Summary: Chronic colonic inflammation can lead to dysplasia and cancer. Activation of TLR4 is associated with up-regulation of DUOX2 and NOX1, leading to increased epithelial production of H2O2, promoting colorectal tumor formation.

Summary: It has been found that high levels of Systemic immune-inflammation index (SII) are associated with poor outcomes in ulcerative colitis (UC) patients. Our study confirmed that SII levels were significantly elevated in UC patients and closely correlated with disease activity, showing high diagnostic capacity for active UC.

Summary: The study found that the esterified alginate-curcumin conjugate exhibited effective anti-inflammatory effects in Raw 264.7 cells, and after oral administration in animals, the majority reached the colon rapidly and released curcumin, effectively reducing colonic inflammation and tissue damage. The curcumin release triggered by commensal flora shows great potential for ulcerative colitis treatment.

Summary: The therapeutic effect and molecular mechanisms of Piper wallichii extract on DSS-induced ulcerative colitis in mice were investigated. The extract improved the symptoms of ulcerative colitis mice by enhancing intestinal barrier function, regulating inflammatory factors, and modulating the immune system. The TLR4/NF-Kappa B/COX-2 signaling pathway was found to be involved in the anti-inflammatory effect of Piper wallichii extract.

Summary: Ulcerative colitis (UC) is specifically affected by genetic alterations, environmental factors, microbiota, and mucosal immune dysregulation, leading to a lack of response in 30%-55% of patients to current therapies. The expression levels of cytokines associated with treatment depend on disease stage and patient characteristics, suggesting that future targeted therapies should focus on these differences and individual cytokine profiles.

Summary: Salidroside, a glycoside extracted from Rhodiola rosea L., was found to ameliorate dextran sulfate sodium (DSS)-induced colitis by modulating the gut microbiota. Salidroside treatment inhibited colitis symptoms in mice, including colon length, histology, disease activity index (DAI) score, and macrophage levels in the intestine. In a fecal microbiota transplantation (FMT) study, fecal samples from Salidroside-treated mice significantly alleviated colitis symptoms in recipient mice, indicating the importance of gut microbiota in the therapeutic effect. Salidroside and FMT both influenced the structure and abundance of the gut microbiota, with decreased relative abundance of Turicibacter, Alistipes, Romboutsia, and increased relative abundance of Lactobacillus. The anti-inflammatory effect of Salidroside was dependent on the presence of gut microbiota, as evidenced by its disappearance in antibiotic-treated mice. Salidroside could be a promising functional food for colitis treatment.

Summary: This study investigates the anti-inflammatory effects of peiminine on ulcerative colitis. The results demonstrate that peiminine treatment can alleviate inflammatory manifestations, reduce intestinal tissue damage, and affect gene expression. Peiminine holds potential as a therapeutic adjunct for the management of ulcerative colitis.

Summary: This study found that melittin peptide, alone or in combination with sulfasalazine, significantly cured clinical ulcerative colitis and attenuated inflammation and tissue damage in colon tissue. Furthermore, this peptide had an antioxidant effect by disrupting the oxidant/antioxidant balance.

Summary: ZBP1 is known for its role in cell death, but it also promotes inflammatory responses to bacterial lipopolysaccharide or double-stranded RNA. ZBP1 facilitates the delivery and ubiquitination of RIPK1, sustaining the activation of inflammatory signaling cascades. This finding highlights the crucial role of ZBP1 in regulating both bacterial and viral responses.

Summary: This study evaluated the clinical effects of probiotic VSL#3 in individuals with symptomatic oral lichen planus. The results showed that VSL#3 was safe and well tolerated, but did not demonstrate significant changes in pain, disease activity, quality of life, serum/salivary CXCL10, or oral microbial composition compared to placebo. Further research is needed to confirm these preliminary findings.

Summary: The study found that long-term use of combined oral contraceptive pills increases the risk of developing inflammatory bowel disease, while progestogen-only pills do not increase the risk of Crohn's disease but may have a modest association with ulcerative colitis. There was no clear association between parenteral progestogen-only contraception and inflammatory bowel disease.

Summary: Climate change is a global emergency that requires policy changes to address industry emissions. The healthcare industry, particularly gastroenterology, has a large and growing carbon footprint due to its reliance on industry. To effectively reduce the field's carbon footprint, serious commitment from the industry is necessary, along with clear guidelines and regulations to control healthcare-related industry emissions and improve sustainability. This narrative review aims to provide practical suggestions for achieving greater sustainability at each step of the supply chain.

Summary: In this study, the first-line low-dose azathioprine-allopurinol co-therapy (LDAA) showed a higher clinical benefit and lower treatment failure rate compared to first-line azathioprine monotherapy (AZAm) in IBD patients without metabolite monitoring. LDAA may be considered as a standard first-line immunosuppressive therapy for improving long-term effectiveness and safety in IBD patients.

Summary: Histological remission is emerging as a key treatment target in UC, and the development of a simple histological index PHRI showed high correlation with endoscopic activity and clinical outcomes. A deep learning AI system based on PHRI accurately predicted histological remission and differentiated active from quiescent UC, with promising sensitivity, specificity, and accuracy results.

Summary: This study investigated the importance of combined endoscopic-histologic remission in predicting clinical outcomes in ulcerative colitis patients. The results showed that at 12 months, there was no significant difference in predicting specified clinical outcomes between endoscopic remission alone and combined endoscopic-histologic remission, but UCEIS combined with histology showed a significant advantage. More studies with specific therapeutic interventions are needed to confirm these findings.
