The combination of horseradish peroxidase(HRP)and a fluorescence substrate has been attracting great interests in developing sensitive biochemical analysis and immunoassays.10-Acetyl-3,7-dihydroxyphenoxazine(ADHP or Amplex red)is the most sensitive fluorogenic substrate known for HRP in current market,however,it suffers from some drawbacks,such as non-specific reactivity to carboxylesterase and limited fluorescence *** the present study,a novel HRP substrate10-cyclopropylcarbonyl-dichloro-dihydroxyphenoxazine(AR-2),has been prepared,which exhibited improved sensitivity than ADHP in sensing ***,the fluorescence of AR-2/HRP demonstrated improved tolerance to physiological relevant p H fluctuation as compared to ADHP/*** detection of uric acid/urate oxidase reaction indicated excellent application prospect of AR-2/HRP for monitoring H_(2)O_(2)-generating biochemical *** interestingly,an enzyme-linked immunosorbent assay(ELISA)using AR-2 as the fluorescence reporter has been successfully used in detecting IgG against severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)from human serum ***,AR-2 exhibits improved performances over the commercial ADHP,which will be an ideal alternative to ADHP in HRP-based fluorescence biochemical analysis and immunoassays.

作者：周荣复旦大学古籍整理研究所(中国古代文学研究中心)

朱熹《诗集传》在明代的衍生著作大体有四种类型。其中删节本以删削朱注为主要编纂方式,取便初学是其重要考量;删选本取舍篇目、章句的原则,兼顾了科考的出题偏重和诗篇的辞章性;增注本摭拾众说,或辅翼、或辩证朱《传》,客观上推动朱子... 详细信息

朱熹《诗集传》在明代的衍生著作大体有四种类型。其中删节本以删削朱注为主要编纂方式,取便初学是其重要考量;删选本取舍篇目、章句的原则,兼顾了科考的出题偏重和诗篇的辞章性;增注本摭拾众说,或辅翼、或辩证朱《传》,客观上推动朱子《诗》学的扩容与突破;拼合本对朱《传》进行二次改造,组合各类《诗》说文本以提供更为丰赡的经学知识和应试指导。明人不断增、删朱《传》的文本内容,又热衷于变换其外在形式,主要目的是服务于科举制度下的广大学《诗》阶层。朱《传》从宋到明的衍变轨迹,折射出近世《诗》学教育普及化的历史进程,亦反映出与之相关的科举教习、书籍流转及商业出版等复杂历史情境。

在明初的乡村治理理念中,乡里制度是以里甲制为中心的综合多功能体,蕴含了丰富的社会管理、教化、治安等功能,也蕴含了巧妙的慈善功能。鳏寡孤独残疾有养、婚姻丧葬有助等慈善目标被融于官方的礼法体系和里甲编排等制度安排中。明中叶以后,社会分化加剧,里甲面临瓦解,部分职能废弛,有识之士在重整乡村秩序的过程中,借重的依然是明初的乡治理念。以乡约为中心的保甲、社仓等制度设计成为明代中后期基层治理和慈善救助的主要内容,保甲、乡约、社仓、社学“四合一”是明中后期理想的乡治模式。由于明代乡村治理中贯穿了精神与物质、慈善与控制相结合的原则,基层社会得以在较长时间中维持相对稳定的秩序。
