Rare-earth doped titania single-crystalline hollow nanoparticles of 20 nm are constructed via a simple sol-gel process. Amphiphilic ABA tri-block copolymers played a key role in assisting the formation of hollow structure, for which a hollow nanostructure growth mechanism is proposed. By introducing rare earth into the synthesis process, the as-prepared nanoparticles exhibit near-infrared light absorption properties. Photo-decomposition efficiency of Orange II azo dye can be successfully evaluated when using Yb3+-doped Ti O2 hollow nanoparticles as photocatalysts; it is more than two times higher than the pure Ti O2 hollow nanoparticles. The hollow nanostructured Yb3+-doped Ti O2 samples are exploited as photoanodes in N719- sensitized solar cells and prove able to improve the photoelectric conversion efficiency by measuring the solar cell parameters of dye-sensitized solar cells(DSSCs) under simulative sunlight.

目的系统评价家庭干预对2型糖尿病患者的干预效果。方法计算机检索PubMed、Medline、Embase和Cochrance图书馆,中国知网、万方数据库中关于家庭干预对2型糖尿病患者影响的临床试验研究型文献,文献检索时限为2016年1月至2023年6月。以2型糖尿病患者自我管理行为、体重指数和糖化血红蛋白作为本次Meta分析的结局指标,采用Review Manager 5.3软件进行Meta分析和绘图。对于使用糖尿病患者自我管理行为量表以外其他工具测量自我管理行为指标的文献进行系统综述。结果共检索到1342篇相关文献,有13篇文献纳入分析,共包含1454例研究对象,干预组740例,对照组714例。Meta分析结果显示,与医院-患者的常规二元模式相比,家庭干预的加入有助于提高成年2型糖尿病患者自我管理水平(WMD=5.03,95%CI:4.43~5.63,P<0.001),降低糖化血红蛋白(WMD=-0.77,95%CI:-1.32~-0.21,P=0.007),但是对体重指数的影响不明显(WMD=-0.38,95%CI:-1.04~0.28,P=0.25)。系统综述结果支持家庭干预可以改善成年2型糖尿病患者自我管理行为。结论家庭干预可以改善成年2型糖尿病患者自我管理行为,降低糖化血红蛋白水平。
