ObjectiveTo summarize the application experience of the "Three-Separation" model in the pre-service training of laboratory animal practitioners and scientifically evaluate its training effectiveness. MethodsA retrospective analysis was conducted on 8 009 practitioners who participated in pre-service training at the Fujian Provincial Laboratory Animal Training Base from January 2010 to December 2025. Among them, 1 250 trainees from January 2010 to December 2017 were included in the control group (traditional training model), and 6 759 trainees from January 2018 to December 2025 were included in the evaluation group ("Three-Separation" model, based on separating job requirements, differentiating exam content, and categorizing exam methods). Meanwhile, a questionnaire survey was conducted to evaluate training effectiveness, yielding 1 624 valid questionnaires (585 from the control group and 1 039 from the evaluation group). The "Three-Separation" model simultaneously optimized fee structures to improve affordability and inclusiveness. The comprehensive competencies and training satisfaction of the two groups after training were compared and analyzed using the independent sample t-test, χ² test, and Wilcoxon rank-sum test. ResultsThe overall satisfaction rate of the evaluation group was 92.49% (961/1 039), significantly higher than that of the control group (77.78%, 455/585), with a highly significant difference (χ²=72.50, P<0.001). The evaluation group showed a more favorable distribution of positive, neutral, and negative ratings in dimensions such as course pertinence, time flexibility, assessment rationality, and reasonableness of fees, and the positive rating rates were highly significantly higher than those in the control group (P<0.001). The comprehensive pass rate of the evaluation group (95.53%) was significantly higher than that of the control group (86.24%), with a highly significant difference (P<0.001). ConclusionThe scientific application of the "Three-Separation" model can accurately match the competency requirements of different positions, optimize the training and assessment system, reduce participation barriers by making training fees more affordable and accessible, effectively improve the comprehensive quality and training satisfaction of laboratory animal practitioners, achieve better teaching outcomes, and provide replicable and promotable practical references for the standardized upgrading of the training system in the laboratory animal industry and other industries.

Objective:To analyze the current research hotspots and trends of traditional Chinese medicine (TCM) treatment for neurogenic bladder (NB).Methods:The Chinese and English articles on TCM treatment of neurogenic bladder were searched in CNKI, Wanfang Database, PubMed, and Web of Science from the inception to May 31, 2024, using the terms "neurogenic bladder" "intervention" "treatment" "clinical" "Chinese medicine" "electroacupuncture" "acupuncture", and "moxibustion". VOSviewer and Citespace bibliometric software were used to analyze the publication trend, authors, research institutions, source journals and keywords of these articles.Results:A total of 776 Chinese articles and 253 English articles on the diagnosis and treatment of NB by traditional Chinese medicine were retrieved, the number of publications was increasing every year. Most Chinese papers came from Shandong University of Traditional Clinese Medicine, and most English papers came from Sun Yat-sen University.

In order to investigate the effect of SIRT2 on tight junctions and endoplasmic reticulum stress in liver tissues of cold-treated mice,10 each of 5-week-old male C57BL/6 mice and SIRT2 knockout mice were selected and randomly divided into the wild-type room-temperature control group(WT Control),the wild-type cold-treated group(WT Cold),the SIRT2 knockout+room-temperature control group(KO Control)and SIRT2 knockout+cold treatment group(KO Cold).Mice in the room-temperature control group were kept at a temperature of(24+2)℃,and the cold-treatment group was placed in a(4+2)℃ artificial climate chamber for 3 h of random stimu-lation per day for 3 weeks.H&E staining,Masson staining,and transmission electron microscopy were employed to examine the microscopic and ultrastructural changes in mouse liver;AST and ALT concentrations in mouse serum were detected by biochemical analyzers;Western blot analysis was used to detect the expressions of tight junction-related proteins(Claudin1,Occludin),endo-plasmic reticulum stress-related proteins(GRP78,CHOP,XBP1,p-eIF2α,eIF2α),and pro-inflam-matory cytokines(TNF-α,IL-1β,IL-6).The results showed that compared with WT Control,the liver lobular structure of WT Cold and KO Control mice was unclear,hepatic cord arrangement was disordered,cytoplasm was loose,white vacuoles appeared,a small amount of collagen deposi-tion and fibroplasia,mitochondria were slightly swollen in hepatocytes,and endoplasmic reticulum was unevenly distributed,while the serum concentrations of AST and ALT were increased(P＜0.050,P＜0.010),and the liver tissues showed decreased protein expression of Occludin and Clau-din1(P＜0.050,P＜0.010,P＜0.001),and increased protein expression of GRP78,CHOP,XBP1,p-eIF2α/eIF2α,TNF-α,IL-6,and IL-1β(P＜0.050,P＜0.010,P＜0.001);compared with the KO Control,KO Cold mice showed a large number of white vacuoles,a small number of balloon-like lesions,inflammatory cell infiltration,obvious collagen deposition and fibroplasia,mitochondrial swelling in hepatocytes,mitochondrial ridge reduction,endoplasmic reticulum thickening,and ser-um AST and ALT concentrations increased(P＜0.010),and in liver tissue,the protein expression of Occludin and Claudinl decreased(P＜0.010),while the protein expression of GRP78,CHOP,XBP1,p-eIF2α/eIF2α,TNF-α,IL-6 and IL-1β increased(P＜0.050,P＜0.010,P＜0.001).The re-sults showed that SIRT2 knockdown could aggravate the liver tissue tight junction damage caused by cold treatment,induce endoplasmic reticulum stress,and further promotes the inflammatory re-sponse.

Acute kidney injury (AKI) has high morbidity and mortality, but effective clinical drugs and management are lacking. Previous studies have suggested that macrophages play a crucial role in the inflammatory response to AKI and may serve as potential therapeutic targets. Emerging evidence has highlighted the importance of forkhead box protein O1 (FoxO1) in mediating macrophage activation and polarization in various diseases, but the specific mechanisms by which FoxO1 regulates macrophages during AKI remain unclear. The present study aimed to investigate the role of FoxO1 in macrophages in the pathogenesis of AKI. We observed a significant upregulation of FoxO1 in kidney macrophages following ischemia-reperfusion (I/R) injury. Additionally, our findings demonstrated that the administration of FoxO1 inhibitor AS1842856-encapsulated liposome (AS-Lipo), mainly acting on macrophages, effectively mitigated renal injury induced by I/R injury in mice. By generating myeloid-specific FoxO1-knockout mice, we further observed that the deficiency of FoxO1 in myeloid cells protected against I/R injury-induced AKI. Furthermore, our study provided evidence of FoxO1's pivotal role in macrophage chemotaxis, inflammation, and migration. Moreover, the impact of FoxO1 on the regulation of macrophage migration was mediated through RhoA guanine nucleotide exchange factor 1 (ARHGEF1), indicating that ARHGEF1 may serve as a potential intermediary between FoxO1 and the activity of the RhoA pathway. Consequently, our findings propose that FoxO1 plays a crucial role as a mediator and biomarker in the context of AKI. Targeting macrophage FoxO1 pharmacologically could potentially offer a promising therapeutic approach for AKI.

OBJECTIVES: To investigate the therapeutic effect of the natural compound niranthin on Crohn's disease-like colitis in mice and explore the underlying molecular mechanisms. METHODS: In a mouse model of colitis induced by 2,4,6-trinitro-benzenesulfonic acid (TNBS), the therapeutic effect of niranthin was evaluated by observing the changes in body weight, disease activity index (DAI), and colon length of the mice. The levels of inflammatory cytokines (IL-6, IL-1β, TNF-α, IL-17A and IL-10) in the intestinal mucosal tissue were detected using ELISA and quantitative real-time PCR (qRT-PCR). TUNEL staining and Western blotting were used to assess intestinal epithelial cell apoptosis and the expressions of Bcl-2 and Bax. The expression levels of tight junction proteins (ZO-1 and claudin-1) and the activation of the p38/JNK signaling pathway were investigated using Western blotting, and diprovocim intervention experiments were conducted to explore the molecular regulatory mechanism of niranthin. RESULTS: Niranthin treatment significantly increased body weight of TNBS-treated mice, lowered the DAI and histological inflammation scores, and increased colon length of the mice. The niranthin-treated mouse models showed obviously reduced protein and mRNA levels of IL-6, IL-1β, IL-17A, and TNF-α and upregulated expression of IL-10 in the colon tissue. TUNEL staining and Western blotting demonstrated that niranthin significantly inhibited intestinal epithelial cell apoptosis and activated the anti-apoptotic pathway in the mouse models. Niranthin treatment obviously upregulated the expression levels of ZO-1 and claudin-1 and downregulated the phosphorylation levels of p38 and JNK in the colon tissues of the mice. Diprovocim intervention obviously attenuated the inactivation of the p38/JNK signaling pathway induced by niranthin in the mouse models. CONCLUSIONS Niranthin ameliorates TNBS-induced Crohn's disease-like colitis in mice by inhibiting intestinal epithelial cell apoptosis and protecting the integrity of the intestinal barrier via regulating the activation of the p38/JNK signaling pathway.

Stress refers to the non-specific responses of a stimulated body to different stressors and the subsequent maintenance or restoration of internal environmental homeostasis.Adverse stress reactions lead to general balance disruption and may cause digestive,neurological,and endocrine disorders,and decreased immune capacity,which seriously impact host health.As the core compo-nent of intestinal micro-ecology,the intestinal flora can greatly alter its own composition,distribu-tion,function,metabolic product output,and other aspects during stress,which cause disorders and aggravate homeostatic imbalance in internal environments.While the intestinal flora is of great sig-nificance to animal medicine and agricultural production,little is known about stress and its impact on intestinal flora.Therefore,we briefly reviewed the impact of stress on animal intestinal flora in combination with the latest research and provided theoretical insights on intestinal health research.
