因具有大量的晶界和离子扩散通道,低结晶度的电极活性材料有望在储能领域中实现更好的性能.然而在大多数应用中通常是结晶良好的样品具有更好的稳定性,稳定性较差限制了低结晶样品在相关研究领域的应用.本文利用一种溶剂热法调控N-甲基吡咯烷酮和水混合溶剂的体积比以合成低结晶度的镍钴氢氧化物(NiCo-OH-L).研究发现,将合成的镍钴氢氧化物用作镍-锌电池正极时,NiCo-OH-L不仅表现出与高结晶度的同类样品相当的循环稳定性能,而且在1-50 A g^(-1)的电流范围内显示出更高的容量以及容量保持率.其优异的电化学性能可归因于低结晶的结构,显著提高的比表面积和降低的电荷转移电阻.此外,NiCo-OH-L的钴组分进一步提高了倍率和循环稳定性能.NiCo-OH-L在1 A g^(-1)时的比容量达到238.9 mA h g^(-1),当电流密度升至50 A g^(-1)时的容量仍有116.4 mA h g^(-1),显示出高容量和高倍率性能.不仅如此,由NiCo-OH-L组装成的镍-锌电池在不同的电流和循环周期下也表现出较高的性能.

Herbal medicines have recently been recognized as the second most common cause of drug-induced liver injury （DILI） in the United States. However, reliable methods to identify the DILl causality of some herbs, such as Heshouwu （dried root ofPolygonum multiflorum）, remain lacking. In this study, a total of 12 307 inpatients with liver dysfunction and 147 literature-reported cases of Heshouwu DILI were screened. A general algorithm indicated that only 22.5% （9/40） and 30.6% （45/147） of all hospitalization and literature case reports, respectively, demonstrate the high probability of DILI causality of Heshouwu. By contrast, 95% （19/20） of all cases prospectively investigated by pharmacognosy, phytochemistry, and metabolomic tests exhibited highly probable causality, including a patient who was previously incorrectly attributed and a case that was excluded from Heshouwu causality by pharmacognostic evidence. Toxin （heavy metals, pesticides, and mycotoxins） contamination was also excluded from Heshouwu DILI causality. The objectivity of these screening methods for Heshouwu DILI diagnosis addresses safety concerns regarding stilbene-containing herbal medicines and dietary supplements.

目的了解贵州省老年结核病患者多重用药负担及其影响因素,为减轻患者用药负担提供参考依据。方法2022年4-7月,采用便利抽样法在贵州省贵阳市、毕节市、黔东南苗族侗族自治州三地的3所结核病定点医院抽取405例老年结核病门诊患者作为调查对象,采用一般情况调查表、用药生活问卷(LMQ)进行面对面调查。运用描述性分析、单因素方差分析、多元线性回归分析了解老年结核病患者的多重用药负担得分情况并探讨影响老年结核病患者多重用药负担的因素。结果405例老年结核病患者的多重用药负担总得分为(112.65±14.59)分,高于LMQ高负担标准的阈值(110分)。多元线性回归分析结果显示,年龄80~92岁、自费+医保、复治、耐药、有药物不良反应是老年结核病患者多重用药负担的危险因素(P<0.05);居住地为城镇和服药管理方式为家庭成员管理、志愿者管理、智能工具辅助管理是其保护因素(P<0.05)。结论贵州省老年结核病患者的多重用药负担较重,且受患者年龄、居住地、药费支付方式、治疗分类、是否耐药、药物不良反应、服药管理方式的影响。医护人员应根据多重用药负担的影响因素为重点人群提供用药指导和帮助,以减轻其多重用药负担。
