目的探讨增殖性糖尿病视网膜病变玻璃体手术中更完全地切除玻璃体，减少玻璃体再出血及再手术的发生。方法对2010年1月至2012年12月在唐山市眼科医院就诊的334例415只眼增殖性糖尿病视网膜病变手术患者作回顾性分析，术中均填充平衡盐溶液（BSS液），观察术后6个月内再次出血及再手术情况。将就诊病人分为2组，一组术中未行曲安奈德（TA）染色，二组术中行TA染色，观察统计术后再出血、再手术情况。结果TA染色后可以更好地切除玻璃体，减少了术后再出血及再手术的发生率。结论TA染色在增殖性糖尿病视网膜病变玻璃体手术中是可以应用的一个手术方法，可以减少术后并发症的发生，减少再手术的风险。

More and more attentions have been attracted by lithium-sulfur batteries(li-S), owing to the high energy density for the increasingly advanced energy storage system. While the poor cycling stability, due to the inherent polysulfide shuttle, seriously hampered their practical application. Recently, some polar hosts,like single metal oxides and sulfides, have been employed as hosts to interact with polysulfide intermediates. However, due to the inherent poor electrical conductivity of these polar hosts, a relatively low specific capacity is obtained. Herein, a spinel-type bimetal sulfide NiCo_(2)S_(4)through a Prussian blue analogue derived methodology is reported as the novel host of polysulfide, which enables highperformance sulfur cathode with high Coulombic efficiency and low capacity decay. Notably, the li-S battery with NiCo_(2)S_(4)-S composites cathode still maintains a capacity of 667 m Ah/g at 0.5 Cafter 300 cycles, and 399 m Ah/g at 1 C after 300 cycles. Even after 300 cycles at the current density of 0.5C, the capacity decays by 0.138% per cycle at high sulfur loading about 3 mg/cm;. And the capacity decays by0.026% per cycle after 1000 cycles, when the rate is 1C. More importantly, the cathode of Ni Co_(2)S_(4)-S composite shows the outstanding discharge capacity, owing to its good conduction, high catalytic ability and the strong confinement of polysulfides.

为探究目前服装橱窗视觉效果对消费者情绪、认知与购买意愿的作用机制,以环境心理学(S-O-R)模型为基础,以服装实体门店橱窗作为评价对象展开实证研究。结果表明:橱窗视觉效果不能直接影响消费者购买意愿,而情绪维度的唤醒和认知维度的品牌态度均能作为单中介及链式双中介影响购买意愿;橱窗视觉效果能够直接或通过唤醒情绪的中介作用影响感知产品质量与品牌态度,但不能通过愉悦情绪与感知产品质量影响购买意愿。基于以上结果,为品牌服装橱窗展示提供了优化方向与参考建议。

土地利用变化影响陆地系统碳循环过程。在实现碳中和目标的背景下,分析区域碳平衡,优化土地利用结构具有现实意义。以河南省为例,以1 km网格为单元,应用InVEST碳固存模块、IPCC碳排放核算、人口密度法等方法,研究1995、2005、2015年区域碳平衡的时空变化。结果表明,研究区固碳服务的供需量与土地利用类型密切相关。固碳服务的供需在空间存在错配关系,即需求高的地区通常具有较低的供给。研究时段内,研究区的总碳固量逐年下降,总碳排放量逐年增加,研究区碳平衡表现为整体向好,局部恶化的情况。在碳平衡分析的基础上提出了空间优化利用建议,可为未来国土空间规划碳平衡目标的实现提供参考。
