1Extractability and Mobility of Copper and Zinc Accumulated in Sandy Soils显示文摘Extractability and mobility of Cu and Zn and their relationships with 1) accumulation of Cu and Zn and 2) soil pH were studied in three sandy soils (Wabasso, Ankona, and Winder) from commercial citrus groves in Florida, USA. The soils, with a broad range of Cu and Zn concentrations, were fractionated by a modified procedure of Amacher, while Cu and Zn mobility were evaluated using column leaching. The extractability of Cu and Zn increased with decreasing soil pH. Also with increasing total soil Cu and Zn for extractable Cu in the Wabasso sand a threshold level, where the metal extraction rate increased, was noted at 100 mg kg-1, whereas for extractable Zn in the Wabasso sand the threshold level was found at 60 mg kg-1 and in the Ankona sand at 120 mg kg-1. These results suggested that the release potential of Cu and Zn was greater in the Wabasso sand than in the Ankona sand. The column leaching experiment showed that at total soil Cu or Zn concentrations < 100 mg kg-1 all leachates had low Cu and Zn concentrations. However at total concentrations > 200 mg kg-1 for Cu and > 150 mg kg-1 for Zn with decreasing soil pH, the concentrations of both Cu and Zn in the leachates increased exponentially. Also in these sandy soils soluble Cu and Zn mainly originated from the exchangeable fractions, and pH was a key factor controlling Cu and Zn extractability and mobility.ZHANG Ming-Kui HE Zhen-Li D.

2随机对照试验中的患者报告结局:CONSORT PRO扩展版显示文摘临床试验报告规范CONSORT(Consolidated Standards of Reporting Trials,CONSORT)声明旨在提高随机对照试验(randomized controlled trail,RCT)的报告质量,然而该声明却缺少专门关于患者报告结局(patient-reported outcomes,PROs)的指引,而这部分内容恰恰也是临床试验经常报告不足的内容。患者报告结局指标数据的缺失影响了临床试验结果的价值。本文报告了依据'提高医疗卫生研究的质量和透明度协作网'(EQUATOR Network)所提出的报告规范研发方法学框架制定的临床试验报告规范—CONSORT患者报告结局扩展版(CONSORT PROs)。最终推荐5个CONSORT患者报告结局清单条目,用于以患者报告结局为主要或关键的次要结局指标的随机对照试验。这些推荐条目强烈要求:(1)在摘要中需明确说明将患者报告结局作为主要或次要结局指标;(2)提供针对患者报告结局指标及其相关适用范畴的假设(如是否使用了多维度患者报告结局指标的检测工具);(3)提供或引用患者报告结局测量工具效度和信度的证据;(4)明确说明处理缺失数据的统计学方法;(5)讨论以患者报告结局指标为研究结果指标的特定局限性和结果对其他人群和临床实践的影响。本文还提供了相关条目的示例和附有患者报告结局的CONSORT流程图。建议在报告以患者报告结局作为主要结局指标或关键的次要结局指标时,以CONSORT患者报告结局扩展版与原版的CONSORT报告规范相互参考进行报告。改进后的患者报告结局试验数据将大大促进对随机对照试验结果的全面解释,并较好指导患者的治疗。陈泽(翻译) 陈珏璇(翻译) 段玉婷(翻译) 张弛(回译) 陈耀龙(审校) 卞兆祥(翻译) Calvert M Blazeby J Altman DG 2021中国循证医学杂志2021,21,3:5
