Objective:To explore the occurrence,co-occurrence,and different subtypes of self-harm and sui-cidal behaviors among male prisoners to inform the development of targeted intervention strategies.Methods:A phenomenology in qualitative research was adopted,and 30 male prisoners with a history of self-harm behaviors,suicidal ideation and suicideattempts,were selected for semi-structured interviews.Data was analyzed by Colaizzi's seven-step method to distill themes.Results:Theme analysis revealed 4 themes and 9 sub-themes(subtypes)of the self-harm and suicidal behaviors of male prisoners,namely the initial occurrence of self-harm behaviors,non-suicid-al self-injury(NSSI)including 6 subtypes(emotional management disorder,self-punishing,antagonistic dissocia-tion,sensation seeking,self-harm without self-awareness,and instrumental self-harm),the co-occurrence of self-harm-suicide behaviors with a subtype of rational suicide,the acute suicide behavior including two subtypes(impul-sive suicide and psychiatric suicide).Conclusion:Negative emotions and emotional dysregulation are important re-lated factorsof self-harm among male prisoners.Suicidal behaviors commonly co-occurred with NSSI,and under-standing the NSSI of prisoners could provide reference for suicide prevention in prisons.There is variability in the motivation of different subtypes of NSSI in maleprisoners,and subtype-based personalized interventions could be a-dopted to reduce the occurrence of self-harm and suicidal behaviors.

Objective To re-evaluate systematic reviews on the application of virtual reality(VR)technology in limb rehabilitation for stroke patients,providing evidence to support the implementation of VR.Methods Systematic searches were conducted in Web of Science,PubMed,CINAHL,Cochrane Library,Embase,CNKI,CBM,WanFang,and VIP databases from their inception until March 2025,identifying systematic reviews/meta-analyses investigating VR for limb rehabilitation in stroke patients.2 researchers independently screened the literature.Methodological quality was evaluated using the Assessment of Mutiple System Reviews 2(AMSTAR 2)tool;reporting quality was evaluated according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses(PRISMA)guidelines;evidence quality was graded using the Grades of Recommendations Assessment,Development,and Evaluation(GRADE)system;literature overlap was assessed using the Corrected Covered Area(CCA)method.Results A total of 15 articles were included.According to AMSTAR 2,totally 3 reviews were of moderate quality,while the remainder were rated as low or very low quality.PRISMA scores ranged from 19.5 to 27.0 points.Based on GRADE,a review was classified as high quality,6 as moderate quality,and the remainder as low or very low quality.The CCA was 5.3％,indicating slight overlap.Conclusion VR contributes to the improvement of indicators such as upper limb motor function/mobility and lower limb balance in stroke patients.However,methodological limitations,including weak control of bias and inadequate handling of heterogeneity among included studies,restrict the overall quality of evidence.Further standardized,high-quality studies are needed to provide more reliable evidence to support clinical decision-making.

Objective To construct a perioperative blood pressure management plan for patients undergoing carotid artery stenting(CAS)and evaluate its application effectiveness,and to provide references for clinical practice.Methods The relevant literature on perioperative blood pressure management for CAS patients was retrieved from domestic and foreign databases,and a preliminary draft of a perioperative blood pressure management plan for CAS patients was constructed.The preliminary draft was discussed and modified through expert meetings,and 2 rounds of expert inquiries were conducted using the Delphi method from June 2023 to August 2023 to determine the final plan.32 patients who received CAS in the neurology department of a tertiary comprehensive hospital in Zhejiang Province were selected from May to July 2024 as an experimental group,and 33 patients who received CAS in the same ward from January to March 2024 as a control group.The experimental group applied the constructed CAS patient perioperative blood pressure management plan,while the control group applied routine perioperative nursing measures.The incidence of postoperative hypertension,postoperative hypotension,and postoperative adverse events was compared between 2 groups.Results A total of 13 experts completed 2 rounds of inquiries.The effective questionnaire response rate for the second round of inquiry was 100％,with an authority coefficient of 0.897.The coefficients of variation for the importance and feasibility scores of each item were 0～0.19 and 0～0.18,respectively,and the Kendall harmony coefficients were 0.224 and 0.201,respectively(P＜0.05).The final construction plan includes 3 primary indicators,15 secondary indicators,and 40 tertiary indicators.Ultimately,32 cases were included in the experimental group and 33 cases in the control group.The incidence of postoperative hypertension,postoperative hypotension,and adverse events in the experimental group was lower than that in the control group,and the difference was statistically significant(P＜0.05).Conclusion The perioperative blood pressure management plan for CAS patients constructed in this study has good scientificity and practicality,which can improve the stability of patients'perioperative blood pressure and reduce the occurrence of adverse events.

The incidence of pediatric inflammatory bowel disease(IBD)is rising,with an especially high proportion of early-onset cases in Asia.Conventional treatments such as glucocorticoids and immunosuppressants have limited efficacy and notable adverse effects,whereas biologic therapies substantially improve remission rates and quality of life.Therapeutic drug monitoring(TDM),by assessing trough concentrations and anti-drug antibodies,enables individualized dose optimization,reduces immunogenicity,and prolongs treatment persistence.However,challenges remain,including insufficient standardization and the lack of pediatric-specific concentration thresholds.This review summarizes recent advances in biologics and TDM in pediatric IBD to inform precision treatment.

The paper presents a case of 69-year-old male with marginal zone lymphoma (MZL) manifesting as acute kidney injury (AKI) requiring emergency hemodialysis. The patient presented with fever, fatigue and rapidly progressive renal dysfunction, and serum creatinine was 1 105 μmol/L. Emergency central venous catheterization and hemodialysis were performed. Serum immunofixation electrophoresis revealed monoclonal IgM and λ light chain positivity. Autoantibody testing showed positivity for both anti-SSA and anti-SSB antibodies. Renal biopsy demonstrated interstitial infiltration by atypical B lymphocytes with λ light chain restriction. The diagnosis of MZL was confirmed by bone marrow biopsy. Following hemodialysis and chemotherapy with bendamustine plus rituximab, renal function significantly improved and remained stable during follow-up. This case highlights that AKI may serve as the initial manifestation of lymphoma, underscoring the importance of considering hematologic malignancies in the differential diagnosis of unexplained renal failure.

Aim To investigate the effect of Brusatol a-gainst small cell lung cancer(SCLC)and its potential mechanism.Methods CCK-8 assay and flow cytome-try were used to detect the cytotoxic effect of Brusatol on SCLC cells.Western blot was employed to measure the expression levels of apoptosis-related proteins,in-cluding cleaved poly(ADP-ribose)polymerase(cleaved-PARP),B-cell lymphoma 2(Bcl-2)and Bcl-2-associated X protein(Bax).Network pharma-cology databases were utilized to identify common tar-gets of Brusatol,SCLC,and apoptosis.Kyoto Encyclo-pedia of Genes and Genomes(KEGG)and Gene On-tology(GO)enrichment analyses were performed on the intersecting genes.Molecular docking simulations between Brusatol and core targets were conducted using the CB-DOCK2 online platform to calculate binding en-ergies and sites.Western blot was further applied to detect the expression levels of signal transducer and ac-tivator of transcription 3(STAT3)and phosphorylated-STAT3(p-STAT3).Results Brusatol inhibited SCLC cell growth and induced apoptosis,significantly downregulating Bcl-2 and cleaved-PARP while upregu-lating Bax expression(P＜0.05).Network pharma-cology analysis revealed 108 common targets of Brusa-tol and SCLC,with the top three core targets being ep-idermal growth factor receptor(EGFR),STAT3,and tumor necrosis factor(TNF).Molecular docking re-sults indicated strong binding affinity between bruceine D and these core targets.Western blot validation con-firmed that bruceine D suppressed the expression of STAT3 and p-STAT3.Conclusion Brusatol exerts anti-SCLC effects by inhibiting STAT3 to induce apop-tosis in SCLC cells.

Pyroptosis is an identified programmed cell death that has been highly linked to endoplasmic reticulum (ER) dynamics. However, the crucial proteins for modulating dynamic ER membrane curvature change that trigger pyroptosis are currently not well understood. In this study, a biotin-labeled chemical probe of potent pyroptosis inducer α-mangostin (α-MG) was synthesized. Through protein microarray analysis, reticulon-4 (RTN4/Nogo), a crucial regulator of ER membrane curvature, was identified as a target of α-MG. We observed that chemically induced proteasome degradation of RTN4 by α-MG through recruiting E3 ligase UBR5 significantly enhances the pyroptosis phenotype in cancer cells. Interestingly, the downregulation of RTN4 expression significantly facilitated a dynamic remodeling of ER membrane curvature through a transition from tubules to sheets, consequently leading to rapid fusion of the ER with the cell plasma membrane. In particular, the ER-to-plasma membrane fusion process is supported by the observed translocation of several crucial ER markers to the "bubble" structures of pyroptotic cells. Furthermore, α-MG-induced RTN4 knockdown leads to pyruvate kinase M2 (PKM2)-dependent conventional caspase-3/gasdermin E (GSDME) cleavages for pyroptosis progression. In vivo, we observed that chemical or genetic RTN4 knockdown significantly inhibited cancer cells growth, which further exhibited an antitumor immune response with anti-programmed death-1 (anti-PD-1). In translational research, RTN4 high expression was closely correlated with the tumor metastasis and death of patients. Taken together, RTN4 plays a fundamental role in inducing pyroptosis through the modulation of ER membrane curvature remodeling, thus representing a prospective druggable target for anticancer immunotherapy.
