Postoperative recurrence (POR) is a major challenge in the long-term management of Crohn's disease (CD), affecting up to 70% of patients within the first year after surgical resection. The multifactorial pathogenesis of POR complicates prevention, while evolving surgical techniques and different anastomotic configurations further hinder accurate prediction and monitoring.Current surveillance strategies, including standard ileocolonoscopy and faecal calprotectin, remain limited by suboptimal accuracy, the absence of validated scoring systems and the lack of standardised monitoring intervals. Recent advances in high-resolution endoscopic imaging, such as confocal laser endomicroscopy and endocytoscopy, enable real-time, in vivo microstructural assessment of the anastomosis, offering opportunities for earlier and more precise detection of recurrence. In parallel, developments in intestinal ultrasound and cross-sectional imaging are reshaping non-invasive monitoring by providing transmural evaluation. Beyond imaging, multiomics approaches, spanning genomics, transcriptomics, proteomics, metabolomics and metagenomics, are uncovering novel biological pathways linked to POR, providing new mechanistic insights.Artificial intelligence (AI) has the potential to integrate clinical, endoscopic, imaging and omics data into predictive multimodal models for POR, supporting individualised risk stratification, early detection and personalised treatment strategies. While promising, these innovations require prospective validation, methodological standardisation and integration into clinical workflows before translation into routine practice.This review summarises the current understanding of POR, highlights emerging diagnostic and monitoring technologies and explores how AI-enabled endoscopy and multi-omics approaches may transform future management, paving the way towards precision medicine for POR in CD.
术后复发(POR)是克罗恩病(CD)长期治疗的主要挑战,在手术切除后的一年内影响高达70%的患者。POR的多因素发病机制使预防复杂化,而不断发展的手术技术和不同的吻合口构型进一步阻碍了准确的预测和监测。目前的监测策略,包括标准回肠结肠镜检查和粪便钙保护蛋白,仍然受到准确性不理想、缺乏有效的评分系统和缺乏标准化监测间隔的限制。高分辨率内窥镜成像的最新进展,如共聚焦激光内窥镜和内吞镜,能够实时、在体内评估吻合口的显微结构,为更早、更精确地发现复发提供了机会。与此同时,肠道超声和横断面成像的发展正在通过提供跨壁评估重塑无创监测。除了成像,多组学方法,包括基因组学、转录组学、蛋白质组学、代谢组学和宏基因组学,正在发现与POR相关的新的生物学途径,提供新的机制见解。人工智能(AI)有潜力将临床、内窥镜、成像和组学数据整合到POR的预测多模态模型中,支持个性化风险分层、早期检测和个性化治疗策略。虽然这些创新很有希望,但在转化为常规实践之前,需要前瞻性验证、方法标准化和整合到临床工作流程中。本文总结了目前对POR的理解,重点介绍了新兴的诊断和监测技术,并探讨了人工智能内窥镜和多组学方法如何改变未来的管理,为CD中的POR的精准医学铺平了道路。

BACKGROUNDRNA 5-methylcytosine (m5C) has emerged as a critical epigenetic regulator in cancer biology, yet its role in the tumour immune microenvironment (TME) remains incompletely understood.OBJECTIVEWe aimed to elucidate the functional role and underlying mechanism of NOP2/Sun RNA methyltransferase 6 (NSUN6), an m5C methyltransferase, in shaping the TME of pancreatic ductal adenocarcinoma (PDAC).DESIGNThe clinical significance of NSUN6 was assessed in human PDAC cohorts. The impact of NSUN6 on antitumour immunity was evaluated using murine PDAC models. Single-cell RNA sequencing was employed to characterise the TME landscape of PDAC. RNA bisulfite sequencing and RNA sequencing were used to identify NSUN6 targets. The synergistic effects of C-C motif chemokine ligand 2 (CCL2) blockade combined with immune checkpoint blockade (ICB) therapy were investigated.RESULTSNSUN6 deficiency significantly enhanced macrophage accumulation and polarisation toward immunosuppressive phenotypes, thereby impairing CD8+ T cell-mediated antitumour immunity in PDAC. Mechanistically, NSUN6 deficiency downregulated KDM5A expression in an m5C-dependent manner, resulting in transcriptional activation of CCL2. Elevated CCL2 secretion promoted the accumulation and polarisation of protumorous macrophages, fostering an immunosuppressive TME and inducing resistance to ICB. Notably, CCL2 blockade reversed protumorous macrophage infiltration and restored ICB sensitivity in Nsun6-deficient murine PDAC models. Clinical analysis further revealed a positive correlation between NSUN6 expression and favourable immune responses in ICB-treated cohorts.CONCLUSIONNSUN6 deficiency drives immune suppression through the m5C-KDM5A-CCL2 axis in PDAC. Targeting the NSUN6-CCL2 axis represents a promising strategy to sensitise PDAC to ICB therapy.
drna 5-甲基胞嘧啶(m5C)已成为癌症生物学中重要的表观遗传调控因子,但其在肿瘤免疫微环境(TME)中的作用仍未完全了解。目的:研究NOP2/Sun RNA甲基转移酶6 (NSUN6)和m5C甲基转移酶在胰腺导管腺癌(PDAC) TME形成中的作用及其机制。设计在人类PDAC队列中评估NSUN6的临床意义。采用小鼠PDAC模型评估NSUN6对抗肿瘤免疫的影响。单细胞RNA测序用于表征PDAC的TME景观。采用亚硫酸氢盐RNA测序和RNA测序对NSUN6靶点进行鉴定。研究了C-C基序趋化因子配体2 (CCL2)阻断联合免疫检查点阻断(ICB)治疗的协同效应。结果tsnsun6缺陷显著增强了巨噬细胞的积累和极化,从而损害了PDAC中CD8+ T细胞介导的抗肿瘤免疫。机制上,NSUN6缺乏以m5c依赖的方式下调KDM5A的表达,导致CCL2的转录激活。升高的CCL2分泌促进了原肿瘤巨噬细胞的积累和极化,形成免疫抑制TME并诱导对ICB的抵抗。值得注意的是,在nsun6缺陷小鼠PDAC模型中,CCL2阻断逆转了原瘤巨噬细胞浸润并恢复了ICB敏感性。临床分析进一步显示,在接受icb治疗的队列中,NSUN6表达与良好的免疫反应呈正相关。结论nsun6缺乏通过m5C-KDM5A-CCL2轴驱动PDAC的免疫抑制。靶向NSUN6-CCL2轴是一种很有前途的策略,可以使PDAC对ICB治疗敏感。

BACKGROUNDCoexistence of metabolic dysfunction-associated steatotic liver disease (MASLD) increases hepatocellular carcinoma (HCC) risk after HCV cure.OBJECTIVEThe specific impacts of steatosis grade and cardiometabolic burden on HCC risk among patients with MASLD remain unclear.DESIGNWe enrolled 700 patients who underwent biannual HCC surveillance after HCV cure. Steatosis was graded by vibration-controlled transient elastography using controlled attenuation parameter cut-offs of 248-267, 268-279 and ≥280 dB/m, corresponding to S1, S2 and S3, respectively. Cardiometabolic risk factors (CMRFs) were assessed at the time of viral cure. Cumulative HCC incidence was compared across steatosis grades and cardiometabolic burdens using the log-rank test. Multivariable Cox proportional hazards models with Akaike Information Criterion-based selection evaluated the effects of steatosis grade, cardiometabolic burden and individual CMRFs on HCC risk, expressed as adjusted HRs (aHRs) with 95% CIs. Fine-Gray subdistribution hazard models were used for sensitivity analyses.RESULTSCumulative HCC incidence differed significantly across steatosis grades (p=0.035) but not across cardiometabolic burdens (p=0.62). In multivariable analysis adjusted for age, sex, liver stiffness and alpha-fetoprotein, advanced steatosis remained independently associated with HCC risk (S3 vs S1: aHR 2.15, 95% CI 1.25 to 3.69, p=0.005). Among individual CMRFs, pre-diabetes or type 2 diabetes was significantly associated with HCC risk (aHR 2.33, 95% CI 1.38 to 3.94, p=0.002). Fine-Gray analyses confirmed these associations.CONCLUSIONAdvanced hepatic steatosis and glycaemic abnormalities, rather than overall cardiometabolic burden, are independently associated with increased HCC risk after HCV cure.
背景:代谢功能障碍相关脂肪变性肝病(MASLD)的共存增加了HCV治愈后发生肝细胞癌(HCC)的风险。目的:脂肪变性等级和心脏代谢负担对MASLD患者HCC风险的具体影响尚不清楚。设计:我们招募了700名HCV治愈后接受半年HCC监测的患者。通过振动控制瞬态弹性学对脂肪变性进行分级,采用控制衰减参数截止值为248-267、268-279和≥280 dB/m,分别对应S1、S2和S3。在病毒治愈时评估心脏代谢危险因素(CMRFs)。使用log-rank检验比较不同脂肪变性等级和心脏代谢负荷的累积HCC发病率。基于赤道信息标准选择的多变量Cox比例风险模型评估了脂肪变性等级、心脏代谢负担和个体cmrf对HCC风险的影响,以校正hr (aHRs)表示,ci为95%。敏感性分析采用细灰色亚分布风险模型。结果肝细胞癌的累积发病率在脂肪变性分级中有显著差异(p=0.035),但在心脏代谢负荷组中无显著差异(p=0.62)。在调整了年龄、性别、肝脏硬度和甲胎蛋白的多变量分析中,晚期脂肪变性仍然与HCC风险独立相关(S3 vs S1: aHR 2.15, 95% CI 1.25 ~ 3.69, p=0.005)。在个体cmrf中,糖尿病前期或2型糖尿病与HCC风险显著相关(aHR 2.33, 95% CI 1.38至3.94,p=0.002)。精细灰色分析证实了这些关联。结论:晚期肝脂肪变性和血糖异常与HCV治愈后HCC风险增加独立相关,而非总体心脏代谢负担。

BACKGROUNDGenetic studies of stool frequency (SF), an indirect proxy for gastrointestinal transit, may reveal therapeutically tractable pathways relevant to IBS and other dysmotility disorders.OBJECTIVETo identify genes and mechanisms involved in gut motility, providing a foundation for clinical translation.DESIGNWe performed a multiancestry genome-wide association study (GWAS) meta-analysis of SF in 268 606 European and East Asian individuals. Heritability and genetic correlations with other traits were estimated, and Mendelian randomisation was used to test causal relationships. GWAS signals were fine-mapped and functionally annotated to prioritise candidate genes and pathways. Findings implicating thiamine metabolism were followed-up with dietary interaction analyses in UK Biobank (UKB).RESULTSSF heritability was comparable in Europeans (7.0%) and East Asians (5.6%). We observed strong genetic correlations with gastrointestinal and psychiatric disorders (rg=0.18-0.47), and causal effects on IBS. Novel correlations with cardiovascular traits (rg=0.12-0.14) were supported by drug signature enrichment analyses. We identified 21 independent loci, including 10 novel signals implicating bile acid synthesis (KLB) and cholinergic signalling (COLQ). Fine-mapping converged on vitamin B1 metabolism, highlighting single-variant causal effects at SLC35F3 (a thiamine transporter) and XPR1 (phosphate exporter essential for thiamine activation). In 98 449 UKB participants, thiamine intake was positively associated with SF (p<0.0001), and a combined SLC35F3/XPR1 genotype score significantly modulated this effect (p<0.0001).CONCLUSIONSWe identify therapeutically tractable mechanisms involved in the control of gut motility, including a previously unrecognised role for vitamin B1. These findings warrant mechanistic and clinical studies to evaluate their translational potential in IBS and other dysmotility syndromes.
粪便频率(SF)是胃肠道运输的间接指标,其遗传学研究可能揭示与肠易激综合征和其他运动障碍相关的治疗途径。目的确定肠道运动相关基因和机制,为临床翻译提供基础。我们对268606名欧洲和东亚个体的SF进行了多祖先全基因组关联研究(GWAS)荟萃分析。估计遗传率和与其他性状的遗传相关性,并使用孟德尔随机化来检验因果关系。对GWAS信号进行精细定位和功能注释,以优先考虑候选基因和途径。英国生物银行(UKB)对硫胺素代谢的研究结果进行了饮食相互作用分析。结果ssf遗传率在欧洲(7.0%)和东亚(5.6%)具有可比性。我们观察到与胃肠道和精神疾病有很强的遗传相关性(rg=0.18-0.47),以及对IBS的因果影响。药物特征富集分析支持了与心血管特征的新相关性(rg=0.12-0.14)。我们发现了21个独立的基因座,包括10个新的信号,涉及胆汁酸合成(KLB)和胆碱能信号(COLQ)。精细绘图集中在维生素B1代谢上,突出了SLC35F3(硫胺素转运蛋白)和XPR1(硫胺素激活所必需的磷酸盐出口蛋白)的单变异因果效应。在98449名UKB参与者中,硫胺素摄入量与SF呈正相关(p<0.0001), SLC35F3/XPR1基因型组合评分显著调节了这一效应(p<0.0001)。结论:我们确定了肠道运动控制的治疗机制,包括维生素B1以前未被认识到的作用。这些发现需要进行机制和临床研究,以评估其在肠易激综合征和其他运动障碍综合征中的转化潜力。

Heritability and genetic correlations with other traits were estimated, and Mendelian randomisation was used to test causal relationships. GWAS signals were fine-mapped and functionally annotated to prioritise candidate genes and pathways. Findings implicating thiamine metabolism were followed-up with dietary interaction analyses in UK Biobank (UKB).RESULTSSF heritability was comparable in Europeans (7.0%) and East Asians (5.6%). We observed strong genetic correlations with gastrointestinal and psychiatric disorders (rg=0.18-0.47), and causal effects on IBS. Novel correlations with cardiovascular traits (rg=0.12-0.14) were supported by drug signature enrichment analyses. We identified 21 independent loci, including 10 novel signals implicating bile acid synthesis (KLB) and cholinergic signalling (COLQ). Fine-mapping converged on vitamin B1 metabolism, highlighting single-variant causal effects at SLC35F3 (a thiamine transporter) and XPR1 (phosphate exporter essential for thiamine activation).
