Objective: To investigate the detection of natural infection with pathogens in rodents in Huzhou City, Zhejiang Province, so as to provide a basis for risk assessment and control of rodent-borne diseases. Methods: From August to September each year during the period of 2022-2024, urban residential areas, rural residential areas, key industries, farmland and cultivated land, forests, and shrublands in various counties (districts) of Huzhou City were selected as rodent surveillance sites. Rodents were captured using the trap night method. Following anesthesia, the rodents were euthanized by cervical dislocation. Species were identified based on morphological characteristics. Under sterile conditions, dissection was performed to collect liver, spleen, lung, and kidney tissues. These tissues were then mixed together, and detected for Hantavirus, Dabie bandavirus, Leptospira, and Orientia tsutsugamushi using fluorescence quantitative PCR. The detection rates of these natural infections with pathogens were analyzed across different rodent species, counties (districts), and habitats. Results: A total of 259 rodents were captured from 2022 to 2024, including Rattus norvegicus, Rattus tanezumi, Suncus murinus, Mus musculus, Leopoldamys edwardsi, Niviventer fulvescens, Rattus losea, and Apodemus agrarius. The dominant species were Rattus norvegicus (142 individuals) and Rattus tanezumi (59 individuals), collectively accounting for 77.61%. With the exception of Orientia tsutsugamushi, Hantavirus, Dabie bandavirus, and Leptospira were all detected, with detection rates of 5.02%, 1.93%, and 10.42%, respectively. Hantavirus and Leptospira were simultaneously detected in one Rattus norvegicus, yielding a mixed infection rate of 0.39%. The three pathogens were detected in rodents in Wuxing District, Nanxun District, Deqing County, Changxing County, and Anji County, with detection rates of 6.45%, 5.71%, 26.32%, 4.76%, and 24.00%, respectively. They were also detected in rodents in urban residential areas, rural residential areas, key industries, farmland, and forests, with detection rates of 28.57%, 21.57%, 10.91%, 12.50%, and 14.81%, respectively. Notably, all three pathogens were simultaneously detected in Rattus norvegicus, Rattus tanezumi, rural residential areas, and key industries. Conclusions Rattus norvegicus and Rattus tanezumi were identified as the dominant rodent species in Huzhou City. The detection of Hantavirus, Dabie bandavirus, and Leptospira, including instances of mixed infection. It is necessary to enhance surveillance and control measures targeting these key species and high-risk habitats.

Objective:To investigate the expression of heterogeneous nuclear ribonucleoprotein A2B1 (HNRNPA2B1) in human esophageal cancer tissues and its clinical significance.Methods:Single-cell data for esophageal cancer were downloaded from the Gene Expression Omnibus (GEO) database (GSE160269 dataset, last updated on November 29, 2020) to analyze the expression of HNRNPA2B1. Transcriptional sequencing data for esophageal cancer from The Cancer Genome Atlas (TCGA) database, including the fragments per kilobase of transcript per million mapped reads (FPKM) quantitative data (173 samples, consisting of 162 esophageal cancer tissues and 11 adjacent normal tissues), and survival data in the phenotype category were downloaded. Analysis of FPKM quantitative data from the TCGA database for esophageal cancer was performed. The top 250 genes most correlated with HNRNPA2B1 were selected and the R4.3.0 clusterProfiler package was used to conduct Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses on the selected gene set. FPKM quantitative data from the TCGA database for esophageal cancer were imported into the CIBERSORTx website to obtain immune cell abundance scores, and the correlation between HNRNPA2B1 and the degree of immune cell infiltration was analyzed. The clinicopathological data of patients from esophageal cancer tissue microarrays including 114 cases of esophageal squamous cell carcinoma tissues and 66 cases of adjacent normal tissues were collected. The patients underwent surgery from January 2006 to December 2008, and the follow-up period extended until July 2015. Cytokeratin (CK) and HNRNPA2B1 expression in esophageal cancer tissue microarrays were detected by using multi-color immunohistochemical (mIHC) staining, and multispectral tissue imaging was conducted. The R4.3.0 survival package and survminer package in TCGA database were used to calculate the optimal cut-off value of HNRNPA2B1 expression and the proportion of CK + HNRNPA2B1 + cells in tissue microarrays was used to calculate the cut-off value of HNRNPA2B1 expression based on which patients were categorized into high and low expression groups. The overall survival (OS) of both groups was compared and the factors influencing OS were analyzed by using the Cox proportional hazards model. Results:In the GSE160269 dataset of single-cell data for esophageal cancer, the expression level of HNRNPA2B1 in tumor epithelial cells was higher than that in normal epithelial cells, and HNRNPA2B1 was highly expressed in various immune cell subtypes. The high expression level of HNRNPA2B1 was positively correlated with regulatory T cells, naive B cells and memory CD4 + T cells. GO enrichment analysis revealed that HNRNPA2B1 was primarily involved in the biological process of nuclear division, cellular components were mainly enriched in chromosomal regions, and molecular functions were mainly enriched in ATP hydrolysis activity. KEGG enrichment analysis indicated that HNRNPA2B1 was primarily involved in biological processes such as the cell cycle, spliceosome, and DNA replication. Results from mIHC and multispectral tissue imaging demonstrated that CK was predominantly expressed in the cell membranes of tumor cells and normal esophageal epithelial cells, while HNRNPA2B1 was primarily expressed in the nuclei of tumor cells and normal esophageal cells. The expression level of HNRNPA2B1 in esophageal cancer tissues was higher than that in the normal paracancerous tissues ( U = 2 984.00, P < 0.05). Results of tissue microarrays and the survival analysis on the data in the TCGA database indicated that esophageal cancer patients with low HNRNPA2B1 expression had a better OS compared to those with high expression (both P < 0.05). Cox multivariate regression analysis revealed that age ( HR = 1.919, 95% CI: 1.158-3.182, P = 0.011), TNM stage ( HR = 2.404, 95% CI: 1.374-4.207, P = 0.002), T stage ( HR = 2.349, 95% CI: 1.150-4.789, P = 0.019), and the expression of HNRNPA2B1 in tumor epithelial cells ( HR = 2.160, 95% CI: 1.280-3.647, P = 0.004) were independent factors influencing OS in esophageal cancer patients. Conclusions:The high expression of HNRNPA2B1 protein in esophageal cancer tissues may play a role in the developement and progression of esophageal cancer, serving as a crucial biological indicator for prognostic assessment of esophageal cancer.

AIM:To investigate whether the expression of perilipin 2(PLIN2)in renal tubular cells could predict a decline in renal function in diabetic kidney disease(DKD)patients,and to explore the potential mechanisms in-volved in renal tubular cell injury induced by PLIN2 during the progression of DKD.METHODS:Control individuals(n=12)and DKD patients(n=51)were enrolled in this retrospective cohort study.Demographic and laboratory data were col-lected.A simplified linear mixed-effects model was applied to assess the estimated glomerular filtration rate(eGFR)slope.The relationship between PLIN2 and renal function decline in DKD patients was predicted by Spearman correlation analysis and a generalized linear model.BKS-db/db diabetic mice and streptozotocin-induced diabetic mice were used.Primary renal tubular cells were treated with glucose and transfected with small interfering RNA or plasmid.Western blot-ting and immunofluorescence staining were used to detect PLIN2 expression.Lipid droplets were stained with oil red O.The oxygen consumption rate(OCR)of mitochondria was measured using an extracellular flux analyser.RESULTS:The expression of PLIN2 was markedly higher in the tubules of DKD patients than in those of control subjects.After 24(12,39)months of follow-up,the eGFR slope of DKD patients was-7.42(-19.77,-2.09)mL/(min·1.73 m2·year).An in-crease in the baseline percentage of PLIN2-positive tubules was significantly associated with the eGFR slope during the fol-low-up period[hazard ratio(HR)=1.90,95%confidence interval(CI):1.00～3.58],indicating that tubular PLIN2 could predict a decrease in renal function in DKD patients.Both the accumulation of lipid droplets and the expression of PLIN2 were markedly greater in the tubules of diabetic mice than in those of control mice.Glucose treatment induced lipid droplet accumulation and PLIN2 expression in renal tubular cells.Knockdown of PLIN2 significantly alleviated glucose-in-duced lipid droplet accumulation,whereas PLIN2 overexpression aggravated glucose-induced lipid droplet accumulation.The decrease in mitochondrial OCR in renal tubular cells induced by glucose treatment was alleviated after PLIN2 knock-down.However,overexpression of PLIN2 directly decreased the mitochondrial OCR.CONCLUSION:The PLIN2 ex-pression in tubules predicts a decline in renal function in patients with DKD.The PLIN2 suppresses mitochondrial aerobic respiration and contributes to the accumulation of lipid droplets in renal tubular cells to promote the progression of DKD.

Objective To discuss the feasibility and safety of simultaneous bilateral adrenal vein sampling(AVS)using two 4F-MPA1 catheters via right elbow vein access.Methods A total of 51 consecutive patients with primary aldosteronism,who received simultaneous bilateral AVS using two 4F-MPA1 catheters(one of the two catheters was shaped into pig tail figure)via right elbow vein access at Xiangyang Municipal Central Hospital between October 2021 and October 2022,were enrolled in this study.The used catheter,the success rate of simultaneous bilateral AVS,and the incidence of complications rate were calculated.Results The 4F-MPA1 catheter was used for all of the right AVS,while a specially shaped 4F-MPA1 catheter was used for the main trunk vein AVS of the left adrenal gland and the central vein AVS of the left adrenal gland.The success rate of simultaneous bilateral AVS was 92.2%(47/51).Adrenal hematoma occurred in one patient(1.96%).Conclusion The technique of simultaneous bilateral AVS using two 4F-MPA1 catheters via right elbow vein access is simple to operate,less traumatic,and clinically safe and feasible.However,due to the small sample used in this study,the clinical value of this technique still needs further investigation and verification.

Objective To investigate the application of transesophageal echocardiography in the evaluation of left atrial ear volume and function changes in patients with patent foramen ovale and atrial fibrillation. Methods Eighty patients with patent foramen ovale were selected as the study objects, and were divided into atrial fibrillation group (n=44) and non-atrial fibrillation group (n=36), and 30 healthy subjects were selected as control group. Transesophageal echocardiography was performed in three groups. The left atrial appendage volume and changes of function in three groups were compared. Results The left atrial appendage maximum volume (LAAV_max), left atrial appendage minimum volume (LAAV_min), left atrial appendage opening maximum area (MA) and left atrial appendage opening maximum length diameter (MD) in the atrial fibrillation group and non-atrial fibrillation group were significantly higher, and the left atrial appendage maximum emptying velocity (LAAeV) and left atrial appendage maximum filling velocity (LAAfV) were significantly lower than those of the control group (P < 0.05). The LAAV_max, LAAV_min as well as MA and MD of left auricular opening in patients with left auricular spontaneous imaging (SEC) in the atrial fibrillation group were significantly higher than those in the non-atrial fibrillation group, and LAAeV and LAAfV were significantly lower than those in the non-atrial fibrillation group (P < 0.05). After treatment, the incidence of end-point events in the atrial fibrillation was significantly higher than that in the non-atrial fibrillation group (P < 0.05). Conclusion The application of transesophageal echocardiography in the evaluation of left atrial ear volume and function changes in patients with patent foramen ovale and atrial fibrillation is effective. The left atrial appendage function of patients with atrial fibrillation is worse than that of patients without atrial fibrillation.

AIM: To observe the effects of Tangshen formula (TSF) treatment on lipid efflux and uptake in sodium palmitate (PA) induced RAW264.7 macrophages. METHODS: After 200 μmol/L PA induced RAW264.7 macrophages, TSF and PGC-1α-siRNA were given to intervene respectively. The lipid content in the cells was detected by ELISA kit; intracellular lipid droplet deposition was detected by BODIPY 493/503 and Filipin staining. Western blot and Real-time PCR were used to detect the expression of PGC-1α, LXR, ABCA1 and CD36. RESULTS: TSF diminished the levels of TC, TG and intracellular lipid droplet deposition in PA-induced RAW264.7 macrophages. Western blot and Real-time PCR analysis showed that TSF could up-regulate the expression of PGC-1α, LXR, ABCA1 and down-regulate the expression of CD36. Furthermore, silencing PCG-1α by SiRNA significantly suppressed the effects of upregulating the expression of PGC-1α, LXR and ABCA1, and downregulating the CD36 expression with TSF treatment. CONCLUSION: TSF may extenuate intracellular lipid droplet deposition in macrophages by upregulating cholesterol efflux through activating the PGC-1α/LXR/ABCA1 pathway and inhibiting lipid uptake through down-regulateing the expression of CD36.

ObjectiveTo analyze the coping style and its relationship with anxiety status among middle school students aged 13 to 18 in Anhui province during the COVID-19 epidemic. MethodsFrom February 13 to 19， 2020， a cross-sectional survey was conducted among middle school students in Anhui province by using convenience sampling method and network questionnaire. The assessment tools included the Coping Style Scale for Middle School Students （CSSMSS） and the Screen for Child Anxiety Related Emotional Disorders （SCARED）. ResultsThe results of the CSSMSS evaluation showed that female students scored higher in emotion abreaction than male students ［（8.27±2.98） vs. （7.84±2.91）］. The scores of tolerance ［（9.74±2.73） vs. （9.11±2.60）］， escape ［（7.82±2.79） vs. （7.26±2.44）］， emotion abreaction ［（8.48±2.97） vs. （7.91±2.93）］ and fantasy/denial ［（9.79±3.56） vs. （9.26±3.47）］ of senior high school students were higher than those of junior high school students， and the score of problem solving ［（19.38±4.07） vs. （20.33±4.54）］ was lower than that of junior high school students， with statistical significance （P<0.05 or 0.01）. Correlation analysis results showed that the scores of tolerance， escape， emotion abreaction and fantasy/deny in CSSMSS were positively correlated with the scores of SCARED of middle school students in Anhui province （r=0.348， 0.287， 0.390， 0.501， P<0.01）. ConclusionDuring COVID-19 epidemic， students of different genders and grades in Anhui province have different coping styles， and some coping styles may induce anxiety status.

Four hundred and four male patients with primary gout were enrolled. According to the degree of nonalcoholic fatty liver diseases (NAFLD), the patients were divided into simple gout ( n=121), gout combined with mild NAFLD ( n=149) and gout combined with moderate-severe NAFLD ( n=134). The height, weight, waist, hip, blood pressure and blood biochemistry parameters of patients were measured. The degree of NAFLD was negatively correlated with the age of patients in three groups. The BMI, ratio of waist/hip, count of red cells, hemoglobin, hematocrit, red blood cell distribution width ( SD and CV), triglyceride, alanine aminotransferase and HOMA-IR were increased with the increasing of NAFLD severity (all P<0.05). Red blood cell count, hemoglobin, alanine aminotransferase, serum uric acid increased with the increasing of NAFLD severity (all P<0.05). Platelet, serum urea nitrogen and serum creatinine were decreased with the increase of NAFLD severity. Logistic regression showed that BMI, hemoglobin and HOMA-IR were independent risk factors for NAFLD. The prevalence and the severity of NAFLD was increased with increasing quadrates of hemoglobin. Taking group Q1 as a control, OR of NAFLD in group Q2 was 1.166(95 %CI:0.638-2.133), OR in group Q3 was 2.011(95 %CI:1.122-3.605)and OR in group Q4 was 3.120(95 %CI:1.613-6.034). The result indicates that hemoglobin levels are associated with the development and the severity of NAFLD in male patients with primary gout.
