Objective: To explore the impact of adverse childhood experiences (ACEs) on health risk behaviors (HRBs) among college students and the mediating role of psychological symptoms, so as to provide a basis for developing intervention strategies. Methods: From March to April 2023, a convenience cluster sample of 1 801 students from 12 universities in Nanning, Liuzhou, Guilin, Wuzhou of Guangxi completed an online survey. A self designed questionnaire, Adverse Childhood Experiences-International Questionnaire (ACE-IQ) and Symptom Checklist-90 (SCL-90) were used for evaluation tools. Binary Logistic regression, structural equation modeling (SEM) and Bootstrap methods were used to analyze the associations and mediating effects. Results: Overall, 71.2% of college students experienced at least one type of ACE, with emotional neglect (40.3%) and emotional abuse ( 25.2 %) having the highest detection rates. The top three HRBs were unhealthy diet (77.8%), physical inactivity (54.1%), and smoking/alcohol use (18.5%). Logistic regression showed that poor family functioning, abuse, and extra familial violence were each associated with an increased risk of smoking/alcohol use ( OR =1.14, 1.11, 1.18) and deliberate self harm ( OR =1.26, 1.19,1.30) (all P <0.05). Experience of abuse increased the risk of high risk sexual behavior and family dysfunction increaded the risk of physical inactivity, respectively ( OR = 1.07 , 1.04, both P <0.05). Mediation analysis revealed that anxiety ( β =0.20) and depression ( β = 0.09 ) partially mediated the pathway from poor family functioning to deliberate self harm; paranoia ( β =0.02) partially mediated the pathway from abuse to high risk sexual behavior; and obsessive-compulsive symptoms ( β =0.26) and depression ( β =0.10) partially mediated the pathway from extra familial violence to deliberate self harm (all P <0.05). Conclusion Psychological symptoms play a mediating role in the association between ACEs and HRBs, and mental health interventions may reduce the risk of HRBs among college students.

Objective To understand the current situation of healthcare-associated infection(HAI)in China,pro-vide data support and decision-making basis for formulating scientific and effective strategies for HAI prevention and control.Methods A nationwide cross-sectional survey on HAI was conducted among various types and levels of medical institutions in China according to a unified protocol of bedside surveys and case investigations.Results In 2024,a total of 5 736 medical institutions and 2 751 765 patients were surveyed.Among them,34 889 HAI cases were identified,with a prevalence rate of 1.27％.The number of HAI episodes was 38 032,and case prevalence rate was 1.38％.The prevalence rate of HAI in medical institutions in different regions of China ranged from 0.66％to 2.35％.Among medical institutions of different scales,those with a bed capacity of ≥900 had the high-est incidence of HAI,reaching 1.65％.The most common infection site was the lower respiratory tract(44.66％),followed by the urinary tract(12.94％),surgical site(9.32％),upper respiratory tract(7.02％),and bloodstream infection(5.78％).The top 3 departments with the highest HAI rates were the general intensive care unit(10.02％),department of neurosurgery(5.51％),and department(group)of hematology(5.34％).A total of 23 238 strains of HAI pathogens were detected,with 10 714 strains(46.10％)from lower respiratory tract speci-mens.The top 5 detected strains were Klebsiella pneumoniae(14.76％),Pseudomonas aeruginosa(13.33％),Escherichia coli(12.79％),Acinetobacter baumannii(9.23％),and Staphylococcus aureus(7.88％).231 944 pa-tients underwent class Ⅰ incision surgery were monitored,with 1 647 cases experienced surgical site infection,and the prevalence rate of surgical site infection was 0.71％.The number of patients who should undergo pathogen de-tection(patients receiving therapeutic and therapeutic combined prophylactic antimicrobial agents)was 715 179,while the actual number was 480 492,with a pathogen detection rate of 67.18％.425 225 patients received patho-genic detection before treatment,with a detection rate of 59.46％.Conclusion The overall HAI prevalence in Chi-na is lower,showing disparities among medical institutions of different regions and scales.Therefore,precise imple-mentation of measures is necessary for HAI prevention and control,with a focus on high-risk institutions and high-risk departments,key areas,and critical procedures.All levels of medical institutions should continuously reduce the incidence of HAI by strengthening monitoring,standardizing the use of antimicrobial agents,and reinforcing basic HAI prevention and control measures.

Functional gastrointestinal disorders (FGIDs) are debilitating diseases of the digestive system that severely impair an individual's quality of life and impose a significant economic burden. However, the mechanisms underlying the pathogenesis of FGIDs and effective treatment options remain unclear. Transcutaneous auricular vagus nerve stimulation (taVNS), a novel neuromodulation therapy, has shown promising therapeutic outcomes in the treatment of FGIDs. This study conducted a comprehensive analysis of the development of taVNS and its relationship with vagus nerve stimulation and explored the clinical application of taVNS in managing FGIDs, including functional dyspepsia, irritable bowel syndrome, and functional constipation. Additionally, this study investigated the pathophysiological mechanisms of taVNS in FGIDs and reviewed its application as a holistic treatment approach, aiming to provide new insights into its therapeutic potential.

Objective:To explore the effect of applying scaffolding teaching to infectious disease teaching.Methods:The study selected 259 undergraduate nursing students of Batch 2017 as the research objects, and they were randomly divided into an experimental group (126 students) and a control group (133 students) according to the odd and even numbers of their student numbers. The experimental group carried out scaffolding teaching, and the control group adopted traditional teaching. After the teaching, the two groups of students were assessed on the theory of infectious diseases and scenario simulation excercises. The teaching satisfaction of the two groups was assessed through questionnaire surveys. SPSS was used for t test and chi-square test. Results:The experimental group's theoretical assessment and scenario simulation excercises scores were both higher than those of the control group, and the difference was statistically significant ( P<0.05). The results of the questionnaire survey showed that the experimental group students were more satisfied with the scaffolding teaching model [80.2% (101/126)], which was higher than that of the control group [54.1% (72/133)], with statistically significant differences ( P<0.001). Conclusion:Scaffolding teaching is helpful to improve teaching quality and satisfaction in infectious disease teaching, and it is worthy of further promotion and application in educational practice.

With the reform of medical insurance payment mode and the promotion of medical insurance policy, medical insurance management has become the core of public hospital operation and management. According to the business scenario of medical insurance management in public hospitals, medical insurance intelligent management can be divided into three levels: automatic medical insurance intelligent management engine based on rules, digital medical insurance management assistance based on dialogue user interface and hospital medical insurance management brain based on deep learning. In August 2020, under the requirements of hospital intelligent management standards, a tertiary hospital broke through the traditional medical insurance management mode to launch the practice of digital enabled panoramic scene intelligent management of medical insurance, which included medical insurance intelligent business audit, medical insurance intelligent reconciliation, medical insurance intelligent cost control and medical insurance intelligent management cockpit. These measures had realized the intellectualization and standardization of medical insurance management and improved the overall operation efficiency of the hospital.

The Sanger sequencing techniques, also known as the first-generation sequencing techniques and the gold standard of sequencing, have promoted the completion of "working draft" of the human genome, but the disadvantages of low throughput and high cost limit its large-scale application. The second-generation sequencing techniques, also known as the next-generation sequencing techniques, have widely used in basic research and clinical application because of its high throughput and low cost, but the short reads has always been an unavoidable shortcoming. Then, the emergence of the third-generation sequencing techniques, with the long reads, provides new technology selection for the analysis of complex repetitive regions on genome sequences and the assembly of high-quality genomes. In recent years, the third-generation sequencing techniques have been further developed, and have gradually demonstrated the clinical application value. This article reviewed the research progress and clinical application of the third-generation sequencing techniques.

Purpose: This study aimed to investigate the factors associated with chemoresistance to neoadjuvant chemotherapy (NACT) followed by radical hysterectomy (RH) and construct a nomogram to predict the chemoresistance in patients with locally advanced cervical squamous carcinoma (LACSC). Materials and Methods: This retrospective study included 516 patients with International Federation of Gynecology and Obstetrics (2003) stage IB2 and IIA2 cervical cancer treated with NACT and RH between 2007 and 2017. Clinicopathologic data were collected, and patients were assigned to training (n=381) and validation (n=135) sets. Univariate and multivariate analyses were performed to analyze factors associated with chemoresistance to NACT. A nomogram was built using the multivariate logistic regression analysis results. We evaluated the discriminative ability and accuracy of the model using a concordance index and a calibration curve. The predictive probability of chemoresistance to NACT was defined as > 34%. Results: Multivariate analysis confirmed menopausal status, clinical tumor diameter, serum squamous cell carcinoma antigen level, and parametrial invasion on magnetic resonance imaging before treatment as independent prognostic factors associated with chemoresistance to NACT. The concordance indices of the nomogram for training and validation sets were 0.861 (95% confidence interval [CI], 0.822 to 0.900) and 0.807 (95% CI, 0.807 to 0.888), respectively. Calibration plots revealed a good fit between the modelpredicted probabilities and actual probabilities (Hosmer-Lemeshow test, p=0.597). Furthermore, grouping based on the nomogram was associated with progression-free survival. Conclusion We developed a nomogram for predicting chemoresistance in LACSC patients treated with RH. This nomogram can help physicians make clinical decisions regarding primary management and postoperative follow-up of the patients.

Objective: To assess the association of socioeconomic status with the burden of cataract blindness in terms of year lived with disability (YLD) rates and to determine whether ultraviolet radiation (UVR) levels modify the effect of socioeconomic status on this health burden. Methods: National and subnational age-standardized YLD rates associated with cataract-related blindness were derived from the Global Burden of Disease (GBD) study 2017. The human development index (HDI) from the Human Development Report was used as a measure of socioeconomic status. Estimated ground-level UVR exposure was obtained from the Ozone Monitoring Instrument (OMI) dataset of the National Aeronautics and Space Administration (NASA). Results: Across 185 countries, socioeconomic status was inversely associated with the burden of cataract blindness. Countries with a very high HDI had an 84% lower age-standardized YLD rate [95% confidence interval ( Conclusion Long-term high-UVR exposure amplifies the association of poor socioeconomic status with the burden of cataract-related blindness. The findings emphasize the need for strengthening UVR exposure protection interventions in developing countries with high-UVR exposure.
