1提供免费眼镜对中国学龄儿童学习成绩的影响:整群随机对照试验显示文摘目的探讨免费眼镜对中国农村近视儿童学习成绩的影响。设计仅对研究者进行设盲的整群随机对照研究。地点2012-2013年,中国西部的两个市的252所学校。研究对象在19934名小学四、五年级儿童中的、任一眼裸眼视力〈6/12且戴镜视力可提高至〉6/12的3177名(平均龄10.5岁)儿童,其中的3052名(96.0%)儿童完成了整个研究。干预措施纳入研究的儿童在学年开始时,以学校为单位(平均每组84所学校)随机分为3组,分别接受以下干预:仅获得配镜处方(此组为本研究的对照组),获得项目指定眼镜店换取眼镜的凭证,或现场获取免费眼镜。主要结果指标末次检查(研究结束)时的戴镜率和研究结束时用专门设计的数学测试考核的成绩(用研究开始的成绩进行调整,以标准差的改变来度量)。结果3177名纳入的儿童被随机分配到对照组(1036名,占32.6%)、凭证组(988名,占31.1%)和免费眼镜组(1153名,占36.3%)。虽然所有儿童戴镜后视力均有提高,但在研究开始时,仅15%的儿童配戴了眼镜。研究结束时免费眼镜组观察到的戴镜率为41%,儿童自诉的戴镜率为68%;对照组观察到的戴镜率为26%,儿童自诉的戴镜率为37%。相对于对照组,免费眼镜组对学习成绩影响为0.11标准差(SD)[95%可信区间(CI)0.01—0.21,P=0.03]。调整后的免费眼镜的效应(0.10SD,95%CI0.002~0.19;P=0.04)也远远大于父母的受教育程度(0.03,95%CI-0.04~0.09)及家庭的富裕程度(0.01,95%CI-0.06~0.08)。虽然组间有统计学差异,但差异的幅度还是比用于样本量计算的幅度,即0.20SD小。结论尽管儿童的依从性并不是非常好,向儿童提供免费眼镜对于提高儿童的数学成绩有统计学意义,但各组间差异小于预期。本研究中,儿童的近视患病率较高但戴镜率却很低。马晓晨 周钟强 易红梅 庞晓鹏 史耀疆 陈倩韵 Mirjam E.

9Immunocamouflage of latex surfaces by grafted methoxypoly(ethylene glycol)(mPEG):Proteomic analysis of plasma protein adsorption显示文摘Grafting of methoxypoly(ethylene glycol)(mPEG) to cells and biomaterials is a promising non-pharmacological immunomodulation technology.However,due to the labile nature of cells,surface-plasma interactions are poorly understood;hence,a latex bead model was studied.PEGylation of beads resulted in a density and molecular weight dependent decrease in total adsorbed protein with a net reduction from(159.9±6.4) ng cm-2 on bare latex to(18.4±0.8) and(52.3±5.3) ng cm-2 on PEGylated beads(1 mmol L-1 of 2 or 20 kD SCmPEG,respectively).SDS-PAGE and iTRAQ-MS analysis revealed differential compositions of the adsorbed protein layer on the PEGylated latex with a significant reduction in the compositional abundance of proteins involved in immune system activation.Thus,the biological efficacy of immunocamouflaged cells and materials is mediated by both biophysical obfuscation of antigens and reduced surface-macromolecule interactions.LE Yevgeniya LI Li WANG DunCheng SCOTT Mark D 2012Science China(Life Sciences)2012,55,3:1
