Aim To study the therapeutic effect of al-licin on senna-induced diarrhea in mice and to explore the underlying mechanism.Methods Forty-eight C57BL/6J mice were randomly divided into six groups:control,model,loperamide positive control group(2 mg·kg-1),allicin low-dose group(6 mg·kg-1),allicin medium-dose group(12 mg·kg-1)and allicin high-dose group(18 mg·kg-1).Except for the con-trol group,the diarrhea model was induced in the other groups by intragastric administration of senna leaf ex-tract.After drug administration,several diarrhea indi-ces were measured:the rate of loose stools,diarrhea index,accumulated frequency of loose stools at differ-ent time points within 5 hours,and small intestine pro-pelling rate.Serum levels of TNF-α and IL-6 were de-tected by ELISA.Serum NO content was determined u-sing the Griess method.The activities of SOD and CAT,as well as MDA content in the ileum and colon,were measured.The pathological changes and the ex-pression of mRNA related to intestinal barrier proteins in the ileum and colon were evaluated using HE stai-ning and RT-qPCR.Results Allicin improved diar-rhea symptoms in mice induced by senna leaf.It re-duced the rate of loose stools,diarrhea index,cumula-tive number of loose stools in five hours,and the intes-tinal propulsion rate.Allicin also protected the intesti-nal mucosa,decreased serum TNF-α and IL-6 levels,and lowered MDA content in the intestines.It in-creased serum NO levels and enhanced SOD and CAT activities in the intestines.Additionally,allicin upreg-ulated the mRNA expression of AQP1,AQP4,and ZO-1 in intestinal tissues.Conclusions Allicin has a significant therapeutic effect on senna-induced diarrhea in mice.The underlying molecular mechanisms may involve anti-inflammatory and antioxidant effects,in-creased NO content,and upregulation of mRNA ex-pression of aquaporins and tight-junction proteins.

Objective:To investigate the effects of two anastomosis methods on perioperative and pathological outcomes during totally laparoscopic right hemicolectomy (TLRH).Methods:In a national multicenter snapshot study, 1,854 patients who underwent laparoscopic right hemicolectomy were enrolled from 52 tertiary hospitals across China. The post-hoc analysis based on this study compared the data of 303 patients who underwent TLRH. Patients were divided into the antiperistaltic group (33 cases) and the isoperistaltic group (270 cases) according to type of anastomosis. Due to the significant difference in sample size between the two groups, propensity score matching (PSM) was performed to eliminate the influence of baseline characteristic discrepancies. The matching was based on the following known confounding factors: age, gender, body mass index (BMI), history of abdominal surgery, and history of diabetes, with a caliper value of 0.2. Perioperative and pathological outcomes were compared between the two groups.Results:After PSM, 33 patients were included in the antiperistaltic group and 65 patients in the isoperistaltic group. There were no statistically significant differences in baseline data between the two groups (all P>0.05). No significant differences were observed between the two groups in terms of operation time, blood loss, time to first defecation, time to first oral intake, or the incidence and grading of complications either (all P>0.05). However, length of postoperative hospital stay in the isoperistaltic group was significantly shorter than that in the antiperistaltic group, however (7.0 [6.0, 9.0] days vs. 8.0 [7.0, 10.5] days, P=0.049). In terms of pathological outcomes, there were also no statistically significant differences between the two groups in the number of harvested lymph nodes or the number of positive lymph nodes (all P>0.05). Conclusions:The two digestive tract reconstruction modalities, antiperistaltic and isoperistaltic anastomosis, have comparable perioperative safety and efficacy in TLRH. The isoperistaltic group had better outcomes in terms of postoperative hospital stay.

Objective:To analyze the drug resistance status of Mycobacterium tuberculosis(MTB)at a hospital in Xiamen over the past decade. Methods:Sputum culture-positive specimens of tuberculosis patients from Xiamen Xinglin Hospital from 2015 to 2024 were collected retrospectively. Isolates were identified as MTB complex and subjected to drug susceptibility testing. Drug resistance patterns and trends over the study period were analyzed using descriptive statistics and Chi-square trend tests in SPSS 27.0 and GraphPad Prism 8.0.Results:Among 3 883 MTB isolates analyzed,1 132(29.15%)exhibited resistance to at least one drug. The highest rates of resistance to individual first-line drugs were observed for isoniazid(INH,16.04%),streptomycin(SM,15.43%),and rifampicin(RFP,12.28%). Multidrug-resistant tuberculosis(MDR-TB)was identified in 380 isolates(9.79%). The predominant MDR resistance patterns were INH+RFP+SM(2.34%),INH+RFP(1.65%),and INH+RFP+SM+ethambutol(EMB)(1.03%). Polyresistance was found in 188 isolates(4.84%),the predominant patterns were INH+SM(1.49%),INH+fluoroquinolone(FQs)(0.31%),and INH+para-aminosalicylic acid(PAS)(0.31%). Extensively drug-resistant tuberculosis(XDR-TB)was detected in 49 isolates(1.26%). From 2015 to 2024,significant decreasing trends were observed for overall drug resistance( χ2=8.858, P=0.003),MDR( χ2=15.692, P<0.001),and RFP resistance( χ2=21.627, P<0.001). In contrast,fluoroquinolone(FQs)resistance showed no significant trend( χ2=0.149, P=0.699). Among RFP resistant and MDR isolates,FQs resistance rates were notably high at 33.12%(158/477)and 36.84%(140/380),respectively. Conclusions:The MTB resistance situation in the hospital has gradually declined in the past 10 years,but the resistance situation remains severe,and clinical attention needs to be strengthened on the use of FQs.

Objective:To analyze the situation of rodents carrying Hantavirus and the genetic and evolutionary characteristics of the virus in Zibo city, Shandong province in 2022, and provide reference for the scientific prevention and control of hemorrhagic fever with renal syndrome (HFRS).Methods:Real-time quantitative PCR (RT-qPCR) was used to detect hantavirus (HV) nucleic acids in rodent lung tissues and identify HV genotypes. Each nucleic acid fragment was designed to amplify various gene fragments by segment, and the whole genome of Hantavirus was sequenced by second generation sequencing. Sequence assembly was performed using SeqMan 7.1.0.44, a subprogram of DNAStar. Sequence alignment and evolutionary analysis were conducted using MEGA 7.0 and BioEdit software.Results:A total of 270 host animals were captured in this survey. Among them, 13 rodent lung samples tested positive for Hantavirus, resulting in a virus-positive rate of 4.8%. The full-genome sequences of four hantavirus strains were successfully obtained, all identified as Seoul virus (SEOV) genotype. Four Hantavirus-positive samples showed high nucleotide sequence homology in the M gene and belonged to the SEOV S3 subtype. These strains exhibited high similarity with those from Hebei, Liaoning, and Beijing. The amino acid sequences of the nucleoprotein and glycoprotein immunogenic epitopes were identical to those of the vaccine strain Z37.Conclusions:This study successfully determined the full genome sequences of four hantavirus strains from Zibo city, Shandong province. The genotypes are primarily SEOV, with the subtype being S3. The homology of genes within the same subtype is high, with no significant variations observed. The alignment of immune epitopes in key proteins suggests that the current vaccine may provide protection against locally circulating strains, but further in-depth research is still required.

BACKGROUND: PANoptosis has the features of pyroptosis, apoptosis, and necroptosis. Numerous studies have confirmed the diverse roles of various types of cell death in acute liver failure (ALF), but limited attention has been given to the crosstalk among them. In this study, we aimed to explore the role of PANoptosis in ALF and uncover new targets for its prevention or treatment. METHODS: Three ALF-related datasets (GSE14668, GSE62029, and GSE74000) were downloaded from the Gene Expression Omnibus (GEO) database to identify differentially expressed genes (DEGs). Hub genes were identified through intersecting DEGs, genes obtained from weighted gene co-expression network analysis (WGCNA), and genes related to PANoptosis. Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), protein‒protein interaction (PPI) analyses and gene set enrichment analysis (GSEA) were performed to determine functional roles. Verification was performed using an ALF mouse model. RESULTS: Our results showed that expression of seven hub genes (B-cell lymphoma-2-modifying factor (BMF), B-cell lymphoma-2-interacting protein 3-like (BNIP3L), Caspase-1 (CASP1), receptor-interacting protein kinase 3 (RIPK3), uveal autoantigen with coiled-coil domains and ankyrin repeats protein (UACA), uncoordinated-5 homolog B receptor (UNC5B), and Z-DNA-binding protein 1 (ZBP1)) was up-regulated in liver samples of patients. However, in the ALF mouse model, the expression of BNIP3L, RIPK3, phosphorylated RIPK3 (P-RIPK3), UACA, and cleaved caspase-1 was up-regulated, while the expression of CASP1 and UNC5B was down-regulated. The expression of ZBP1 and BMF increased only during the development of ALF, and there was no significant change in the end stage. Immunofluorescence of mouse liver tissue showed that macrophages expressed all seven markers. Western blot results showed that pyroptosis, apoptosis, and necroptosis were always involved in lipopolysaccharide (LPS)/ d-galactosamine (d-gal)-induced ALF mice. The ALF cell model showed that bone marrow-derived macrophages (BMDMs) form PANoptosomes after LPS stimulation. CONCLUSIONS: Our results suggest that PANoptosis of macrophages promotes the development of ALF. The seven new ALF biomarkers identified and validated in this study may contribute to further investigation of diagnostic markers or novel therapeutic targets of ALF.
