Objective To examine the expression pattern of apoptosis signal-regulating kinase 1(ASK1)in the intestinal tissues of patients with Crohn's disease(CD),and analyze its mechanistic impact on intestinal epithelial barrier function and inflammatory responses.Methods Ileal tissue samples from Crohn's disease patients and healthy controls were collected.ASK1 protein level was assessed by immunohistochemistry,and its relationship with the Crohn's disease activity index(CDAI)was analyzed.A mouse model of acute colitis was constructed using TNBS,and subjected to qRT-PCR,Western blotting and immunohistochemistry for ASK1 expression,and the association between ASK1 expression and the disease activity index was examined.Lentivirus transfection was employed to create stable Caco-2 cell lines with altered ASK1 expression,and the intestinal barrier integrity and inflammation were assessed by measuring transepithelial electrical resistance(TEER),FITC-dextran leakage,and IL-6,IL-1β levels.Furthermore,the effects of ASK1 expression on Krüppel-like factor 4(KLF4)levels was examined using qRT-PCR and Western blotting.Results ASK1 was highly expressed in the ileum of CD patients and positively correlated with CDAI.In a TNBS-induced mouse model of acute colitis,ASK1 expression was up-regulated and positively correlated with DAI.Inflammation-induced ASK1 overexpression weakened the Caco-2 cell intestinal barrier,whereas ASK1 knockdown strengthened it.Moreover,ASK1 had the capability to enhance the expression of inflammatory factors.Additionally,ASK1 knockdown increased KLF4 expression,while overexpression decreased it,indicating a negative correlation between ASK1 and KLF4.Conclusion ASK1 expression is notably higher in CD and positively correlates with disease activity.ASK1 can influence intestinal barrier integrity and inflammatory factor expression,possibly through its impact on KLF4 expression.

Inflammatory bowel disease(IBD)is a chronic inflammatory disease of the gastrointestinal tract that includes Crohn's disease and ulcerative colitis.IBD may be caused by complex interactions between genetic susceptibility,environmental factors,and alterations in the gut microbiota,resulting in dysregulated innate and adaptive immune responses.Recent studies have identified macrophages in the intestinal inflammatory response as having the plasticity to not only regulate inflammation,but also to promote tissue repair and healing.As aberrant macrophage polarization occurs during the development of IBD,the balance between the phenotype and function of pro-inflammatory M1 and anti-inflammatory M2 macrophages is regulated by extracellular and intracellular stimuli,and this process is therefore expected to be a potential target for new therapeutic approaches.This article reviewed the progress of research on macrophage polarization in IBD.

OBJECTIVE To evaluate the quality of guidelines/consensus on therapeutic drug monitoring （TDM） of anti-tumor necrosis factor-α （TNF-α） in patients with inflammatory bowel disease （IBD） in China and globally. METHODS PubMed， Embase， CNKI， Wanfang data， VIP， and release websites of guidelines/consensus in China and globally were searched to collect guidelines/expert consensus on TDM with anti-TNF-α for IBD patients. The search period was from database establishment to June 2023. After two investigators independently screened the literature and extracted the data， the methodological quality of the included guidelines/consensuses was evaluated using the Appraisal of Guidelines for Research and Evaluation Ⅱ. The main recommendations of the included guidelines/consensuses were summarized. RESULTS A total of 9 articles were included， 3 were guidelines and 6 were expert consensus. The standardized percentages of the 9 guidelines/consensus in the 6 dimensions （scope and aims， participants， rigor of formulation， clarity of expression， application， and editorial independence） were 90.43%， 41.98%， 52.55%， 85.49%， 19.00%， and 76.85%， respectively. Eight guidelines/consensus had a recommendation of grade B and one consensus of grade C. The main recommendations involve TDM application scenarios， threshold ranges， strategy adjustments， detection methods， and interpretation of results. Most guidelines/consensus recommend passive TDM for non-responders. It is recommended to set the TDM concentration range according to the expected treatment results and make strategy adjustments in combination with the disease condition and TDM results. Additionally， the same test method is recommended for the same patient. Some guidelines/consensus hold that no differences were noted in the interpretation of results between biosimilar and original drug. CONCLUSIONS The overall quality of the included guidelines/consensus was fair， with relatively consistent recommendation. Clinicians need to understand the characteristics and limitations of TDM with this class of drugs， and interpret and apply results of TDM in combination with specific clinical treatment goals.

The teaching of radiology in standardized residency training needs a large number of case data to strengthen the subjective understanding and awareness of residents. The database built by residency training bases can meet the needs of teaching to a certain extent, but the conditions of training bases vary across regions, which makes it difficult to achieve homogeneity in the teaching of radiology. This article discusses the application of Eurorad database in the teaching of radiology in standardized residency training. This database is free of charge, reliable, and comprehensive and provides a large number of free reliable cases and images for teaching, covering both common and rare diseases. Moreover, it can also be used to cultivate the English ability and comprehensive quality of residents and help to establish a hierarchical training system for radiology and non-radiology residents, thereby promoting the improvement in the quality of standardized residency training. This article shows the potential value of Eurorad database in the teaching of radiology in standardized residency training, and comparative studies are needed in the future to further prove its effectiveness.

Mutations in the SAMD9 and SAMD9L genes are associated with MIRAGE syndrome and ATXPC syndrome, respectively. This study reports the clinical characteristics and genetic analysis of one case with SAMD9 mutation (c.3809T > A, p.F1270Y) and two cases with SAMD9L mutations (c.2675T > G, p.M892R; c.1096T > G, p.F366V and c.4517T > C, p.L1506p), none of which have been previously reported. All patients presented with recurrent infections, growth retardation, and myelodys-plasia, with varying degrees of involvement of multiple systems, including respiratory, gastrointestinal, immune, endocrine, neurological, and reproductive systems. In terms of treatment, two patients underwent regular intravenous immunoglobulin and their clinical symptoms improved, while one patient had a favorable recovery following hematopoietic stem cell transplantation at the age of 1 year and 5 months of age. SAMD9/SAMD9L gene mutations, therefore, chould be considered in children with recurrent infections, myelodysplasia, pancytopenia, and growth retardation. Early genetic testing is crucial for timely diagnosis and treatment, which may improve patient outcomes.
