OBJECTIVE To assess the bleeding risk signals associated with the concomitant use of direct oral anticoagulants (DOACs) and triazole antifungals, and to provide pharmacovigilance evidence for the safety evaluation and monitoring of combined clinical use. METHODS Adverse event reports involving the concomitant use of DOACs and triazole antifungals were extracted from the US FDA Adverse Event Reporting System (FAERS) from the first quarter of 2004 to the third quarter of 2025. Nine bleeding-related preferred terms (PTs) were selected. The Ω shrinkage measure, additive model, multiplicative model, and combined risk ratio method were employed to detect drug-drug interaction signals. The strength of positive signals was further analyzed based on the Ω shrinkage measure. RESULTS A total of 790 adverse event reports involving the concomitant use of DOACs and triazole antifungals were included, among which 229 reports involved nine bleeding-related PTs. A total of 13 signals were consistently identified as posit ive by all four methods. These signals involved six drug combinations: apixaban-fluconazole, apixaban-posaconazole, rivaroxaban-itraconazole, dabigatran etexilate-fluconazole, apixaban-voriconazole, and dabigatran etexilate-itraconazole. The Ω shrinkage measure showed that the apixaban-posaconazole combination exhibited stronger signals for bleeding ( Ω =2.73, Ω 025 =2.05) and hemoptysis ( Ω =2.17, Ω 025 =0.83); the apixaban-fluconazole combination exhibited stronger signals for hematoma ( Ω =2.30, Ω 025 =1.47) and hematuria ( Ω =1.71, Ω 025 =0.74); the rivaroxaban-itraconazole combination exhibited stronger signals for epistaxis ( Ω =2.01, Ω 025 =0.90) and hematoma ( Ω =1.93, Ω 025 =0.42); no positive Ω signals were observed for intracranial hemorrhage or upper gastrointestinal hemorrhage. CONCLUSION S This study suggests that the concomitant use of DOACs and triazole antifungals may increase the risk of bleeding-related events, with differences in signal strength and signal distribution across various drug combinations. In clinical practice, particular attention should be paid to the concomitant use of apixaban or rivaroxaban with strong cytochrome P450 3A4 or P-glycoprotein inhibitors such as posaconazole and itraconazole. For other DOAC-triazole antifungal combinations, close monitoring for bleeding-related manifestations and timely adjustment of anticoagulation or antifungal regimens are also warranted.

Retinopathy of prematurity(ROP)is a leading cause of childhood blindness, with extremely preterm and very-low-birth-weight infants now constituting the main high-risk group. ROP progresses in two stages: early retinal microvascular degeneration and progressive vascular arrest, followed by abnormal neovascularization in the avascular area. Early oxidative and nitrosative stress—amplified by oxygen fluctuations and immature antioxidant defenses—drives the two-phase pathogenesis via hypoxia-inducible factor/vascular endothelial growth factor(HIF/VEGF), NOX/STAT3, and nuclear factor erythroid 2 related factor 2(Nrf2)-antioxidant response element(ARE)pathways, mediating apoptosis of endothelial cells, damage to barrier and pathological angiogenesis. This review systematically analyzes different oxygen-induced retinopathy(OIR)models, elucidates key signaling pathways including Notch, Wnt in physiological and pathological vascularization, with particular emphasis on the biphasic effects of Nrf2 and the differential roles of NOX signaling between phases. We also discuss the limitations of anti-VEGF therapy and oxygen management principles. Reactive oxygen species(ROS)play context-dependent roles across vaso-obliteration and neovascularization phases. Based on mechanistic insights, we propose future directions including combined/sequential interventions, ferroptosis and lipid peroxidation targeting, nano-delivery systems for enhanced bioavailability, and perinatal safety assessment strategies, aiming to provide translatable mechanistic basis for reducing pathological neovascularization while promoting physiological vascular development.

Objective:To explore the relationship of metacognitive regulation, self-efficacy, and motivation regulation with learning engagement among medical students in military academies.Methods:A total of 439 students from the Air Force Medical University were selected by convenience sampling in March to April 2023. The Metacognitive Self-Regulation Scale, Self-Efficacy Scale, Learning Engagement Scale, and Motivation Regulation Questionnaire were adopted for investigation. SPSS 25.0 was used for Pearson correlation analysis, and the Process procedure for analysis and testing of mediating effects.Results:A total of 436 usable questionnaires were collected. Metacognitive regulation, self-efficacy, motivation regulation, and learning engagement were significantly positively correlated ( r>0.477, P<0.01). The mediating effect of self-efficacy and motivation regulation and the chain mediating effect of self-efficacy-motivation regulation were significant between metacognitive regulation and learning engagement, and the effect sizes were 0.449, 0.244, and 0.130, accounting for 44.37%, 24.11%, and 12.85% of the total effect, respectively. The proportion of the total indirect effect was 81.32%. Conclusions:The metacognitive regulation of medical students in military academies directly affects learning engagement, which is also indirectly affected through the independent mediating effect of self-efficacy and motivation regulation or the chain mediating effect of self-efficacy-motivation regulation.

Objective:To investigate the clinical features, imaging characteristics, surgical strategies, and therapeutic outcomes of otitis media complicated with inflammatory response of local meninges.Methods:A retrospective analysis was conducted on the clinical data of 8 patients with chronic suppurative otitis media complicated with inflammatory response of local meninges, treated by the Department of Otolaryngology, Head and Neck Surgery, PLA General Hospital from 2019 to 2023. Appropriate surgical strategies were selected based on the patient′s clinical manifestations, imaging characteristics, extent of lesions, and facial nerve function. Follow-up was performed postoperatively to assess the therapeutic outcomes.Results:Among the eight patients, there were six males and two females, with an average age of (55.9±12.6) years old. The primary clinical manifestations included otorrhea, hearing loss, facial paralysis, earache, headache, and fever. All patients had a history of chronic suppurative otitis media and tympanic membrane perforation, with varying degrees and types of hearing loss. Seven patients presented with peripheral facial palsy preoperatively, with the House-Brackmann (H-B) grading scale as follows: 4 cases (4/7) in grade Ⅳ, 1 case (1/7) in grade Ⅴ, and 2 cases (2/7) in grade Ⅵ. The mean duration of otorrhea and/or hearing loss was (24.68±12.18) years, while, the average duration of severe headache, aggravated otorrhea and facial paralysis was (2.73±3.92) months. Preoperative high-resolution CT scan of the temporal bone revealed soft tissue shadow in the middle ear and mastoid process, with partial defects in the mastoid cortex. Cranial MRI T1WI showed high signal in the meninges on the affected side, with contrast-enhanced MRI indicating localized meningeal thickening. Four patients (4/8) had diabetes mellitus, and 2 patients (2/8) had a history of middle ear/mastoid surgery. All patients underwent surgical treatment, including thorough removal of lesions, adequate drainage, and facial nerve decompression. Tympanoplasty and hearing reconstruction were performed when conditions permitted. Specifically, 5 patients underwent intact canal wall radical mastoidectomy with facial nerve decompression and tympanoplasty, 2 patients underwent canal wall down mastoidectomy with facial nerve exploration decompression, and 1 patient underwent modified radical mastoidectomy. Postoperatively, patients experienced significant relief and gradual disappearance of ear and head pain. The postoperative H-B grading scale of facial nerve function was as follows: 4 cases in grade Ⅰ (4/8, including 1 case without preoperatively facial palsy), 2 cases (2/8) in grade Ⅱ, and 2 cases (2/8) in grade Ⅲ. Postoperative cranial MRI showed a significant reduction in localized meningeal thickening on the affected side.Conclusions:Patients with long-term chronic suppurative otitis media and/or cholesteatoma who suddenly presented with headache, fever, aggravated otorrhea, and facial paralysis should be suspected of having inflammatory response of local meninges. High-resolution CT of temporal bone and cranial MRI provide crucial diagnostic information. Early surgical exploration and thorough lesion removal are effective treatment methods.

Objective:To explore the coordinated development status of the medical service supply-economy-society trinity systems in Zhejiang Common Prosperity Demonstration Zone,and to offer references for formulating policies conducive to the efficient and coordinated development of these three systems.Methods:Based on the panel data from 2013 to 2022,this research was conducted on the 11 prefectural-level cities in Zhejiang Province.Firstly,an evaluation index system for the three systems was established,and the entropy method was employed to determine the weights of each index and calculate the comprehensive evaluation index.Secondly,a triangular model was introduced to delineate the relative relationships among the three systems,and the coupling coordination degree model was utilized to disclose the coordination degree of the three systems.Finally,the spatial autocorrelation analysis method was applied to investigate the spatial autocorrelation of the coupling coordination degree of the three systems.Results:(1)On the whole,the development status of the three systems has improved over time,yet the comprehensive development level remains to be improved.(2)Overall,each prefectural-level city has transited from a medical service supply-society-dominated development to a balanced and coordinated development of the medical service supply-economy-society trinity systems.The coupling coordination degree of the three systems has risen from 0.468(on the verge of imbalance)in 2013 to 0.609(primary coordination)in 2022,presenting an upward trend in general.However,the coordination level remains to be improved and there exist imbalances among regions.(3)The coupling coordination degree of the three systems in Zhejiang Province exhibits a significant positive spatial correlation,and the spatial distribution characteristics are relatively stable. Conclusion:The coupling coordination degree of the medical service supply-economy-society trinity systems in Zhejiang Province awaits further enhancement. At the level of Zhejiang Province,favorable policy support should be provided,the layout of medical resources should be rationally planned,and high-quality economic and social development should be promoted. Each prefectural-level city should formulate strategies for medical service supply,economic,and social development in accordance with its own development level and local conditions,strengthen inter-city linkage and cooperation,and thereby elevate the coordinated development level of the three systems.

The endoplasmic reticulum is an important organelle responsible for the synthesis,folding and processing of proteins.When the endoplasmic reticulum protein folding ability is affect-ed,internal unfolded proteins or misfolded proteins accumulate in the endoplasmic reticulum accumulation,leading to endoplasmic reticulum structural dysfunction resulting in endoplasmic reticu-lum stress.Autophagy is the process by which cells selectively remove stress endoplasmic reticulum and error proteins.Under stress,the endoplasmic reticulum can maintain normal physiolog-ical functions through unfolded protein responses and autophagy.Postmenopausal osteoporosis is mainly due to an imbalance be-tween bone resorption by osteoclasts and bone formation by oste-oblasts.Endoplasmic reticulum stress and autophagy both modu-late bone cells status with consequences for bone homeostasis.This article provides a review of the progress of research on en-doplasmic reticulum stress and autophagy interaction in the path-ogenesis of postmenopausal osteoporosis.
