Objective To investigate the risk factors for complications within 1 year after carotid artery stenting(CAS),construct a prediction model for these complications based on the identi-fied risk factors,and then validate the efficacy of the model.Methods A retrospective trial was conducted on 313 patients undergoing CAS in our hospital between January 2017 and December 2021.Based on the sequence of postoperative follow-up visits,these patients were categorized into a modeling group(235 cases)and a validation group(78 cases)in a ratio of 3∶1,and the patients of the modeling group was further assigned into non-complication(182 cases)and complication subgroups(53 cases).The general data were compared between the modeling and balidation groups,and univariate and multivariate logistic regression analyses were applied to identify risk factors for the risk factors for the complications,and then a prediction model was constructed using logistic scoring.ROC curve analysis was employed to evaluate the performance of the model by using AUC value.Results Multivariate logistic regression analysis revealed that non-compli-ance with antiplatelet medication(OR=65.656,95％CI:12.052-357.683,P=0.000),and abnor-mal BMI(OR=2.298,95％CI:1.023-5.163,P=0.044),cigarette history(OR=5.965,95％CI:2.527-14.079,P=0.000),and high LDL-C(OR=6.290,95％CI:1.828-21.645,P=0.004)were independent risk factors for complications occurrence within 1 year after CAS surgery.The AUC value was 0.827 for the modeling group and 0.806 for the validation group.Conclusion Non-com-pliance to antiplatelet medication,abnormal BMI,smoking history,and high LDL-C level are inde-pendent risk factors for complications occurrence within 1 year after CAS.Our developed ABCD risk prediction model demonstrates good discrimination and accuracy,and can provide valuable guid-ance for the early identification and prevention of complications following CAS surgery in clinical practice.

Aim To explore the mechanism of action of Ruanmai decoction in treating atherosclerosis through network pharmacology. Methods The chemical components and targets of Ruanmai decoction were queried using TCMSP. Relevant targets for atherosclerosis were retrieved from DrugBank, GeneCards, OMIM, and TTD databases. The " Drug-Active Ingredient-Target" PPI network was constructed using Cyto-scape software. GO and KEGG enrichment analysis were performed using the David database. Molecular docking verification of key components with core targets was conducted using the Seesar software. Atherosclerosis mouse models were established by feeding ApoE mice with a high-fat diet, and Ruanmai decoction granules were administered orally. Aortic pathological sections were stained, blood lipids were measured, and immunofluorescence was used to detect Mac2 and YWHAZ protein expression. Western blot was used to detect p-p38MAPK and C-CASP3 protein expression. Results Ruanmai decoction screened a total of 72 active drug components corresponding to 168 target genes for the treatment of atherosclerosis. The targets were primarily enriched in biological processes related to lip-id metabolism, inflammation and immunity, oxidative stress, vascular endothelial function, cell proliferation and apoptosis, glycolysis, and ubiquitination. Signaling pathways such as МАРК, TNF, PDK-Akt, and IL-17 were also involved. Animal experiments verified that RMJ could regulate the p38MAPK signaling pathway by down-regulating key targets YWHAZ, p-p38MAPK, and C-CASP3, thereby reducing AS inflammation and inflammation-induced apoptosis. Conclusions Ruanmai decoction can inhibit the expression of YWHAZ and activate the p38MAPK signaling pathway, potentially improving vascular inflammation, lipid metabolism, oxidative stress, and other pathological processes by regulating the МАРК, TNF, PDK-Akt, and IL-17 signaling pathways, thus preventing and treating atherosclerosis.

Objective:To investigate whether long non-coding RNA(lncRNA) AW112010 can improve insulin resistance in aging adipocytes through the miR-204/POU2F2 signaling pathway.Methods:In vivo experiment: C57BL/6 mice were divided into young control group(4 months old) and aging model group(18 months old) based on body weight. The expression levels of AW112010, miR-204-5p, POU2F2, aging related indicators(p16, p21), and insulin signaling pathway genes [insulin receptor(INSR), insulin receptor substrate 1(IRS1), phosphatidylinositol kinase(PI3K), protein kinase B(AKT)] in epididymal adipose tissue were detected using real-time fluorescence quantitative PCR(RT-qPCR) and Western blotting. In vitro experiment: Using adriamycin(ADR) to induce 3T3-L1 aging adipocyte model, β-gal staining was used to observe cellular senescence, and miR-204 inhibitor and miR-204 mimic small interfering RNA were successfully constructed and transfected into 3T3-L1 adipocytes. Results:RT-qPCR and Western blot results showed that compared with the young group, the expression of AW112010 in the adipose tissue of aging mice was increased, while the expression of miR-204-5p was decreased. The expressions of POU2F2, p16, and p21 in the adipose tissue of aging mice were increased, while the expressions of INSR, IRS1, PI3K, GLUT4 mRNA and protein were decreased. The β-gal stainging results showed that the number of 3T3-L1 senescent adipocytes induced by ADR was significantly increased, and the expression levels of AW112010, POU2F2, p16, and p21 in ADR-induced senescent adipocytes were increased compared with the control group, while the expression levels of miR-204-5p, INSR, IRS1, PI3K, GLUT4 were decreased, and remaining glucose in the culture medium was increased. Compared with control, overexpression of miR-204 resulted in decreased expressions of aging indicators p16, p21, and target gene POU2F2 while the expressions of INSR and GLUT4 were increased.Conclusion:Upregulation of lncRNA AW112010 in adipocytes of aging mice may induce insulin resistance by targeting miR-204-5p/POU2F2/IRS1.
