文摘Diabetic retinopathy(DR)is a leading cause of vision loss among working-age populations,with early screening significantly reducing the risk of blindness.However,resource-limited regions often face challenges in DR screening due to a shortage of ophthalmologists.This study reports the implementation and outcomes of the Chinese local standard DB52/T 1726-2023,Regulations for the application of diabetic retinopathy screening artificial intelligence,in Cambodian healthcare institutions.A pilot DR screening program with independent operational capability is established by providing a non-mydriatic fundus camera and deploying a localized diabetic retinopathy artificial intelligence(DR-AI)screening platform at the Cambodia-Kingdom Friendship Hospital in Phnom Penh,along with comprehensive training.From January to August 2025,a total of 565 patients with type 2 diabetes were screened,yielding a DR detection rate of 26.0%(147 cases).Research findings demonstrate that applying mature Chinese DR-AI screening standards and technological solutions through international collaboration in regions with a scarcity of ophthalmic professionals is both feasible and effective.This project serves as a reference for promoting DR-AI in resource-constrained countries and regions,highlighting its significant potential to leverage AI in addressing the global burden of chronic diseases and advancing the modernization of health systems.

文摘With the rapid development of image-generative AI (artificial intelligence) technology, its application in undergraduate Landscape Architecture education has demonstrated significant potential. Based on this, the present study explores the implications of integrating image-generative AI into Landscape Architecture courses from three perspectives: stimulating students creative design potential, expanding approaches to form and concept generation, and enhancing the visualization of spatial scenes. Furthermore, it discusses application strategies from three dimensions: AI-assisted conceptual generation, human-machine collaboration for design refinement, and optimization of scheme presentation and evaluation. This paper aims to provide relevant educators with insights and references.

文摘This article reviews the research advances in traditional Chinese medicine rhubarb and its compound formulations in the treatment of sepsis,with particular emphasis on elucidating their mechanisms of action and clinical application value.Research has demonstrated that rhubarb and its compound formulations exert therapeutic effects via multiple targets and mechanisms,including anti-inflammatory actions,protection of the intestinal barrier,modulation of immune balance,inhibition of oxidative stress,and regulation of associated signaling pathways.Clinically,rhubarb has shown distinct advantages in enhancing gastrointestinal function,mitigating systemic inflammatory responses,and reducing mortality rates among patients with sepsis.These findings provide a foundational reference for the integrated prevention and treatment of sepsis through the combined use of traditional Chinese and Western medicine.

文摘ABSTRACT Melt electrowriting(MEW)enables the precise deposition of polymeric fibers at micro-/nanoscale,allowing for the fabrication of 3D biomimetic scaffolds.By incorporating stimuli-responsive polymers and/or functional fillers,MEW-based 4D printing creates scaffolds capable of undergoing controlled,reversible shape transformations in response to external stimuli over time.These dynamic 4D scaffolds can be tailored for minimally invasive delivery,remote actuation,and real-time responsiveness to physiological environments,making them highly relevant for biomedical applications.This review systematically elucidates the principles of MEW-based 4D printing,including material considerations,actuation methods,and structure design strategies,along with shape programming and morphing mechanisms.The versatility of MEW for rational fabrication of biomimetic scaffolds is firstly introduced.Subsequently,the critical elements underpinning MEW-based 4D printing process are overviewed,including an analysis of stimuli-responsive materials compatible with MEW,an evaluation of applicable external stimuli,and a discussion on the advancements in design strategies for 4D scaffolds.Recent progress of MEW 4D scaffolds for applications in tissue engineering,biomedical implants,and drug delivery systems are highlighted.Finally,key challenges and perspectives toward material innovation,fabrication optimization,and actuation control are discussed.This review aims to provide valuable insights for design and creation of multifunctional biomimetic dynamic scaffolds by MEW-based 4D printing.
