Guan Cha Zhe Wang· 2025-11-20 01:09
【文/观察者网 齐倩】 香港英文媒体《南华早报》11月19日刊文称,瑞士《前沿》杂志首席执行官弗雷德·芬特尔认为,中国 在科研产出和某些前沿领域正超越美国,硅谷和美国顶尖大学在塑造科学未来方面的主导地位可能正在 终结。《前沿》杂志是全球领先学术出版商之一。 芬特近期在一次采访中表示:"根据全球最大互联研究数据库Digital Science的数据,2024年中国研究人 员发表了110万篇论文,美国为88万篇,中美科研产出差距正在扩大。" 他提到,尽管美国传统上被视为医学研究领导者,但近期的出版趋势显示不同景象。 数据显示,2023年,中国在医学领域论文占比达40%,2024年进一步升至略超50%。在能源研究领域, 中国已是全球领导者,占该领域论文约35%,且影响力显著。 "毫无疑问,中国现在是科学出版和产出的领导者,"芬特称,"专利等其他指标进一步表明,中国不仅 在数量上,还在高质量科研产出上超越了美国。" 芬特提到,中国的科学崛起正成为其他国家的榜样,尤其是越南。他说:"我们最近会见了越南代表 团,他们有雄心勃勃的计划,要大幅增加研发投资,希望复制中国过去15到20年所获得的成果。" 弗雷德·芬特尔近期接受 ...
研究:美国家卫生研究院今年逾380项临床试验被迫中止
Xin Hua She· 2025-11-19 09:36
Core Insights - The Trump administration's significant reduction in federal research funding has led to the cancellation of over 380 clinical trials funded by the National Institutes of Health (NIH) from February to August this year, affecting more than 74,000 participants [1][2] - The halted clinical trials primarily focused on infectious disease research, prevention, behavioral interventions, as well as studies related to cancer, cardiovascular diseases, and mental health [1] - The abrupt funding cuts raise concerns about resource wastage, declining data quality, and the inability of researchers to fulfill their ethical responsibilities to participants [1] Research Impact - The study published in the Journal of the American Medical Association highlights that the interruption of these clinical trials lacks scientific justification and violates fundamental ethical principles of human subject research [1] - The implications of these funding cuts extend beyond the immediate trials, potentially causing long-term damage to the entire public health research ecosystem in the United States [2] - Public health experts emphasize that basic medical research relies on long-term planning and sustained investment, indicating that the effects of reduced research funding could be profound and lasting [2]

能量通量揭开重症患者肥胖之谜
GLP1减重宝典· 2025-10-14 14:14
Core Insights - The article discusses the metabolic reprogramming that occurs during critical illness, emphasizing the role of inflammation and immune response in altering energy distribution and substrate utilization within the body [6][9][27]. Metabolic Regulation Principles - The priority of substrate utilization shifts during critical illness, with the body first consuming glucose and glycogen, followed by fats and proteins. This shift is crucial for supporting immune and inflammatory cell needs, leading to significant breakdown of muscle and fat tissues [10][13]. - The liver and kidneys enhance gluconeogenesis during critical illness, utilizing lactate, glycerol, and amino acids as substrates, which is vital for maintaining glucose levels [13]. Immune and Inflammatory Cell Metabolism - Immune cells, particularly M1 macrophages and activated T cells, primarily rely on aerobic glycolysis (Warburg effect) for rapid ATP production and biosynthetic precursors, supporting inflammatory responses despite lower energy efficiency [16][18]. - Metabolic intermediates can epigenetically regulate gene expression, influencing inflammation and immune responses [17]. Muscle and Fat Tissue Metabolic Remodeling - In critical illness, white adipose tissue may convert to brown adipose tissue, enhancing thermogenic capacity, while obesity paradox suggests that obese individuals may have better survival rates due to greater energy reserves and anti-inflammatory factors [20][22]. - Muscle protein breakdown is significantly increased due to enhanced ubiquitin-proteasome and autophagy mechanisms, leading to muscle wasting [22][26]. Conclusion - The body adapts through metabolic reprogramming during critical illness to enhance immune protection and survival, with a focus on the roles of immune cell metabolism and the breakdown of muscle and fat tissues. Future research should explore innovative interventions targeting metabolic pathways to improve clinical outcomes for critically ill patients [27].
澳研究:新生儿足跟血基因测序有助于疾病早发现
Xin Hua Wang· 2025-10-11 06:32
目前,澳大利亚新生儿足跟血筛查能覆盖32种疾病。研究发现,新生儿家长对基因组测序的接受程度较 高,99.5%的家长认为这样的检查应推广到所有新生儿中。 研究人员说,将基因组测序纳入新生儿筛查能扩大疾病筛查范围,包括那些易导致儿童患癌的隐患以及 目前的标准筛查技术无法检测到的心脏和神经系统疾病。 新华社墨尔本10月11日电(记者徐海静)澳大利亚默多克儿童研究所近日发布一项研究成果说,在新生 儿筛查中加入基因组测序有助于额外发现数百种疾病风险,便于更早的诊断和治疗。 这一研究由默多克儿童研究所与澳大利亚维多利亚州临床遗传学服务共同领衔,研究成果新近发表在英 国《自然·医学》杂志上。研究人员发现,如果在现行的澳大利亚新生儿足跟血筛查中纳入基因组测 序,就可以在14天内提供数百种可治疗疾病的筛查结果。 这项研究利用足跟血样本对维多利亚州1000名新生儿进行了基因组测序,检查了605种与早发、严重且 可治疗疾病相关的基因。结果发现,其中16名新生儿出现基因疾病的可能性更高,而常规筛查只发现了 1人。 研究人员同时提醒,新生儿基因测序还面临着操作和伦理上的风险,包括费用、公平性、数据存储安全 性以及孩子成年后的决策权等。 ...

Core Viewpoint - The article discusses the significance of the Nobel Prize in Physiology or Medicine awarded to Japanese scientist Shimon Sakaguchi for his research on regulatory T cells, which has revolutionized immunotherapy and deepened the understanding of the immune system [4][8]. Summary by Sections Discovery and Importance of Regulatory T Cells - Regulatory T cells play a crucial role in maintaining immune balance, and their subtle changes in quantity can significantly impact health. A decrease can lead to autoimmune diseases like type 1 diabetes and lupus, while an increase can result in tumors and infections [9][10]. - The discovery of regulatory T cells by Sakaguchi and his colleagues has advanced research in autoimmune diseases and the immune system's functioning [8]. Shimon Sakaguchi's Journey - Sakaguchi faced skepticism and was labeled an "heretic" in the scientific community for proposing the existence of regulatory T cells, which contradicted the prevailing view that T cells only had an attacking function [11][27]. - His research journey was marked by persistence despite numerous challenges, including funding issues and rejection from top journals [35][36]. Breakthroughs and Collaborations - The turning point in Sakaguchi's research came when he linked the Foxp3 gene mutation to regulatory T cells, confirming their role in autoimmune diseases [42]. - Collaborations with scientists like Mary Blenko and Fred Ramsdell were pivotal in validating his findings and advancing the research [49]. Future Implications - Although the discovery of regulatory T cells has not yet directly translated into clinical applications, it provides potential therapeutic targets for autoimmune diseases and cancer treatment [47]. - Sakaguchi emphasizes the importance of time and persistence in scientific research, highlighting that breakthroughs often require sustained effort and collaboration [49].
