Acute liver injury (ALI) serves as a critical precursor and major etiological factor in the progression and ultimate manifestation of various hepatic disorders. The prevention and treatment of ALI is still a serious global challenge. Given the limited therapeutic options for ALI, exploring novel targeted therapeutic agents becomes imperative. The potential therapeutic efficacy of inhibiting RIPK2 is highlighted, as it may provide significant benefits by attenuating the MAPK pathway and NF-κB signaling. Herein, we propose a CMD-OPT model, a two-stage molecular optimization tool for the rapid discovery of RIPK2 inhibitors with optimal properties. Compound RP20, which targets the ATP binding site, demonstrated excellent kinase specificity, ideal oral pharmacokinetics, and superior therapeutic effects in a model of APAP-induced ALI, positioning RP20 as a promising preclinical candidate. This marks the first application of RIPK2 inhibitors in ALI treatment, opening a novel therapeutic pathway for clinical applications. These results highlight the efficacy of the CMD-OPT model in producing lead compounds from known active molecules, showcasing its significant potential in drug discovery.

As an independent first-level discipline,an appropriate classification of nursing science is significant.In China,each nursing degree-granting institution has developed its own secondary-level discipline directions based on its research characteristics and strengths,with varying names and research scopes.Furthermore,there is no unified global classification system.This paper,based on the characteristics of nursing as a discipline and combined with China's discipline classification principles,used literature analysis,comprehensive classification,philosophical reflection,logical reasoning,and expert consultation methods to explore the connotation of nursing,its unique research objects and scope,and to construct a secondary-level discipline classification system for nursing science that is suitable for China's national conditions.The paper also discussed the challenges faced by the nursing discipline and its future development directions,providing theoretical and practical guidance for the development of the nursing discipline.

Nine novel compounds, comprising seven tetrahydroanthraquinones (auxarthrolones A-G, 1-7), a γ-butenolide glycoside (malfilamentoside E, 26), and a γ-butenolide (auxarthrolide A, 27), together with eighteen known compounds (8-25) were isolated from rice-based solid culture of Auxarthron umbrinum (A. umbrinum) DSM3193 using the one strain many compounds (OSMAC) approach. The structural elucidation of these compounds was accomplished through nuclear magnetic resonance (NMR), mass spectrometry (MS), and NMR calculation combined with DP4+ analysis or MAEΔΔδ parameter, while the absolute configurations of new compounds were established through single-crystal X-ray diffraction, electronic circular dichroism (ECD) spectroscopic data analysis and/or chemical derivatization. Austrocortilutein (10) and auxarthrol H (14) demonstrated moderate cytotoxicity against U87 and U251 [half maximal inhibitory concentration (IC₅₀) 3.5-12.1 μmol·L^-1]. Additionally, auxarthrolone A (1), auxarthrol H (14), eupolyphagin B (15), and 7-hydroxy-2-(2-hydroxypropyl)-5-methylchromone (17) exhibited torsional effects on fibroblast proliferation challenges induced by oleic acid, thus demonstrating fibroblast proliferation-promoting activity.

Objective To analyze the disability level and long-term care needs assessment policies issued by 49 pilot cities in China's long-term care insurance system,providing insights for further improvement of the system.Methods Policy documents related to long-term care insurance,published between June 2016 and December 2024 on official platforms of local governments,the Ministry of Human Resources and Social Security,the National Healthcare Security Administration,and the National Public Service Platform for Standards Information,were retrieved.A comparative analysis was used to summarize and compare the content of these policy texts.Results Currently,there are 49 pilot cities implementing the long-term care insurance system in China.47 cities have issued disability level assessment standards,with 38 cities adopting the trial standards issued by the National Healthcare Security Administration.In 42 pilot cities,the disability level assessment includes indicators such as activities of daily living,cognitive function,and sensory and communication abilities.22 cities have issued policies related to care needs assessment.In most cities,the care needs assessment partially or fully includes indicators from the disability level assessment.Conclusion There is no national uniformity in disability level assessment standards,and the care needs assessment framework needs further improvement.It is recommended to standardize disability level assessment criteria,clearly delineate the boundaries and content of disability level and care needs assessments,and enhance the development of the care needs assessment system.

On the occasion of the 30th anniversary of Chinese Journal of Modern Nursing, this paper systematically elaborates the development of geriatric nursing as a core discipline in addressing the challenges of aging, from its inception and systematization to innovative development, and analyzes its challenges and prospects. Against the backdrop of China's large aging population and accelerating aging trend, geriatric nursing aims to meet the multi-level health needs of older adults. It has gradually expanded from early focus on disease-centered care to holistic health maintenance, functional promotion, and quality of life improvement for older adults, with the discipline's scope and depth continuously evolving. The discipline development can be divided into three stages: the foundation stage, defined by the initiation of national policies and the establishment of educational systems and teaching materials; the system-building stage, characterized by clearer disciplinary positioning, refined curriculum system, diversified clinical practices, and a robust talent development mechanism; and the innovative development stage, when, driven by policies, technology, and interdisciplinary collaboration, high quality and diversification are emerging. However, geriatric nursing still faces challenges such as insufficient coordination in top-level design, an incomplete theoretical framework, an imbalance between supply and demand for services, and uneven distribution of educational resources. In the future, through policy system optimization, smart health and wellness technology, multidisciplinary integration, education system reform, and deepening scientific research and international cooperation, a modern geriatric nursing discipline system with Chinese characteristics will be established to support healthy aging and the healthy China strategy.

Helicobacter pylori ( H. pylori) is classified as Class I carcinogen in the World Health Organization. It was reported that approximately 90% of gastric cancer cases were associated with H. pylori infection. The eradication of H.plyori can effectively reduce the recurrence rate of peptic ulcers and the incidence of gastric adenocarcinoma. With the escalating antibiotic resistance, the eradication is facing significant challenges. The Maastricht VI/Florence consensus recommends routine antibiotics susceptibility testing to improve the eradication rate of H.plyori. The traditional bacterial culture and identification method require high compliance, laboratory conditions and operative technical, which is difficult to be routinely executed in clinical practice. Molecular biological detection methods have emerged as a proficient tool to identify antibiotic resistance with high efficiency, convenience, accuracy and repeatability. This review summarizes the molecular biological detection strategies for assessing H.plyori resistance, including advantages, limitations, opportunities and challenges.

This paper conducts a systematic literature review to analyze and summarize the current status, admission standards, practical scope, competency requirements, and talent cultivation of public health nursing teams both domestically and internationally, in order to provide reference for the development of public health nursing in China and assist in the improvement of the public health talent team.
