Objective To present the preliminary clinical results of anterior thoracoscopic correction for thoracic idiopathic scoliosis and consider its ind ications. Methods Between June 2002 and May 2003, 8 female patients with a diagn osis of right thoracic idiopathic scoliosis were selected to undergo thoracoscop ic instrumentation, correction and fusion using Eclipse system. The average age at surgery was 14.8 years (ranged from 13 to 16 years). The average preoperative Cobb angle was 54? (ranged fom 40? to 72?). 5 had idiopathic thoracic curves of King type Ⅲ, 2 of King type Ⅱ, and 1 of King type Ⅴ. The Risser sign rang ed from (+++) to (++++). The bending films of the thoracic curves showed a flexi bility of 60%-75%. The thoracic sagittal profiles remained normal without obviou s kyphosis or lordosis. In all cases the rotation of the top vertebra of scolios is was of degree Ⅰ. The operative time, blood loss, postoperative drainage, the number of instrumented levels, curve correction and loss of correction were ana lyzed. Results The instrumented levels were from T5 to T12. The average number o f instrumented levels for each patient was 7.4. The operative time averaged 6 ho urs. The blood loss during surgery averaged 629 ml (ranged from 400 to 800 ml), with no blood transfusions being required, except in one case. The average posto perative drainage was 500 ml. The postoperative Cobb angle was 15? on average w ith curve correction of 74%. With an average follow-up period of 6.5 months (ran ged from 3 to 12 months), the loss of correction averaged 8.3%. No hardware comp lications occurred. Conclusion Compared to the open anterior and posterior surge ry, the thoracoscopic Eclipse instrumentation is a safe and an effective way to correct thoracic idiopathic scoliosis with similar short-term postoperative resu lts. However, challenging issues remain. These included long operative time, hig h technical requirement, relatively limited indication and large radiation expos ure. Again, further research is needed to study its long-term impact.

OBJECTIVETo observe the clinical effect of Sizhi-Xifang in the improvement of postoperative ankle function.

METHODSFrom Jan. 2006 to Mar. 2008,49 patients were divided randomly into treatment group and control group. The treatment group included 16 males and 8 females with an average age of (41.3 +/- 13.2) years, involving 13 cases of tye A, 9 of type B and 2 of type C based on AO classification. The control group included 15 males and 10 females with an average age of (38.2 +/- 10.9) years, involving 12 cases of type A, 10 of type B, 3 of type C. Minimal invasive percutaneous plate were used in each group. In treatment group 24 cases were treated with Sizhi-Xifang after the incisions were healed.

RESULTSThere were no incision infections, flaps necrosis, bone and plate exposure after treatment in two groups. All patients were followed-up for 4 to 16 months with an average of 8.6 months. According to Johner-Wruhs evaluation standard, there were 7 cases in excellent, 12 good, 5 in fair in treatment group and in control group there were 5 cases in excellent, 7 in good, 10 in fair and 3 in poor. The comparison of effect between two groups had significant difference (P < 0.05).

Objective To study the value of lung window and soft tissue window in measuring colon diseases with experimental CTVC examination.Methods Twenty-four artificial polypoid diseases were placed with glue in a thoroughly cleaned porcine colon(overall length,150 era)that was distented with air and submerged in a water phantom and scanned 10 times on a 64-MSCT(GE Light speed)with identical scanning parameters.The data were reconstructed every 0.625 mm and reviewed using 2D images, navigation,MPR and 3D volume-rendered images on a GE AW 4.2 workstation.The maximum diameters of the artificial polypoids were measured by two radiologists with more than 10 years working experience in lung window(W = 1000,L =-700)and soft tissue window(W =400,L =40),respectively.The average value of maximum diameters of the artificial polypoids were measured for 10 times and were compared with the actual diameter.Results Twenty-four artificial polypoid diseases and their shape,size,loeation and relation of diseases with bowel wall were all showed excellently.The maximum diameter measured was close to the actual diameter.The average value was mostly less than actual diameter and a few of them more than the actual diameter.The maximum diameter measured in lung window was close to the actual diameter,and there was no difference between the two data sets(t =0.431,P =0.669).There was difference between the maximum diameter measured in soft tissue window and the virtual diameter(t = 2.691,P = 0.010). Conclusion In screening the colon diseases,CTVC is a good method of choice with no insult or less insult, and higher repeatability.The lung window should be chosen in measuring colon diseases in CTVC examination.

Objective To evaluate the safety,biocompatibility and efficacy of transcatheter closure of atrial septal defect(ASD)with no stainless-steel-screw occluder in canine model.Methods The device was constructed from superelastic Nitinol wires tightly woven into two flat disks and sewed with polyester fibers inside,with a pliable loop on the right-atrial-disk of the device,connecting to the delivery cable.ASD was created by transcatheter puncture and balloon dilatation and then closed by occluder under fluoroscopy in the catheterization laboratory.The location and the influence of the implanted device on function of tricuspid valve and mitral valve were evaluated by echocardiography.At 1,2,3 and 6 months after the operation,the animals were killed and autopsy was conducted.Results Eight dogs with puncture-produced ASD underwent ASD closing procedure successfully.The occluder showed no influence on the function of MV and AV demonstrated by echocardiogram.The two disks of the implanted device were covered with a smooth intact neogenesis layer in all dogs.Endocardial cells fully covered the surface of the two disk without inflammating reaction 3 months later. There was no evidence of corrosion on the surface of the nitinol wire removed from the dog after 6 months.Light microscopic examination of the liver,kidney,lung and spleen showed no evidence of embolization and inflammation.Conclusion Transcatheter ASD occlusion with new-type occluder is safe,feasible,effective and good biocompatibility with a good prospective clinical application.

OBJECTIVETo systematically review the effectiveness of bone substitute augmentation combined with internal fixation versus internal fixation alone in treating proximal femoral fractures in the elderly.

METHODSSubject term and keywords were searched from Pubmed, Cochrane databases and CNKI from database foundation to August 2015. Randomized controlled studies and qusi-randomized controlled studies on bone substitutes augmentation combined with internal fixation versus internal fixation alone for the treatment of proximal femoral fractures in the elderly were chosen. Postoperative re-displacement, re-operation rate, complications (infection and bone ununion), functional outcome, quality of life scores and muscle strength were seen as outcome indicators. Enumeration data were statistical analyzed by risk difference and 95% confidence interval. Measurement data were analyzed by standardized mean difference and 95% confidence interval. If the same measurement data were evaluated by different standards in different studies, standardized mean differences and 95% confidence interval were used. The methods of statistical analysis were used by Cochrane databases.

RESULTSEleven RCTs (677 patients) were included. Meta-analysis results indicated that bone substitutes augmentation combined with internal fixation occurred fewer re-displacement [SMD = -0.75, 95% CI (-1.03, -0.47)] and obtained better function [SMD = 0.40, 95% CI (0.20, 0.59)]. While there were no significant differences in reoperation rate [RD = 0.02, 95% CI (-0.05, -0.09)], pain at 1 week after operation [MD = -1.79, 95% CI (-13.55, -9.96)], pain ranged from 6 to 8 weeks [MD = -7.24, 95% CI (-20.07, -5.59)], postoperative pain at 12 weeks [MD = -0.32, 95% CI (-4.9, -3.55)], muscle strength [MD = 1.25, 95% CI (-6.98, -9.48)], bone ununion [RD = 0.02, 95% CI (-0.01, -0.05)] and postoperative complications [MD = 0.01, 95% CI (-0.03, -0.04)].

CONCLUSIONCompared with single internal fixation, bone substitutes augmentation combined with internal fixation for the treatment of proximal femoral fractures in the elderly less occur re-displacement and could obtain better functional recovery.
