To investigate the efficacy and safety of glucocorticoids combined with cyclophosphamide (CTX) and rituximab (RTX) in elderly patients with anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis with renal involvement. Elderly patients (age ≥60 years) with ANCA-associated vasculitis and renal involvement admitted to the First Affiliated Hospital, Zhejiang University School of Medicine from December 2019 to November 2022 were retrospectively enrolled. Based on different induction treatment regimens, patients were divided into a control group (glucocorticoids + CTX) and a combination therapy group (glucocorticoids + CTX + RTX). Differences in disease remission, end stage renal disease (ESRD), mortality, relapse, and incidence of adverse events were compared between the two groups. A total of 60 elderly patients with ANCA-associated vasculitis and renal involvement were ultimately included, with a median follow-up of 29.7(17.2, 38.7) months. The control group comprised 26 patients, with a median follow-up of 35.0(28.1, 40.3) months; the combination therapy group comprised 34 patients, with a median follow-up of 26.2(16.1, 35.1) months. The remission rate at 3 months (64.7% For elderly patients with ANCA-associated vasculitis and renal involvement, the regimen of glucocorticoids combined with CTX and individualized RTX demonstrates potential advantages in early remission rate, glucocorticoid tapering, and control of cumulative CTX dose, without increasing the risk of serious adverse events. This regimen may represent an alternative treatment option for this patient population; however, its long-term efficacy and safety require further validation through prospective randomized controlled trials.

Objective:To evaluate the efficacy and safety of rituximab (RTX) in the treatment of idiopathic membranous nephropathy (IMN), explore the influencing factors of the therapeutic effect and construct a nomogram model for predicting the therapeutic effect.Methods:A single retrospective study was conducted in IMN patients in the First Affiliated Hospital of Zhejiang University School of Medicine from January 2017 to December 2022. All patients received monotherapy with RTX and were followed up for at least 12 months. RTX regimen adopted a B-cell guided regimen to achieve 0 cells/μl of peripheral blood CD19+ B cells through multiple administrations, followed by monitoring every 2?3 months and adding doses as needed to maintain this state. The complete response rate, partial response rate, and composite response rate at 6 months, 12 months and the end of follow up were analyzed. Logistic stepwise regression and R language were applied to construct a nomogram model for efficacy prediction. The receiver operating characteristic (ROC) curve, calibration curve and Hosmer-Lemeshow test were used to internally validate the nomogram model.Results:A total of 147 IMN patients were included in the study, with age of 56 (47, 65) years, 99 (67.4%) males. There were 69 (46.9%) newly treated patients, 78 (53.1%) retreatment patients. The follow-up time was 14.4 (12.0, 15.0) months. The total RTX dose was 1 800 (1 200, 2 400) mg. The composite response rates at 6 months, 12 months and the end of the follow-up were 36.7% (54/147), 59.9% (88/147) and 63.3% (93/147), respectively. The complete remission rates at 6 months, 12 months and the end of the follow-up were 6.1% (9/147), 13.6% (20/147) and 19.7% (29/147), respectively. Logistic stepwise regression analysis showed that age ≥ 65 years ( OR=0.335, 95% CI 0.135?0.833), retreatment ( OR=0.333, 95% CI 0.144?0.771), high cholesterol ( OR=0.716, 95% CI 0.577?0.888), high serum creatinine ( OR=0.978, 95% CI 0.963?0.993) and B-cell reconstruction within 6 months ( OR=0.273, 95% CI 0.115?0.645) were independent correlated factors affecting composite remission. Based on these factors, a nomogram model for predicting the therapeutic effect of RTX in IMN patients was constructed. The ROC curve indicated that the accuracy of this model in predicting composite remission was good ( AUC=0.814, 95% CI 0.744-0.883). The calibration curve showed that the predicted composite response rate had a good fit with the actual response rate (Hosmer-Lemeshow test χ2=11.917, P=0.155). Conclusions:RTX has good efficacy and safety as a monotherapy for IMN patients. The constructed nomogram prediction model has high discrimination and accuracy to predict the efficacy of RTX treatment for IMN.

Objective:
To construct and validate a prognostic model for lung cancer based on acrolein-related genes using bioinformatics methods .
Methods:
Lung cancer datasets GSE30219 and GSE68465 were obtained from the GEO database , and acrolein-related gene sets were retrieved from the CTD database . Differentially expressed genes (DEGs) between cancer and adjacent tissues were identified in the GSE30219 dataset. The intersection of these DEGs and acrolein-related genes was then used to identify candidate genes . Gene set variation analysis ( GSVA) was performed to assess functional alterations based on the intersection genes . A protein-protein interaction (PPI) network was constructed based on the STRING database to identify core hub genes . Subsequently , support vector machine recursive feature elimination (SVM-RFE) and LASSO-Cox regression analyses were employed to develop a prognostic model based on acrolein-related genes , which was independently validated using the GSE68465 dataset. The CIBERSORT algorithm was applied to evaluate the immune cell infiltration characteristics between high- and low-risk groups , and functional enrichment analysis of DEGs between the two groups was conducted to further ex- plore the potential molecular mechanisms underlying the prognostic model .
Results :
A total of 361 acrolein-related DEGs were identified in lung cancer , and 7 key genes were selected for model construction . Kaplan-Meier survival analysis revealed that patients in the high-risk group had significantly lower survival rates compared to those in the low-risk group (P < 0. 000 1) . Receiver operating characteristic (ROC) curve analysis demonstrated that the mod- el possessed good predictive performance . Moreover , immune infiltration analysis indicated that the risk score was closely associated with multiple immune cell subsets , suggesting a potential role of acrolein-related genes in modula- ting the lung cancer immune microenvironment.
Conclusion
The prognostic model for lung cancer based on acro- lein-related genes demonstrates significant application value in predicting the prognosis of lung cancer , providing new insights into the potential mechanisms of acrolein in the onset and progression of lung cancer.
