The escalating utilization of nuclear energy and nuclear medicine raises concerns about the environmental impact of radioactive iodine, necessitating the development of effective iodine adsorbents, especially under a real-world scenario with extremely low iodine concentration and elevated temperature. Herein, we have presented the construction of a nitrogen-abundant two-dimensional（2D） halogen-bonded organic framework, XOF-TNP, characterized by exceptional crystallinity, thermal stability, and nitrogen-rich structures. XOF-TNP exhibits strong binding to iodine, thanks to the fact that iodine can be pre-enriched into the framework through N···I interactions. The nitrogen-rich framework and I+synergistically have extremely high binding force to iodine, enabling the rapid and efficient capture of iodine in both vapor and solution phases, with significant recyclability. Further flow-through adsorption experiments using an XOF-TNP-packed column achieve 99% iodine removal from hexane and aqueous solutions, surpassing traditional activated carbon. This highlights its potential for environmental remediation. XOFTNP enables the development of a novel rewritable security paper, utilizing its iodine adsorption properties to encrypt and decrypt QR codes. This research expands the application scope of halogen-bonded organic frameworks, providing insights into the design of materials for environmental remediation and security applications.

Gestational diabetes mellitus (GDM) is a disease of glucose intolerance that first occurs during pregnancy. Accumulating evidence underlined a link between gut microbiota dysbiosis and GDM， and microbial metabolites represent a unique way to explore microbiota–host interactions. However， the associations between changes in the gut microbiota and microbial metabolites and immune homeostasis in the GDM pathogenesis remain largely unclear. In this prospective study， the characteristics of gut microbiota in both first trimester (T1) and second trimester (T2 ) were investigated in 46 GDM patients and 44 matched controls. We comprehensively profiled the microbial metabolites using non-targeted metabolomics and quantitatively targeted metabolomics， measurements of inflammatory cytokines and biomarkers of intestinal barrier function， and combined with correlation analysis in T2. Gut microbiota dybiosis was observed in GDM patients in both T1 and T2， and was characterised by the enrichment of multiple potentially harmful bacteria， such as UBA1819 and Erysipelatoclostridium. Besides， alterations in the microbiota were accompanied by a disturbance in tryptophan metabolism， mainly manifested as a shift towards the production of more kynurenine and less indole derivatives. Most importantly， correlation network analysis indicated that overgrowth of potential pathogens and tryptophan metabolism disorder were associated with inflammatory imbalance and disrupted epithelial barrier in GDM patients. Theses findings provide a greater understanding of the pathogenesis and new targets for microecological interventions by mediating tryptophan metabolism in GDM.

生活圈的边界划定是社区生活圈研究的重点也是难点。现有的划定方法有基于行政边界或控规单元、依据设施服务半径及可达性、居民日常活动行为三种方式,其中基于居民日常活动是最接近社区生活圈本意的测度方法。但目前这一方法的应用主要依靠全球定位系统(GPS)数据,成本高且样本有限,难以描述社区大多数居民的活动规律,更缺乏对大范围不同类型社区生活圈的全貌认识。以成都市为例,基于大样本的手机位置服务数据(LBS),采用复杂网络分析技术(Infomap)对中心城区(549 km^(2))的社区生活圈进行测度,通过识别其规模和边界特征,进一步探讨空间要素对社区生活圈边界的影响及作用机制。结果表明:通过选取恰当的单元精度和距离约束d值,可以获得较好的网络聚类结果(接近15 min生活圈的实际规模);基于LBS数据划分的社区生活圈面积规模差异较大,但大多数的规模处于1~5 km^(2)之间;三类代表性空间要素中,路网密度与社区生活圈面积规模存在中等程度相关,区位和商业兴趣点(POI)密度与社区生活圈规模并不存在显著的相关性;但社区生活圈的人口密度与三类空间要素存在强相关。基于手机LBS数据的社区生活圈测度方法可以加深对社区生活圈现象的理解,并为社区生活圈规划提供理论与技术支撑。
