0.05).Tight integration was found between the two materials in the two groups and there was no distinct interface examined by SEM.Conclusions:GP-084 cellular silicone elastomer and SY-1 silicone elastomer may be adhered completly.

Objective:To evaluate the effects of surface modified nano titanium-oxide on the mechanical properties of A-2186 silicone elastomers. Methods:Added surface modified nano titanium-oxide into A-2186 silicone elastomers with 0.0%, 0.5%, 1.0%, 1.5%, 2.0%, 2.5% and 3.0% additions according to the ASTM standard. The mechanical properties of A-2186 silicone elastomer including the tensile strength, the broken elongation, the tear strength and the Shore-A hardness were tested separately. The section of samples were investigated by scanning electron microscope and energy spectrum analysis. Used statistics method to analyse the results. The results were analysed with software EPSS 13.0. Results:With the addition of nano titanium-oxide increasing, the tensile strength, the broken elongation and the tear strength of A-2186 silicone elastomers increased firstly, and then decreased. While the Shore-A hardness of A-2186 silicone elastomers increased gradually. When the addition of surface modified nano titanium-oxide reached to 2.0%, the nano titanium-oxide dispersed well in the base without agglomeration. Under such condition, the A-2186 silicone elastomer showed the best general mechanical properties:the tensile strength was (6.54?0.55) MPa, the broken elongation was 618.00?7.58(%), the tear strength was (16.64?0.52) kN/m and the Shore-A hardness was (31.00?0.79) U. Conclusion:The mechanical properties of A-2186 silicone elastomers are improved most greatly with 2.0% addition of surface modified nano titanium-oxide to the base of A-2186 silicone elastomers.

Objective To assess and compare the advantages and disadvantages of five fields of three dimensional conformal radiation therapy(3DCRT),three fields of 3DCRT and the simulator-guided radiation therapy for patients with esophageal carcinoma.Methods Twenty patients with esophageal carcinoma were treated by three dimensional conformal radiation therapy,at the same TPS,three Dimensional conformal radiation therapy target and normal tissue of three radiotherapies were simulated.The treatment planning was five days per week with 1.8～2.0 Gy per fraction。 5 fractions per week,5OGy per 5～6 weeks. Results Compared with simulator-guided radiation therapy,3DCRT planning has better dose distribution and protection of normal tissue. Conclusion Esophageal cancer conformal radiotherapy can reduce the radiation injury of the normal tissue and complications,and improve treatment of conformal radiotherapy and the target dose distribution.

Objective To identify the practical microsurgical procedure for repairing in site of skin avulsion injury in hand, and evaluate the long-term following-up results. Methods From January 2001 to May 2005, 21 cases of skin avulsion injury in hand were treated in our department. The surgical procedures thumb skin was revascularized with vein graft from forearm, and the other part of injuried hand was resuffaced by the thickness skin graft taken from the original degloved skin, which was suitable for degloving injury in-graft, the dorsum and palm of hand was skin grafted by the original skin thinned, which was suitable for complete degloved injury at the proximal interphalangeal level. Results All the repaired skin were survival in 16 patients, partial necrosis occurred in 4 cases, which was severely crushed, required debridement and skin graft on the residual defect. Whole failure in 1 case, which underwent secondary amputation. Follow-up at 10-28 months shows acceptable cosmetic and sensible results, slight scarring was present on the volar as-pects of hand. The range of motion of the thumb and fingers was almost complete. All patients regained new jobs. Conclusion Individualization of mierosurgical methods for repairing in site of skin avulsion injury in hand does represent the best solution.

Objective To evaluate the diagnosis value of plasma Dickkopf-1(DKK1)in hepatocellular carcinoma (HCC)pa-tients.Methods Selected 48 patients with HCC,20 patients with liver cirrhosis (LC),20 patients with chronic hepatitis B (CHB),and all of them were clinically diagnosed in the Third People’s Hospital of Nantong City,chose 20 cases of health examination as healthy controls (HC),that were ruled out other chronic disease.Enzyme-linked immunosorbent assay (ELISA)and Abbott i2000 microparticle chemiluminescence immunoassay analyzer were used to determine the plasma DKK1 and alpha-fetoprotein (AFP)levels.At the same time,analysesed and compared the receiver operating characteristic (ROC)curve and correlation of the DKK1 and AFP results.Results The plasma level of DKK1 in patients with HCC was significantly higher than that in patients with chronic hepatitis B,cirrhosis and healthy controls (Z=-4.132~-5.828,P<0.001).The area under ROC curve (AUC)of plasma DKK1 in the diagnosis of HCC was 0.889 and 95% confidence in-terval was 0.831~0.947,when the Cut-off value of DKK1 was 565 ng/L,the sensitivity was 93.8% and specificity was 70% in diagnosing HCC.The areaunder ROC curve of AFP in the diagnosis of HCC was 0.759 and 95% confidence interval was 0.667~0.850.The AUC of DKK1 was significantly higher than that of AFP (Z=2.28,P=0.022).DKK1 and AFP in diagnosing HCC were no significantly correlated (r=0.148,P=0.316).21 patients with AFP under 20μg/L showed higer DKK1 above 565 ng/L in 48 patients with HCC.Conclusion Detection of DKK1 in plasma can be used as a complement of AFP in the diagnosis of HCC,Especially DKK1 early diagnostic value of AFP negative HCC patients is remarkable.

Objective To summarize the outcome of treatment for thoracic vertebra ossification of ligamentum flavum (OLF)with en-bloc removal of the spinal canal’s posterior wall termed as the “thinned cap uncovering”technique.Methods From 2003 to 2013,56 patients with OLF were treated with thinned cap uncovering technique.In this group,there were 40 male patients and 1 6 female ones,with the average age of 45 years (range of 30-65 years)and the average history of 3 years.The 56 patients were followed up for an average duration of 2 years and 7 months (1-5 years).Results According to WANG’s evaluation,45 cases (about 80%) had excellent results,9 cases (about 1 6%)had good results,and 3 cases had improved symptoms,the excellence to good rates being 96%.Conclusion Removal of the posterior wall of the spinal canal via “thinned cap uncovering”technique is a reliable and effective treatment for thoracic OLF.The strategy for successful operation is to use high speed drill to cut bone accurately,which allows discectomy for thoracic vertebra and to diminish faults and complications during the surgical procedure.

Objective: To study the biodegradable of coral PLA composite artifical bone combined with bBMP or rhBMP as a new kind of bone substitute material. Methods: The composites were implanted into the muscle pouches of mice after combined with rhBMP-2 or bBMP respectively. Ectopic osteoinductive activity of rhBMP-2 or bBMP was examined and compared by histology and histo-morphometry.Results: rhBMP-2 and bBMP had different osteoinductivety. rhBMP-2 appeared to induce less bone and more angioid tissue and marrow. While bBMP seemed to have opposite effects. Conclusion: bBMP is more osteoinductive than rhBMP-2.
