Dear Editor,rnThe coronavirus disease 2019 (COVID-19) pandemic caused by widespread infection with the severe acute respiratory syndrome eoronavirus 2 (SARS-CoV-2) (Chen et al., 2020;Guan et al., 2020) has led to a global health crisis.More than 3.5 million infections and 246,838 deaths have occurred as of May 4, 2020 (Saqrane and El Mhammedi,2020), with a rapid upward trend.Many COVID-19 patients suffer from complicated systemic injuries such as cardiac (Chen et al., 2020) and hepatic (Huang et al., 2020) damages.There are currently no specific drugs on the market to treat COVID-19-induced systemic injuries (Ni et al.,2020).A study by our group has demonstrated that hydroxychloroquine (HCQ) administration dramatically reduces the fatality of critically ill COVID-19 patients (Yu et al.,2020).In the present study, we investigated whether HCQ treatment has the ability to protect multiple organs from injuries caused by SARS-CoV-2.

章学诚方志学理论及其纂修《湖北通志》的实践对清中期以来湖北方志编纂产生了重要影响。伴随新思想传入,晚清时期方志编纂发生诸多变化,这些变化通常被视为近代方志转型的前奏。在该背景下,清末围绕着《湖北通志》的纂修问题出现了主新派和主旧派的争论。通志纂修以县志编纂为基础,通志纂修的争论往往在县志编纂中有集中的表现。光绪二年(1876)和光绪八年两版《麻城县志》在编纂理念、编排方式和部分内容上的差异可以视为是这一时期相关变化、争论和分歧的缩影。通过对两版县志编纂差异的考察,将有助于我们理解清末方志编纂者如何对新、旧
方志最重要的特性是区域性,又称地域性。新方志编纂尤其强调记载内容有地域范围限制,要以时间下限内所处行政区划的地情为依据。行政区划体系的核心是层级,周振鹤在通观2000年层级变化过程基础上,提出我国政区可归纳为高层政区、统县政区和县级政区三个层次。
