在2025年欧洲胃肠病学周（UEG Week 2025）活动上发布的一项最新研究表明，微塑料（环境中常 见的小于5毫米的塑料颗粒）会改变人类肠道微生物群，其中一些变化类似于与抑郁症和结直肠癌相关 的模式。这项研究是首批直接检查不同类型微塑料如何与人体肠道微生物群相互作用的研究之一。 这些细菌组成的变化伴随着细菌产生的化学物质的变化，其中一些与观察到的酸度增加相对应。某 些微塑料类型改变了戊酸和5-氨基戊酸的水平，而另一些则影响赖氨酸或乳酸，突出了微塑料—微生物 群相互作用的复杂性。 重要的是，在这些微塑料诱导的微生物组成变化中，有些反映了先前与抑郁症和结直肠癌等疾病相 关的模式，凸显了微塑料暴露对疾病风险的潜在影响。 虽然总细菌细胞数和活细菌细胞数基本保持不变，但与对照组相比，经微塑料处理的培养物的酸度 持续显著增加，表明微生物代谢活动发生了改变。 进一步分析显示，细菌组成发生了微塑料特异性的变化，某些细菌群体的数量增加或减少，具体取 决于微塑料的类型。在几个细菌科中观察到的变化，大多发生在芽孢杆菌门内。芽孢杆菌门是肠道细菌 的一个关键群体，对消化和整体肠道健康至关重要。 该研究使用5名健康志愿者的粪便样本进 ...

增加借款却不能带来业务利润的增长。近几年来，国恩股份收入虽有增长，但净利润徘徊不前，包括公 司实控人在内的一众高管，并没有因为国恩股份利润徘徊而放弃加薪。与此同时，公司员工的人均收入 却不增反降。 2025年6月底递交港股上市招股书后，9月初国恩股份（002768）收到证监会反馈意见，就公司股本变 化、实控人债务和控制权以及业务经营等问题提出问询。 国恩股份不只存在实控人偿债能力问题，近些年来，国恩股份的资产负债率一年高比一年，有息债务不 断增长。尤其是短期债务方面，公司短期债务的增长尤为明显，由之而来的利息费用不断膨胀。 利润徘徊短债攀升 国恩股份已经在A股上市，此次港股上市成功后，公司将成为实现"A+H"两地上市公司中新的一员。 国恩股份横跨化工和健康两大领域，化工是公司核心收入来源。公司以有机高分子材料改性业务为基 石，向上游延伸至苯乙烯、聚苯乙烯、可发性聚苯乙烯及聚丙烯等绿色石化材料业务。 公司援引弗若斯特沙利文资料，按2024年中国高分子材料改性相关板块营收计算，国恩股份是中国第二 大的有机高分子材料改性生产企业。按2024年中国聚苯乙烯相关产能计，公司是中国最大的聚苯乙烯生 产企业。 2022年， ...

Core Viewpoint - The study conducted by researchers at the University of Rhode Island indicates that microplastics and nanoplastics, which are prevalent in the environment, can accumulate in the brain and potentially lead to cognitive decline and symptoms similar to Alzheimer's disease, particularly in individuals carrying genetic risk factors like the APOE4 gene [1][5]. Group 1: Research Findings - Microplastics can penetrate various human body systems, including the brain, and may cross the blood-brain barrier, which typically protects the brain from harmful substances [1][2]. - The study involved genetically modified mice carrying the APOE4 gene, which is a significant risk factor for Alzheimer's disease, showing that these mice are approximately 3.5 times more likely to develop the disease compared to those with the APOE3 gene variant [1][2]. - The research demonstrated that exposure to microplastics led to behavioral changes in mice, such as increased exploration in open areas and impaired recognition of new objects, indicating cognitive decline [3][4]. Group 2: Implications and Future Research - The findings raise concerns about the widespread exposure to microplastics as environmental toxins and highlight the need for further research into their health impacts [5]. - The study encourages stricter regulations on microplastics, with the U.S. House of Representatives proposing the Microplastics Safety Act to investigate the effects of microplastics on human health, particularly in vulnerable populations [5]. - The researcher emphasizes the necessity for increased funding and research on the health impacts of microplastics, noting that observed trends in mice align with real-world observations [5].

Core Viewpoint - The collaboration among Asahi Kasei, Mitsui Chemicals, and Mitsubishi Chemical aims to establish a limited liability partnership, Setouchi Ethylene LLP, focusing on carbon reduction technologies and capacity optimization in ethylene production facilities in western Japan, with a goal of achieving a green transition by 2030 [2][5]. Group 1: Ethylene Production and Carbon Emissions - Ethylene is one of the largest chemical products globally, with its production process accounting for 1.8% of global industrial emissions, primarily due to high-temperature energy consumption in steam cracking furnaces [5]. - Japan, as the third-largest ethylene producer, has an annual capacity of approximately 10 million tons, but its carbon intensity is 20%-30% higher than that of Europe and the U.S. [5]. - The Japanese Ministry of Economy, Trade and Industry (METI) plans to achieve a 40% reduction in emissions from the chemical industry by 2030, making the stability, greening, and efficiency optimization of ethylene production crucial for the development of downstream engineering plastics [5]. Group 2: Strategies for Green Transition - The three companies have been discussing specific measures to promote carbon neutrality in ethylene production facilities since last year, focusing on transitioning raw materials from traditional petroleum resources to biomass-based materials and introducing low-carbon fuels [6]. - They plan to optimize production frameworks, including potential capacity reductions for more efficient resource utilization, and have agreed that forming the LLP is the best way to deepen cooperation and accelerate their goals [6]. - Asahi Kasei has developed a "lignin cracking technology" that can convert paper waste and other biomass into ethylene feedstock, which can replace some petroleum-based raw materials. Pilot data shows that with a biomass ratio of 20%, carbon emissions can be reduced by 35%, and costs are 15% lower than traditional bioethanol routes [6]. Group 3: Differences Between Bio-based Olefins and Traditional Ethylene - Bio-based ethylene opens a new pathway for ethylene production, sourced from renewable biomass resources such as agricultural and forestry waste, through a series of biological and chemical conversion processes [7]. - The carbon emissions from bio-based ethylene production are significantly lower, with CO2 emissions ranging from 0.8 to 1.2 kg CO2 per kg of product, representing a 60% reduction compared to petrochemical routes [7]. - However, challenges remain in terms of cost competitiveness, with raw material costs accounting for 60%-70% of total costs, and higher energy consumption compared to petrochemical processes [7]. Group 4: Industry Movements and Innovations - Major companies like Braskem, BASF, and New Energy Blue are pursuing bio-based ethylene as a key focus area in the context of low-carbon sustainability [7]. - Braskem, the sixth-largest petrochemical company globally, has been producing bio-based polyethylene since 2010 and is expanding its bio-based ethylene production capacity in Brazil [8]. - In China, Sinopec has made significant strides in bio-based polyethylene, successfully launching its first bio-based product in September 2024, with an initial production of 2,500 tons [10].
