Objective To describe and analyze the epidemiological characteristics of scrub typhus in Huai'an, Jiangsu Province from 2006 to 2024 and explore the long-term incidence trend and distribution of high-risk areas, and to formulate targeted prevention and control strategies. Methods The scrub typhus case report data of Huai'an from 2006 to 2024 in the Chinese Disease Prevention and Control Information System were extracted for descriptive analysis. Results A total of 898 cases of scrub typhus were reported in Huai'an, with an average annual incidence rate of 0.96 per 100 000 from 2006 to 2024. There was a turning point in the incidence trend of scrub typhus in 2011. From 2006 to 2011, the annual percentage change (APC) was 47.09% (95% CI: 7.53 - 859.39), and the upward trend was statistically significant (P < 0.05). From 2012 to 2024, the APC was -2.12% (95% CI: -29.09 - 3.75), and the downward trend was not statistically significant. October and November were the high-incidence months, and the total concentration from 2006 to 2024 was 0.93, indicating that scrub typhus had strict seasonality. The circular distribution method estimated that the peak period of the epidemic was from October 11th to November 25th, and the peak day of incidence was November 3rd. Jinhu County was a high-incidence area. The ratio of male to female cases was 1.03. The age group with the highest reported incidence was 40 to < 80 years old. The occupation with the highest proportion was farmers, accounting for 78.03%. Conclusion From 2006 to 2024, scrub typhus in Huai'an shows a peak every 3 - 4 years. Middle-aged and elderly farmers are the key population at risk, and Jinhu County is a key area. In the future, targeted health education should be carried out to effectively control the prevalence of scrub typhus.

This research investigated the impact of Ganoderma lucidum polysaccharides(GLP) on hepatoblastoma HepG2 and Huh6 cell models, as well as KM mouse model with in situ transplanted tumors, so as to provide a theoretical basis for the clinical application of GLP. Cell viability was assessed through the CCK-8 assay, whereas cell proliferation was evaluated by using the BeyoClick~(TM)EdU-488 test. Cell apoptosis was visualized via Hochest 33258 staining, and autophagy was detected through Mrfp-GFP-LC3 dual fluorescence staining. An in situ tumor transplantation model was created by using HepG2 cells in mice, and mice were treated with normal saline and GLP of 100, 200, and 300 mg·kg~(-1) for tumor count calculation and size assessment. Hematoxylin-eosin(HE) staining was used to observe pathological changes in tumor tissue and vital organs(liver, kidney, lung, spleen, and heart). Western blot analysis was conducted to measure the protein expressions of tumor protein P53(P53), B-cell lymphoma-2(Bcl-2), Bcl-2-associated X protein(Bax), cleaved-caspase-3, Beclin-1, autophagy related protein-5(Atg-5), microtubule-associated protein-light chain-3Ⅰ(LC3Ⅰ)/LC3Ⅱ, autophagy adapter protein 62(P62), protein kinase B(Akt), p-Akt, mammalian target of rapamycin(mTOR), and p-mTOR. The in vitro experiment revealed that compared with the control group, after GLP treatment, tumor cell viability decreased significantly; apoptosis rate increased in a dose-dependent manner, and autophagic flux was inhibited. The in vivo experiments showed that compared with the model group, mice treated with GLP exhibited significantly fewer and smaller tumors. Western blot results showed that compared with the control group or model group, levels of P53, Bax, cleaved-caspase-3, Beclin-1, Atg-5, and LC3-Ⅱ/LC3-Ⅰ were significantly increased after GLP treatment, and the levels of Bcl-2, P62, p-Akt/Akt, and p-mTOR/mTOR were significantly decreased. These outcomes suggest that GLP promotes apoptosis and autophagy in hepatoblastoma cells by regulating the Akt/mTOR pathway.

OBJECTIVES: To develop and validate a preoperative clinical-radiomics model for predicting overall survival (OS) and disease-free survival (DFS) in patients with extrahepatic cholangiocarcinoma (eCCA) undergoing radical resection. METHODS: In this retrospective study, consecutive patients with pathologically-confirmed eCCA who underwent radical resection at our institution from 2015 to 2022 were included. The patients were divided into a training cohort and a validation cohort according to the chronological order of their CT examinations. Least absolute shrinkage and selection operator (LASSO)-Cox regression was employed to select predictive radiomic features and clinical variables. The selected features and variables were incorporated into a Cox regression model. Model performance for 1-year OS and DFS prediction was assessed using calibration curves, area under receiver operating characteristic curve (AUC), and concordance index (C-index). RESULTS: This study included 123 patients (mean age 64.0 ± 8.4 years, 85 males/38 females), with 86 in the training cohort and 37 in the validation cohort. The OS-predicting model included four clinical variables and four radiomic features. It achieved a training cohort AUC of 0.858 (C-index = 0.800) and a validation cohort AUC of 0.649 (C-index = 0.605). The DFS-predicting model included four clinical variables and four other radiomic features. It achieved a training cohort AUC of 0.830 (C-index = 0.760) and a validation cohort AUC of 0.717 (C-index = 0.616). CONCLUSIONS The preoperative clinical-radiomics models show promise as a tool for predicting 1-year OS and DFS in eCCA patients after radical surgery.

A novel analytical method was developed in this study by combining online solid phase extraction with ultra performance liquid chromatography-tandem mass spectrometry(Online SPE-UPLC-MS/MS)for simultaneous determination of 50 kinds of steroid hormones in surface water.Specifically,after high-speed centrifugation of 4 mL water samples,the supernatant was directly injected into an Oasis HLB online SPE column for enrichment and purification.Subsequently,the target compounds were transferred to the analytical column via valve switching for separation and analysis.The chromatographic separation was performed on a Thermo Acclaim RSLC C18 column(100 mm×2.1 mm,2.2 μm),using a mobile phase composed of 5 mmol/L ammonium fluoride aqueous solution and acetonitrile.Mass spectrometric detection was conducted in positive ion mode,utilizing multiple reaction monitoring(MRM)with quantification achieved by the internal standard method.The method validation demonstrated that the limits of detection(LOD)for the 50 kinds of steroid hormones ranged from 0.02 to 0.50 ng/L,while the limits of quantification(LOQ)were between 0.08 and 1.67 ng/L.The average recoveries in surface water samples at spiked concentrations of 5,20 and 200 ng/L were between 74.1％and 119％,with relative standard deviations(RSDs)of 0.2％to 9.9％.This method was applied to analyze 11 surface water samples collected from sites surrounding a pharmaceutical and chemical industrial park.A total of 44 kinds of steroid hormones were detected,with concentrations ranging from 0.11 to 88.6 ng/L,revealing the presence of hormone contamination in the environmental waters surrounding industrial areas.Compared with the traditional offline SPE methods,the proposed online SPE technique significantly reduced sample volume requirements and pretreatment time,while minimizing the loss of target compounds during the pretreatment process.Moreover,compared to reported online SPE techniques,this method achieved high-throughput analysis of multiple classes of steroid hormones,with lower detection limits and higher recoveries.Overall,this method provided rapid sample preparation,high sensitivity,and excellent stability,making it suitable for the direct analysis of trace steroid hormones in surface water.

Good endometrial receptivity is an essential factor for embryo implantation,and gene expression in endometrial tissue during the window of implantation(WOI)is closely related to receptivity.Transcriptome sequencing technology enables the identification of gene expression profiles of endometrium during different menstrual phases,as well as microRNAs and long-chain non-coding RNA sequences involved in regulating gene expression.Combining this technology with bioinformatics analysis provides a better understanding of specific gene expression during the receptive period and offers technical support for studying its regulatory mechanism.Moreover,gene expression profiles of the endometrium during different menstrual phases hold significant clinical application value for accurately assessing endometrium receptivity in infertility patients and those with repeated implantation failure,thereby guiding individualized embryo transfer strategies.This review summarizes the progress of transcriptome sequencing in evaluating human endometrial receptivity and discusses future research directions.This review aims to understand the complex molecular mechanisms of endometrial receptivity formation and regulation from the transcriptional level,in order to improve the implantation rate of embryos in assisted reproductive technology and reduce the abortion rate.

Objective To analysis the effectiveness and cost of Internet-based anticoagulation clinic versus traditional anticoagulation clinic treatment at Nanjing Drum Tower Hospital during the COVID-19 pandemic.Methods We reviewed and analyzed the clinical data of patients receiving anticoagulation management through Internet-based outpatient care and traditional outpatient care in Nanjing Drum Tower Hospital,from June 1,2020 to June 30,2021.Variability in time in therapeutic range(TTR)and international normalized ratio(INR)were calculated for enrolled patients.Patients meeting TTR&ge;60%and INR variability<0.65 were considered optimal anticoagulation quality.Cost-effectiveness analysis was conducted from the patients'perspective,with results expressed using the incremental cost-effectiveness ratio(ICER).Results In the"Internet-based anticoagulation outpatient care"and"traditional face-to-face anticoagulation outpatient care"groups,19 individuals(67.86%)and 67 individuals(76.14%)met the criteria for optimal anticoagulation quality,respectively.The mean TTR was(71.83±19.17)%in the Internet-based group and(71.74±23.41)%in the traditional face-to-face group,indicating similar levels of warfarin anticoagulation quality between the two groups.The ICER was calculated as 327.17 yuan,less than the per capita gross domestic product(GDP)of 2021.Conclusion During the COVID-19 pandemic,Nanjing Drum Tower Hospital's Internet-based anticoagulation outpatient care effectively complemented the government's epidemic control policies.It ensured equivalent anticoagulation outcomes and significantly reduced patients'financial burdens.This approach offers new insights and guidance for optimizing healthcare services in the post-pandemic era.

Objective To compare screw versus Kirschner wire fixation in the treatment of lateral humeral condyle frac-tures in children.Methods A systematic search was conducted in PubMed,Embase,the Cochrane library,Web of Science,China National Knowledge Internet(CNKI),Wanfang Datebase from in ception to February 2022.Studies comparing screws and Kirschner wire fixation in the treatment of lateral humeral condyle fractures in children were included.Outcome measures included and excluded by a set of inclusion and exclusion criteria and evaluated for their quality,their excellent and good rate of fracture healing,malunion,delayed union or nonunion,infection,limitation of elbow flexion or extension(＞10°)were ex-tracted and analyzed using software Rev Man 5.3.Results A total of 9 retrospective studies involving 647 patients were includ-ed,with 255 patients in the screw fixation group(including screw combined with Kirschner wire)and 392 patients in the Kirschner wire fixation group.Meta analysis showed the following:infection rate in the screw group was significantly lower than that in the Kirschner wire group[OR=0.22,95％CI(0.09,0.56),P=0.001].There were no significant differences between the 2 groups in excellent and good rate of fracture healing,malunion rate(P＞0.05).Subgroup analysis showed that infection rate in the screw-only group was significantly lower than that in the Kirschner wire group[OR=0.18,95％CI(0.05,0.65),P=0.009].Conclusion For lateral humeral condyle fractures,Screw fixation alone had a lower infection rate than kirschner wire fixation and screw combined with Kirschner wire fixation.There were no significant differences in the excellent and good rate of fracture healing,malunion.In terms of postoperative efficacy and safety of internal fixation,orthopaedic surgeons are more like-ly to recommend screws for fixation of lateral humeral condyle fractures in children.

Intestinal microorganisms and their metabolites are involved in the pathogenesis and progression of various cardiovascular diseases,especially in the progression of heart failure.This paper mainly discussed the gut microbial metabolites trimethylamine oxide(TMAO)participated in the pathological process of heart failure,and application value of TMAO in heart failure patients.This paper introduced the change characteristics of intestinal flora and its metabolites in heart failure patients,illu-minated the TMAO-mediated inflammatory response,and the related signal pathways and mechanism of myocardial hypertrophy and heart failure.High levels of TMAO are associated with poor outcomes in patients with heart failure indicating a good predictive value for the prognosis of heart failure.Regulating TMAO levels through diet,probiotics and prebiotics,antibiotics,fecal transplan-tation,and other pathways is expected to be a potential treatment for heart failure.

Objective To analyze the current situation and characteristics of risk factors in antithrombotic therapy(in-cluding antiplatelet and anticoagulant treatments)at home and abroad,and to provide a theoretical basis for the prevention and treatment of thrombosis or bleeding associated with antithrombotic therapy.Methods The literature on risk factors of an-tithrombotic therapy published in Chinese databases(China Journal Full-text Data,Wanfang Database,VIP Database)and Eng-lish databases(PubMed,Web of Science,MEDLINE)from January 2011 to November 2021 was searched and bibliometric analy-sis was performed.The visualization analysis was performed using VOS viewer software.Results A total of 595 publications were included in the analysis.The top three countries for English publications were the USA,China,and Japan.The type of stud-ies were predominantly cohort studies,with sample sizes mostly being below 1 000.Risk factors for antithrombotic therapy are cat-egorized into those affecting antiplatelet drugs,warfarin,and new oral anticoagulants.Age,gender,renal function,and combination of antithrombotic drugs are common risk factors,and different risk factors of antithrombotic drugs also have their characteristics.Conclusion While there is substantial research on risk factors in antithrombotic therapy globally,the sample size needs to be improved.Pharmacists should provide individualized medication services based on different drugs and different groups to ensure medication safety for patients.

Objective To examines the correlation between lifestyle factors and semen quality among sperm donors at Anhui human sperm bank.Methods Demographic and lifestyle data were collected from 1,222 volunteers who donated sperm between January 2021 and December 2023,and their association with semen quality was analyzed.Results Univariate chi-square analysis revealed significant associations between several lifestyle factors and abnor-mal semen parameters(P＜0.05),including non-student status,frequent masturbation,short-term abstinence,low exercise frequency,frequent staying up late,smoking,drinking,and short sleep duration.Moreover,multiva-riate logistic regression analysis demonstrated that non-student status,longer abstinence time,and insufficient sleep were linked to abnormal semen volume.Additionally,abstinence time,exercise frequency,staying up late,smok-ing,and sleep duration were significantly correlated with abnormal semen concentration and sperm motility(P＜0.05).Conclusion Analysis reveals a close relationship between semen quality and volunteers'lifestyles,inclu-ding factors such as abstinence time,staying up late,sleep duration,smoking,drinking,and exercise frequency.
