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 investigate the etiology and treatment of dysuria shortly after holmium laser enucleation of the prostate (HoLEP) for benign prostatic hyperplasia (BPH), so as to improve the therapeutic efficacy. Methods A retrospective analysis was conducted on 1361 BPH patients who received HoLEP at our hospital during Mar. 2018 and Mar. 2025. All patients underwent ultrasound, computed tomography (CT), urethral probing or radiography, cystourethroscopy, and urodynamic testing. The causes, treatments and prognosis of dysuria after operation were summarized. Results ninety-eight patients (7.2%) experienced dysuria within 3 months after surgery, and all patients received initial urethral dilation. Among the 62 cases with urethral stricture, 28 were treated with urethral dilation (average of 8 sessions), 16 underwent external urethral incision, 8 underwent anterior urethroplasty, and 10 underwent transurethral plasma incision for urethral stricture. Of the 12 cases with residual prostate tissue, 5 underwent urethral plasma prostatectomy and 7 received medication. All of the 12 cases with bladder neck contracture underwent transurethral plasma incision of the bladder neck and local drug injection. Five cases with intravesical blood clots underwent urethral blood clot irrigation, 2 of which developed active bleeding and then underwent electrocoagulation. Four cases with detrusor dysfunction had catheters re-indwelled for one week followed by medication. Two cases with stone and one case with tissue fragment impacted in the urethra underwent urethral holmium lithotripsy and cystoscopic removal. All patients underwent reoperation successfully and experienced complete resolution or significant improvement of urinary difficulties. Conclusion A certain proportion of patients experience dysuria after HoLEP, with diverse etiologies. The combination of prevention and treatment can reduce the incidence of dysuria.

Objective To analyze the factors affecting the prevalence of hyperuricemia(HUA)in an island troop.Methods A total of 1 113 soldiers stationed on an island from December 2021 to December 2022 were selected as research objects by cluster sampling.Their lifestyle and health information were collected.Physical examination and laboratory detection were conducted.Multivariate logistic regression was used to analyze the influencing factors of HUA.Results The prevalence rate of HUA was 21.02%(234/1 113).There were significant differences in the body mass index(BMI),waist-to-hip ratio,triglyceride,alanine aminotransferase,and creatinine between the soldiers with hyperuricemia and the soldiers with normal blood uric acid(P<0.05).Multivariate logistic regression analysis showed that BMI≥24(OR=1.49,95%CI:1.09-2.05),abnormal liver function(OR=2.26,95%CI:1.31-3.92),and dyslipidemia(OR=1.46,95%CI:1.01-2.12)were positively correlated with hyperuricemia;age>30 years old(OR=0.59,95%CI:0.37-0.93)and exercise time>1 h per week(OR=0.46,95%CI:0.22-0.97)were negatively correlated with HUA.Conclusion The prevalence rate of hyperuricemia is at a high level in an island troop.BMI≥24,age≤30 years old,exercise time≤1 h per week,abnormal liver function,and dyslipidemia are the risk factors for HUA.Prevention and control measures should be taken as early as possible for the soldiers with these risk factors.

Objective:To validate the effectiveness of the leaf position data of multi-leaf collimator (MLC) recorded in the Infinity medical linear accelerator log file (LF).Methods:In this study, the establishment of the film dose calibration curve involved two steps. Initially, the pixel values obtained from scanning the film were converted into net optical density values. Subsequently, a sixth-order polynomial fit was performed on the net optical density and dose data. The picket fence (PF) tests were performed on the electronic portal imaging device (EPID) and film, and the corresponding acquired PF test images were analyzed using the relative leaf travel distance, relative leaf position, relative leaf pair full-width half -maximum (FWHM), and relative leaf pair neighbor region width analysis index, and compared with the relevant results in LF. In addition, to investigate the effect of gravity on the recorded leaf position data by the Infinity medical linear accelerator LF, the above PF tests were executed at 0°, 90°, 180°, and 270° gantry angles, respectively. Intergroup differences were assessed with the Wilcoxon rank-sum test.Results:The film dose calibration curve demonstrated high goodness-of-fit, with a correlation coefficient ( R2) of 0.9994. Across all gantry angles, the dispersion of overall leaf position data for EBT3 film, EPID, and LF followed a consistent pattern based on four analysis metrics: EBT3 film > EPID > LF. Moreover, for each analysis metric, inter-tool differences in standard deviations of results were consistently below 0.1 mm, and this pattern was invariant to gantry angle. Conclusions:The leaf position data recorded in the Infinity medical linear accelerator LF have a high degree of accuracy, and can be used as reference for the actual position of the MLC leaf. Furthermore, gravitational forces exhibit negligible impact on leaf position data acquired via LF.

The inference of tissue origin of body fluid stains is crucial for case investigation and court proceedings.However,traditional methods for identification of body fluid stains,such as morpho-logical,chemical,and immunoassay identifications have certain limitations,and there is an urgent need for more efficient methods for confirmatory experiments.In recent years,the rapid development of tran-scriptomics technology has provided new means for the identification of tissue origin of body fluid stains.Different types of RNA in the transcriptome have their own advantages.This paper elaborates in detail on the application of different types of RNA,such as mRNA,miRNA,circRNA,lncRNA,piRNA and microbial transcriptomics in body fluid identification,and summarizes their respective ad-vantages and limitations,in order to provide a reference for related research.

OBJECTIVE: The relationship between fish consumption and stroke is inconsistent, and it is uncertain whether this association varies across predicted stroke risks. METHODS: A cohort study comprising 95,800 participants from the Prediction for Atherosclerotic Cardiovascular Disease Risk in China project was conducted. A standardized questionnaire was used to collect data on fish consumption. Participants were stratified into low- and moderate-to-high-risk categories based on their 10-year stroke risk prediction scores. Hazard ratios ( HRs) and 95% confidence intervals ( CIs) were estimated using Cox proportional hazard models and additive interaction by relative excess risk due to interaction (RERI), attributable proportion (AP), and synergy index (SI). RESULTS: During 703,869 person-years of follow-up, 2,773 incident stroke events were identified. Higher fish consumption was associated with a lower risk of stroke, particularly among moderate-to-high-risk individuals ( HR = 0.53, 95% CI: 0.47-0.60) than among low-risk individuals ( HR = 0.64, 95% CI: 0.49-0.85). A significant additive interaction between fish consumption and predicted stroke risk was observed (RERI = 4.08, 95% CI: 2.80-5.36; SI = 1.64, 95% CI: 1.42-1.89; AP = 0.36, 95% CI: 0.28-0.43). CONCLUSION Higher fish consumption was associated with a lower risk of stroke, and this beneficial association was more pronounced in individuals with moderate-to-high stroke risk.

OBJECTIVE: This study aimed to reexplore minimum iodine excretion and to build a dietary iodine recommendation for Chinese adults using the obligatory iodine loss hypothesis. METHODS: Data from 171 Chinese adults (19-21 years old) were collected and analyzed based on three balance studies in Shenzhen, Yinchuan, and Changzhi. The single exponential equation was accordingly used to simulate the trajectory of 24 h urinary iodine excretion as the low iodine experimental diets offered (iodine intake: 11-26 μg/day) and to further deduce the dietary reference intakes (DRIs) for iodine, including estimated average requirement (EAR) and recommended nutrient intake (RNI). RESULTS: The minimum iodine excretion was estimated as 57, 58, and 51 μg/day in three balance studies, respectively. Moreover, it was further suggested as 57, 58, and 51 μg/day for iodine EAR, and 80, 81, and 71 μg/day for iodine RNI or expressed as 1.42, 1.41, and 1.20 μg/(day·kg) of body weight. CONCLUSION The iodine DRIs for Chinese adults were established based on the obligatory iodine loss hypothesis, which provides scientific support for the amendment of nutrient requirements.

Objective:To evaluate the diagnostic efficacy of B-type natriuretic peptide(BNP)combined with the Evaluation of Guidelines in Syncope Study(EGSYS)score for cardiogenic syncope(CS), and to provide evidence for rapid clinical identification of high-risk patients.Methods:We retrospectively analyzed 366 patients with syncope hospitalized in the department of cardiovascular medicine of Beijing Hospital from January 1, 2016, to December 31, 2022.Based on the international guideline diagnostic criteria, the patients were categorized into four groups: neutrally mediated reflex syncope(NMS)group, orthostatic hypotension(OH)group, cardiogenic syncope(CS)group, and syncope of unknown origin(US)group.BNP levels were measured at admission and EGSYS scores were calculated.Receiver operating characteristic(ROC)curve analysis was performed to assess the diagnostic efficacy of individual and combined indices for CS.Results:A total of 366 syncope patients were included, among which 70 patients(19.1%)were diagnosed with NMS, 25 patients(6.8%)with OH, 44 patients(12.0%)with CS, and 227 patients(62.0%)with US.Patients in the CS group had significantly higher BNP levels and EGSYS scores compared to those in the NMS, OH, and US groups(all P<0.001). The AUC of EGSYS score for diagnosing CS was 0.783(95% CI: 0.711-0.855), while the AUC of BNP level for diagnosing CS was 0.805(95% CI: 0.727-0.884). When BNP level was combined with EGSYS score, diagnostic performance was significantly improved, with the AUC increasing to 0.855(95% CI: 0.792-0.918). Conclusions:The combination of BNP and EGSYS score significantly can improve the diagnostic accuracy of cardiogenic syncope, providing a practical diagnostic strategy for the early identification of high-risk syncope patients in clinical practice.

Objective To investigate the relationship between abnormal expression of angiotensin-converting enzyme(ACE)and lipoprotein(a)[Lp(a)]with hypertension-diabetes comorbidity.Methods A case-control analysis was conducted on 342 patients with metabolic diseases admitted in our hospital between January 2021 and May 2024,and they were divided into in a diabetes-hypertension comorbidity group(114 cases),a diabetes group(114 cases)and a hypertension group(114 cases).Another 114 matched healthy individuals who taking physical examination in our hospital during the same period were subjected and served as the control group.Clinical data were collected and serum levels of ACE and Lp(a)were measured in all the groups.Multivariate logistic regression analysis was applied to analyze the independent risk factors for hypertension-diabetes comorbidity,and ROC curve analysis was performed to evaluate and predict the efficacy.Results The serum levels of ACE and Lp(a)were significantly higher in the comorbidity group than the control,hypertension and diabetes groups(P＜0.01),and in the hypertension and diabe-tes groups than the control group(P＜0.01).After adjusting for waist-to-hip ratio,alanine amin-otransferase and triglyceride,multivariate logistic regression analysis revealed that serum ACE and Lp(a)still were risk factors for the occurrence of hypertension-diabetes comorbidity(P＜0.01).ROC curve analysis demonstrated that when the cut-off value was 39.01 pg/L,ACE had an AUC value of 0.884(95％CI:0.789-0.980),a sensitivity of 76.67％and a specificity of 75.28％in predicting the comorbidity,and when the cut-off value for Lp(a)was 254.33 mg/L,the AUC value was 0.899(95％CI:0.799-0.919),the sensitivity was 85.83％,and the specificity was 82.22％.Their combination improved the AUC value to 0.993(95％CI:0.979-1.000),with a sensitivity of 95.00％and a specificity of 95.28％in the prediction.Conclusion Serum ACE and Lp(a)are independent risk factors for hypertension-diabetes comorbidity,and can be combined together and regarded as biomarkers for early identification of the comorbidity.

Objective:To analyze the epidemiological characteristics of cases involving monkey injuries at medical institutions surrounding Qianlingshan Park in Guiyang City, and to provide a reference basis for preventive measures to reduce monkey injuries and standardized post-exposure treatment.Methods:A retrospective cross-sectional study was conducted, collecting 1 900 cases of monkey-induced injuries in Qianlingshan Park treated at the outpatient clinic of Guizhou Provincial Center for Disease Control and Prevention and the Department of Surgery at Qianling Hospital, Guiyang City, from 2021 to 2024. Statistical analysis was performed using Pearson′s chi-square test.Results:Total of 1 900 cases of monkey-related injuries in Qianlingshan Park were collected from 2021 to 2024. The exposure time distribution exhibited significant seasonality, with 48.58% of cases occurring during July and August, totaling 923 cases, indicating a peak in the summer. There were 774 male patients and 1 126 female patients, with a ratio of 1∶1.45.and significant differences were observed between different age groups and genders (χ2=195.00, P<0.001), with the highest number of cases occurring in the 0-9 and 20-29 age groups, accounting for 22.05%(419 cases) and 21.79%(414 cases), respectively. The upper limbs were the most common injury site, accounting for 50.84% of the total cases(966 cases in total), with significant differences between gender and injury location (χ2=22.00, P<0.001), Among females, the proportion of injuries to the upper and lower limbs (30.11% and 16.47%, respectively) was higher than that among males (20.74% and 8.63%, respectively). The majority of injuries were classified as Grade Ⅲ, making up 57.38% of cases(1 069 cases in total). Self-treatment after exposure was the most common approach(60.44%), with significant differences observed between wound severity and treatment method (χ2=6.90, P=0.032), Patients with Grade Ⅱ and Grade Ⅲ wounds were more likely to choose self-management (26.84% and 33.23%, respectively) than outpatient management (15.14% and 24.15%). Approximately 98.05% (1 863 cases) of monkey-injured patients had received rabies vaccinations. Conclusions:This study analyzes monkey-related injuries in Qianlingshan Park from 2021 to 2024, clarifying the temporal distribution of injuries, demographic characteristics, injury sites, and treatment methods.
