Objective To measure the urethral meatus circumference in middle-aged and elderly males to undergo surgery for benign prostatic hyperplasia (BPH), and to collect data for developing endoscopic equipment suitable for the male urethra in China. Methods Clinical data were collected from patients (aged ≥50 years) who underwent transurethral resection of prostate in the First Affiliated Hospital of Xi'an Jiaotong University during Jan. and Dec. 2024. All patients had the urethral meatus circumference measured with a metal urethral probe before surgery, followed by the use of a F26.5 endoscopic sheath for surgery. The passage of urethral meatus using different types of metal urethral probes were observed. Results For the 183 patients, the types of endoscopic sheath smoothly passing through the urethral meatus were distributed as follows:42 cases (22.95%) with F26 or above, 66 cases (36.07%) with F25-26, 27 cases (14.75%) with F23-24, 26 cases (14.21%) with F21-22, 22 cases (12.02%) with F20 or below, and the smallest was F17 (1 case). Of all patients, 59.02% (108/183) were able to insert the F26.5 endoscopic sheath smoothly into the urethral meatus (≥F25), 28.96% (53/183) required force or urethral dilation before inserting (F21-F24), and 12.02% (22/183) needed to open the urethral meatus before inserting the endoscopic sheath (≤F20). Conclusion When the most common F26.5 endoscopic sheath is used, 40.98% of the patients have the possibility of urethral injury, which is significantly too big for male transurethral surgery. For patients undergoing transurethral BPH surgery, a thinner sheath should be used to reduce the possibility of urethral injury and secondary iatrogenic urethral stricture.

Objective To explore the clinical value of preoperative assessment and intraoperative frozen section pathology in screening patients suitable for testicular preservation surgery, so as to provide reference for reducing unnecessary radical orchiectomy in patients with benign testicular tumors. Methods A retrospective analysis was conducted on 121 patients who underwent surgical treatment for testicular tumors in the First Affiliated Hospital of Xi'an Jiaotong University during Jan. 2021 and Sep. 2025. Data were collected, including demographic information, preoperative imaging, serum tumor markers, surgical procedures, intraoperative frozen section, postoperative pathology, and postoperative testicular volume changes. Results Among the 121 patients, 105 underwent radical orchiectomy, with 91 malignant and 14 benign cases confirmed by postoperative pathology; 16 received testicular tumor enucleation, all confirmed as benign. Benign lesions accounted for 24.79% (30/121) of all cases. In patients undergoing tumor enucleation, intraoperative frozen section results were fully consistent with final pathological findings. Conclusion Preoperative differentiation between benign and malignant testicular tumors is crucial for selecting the appropriate surgical approach. For patients with preoperative findings suggesting benign lesions, testicular tumor enucleation combined with intraoperative frozen section can achieve precise treatment while maximizing testicular preservation.

The Party branch constitutes the most grassroots organization of the Communist Party of China(CPC)in uni-versity-affiliated hospitals.This study preliminarily analyzes the current configuration of Party branches,clarifies the concept of joint building,and delineates its significance for hospital governance.Drawing on our institutional experience,we summarize the"1+1"joint-building model from two perspectives—intra-hospital and extra-hospital collaboration—covering administrative branch joint building,clinical branch joint building,faculty-student branch joint building,and joint building with primary-lev-el hospital branches.The findings offer a replicable framework and practical reference for strengthening Party construction in pub-lic hospitals.

Objective:To explore the the possibility and potential mechanism of Coptis chinensis in treating caries based on network pharmacology and molecular docking technology.Methods:The active ingredients of Coptis chinensis and the targets of the active in-gredients and caries were obtained through a variety of databases.The intersection targets of Coptis chinensis and caries were obtained by VENNY.Based on the target of the intersection,the protein-protein interaction(PPI)networks relationship diagram was formed on the STRING platform.The core target diagram was formed through the Cytoscape software,and the Coptis chinensis-active ingre-dient-target network diagram was constructed.The intersection targets are analyzed by GO and KEGG.The core targets of Coptis chinensis active ingredients in treating caries was analyzed by molecular docking.Results:The 11 Coptis chinensis active ingredi-ents,465 targets of Coptis chinensis active ingredients and 1 160 targets of caries were obtained from the database.After analysis,71 targets of Coptis chinensis-caries intersection and 12 core targets were obtained.The potential therapeutic effect of Coptis chinensis on caries involved relaxin,phosphatidylinositol 3-kinase-protein kinase B(PI3K-Akt),mitogen activated protein kinase(MAPK),ras-re-lated protein 1(RAP1)and other signaling pathways.Berberine,one of the main active components of Coptis chinense,had strong binding activity on epidermal growth factor receptor(EGFR),matrix metalloproteinase 9(MMP9)and other core targets.Coptis chinen-sis and its active components can play a role in the treatment of caries through EGFR,MMP9 and PI3K-AKT,MAPK and other path-ways.Conclusion:Coptis chinensis and its active components can regulate several targets and signaling pathways such as EGFR,MMP9,PI3K-AKT and MAPK.Coptis chinensis may play a role in the prevention and treatment of caries through multiple pathways.

Objective::To evaluate the diagnostic efficacy and clinical application of the Obstetrical Chinese Disseminated Intravascular Coagulation (DIC) Scoring System (OCDSS).Methods::This study is a retrospective study that collected 1063 cases from Wuhan Union Hospital, Yichang Central People’s Hospital, and the Central Hospital of Enshi Tujia and Miao Autonomous Prefecture between July 2017 and June 2024. These cases were divided into DIC and non-DIC groups based on score standard. Diagnosis of DIC, the rate of hysterectomy, neonatal mortality, and severe asphyxia are the main outcome measures. All the laboratory indicators are all determined by clinical laboratory department of the hospital. Data were expressed as mean ± standard deviation or median (interquartile range) and frequencies. Independent sample t-test or non-parametric test were used to compare measurement data, while the chi-square test was used for count data. Receiver operating characteristic (ROC) curve and area under curve (AUC) were used to test the predictive accuracy. Using univariate and multivariate logistic regression analysis to study the high-risk factors. P < 0.050 indicates a statistical significance. Results::Of 1063 participants in this study, 29 participants (2.73%) were diagnosed with obstetrical DIC by OCDSS score standard, and all the participants were diagnosed as DIC with underlying disease. When the Takao, Clark, and Erez score standard is the "gold standard", the OCDSS score standard always shows good sensitivity and specificity, with all the AUC over 0.75. OCDSS score standard also has better predictive of hysterectomy (68.18%, 91.07%, 0.872), severe neonatal asphyxia and death (79.17%, 75.07%, 0.842) than the other three score standards. All the indicators included in the OCDSS score standard contributed to the DIC diagnosis (all the P < 0.001). The indicators in the DIC group were more abnormal than the non-DIC group (all the P < 0.001). Conclusion::OCDSS is a first score standard, especially for pregnancies, it considers the underlying disease, clinical symptoms, and laboratory results. This score system shared a good diagnosis performance for DIC in the Chinese population and may help clinicians make timely decisions.

Objective:To explore the difficulties and needs of wound ostomy incontinence specialist nurses when applying convex baseplates, with the aim of providing a basis for standardizing ostomy care.Methods:Purposeful sampling was used to select 13 wound ostomy incontinence specialist nurses from tertiary hospitals in Hebei, Jilin, Hunan, Beijing, and Tianjin for semi-structured interviews between November and December 2024. Content analysis was used to analyze the data.Results:Two main themes were identified: application dilemmas and application needs. Application dilemmas included four subthemes: insufficient understanding of convex baseplate characteristics, unclear indications and contraindicated populations, lack of unified standards for assessment timing, and inadequate awareness of health education. Application needs included two subthemes: urgent need for related evidence-based evidence and a desire for clinical guidelines and expert consensus.Conclusions:Currently, wound ostomy incontinence specialist nurses in China face challenges in understanding the characteristics of convex baseplates, scope of application, identifying contraindications, determining the optimal timing for application assessment, and providing patient education. Administrators should develop clinical application standards for convex baseplates based on these challenges. Furthermore, researchers should develop relevant clinical guidelines or expert consensus for convex baseplate application in China, providing a basis for the standardized use of ostomy care products.

Objective:To investigate the current status of convex baseplate selection and use among clinical nurses.Methods:A convenience sampling method was employed to survey 1 873 nurses from 180 hospitals across China between November and December 2024 using a general information questionnaire and a self-designed questionnaire on convex baseplate selection and use. A total of 1 873 questionnaires were distributed, and 1 860 valid responses were collected, yielding a response rate of 99.31% (1 860/1 873) .Results:Among the 1 860 nurses, 88.98% (1 655/1 860) had access to convex baseplates in clinical practice. However, only 8.82% (146/1 655) used them immediately postoperatively, and only 4.53% (75/1 655) chose convex baseplates without considering any product features. The five common clinical indications for convex baseplate use included stoma retraction (96.62%, 1 599/1 655) , peristomal skin folds or depressions (96.56%, 1 598/1 655) , flush stomas (80.12%, 1 326/1 655) , leakage (70.03%, 1 159/1 655) , and abdominal laxity (66.89%, 1 107/1 655) . Common contraindications for use included peristomal varicose veins (77.46%, 1 282/1 655) , peristoma pressure injuries (75.35%, 1 247/1 655) , stoma prolapse (74.50%, 1 233/1 655) , parastomal hernia (72.87%, 1 206/1 655) , and pyoderma gangrenosum (67.01%, 1 109/1 655) . Key assessment areas when selecting convex baseplates included the stoma itself (97.28%, 1 610/1 655) , peristomal skin (96.50%, 1 597/1 655) , abdominal wall contour (95.41%, 1 579/1 655) , excretion patterns (87.37%, 1 446/1 655) , and previous convex baseplate use (82.36%, 1 363/1 655) . Measures commonly used by nurses to enhance adhesion included the use of stoma belts (95.29%, 1 577/1 655) , barrier rings or paste (94.80%, 1 569/1 655) , smoothing peristomal skin folds (90.57%, 1 499/1 655) , advising patients to limit bending (82.96%, 1 373/1 655) , and abdominal binders (57.28%, 948/1 655) .Conclusions:The clinical application of convex baseplates requires further promotion. Nursing administrators should strengthen training on the selection, characteristics, and indications of convex baseplates, with particular emphasis on the understanding of the five key product features.
