| 1 | WHO生存质量评估简表的等价性评价显示文摘目的评价WHO生存质量评估简表(WHOQOL-BREF)在13个国家的等价性。方法采用多组验证性因子分析方法,对世界卫生组织生存质量研究小组提供的13个国家的数据进行分析,评价WHOQOL-BREF不同国家的等价性。结果各个国家的各个领域的Cronbachα系数均大于0·7,分布在0·7至0·88之间。除了英国和挪威之外,其它国家的社会关系领域的Cronbachα系数均大于0·65。采用根据世界卫生组织生存质量研究小组研制量表时构建的四因子模型对数据分别进行拟合,拟合优度指数(CFI)均大于0·8,其中德国、西班牙和美国的拟合优度指数大于0·9。多组验证性因子分析发现模型拟合尚可,CFI等于0·88,各个国家的因子负荷不全相等,因子负荷的轮廓相似。结论WHOQOL-BREF在13个国家具有相同的因子结构,且有等价性。 | 郝元涛 方积乾 Power M J 吴少敏 朱淑明 | 2006 | 中国心理卫生杂志2006，20，2： | 278 |
| 2 | 美国心脏协会/美国卒中协会急性缺血性卒中血管内治疗早期管理指南(2015年版)显示文摘自"急性缺血性卒中早期管理指南2013年版"发布以来,出现了大量关于急性缺血性卒中血管内治疗的高质量证据[1]。本版更新的指南主要基于2013年以来8项血管内治疗随机临床试验和其他相关数据的分析结果,同时兼顾了2013年指南的证据,并非对上版指南后的文献作全面回顾,而是依据最新的证据作出推荐。本指南与既往指南的重叠部分,以本指南的推荐为准。 | Powers WJ Derdeyn CP Biller J 吴川杰 薛芳 焦力群 朱凤水 | 2015 | 中国脑血管病杂志2015，12，10： | 11 |
| 3 | Computed tomography and patient risk:Facts,perceptions and uncertainties显示文摘Since its introduction in the 1970s, computed tomography(CT) has revolutionized diagnostic decision-making. One of the major concerns associated with the widespread use of CT is the associated increased radiation exposure incurred by patients. The link between ionizing radiation and the subsequent development of neoplasia has been largely based on extrapolating data from studies of survivors of the atomic bombs dropped in Japan in 1945 and on assessments of the increased relative risk of neoplasia in those occupationally exposed to radiation within the nuclear industry. However, the association between exposure to low-dose radiation from diagnostic imaging examinations and oncogenesis remains unclear. With improved technology, significant advances have already been achieved with regards to radiation dose reduction. There are several dose optimization strategies available that may be readily employed including omitting unnecessary images at the ends of acquired series, minimizing the number of phases acquired, and the use of automated exposure control as opposed to fixed tube current techniques. In addition, new image reconstruction techniques that reduce radiation dose have been developed in recent years with promising results. These techniques use iterative reconstruction algorithms to attain diagnostic quality images with reduced image noise at lower radiation doses. | Stephen P Power Fiachra Moloney Maria Twomey Karl James Owen J O'Connor Michael M Maher | 2016 | World Journal of Radiology2016，8，12： | 7 |
| 4 | 补充抗氧化剂对急性心脑血管意外的老年病人血浆抗氧化剂水平的影响显示文摘目的:观察补充外源性抗氧化剂对急性心脑血管意外老年病人血浆谷胱甘肽过氧化物酶(GSH-Px)的活性、维生素A(VitA)、维生素C(VitC)、维生素E(VitE)和硒(Se)水平的影响。方法:对105例急性心脑血管意外老年病人随机分为试验组(加用抗氧化剂)和对照组(服用安慰剂)。两组病人均每天服用1次,连续6周。两组病人在治疗前、治疗后3周和6周,清晨空腹采取肘静脉血3 ml。检测血浆GSH-Px活性、VitA、VitC、VitE和Se的水平变化。结果:治疗3周和6周后,试验组病人血浆GSH-Px活性,VitC、VitE和Se水平较对照组明显升高(P<0.05)。试验组病人治疗6周后VitA水平较对照组明显升高(P<0.05)。结论:对急性心脑血管意外老年病人补充外源性抗氧化剂,可在短时间内增加血浆VitA、VitC、VitE、Se的含量和GSH-Px的活性。 | 李青 史琳娜 樊俊 Hilary J Powers | 2010 | 肠外与肠内营养2010，17，4： | 4 |
