当代社会认知的理论版图可分为经典概念工具箱与正在与之对抗的新概念工具两部分。经考证,理论论和模拟论等经典概念工具集中诞生于1980年代的美国认知科学界,可以被视为1956认知革命蔓延至社会心理学领域的产物,而新概念工具可以被视为与第二代认知革命相适合的替代理论。历史上,社会心理学接受了认知主义的“物”的抽象认知原理,也全盘接受了它带来的理论负荷,即对“人”的感知被还原为对“物”的感知,并且隶属于后者。然而,基于“物”的抽象认知原理始终无法与社会认知的以“人”为本的实践经验相结合,也未能实现该领域的自治。事实上,这一理论困难并非一直存在于“社会认知”的历史路径中,至少在以Heider为标志性人物的1950年代早期社会认知中便不是这样。Heider“人不是物”理论体系在个体层面上包括知觉实在论、事件归因和生命性−非生命性范畴区分三个部分,但是第三个理论部件彼时囿于作者主题侧重、证据不足、技术匮乏等多种原因未能完成。结合当代来自演化和比较的、行为和发展的以及神经通路假设的新证据,通过重新发掘并最终完整构建了“人不是物”论题,尝试为当代社会认知理论困难提供一个建设性意见。

Rational design of lipid-activatable NIR-II probes for precisely imaging atherosclerotic plaque

Science China Chemistry 2025年

作者： Xinyu Xu Yuan Ma Hui Cao Li Xu Haoming chen Sulai Liu wei Sun Guosheng Song Xiaobing Zhang State Key Laboratory for Chemo/Bio-Sensing and Chemometrics College of Chemistry and Chemical EngineeringHunan University Department of Hepatobiliary Surgery/Central Laboratory Hunan Provincial People's Hospital (The First Affiliated Hospital of Hunan Normal University) Department of Cardiology the First Affiliated Hospital of Nanjing Medical University Key Laboratory of Targeted Intervention of Cardiovascular Disease Collaborative Innovation Center for Cardiovascular Disease Translational MedicineNanjing Medical University Shenzhen Research Institute of Hunan University

Atherosclerosis(AS) is a prevalent condition associated with cardiovascular and cerebrovascular diseases, featuring lipid-laden plaque; however, the insufficient resolution and low sensitivity of traditional medical imaging techniques limit their application in lipid imaging. Currently, the second near-infrared(NIR-II) fluorescence imaging offers promising sensitivity and convenience. However, existing probes have limitations in terms of signal-to-background ratio, penetration depth, and tissue scattering. Herein, we use a molecular regulatory strategy to design a lipid-activatable probe Rh-965 with high specificity and NIR-II emission for improved imaging potential in deep tissues. The potential of Rh-965 for imaging plaque lipids in mice with AS is demonstrated by localizing carotid artery plaques using NIR-II imaging. The development of more stable lipid-activated NIR-II probes can significantly enhance atherosclerosis diagnosis and facilitate in vivo imaging in deeper tissues.

Gambogic acid induces cell apoptosis through endoplasmic reticulum stress triggered inhibition of Akt signaling pathways in extranodal NK/T-cell lymphoma cells

引用

Chinese Journal of Natural Medicines 2018年第9期16卷 693-699页

作者： PENG wei chen bao-An Department of Medical Oncology Jiangsu Cancer HospitalJiangsu Institute of Cancer ResearchNanjing Medical University Affiliated Cancer Hospital Department of Hematology and Oncology (Key Department of Jiangsu Medicine) Medical Schoolthe Affiliated Zhongda HospitalSoutheast University

As the chemotherapeutic resistance of extranodal NK/T-cell lymphoma(ENKTL) rises year by year, searching for novel chemoprevention compounds has become imminent. Gambogic acid(GA) has recently been shown to have anti-tumor effects, but its role and underling mechanism in ENKTL are rather elusive. In the present study, we showed that GA inhibited the cell growth and potently induced the apoptosis of ENKTL cells in vitro in a time-and concentration-dependent manner. Furthermore, GA induced cell death through endoplasmic reticulum stress(ERS) mediated suppression of Akt signaling pathways and finally the release of the caspase-3 proteases. Overall, our data provided evidences supporting GA as a potential therapeutic agent for ENKTL, which may facilitate further preclinical development of anti-tumor drugs.

Toward understanding the role of genomic repeat elements in neurodegenerative diseases

Neural Regeneration Research 2025年第3期20卷 646-659页

作者： Zhengyu An Aidi Jiang Jingqi chen Institute of Science and Technology for Brain-Inspired Intelligence Fudan UniversityShanghaiChina MOE Frontiers Center for Brain Science Fudan UniversityShanghaiChina MOE Key Laboratory of Computational Neuroscience and Brain-Inspired Intelligence Fudan UniversityShanghaiChina Zhangjiang Fudan International Innovation Center ShanghaiChina

Neurodegenerative diseases cause great medical and economic burdens for both patients and society;however, the complex molecular mechanisms thereof are not yet well understood. With the development of high-coverage sequencing technology, researchers have started to notice that genomic repeat regions, previously neglected in search of disease culprits, are active contributors to multiple neurodegenerative diseases. In this review, we describe the association between repeat element variants and multiple degenerative diseases through genome-wide association studies and targeted sequencing. We discuss the identification of disease-relevant repeat element variants, further powered by the advancement of long-read sequencing technologies and their related tools, and summarize recent findings in the molecular mechanisms of repeat element variants in brain degeneration, such as those causing transcriptional silencing or RNA-mediated gain of toxic function. Furthermore, we describe how in silico predictions using innovative computational models, such as deep learning language models, could enhance and accelerate our understanding of the functional impact of repeat element variants. Finally, we discuss future directions to advance current findings for a better understanding of neurodegenerative diseases and the clinical applications of genomic repeat elements.
