Echinococcosis is a neglected zoonotic parasitic disease across the world, which imposes a substantial burden on human health and socioeconomic development in endemic areas. From a One Health perspective, this review systematically summarizes the legal framework, scheme, integrated interventions, control achievements, and challenges in the national echinococcosis control programme of China. An integrated strategy centered on control of the source of Echinococcus infections has been implemented for echinococcosis control in China, and cross-sectoral and cross-regional multidisciplinary coordination mechanisms have been progressively established, resulting in remarkable achievements gained in human health, animal health, and integrated environmental management. The endemicity of echinococcosis remarkably reduced in China in 2023 as compared to results from the national echinococcosis epidemiological survey in China between 2012 and 2016 (baseline), with an 82.14% reduction in human prevalence, an 80.00% reduction in detection of echinococcosis among children, a reduction of prevalent echinococcosis patients to 25 400 cases, a 36.96% reduction in the number of dogs, an 88.24% reduction in the prevalence of Echinococcus infections in dogs, a 67.00% reduction in the number of stray dogs, an 80.77% reduction in the prevalence of echinococcosis in live-stock, and a 69.23% reduction in the prevalence of Echinococcus infections in rodents. Nevertheless, an estimated 14 600 canines were found to have Echinococcus infections in endemic areas across China in 2023, and the prevalence of Echinococcus infections increased by 241.03% in wild canines in 2023 relative to in 2021, which underscores the persistent threat to echinococcosis transmission. Future efforts are required to strengthen the One Health governance system, increase the financial investment, foster innovations in integrated control technologies, enhance cross-sectoral collaboration, and improve the capacity building at the grassroots level to advance the achievement of the national target of basically controlling echinococcosis in all endemic counties in China by 2030, thereby facilitating the process towards echinococcosis control and elimination.

With the rapid advancement of medical technology and the increasing complexity of clinical environments, competence in clinical ethical decision-making has become an indispensable core competency for exemplary physicians. However, traditional medical ethics education has long been confronted with the persistent challenges of theory-practice dissociation and the disconnect between pedagogical settings and clinical realities. Thus, how to construct a "Clinical Ethics" curriculum that aligns with the objectives of training high-caliber medical professionals has emerged as a critical and challenging issue in current medical education reform. To effectively address this challenge, the Office of Education at Peking University Third Hospital, since 2021, has assembled a multidisciplinary "Clinical Ethics" teaching and management team comprising faculty from Peking University School of Humanities and key clinical specialists from the hospital. In 2022, the "Clinical Ethics" elective course was formally launched for fourth-year students in the eight-year MD program who had completed coursework in "Medical Ethics" and organ-system-based curricula, with the aim of exploring and operationalizing a pre-clinical ethics education model tailored for senior medical students. The course employs a modular instructional design encompassing "theoretical review-case-based deliberation-clinical workshop", which effectively facilitates the deep integration of medical humanities with clinical practice.Following four years of iterative refinement through the "plan-act-observe-reflect" cycle, the course has demonstrated positive outcomes in enhancing students' ethical awareness and decision-making capabilities, and has preliminarily established a sustainable collaborative mechanism among the multidisciplinary faculty team. This article systematically delineates the course development background, pedagogical model and methodological innovations, and the multidisciplinary collaborative framework, alongside reflections and summaries based on implementation outcomes, with the intent of providing references for the future development of "Clinical Ethics" curricula.

AIM: To address the problem of cognitive overload and deviation from core teaching objectives caused by information redundancy in traditional case-based teaching in ophthalmology, Occam's Razor principle was innovatively applied to construct a set of streamlined case-based teaching resources, and their effectiveness was subsequently validated.METHODS:This was a prospective randomized controlled trial. Intern students from the 2019 and 2020 cohorts of the five-year clinical medicine program who completed their ophthalmology clerkship at the Department of Ophthalmology, Tangdu Hospital, Air Force Medical University between June 2023 and May 2025 were enrolled. By using a random number table, they were randomly assigned to an experimental group and a control group. Cases refined by Occam's Razor principle(removing irrelevant information and focusing on core principles, clinical reasoning, and the diagnostic and therapeutic workflow)were adopted for the experimental group, whereas the original complete cases were used for the control group. Teaching effectiveness was assessed through knowledge tests, classroom performance evaluation, teaching case assessment, and student satisfaction.RESULTS:Totally 120 students were included in this study and all of them completed the research. There were 60 students in the experimental group(43 males and 17 females, mean age 21.72±0.76 y)and 60 students in control group(41 males and 19 females, mean age 21.68±0.57 y)(all P>0.05). The score rates on the ocular trauma section and on the case analysis questions were significantly higher in the experimental group than in the control group(83.21%±7.96% vs 74.25%±11.01%; 84.31%±8.08% vs 67.62%±11.63%; both P<0.001). Teacher evaluations indicated that the experimental group achieved better scores than the control group in aspects such as identification of key case points and logical clinical reasoning(all P<0.001). A significantly lower cognitive load score was observed in the experimental group, whereas higher scores were obtained for clarity of case structure, thought-provoking quality, and teaching value(all P<0.001). The teaching satisfaction rate reached 95% in the experimental group, which was higher than the 83% observed in the control group(P<0.05).CONCLUSION: Refined cases guided by Occam's Razor principle can significantly reduce cognitive load, enhance medical students' efficiency in mastering core diagnostic and therapeutic principles, improve the precision of clinical reasoning, and strengthen execution of clinical procedures, thereby providing an innovative pathway for clinical teaching reform.

AIM: To investigate the potential inhibitory effect of pterostilbene on the endothelial-to-mesenchymal transition(EndMT)induced by high glucose conditions in human retinal microvascular endothelial cells(HRMECs).METHODS: The optimal concentration of pterostilbene for treating HRMECs was determined using the CCK-8 assay, with 12.5 and 25 μmol/L concentrations selected for subsequent experiments. Four experimental groups were established: control group, high glucose group, high glucose combined with 12.5 μmol/L pterostilbene treatment group, and high glucose combined with 25 μmol/L pterostilbene treatment group. The expression levels of HDAC7 and EndMT-associated markers were detected via Western blot analysis. Cell migration ability was assessed using Transwell migration assays and scratch wound healing tests, while vasculogenic capability was evaluated through tube formation assays.RESULTS: The CCK-8 assay revealed that pterostilbene at a concentration of 22.07 μmol/L inhibited 50% of cell viability in HRMECs. Western blot analysis demonstrated that compared with the control group, the expression levels of HDAC7, ZEB1, Vimentin, and Snail were significantly upregulated in HRMECs cultured in high glucose(all P<0.01), while the expressions of VE-cadherin and CD31 were significantly reduced(all P<0.01). Compared to the high glucose group, the treatment with 12.5 and 25 μmol/L pterostilbene significantly reduced the expression of HDAC7, ZEB1, Vimentin, and Snail under high glucose conditions(all P<0.01). Notably, 25 μmol/L pterostilbene enhanced the expression of VE-cadherin and CD31(all P<0.01). Scratch wound healing tests revealed that HRMECs treated with high glucose exhibited a significantly increased cell migration rate compared to the control group(P<0.05), while the application of 25 μmol/L pterostilbene significantly suppressed HRMECs migration under high glucose conditions(P<0.01). Transwell migration assays demonstrated that the cell migration rate in the high glucose group was significantly higher than that in the control group(P<0.01), with cell migration rate markedly reduced following treatment with both of 12.5 and 25 μmol/L pterostilbene(all P<0.01). The tube formation assay revealed that the ability of HRMECs to form tubular structures was significantly enhanced under high glucose conditions(P<0.01), and both 12.5 and 25 μmol/L of pterostilbene effectively inhibited this effect(all P<0.01).CONCLUSION: Pterostilbene can inhibit HDAC7 expression, suppress EndMT-mediated migration of HRMECs, and impair tube formation under high-glucose conditions.
