BACKGROUND:Thoracolumbar fracture becomes more in the clinic. The fixation manner of thoracolumbar fracture is controversial. Injured vertebra pedicle screw fixation or traditional cross-segment pedicle screw fixation are controversial and lack the support of evidence-based medicine. OBJECTIVE: To evaluate the outcomes of injured vertebra pedicle screw and cross-segment pedicle screw fixation for thoracolumbar fractures. METHODS: According to Cochrane system evaluation, the folowing databases were retrieved: National Library of Medicine database, China National Knowledge Infrastructure, Wanfang database and VIP database. Conference proceedings were searched by hand. The retrieval time ranged from 2005 to March 2015. Randomized controled trials were colected. Meta-analysis was performed by using Cochrane Colaboration Revman 4.2. RESULTS AND CONCLUSION: By screening, a total of 14 clinical controled trials were selected, including 956 patients. Meta-analysis results showed that postoperative Cobb angle was improved significantly in the vertebral pedicle screw group than in the cross-segment pedicle screw fixation group (OR=-2.72, 95%CI:-3.08--2.35,P < 0.01). Correction rate of the vertebral height was higher in the vertebral pedicle screw group than in the cross-segment pedicle screw fixation group (OR=7.45, 95%CI:6.94-7.97,P < 0.01). The failure rate was lower in the vertebral pedicle screw group than in the cross-segment pedicle screw fixation group (OR=0.12, 95%CI: 0.05- 0.27,P < 0.01). Results verify that postoperative Cobb angle improved significantly after the injured vertebrae pedicle screw and cross-segment pedicle screw fixation for thoracolumbar fractures. The height was obviously corrected and fewer complications were caused such as implant failure. The fixation effect was good.

Objective To probe the feasibility of gemstone spectral CT in imaging pulmonary angiography with low dose contrast medium.Methods A prospective study with multi-slice spiral CT pulmonary angiography was performed in consecutive 48 patients suspected with pulmonary embolism.Two groups (n=24 respectively)were divided at random including Group A used Gemstone spectral CT with 35 mL of contrast medium and Group B using 64-slice CT with conventional 80~90 mL of contrast medium.The CT values of the pulmonary trunk,lobe artery,pulmonary vein and ascending aorta were measured.The contrast to noise ratio of the pulmonary artery was also calculated.In addition,the image quality of CTA was evaluated independently by two experienced ra-diologists.Results The CT values of the pulmonary trunk and the subsegmental branches,and the CNR in Group A were signifi-cantly higher than those in group B,exhibiting statistical differences (t=8.6,P <0.001;t=12.2,P <0.001;t=1 1.3,P <0.001 respectively).However,the CT value of aorta in Group A was significantly lower than that in Group B (t=-7.6,P <0.001).The evaluation results of the CTA images by two radiologists showed that the image quality in Group A was better than that in Group B (Z =-8.6,P <0.001;Z =-9.0,P <0.001 ).Conclusion The image quality of pulmonary angiography with gemstone spectral CT using low contrast medium dose can be improved compared with the conventional spiral CT.

Objective To investigate the correlation of microperimetric parameters,best-corrected visual acuity (BCVA) and central retinal thickness (CRT) in diabetic macular edema (DME) eyes.Methods It is a prospective,no controlled,open study.Twenty-four consecutive patients (40 eyes) with DME were included.There were 10 males (18 eyes),14 females (22 eyes);aged from 41 to 79 years,with the mean age of (56.84±8.96) years.All the patients were type 2 diabetes,the average duration of diabetes was 8 years.BCVA was evaluated using the international Snellen E vision test chart,and then recorded as logarithm of the minimum angle of resolution (logMAR).CRT was measured by Cirrus HD-OCT4000.MAIA microperimetric parameters were evaluated,including average threshold (AT) of retinal sensitivity,macular integrity index (MI),fixating points within a circle of 1° (P1) and 2° of radius (P2),bivariate contour ellipse area (BCEA) considering 63％ and 95％ of fixating points (A63,A95),and horizontal and vertical axes of that ellipse (H63,H95,V63,V95).Pearson correlation analysis was performed to evaluate the association between these variables.The independent factor influenced the type of fixation was analyzed by multiple linear regression analysis.Results Strong correlations of logMAR BCVA with CRT (r=0.58,P=0.000),V63 (r=0.44,P=0.004),V95 (r=0.41,P=0.008),MI (r=0.36,P=0.024),AT (r=-0.61,P=0.000),P1 (r=-0.41,P=0.009),P2 (r=-0.38,P=0.015) were found.AT was correlations with P1 (r=0.53,P=0.000),P2 (r=0.51,P=0.001),A63 (r=-0.39,P=0.012),A95 (r=-0.40,P=0.012),V63 (r=-0.53,P=0.000),V95 (r=-0.46,P=0.003),MI (r=-0.50,P=0.001).There was no correlation between AT and CRT (r=-0.21,P=0.190).Forty eyes were included in this study,8 eyes (20％) had stable fixation,14 eyes (35％) had relatively unstable fixation,18 eyes (45％)had unstable fixation.Multiple linear regression analysis showed that fixation classification was independently affected by P 1.Conclusions In DME eyes,logMAR BCVA was positively correlated with CRT,negatively correlated with AT,P1 and P2.There is no correlation between AT and CRT.The fixation classification was independently affected by P 1.
