Objective: To analyze the developmental trajectories of clustered health risk behaviors and their association with self-esteem and lonelinesss among junior high school students, so as to provide a reference for formulating comprehensive prevention and control measures of health risk behaviors among adolescents. Methods: In October 2023, 1 165 first year junior high school students from two schools of Jishou City in Hunan Province were selected by convenient sampling method for three follow up surveys (T1:October 2023; T2:April 2024; T3:October 2024). The Adolescent Health Risk Behavior Questionnaire, Rosenberg Self esteem Scale and Loneliness Scale were used to assess health risk behaviors, self esteem and loneliness, respectively. Latent growth curve modeling and latent growth mixture modeling were applied to analyze the developmental trajectories of clustered health risk behaviors among junior high school students. Logistic regression was used to analyze the association of the developmental trajectories of clustered health risk behaviors with self esteem and loneliness among junior high school students. Results: The overall developmental trajectories among junior high school students showed a declining trend (intercept=0.15, slope=-1.65, both P <0.05), with three heterogeneous categories:low risk improvement group ( n =862, 74.0%), moderate risk stable group ( n =260, 22.3%), and high risk deterioration group ( n =43, 3.7%). After adjusting the status of the left behind individuals，using the low risk improvement group as the reference category in multinomial Logistic regression analysis, results indicated that higher loneliness scores among junior high school students increased the risks of belonging to the moderate risk stable group ( OR=1.02, 95%CI =1.00- 1.04 ) and the high risk deterioration group ( OR=1.04, 95%CI =1.00-1.08), while higher self esteem scores reduced the risks of belonging to the moderate risk stable group ( OR=0.93, 95%CI =0.91-0.96) and the high risk deterioration group ( OR=0.88, 95%CI =0.83-0.94) (all P <0.05). Conclusions The overall trend of clustered health risk behaviors among junior high school students gradually improves, and the self esteem and loneliness are significant correlative factors. Targeted intervention measures should be developed for the junior high school students, with a focus on enhancing their self esteem and alleviating loneliness.

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.

Purpose: In this study, the neural communication patterns between hypothalamic structures and cortical areas in girls diagnosed with central precocious puberty (CPP) were explored. Endocrine profiles were incorporated to clarify the pathophysiological interactions between cerebral networks and hormonal regulation. The hypothalamus was designated as the key focus area for connectivity analysis. Methods: Fifty-seven girls (37 CPP, 20 non-CPP) were recruited from the Pediatric Development Clinic at the Second Affiliated Hospital of Anhui Medical University. The collected data included demographic information, gonadotropin-releasing hormone stimulation tests, and magnetic resonance imaging scans. Hypothalamic functional connectivity (FC) was analyzed using predefined region of interest coordinates, and correlations between hormone levels and FC values were assessed. Results: Compared to the non-CPP group, the CPP group exhibited elevated baseline follicle-stimulating hormone (FSH), baseline luteinizing hormone (LH), peak FSH, peak LH, and peak LH/FSH ratios. Patients with CPP exhibited enhanced neural synchronization linking the right lateral hypothalamic effector zone to the right superior frontal gyrus (displaying a borderline significant correlation with peak LH concentrations), concurrent with diminished functional coupling of the right lateral hypothalamic efferent to the right fusiform/supramarginal gyri. The left lateral hypothalamic projections demonstrated amplified connectivity with the right cuneus. No FC differences were observed in the medial hypothalamus. Conclusion Abnormal lateral hypothalamus FC patterns were identified in CPP girls and were particularly linked to peak LH levels. The findings offer novel insights into the neuroendocrine mechanisms underlying CPP.

Objective To analyze the incidence rate and risk factors of atrial fibrillation (AF) in elderly patients with chronic obstructive pulmonary disease (COPD). Methods A total of 392 patients with COPD in the hospital were selected from December 2020 to December 2024. Patients' data (medical history, echocardiographic data, etc.) were recorded. The incidence rate of AF in patients was recorded and the patients were grouped according to whether or not they developed AF. The differences were compared between the two groups, and the risk factors of AF occurrence in elderly patients with COPD were analyzed. Results Among the 392 patients with COPD, 127 cases (32.40%) met the diagnostic criteria of AF. There were statistically significant differences in age, pulmonary infection, heart failure, diabetes, smoking history, disease duration, LAD, severe renal insufficiency and coronary heart disease between the AF group and the non-AF group (P<0.05). Multivariate logistic regression analysis suggested that age, pulmonary infection, heart failure, diabetes mellitus, smoking history, disease course, LAD, severe renal insufficiency and coronary heart disease were all risk factors for elderly patients with COPD (OR=1.129, 4.246, 3.955, 4.125, 2.038, 1.112, 1.102, 4.397, and 3.865, P<0.05). Conclusion The incidence rate of AF is high in elderly patients with COPD. Age, pulmonary infection, heart failure, diabetes mellitus, smoking history, course of disease, LAD, severe renal insufficiency, and coronary heart disease are all risk factors for AF.

Objective This is to develop a comprehensive performance evaluation index system for physicians under the DRG system and to conduct practical research.Methods The"cost ratio"is used to establish a"sharing coefficient"to define the distribution of performance among physicians treating the same patient;the Delphi technique is applied to ascertain the weights of evalation index,and the weighted comprehensive index method is utilized to construct the performance evaluation index system for DRG physicians;empirical research on physician performance evaluation is conducted using hospital data.Results Following performance sharing and weighted integration,the basic evaluation indicators and the performance evaluation index of DRG both exhibit an approximate normal distribution between 0～100 points;the performance evalation index of DRG score can be utilized for the overall assessment of physicians,and the strengths and weaknesses of physician diagnosis and treatment can be analyzed based on various dimensional indices and scores.The performance sharing of the evaluation results of the same physician is more accurate than the traditional method,especially for the physicians with more transferred patients.Conclusion Using the"allocation coefficient"to divide the weight of"one patient and multiple doctors"and incorporating the weight into the comprehensive evaluation index system make the results more objective and accurate.The comprehensive performance evaluation index system for DRG physicians,based on the"sharing coefficient"and weighted comprehensive index method,offers a scientific and practical tool for hospital performance distribution management.

Objective:To investigate the effects of the novel oral edaravone(EDA)on rats with diabetic encepha-lopathy(DE).Methods:The network pharmacology research methodology was employed to elucidate the mechanism of action of oral EDA in the treatment of diabetes mellitus,identify intersecting targets,and conduct initial validation of these findings in vivo.Thirty male SD rats were randomly assigned to three groups:A normal control(control)group,a diabetic encephalopathy DE(DE)group,and an oral edaravone treatment(DE+EDA)group.Diabetic encephalop-athy was induced in both the DE and DE+EDA groups using the streptozotocin(STZ)method.After successful model-ing,the DE+EDA group received oral administration of EDA,while the other two groups were administered equal doses of saline as controls.Serum samples were examined for lipid release rate,and the protein expression levels of oxidative stress factor 3-nitrotyrosine(3-NT)and apoptotic factor cysteinyl aspartate specific proteinase-3(caspase-3)in brain tissues were detected by Western blot.Brain samples were stained with HE staining to observe the pathological changes.Histopathological changes were observed through hematoxylin-eosin(HE)staining.Results:Network pharmacological analysis yielded 27 core targets,and functional annotation of gene bioprocesses showed that the intersecting targets were mainly enriched in response to oxidative stress and neuronal apoptosis.Serum-related lipid assay showed that the DE+EDA group had significantly improved lipid metabolism disorders compared with the DE group.Additionally,expression levels of 3-NT and caspase-3 were significantly higher in the DE group when compared with controls(P＜0.05);How-ever,both markers exhibited a significant decrease within the DE+EDA treatment cohort as opposed to their counter-parts in the DE group(P＜0.05).HE staining showed that in DE group the cellular arrangement was disordered,the cells were shrunk with intact plasma membrane,and the nuclei were condensed showing karyopyknosis,fragmented and dissolved.Compared with the DE group,the brain tissue in the DE+EDA group was relatively dense and neatly ar-ranged,and the cell karyopyknosis,fragmentation and lysis were significantly improved.Conclusion:Both network pharmacology and in vivo experiments provide preliminary evidence that oral EDA reduces damage in diabetic encepha-lopathy rats.

Objective To explore the association and diagnostic performance of liver imaging reporting and data system(LI-RADS)CT signs with hepatocellular carcinoma(HCC)both in the LI-RADS target population and patients without LI-RADS-defined HCC risk factors.Methods A retrospective analysis was conducted on the data of 435 patients with 482 hepatic lesions confirmed by pathology.Of these,306 cases were assigned to the HCC group(327 HCC lesions),and other 129 cases were assigned to the non-HCC group(77 malignancies and 78 benign lesions).Receiver operating characteristic(ROC)curve analysis assessed the diagnostic performance of LI-RADS v2018 CT signs for HCC,and logistic regression analyses determined the association of CT signs with HCC.Results The asso-ciation of CT signs with all HCC lesions was statistically significant for non-peripheral washout[odds ratio(OR)15.1;95％ confi-dence interval(CI)5.6-40.4;P＜0.01]and non-rim arterial phase hyperenhancement(APHE)(OR 12.4;95％ CI 7.5-20.5;P＜0.01)higher than enhanced capsule(OR 9.9;95％ CI 2.8-34.8;P＜0.01;OR 2.4;95％ CI 1.4-3.8;P=0.01).The sensitivity,specificity,positive predictive value(PPV),and area under the curve(AUC)for diagnosing HCC were 85％,83％,91％,and 0.84,respectively for non-peripheral washout;82％,77％,88％ and 0.79,respectively for non-rim APHE;and 31％,98％,97％ and 0.65,respectively for enhanced capsule.Sensitivity(88％ vs 87％),specificity(83％ vs 82％),PPV(92％ vs 91％)and AUC(0.90 vs 0.87)were all slightly higher when non-peripheral washout,non-rim APHE,enhanced capsule,and ancillary features were combined for the diagnosis of HCC compared to combining the three major features.Enhanced capsule(OR 13.3;95％ CI 3.6-48.9;P＜0.01),blood products in mass(OR 20.3;95％ CI 2.4-171.4;P＜0.01),and mosaic appearance(OR 37.7;95％ CI 4.2-340.0;P＜0.01)were associations with HCC presenting with atypical imaging features and provided high specificity from 98％ to 99％.Conclusion In theLI-RADS target population and patients without LI-RADS-defined HCC risk factors,LI-RADS v2018 CT signs show excellent diag-nostic performance for HCC.Two ancillary features,blood products in mass and mosaic appearance,show good specificity for HCC with atypical imaging features.

Severe congenital neutropenia(SCN)is a rare disease characterized by the absolute neutrophil count(ANC)less than 0.5× 109/L in peripheral circulating blood.Due to the low neutrophil count,there is an increased risk of bacterial infection.And the most common oral manifestations are severe periodontitis and recurrent oral ulcer.This paper reports a 5-year-old girl with SCN and severe pe-riodontitis.On the basis of systemic treatment,the periodontal inflammation was controlled to a certain extent through periodontal non-sur-gical treatment and regular plaque control by using the WeChat platform for follow-up and oral hygiene.
