Abstract
Rapid drug clearance and off-target effects of therapeutic drugs can induce low bioavailability and systemic side effects and gravely restrict the therapeutic effects of inflammatory bowel diseases (IBDs). Here, we propose an amplifying targeting strategy based on orally administered gallium (Ga)-based liquid metal (LM) nano-agents to efficiently eliminate reactive oxygen and nitrogen species (RONS) and modulate the dysregulated microbiome for remission of IBDs. Taking advantage of the favorable adhesive activity and coordination ability of polyphenol structure, epigallocatechin gallate (EGCG) is applied to encapsulate LM to construct the formulations (LM-EGCG). After adhering to the inflamed tissue, EGCG not only eliminates RONS but also captures the dissociated Ga to form EGCG-Ga complexes for enhancive accumulation. The detained composites protect the intestinal barrier and modulate gut microbiota for restoring the disordered enteral microenvironment, thereby relieving IBDs. Unexpectedly, LM-EGCG markedly decreases the Escherichia_Shigella populations while augmenting the abundance of Akkermansia and Bifidobacterium, resulting in favorable therapeutic effects against the dextran sulfate sodium-induced colitis.

Shi X, Geng L. Chronic illness trajectory-based nursing intervention improves the self-care abilities of patients with inflammatory bowel disease. Am J Transl Res 2024; 16:2579-2588. [PMID: 39006252 PMCID: PMC11236649 DOI: 10.62347/qeoo2698] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2024] [Accepted: 05/14/2024] [Indexed: 07/16/2024]
Abstract
OBJECTIVE To explore the effects of chronic illness trajectory model (CITM)-based nursing interventions on anxiety, depression, quality of life, medication adherence, and dietary compliance among patients with inflammatory bowel disease (IBD). METHODS A retrospective analysis was performed on 112 IBD patients admitted to Shandong Provincial Hospital Affiliated to Shandong First Medical University from January to December 2023. Patients were divided into two groups: a control group (n=62) receiving routine nursing care, and an observation group (n=50) receiving CITM-based nursing care. Assessments of anxiety, depression, self-care ability, daily living ability, and symptom severity were conducted before and after the intervention. RESULTS Post-intervention, the observation group demonstrated significantly higher quality of life scores at 1 and 3 months compared to the control group (both P<0.05). Additionally, the observation group showed improved medication adherence and lower symptom scores, with significant differences (both P<0.05). Anxiety and depression levels were also significantly reduced in the observation group compared to the control group (both P<0.05). CONCLUSION CITM-based nursing intervention significantly enhances self-care abilities, quality of life, and compliance with medication and dietary regimens in IBD patients. Furthermore, it effectively alleviates anxiety and depression, supporting comprehensive management of this chronic disease.

Front Immunol 2024; 15:1334395. [PMID: 38449867 PMCID: PMC10915022 DOI: 10.3389/fimmu.2024.1334395] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2023] [Accepted: 02/02/2024] [Indexed: 03/08/2024] Open
Abstract
Background Previous studies have shown conflicting results regarding the impact of circulating antioxidants on the risk of inflammatory bowel disease (IBD). In this study, our intent was to investigate the causal relationship between circulating antioxidants and IBD using Mendelian randomization (MR). Methods Instrumental variables for absolute circulating antioxidants (ascorbate, retinol, lycopene, and β-carotene) and circulating antioxidant metabolites (α-tocopherol, γ-tocopherol, ascorbate, and retinol) were screened from published studies. We obtained outcome data from two genome-wide association study (GWAS) databases, including the international inflammatory bowel disease genetics consortium (IIBDGC, 14,927 controls and 5,956 cases for Crohn's disease (CD), 20,464 controls and 6,968 cases for ulcerative colitis (UC), and 21,770 controls and 12,882 cases for IBD) and the FinnGen study (375,445 controls and 1,665 cases for CD, 371,530 controls and 5,034 cases for UC, and 369,652 controls and 7,625 cases for IBD). MR analysis was performed in each of the two databases and those results were pooled using meta-analysis to assess the overall effect of exposure on each phenotype. In order to confirm the strength of the findings, we additionally conducted a replication analysis using the UK Biobank. Results In the meta-analysis of the IIBDGC and FinnGen, we found that each unit increase in absolute circulating level of retinol was associated with a 72% reduction in the risk of UC (OR: 0.28, 95% CI: 0.10 to 0.78, P=0.015). The UC GWAS data from the UK Biobank also confirmed this causal relationship (OR: 0.99, 95% CI: 0.97 to 1.00, P=0.016). In addition, there was suggestive evidence that absolute retinol level was negatively associated with IBD (OR: 0.41, 95% CI: 0.18 to 0.92, P=0.031). No other causal relationship was found. Conclusion Our results provide strong evidence that the absolute circulating level of retinol is associated with a reduction in the risk of UC. Further MR studies with more instrumental variables on circulating antioxidants, especially absolute circulating antioxidants, are needed to confirm our results.

Chem Biodivers 2023; 20:e202301806. [PMID: 38009836 DOI: 10.1002/cbdv.202301806] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Revised: 11/23/2023] [Accepted: 11/24/2023] [Indexed: 11/29/2023]
Abstract
Picroside III (Pic), an iridoid glycoside derived from Picrorhiza scrophulariiflora, exhibits therapeutic potential in mending damage to the intestinal mucosa. This study aimed to explore Pic's regulatory impact on intestinal inflammation and the gut microbiota in mice with dextran sulfate sodium (DSS)-induced colitis. The findings revealed that pretreatment with Pic mitigated the DSS-induced escalation of the disease activity index (DAI), alleviated intestinal damage, and attenuated intestinal inflammation in mice. RNA-seq analysis, complemented by experimental validation, elucidated that Pic significantly hindered Akt phosphorylation in the colon tissues of colitis-afflicted mice. Furthermore, 16S rRNA sequencing demonstrated that Pic pretreatment effectively rectified microbial dysbiosis in colitis mice by elevating the abundance of Lactobacillus murinus and Lactobacillus gasseri. These observations suggest that Pic's efficacy in colitis treatment stems from its inhibition of intestinal inflammation via the suppression of the PI3K-Akt pathway and modulation of gut microbiota. This study contributes novel scientific insights into the potential application of Pic in the management of inflammatory bowel disease (IBD).
