Objective To investigate how puerarin affects cognitive behavior and pro-inflammatory factors in the hippocampal formation of 52%(v/v)alcohol exposure/withdrawal in mice and reveal the underlying neuroimmunological mechanism by which puerarin improves alcohol-induced cognitive dysfunction.Methods A total of 120 adult female mice were randomly divided into control,52%alcohol,puerarin+52%alcohol,and normal saline(NS)+52%alcohol groups.The cognitive function of the animals was assessed using the Morris water maze,and the expression of target proteins in the hippocampal formation was detected using Western blotting and immunohistochemi-stry.Results The cognitive ability of mice in the puerarin+52%alcohol group was significantly higher than that of mice in the 52%alcohol and NS+52%alcohol groups.At the 20th hour after alcohol withdrawal,IL-6,TNF-α,and IL-1β expressions in the hippocampal formation of the puerarin+52%alcohol group were higher than those of the 52%and NS+52%alcohol groups.However,no significant difference could be observed in the expression levels of these cytokines between the puerarin+52%alcohol and control groups.Con-clusion In a female mouse model chronically exposed to 52%alcohol,puerarin can improve cognitive dysfunction during acute alcohol withdrawal,potentially related to the involvement of puerarin in regulating pro-inflammatory factor expressions in murine hippocampus formation.

To perform the phylogenetic characterization of an isolated porcine rotavirus(PoRV)and investigate its pathogenicity in suckling mice and piglets.A G4P[23]genotype PoRV strain JSJR2023 was successfully isolated from the diarrheic piglet feces through propagation in MA104 cells.The viral proliferation kinetics were analyzed using TCID50 assays,followed by complete genome sequencing through Sanger sequencing platforms.Comprehensive genotyping and phylogenetic reconstruction were conducted using MEGA7.0 with maximum likelihood algorithms.Pathogenicity was assessed in the following animal models:5-day-old C57BL/6 mice and 3-day-old piglets.Multidimensional evaluation included clinical monitoring(diarrhea scoring,growth parameters),virological detection,and histopathological analysis of intestinal tissues.The virus strain JSJR2023 could replicate efficiently in MA104 cells,achieving peak titers of 107.5 TCID50/mL.Whole genome genotype analysis showed that the strain belonged to G4-P[23]-I5-R1-C1-M1-A8-N1-T1-E1-H1.Phylogenetic analysis indicated that the VP3 and NSP4 genes of JSJR2023 strain were most closedrelated to human species rotaviruses,suggesting genetic reassortment between human and porcine RV strains.The animal experiments in suckling mice showed that the JSJR2023 strain infection caused diarrhea symptoms,intestinal edema and congestion,and shedding of intestinal villus epithelial cells.The pathogenicity experiments in piglets showed that compared with the control group,the challenged group of pig-lets had severe diarrhea symptoms,accompanied by reduced appetite and listlessness.Post-mortem examination revealed that the intes-tines were significantly thinner,congested,and filled with yellow watery contents.The challenged piglets showed typical pathological changes such as thinning of the intestinal wall and shortening and shedding of intestinal villi.In conclusion,this study successfully iso-lated a human-porcine recombinant G4P[23]PoRV strain and established the infection models in suckling mice and piglets,providing important tools for investigating the pathogenic mechanism of PoRV,evaluating vaccines and developing antiviral drug.

Objective:To evaluate the efficacy and safety of modified endoscopic submucosal dissection (ESD) utilizing a mushroom extraction method for gastric ectopic pancreas.Methods:From June 1, 2009 to June 30, 2023, data of 190 patients (191 lesions) with pathologically confirmed heterotopic pancreas who underwent resection using modified ESD with mushroom extraction method in Shandong Second Provincial General Hospital ( n=99) and the 960th Hospital of the PLA Joint Logistics Support Force ( n=91) were retrospectively analyzed. The clinical characteristics and endoscopic and endoscopic ultrasonography (EUS) features were summarized and the treatment effects of the modified ESD was evaluated. The complications and follow-up recurrence were analyzed. Results:Preoperative EUS showed that most lesions originated from the submucosa and often involved multiple layers, invading the muscularis propria in 12 cases. A total of 191 gastric lesions included 174 in the gastric antrum, 2 pyloric canal, 6 gastric body, 7 gastric angle and 2 gastric fundus. The long diameter of the lesions ranged from 0.5-4.0 cm. All patients underwent modified ESD with the mushroom extraction method, and the complete removal rate of specimens was 99.5% (190/191). The operation time was 0.5-2.5 h. There were 10 cases of intraoperative perforation; 1 case of postoperative delayed perforation, 1 case of delayed hemorrhage, and 3 cases of short-term fever. Patients were followed up for 3-5 years after the operation, and no recurrence or metastasis was found.Conclusion:The modified ESD technique incorporating mushroom extraction proves to be a safe and effective approach for the complete removal of gastric ectopic pancreas, minimizing the risk of recurrence and residual pancreatic tissue.

Gene regulation relies on the precise binding of transcription factors (TFs) at regulatory elements, but simultaneously detecting hundreds of TFs on chromatin is challenging. We developed cFOOT-seq, a cytosine deaminase-based TF footprinting assay, for high-resolution, quantitative genome-wide assessment of TF binding in both open and closed chromatin regions, even with small cell numbers. By utilizing the dsDNA deaminase SsdAtox, cFOOT-seq converts accessible cytosines to uracil while preserving genomic integrity, making it compatible with techniques like ATAC-seq for sensitive and cost-effective detection of TF occupancy at the single-molecule and single-cell level. Our approach enables the delineation of TF footprints, quantification of occupancy, and examination of chromatin influences on TF binding. Notably, cFOOT-seq, combined with FootTrack analysis, enables de novo prediction of TF binding sites and tracking of TF occupancy dynamics. We demonstrate its application in capturing cell type-specific TFs, analyzing TF dynamics during reprogramming, and revealing TF dependencies on chromatin remodelers. Overall, cFOOT-seq represents a robust approach for investigating the genome-wide dynamics of TF occupancy and elucidating the cis-regulatory architecture underlying gene regulation.
