冠心病（coronary heart disease，CHD）是美国男女人群的主要死亡原因。由于近一半的首次重大冠心病事件见于平时无症状的个体，因此临床医师希望能够采取适当的一级预防措施来准确地辨别“危险”个体。国家胆固醇教育计划（NCEP）成人治疗指南（ATP-Ⅲ）^2依据费明汉危险评分建议所有成人均应到诊所对CHD事件的发生风险进行评估，涉及因素包括年龄、总胆固醇水平、高密度脂蛋白胆固醇（HDL-C）水平、吸烟状况以及收缩压。

目的中国是人口多样化、教育程度差异很大的国家,然而教育程度与我国急性心肌梗死(AMI)患者预后的相关性仍不清楚。本研究旨在探索AMI患者的教育程度与预后的相关性,以期进一步指导未来健康医疗干预的方向。方法研究基于China PEACE前瞻性AMI研究的数据,共纳入来自中国53家医院的3 369名连续入选的AMI患者,并根据其接受教育的程度分为高(高中、大学及研究生)、中(初中学位)、低(小学及小学以下)3个不同水平。采用生存模型分析不同教育程度与AMI后1年严重心血管病不良事件(MACE)发生率和全因病死率的关系,并校正了人口统计学和心血管危险因素等差异的影响。结果研究人群的中位年龄为61(52~69)岁,23.2%为女性,33.3%为高学历水平,32.4%为中等学历水平,34.3%为低学历水平。与高中、大学或研究生学历相比,小学或小学以下学历患者的1年MACE发生率更高(危害比2.41, 95%可信区间1.72~3.37),全因病死率也显著增高(危害比3.09, 95%可信区间1.69~5.65)。在校正人口统计学及共病因素后,教育程度与1年全因病死率的关联减弱(危害比1.41, 95%可信区间0.74~2.69, P=0.30),但教育程度与AMI后1年MACE的关联仍有统计学意义,且学历低的患者的不良事件发生风险是学历高者的近1.7倍(调整危害比1.68, 95%可信区间1.18~2.41, P=0.004)。结论在中国AMI住院患者人群中,教育程度较低的患者在AMI发病1年内发生不良心血管事件和全因死亡的风险更高。将来对AMI患者的健康干预应根据其教育程度的不同,有针对性地完善出院后的宣教和护理,以期改善患者预后。临床试验注册号NCT01624909。

ZnSe/ITO thin films:candidate for CdTe solar cell window layer

引用

Journal of Semiconductors 2017年第9期38卷 14-18页

作者： A.A.khurram M.Imran Nawazish A.Khan M.nasir Mehmood Industrial Technology Development National Centre for PhysicsIslamabadPakistan Materials Science Laboratory Department of PhysicsQuaid-i-Azam UniversityIslamabadPakistan Optics Lab PINSTECHNilorePakistan

The crystal structure, electrical and optical properties of ZnSe thin films deposited on an In203 ：Sn （ITO） substrate are evaluated for their suitability as the window layer of CdTe thin film solar cells. ZnSe thin films of 80, 90, and 100 nm thickness were deposited by a physical vapor deposition method on Indium tin oxide coated glass substrates. The lattice parameters are increased to 5.834 A when the film thickness was 100 rim, which is close to that of CdS. The crystallite size is decreased with the increase of film thickness. The optical transmission analysis shows that the energy gap for the sample with the highest thickness has also increased and is very close to 2.7 eV. The photo decay is also studied as a function of ZnSe film thickness.

关键词： ZnSe thin films ITO substrate XRD optical transmission photodecay
