Metabolic dysfunction-associated steatotic liver disease (MASLD) represents a major global health challenge characterized by complex adipose-liver interactions mediated by adipokines and hepatokines. Despite rapid field evolution, a comprehensive understanding of research trends and translational advances remains fragmented. This study systematically maps the scientific landscape through bibliometric analysis, identifying emerging domains and future clinical translation directions. A comprehensive bibliometric analysis of 1002 publications from 2004 to 2025 was performed using thematic mapping, temporal trend evaluation, and network analysis. Analysis included geographical and institutional distributions, thematic cluster identification, and research paradigm evolution assessment, focusing specifically on adipokine-hepatokine signaling mechanisms and clinical implications. The United States and China are at the forefront of research output, whereas European institutions significantly contribute to mechanistic discoveries. The thematic map analysis reveals the motor/basic themes residing at the heart of the field, such as insulin resistance, fatty liver, metabolic syndrome, steatosis, fetuin-A, and other related factors that drive innovation. Basic clusters include metabolic foundations (obesity, adipose tissue, FGF21) and adipokine-centered subjects (adiponectin, leptin, NASH). New themes focus on inflammation, oxidative stress, gut microbiota, lipid metabolism, and hepatic stellate cells. Niche areas show targeted fronts such as exercise therapies, pediatric/novel adipokines (chemerin, vaspin, omentin-1), and advanced molecular processes that focus on AMPK and endoplasmic-reticulum stress. Temporal analysis shows a shift from single liver studies to whole models that include the gut microbiota, mitochondrial dysfunction, and interactions between other metabolic systems. The network analysis identifies nine major clusters: cardiovascular-metabolic links, adipokine-inflammatory pathways, hepatokine control, and new therapeutic domains such as microbiome interventions and cellular stress responses. In summary, this study delineates current trends and emerging areas within the field and elucidates connections between mechanistic research and clinical translation to provide guidance for future research and development in this rapidly evolving area.
代谢功能障碍相关脂肪性肝病(MASLD)是一项重大的全球健康挑战,其特征是由脂肪因子和肝因子介导的复杂的脂肪-肝脏相互作用。尽管该领域发展迅速,但对研究趋势和转化进展的全面理解仍不完整。本研究通过文献计量分析系统地描绘了科学格局,确定了新兴领域和未来的临床转化方向。使用主题映射、时间趋势评估和网络分析对2004年至2025年的1002篇出版物进行了全面的文献计量分析。分析包括地理和机构分布、主题聚类识别以及研究范式演变评估,特别关注脂肪因子-肝因子信号传导机制和临床意义。美国和中国在研究产出方面处于领先地位,而欧洲机构对机制发现做出了重大贡献。主题映射分析揭示了该领域核心的驱动/基础主题,如胰岛素抵抗、脂肪肝、代谢综合征、脂肪变性、胎球蛋白-A以及其他推动创新的相关因素。基础聚类包括代谢基础(肥胖、脂肪组织、FGF21)和以脂肪因子为中心的主题(脂联素、瘦素、非酒精性脂肪性肝炎)。新主题聚焦于炎症、氧化应激、肠道微生物群、脂质代谢和肝星状细胞。细分领域展示了有针对性的前沿研究,如运动疗法、儿科/新型脂肪因子(chemerin、vaspin、网膜素-1)以及关注AMPK和内质网应激的先进分子过程。时间分析显示,研究从单一肝脏研究转向包括肠道微生物群、线粒体功能障碍以及其他代谢系统之间相互作用的整体模型。网络分析确定了九个主要聚类:心血管-代谢联系、脂肪因子-炎症途径、肝因子控制以及微生物群干预和细胞应激反应等新治疗领域。总之,本研究描绘了该领域当前的趋势和新兴领域,阐明了机制研究与临床转化之间的联系,为这一快速发展领域的未来研发提供指导。
