AIM: To investigate and clarify the intervention mechanism of trigonelline(TRG)in preventing ferroptosis in ARPE-19 cells based on the Nrf2/HO-1/GPX4 pathway.METHODS: The ARPE-19 cells were cultured and subsequently treated with varying concentrations of trigonelline to ascertain the most effective concentration for modulating the cells. Then the cells were categorized into distinct groups, including normal control(NC)group, high glucose(HG)group, Fer-1 group, TRG group based on the determined concentration. Samples from each group were then gathered to assess relevant indicators. The intracellular levels of glutathione(GSH), malondialdehyde(MDA), and Ferrion were quantified in accordance with the protocols provided by the GSH, MDA, and Ferrion detection kits. Flow cytometry was employed to measure the ROS levels within each group. Additionally, Western blot analysis was conducted to examine the expression of nuclear factor erythroid 2-related factor 2(Nrf2), heme oxygenase-1(HO-1), glutathione peroxidase(GPX4), and acyl-CoA synthetase long-chain family member 4(ACSL4)across the different groups.RESULTS: The preconditioning intervention with 40 μg/mL TRG effectively mitigated the decline in cell activity induced by high glucose levels. The levels of reactive oxygen species(ROS)and MDA in the HG group were markedly elevated compared to the NC group; and the TRG group exhibited significantly reduced levels of ROS and MDA compared to those of the HG group, with the antioxidant stress index GSH showing opposite trends to those of ROS and MDA across all the groups. Whereas the Fer-1 and TRG groups showed decreased expression levels of ACSL4 protein and iron ions, and the expression levels of Nrf2, HO-1 and GPX4 in the Fer-1 and TRG groups were increased.CONCLUSION: TRG protects ARPE-19 cells from the detrimental effects of high glucose by targeting the Nrf2/HO-1/GPX4 signaling pathway to counter ferroptosis.

Inflammatory bowel disease (IBD) is a chronic gastrointestinal inflammatory disorder with unclear etiology. Existing studies indicate that diet plays an important role in both the pathogenesis and prognosis of IBD. This review summarizes clinical evidence regarding the association between diet and the development of IBD, analyze the current nutritional status of the IBD population at the prognosis level and underlying mechanisms of dietary interventions in disease management, and explores the application of precision nutrition in personalized care. The review ultimately aims to provide guidance for developing more precise and personalized dietary management strategies for IBD patients.

his cross-sectional study employed convenience sampling to enroll 1 994 community-dwelling older adults (aged ≥65 years) undergoing health examinations at a Guangzhou community hospital between January and December 2024, aiming to investigate associations between blood lipid profiles and cognitive impairment. Cognitive function was assessed using the AD8 scale, with demographic characteristics (age, sex, education, occupation), health status (hypertension, diabetes mellitus), and lifestyle factors (smoking/alcohol use) collected via questionnaires. Fasting blood samples quantified triglycerides (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C). Propensity score matching (PSM) balanced baseline characteristics between lipid-level groups. Pre-PSM analyses revealed significant intergroup differences: TG groups differed in sex, BMI, alcohol use, hypertension, and self-rated health ( P<0.05); TC groups in sex, age, occupation, diabetes, and hypertension; LDL-C groups in sex, age, occupation, diabetes, hypertension, and daily living ability; HDL-C groups in sex, age, education, occupation, BMI, smoking, diabetes, and hypertension. Post-PSM adjustment eliminated baseline differences ( P>0.05). Multivariable logistic regression adjusted for demographic, clinical, and lifestyle factors demonstrated that elevated TG levels conferred a 48% reduced risk of cognitive dysfunction [ OR (95% CI): 0.52 (0.29-0.94)], whereas TC, LDL-C, and HDL-C showed no significant associations (all P>0.05). These findings suggest an inverse association between higher triglyceride levels and cognitive dysfunction risk in older adults, highlighting TG′s potential protective role in cognitive health.

AIM:To investigate the potential mechanism of licorice on liver injury induced by Se-men Strychni based on network pharmacology,mo-lecular docking combined with animal experiments,providing an effective strategy for prevention and treatment of liver injury induced by Semen Strych-ni.METHODS:Firstly,the active ingredients of Se-men Strychni and licorice were obtained through the ETCM,TCMSP database and analysis platform,CTD database and literature supplementation.Then,the potential toxic ingredients of Semen Strychni were further screened based on the Swis-sADME platform,and the targets corresponding to the active ingredients were predicted through the SwissTargetPrediction platform.By using the Gene-Cards and OMIM databases to collect DILI-related targets,the potential targets for licorice to alleviate liver injury caused by Semen Strychni were ob-tained.By constructing the active ingredient-target network,the core ingredients of licorice in alleviat-ing liver injury caused by Semen Strychni were screened.The key targets obtained were used to construct and analyze the protein-protein interac-tion networks(PPI)through the STRING database and Cytoscape 3.9.0 software.The potential targets were subjected to GO and KEGG pathway enrich-ment analysis with the aid of the DAVID database,and constructed a network of active ingredient-tar-get-pathway.Molecular docking study was ap-proved for the core targets and the active ingredi-ents by using Schrodinger 2023-1 software,and the visualization operation was conducted through Py-mol.Finally,the regulatory effect of licorice on the key pathway of liver injury caused by Semen Strych-ni was validated by establishing a rat model of liver injury induced by Semen Strychni.RESULTS:After screening,6 potential toxic components of Semen Strychni and 104 corresponding targets,89 active components of licorice and 347 corresponding tar-gets,and 3 200 DILI targets were obtained.A total of 23 intersection targets were obtained through Venn analysis.By constructing the active ingredi-ent-target network,it was found that the main core ingredients were 7-methoxy-2-methyl isofla-vone,medicarpin,shinpterocarpin,quercetin,for-mononetin and isoliquiritigenin.The PPI network indicated that the core targets were protein kinase B1(AKT1),epidermal growth factor receptor(EG-FR),human epidermal growth factor receptor 2(ERBB2),glycogen synthase kinase 3 beta(GSK3B),kinase insert domain receptor(KDR)and Janus ki-nase 2(JAK2).A total of 39 relevant pathways were enriched in KEGG(P＜0.01),among which the phos-phatidylinositol 3-kinase(PI3K)-protein kinase B(AKT)(PI3K-AKT)signaling pathway,which has been confirmed and ranks first in enrichment,and was closely related to liver injury.Molecular docking re-sults showed that the core components have good binding ability with the core targets.In vivo animal experiments demonstrated that,compared to the model group,licorice significantly reduced the liver index(P＜0.01),serum levels of alkaline phospha-tase(ALP),alanine aminotransferase(ALT),aspar-tate aminotransferase(AST),indirect bilirubin(IBIL),and total bilirubin(TBIL)in rats with liver in-jury,while increasing total protein(TP)levels(P＜0.05 or P＜0.01).Additionally,licorice alleviated con-gestion in the central veins and hepatic sinusoids,improved the alignment of hepatocytes,and re-duced inflammatory cell infiltration.Furthermore,licorice significantly decreased the levels of malo-ndialdehyde(MDA),tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β),and interleukin-6(IL-6)in the liver tissue of injured rats,while elevating the levels of superoxide dismutase(SOD)and glutathi-one peroxidase(GSH-Px)(P＜0.01).It also markedly downregulated the phosphorylation levels of PI3K and AKT(P＜0.01).CONCLUSION:Licorice has multi-component and multi-target properties in the treat-ment of liver injury induced by Semen Strychni,which may play a hepatoprotective role by inhibit-ing the activation of PI3K-AKT signaling pathway.

Objective To explore the correlation of neutrophil/lymphocyte ratio(NLR),monocyte/high density lipoprotein cholesterol ratio(MHR)and mild cognitive impairment(MCI)in patients with type 2 diabetes mellitus(T2DM).Methods 159 T2DM patients hospitalized in the Department of Endocrinology,Affiliated Hospital of Xuzhou Medical University from February 2023 to April 2023 were selected.The subjects were divided into normal cognitive function(Con,n=72)group and MCI group(n=87)based on score of Montreal cognitive assessment scale(MoCA).NLR and MHR were calculated and compared between the two groups.Spearman correlation analysis was used to analyze the correlation between NLR,MHR and MoCA score.Logistic regression analysis of the factors influencing the association between T2DM with MCI.Receiver operator characteristic(ROC)curve was used to evaluate the predictive value of NLR and MHR for DM complicated with MCI.Results Compared with Con group,MCI group showed a significant increase in hemoglobin A1c(HbA1c),fasting plasma glucose,NLR,MHR,neutrophil count,monocyte count,serum creatinine,cystatin C,while high density lipoprotein cholesterol lymphocytes,visual space and executive function,naming,attention,language ability,abstract thinking,delayed memory,orientation and MoCA score decreased(P＜0.05).Spearman correlation analysis showed that there was a negative correlation between MHR,NLR and MoCA score,visuospatial and executive function,delayed recall and attention.Logistic regression analysis showed that NLR,MHR,HbA1c were all risk factors for MCI in T2DM.ROC curve analysis showed that the area under the curve of NLR combined with MHR for diagnosing T2DM with MCI was 0.872,with corresponding sensitivity of 81.6%and specificity of 87.5%.Conclusions NLR and MHR are closely related to MCI in T2DM patients.The combination of NLR and MHR have certain efficacy in prediction T2DM with MCI.
