A 51-year-old male presented with nasal obstruction, followed by progressive hearing loss and blurred vision. Imaging identified space-occupying lesions in the paranasal sinuses, orbits, and paraspinal regions, while laboratory tests confirmed positive anti-proteinase 3 anti-neutrophil cytoplasmic antibody(PR3- ANCA) immunoglobulin G (IgG)and markedly elevated serum IgG4. Despite treatment with corticosteroids, immunosuppressants, and radiotherapy, the patient exhibited steroid dependency with relentless disease progression. Following multidisciplinary consultation, a diagnosis of inflammatory myofibroblastic tumor (IMT) coexisting with ANCA- associated vasculitis (AAV) was favored, though IgG4-related disease remained a critical differential. Ultimately, profound immunosuppression precipitated a severe herpesvirus infection, leading to disseminated intravascular coagulation and multiple organ dysfunction syndrome. This case underscores the rarity and diagnostic complexity of concurrent IMT and AAV, highlights the therapeutic dilemma of balancing primary disease control against fatal opportunistic infections, and emphasizes the critical role of multidisciplinary collaboration in the diagnosis and treatment of complex diseases.

Current experimental and computational methods have limitations in accurately and efficiently classifying ion channels within vast protein spaces. Here we have developed a deep learning algorithm, GPT2 Ion Channel Classifier (GPT2-ICC), which effectively distinguishing ion channels from a test set containing approximately 239 times more non-ion-channel proteins. GPT2-ICC integrates representation learning with a large language model (LLM)-based classifier, enabling highly accurate identification of potential ion channels. Several potential ion channels were predicated from the unannotated human proteome, further demonstrating GPT2-ICC's generalization ability. This study marks a significant advancement in artificial-intelligence-driven ion channel research, highlighting the adaptability and effectiveness of combining representation learning with LLMs to address the challenges of imbalanced protein sequence data. Moreover, it provides a valuable computational tool for uncovering previously uncharacterized ion channels.

Objective:To analyze the depressive symptoms of physical and mental workers and the impact of their behavior and lifestyle on their depressive symptoms.Methods:In August 2022, a cross-sectional study design was adopted to select 553 workers as research subjects using cluster sampling. General demographic information, health-related behaviors and lifestyles were collected, and their depressive symptoms were evaluated using the Chinese version of the Patient Health Questionnaire 9 (PHQ-9). The differences in general demographic information, health-related behaviors and lifestyles between physical and mental workers were analyzed, and logistic regression was used to analyze the influencing factors of depressive symptoms in occupational populations.Results:Among the 553 subjects, 317 were physical workers (57.32%) and 236 were mental workers (42.68%). Statistically significant differences were observed between the two groups in terms of education level, monthly income, smoking rate, regular physical exercise rate and appropriate sleep time rate ( P<0.05). The score and the detection rate of depression symptoms among physical workers were (9.67±2.75) points and 20.82% (66/317), respectively, which were higher than those of mental workers [(8.34±2.18) points, 12.71% (30/236) ] ( t=6.13, χ 2=6.20, P<0.05). The results of logistic regression analysis showed that smoking, regular physical exercise, appropriate sleep time and mental work were influencing factors of depressive symptoms among the occupational population ( OR=1.592, 95% CI: 1.316-1.825; OR=0.659, 95% CI: 0.416-0.830; OR=0.502, 95% CI: 0.257-0.717; OR=0.839, 95% CI: 0.522-0.967; P<0.05) . Conclusion:The depressive symptoms of physical workers are more serious than those of mental workers. Low education level, not frequently participating in physical exercise, smoking and sleep disorder are potential risk factors that affect the depressive symptoms of the occupational population.

Objective To analyze the problems existing in the homogenization management of multi-branch hospitals based on the annual performance assessment data,and provide reference for promoting the high-quality development of public hospital branch districts.Methods Based on the Performance Assessment Operation Manual of National Tertiary Public Hospitals(2022 edition),10 indicators including the proportion of discharged patients undergoing surgery and the proportion of fourth-level surgery were screened,and the functional positioning,quality and safety,revenue and expenditure structure,and cost control of 4 hospitals of a certain medical institution from 2022 to 2023 were descriptively analyzed.Results The CMI value and the proportion of discharged surgery in the main hospital were significantly better than those in the branch hospitals,and there was no significant difference in the medical quality indicators of the four hospitals,and the operation efficiency of the branch hospital with outstanding specialty characteristics was better than that of other hospitals.Conclusion Public hospitals pay more attention to the"big specialty,small comprehensive"mode in the layout of branch districts,pay more attention to the quality control management at the specialty level in medical quality management,and strengthen the benefit analysis of different hospitals in the same specialty in operation management.

Objective To investigate the effect of spleen on hepatic macrophages mediated activation of hepatic stellate cells(HSCs)in mice with liver fibrosis.Methods Eighteen male C57BL/6 mice were randomly divided into three groups.Mice in Group A and Group B were injected intraperitoneally with CCl4 to establish liver fibrosis mouse model,while those in Group C were injected with corn oil as normal control.Four weeks later,mice with liver fibrosis received splenectomy(Spx)or sham operation(Sham),respectively.After continuous injection for 2 weeks,liver homogenates(L-Homo)were prepared and liver cells were isolated from the three groups.Expressions of IL-1β,IL-13,TGF-β,TNF-α,PDGF-β and VEGF in the liver homogenates of the three groups were detected by Luminex multifactor analysis.The expressions of these cytokines in liver macrophages(L-Mψ)and other non-parenchymal cells of Sham and Spx mice were analyzed by Real-time quantitative PCR(RT-qPCR)and flow cytometry.Macrophage cell line RAW264.7 or bone marrow-derived macrophages(BMDMs)were treated with liver homogenates from the Sham and Spx groups.Then the differently treated RAW264.7 cells were analyzed for mRNA expressions of cytokines and glutamine metabolism-related molecules by RT-qPCR,or transwell co-cultured with hepatic stellate cell line JS1.After co-culture,the survival and extracellular matrix expression of JS1 cells were analyzed.For comparison,Student's t test(between two groups)or one-way analysis of variance(among multiple groups)were used.Results Compared with normal control group,the concentrations of IL-1β,IL-13,TGF-β and TNF-α in the L-Homo of model group were significantly increased and showed higher levels in Sham group than in Spx group.Moreover,the hepatic macrophages were indicated as the major source of these cytokines.Consistently,macrophages treated with liver homogenate of Sham mice had increased expressions of IL-1β,TGF-β and TNF-α and glutaminase(GLS).After co-culture with macrophages treated with liver homogenate of Sham group rather than Spx group,JS1 expressed higher expressions of α-SMA and collagens.Conclusion The spleen is involved in regulating the secretion of cytokines by hepatic macrophages and enhancing their ability to activate hepatic stellate cells.
