Animal experimentation constitutes a critical link between basic research and clinical application, making its research quality and translational efficiency paramount. Although considerable progress has been made in standardizing operational procedures and ethical guidelines, the standardization of outcome evaluation systems has significantly lagged, creating a key bottleneck that constrains the quality of biomedical research and evidence synthesis. This deficiency is manifested by pronounced heterogeneity in outcome selection across similar studies, incomplete methodological reporting, and disparate criteria for result interpretation, which severely impairs the comparability of findings and the evidence integration. To cope with this challenge, this paper systematically introduces a mature methodological tool from clinical research–the core outcome set (COS)–and explores its construction strategies and application potential in the field of animal experimentation. Given the extensive diversity of animal experiments, a pragmatic strategy of "focusing on key areas, implementing phased pilots, and promoting gradual expansion" should be adopted. This approach prioritizes the development of domain-specific COS for disease areas characterized by high research volume, urgent translational needs, and well-established animal models. A multi-source integration pathway for COS development is detailed, comprising systematic literature searches, methodological appraisals, and expert consensus, with the feasibility of leveraging artificial intelligence (AI) to enhance efficiency also being examined. The development and promotion of such COS are not intended to restrict scientific exploration; rather, they aim to establish a new, tiered evaluation paradigm consisting of "core outcomes" (mandatory), "recommended outcomes" (encouraged), and "exploratory outcomes" (optional). This framework is expected not only to enhance research quality through standardization and to adhere to the "3R" principles but also to accelerate the accumulation of high-quality evidence. This, in turn, provides a solid foundation for higher-level evidence synthesis, ultimately facilitating the effective translation of basic research findings into clinical practice and providing an essential methodological framework for scientific advancement in relevant disciplines.

BACKGROUND:Paraspinal muscle degeneration is one of the main causative factors of low back pain,and the changes in the paraspinal muscles are closely related to its occurrence and development.At present,clinical practitioners focus on the changes of paraspinal muscles in degenerative lumbar diseases to prevent and treat lumbar diseases,but ignore the connection and related mechanisms between lumbar intervertebral disc degeneration and paraspinal muscles.OBJECTIVE:To comprehensively summarize the interaction between paraspinal muscles and lumbar intervertebral discs,and to review the relationship and mechanisms between lumbar intervertebral disc degeneration and paraspinal muscles,in order to provide a reference for clinical prevention and treatment.METHODS:Chinese keywords"lumbar intervertebral disc,paraspinal muscle,multifidus muscle,low back pain,degeneration,imaging,magnetic resonance imaging"were used to search the relevant literature in Chinese databases such as CNKI,VIP,and WanFang.English keywords"lumbar disc,paraspinal muscle,multifidus muscle,low back pain,degeneration,imaging,MRI"were used to search the relevant literature in databases such as Medline,PubMed,and Web of Science.After preliminary screening of titles and abstracts,68 articles were finally selected for result analysis according to the inclusion and exclusion criteria.RESULTS AND CONCLUSION:(1)Researchers have used various methods to evaluate the degree of paraspinal muscle degeneration,and at the same time evaluated the degree of lumbar intervertebral disc degeneration according to the Pfirrmann grading system.It is found that clinical diagnosis and treatment should pay attention to gender differences,and the influence of factors such as obesity on the degeneration of intervertebral discs and muscles,in order to develop more individualized treatment plans.(2)There is a certain correlation between lumbar intervertebral disc degeneration and paraspinal muscle fat infiltration,but the research results are controversial.Most studies have found that fat infiltration of the paraspinal muscles(especially the multifidus muscle)is positively correlated with the degree of lumbar intervertebral disc degeneration.(3)It is currently believed that the three mechanisms of disuse atrophy,denervation,and inflammatory factors may interact with each other to jointly lead to structural and functional changes in the paraspinal muscles,which are closely related to the occurrence of lumbar intervertebral disc degeneration and low back pain.(4)Clinically,attention should be paid to the changes of the muscles at the level below the affected nerve root segment,which is helpful for the diagnosis and localization of lumbar radiculopathy.At the same time,inhibition of inflammatory factors may become a potential target for treatment.(5)Clinically,the first step is to correct nerve root compression through appropriate medication or surgery to control inflammatory reactions and nerve root pain,and then carry out targeted muscle rehabilitation training.If necessary,consider using new treatment methods such as interferential current electrical stimulation to improve the patient's symptoms and prognosis.

Objective:To investigate the clinical characteristics and risk factors associated with secondary systemic capillary leak syndrome (SSCLS) induced by acute organophosphorus pesticide poisoning (AOPP). The goal is to enhance clinical understanding of this complication and provide a theoretical foundation for the early identification of high-risk patients and the optimization of individualized treatment strategies.Methods:Clinical data were collected from patients admitted to the Emergency Department of Fuyang People’s Hospital Affiliated to Anhui Medical University between October 2019 and October 2024, who were diagnosed with acute dichlorvos poisoning. The clinical features of SSCLS were described, and patients were categorized into SSCLS and non-SSCLS groups. Binary multivariate logistic regression analysis was conducted on statistically significant indicators to identify independent risk factors for SSCLS. Receiver operating characteristic (ROC) curves were generated to evaluate the predictive value of these factors.Results:Among the 96 patients studied, 37 (38.5%) developed SSCLS. The median time from toxin ingestion to the onset of SSCLS was 3.0 (2.0-5.0) hours. In the 14 SSCLS survivors, the median duration of SSCLS was 50.0 (24-72) hours, whereas in the 23 non-survivors, it was 24.0 (12.0-35.0) hours. The mortality rate in the SSCLS group (62.16%, 23/37) was significantly higher than that in the non-SSCLS group (1.69%, 1/59) ( χ2=44.343, P<0.001). Blood toxin analysis detected trichlorfon components in 92 patients (95.83%). Binary multivariate logistic regression identified APACHE Ⅱ score and trichlorfon concentration (≥706.35 ng/mL) as independent risk factors for SSCLS ( P<0.05). ROC analysis revealed that the combination of these two factors had a higher predictive value ( P<0.05). Conclusions:In the diagnosis and treatment of acute dichlorvos (organophosphorus pesticide) poisoning, particular attention should be given to the combined toxic effects of dichlorvos and trichlorfon, which can lead to SSCLS. The onset and progression of SSCLS are rapid, and the condition is associated with a high mortality rate. Both APACHE Ⅱ scores and trichlorfon concentrations (≥706.35 ng/mL) are independent risk factors for the development of SSCLS, and their combined use enhances predictive accuracy. Early identification of high-risk patients and timely administration of individualized treatment are critical for reducing mortality rates. This revised abstract maintains the original meaning while improving clarity, flow, and readability. It ensures that the key points are presented in a structured and professional manner, suitable for a clinical audience.

Receptor-interacting protein kinase 1 (RIPK1) plays an essential role in regulating the necroptosis and apoptosis in cerebral ischemia-reperfusion (I/R) injury. However, the regulation of RIPK1 kinase activity after cerebral I/R injury remains largely unknown. In this study, we found the downregulation of protein arginine methyltransferase 1 (PRMT1) was induced by cerebral I/R injury, which negatively correlated with the activation of RIPK1. Mechanistically, we proved that PRMT1 directly interacted with RIPK1 and catalyzed its asymmetric dimethylarginine, which then blocked RIPK1 homodimerization and suppressed its kinase activity. Moreover, pharmacological inhibition or genetic ablation of PRMT1 aggravated I/R injury by promoting RIPK1-mediated necroptosis and apoptosis, while PRMT1 overexpression protected against I/R injury by suppressing RIPK1 activation. Our findings revealed the molecular regulation of RIPK1 activation and demonstrated PRMT1 would be a potential therapeutic target for the treatment of ischemic stroke.

Allergic rhinitis (AR), a globally prevalent immune-mediated inflammatory condition, is still an incurable disease. In the present study, we have validated the impact of the Kelch-like ECH associated protein 1 (Keap1)-related oxidative stress and inflammatory response in clinical AR patient peripheral blood and nasal swab samples, emphasizing the biological relevance of Keap1 and AR. Targeting Keap1 -nuclear factor erythroid 2-related factor 2 (Nrf2) related anti-oxidative stress may be effective for AR intervention. Drawing inspiration from the Keap1 homodimerization and the E3 ligase characteristics, we herein present a design of novel bivalent molecules for chemical knockdown of Keap1. For the first time, we characterized ternary complexes of Keap1 dimer and one molecule of bivalent compounds. The best bivalent molecule 8 encompasses robust capacity to degrade Keap1 as a homoPROTACKEAP1. It efficaciously suppresses inflammatory cytokines in extensively different cells, including human nasal epithelial cells. Moreover, in an AR mouse model, we confirmed that the chemical degradation induced by homoPROTACKEAP1 led to therapeutic benefits in managing AR symptoms, oxidative stress and inflammation. In summary, our findings underscore the efficacy of targeting the Keap1 system through the homoPROTAC-ing technology as an innovative and promising treatment strategy for the incurable allergic disorders.

Biliary atresia is often complicated with portal hypertension, which induces a series of hemodynamic changes leading to splenomegaly. Splenomegaly is a common in patients with biliary atresia, which indicates the status of portal hypertension, esophageal varices, and the progression of hepatic fibrosis. Furthermore, it can help monitor the native liver survival status after Kasai procedure and the need for liver transplantation. For patients with biliary atresia presenting splenomegaly and/or hypersplenism, the treatment strategy, involving the pharmacological or surgical options, should be individually selected based on specific clinical condition. This article reviews the value of splenomegaly in the diagnosis and management of biliary atresia, aiming to provide references for clinical practice.
