All participants underwent routine ophthalmological examination, Humphrey visual field and RNFL examination by using Stratus OCT. Retinal images were obtained by using a retinal camera(Topcon 501X).RAVDs were measured from inferior nasal, inferior temporal, superior nasal and superior temporal arcuates by using IMAGEnet software. Superior, inferior, nasal,temporal and average RNFL thicknesses were *** and RNFL parameters in groups and correlations were analyzed by Mann-Whitney U and Spearmann correlation ***: Only inferior quadrant and average RNFL thickness were detected thinner in the PSX group compared with control group(P =0.009, P =0.038,respectively). No statistically significant difference regarding RAVDs was found between two ***: RAVDs seems to be comparable in the PSX and control group. RNFL is thinner in the inferior quadrant in the PSX group. RNFL thickness and RAVDs show significant correlations in both groups. This correlation doesn’t seem to be specific to PSX.

Let G be a finite simply connected domain in the complex plane C, bounded by a rectifiable Jordan curve L, and let w = φ0 （z） be the Riemann conformal mapping of G onto D （0, r0）：= {E-mail：：｜｜〈 r0}, normalized by the conditions φ0 （z0） = 0, φ＇0 （z0） = 1.In this work, the rate of approximation of φ0 by the polynomials, defined with the help of the solutions of some extremal problem, in a closed domain G is studied. This rate depends on the geometric properties of the boundary L.

本文从中国沪深两市观测到的上市公司中CEO和董事薪酬的趋同现象,综合代理理论和乘员理论等多理论基础,基于薪酬激励和公司治理绩效的关系,考察了董事与CEO之间的合谋、单边激励和共同激励等复杂关系。论文采用2005-2007年度我国上市公司样本池数据,通过混合回归、固定效应回归和敏感性分析等实证检验发现,我国董事与CEO薪酬激励已初步与公司业绩挂钩,但是研究揭示CEO激励走在董事绩效激励前面,董事激励不足问题突出。进一步的研究发现上市公司中CEO薪酬与公司业绩正向相关,董事薪酬对公司业绩没有显著影响;结论认为我国上市公司中董事与CEO关系并非简单合谋或共同激励关系,而是处于CEO选择合适角色或监控得当,董事仍持代理角色,并且其战略指导要弱于监控作用的"单边激励"状况。

The increasing demand for organ donors to supply the increasing number of patients on kidney waiting lists has led to most transplant centers developing protocols that allow safe utilization from donors with special clinical situations which previously were regarded as contraindications. Deceased donors with previous hepatitis C infection may represent a safe resource to expand the donor pool. When allocated to serology-matched recipients, kidney transplantation from donors with hepatitis C may result in an excellent short-term outcome and a significant reduction of time on the waiting list. Special care must be dedicated to the pre-transplant evaluation of potential candidates, particularly with regard to liver functionality and evidence of liver histological damage, such as cirrhosis, that could be a contraindication to transplantation. Pre-transplant antiviral therapy could be useful to reduce the viral load and to improve the long-term results, which may be affected by the progression of liver disease in the recipients. An accurate selection of both donor and recipient is mandatory to achieve a satisfactory long-term outcome.

This article deals with how developed economies, such as those of Japan, South Korea, United States of America （USA）, Russian Federation, China, and the European Union （EU） can threaten world peace. Focusing on economic and social security issues, countries of the world having conflicts will, as a result, invest in military arms, such as nuclear or chemical weapons. How would today＇s economic circumstances, social security systems difficulties, health expenditure levels, and individual pension system realities affect the world in soon time？ Globally, problems were tried to describe with Gestalt understanding from micro level to macro level and attempted to prescribe a solution. How can world economic powers use this challenge as an advantage to create sustainable peace？ May hospital rooms allow people to interact with other world societies, civilization values, cultures through elder people？ As a result beyond of being European centric, Asianism centric, American centric understanding for world peace in the middle of developed economies, Turkic world has rich resources and dynamic population. With Turkey＇s secular understanding, Turkic Healthcare Union （THU） can be a great model for peace. Turkic world, which is located between China and EU, would be a unique and also a sample model in creating sustainable peace. This economic model depends on manufacturing of services and creating prosperity for the whole world, creating funds for ambiguous events in the world, having limited merchants, and making heavier states a bit triggering. By triggering the quality of medical tourism in the world and making dynamic big developed economies, harmless healthcare technologies could be created.

董事会究竟发挥何种作用一直是公司治理争议的焦点问题。本文采用董事会权能对战略咨询和监督控制的双路径结构方程模型(Structure Equation Model,SEM),提出董事会的监控作用表现为以薪酬激励监督CEO为间接手段来改善公司业绩;战略咨询则体现为董事会权能对公司业绩的直接贡献。以中国2005～2007年上市公司样本的测试结果表明:国资委、地方与中央国有控股公司等的董事会薪酬监控作用显著,表现为改善董事和CEO激励不足,"薪酬激励效应"突出,董事权力和治理效果逐年改善,但其战略咨询的治理任务有待加强;私人控股公司董事会的战略和监督二元作用初步凸显,但存在"薪酬挤出效应",公司治理状况呈弱化趋势,CEO监管与激励有待改善。
