| 目的旨在系统梳理炎症性肠病( inflammatory bowel disease，IBD)与坏疽性脓皮病( pyoderma gangrenosum，PG)共病领域的研究演进趋势，并从亚型特异性角度深入揭示其分子交叉机制，以期为“肠 -皮”轴互作机制提供新的理论依据，并为不同 IBD亚型合并 PG的精准防治提供分子分型基础。方法整合文献计量学与生物信息学方法，检索 2000年 1月 1日至 2025年 8月 31日 Web of Science核心合集相关文献，利用 CiteSpace、VOSviewer等工具分析国家、机构、作者及关键词:的合作网络与主题演进。进一步通过 GeneCards与 STRING数据库筛选 IBD与 PG的共享基因，构建蛋白质互作网络，并进行基因本体 /京都基因和基因组数据库通路富集分析，重点比较克罗恩病( Crohn disease，CD)与溃疡性结肠炎( ulcerative colitis，UC)相关 PG在分子机制上的异同。结果文献计量分析显示该领域研究持续增长，欧美国家主导国际合作网络，中国虽发文量居前但国际合作与影响力较弱。生物信息学分析识别出 236个 IBD-PG共享基因，核心通路集中于“细胞因子 -细胞因子受体相互作用”等炎症免疫相关过程。关键创新点在于发现 CD背景下的 PG显著富集于白细胞介素 -17信号通路与志贺菌感染，而 UC相关 PG则突出富集于自然杀伤细胞介导的细胞毒性及耶尔森菌感染通路，揭示了两者在免疫启动机制上的亚型特异性差异。结论首次从多维度揭示 IBD与 PG共病具有“共性炎症基础、亚型特异通路”的双重特征，共病机制核心为“感染触发 -固有免疫激活 -细胞因子失衡 -免疫细胞浸润”通路，而 CD-PG与 UC-PG在关键信号通路上存在明显差异。该发现不仅深化了对“肠 -皮”轴互作机制的理解，也为基于 IBD亚型的 PG精准预防与靶向治疗提供了重要分子依据。 |

| Objective To systematically examine research trends in the comorbidity of inflammatory bowel disease (IBD) and pyoder-ma gangrenosum (PG) and to deeply elucidate their molecular cross-talk mechanisms from a subtype-specific perspective, thereby pro-viding new theoretical insights into the "gut-skin axis" and a molecular basis for the precise management of PG in different IBD sub-types.Methods Integrating bibliometric and bioinformatic approaches, relevant publications from January 1, 2000 to August 31, 2025were retrieved from the Web of Science Core Collection. Tools including CiteSpace and VOSviewer were employed to analyze collabora-tive networks and thematic evolution among countries, institutions, authors, and keywords. Shared genes between IBD and PG wereidentified using GeneCards and STRING databases, followed by construction of protein-protein interaction networks and gene ontology(GO)/Kyoto encyclopedia of genes and genomes (KEGG) enrichment analyses, with a focused comparison of molecular mechanisms be-tween Crohn disease (CD)-associated PG and ulcerative colitis (UC)-associated PG.Results Bibliometric analysis indicated sustainedgrowth in this field, with European and American countries leading international collaborations. Although China ranked among the toppublishing countries, its international collaboration and academic influence remained limited. Bioinformatic analysis identified 236shared genes between IBD and PG, with core pathways significantly enriched in inflammation-and immune-related processes such as "cytokine-cytokine receptor interaction." Notably, the key novel finding revealed that PG in the context of CD was significantly associat-ed with the IL-17 signaling pathway and Shigella infection, whereas UC-related PG was prominently enriched in natural killer cell-me-diated cytotoxicity and Yersinia infection pathways, highlighting subtype-specific differences in immune activation mechanisms be-tween the two conditions.Conclusions This study multi-dimensionally reveals the dual characteristics of IBD-PG comorbidity: com-mon inflammatory foundations coupled with subtype-specific pathways. The core mechanism involves an "infection trigger-innate im-mune activation-cytokine dysregulation-immune cell infiltration" axis, while CD-PG and UC-PG exhibit significant differences in key signaling pathways. These findings not only deepen the understanding of the "gut-skin axis" interaction but also provide a crucial mo-lecular basis for the precise prevention and targeted therapy of PG according to IBD subtypes. |
