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 gain insights into the biological characteristics of different populations of Culex tritaeniorhynchus within and around the Yellow Sea wetland from the perspective of the occurrence of resistance, we investigated the levels of resistance to deltamethrin and kdr gene mutation in the wetland and its peripheral areas. Methods Specimens were collected from Cx. tritaeniorhynchus populations at two monitoring sites in the Rare Bird National Nature Reserve and Tiaozi Ni Wetland Scenic Area, and also from two populations in Yancheng City and the Liuhe District of Nanjing, and the resistance of these mosquitoes to deltamethrin was determined using the CDC biotest bottle method. For each concentration of deltamethrin assessed, a random subset of exposed specimens was selected for amplification of the kdr gene fragment, followed by Sanger sequencing to identify and analyze resistance-associated mutations. Results The LC50 levels of deltamethrin among mosquitoes from the four populations in Luhe, Yancheng, the Rare Bird National Nature Reserve and the Tiaozi Ni Wetland Scenic Area were 2.048 5, 7.798 2, 3.473 3, and 17.695 5 mg/mL, respectively, with corresponding concentrations of deltamethrin ranging from 0.005 to 5.000,0.050 to 50.000,0.050 to 25.000 and 0.050 to 50.000 mg/mL, respectively. Furthermore, the ranges of the KT50 values were 11.76-107.43, 67.05-216.30,29.77-107.43 and 28.40-329.51 min; the 1-h knockdown rates were 34.58%-99.15%, 9.52%-43.80%, 55.09%-73.01%, and 10.09%-68.07%; and the 24-h mortality rates were 12.15%-67.52%,9.52%-79.56%,13.17%-82.21%, and 11.01%-78.99%, respectively. With respect to kdr gene mutation, we assayed a total of 63,70,59, and 57 mosquitoes for the four populations, for which we detected L1014F mutation frequencies of 14.29%, 35.00%, 20.34%, and 31.58%, respectively, with a majority of these mutations being heterozygous for resistance. In addition, five adult mosquitoes were identified has having synonymous mutations at site 1011[i. e. , AAT(asparagine)mutation to AAC(asparagine)]. Conclusions Our findings revealed the clear resistance of Cx. tritaeniorhynchus to deltamethrin in the Yancheng region of the Yellow Sea wetland, and the resistance phenotype and kdr frequency of Cx. tritaeniorhynchus in the wetland environment were comparable to those of Cx. tritaeniorhynchus in the wetland environment, thereby indicating that the resistance of different populations of Cx. tritaeniorhynchus was homogeneous under the pressure of different insecticide selection within and around the wetland. However, the underlying mechanisms need to be further studied.

Background:
High-mobility group box protein 1 (HMGB1) is a chromatin-binding protein involved in arthritis, ischemia, sepsis, atherosclerosis, neurodegenerative disorders, meningitis, and cancer. HMGB1 exhibits dual roles in cancer, acting as either a tumor suppressor or oncoprotein depending on context.
Objective:
This research aimed to elucidate HMGB1’s functional significance in cutaneous squamous cell carcinoma (cSCC).
Methods:
We overexpressed HMGB1 in cSCC cell lines using recombinant adenovirus and examined its effects on cell proliferation, colony formation, and cell migration.
Results:
Immunohistochemical analysis revealed elevated HMGB1 expression levels in cSCC tissue relative to normal epidermis. To assess the influence of HMGB1, we employed recombinant adenoviruses expressing HMGB1 to transduce SCC cell lines (SCC12 and SCC13). Enhanced HMGB1 expression significantly promoted cellular proliferation and colony formation capacity.Notably, HMGB1 overexpression elevated the levels of proliferation regulators, including P63, SOX2, CDK4 and CDK6. Furthermore, HMGB1 overexpression substantially enhanced tumor invasiveness, accompanied by upregulation of epithelial-mesenchymal transition (EMT) biomarkers. Mechanistically, overexpression of HMGB1 enhanced transforming growth factor-β signaling by increasing phosphorylation of SMAD2/3, the key mediators of EMT.
Conclusion
These data imply that HMGB1 acts as a tumor-promoting factor in cSCC.

OBJECTIVE To investigate the effect and mechanism of Tangzhi formula(TZF) on improving glucose and lipid metabolism disorders in type 2 diabetes mellitus (T2DM) rats.METHODS Thirty SPF-grade SD rats were used to establish a T2DM rat model through high-fat diet feeding combined with intraperitoneal injection of streptozotocin. After successful modeling, the rats were divided into the model group, metformin group (positive control, 0.18 g/kg), and TZF low-, medium-, and high-dose groups (5, 10, and 20 g/kg), with 6 rats in each group. An additional 6 rats were selected as the blank group. The rats in each group were orally administered the corresponding volume of drug solution or saline, and continuous dosing was performed for 6 weeks, once daily. Fasting blood glucose (FBG), area under the curve of oral glucose tolerance test (OGTT-AUC), area under the curve of intraperitoneal insulin tolerance test (IPITT-AUC), serum total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) levels were measured. Hematoxylin-eosin (HE) staining and oil red O staining were used to observe hepatic pathological morphology and lipid deposition. Differentially expressed proteins in liver tissues were screened by proteomics analysis, and key proteins in signaling pathways were verified by Western blot and immunofluorescence staining.RESULTS Compared with the blank group, the levels of FBG, OGTT-AUC, IPITT-AUC, LDL-C, TG, and TC in the model group were significantly increased ( P <0.05), while HDL-C level was significantly decreased ( P <0.05); the liver tissues showed disordered hepatic cords, punctate necrosis of hepatocytes, and significant lipid deposition, the NAFLD activity score and positive area of lipid droplets were significantly increased( P <0.05). Compared with the model group, the above indicators in TZF low-, medium-, and high-dose groups and metformin group were significantly reversed ( P <0.05); hepatic pathological injury and lipid deposition were alleviated. Proteomics results showed that a total of 442 differentially expressed proteins were screened between the model group and the blank group, and 358 differentially expressed proteins were screened between the TZF high-dose group and the model group. Among these differentially expressed proteins, multiple proteins closely related to glucose and lipid metabolism showed a reversal trend after TZF intervention. Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis showed that the peroxisome proliferator-activated receptor (PPAR) signaling pathway was significantly enriched. The validation experiment results showed that TZF could significantly up-regulate the expression of PPARα, PPARγ, and apolipoprotein A1 (ApoA1) in rat liver tissues ( P <0.05), and down-regulate the expression of stearoyl-CoA desaturase 1 (SCD1) and perilipin 2 (PLIN2) ( P <0.05).CONCLUSIONS TZF can improve glucose and lipid metabolism disorders in T2DM rats; its mechanism may be related to the activation of the PPAR signaling pathway and the regulation of downstream lipid metabolism-related proteins SCD1, PLIN2, and ApoA1.

Objective:To construct a multidisciplinary collaborative intelligent prevention and treatment system for orthopedic thrombophilia based on advanced intelligent analysis technology and to evaluate its application effectiveness in the management of orthopedic thrombophilia.Methods:Established a clinical multidisciplinary medical team guided by early warning management and human-computer interaction theory, and builded a multidisciplinary collaborative intelligent prevention and treatment system for orthopedic thrombophilia based on intelligent analysis technology.Adopting a prospective pre-and post control study method, 674 orthopedic inpatients at the Second Affiliated Hospital of Nanchang University from February 2021 to October 2022 were selected as study participants by convenient sampling method and divided into a control group (308 cases) and an observation group (366 cases) according to their admission periods. The control group underwent conventional management methods for thrombophilia. In contrast, the observation group utilized a multidisciplinary collaborative intelligent prevention and treatment system for orthopedic thrombophilia for intelligent management methods. The two groups were compared regarding risk assessment rates, assessment accuracy, assessment efficiency, dynamic assessment completion rate, knowledge awareness rates, implementation rates of multidisciplinary collaborative preventive measures, and thrombophilia incidence rates.Results:The multidisciplinary collaborative intelligent prevention and treatment system for orthopedic thrombophilia mainly included four personnel ports (doctor end, nurse end, patient or caregiver end, medical quality control end) and eight modules (patient intelligent scoring, risk grading warning, dynamic evaluation of prevention contraindications, prevention measure decision-making, health education, inpatient data monitoring, department indicator statistics, medical management). Both groups of patients completed the study. There were 238 males and 70 females in the control group, aged (42.83 ± 8.69) years old. There were 278 males and 88 females in the observation group, aged (42.35 ± 8.13) years old. The risk assessment rate, assessment accuracy rate, and dynamic assessment completion rate of the observation group for thrombophilia were 100.00% (366/366), 98.90% (362/366), and 100.00% (366/366), respectively, all higher than the control group's 94.15% (290/308), 90.58% (279/308), and 91.55% (282/308), and the differences were statistically significant ( χ2=21.99, 24.88, 32.16, all P<0.01). The knowledge awareness rate of preventing thrombophilia among high-risk patients in the observation group was 95.90% (211/220), the implementation rates of basic prevention, physical prevention, drug prevention, and combined prevention in the multidisciplinary collaborative prevention measures were 87.37% (173/198), 97.72% (215/220), 39.09% (86/220), 46.37% (102/220), and 27.73% (61/220), respectively, all higher than the control group's 85.86% (170/198), 24.74% (49/198), 30.81% (61/198), and 12.12% (24/198), and the differences were statistically significant ( χ2 values were 9.81-20.19, all P<0.05). The risk assessment time for the observation group was (3.95 ± 1.03) minutes, and the incidence of thrombophilia was 1.91% (7/366), both lower than the control group's (9.56 ± 1.65) minutes and 7.47% (23/308), with statistically significant differences ( t=53.78, χ2=6.33, both P<0.05). Conclusions:The application of the multidisciplinary collaborative intelligent prevention and treatment system for orthopedic thrombophilia has improved the implementation rate of prevention and treatment interventions by medical staff, increased job satisfaction, and also enhanced the awareness rate of prevention knowledge among patients, thereby improving the management status of thrombophilia in orthopedic inpatients.
