ObjectiveTo observe the activation patterns and functional connectivity in the prefrontal cortex of patients with post-stroke anxiety (PSA) using functional near-infrared spectroscopy, in order to explore the underlying neural mechanism. MethodsFrom December, 2024 to September, 2025, 120 stroke patients were selected in Changzhou De'an Hospital. They were divided into PSA group (n = 60) and non-PSA group (n = 60) according to the score of Hamilton Anxiety Scale (HAMA). All patients wore an 18-channel fNIRS acquisition cap for detection. The differences in resting-state functional connectivity between the frontopolar cortex (FPC) and dorsolateral prefrontal cortex (DLPFC) were examined in both groups, as well as task-related activation in these brain regions. ResultsResting-state functional connectivity analysis revealed no statistically significant difference in network connectivity between two groups in the FPC and DLPFC regions (|t| < 1.301, P > 0.05). Task-related activation results revealed significantly reduced activation in the contralateral FPC of PSA group compared to the non-PSA group (Z = -2.063, P < 0.05). Activation levels in this region showed a negative correlation with the scores of HAMA (ρ = -0.201, P = 0.028). ConclusionActivation decreased in the contralateral frontal pole during the task state for patients with PSA, and the activation levels negatively correlates with anxiety severities.

Hearing loss is the most prevalent disabling disease. Cochlear implantation（CI） serves as the primary intervention for severe to profound hearing loss. This consensus systematically explores the value of genetic diagnosis in the pre-operative assessment and efficacy prognosis for CI. Drawing upon domestic and international research and clinical experience, it proposes an evidence-based medicine three-tiered prognostic classification system（Favorable, Marginal, Poor）. The consensus focuses on common hereditary non-syndromic hearing loss（such as that caused by mutations in genes like GJB2, SLC26A4, OTOF, LOXHD1） and syndromic hereditary hearing loss（such as Jervell & Lange-Nielsen syndrome and Waardenburg syndrome）, which are closely associated with congenital hearing loss, analyzing the impact of their pathological mechanisms on CI outcomes. The consensus provides recommendations based on multiple round of expert discussion and voting. It emphasizes that genetic diagnosis can optimize patient selection, predict prognosis, guide post-operative rehabilitation, offer stratified management strategies for patients with different genotypes, and advance the application of precision medicine in the field of CI.

Most cancers are currently incurable, partly due to abnormal post-translational modifications (PTMs). In this study, we initially used multiple myeloma (MM) as a working model and found that SUMOylation activating enzyme subunit 1 (SAE1) promotes the malignancy of MM. Through proteome microarray analysis, SAE1 was identified as a potential target for bioactive colcemid or its derivative colchicine. Elevated levels of SAE1 were associated with poor clinical survival and increased MM proliferation in vitro and in vivo. Additionally, SAE1 directly SUMOylated and upregulated the total protein expression of p27, leading to LLPS-mediated nuclear export of p27. Our study also demonstrated the involvement of SAE1 in other types of cancer cells, and provided the first monomer crystal structure of SAE1 and its key binding model with colchicine. Colchicine also showed promising results in the Patient-Derived Tumor Xenograft (PDX) model. Furthermore, a controlled clinical trial with 56 MM patients demonstrated the clinical efficacy of colchicine. Our findings reveal a novel mechanism by which tumor cells evade p27-induced cellular growth arrest through p27 SUMOylation-mediated nuclear export. SAE1 may serve as a promising therapeutic target, and colchicine may be a potential treatment option for multiple types of cancer in clinical settings.

Objective: To examine the casual association between age at first sexual intercourse and gynecologic malignant tumors using Mendelian randomization (MR) approach. Methods: The single nucleotide polymorphisms (SNPs) associated with age at first sexual intercourse were obtained from a meta-analysis of genome-wide association study (GWAS), and the SNPs related to gynecologic malignant tumors (ovarian cancer, endometrial cancer, cervical cancer), and their subtypes were sourced from the IEU OpenGWAS database. Using age at first sexual intercourse as the exposure and gynecologic malignant tumors as the outcome, a MR analysis was performed with the inverse-variance weighted (IVW) method. Heterogeneity was assessed using Cochran's Q test, horizontal pleiotropy was evaluated using MR-Egger regression and MR-PRESSO test, and bias was examined using funnel plots. Results: The Mendelian randomization analysis demonstrated that younger age at first sexual intercourse was significantly associated with an increased risk of low-grade serous ovarian carcinoma (OR=0.553, 95%CI: 0.335-0.911), cervical cancer (OR=0.674, 95%CI: 0.466-0.974), endometrial cancer (OR=0.854, 95%CI: 0.730-0.999), and endometrioid carcinoma (OR=0.830, 95%CI: 0.690-0.998). No statistical association was found between the age at first sexual intercourse and ovarian cancer, high-grade serous ovarian cancer, mucinous ovarian cancer, endometrioid ovarian cancer, or non-endometrioid ovarian cancer (all P>0.05). Sensitivity analysis showed no evidence of undetected instrumental variable heterogeneity or horizontal pleiotropy (all P>0.05), and the funnel plot indicated no presence of bias. Conclusion Younger age at first sexual intercourse may be associated with an increased risk of certain gynecologic malignant tumors, highlighting the need to strengthen adolescent sex education.

Objective To investigate the causal relationship between gut microbiota and viral pneumonia,as well as the underlying mechanisms,using two-sample and two-step Mendelian randomization(MR)approaches,thereby providing novel insights for the prevention and treatment of viral pneumonia.Methods All data were obtained from publicly available genome-wide association studies(GWAS)pooled datasets,including gut microbiota data from the MiBioGen Consortium and the Netherlands Microbiome Project,viral pneumonia data from the FinnGen R10 database,and plasma metabolome data from the publicly available GWAS Catalog.Instrumental variables(IVs)were extracted according to the predefined threshold values.MR analyses were conducted using inverse variance weighting(IVW),MR-Egger,weighted median(WME),weighted mode(WM),and Bayesian-weighted Mendelian randomization(BWMR)methods.Reverse MR analysis was performed to determine whether there was a reverse association.Two-step MR analysis was used to explore the potential mediating role of plasma metabolites,and a series of sensitivity analyses were performed to test the stability of the results.Results Among 196 gut microbiota taxa from the MiBioGen consortium GWAS,11 taxa were associated with viral pneumonia.An increase in the abundance of 4 taxa increased the risk of viral pneumonia,while an increase in the abundance of 7 taxa had a protective effect against viral pneumonia.Among the 207 gut microbiota taxa from the Dutch Microbiome Project GWAS data,10 taxa were associated with viral pneumonia,with 6 risk-increasing and 4 protective taxa identified.Mediation analysis results showed that the causal effect of Defluviitaleaceae on viral pneumonia(OR=0.708,95%CI 0.540-0.929,P=0.013)was mediated to some extent by the N6-acetyllysine levels,with a mediation ratio of 18.4%.Sensitivity analyses did not reveal significant heterogeneity or horizontal pleiotropy.Conclusions Specific gut microbiota are causally associated with viral pneumonia and show potential differences across different populations;the protective effect of Defluviitaleaceae against viral pneumonia may be mediated by the N6-acetyllysine levels.Targeting metabolites may become a potential therapeutic approach for viral pneumonia.

Objective This research was performed to identify rodent-borne pathogens in Hekou Port,Yunnan Province.Methods Rodents were captured using cages and dissected to collect their lungs,liver,spleen,and other viscera.Eight pathogens,including Yersinia pestis,Leptospira,Bartonella,and Anaplasmataceae,were identified using polymerase chain reaction amplification.Amplified pathogen sequences from positive samples were sequenced,and BLAST homology searches were conducted using GenBank to confirm pathogen identities.A phylogenetic tree of the identified pathogens was constructed using the neighbor joining method.Results The total of 31 rodents,identified as Rattus tanezumi,R.norvegicus,and Mus musculus,were captured.Among these,R.tanezumi was the dominant species,accounting for 64.52％of the total.Two pathogens,Leptospira interrogans and Neoehrlichia mikurensis,were detected,with positivity rates of 9.68％and 29.03％,respectively.No other pathogens were detected.The overall positivity rate for rodent-borne pathogens was 35.48％.Conclusions The single 16S rRNA gene fragment is insufficient for the molecular identification of all Neoehrlichia species.Accurate species identification should be based on a combined analysis of multiple genes.The prevalence of rodent-borne pathogens in Hekou Port indicates the necessity for enhanced surveillance of rodent-borne diseases and implementation of additional prevention and control measures in border ports.

Objective To analyze the publication condition and development trends of global post-stroke fatigue(PSF)research from 2004 to 2024.Methods Relevant literature on PSF pub-lished between January 1,2004,and August 1,2024,were systematically searched and screened from WoSCC database.Visual analysis of publication volume,contributing countries,institutions,authors,and keywords in PSF research was conducted using CiteSpace software.Results A total of 373 articles were included in this study.The overall publication volume related to PSF exhibited an upward trend.The country,institution,and author with the highest number of publications were the United Kingdom,the University of Oslo,and LERDAL A,respectively.High-frequency keywords in-cluded quality of life,depression,fatigue severity scale,follow up,epidemiology,symptoms,associ-ations,and rehabilitation,while the emerging keywords were health care professionals,risk factors,and participation.Conclusion PSF-related research has demonstrated an overall upward trend.As-sessment and measurement protocols,rehabilitation treatment approaches,impacts on quality of life,and the intrinsic relationship with depression have emerged as research hotspots.Further exploration of precise and systematic assessment methods,along with the construction of scientific rehabilitation management programs and risk prediction models,will become the focal points of future research.

Photothermal therapy,as a novel anti-tumor treatment strategy,faces many challenges such as insufficient targeting,limited penetration ability,and inability to achieve long-term inhibition when used alone for anti-tumor treatment.Based on this,in this study,macrophage extracellular vesicles(MEVs)were modified onto the surface of a vector carrying CSF1R-siRNA and photothermal agents to form a multifunctional gene delivery vector MEVs@RNPs.It could induce the macrophages to reprogram from M2 type to M1 type,so as to achieve efficient photothermal and immunotherapy for triple negative breast cancer(TNBC).The basic physicochemical properties of each nanocarrier were characterized using nanoparticle size analyzer,UV-vis spectrometer,fluorescence spectrometer,thermal imaging instrument,etc.TNBC cells 4T1,endothelial cells Bend3,and macrophages 264.7 were used as in vitro experimental subjects for measurement of MEVs@RNPs.The ability to target tumor cells,kill tumor cells,and induce macrophage reprogramming in vitro was investigated.With Balb/c mice as the in vivo research object,a subcutaneous transplant tumor model was established in mice,and the changes in tumor volume and body weight of mice in different treatment groups were measured.In addition,further isolation of mouse blood and tumor tissue was performed,and hematoxylin-eosin(HE)staining,terminal deoxynucleotidyl transferase dUTP nick end labeling(TUNEL)method,and enzyme-linked immunosorbent assay(ELISA)method were used to determine the apoptosis and cytokine secretion of tumor cells for comprehensive evaluation of MEVs@RNPs.The results showed that the MEVs@RNPs could preferentially target tumor cells and induce stronger TNBC cell killing effect under photothermal conditions.Meanwhile,the results of flow cytometry and ELISA analysis showed that the MEVs@RNPs could promote the transformation of macrophages from M2 type to anti-tumor M1 type,significantly enhancing the secretion levels of anti-tumor cytokines tumor necrosis factor-α(TNF-α)and interleukin-12(IL-12).The in vivo anti-tumor treatment effect assessment of the MEVs@RNPs showed that under laser processing conditions,the MEVs@RNPs could significantly induce pathological necrosis and apoptosis of tumor cells,promote macrophage reprogramming and infiltration of CD4+/CD8+T cells into the tumor site,and enhance the secretion levels of TNF-α and IL-12,thereby comprehensively improving the therapeutic effect of TNBC.
