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.

OBJECTIVE: To explore the correlation between single nucleotide polymorphisms (SNPs) of ARID5B gene and the risk of acute lymphoblastic leukemia (ALL) and minimal residual disease (MRD) in children of Hui and Han nationality in Ningxia. METHODS: In this case-control study, 54 ALL children and control group with matched age, sex and nationality were detected for the polymorphism of ARID5B gene using fluorescence resonance energy transfer technique, and the susceptibility of different ALL genotypes and their correlation with MRD were analyzed. RESULTS: There were no significant differences in genotype and allele frequency of rs10994982, rs7089424, rs10740055, rs7073837, rs4245595 and rs7090445 between the two groups (P >0.05). At the locus of rs10821936, the frequencies of T/T genotype and T allele in ALL group were significantly higher than those in the control group (both P < 0.05). The C/C genotype of ARID5B gene SNP rs10821936 was a risk factor for early MRD positive in ALL children ( P < 0.05). CONCLUSION ARID5B gene SNP rs10821936 is related to the development of childhood ALL and MRD.

Objective:To analyze application effect of Failure Mode and Effects Analysis(FMEA)in the maintenance and upkeep for equipment in operating room.Methods:The process of FMEA mode was analyzed,and a strategy about maintenance and upkeep for equipment in operating room on the basis of FMEA was formulated from some aspects included preparation stage,analysis for failure mode(FM),construction for the system of prevention,maintenance and upkeep,and improvement and analysis for results.Sixty used equipment in the operating room of Shiyan Taihe Hospital(Affiliated Hospital of Hubei University of Medicine)from January to December 2023 were selected.According to different management methods for equipment,the conventional management mode and the FMEA management mode were respectively selected to conduct maintenance and upkeep for equipment in operating room,with 30 equipment in each management mode.The incidences of adverse events,the satisfaction scores of operators,and the qualities of maintenance and upkeep for equipment of the two kinds of management modes were compared.Results:The number of occurring inadequate preparation of surgical associated facilities,non-standardized operation of surgical equipment,and incidence of faliures in surgical equipment were respectively in 30 equipment in operating room that adopted FMEA management mode,and the total incidence of adverse events was 6.67%(2/30),which was lower than 36.67%(11/30)that adopted conventional management mode,and the difference was statistically significant(x2=7.954,P<0.05).The satisfaction scores of the operators of operating equipment for the operational quality,usage operation,and maintenance and upkeep of the equipment that received the FMEA management mode in operating room were respectively(92.22±3.36),(91.69±2.25)and(93.25±3.69)points,all of which were higher than those that received conventional management mode,and the differences were statistically significant(t=15.418,17.415,16.639,P<0.05).The average increase extents of the response time for fault,repair time for fault,and the cost of operation and maintenance that adopted FMEA management mode were respectively(2.36±0.59)h,(4.25±2.11)h and(1.89±0.14)%for equipment in operating room,all of which were less than those that adopted conventional management mode,and the differences were statistically significant(t=9.943,12.050,11.069,P<0.05).The failure frequency of equipment of adopting FMEA management mode was(1.54±0.21)times per year,which was lower than that of adopting conventional management mode.The average success rate of opening equipment of adopting FMEA management mode was(90.69±3.59)%,which was higher than that of adopting conventional management mode,and the differences of the above two indicators between two modes were statistically significant(t=15.184,18.779,P<0.05).Conclusion:The application of FMEA in the maintenance and upkeep for medical equipment in the operating room can assess the operational quality of the equipment,and carry out preventive operation and maintenance,and reduce the incidence of failures in equipment,and decrease costs for maintenance,and improve the clinical service level for the equipment.

Aim To investigate the effects of rosavin on hepatocellular steatosis and its mechanism of action.Methods AML-12 and HepG2 cells were induced to undergo hepatocellular steatosis by free fatty acids(FFA),and the optimal inducing concentration was determined by oil red O staining and CCK-8 assay.The cell activity was detected by CCK-8 assay after ro-savin treatment,and the lipid droplet accumulation was observed by oil red O staining.The levels of triglycer-ide(TG),total cholesterol(TC),glutamic oxalacetic transaminase(AST),glutamic pyruvic transaminase(ALT),superoxide dismutase(SOD),glutathione per-oxidase(GSH-Px),and malondialdehyde(MDA)were detected by kits.The potential targets of rosavin in non-alcoholic fatty liver disease(NAFLD)were ana-lyzedby network pharmacology and molecular docking,and the expression of core candidate targets before and after the rosavin intervention was detected by real-time fluorescence quantitative PCR.Results Hepatocyte steatosis was induced by FFA,and the intervention of rosavin(25,50 μmol·L-1)reduced the number of intracellular lipid droplets in hepatocytes in a dose-de-pendent manner,also lowered the cellular levels of TG,TC,AST,ALT,elevated the levels of SOD and GSH-Px,and reduced the levels of MDA.Network pharma-cological analysis and molecular docking yielded five core candidate targets:NOS3,MAPK14,PPARG,TNF-α,and IGF-1,and real-time fluorescence quantitative PCR showed that the action of loxavir significantly re-duced the gene expression of TNF-α and PPARG in hepatocytes after FFA induction.Conclusions Rosa-vin can attenuate the inflammatory response,oxidative stress level,and lipid accumulation in hepatocytes by modulating TNF-α and PPARG,thereby ameliorating FFA-induced hepatocellular steatosis.

Objective:To establish a detection method for fatty acid composition and methoxylaniline value in pharmaceutical excipient castor oil.Methods:The detection of fatty acid composition involves pre-test of the sam-ple using the methanol sodium methylation method,followed by direct injection analysis using gas chromatography,and finally calculating the content of each fatty acid composition using the area normalization method with correction factors.The detection of methoxylaniline value is achieved by dissolving and diluting the sample with isooctane:isopropanol(8∶2,volume ratio),reacting with 4-methoxylaniline,measuring the absorbance at a wavelength of 350 nm,and calculating the methoxylaniline value.Results:Under the composition of fatty acids,the 8 kinds of fatty acids have good separation degree.The methyl ricinoleate and methyl stearate have good linear relationship in the range of 0.1-5.0 mg·mL-1.The repeatabilityand intermediate precision(RSD)ofthe determination results of each fatty acid in the sample are all less than 5%.It is also found that only α-type of linolenic acid is present in castor oil,without γ-type.In the determination of methoxyaniline value,the blank solvent does not interfere with the determination of the sample,and the repeatability RSD is 3.6%.Conclusion:The detection method for fatty acid composition and meth-oxylaniline value established in this article is accurate and reliable,and can be used for the detection of fatty acid composition and methoxylaniline value in pharmaceutical excipient castor oil.

Objective:To explore the medication thinking and compatibility rules of TCM for the treatment of diabetic nephropathy (DN).Methods:Relevant journal literature of TCM for the treatment of DN was retrieved from CNKI, Wanfang Data, VIP, and CBM from January 1, 2000 to December 31, 2023, and a database was established through Excel 2016. Python 3.10 and the ancient and modern medical record cloud platform 2.3.5 were used to conduct Latent Dirichlet Allocation (LDA) topic modeling and association rule analysis to explore the thinking and compatibility rules of TCM prescriptions in the literature.Results:A total of 474 articles were included in the study, including 474 prescriptions, involving 260 kinds of Chinese materia medica, of which 40 kinds of Chinese materia medica with a frequency of ≥ 30, mainly Astragali Radix, Salviae Miltiorrhizae Radix et Rhizoma, Dioscoreae Rhizoma, Poria, and Corni Fructus, etc. The LDA topic model identified three groups of prescriptions, including four classic prescriptions: Liuwei Dihuang Pills, Taohong Siwu Decoction, Erzhi Pills, and Wuling Powder. The commonly used drug combinations extracted by association rules were: Rhizoma Alismatis - Poria, Cortex Moutan Radicis-Fructus Corni and Cortex Moutan Radicis - Rhizoma Dioscoreae.Conclusions:The main therapeutic principle of TCM in treating DN is to nourish the yin and tonify the kidney, supplemented by drugs that promoting blood circulation for removing blood stasis as well as promoting urination and draining dampness. In clinical application, modern doctors tend to use classic prescriptions such as Liuwei Dihuang Pills, Erzhi Pills, Taohong Siwu Decoction, and Wuling Powder as the basis, and modify them according to the specific conditions of patients. The LDA topic model can extract valuable prescription information from a large number of modern TCM literature, providing new perspectives and ideas for the study of clinical medication rules in TCM.

Glutamine provides carbon and nitrogen to support the proliferation of cancer cells. However, the precise reason why cancer cells are particularly dependent on glutamine remains unclear. In this study, we report that glutamine modulates the tumor suppressor F-box and WD repeat domain-containing 7 (FBW7) to promote cancer cell proliferation and survival. Specifically, lysine 604 (K604) in the sixth of the 7 substrate-recruiting WD repeats of FBW7 undergoes glutaminylation (Gln-K604) by glutaminyl tRNA synthetase. Gln-K604 inhibits SCFFBW7-mediated degradation of c-Myc and Mcl-1, enhances glutamine utilization, and stimulates nucleotide and DNA biosynthesis through the activation of c-Myc. Additionally, Gln-K604 promotes resistance to apoptosis by activating Mcl-1. In contrast, SIRT1 deglutaminylates Gln-K604, thereby reversing its effects. Cancer cells lacking Gln-K604 exhibit overexpression of c-Myc and Mcl-1 and display resistance to chemotherapy-induced apoptosis. Silencing both c-MYC and MCL-1 in these cells sensitizes them to chemotherapy. These findings indicate that the glutamine-mediated signal via Gln-K604 is a key driver of cancer progression and suggest potential strategies for targeted cancer therapies based on varying Gln-K604 status.

High mobility group box protein 1(HMGB1)is one of the most widely expressed protein member in the HMGs family,which is well known for its involvement in the body inflammatory response.Previous researches have found that it plays a significant role in cell migration,immune identification and neuroprotection.Spinal cord injury is a disease that causes severe damage to the nervous system,and neural circuits are disrupted after a spinal cord injury,which leads to many conditions including ischemia and hypoxia,inflammatory responses,demyelinating lesions,and glial scar formation that are detrimental to nerve regeneration and repair,making it one of the most difficult diseases to treat in the modern spinal surgery field.HMGB1 is upregulated after spinal cord injury,thereby regulating neuroinflam-matory responses,and participating in the neuronal apoptosis,promoting neuronal regeneration,and inducing neural stem cell differentiation and migration,which plays an important role in the process of neural function recovery.This paper summarizes the structure and function of HMGB1,as well as its role in spinal cord injury,in order to provide direction for founding therapeutic target for neurological function recovery after spinal cord injury.

Objective:To investigate the prevalence and risk factors of overweight and obesity among Chinese children aged 3-18 years from 11 provinces, antonomous regions, or municipalities.Methods:This national cross-sectional community health survey utilized a multistage stratified cluster-random sampling method to recruit 193 997 nationally representative participants from 11 provinces, autonomous regions, or municipalities between January 2017 and December 2019. All participants underwent physical examinations, and their caregivers completed questionnaires assessing participants′ dietary, lifestyle, familial, and perinatal information. Multilevel multinomial logistic regression models were employed to identify the potential risk factors.Results:The cohort comprised 193 997 children (102 178 boys, 91 819 girls),aged (10±4) years. Overall prevalence rates were 30 574(15.8%)overweight children and 17 217(8.9%) obesity children. Boys exhibited higher overweight and obesity rates than girls (17.0% (17 368/102 178) vs. 14.4% (13 206/102 178), 11.3% (11 553/91 819) vs. 6.2% (5 664/91 819), χ2=249.12,1 578.69,both P<0.001). The detection rates of obesity in Tanner stage 2 and 3 were the highest in boys and girls, with 13.4%(2 231/16 665) and 8.6%(880/10 221) respectively. Risk factors for obesity included parental overweight (paternal OR=2.34 and maternal OR=2.29), annual household income of 100 000-200 000 yuan (compared with<100 000 yuan, OR=1.04), higher paternal education (compared with below high school,high school and a college education OR=1.09,1.14), birth weight >4.0 kg (≤5 and>5 years old OR=1.74, 1.44,respectively), and western food consumption≥1 time/month (compared with<1, 1-2, 3-4,>4 times/month OR=1.36, 1.30, 1.67(≤5 years), 1.19, 1.16, 1.15 (>5 years), respectively) (all P<0.05). Conversely, coarse grain intake≥1 times/week (compared with<1 times/week, every day, 3-4, 1-2 times/week OR=0.74, 0.80, 0.71 (≤5 years), 0.75, 0.87, 0.90(>5 years), respectively, all P<0.05) was associated with reduced obesity risk. Conclusions:Obesity epidemiology in children demonstrates significant heterogeneity across age, gender, geographic regions, and pubertal stages. It is necessary to establish a personalized prevention and control strategy.
