Objective: To examine the association between health behaviors and depressive symptoms among junior and senior high school students, so as to provide evidence for combined behavioral interventions targeting adolescent mental health. Methods: From September to November 2023, a stratified cluster random sampling method was used to recruit 104 834 junior and senior high school students from all 13 prefecture level cities (124 districts/counties) in Heilongjiang Province, China. Multivariable Logistic regression models, as well as multiplicative and additive interaction analyses were employed to analyze the associations between health behaviors and depressive symptoms, and Chi-square tests for trend were conducted to explore ,the changing tendency in the risk of depressive symptoms with increasing numbers of health behaviors among junior and senior high school students. Results: Healthy diet ( OR =0.66, 95% CI =0.63-0.68), healthy physical activity ( OR =0.47, 95% CI =0.45-0.49), healthy outdoor activity ( OR =0.55, 95% CI =0.52-0.57), healthy sleep ( OR =0.72, 95% CI =0.69-0.75), and healthy screen use ( OR =0.79, 95% CI =0.76-0.82) were independently associated with lower rates of depressive symptoms (all P <0.01). The risk of depressive symptoms decreased progressively with an increasing cumulative number of health behaviors ( χ 2 trend =996.73, P <0.01). Except for the interaction between healthy diet and healthy sleep, significant additive interactions were observed among the remaining health behaviors( RERI =0.07-0.23,all P <0.05). The probability of depressive symptoms was lower among girls with 2-3 healthy behaviors than among boys ( Z =2.51, 2.65), lower among urban students with 2-3 healthy behaviors than among suburban county students ( Z =-2.36, -2.04), and lower among senior high school students with 2-4 healthy behaviors than among junior high school students ( Z =2.17, 2.10, 2.04) (all P <0.05). Conclusions Health behaviors are significantly associated with depressive symptoms among junior and senior high school students. The probability of depressive symptoms is lower among girls, urban students, and senior high school students who engage in multiple healthy behaviors. Implementing combined interventions targeting multiple health behaviors in these populations may yield greater benefits.

AIM To investigate the clinical effects of Mahuang Fuzi Xixin Decoction combined with non-immunosuppressive treatment on patients with focal segmental glomerulosclerosis due to Spleen-Kidney Yang Deficiency.METHODS Sixty patients were randomly assigned into control group(30 cases)for 24-week intervention of non-immunosuppressive treatment,and observation group(30 cases)for 24-week intervention of both Mahuang Fuzi Xixin Decoction and non-immunosuppressive treatment.The changes in clinical effects,TCM syndrome effects,TCM syndrome score,24 h UTP,ALB,eGFR,Nephrin,Podocin and safety indices were detected.RESULTS The observation group demonstrated higher total effective rate and TCM syndrome effective rate than the control group(P＜0.05).After the treatment,the two groups displayed decreased TCM syndrome score,24 h UTP,Nephrin,Podocin(P＜0.05),and increased ALB(P＜0.05),especially for the observation group(P＜0.05).No obvious adverse reactions occured in the two groups.CONCLUSION For the patients with focal segmental glomerulosclerosis due to Spleen-Kidney Yang Deficiency,Mahuang Fuzi Xixin Decoction combined with non-immunosuppressive treatment can improve TCM syndromes,whose action mechanism may be contribute to the alleviation of podocyte injury.

Objective:To evaluate the accuracy and output stability of online general natural language processing(NLP)models for staging diagnosis and identifying medium-and high-risk factors in cervical cancer patients based on pathology reports.Methods:Surgical pathological reports of 65 patients with cervical cancer who received postoperative adjuvant radiotherapy at Shanghai General Hospital from January 2022 to December 2023 were retrospectively selected.These reports were input into two online NLP models,Kimi and ChatGPT-4o,and their output staging diagnosis results were recorded.Then,the results were classified into 3 categories and scored as follows:correct(2 points),basically correct(1 point)and incorrect(0 point).Each pathologic report was tested 5 times to assess the stability of the outputs form Kimi and ChatGPT-4o,and the consistency between the NLP models and clinical physicians in cervical cancer staging was compared.Prompt-based questioning was used to evaluate Kimi's ability to extract medium-and high-risk factors from the pathology reports of cervical cancer patients.Results:There was no statistical significant difference in the staging diagnosis results between the two NLP models and the clinical physicians(x2=5.740,P=0.057).Kimi and ChatGPT-4o respectively produced 56 and 47 correct results,6 and 15 basically correct results,and 3 and 3 incorrect results.Their mean scores were 7.08±2.70 and 7.97±2.97,and the difference between them was statistically significant(P=0.040).In the extraction of risk factors from 65 cervical cancer patients,involving a total of 390 factors,Kimi made only three false-positive errors,with all other factors correctly identified.Conclusion:Online general NLP models can stably output the stage of cervical cancer patients with diagnostic accuracy comparable to clinical physicians.With the assistance of prompt-based questioning,these NLP models can accurately extract medium-and high-risk factors from pathology reports of cervical cancer patients,demonstrating promising clinical application potential.

As a serine protease,thrombin can convert soluble fibrinogen into insoluble fibrin and plays a pivotal role in the coagulation cascade.Therefore,the accurate quantitative assay of thrombin levels is of great value in the evaluation of coagulation function,clinical screening and prognostic monitoring of coagulation-related diseases,and screening of drugs for targeted therapy.Existing methods for thrombin detection can be divided into two categories,e.g.,the assay of concentration levels using nucleic acid aptamers as the affinity elements and the assay of activity levels based on the hydrolytic cleavage of substrate peptides.In recent years,electrochemical biosensors have attracted much attention in thrombin detection due to high sensitivity,high selectivity,simple instrument,fast response,and good portability.In this review,the latest research progress in methods for electrochemical detection of thrombin was summarized,focusing on the detection principles and the applied signal amplification strategies of related electrochemical biosensors.In addition,the challenges with respect to the practical use of electrochemical thrombin biosensors and the prospects were discussed.

OBJECTIVE: Hepatocellular carcinoma (HCC) is sensitive to ferroptosis, a new form of programmed cell death that occurs in most tumor types. However, the mechanism through which ferroptosis modulates HCC remains unclear. This study aimed to investigate the oncogenic role and prognostic value of FANCD2 and provide novel insights into the prognostic assessment and prediction of immunotherapy. METHODS: Using clinicopathological parameters and bioinformatic techniques, we comprehensively examined the expression of FANCD2 macroscopically and microcosmically. We conducted univariate and multivariate Cox regression analyses to identify the prognostic value of FANCD2 in HCC and elucidated the detailed molecular mechanisms underlying the involvement of FANCD2 in oncogenesis by promoting iron-related death. RESULTS: FANCD2 was significantly upregulated in digestive system cancers with abundant immune infiltration. As an independent risk factor for HCC, a high FANCD2 expression level was associated with poor clinical outcomes and response to immune checkpoint blockade. Gene set enrichment analysis revealed that FANCD2 was mainly involved in the cell cycle and CYP450 metabolism. CONCLUSION To the best of our knowledge, this is the first study to comprehensively elucidate the oncogenic role of FANCD2. FANCD2 has a tumor-promoting aspect in the digestive system and acts as an independent risk factor in HCC; hence, it has recognized value for predicting tumor aggressiveness and prognosis and may be a potential biomarker for poor responsiveness to immunotherapy.

Creutzfeldt-Jakob disease(CJD)is a rapidly progressive and fatal neurodegenerative disorder caused by prions,with certain infectivity and iatrogenic transmission risks.With the rapid progress and application of new dia-gnostic biomarkers and detection methods,as well as the construction and improvement of surveillance and reporting systems,the detection of CJD in patients domestically and internationally has shown an increasing trend year by year.Due to its long incubation period and heterogeneity of early symptoms,early identification and diagnosis of the disease is difficult,increasing the risk of transmission within medical institutions.Currently,there is a lack of con-sensus on the infection prevention and control of CJD.In order to timely identify and diagnose CJD as well as effec-tively block its transmission in medical institutions,this consensus summarizes 15 clinical concerns and formulates 24 specific recommendations based on the latest domestic and international research findings and clinical evidence,as well as combines with clinical practice,aiming to standardize healthcare-associated infection prevention and control measures for CJD and reduce its transmission risk in medical institutions.

Objective:To investigate the correlation between the density and volume of left atrial-epicardial adipose tissue(LA-EAT)and the occurrence and severity of atrial fibrillation(AF)in elderly patients.Methods:This was a retrospective case-control study.A total of 197 elderly patients with AF and 82 patients with sinus rhythm who were hospitalized in the Department of Cardiology and Geriatric Cardiology of the First Affiliated Hospital of Nanjing Medical University from June 2023 to July 2024.were selected.The AF group was further divided into paroxysmal AF(PAF)subgroup(111 cases)and persistent AF(PeAF)subgroup(86 cases). The density and volume of LA-EAT in all patients were meansured by coronary artery enhanced CT or left atrial enhanced CT.The differences in LA-EAT density, volume and related data among the 3 groups were compared, and their relationship with different severity of senile AF was analyzed.Logistic regression was used to analyze whether LA-EAT density and volume were risk factors for senile AF.The predictive value of LA-EAT density and volume for AF in the elderly was compared throuh restricted cubic spline analysis.Results:The average LA-EAT density in the sinus rhythm group, PAF group and PeAF group was -82.75(-87.15, -79.63), -81.70(-85.55, -75.85)and -80.45(-83.40, -76.10)HU, respectively; the standard deviation of density was 34.70(31.93, 36.28), 36.20(34.30, 37.65)and 35.45(33.63, 37.28)HU, respectively; the LA-EAT volume was 23 483.40(13 964.10, 31 645.53), 25 112.20(18 479.10, 36 917.50)and 37 836.50(25 933.80, 45 537.90)mm 3, respectively.The LA-EAT density and volume in the PAF group and PeAF group were higher than those in the sinus rhythm group(all P<0.05). The LA-EAT volume in the PeAF group was greater than that in the PAF group( P<0.001), but there was no significant difference in LA-EAT density between the two groups( P>0.05). Multivariate logistic regression analysis showed that LA-EAT density and volume, left atrial diameter(LAD)and body mass index(BMI)were the independent risk factors for AF in the elderly( P<0.05). Conclusions:LA-EAT density and volume are significantly correlated with occurrence of senile AF, and show a positive dose-response relationship.LA-EAT volume is significantly related to the severity of AF( P<0.05), while the density is not significantly related to it( P>0.05).

Objective To explore the different potential subtypes of psychosocial adaptation among young and middle-aged stroke patients,and analyze the relationship between different potential subtypes and quality of life,so as to provide references for the subsequent development of targeted interventions.Methods A total of 406 young and middle-aged stroke patients in 4 tertiary hospitals in Suzhou from June 2023 to June 2024 were recruited by convenience sampling.The General Information Questionnaire,the Self-Report Psychosocial Adjustment to Illness Scale and the EuroQol five-dimensional questionnaire were conducted for investigation.Latent profile analysis was used to explore the potential subtypes of psychosocial adaptation among young and middle-aged stroke patients.Generalized linear regression analysis was conducted with quality of life as dependent variables.Results A total of 380 young and middle-aged stroke patients were included.The psychosocial adaptation of patients could be classified into 3 potential subtypes:high adaptation level type(23.90％),medium adaptation level with health concerns type(46.40％),and low adaptation level with psychological barriers type(29.70％).The results of generalized linear regression analysis showed that potential subtypes of psychosocial adaptation were the influencing factors for quality of life in young and middle-aged stroke patients(P＜0.05).Conclusion There was group heterogeneity in psychosocial adaptation among young and middle-aged stroke patients,and the potential subtype of psychosocial adaption was an important factor affecting the quality of life of patients.It is suggested that medical staff should focus on patients with low adaptation level with psychological barriers type,and take targeted interventions according to characteristics of different subtypes of patients,so as to improve their quality of life.

Objective:To investigate the prevalence and risk factors of the 4 most common functional gastrointestinal disorders (FGID) among school-aged children in Shanghai.Methods:A cross-sectional questionnaire survey was conducted from January to December 2019. Using stratified cluster sampling, 26 097 students in grades 1-12 from Huangpu and Jiading District, Shanghai were enrolled. The questionnaire of pediatric gastrointestinal symptoms-Rome Ⅳ (QPGS-Ⅳ) and the pediatric quality of life inventory (PedsQL) were used to assess the prevalence and health-related quality of life (HRQoL) of functional dyspepsia (FD), irritable bowel syndrome (IBS), functional abdominal pain-not otherwise specified (FAP-NOS), and functional constipation (FC). Multivariate Logistic regression analysis was performed to identify correlations between sociodemographic factors, lifestyle habits, comorbidities and 4 major FGID. A trend chi-square test was used to explore the relationship between HRQoL scores and FGID prevalence.Results:A total of 26 097 valid participants (26 097/27 036, 96.5%) were included in the study, with the age of (10.8±3.1) years and 12 441 cases (47.7%) were female. The prevalence of FC was found to be the highest (5 537 cases, 21.2%), followed by IBS (797 cases, 3.1%), FAP-NOS (267 cases, 1.0%) and FD (218 cases, 0.8%). Multivariate Logistic regression analysis revealed the following findings: junior high school (FD: OR=1.88 (95% CI 1.35-2.61); IBS: OR=1.42 (95% CI 1.18-1.71); FAP-NOS: OR=1.39 (95% CI 1.02-1.90)), senior high school (FD: OR=2.67 (95% CI 1.84-3.86);IBS: OR=2.36 (95% CI 1.93-2.89) ;FAP-NOS: OR=2.20 (95% CI 1.56-3.11)) and frequent respiratory infections (FD: OR=2.15 (95% CI 1.45-3.18); IBS: OR=2.59 (95% CI 2.12-3.16); FAP-NOS: OR=1.49 (95% CI 1.00-2.21)) were common risk factors for FD, IBS and FAP-NOS. Allergic symptoms (FD: OR=2.21 (95% CI 1.56-3.14); IBS: OR=2.30 (95% CI 1.04-1.51); FAP-NOS: OR=2.54 (95% CI 1.85-3.50); FC: OR=1.09 (95% CI 1.01-1.17)) was a common risk factor for FD, IBS, FAP-NOS and FC. Family history of allergy was a risk factor for IBS ( OR=1.41 (95% CI 1.20-1.65)) and FAP-NOS ( OR=1.33 (95% CI 1.01-1.74)). Female exhibited increased risks for FD ( OR=1.49 (95% CI 1.13-1.96)), IBS ( OR=1.50 (95% CI 1.30-1.74)) and FC ( OR=1.10 (95% CI 1.03-1.17)). The presence of dietary bias was associated with of IBS ( OR=1.46 (95% CI 1.26-1.69)) and FC ( OR=1.26 (95% CI 1.19-1.34)); late bedtime ( OR=1.32 (95% CI 1.06-1.64)) and allergen exposure ( OR=1.25 (95% CI 1.04-1.51)) were risk factors for IBS. Insufficient sleep ( OR=1.11 (95% CI 1.02-1.21)), insufficient outdoor time ( OR=1.20 (95% CI 1.01-1.43)) and severe lack of outdoor time ( OR=1.48 (95% CI 1.23-1.76)) were significant risk factors for FC. Pet ownership ( OR=1.39 (95% CI 1.07-1.81)) was a risk factor for FAP-NOS. HRQoL scores were significantly lower in children with FD, IBS, or FAP-NOS compared to non-FGID peers (all P<0.05). χ2 trend test analysis showed that the Pearson correlation coefficients between the prevalence of FD, IBS, FAP-NOS, FC and HRQoL scores were -0.93, -0.93, -0.97 and -0.84, respectively. Conclusions:The prevalence of FGID among school-aged children in Shanghai varies by sub-type. FC was the most prevalence. Junior and senior high school, female sex, allergic symptoms and frequent respiratory infections were major risk factors. Meanwhile, dietary bias, late bedtime, insufficient outdoor time and pet ownership were associated with specific subtypes. The HRQoL is significantly reduced in children with FD, IBS and FAP-NOS.
