通过对2019-2022年间涉及法条竞合的236份刑事裁判文书的案件事实、判决结果等基础信息进行数字化处理与样本分析,力求从司法实践的维度揭示法条竞合理论的微观运行样态,从而发现其在审判实践中面临的“真问题”。研究发现,司法人员对法条竞合存在范围的认识差异、对其与想象竞合的区分标准未能达成一致、对其类型划分也未形成有效共识、对普通法(条)与特别法(条)之间的适用关系认识不统一以及在裁判文书中适用的依据与解释不足等问题。这些问题的存在使得法条竞合理论在司法适用中难以有效发挥释法析理、定分止争的作用,不利于实现个案公平与司法裁判的统一。因此,应构建双层次处断模型,以期为司法实务构建一套流程清晰、规则简约、操作简便的程序规范。

Swelling and erosion assisted sustained release of tea polyphenol from antibacterial ultrahigh molecular weight polyethylene for joint replacement

Chinese Chemical letters 2025年第2期36卷 344-348页

The considerable hazard posed by periprosthetic joint infections underlines the urgent need for the rapid advancement of in-situ drug delivery systems within joint materials. However, the pursuit of sustained antibacterial efficacy remains a formidable challenge. In this context, we proposed a novel strategy that leverages swelling and erosion mechanisms to facilitate drug release of drug-loaded ultrahigh molecular weight polyethylene(UHMWPE), thereby ensuring its long-lasting antibacterial *** oxide(PEO), a hydrophilic polymer with fast hydrating ability and high swelling capacity, was incorporated in UHMWPE alongside the antibacterial tea polyphenol(epigallocatechin gallate,EGCG as representative). The swelling of PEO enhanced water infiltration into the matrix, while the erosion of PEO balanced the release of the encapsulated EGCG, resulting in a steady release. The behavior was supported by the EGCG release profiles and the corresponding fitted release kinetic *** demonstrated by segmented antibacterial assessments, the antibacterial efficiency was enhanced 2to 3 times in the PEO/EGCG/UHMWPE composite compared to that of EGCG/UHMWPE. Additionally, the PEO/EGCG/UHMWPE composite exhibited favorable biocompatibility and mechanical performance, making it a potential candidate for the development of drug-releasing joint implants to combat prosthetic bacterial infections.

Characteristics and Health Risks of Metal Elements in House Dust in Baotou

引用

Huanjing Kexue/Environmental Science 2025年第3期46卷 1362-1370页

作者： Wang, jing-Wen Zhou, Hai-jun lü, Yang-Chao Sun, Bing fu, Xiao-Tao Chun, Xi Wan, Zhi-Qiang Key laboratory of Mongolian Plateau's Climate System Universities of Inner Mongolia Autonomous Region College of Geographical Sciences Inner Mongolia Normal University Hohhot010022 China Hohhot Branch Station of Inner Mongolia Environmental Monitoring Center Hohhot010030 China

To understand the potential impact of metal elements in house dust in heavy industrial cities on human health，house dust samples were collected from 46 residential quarters of four urban districts of Baotou city. The contents of 13 metal elements were determined，and the pollution characteristics，sources，and health risks of metal elements were analyzed. The results showed that the enrichment factors and geo-accumulation indices of anthropogenic metals（Pb，As，Cu，Fe，Cd，Cr，Ni，and Zn）were extremely high，indicating a high pollution degree. The concentrations，enrichment factors，and geo-accumulation indices of iron smelting-related elements（Fe，Mn，Cr，and V）were in the order of Kundulun district > Qingshan district > jiuyuan district > Donghe district，which was negatively correlated with the distance from the large iron smelting enterprise. Principal component analysis identified five sources：the iron and steel smelting source，natural source，nonferrous metal smelting source，traffic source，and coal combustion，among which iron and steel smelting and natural sources were the major sources of metal elements in house dust in Baotou. The results of health risk assessment suggested that ingestion and dermal contact were the major exposure pathways of metal elements in house dust in Baotou. The influence of the inhalation pathway could be ignored. All individual metal elements had no carcinogenic risk to adults or children. However，the combined action of all elements posed a certain non-carcinogenic risk to children. Ni，As，and Cr had carcinogenic health risks to both adults and children. © 2025 Science Press.

内生性治理以乡村资源激活和村民参与为前提,以超地方力量和资源为补充,旨在实现内外主体联动促进内外资源转换成乡村内生治理动能,弥合“他治”和“自治”两种并行治理逻辑的裂缝,提升乡村治理效能。通过S村“镇村社联动”创新实践发现:内外主体通过识别、聚合与转换过程整合乡村内外资源,为乡村治理创造条件;通过乡村主体确权、用权和增权过程促进村民参与;通过多元主体耦合、动员与联动过程建构跨界合作网络;通过强化地方依赖、归属与认同再生产乡村集体价值。经由“资源整合、参与赋权、跨界合作和地方认同”的协同闭环实践激活了乡村内生治理动能,推动乡村治理有效。乡村内外主体通过打造上下联动、内外共生的协同-互补整合机制、外催-内推赋能机制、动态-弹性互动机制以及上下-内外联动机制实现内生性治理,重塑了乡村治理结构,提升了乡村社会应对不确定风险的能力。

THE development of agriculture faces significant challenges due to population growth, climate change, land depletion, and environmental pollution, threatening global food security [1]. This necessitates the development of sustainable agriculture, where a fundamental step is crop breeding to improve agronomic or economic traits, e.g., increasing yields of crops while decreasing resource usage and minimizing pollution to the environment [2].
