域外汉籍中存在着大量中国典籍的汉文写本。这些写本或为中国失传的文献,或与传世之本多有差异。域外汉文写本可以成为中国古代文学研究的新领域,其中中国文集日本写本与古代文学研究的关系最为密切。中国文集日本写本在日本公立图书馆、大学图书馆、公私文库、寺院以及个人手中皆有收藏。自江户时代开始,学者就已经注意到这批文献的价值,《佚存丛书》《古逸丛书》《京都帝国大学文学部景印旧钞本》等丛书中皆有收录。晚近以来,学术界对中国文集日本写本也进行了整理与研究,但仍有大量文献未进入研究视野。应尽快展开对中国文集日本写本全面的调查、编目与叙录,并从“东亚汉文写本学”与书籍史的角度对其进行整体研究,同时深入对五山时代中国文集汉文“抄物”写本的研究。

The risk of infection following consumption of foodborne pathogens contaminated foods became a significant concern for human health and imposes great economic losses to food industry. Herein， Ag nanoparticles were integrated to Cu-based metal–organic framework (Cu-MOF) for antibacterial activity. The crystal structure， morphology and composition of the prepared composite Ag@Cu-MOF were confirmed by XRD， TG， SEM， TEM， FTIR and XPS analysis. Antibacterial assays revealed that Ag@Cu-MOF exhibited increased inhibitory activity against Escherichia coli O157:H7 in comparison to Cu-MOF. Ag@Cu-MOF treated bacterial cells displayed distinct morphological changes， a decreased ratio of Live/Dead cells， as well as a reduction of intracellular adenosine 5’-triphosphate (ATP). Antibiofilm studies demonstrated that Ag@Cu-MOF could dramatically inhibit biofilm formation and disrupt preformed biofilms by interfering the metabolic activity and decreasing the expression of biofilm-associated genes. Food contamination model illustrated that Ag@Cu-MOF significantly prevented the growth of E. coli O157:H7 in packed pork. This study sheds light on the potential of Ag@Cu-MOF as a promising antimicrobial material for preserving pork.

江户时代,德川幕府通过与中国的书籍贸易,进口并翻刻了很多明清时代的杜诗学著作,很多刊刻活动是当时儒学家与书肆共同参与的结果。日本翻刻的主要是明代的杜律注本,尤以邵傅的《杜律集解》最多,江户时代学者还以《杜律集解》为基础,撰著了四部日本本土的杜诗注本。旧题李攀龙的《唐诗选》在江户时代流行一时,也产生大量注本,其中就包括对杜诗的注解。《唐诗选》系列注本对《饮中八仙歌》的阐释较有学术和文学批评价值。日本汉文学文集中有大量关于杜甫及杜诗的评论性资料,涉及对杜甫的总体评价以及对杜诗诗体和具体作品的评论。江户时代文人还留下了不少集杜诗,这以久贝蓼湾的《集杜五言诗》最具代表性。江户时代汉文学中也有不少拟效杜诗的作品,其中日本文人拟效的《饮中八仙歌》相关汉诗较有特色。

Participants received 1×1010CFU of L. reuteri CCFM1132.（n=34） or placebo （n=31） daily for 8 weeks. After the intervention， serum UA concentration significantly decreased， along with a reduction in xanthine oxidase （XOD） activity compared to the placebo group （P 2.relieves hyperuricemia by enhancing the abundance of SCFA producers in the gut to promote SCFA production and by suppressing XOD activity. This study provides a valuable reference for developing new treatments for hyperuricemia.

基于颠覆性创新技术的人工智能具有独特的科研驱动逻辑:通过催化驱动提升科学研究效率,通过协同驱动促进多维融合交互,通过算法驱动打破研究路径依赖。三重驱动逻辑的本质是某种形式化、程序化赋能,科学能否取得实质创新,关键在于科研人员、人工智能的创新潜质及两者的耦合交互水平。人工智能赋予科学研究新前景的同时,亦内隐多重潜在风险,如科研行动“道德失范”、研究过程“机械隐蔽”、形式创新“模糊真伪”、学术责任“无人承担”等。为降低驱动风险与提升驱动韧性,需要规制人工智能系统开发与应用,引导科研人员开展负责任创新,推进科学家与人工智能深度协同交互。
