同种异体半关节移植治疗股骨远端肿瘤

目的 对大段异体骨移植用于骨肿瘤保肢治疗及其相关问题进行分析讨论。方法采用大段异体骨修复骨肿瘤瘤段切除后骨缺损5例，术后X线及同位素骨扫描评定骨愈合，并评估其功能恢复情况。结果手术后3—6个月在X线片显示牢固的生物固定（坚强的外骨痂或已骨性连接）、^99mTc—MDP骨扫描图像显示异体骨早期代谢活跃，2年后逐渐恢复正常。结论 同种异体骨半关节移植治疗股骨远端肿瘤术后观察移植骨与自体骨愈合，关节功能重建方面到达良好表现。     

Survivin在非小细胞肺癌中的表达及其与p53、细胞凋亡的关系

目的探讨Survivin基因在非小细胞肺癌（NSCLC）中的表达及其与p53、细胞凋亡的关系。方法采用免疫组化方法检测60例NSCLC和16例肺良性组织中Survivin和p53的表达，用TUNEL技术检测NSCLC的凋亡情况。结果肺癌组织中Survivin蛋白表达的阳性率为63.3％（38／60），而在良性肺疾病肺组织均无表达；Survivin蛋白的表达与肺癌TNM分期、淋巴结转移和细胞分化程度有密切关系，但与肿瘤组织学类型、患者年龄及性别无关。p53蛋白表达阳性的NSCLC中，Survivin蛋白表达阳性率（80．5%）明显高于p53蛋白表达阴性者（26．3％）．P〈0．01。Survivin蛋白在NSCLC中的表达水平与癌细胞的凋亡指数（AI）星负相关（r=-0．231，P〈0．05）。结论Survivin基因异常表达引起的细胞凋亡抑制在NSCLC的发生中起一定作用，抑癌基因p53失活和Survivin基因过度表达可能在NSCLC癌变中起协同作用。

Fabrication of uniform urchin-like N-doped NiCo2O4@C hollow nanostructures for high performance supercapacitors

Transition metal oxides are commonly used in electrochemical energy storage materials, but there are still many drawbacks that impede a wide range of applications. Heteroatom doping can significantly improve its performance. Herein, we have successfully prepared highly uniform N-doped NiCo₂O₄@C hollow nanostructures for supercapacitors by a two-step hydrothermal treatment associated with successive annealing process. Prepared N-doped NiCo₂O₄@C materials exhibited an admirable specific capacitance of 1028 F g⁻¹ at a current density of 3 A g⁻¹, with 625 F g⁻¹ remaining even at high current density of 20 A g⁻¹. Besides, this composite showed good electrochemical stability with capacity retention of 84% after 5000 cycles repetitive galvanostatic charge–discharge test at 10 A g⁻¹. An asymmetric supercapacitor was assembled by the N-doped NiCo₂O₄@C electrode, attached activate carbon (AC) as a counter electrode, exhibiting a high energy density of 26.67 W h kg⁻¹ at a power density of 402 W kg⁻¹. The improvement of electrochemical performance is ascribed to the co-doping of nitrogen and carbon atoms. These results indicate that N-doped NiCo₂O₄@C can be employed as an ideal electrode material for electrochemical energy storage.

A first-principles calculation of structural,mechanical, thermodynamic and electronic properties of binary Ni–Y compounds

The intermetallic compounds between rare earth (RE) elements and transition metal elements have been comprehensively researched due to their appealing magnetic, electronic, optical and thermal properties, in which Ni–Y alloys are one kind of important system. In this work, a systematic investigation concerned with structures, elastic, and thermodynamic properties of Ni₁₇Y₂, Ni₅Y, Ni₇Y₂, Ni₃Y, Ni₂Y, NiY, Ni₂Y₃ and NiY₃ in Ni–Y systems is implemented by means of first-principles calculations. NiY has the lowest formation enthalpy within −0.49 kJ per mol per atom. Ni₅Y has the largest bulk modulus, shear modulus and Young''s modulus of 181.71 GPa, 79.75 GPa and 208.70 GPa, respectively. Furthermore, the effects of different concentrations of yttrium on the mechanical and thermal properties of Ni–Y compounds are estimated by using the Voigt–Reuss method. The electronic density of states and chemical bonding between Ni and Y are key factors that determine mechanical and thermodynamic properties of these compounds. What''s more, results indicate that all compounds are dynamically stable as shown by the calculated phonon dispersions.
