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.

Immune checkpoint inhibitors are effective tumor treatment agents with survival benefits.However,immune toxicity to various organs has become a new challenge in clinical practice.The cardiac involvement can be presented as heart failure,arrhythmia(atrial fibrillation,atrioventricular block,bundle branch block,ventricular tachycardia,etc.),myocardial-pericarditis,myocardiopathy,and sudden cardiac death,etc.This patient developed abnormally increased myocardial enzymes,impaired cardiac function,and atrioventricular block after 1-month treatment with tislelizumab.Endomyocardial biopsy examination confirmed the diagnosis of immune checkpoint inhibitor-associated myocarditis.Through the diagnosis,treatment,and review of relevant literatures of this case,we wish to improve the understanding of immune checkpoint inhibitor-associated myocarditis,and therefore improve the diagnosis and treatment of immune checkpoint inhibitor-associated myocarditis for clinicians.

Objective To discusse the application effects of the informatization of the review center and the homogeneity of pharmacists on the rationality of emergency department prescriptions.Methods Based on the system rules of the rational drug use management system and manually set custom rules,the changes in pharmacist's review quality,efficiency homogeneity,and prescription rationality were compared before(February 2023 to July 2023)and after(August 2023 to January 2024)the construction of the review center,according to the informatization and process standardization management.Results After the establishment of the review center,analysis of variance showed that the approval rate of pharmacist's review significantly increased compared to before the establishment of the review center(P＜0.05),while the average time consumption increased significantly(P＜0.01).The average review time,average approval time,and average review return time have been extended from(4.50±0.58),(4.50±0.58),and(4.75±0.96)s to(11.67±1.03),(8.50±0.55)and(13.17±0.98)s,respectively.The trend chi-square test showed that the irrationality rate of emergency department prescriptions decreased monthly from 6.27％in August 2023 to 0.93％in January 2024(P＜0.01).Correlation analysis between the number of intervention system rules since the establishment of the review center and the irrationality rate of emergency department prescriptions revealed a significant correlation(P=0.004 4).Conclusions By utilizing the platform of the review center,establishing dedicated review pharmacists and an information pharmacist team,and implementing informatization and standardized management processes,it can contribute to improving the quality and efficiency of prescription review,increasing the qualification rate of prescriptions,ensuring rational drug use,and enhancing the management level and medical quality of hospitals.

Objective To explore the characteritics of spontaneous brain functional activities for patients with hand dysfunction after ischemic stroke using resting state functional magnetic resonance imaging(rs-fMRI).Methods From August,2024 to June,2025,23 patients with hand dysfunction after ischemic stroke were as patients group,and ten age-matched healthy adults were recruited as healthy control group.The patients group was as-sessed with Fugl-Meyer Assessment-Upper Extremities(FMA-UE),Wolf Motor Function Test(WMFT)and modified Lindmark Scale.All subjects underwent rs-fMRI examinations,and the amplitude of low frequency fluctuations(ALFF),fractional amplitude of low frequency fluctuations(fALFF)and regional homogeneity(Re-Ho)were compared between two groups.The resting state functional network was constructed based on indepen-dent component analysis,and the functional connectivity(FC)were analyzed.The rs-fMRI indicators of the pa-tients and the clinical scale scores were analyzed.Results Compared with the healthy control group,the zALFF value decreased in the precentral gyrus(P<0.05,FWE corrected)in the patient group,as well as the values of zfALFF in Cerebelum-Crus2-R(P<0.05,FWE correct-ed),and ReHo values in the putamen(P<0.05,corrected by Alpha Sim).FC of the inferior frontal gyrus(IF-Goperc.R)in the executive control network enhanced(P<0.05,Alpha Sim corrected),while FC of the middle oc-cipital gyrus(MOG.L)in the dorsal attention network(DAN)weakened(P<0.05,Alpha Sim corrected).There was a positive correlation between FC of MOG.L in the patient's DAN and the scores of FMA-UE(r=0.439,P=0.036),WMFT(r=0.516,P=0.012),and modified Lindmark Scales(r=0.425,P=0.043).Conclusion The resting state spontaneous activity of some brain areas of the cerebrum,cerebellum and basal ganglia is reduced in patients with hand dysfunction after ischemic stroke,and some brain network connections are abnor-mal.FC of MOG.L may serve as an objective imaging marker for evaluating hand dysfunction.

Objective: To investigate the clinical efficacy of transurethral 450 nm blue laser vaporization of prostate (BVP) and transurethral plasmakinetic resection of the prostate (PKRP) in the treatment of frail elderly patients with benign prostatic hyperplasia (BPH). Methods: A retrospective analysis was conducted on the clinical data of 62 frail elderly BPH patients undergoing BVP (n=32) or PKRP (n=30) in our hospital during Jan.2023 and Jun.2024.The two groups were compared in terms of postoperative hemoglobin drop, operation time, hospital stay, catheter indwelling time, bladder irrigation time, preoperative and postoperative 3-month postvoid residual (PVR), maximum urinary flow rate (Qmax), international prostate symptom score (IPSS), quality of life score (QoL), and postoperative complications. Results: The postoperative hemoglobin drop was lower in the BVP group than in the PKRP group [(1.62±1.04) g/L vs.(7.37±2.37) g/L, P＜0.001].The operation time [(24.53±7.52) min vs. (47.77±11.12) min], hospital stay [(2.78±1.62) d vs. (8.13±0.82) d], catheter indwelling time [(1.84±0.99) d vs. (5.40±0.81) d], and bladder irrigation time [(7.37±2.35) h vs. (51.60±19.72) h] were significantly shorter in the BVP group than in the PKRP group (all P＜0.001).At 3 months postoperatively, both groups showed significant improvements in IPSS, QoL, Qmax, and PVR compared to preoperative levels (P＜0.05), but there were no significant differences between the two groups (P>0.05).The overall incidence of early postoperative complications in the BVP group was lower than that in PKRP group (18.75% vs. 43.33%, P＜0.05).After 3 months of follow-up, there was no significant difference in the incidence of complications between the BVP group and PKRP group(3.13% vs. 13.33%, P=0.14). Conclusion: BVP for the treatment of frail elderly BPH patients is safe and reliable, associated with minimal bleeding, short operation time, catheterization time and hospital stay, and there is no need to discontinue anticoagulant drugs.

Objective:To explore the feasibility and effect of remote medical education model using online film reading training to improve the ability of ophthalmologists in the Xinjiang Uygur Autonomous Region (hereinafter referred to as "Xinjiang Region" ) in diagnosing fundus diseases.Methods:The three-level film reading training system of Xinjiang Production and Construction Corps system division hospital-Corps Hospital-Peking Union Medical College Hospital was established. From June 2022 to January 2023, 4 159 posterior color fundus images were continuously collected from Department of Ophthalmology of Xinjiang Corps Hospital and 4 divisional hospitals in the Corps medical system. Among them, hypertensive retinopathy, diabetic retinopathy, exudative age-related macular degeneration (AMD), atrophic AMD and retinal vein occlusion were 3 073, 651, 43, 186 and 206 cases, respectively. The images were divided into 3 rounds (first, second and last) according to the proportion of diseases. The doctors who participated in the training (hereinafter referred to as the "training") were 15 ophthalmologists from the Corps Hospital of Xinjiang Region and the division hospital of the Corps system. There were 7 male and 8 female. Age was (38.1±4.0) years. The titles of senior, deputy senior, intermediate and junior are 1, 6, 5 and 3 respectively; Bachelor's degree and master's degree are 13 and 2 respectively. The working time of fundus disease specialty was (9.6±3.3) years. The film reading system training was conducted before the first round of labeling, and after each round of film reading, the doctors of Peking Union Medical College Hospital gave feedback and explanation on the film reading results. The diagnostic consistency, sensitivity and specificity were compared by paired sample t test. Spearman or Pearson correlation analysis was conducted between the improvement of diagnostic level and professional title, education, age and working hours of ocular fundus disease. Results:All the participating doctors completed the first, second and last reading. After each round of film reading, the film reading summary was carried out for 2 hours. The average diagnostic agreement rates of participating physicians were 53.0%, 67.0% and 75.0%, respectively. The sensitivity and specificity were 0.38, 0.69, 054 and 0.66, 0.85, 0.96, respectively. There was significant difference between the first and last examination ( P<0.001). The sensitivity of the second reading was significantly higher than that of the first reading, and the sensitivity of the last reading was significantly lower than that of the second reading, with statistical significance ( P<0.05). The specificity of the second reading was significantly higher than that of the first reading, and the last reading was significantly higher than that of the second reading, with statistical significance ( P<0.05). There was no significant correlation ( P>0.05) between the improvement of diagnostic level of participating physicians and educational background ( Rho=0.07), professional title ( Rho=0.13), age ( r=0.20), and working time of ophthalmofundus disease specialty ( r=0.26). Conclusions:Relying on the three-level online telemedicine training, it can improve the ability of ophthalmologists in Xinjiang region to diagnose fundus diseases. The preliminary telemedicine education model has demonstrated potential for feasibility and effectiveness in remote areas with inadequate medical resources.

Objective:With the in-depth study of complement dysregulation,glomerulonephritis with dominant C3 has received increasing attention,with a variety of pathologic types and large differences in symptoms and prognosis between pathologic types.This study analyzes the clinical,pathological,and prognostic characteristics of different pathological types of glomerulonephritis with dominant C3,aiming to avoid misdiagnosis and missed diagnoses. Methods:The clinical,pathological,and follow-up data of 52 patients diagnosed as glomerulonephritis with dominant C3 by renal biopsy from June 2013 to October 2022 were retrospectively analyzed.According to the clinical feature and results of pathology,15 patients with post-infectious glomerulonephritis(PIGN)and 37 patients with of non-infectious glomerulonephritis(N-PIGN)were classified.N-PIGN subgroup analysis was performed,and 16 patients were assigned into a C3-alone-deposition group and 21 in a C3-dominant-deposition group,or 27 in a C3 glomerulopathy(C3G)group and 10 in a non-C3 nephropathy(N-C3G)group. Results:The PIGN group had lower creatinine values(84.60 μmol/L vs 179.62 μmol/L,P= 0.001),lower complement C3 values(0.36 g/L vs 0.74 g/L,P<0.001)at biopsy,and less severe pathological chronic lesions compared with the N-PIGN group.In the N-PIGN subgroup analysis,the C3-dominant-deposition group had higher creatinine values(235.30 μmol/L vs 106.70 μmol/L,P=0.004)and higher 24-hour urine protein values(4 025.62 mg vs 1 981.11 mg,P=0.037)than the C3-alone-deposition group.The prognosis of kidney in the PIGN group(P=0.049),the C3-alone-deposition group(P=0.017),and the C3G group(P=0.018)was better than that in the N-PIGN group,the C3-dominant-deposition group,and the N-C3G group,respectively. Conclusion:Glomerulonephritis with dominant C3 covers a variety of pathological types,and PIGN needs to be excluded before diagnosing C3G because of considerable overlap with atypical PIGN and C3G;in addition,the deposition of C1q complement under fluorescence microscope may indicate poor renal prognosis,and relevant diagnosis,treatment,and follow-up should be strengthened.
