Background:
and Purpose This study aimed to investigate the association between residual inflammatory risk (RIR) and vulnerable plaques using high-resolution magnetic resonance imaging (HRMRI) in symptomatic intracranial atherosclerotic stenosis (ICAS).
Methods:
This retrospective study included 70%–99% symptomatic ICAS patients hospitalized from January 2016 to December 2022. Patients were classified into four groups based on high-sensitivity C-reactive protein (hs-CRP) and low-density lipoprotein cholesterol (LDL-C): residual cholesterol inflammatory risk (RCIR, hs-CRP ≥3 mg/L and LDL-C ≥2.6 mmol/L), RIR (hs-CRP ≥3 mg/L and LDL-C <2.6 mmol/L), residual cholesterol risk (RCR, hs-CRP <3 mg/L and LDL-C ≥2.6 mmol/L), and no residual risk (NRR, hs-CRP <3 mg/L and LDL-C <2.6 mmol/L). Vulnerable plaque features on HRMRI included positive remodeling, diffuse distribution, intraplaque hemorrhage, and strong enhancement.
Results:
Among 336 included patients, 21, 60, 58, and 197 were assigned to the RCIR, RIR, RCR, and NRR groups, respectively. Patients with RCIR (adjusted odds ratio [aOR], 3.606; 95% confidence interval [CI], 1.346–9.662; P=0.011) and RIR (aOR, 3.361; 95% CI, 1.774–6.368, P<0.001) had higher risks of strong enhancement than those with NRR. Additionally, patients with RCIR (aOR, 2.965; 95% CI, 1.060–8.297; P=0.038) were more likely to have intraplaque hemorrhage compared with those with NRR. In the sensitivity analysis, RCR (aOR, 2.595; 95% CI, 1.201–5.608; P=0.015) exhibited an additional correlation with an increased risk of intraplaque hemorrhage.
Conclusion
In patients with symptomatic ICAS, RIR is associated with a higher risk of intraplaque hemorrhage and strong enhancement, indicating an increased vulnerability to atherosclerotic plaques.

Background:
s/Aims: Sarcomatoid hepatocellular carcinoma (HCC) is a rare histological subtype of HCC characterized by extremely poor prognosis; however, its molecular characterization has not been elucidated.
Methods:
In this study, we conducted an integrated multiomics study of whole-exome sequencing, RNA-seq, spatial transcriptome, and immunohistochemical analyses of 28 paired sarcomatoid tumor components and conventional HCC components from 10 patients with sarcomatoid HCC, in order to identify frequently altered genes, infer the tumor subclonal architectures, track the genomic evolution, and delineate the transcriptional characteristics of sarcomatoid HCCs.
Results:
Our results showed that the sarcomatoid HCCs had poor prognosis. The sarcomatoid tumor components and the conventional HCC components were derived from common ancestors, mostly accessing similar mutational processes. Clonal phylogenies demonstrated branched tumor evolution during sarcomatoid HCC development and progression. TP53 mutation commonly occurred at tumor initiation, whereas ARID2 mutation often occurred later. Transcriptome analyses revealed the epithelial–mesenchymal transition (EMT) and hypoxic phenotype in sarcomatoid tumor components, which were confirmed by immunohistochemical staining. Moreover, we identified ARID2 mutations in 70% (7/10) of patients with sarcomatoid HCC but only 1–5% of patients with non-sarcomatoid HCC. Biofunctional investigations revealed that inactivating mutation of ARID2 contributes to HCC growth and metastasis and induces EMT in a hypoxic microenvironment.
Conclusions
We offer a comprehensive description of the molecular basis for sarcomatoid HCC, and identify genomic alteration (ARID2 mutation) together with the tumor microenvironment (hypoxic microenvironment), that may contribute to the formation of the sarcomatoid tumor component through EMT, leading to sarcomatoid HCC development and progression.

Objective To investigate the effects of CYP2C9 and VKORC1 gene polymorphism on warfarin stable dose and myocardial injury in patients after heart valve replacement in Qiandongnan region.Methods Clinical data of 110 patients in Qi-andongnan who underwent heart valve surgery at Guizhou Medical University's Second Affiliated Hospital's Cardiothoracic De-partment(form November 2019 to October 2024)were collected.According to CYP2C9*3 genotype,patients were divided into wild type(AA type)and mutant type(AC type and CC type),and VKORC1-1639G>A genotype was divided into wild type(GG type)and mutant type(GA type and AA type).Levene variance homogeneity test was performed first to compare warfarin dose between different genotypes and INRcompliance timebetween groups.The factors affecting the stable dose of warfarin werean-alyzed by hierarchical regression.BP neural network model is used for risk prediction.Generalized linear mixed effects model(GLMMs)was used to analyze the relationship between CYP2C9 and VKORC1 gene status and postoperative myocardial inju-ry.Results The distribution of all genes was consistent with Hardy-Weinberg genetic balance(both P>0.05).CYP2C9*3 and VKORC1-1639G>A gene status were significantly different from atrial fibrillation,myocardial injury,thrombosis and hemor-rhage,and combined drugs(amiodarone,rifampicin,phenobarbital,voriconazole)(all P<0.05).The compliance rate(TTR)and warfarin stable dose of warfarin anticoagulation therapy for CYP2C9*3 genotype AA were significantly higher than that of genotype AC(both P<0.01),and the INR compliance time was significantly lower than that of genotype AC(both P<0.01).The warfarin stable dose and INR reach time of VKORC1-1639G>A genotype GG+GA were significantly higher than geno-type AA(both P<0.01),and TTR was significantly lower than genotype AA(both P<0.01).Stratified regression analysis showed that CYP2C9,VKORC1,age,amiodarone,BSA,BMI and gender had significant effects on warfarin stable dose(all P<0.05).BP neural network model construction showed that CYP2C9 and VKORC1 had the highest contribution to model classifi-cation,followed by amiodarone,BSA,BMI,gender and age.The model verification results showed that the accuracy was 93.54%,the sensitivity and specificity were 85.62%and 95.89%,respectively.The positive predictive value was 94.23%,the negative predictivevaluewas 93.15%,and the ROC AUC fitting of thepredictionmodelwas 0.958.The levels of cTnI,CK-MB and hs-CRP in CYP2C9*3 and VKORC1-1639G>A mutant patients were significantly higher than those in wild-type patients(P<0.05).GLMMs model analysis showed that CYP2C9 and VKORC1 gene mutations were still statistically associated with the risk of postoperative myocardial injury regardless of adjustment factors(P<0.01).Conclusion The CYP2C9 * 3 and VKORC1-1639G>A gene polymorphisms in patients who underwent heart valve replacement surgery in Qiandongnan area sig-nificantly affect the stable dose of warfarin and the rate of achieving anticoagulation targets.Moreover,the mutant genes are closely related to the increase in postoperative myocardial injury indicators and the increased risk.

Salmonella enterica serovar Goldcoast isolates from Yangzhou were analyzed for assessment of their pathogenic and ge-nomic characteristics.From 2017 to 2023,eight strains were detected through foodborne disease surveillance and health check-ups.These strains exhibited resistance to two to seven antibiotic classes,and all strains bore a T57S mutation in the parC gene.Notably,50%(4/8)of the strains carried sulfonamide resistance genes(sul1 or sul3),and 37.5%(3/8)were positive for extended-spectrum beta-lactamase(ESBL)genes,including blaCTX-M-55 and blaTEM-1.Multilocus sequence typing(MLST)revealed that ST358(five strains)and ST2529(three strains)were the predominant sequence types,corresponding to CRISPR Ⅰ and Ⅱ groups,respectively.Single nucleotide polymorphism(SNP)phylogenetic analysis indicated a close genetic relationship between the case isolate Sal-2214 and strains from multiple regions,with a SNP difference≤20,thus suggesting potential inter-regional transmission.For example,one isolate from the stool of a 4-year-old child with diarrhea(Sal-2214)carried the beta-lactam resistance gene(blaCTX-M-55)and exhib-ited high resistance to cefotaxime(CTX)and ceftazidime(CAZ).These findings indicated that S.enterica Goldcoast emerged in Yang-zhou from 2022,and was characterized by multidrug resistance and a genetic relationship with strains from coastal regions.These find-ings highlight the need for enhanced resistance monitoring and trace-back studies to better understand the epidemiology and control the potential spread of this pathogen.
