral body, which can relieve the back and loin pain as soon as possible, reconstruct the vertebral body, decrease the occurrence of complications and promote the rehabilitation, and have a better effect than conservative treatment. For the two kinds of vertebroplasty, SKY expander vertebroplasty is economic and indicated for single vertebral fracture and old fracture, and KYPHON vertebroplasty is indicated for multiple vertebral fracture, severe fracture, and vertebral body fracture with end-plate broken.

Objective:To revise the Chinese version of Devereux Early Childhood Assessment for Preschool-ers,Second Edition (DECA-P2 ),and assess its validity and reliability.Methods:Totally 608 children aged 3 -5 years were rated by their teachers with the Chinese version of DECA-P2 and two criterion scales,which included the Chinese version of Preschool Behavioral and Emotional Rating Scale,and Social Competence and Behavior Evalua-tion Scale-30.Data of 570 were valid.After identifying valid items using item analysis,exploratory factor analysis was performed for half of all samples.Confirmatory factor analysis was also conducted with another half samples.Moreover,the present study tested criterion-related validity,internal consistency reliability and split-half re-liability of the Chinese version of DECA-P2.Results:Through the exploratory factor analysis,the obtained structure of protective factors was the same as the original scale,accounting for 59.82%of the variance.The results of con-firmatory factor analysis achieved the standard of psychometrics (χ2/df=2.50,RMESA=0.07,CFI=0.91,IFI=0.91).Generally,each subscale had significant correlation with the two criterion scales (r=-0.21 ~0.80). Be-sides,the Cronbach αcoefficients of all subscales were between 0.80 and 0.93,and the split-half reliabilities of them were between 0.79 and 0.89.Conclusion:The Chinese version of DECA-P2 has acceptable psychometric quality and can be applied to evaluate resilience for children aged from 3 to 5 years in China.

Objective To investigate pulmonary infect flora distribution characteristics of stroke patients with tracheotomy in Intensive care unit (ICU) and analyze the risk factors.Methods A total of 792 cases of ICU stroke patients was selected,including 426 cases of tracheotomy patients,and 366 cases of non-tracheotomy patients.The incidence of lung infections was compared.Bacteriological examination was used for tracheotomy bacteriological studies for lung infected stroke patients with tracheotomy.Bacteria infection's characteristics was observed.The risk factors were analyzed.Results (1) The tracheotomy patient 's lung infection rate was 23.00％,higher than 9.56％ of the non-tracheotomy patients,the difference was statistically significant (X2 =19.125,P ＜0.05);(2) For lung infection-occurred patients with tracheotomy of ICU,gram-negative bacteria infection rate was 63.97％,significantly higher than 19.85％ of gram-positive bacteria and 16.18％ of fungi,the difference was statistically significant (x2 =18.255,17.042,P ＜ 0.01);(3) Lung infection rate of ICU stroke tracheotomy patients with unconscious,dysphagia,hospitalization time ＞ 14 d,blood glucose levels ≥≥7.8 mmol/L,and based diseases was significantly higher than that of patients with conscious,non-dysphagia,hospitalization time ≤＜14 d,blood sugar level ＜7.8 mmol/L,and no based diseases (P ＜ 0.05);(4) Consciousness,dysphagia,hospitalization,blood sugar levels,and the underlying disease were the independent risk factors of lung infection in ICU stroke tracheotomy patients (OR1 =11.528,OR2 =8.046,OR3 =15.174,OR4 =7.795,ORs =10.784,P ＜0.05).Conclusions Gram-negative bacteria is the main reason for pulmonary infections in ICU stroke tracheotomypatients patients with stroke.State of consciousness,invasive treatment,hospitalization,blood sugar levels,and the underlying disease are the independent risk factors.

Objective To compare different susceptibility testing methods of tigecycline against Acinetobacter baumannii and Klebsiella pneumoniae.Methods Fifty carbapenem-resietant A.baumannii (CRAB) strains and 49 K.pneumoniae strains were collected from Tianjin Medical University General Hospital during January and March 2012.Minimum inhibitory concentration (MIC) and inhibitory zone diameters for tigecycline were determined by broth microdilution,Vitek-2,MTS and disk diffusion methods.The results of Vitek-2,MTS and disk diffusion methods were compared with those of broth microdilution method.Results According to FDA standards,the susceptibilities of CRAB and K.pneumoniae to tigecycline determined by broth microdilution,Vitek-2 and MTS were 94.0％/91.8％,68.0％/91.8％ and 90.0％/91.8％,respectively.For CRAB isolates,the essential agreement (EA) and categorical agreement (CA) produced by Vitek-2 and MTS were 94.0％/72.0％ and 92.0％/90.0％.MICs determined by Vitek-2 were 1-2 dilutions higher than the reference method in 33 (66.0％) strains,and those determined by MTS were higher in 16 (32.0％) strains and lower in 11 (22.0％) strains.For K.pneumoniae isolates,the EA/CA produced by Vitek-2 and MTS were 95.9％/98.0％ and 83.7％/91.8％,respectively.MICs determined by Vitek-2 were 1-3 dilutions lower than the reference method in 17 (34.7％) strains,and those determined by MTS were 1-3 dilutions lower than the reference method in 39 (79.6％) strains.None of thetwo methods produced very major error (VME) and major error (ME) against two kinds of isolates.The results were determined by disk diffusion method using different breakpoints according different isolates.For CRAB,using ≥14 mm/≤ 10 mm as breakpoint,CA was 94.0％,which was higher than the breakpoint recommended by Jones et al (≥16 mm/≤12 mm,CA was 82.0％) ; and for K.pneumoniae,using the ≥ 14 mm/≤ 10 mm as breakpoint,CA was 93.9％,higher than the FDA Enterobacteriaceae breakpoint (≥ 19 mm/≤ 14 mm,CA was 67.3％).Conclusion For CRAB strains,MTS produces better consistence with broth microdilution,with several higher or lower MIC results.For K.pneumoniae strains,Vitek-2 has better correlation with reference method,with several lower MIC results.The consistence between disk diffusion method and broth microdilution is comparatively lower,and the breakpoint should be adjusted according to different bacteria.
