OBJECTIVE To mine and analyze adverse event signals associated with inebilizumab， and to provide reference for safe and rational clinical use. METHODS Reports of adverse event related to inebilizumab were collected from the FDA adverse event reporting system （FAERS） database， from Q2 2020 to Q4 2024. Adverse events were standardized and categorized according to the preferred term （PT） and system organ class （SOC） of the Medical Dictionary for Regulatory Activities （MedDRA） version 26.0. Signals were mined using the reporting odds ratio （ROR） method and the Bayesian confidence propagation neural network （BCPNN） method. RESULTS A total of 783 adverse event reports with inebilizumab as the primary suspected drug were identified， involving 297 patients. Most reports originated from the United States and Japan， with physicians being the primary reporters. Female patients outnumbered males， and the most common age group was 45-64 years. Using the ROR method and BCPNN method， a total of 29 valid adverse event signals were detected， involving 12 SOCs and comprising 225 adverse event reports. The five most frequently reported PTs were headache， nausea， fatigue， infectious pneumonia and arthralgia. The five PTs with the strongest signal intensity were： B-cell recovery， decreased blood immunoglobulin G， spinal compression fracture， COVID-19 and acute respiratory distress syndrome. Among the 29 valid signals for adverse event， 19 were not documented in the drug package inserts， involving 10 SOCs and comprising 107 adverse event reports. These encompassed nervous system disorders， general disorders and administration site conditions， eye disorders， among others. CONCLUSIONS Inebilizumab treatment not only causes adverse events documented in the product information， such as infections， immunoglobulin reduction and infusion-related reactions but also leads to potential signals， including B-cell recovery， spinal compression fracture. When using this drug in clinical practice， the patient’s risk of infection and baseline immune status should be assessed， relevant indicators should be closely monitored， and targeted preventive measures should be considered when necessary.

Diabetic nephropathy （DKD）， as a common microvascular complication of diabetes mellitus （DM）， is a major cause of end-stage renal disease （ESRD）. Its clinical manifestations include increased urinary protein excretion， thickening of the glomerular basement membrane， and renal tubulointerstitial fibrosis. The pathogenesis of DKD is complex and involves multiple factors， including disordered glucose metabolism， hemodynamic alterations， and oxidative stress. Although modern medical approaches can alleviate certain symptoms， they still have limitations such as insufficient therapeutic targeting and prominent adverse effects. The transforming growth factor-β/Smad （TGF-β/Smad） signaling pathway is not only a tissue fibrosis pathway that has attracted considerable attention in recent years， but also regulates multiple protein molecules， including the glomerular podocyte slit diaphragm protein Podocin， interleukin-1β （IL-1β）， and superoxide dismutase （SOD）， thereby participating in various pathological processes and ultimately mediating renal injury. Flavonoid compounds， owing to their sustained pharmacological effects， broad spectrum of action， and high safety profile， have become ideal candidates for targeted therapy research in DKD. Existing studies have shown that these compounds can exert inhibitory effects on renal fibrosis， alleviate inflammatory responses， protect podocytes， and reduce oxidative stress by regulating the interactions between the TGF-β/Smad signaling pathway and the aforementioned protein molecules， thereby maintaining renal structure and function， reducing proteinuria， and significantly improving DKD lesions. This review briefly outlines the composition and functions of the TGF-β/Smad signaling pathway， elucidates the mechanisms by which this pathway regulates DKD， and focuses on summarizing major studies from the past decade on flavonoid-based interventions in DKD through targeted inhibition of the TGF-β/Smad signaling pathway. Furthermore， it discusses the considerable therapeutic potential of flavonoids in the treatment of this disease， aiming to provide a scientific basis for future clinical prevention and treatment of DKD and to promote the development of targeted drugs.

Abstract To promote the mental health of college students and build campus based psychological support system, the study explains that current applications of digital health interventions (DHIs) include independent forms based on a single technology or platform, as well as integrated forms that combine multiple digital technologies with traditional mental health services. These interventions have positive effects on alleviating negative emotions among college students, enhancing psychological resilience, improving quality of life, and ameliorating academic performance. However, differences still exist in the stability of intervention effects. Future development requires continuous improvement in institutional construction, ethical governance and capacity building.

Purpose To evaluate the diagnostic accuracy of low-iodine contrast subtraction CT pulmonary angiography(CTPA)combined with iodine maps for acute pulmonary embolism(APE),with a focus on detecting subsegmental emboli.Materials and Methods A retrospective analysis included 48 patients with suspected APE who underwent both pulmonary ventilation/perfusion SPECT/CT and low-iodine subtraction CTPA within one week in Beijing Hospital from September 1,2021 to September 1,2024.Using SPECT/CT as the reference standard,the diagnostic performance of subtraction CTPA with iodine maps was assessed.A retrospective review was performed to identify potential causes of false-positive and false-negative results.Results Subtraction CTPA with iodine maps demonstrated high diagnostic accuracy at the segmental and subsegmental pulmonary artery levels,with a sensitivity of 0.917 and specificity of 0.991.At the segmental level,the detection rate was 100%,while at the subsegmental level,it was 66.7%.The method showed consistently high diagnostic performance(83.3%-100%)across different clinical risk stratifications of APE.Retrospective review identified explicable causes for 85.7%(6/7)of false-positive and 33.3%(2/6)of false-negative cases.Conclusion Low-iodine subtraction CTPA combined with iodine maps exhibits robust diagnostic efficacy for APE.Accurate recognition of characteristic perfusion defects on iodine maps may further enhance diagnostic precision.

Objective:To describe the epidemiological characteristics of 22 common respiratory patho-gens in patients with pneumonia in Yinzhou,Ningbo,from January 1,2015 to December 21,2024.Methods:The test data of 22 common respiratory pathogens in patients diagnosed with pneumonia or lung infection in the Yinzhou Regional Health Information Platform from January 1,2015 to December 21,2024 were collected.The positive cases,positive rates,and positive proportions were calculated.The epidemiological characteristics were described by the year,sex,age group,season,and coronavirus disease 2019(COVID-19)pandemic period.Results:A total of 77 531 pneumonia patients were included,with 492 696 respiratory pathogen tests performed.The number of respiratory pathogen tests and positive cases of pneumonia patients in Yinzhou showed an upward trend.In the study,34.63％of the pneumo-nia patients tested positive for at least one pathogen,and the pathogen non-detection rate decreased from 79.44％in 2015 to 58.38％in 2024.The overall pathogen positive rate was 9.12％,which decreased during the COVID-19 pandemic and had not returned to the historical level after the COVID-19 pande-mic.The positive rate was highest in children aged 6-17 years(13.99％),and lowest in the elderly over 60 years(4.16％).The top 3 highest number of positive cases was Mycoplasma pneumoniae,influenza A virus,and influenza B virus;the top 3 highest positive rates of pathogen tests were Mycoplasma pneu-moniae(25.26％),rhinovirus(12.02％),and Bordetella pertussis(11.66％).The pathogen spectrum proportion in men was similar to that in women,only showing a higher ratio of Mycobacterium tuberculosis and a slightly lower ratio of Mycoplasma pneumoniae(P＜0.001).Mycoplasma pneumoniae,respiratory syncytial virus,and rhinovirus infections were more common in children,while influenza virus,Mycobac-terium tuberculosis,and Streptococcus pyogenes infections were more common in adults and the elderly(P＜0.001).Influenza virus and human metapneumovirus infections were more common in winter,rhi-novirus and Bordetella pertussis infections were more common in spring,and Mycoplasma pneumoniae in-fections were relatively more common in fall(P＜0.001).After the COVID-19 pandemic,the propor-tions of rhinovirus,respiratory syncytial virus,and human metapneumovirus infections in the pneumonia patients increased signi-ficantly,reaching 7.53％,4.26％,and 2.25％,respectively,while the propor-tions of influenza B virus and Mycobacterium tuberculosis infections decreased to 4.14％and 2.80％,re-spectively(P＜0.001).Conclusion:In the past decade,the scale of respiratory pathogen infection in the pneumonia population in Yinzhou had expanded significantly,and there were differences in distribu-tion by the year,gender,age group,and season.The respiratory pathogen spectrum in pneumonia pa-tients after the COVID-19 pandemic had a trend of diversification.

Objective To analyze the preferences of elderly cancer patients for internet hospital diagnosis and treatment services,providing a reference for the sustainable development of internet hospitals.Methods This study was based on the method of discrete choice experiments.By combining literature review and expert consultation,10 relevant attributes affecting the choice of internet hospitals by elderly cancer patients were determined.Through KANO questionnaires,6 key attributes were se-lected to form the final DCE questionnaire,consisting of 11 choice sets and 1"quality control"set.Using the convenience sam-pling method,elderly cancer patients visiting a certain tertiary hospital in Tianjin were selected to collect 318 valid question-naires.The obtained data were analyzed using mixed Logit regression.Results Patients visiting a certain specialized cancer hos-pital in Tianjin tend to prefer hospitals with a grade of Grade Ⅲ-A(β=0.661 6,P＜0.05)and those offering out-of-hospital rehabilitation guidance for cancer patients(β=0.559 9,P＜0.05).The page operation process(β=0.352 2,P＜0.05)and the accessibility mode for the elderly(β=0.357 5,P＜0.05)are the attributes with lower attention.In the subgroup analysis,for patients of different genders and different family incomes,hospital grade and out-of-hospital rehabilitation guidance for cancer patients remain the most influential factors,but male patients pay more attention to the page operation process(β=0.378 3,P＜0.05)and the accessibility mode for the elderly(β=0.373 7,P＜0.05),while female patients pay more attention to the cover-age of medical insurance reimbursement(β=0.435 9,P＜0.05),which has a greater impact than that of male patients(β=0.394 7,P＜0.05);patients with a monthly per capita income of less than 5 000 yuan pay more attention to the coverage of medical insurance reimbursement(β=0.423 0,P＜0.05)and the self-appointment check function(β=0.467 0,P＜0.05);while patients with a monthly per capita income of more than 5 000 yuan pay more attention to the page operation process(β=0.364 7,P＜0.05)and the accessibility mode for the elderly(β=0.359 1,P＜0.05).Conclusion Hospitals should en-hance elderly patients' awareness and trust in internet hospitals by providing comprehensive health education and support,simpli-fying operational processes,strengthening age-friendly design,and highlighting medical insurance coverage to address the diverse needs across genders and income levels.

Objective:To explore the latent categories of mental health problems in patients with systemic lu-pus erythematosus(SLE)through latent class analysis,and to analyze the association between these mental health categories and both disease activity and fatigue in patients.Methods:Totally 147 patients with SLE were recruited from February 2022,to December 2023,at the department of Rheumatology,Qilu Hospital of Shandong Universi-ty.Latent class analysis was utilized to identify the latent categories of mental health problems.Multivariate linear regression was employed to analyze the association between these mental health categories and both disease activity and fatigue in patients with SLE.Results:Latent class analysis of four types of mental health problems in patients with SLE revealed two latent categories:a high mental health problems group(n=60)and a low mental health problems group(n=87).Compared to the low mental health problems group,the high mental health problems group showed a positive association with patient self-assessed disease activity(β=0.22)and fatigue(β=0.27).Conclusion:Mental health problems are common among patients with SLE and occur concurrently.Comprehensive management strategies should be selected when implementing psychological interventions.

Purpose To investigate the correlation between tumor budding in penile squamous cell carcinoma(SCC)and its clinicopathological features.Methods Clinical data and pathological slides from 69 cases of penile SCC were collected.Tumor budding was examined microscopically,and statistical analyses were performed to assess the relationship between tumor budding and various clinicopathological features.Results Among the 69 cases of pe-nile SCC,41 cases exhibited low-grade tumor budding and 28 cases displayed high-grade tumor budding.Tumor bud-ding was significantly correlated with tumor size,urethral invasion,invasion of the urethral corpus spongiosum,inva-sion of the penile corpus cavernosum,tumor necrosis,nerve invasion,vascular tumor thrombus,and pathological T stage(all P＜0.05).In contrast,no significant association was found between tumor budding and HPV-related versus non-HPV-related penile SCC(P＞0.05).Log-rank survival analysis indicated that patients with high-grade tumor bud-ding had a significantly lower survival rate compared to those with low-grade tumor budding(P＜0.05).Conclusion Tumor budding is a distinct pathological feature of penile SCC,and high-grade tumor budding is associated with a more aggressive biological behavior.

Microgravity-induced cardiac remodeling presents a substantial challenge that constrains the advancements in the international space industry,which mainly manifests as alterations in the morphology,structure,and function of the heart.This paper analyzed the core pathogenesis and treatment of microgravity-induced cardiac remodeling based on the theory of"yang transforming qi and yin forming shape"in Huangdi Neijing."Yang transforming qi"reflects the changes in cardiac function,whereas"yin forming shape"reflects the changes in cardiac morphology and structure.Based on the basic and clinical research of space cardiac dysfunctions,the core pathogenesis of microgravity-induced cardiac remodeling is the insufficiency of"yang transforming qi",accompanied by yin excess and yang deficiency due to excessive"yin forming shape"in the early stage,which evolves into deficiency of both yin and yang in the late stage.Thus,this paper specifically refined the treatment methods and corresponding formulas,including warming viscera yang to transform qi,draining yin blood to restore yang qi,and consolidating yin and yang to nourish primal energy.These insights provide systematic theoretical support and conceptual inspiration for the traditional Chinese medicine treatment of microgravity-induced cardiac remodeling.
