Copper is one of the essential elements in the human body,playing various physiological roles.Maintai-ning copper homeostasis is crucial for health.Recent researches have uncovered that copper homeostasis imbalance is closely associated with the occurrence,progression,prognosis,and drug resistance of gynecological malignancies.The employment of copper and its complexes in antitumor therapy has emerged as a promising novel approach,attracting considerable research attention.Based on the relationship between copper homeostasis imbalance and gynecological tumors,this paper provides a concise review of the current status and progress of copper and its complexes in the treat-ment of gynecological tumors.

Rho proteins and the Rho-associated protein kinase(ROCK)signaling pathway are cruci-al components of intracellular signaling cascades.Rho proteins,which belong to the small GTPase family,play a pivotal role in regulating essential elements of the cytoskeleton within cells.ROCK functions as a downstream effector protein kinase of Rho,modulating various biological processes,including cell morphology,migration,and proliferation.Recent studies have underscored the signifi-cance of the ROCK signaling pathway in the replication of a diverse group of viruses.Furthermore,it has been discovered that some viruses disrupt cellular contraction,adhesion,and migration through the Rho/ROCK pathway,subsequently influencing the immune response triggered by vi-ral infections and affecting the tight junctions between cells.This article primarily reviews the re-search progress regarding the Rho/ROCK signaling pathway and its key signaling molecules,Rho and ROCK,in terms of their activation and regulation of viral replication and tight junction pro-teins between cells.

Objective To investigate the effect of serum expression of immune-related guanosine triphosphatase M(IRGM)and Syndecan-1levels in patients with acute ST-segment elevation myocardial infarction(ASTEMI)on the prognosis after percutaneous coronary intervention(PCI).Methods 135 patients with ASTEMI admitted to Suzhou Jiulong Hospital of Shanghai Jiaotong University School of Medicine from January 2021 to January 2023(ASTEMI group)were selected and divided into the poor prognosis group(n=37)and the good prognosis group(n=98)after PCI treatment for 3 months,and 65 physically examined and healthy people(control group)were also selected during the same period.The enzyme-linked immunosorbent assay(ELISA)was used to detect serum IRGM,Syndecan-1 levels,Logistic regression was used to analyze the influencing factors of poor prognosis after PCI in ASTEMI patients,and receiver operating characteristic(ROC)curves were plotted to evaluate the predictive value of serum IRGM,Syndecan-1 levels on poor prognosis after PCI in ASTEMI patients.Results Compared with the control group,serum IRGM(6.17±2.50 ng/ml vs 2.59±0.94 ng/ml),Syndecan-1(420.97±123.65 ng/ml vs 278.89±43.06 ng/ml)levels were higher in the ASTEMI group,and the differences were statistically significant(t=14.628,11.932,all P<0.001).During a three-month follow-up,the incidence of poor prognosis after PCI in 135 patients with ASTEMI was 27.41%(37/135).The age,proportion of KILLIP grade≥II,Gensini score,white blood cell count,LDL-C,IRGM and Syndecan-1 levels in the poor prognosis group were higher than those in the good prognosis group,and the LVEF scores was lower than those in the good prognosis group,and the differences were statistically significant(χ2/t/Z=2.119～8.042,all P<0.05).Independent risk factors for poor prognosis after PCI in patients with ASTEMI were KILLIP classification≥II,high Gensini score,high IRGM,high Syndecan-1,and high LVEF were the independent protective factors(Wald χ2=4.225～11.413,all P<0.05).The AUC(95%CI)of serum IRGM combined with Syndecan-1 level in predicting poor prognosis in patients with ASTEMI after PCI was larger than that of IRGM,and Syndecan-1 alone predictsed poor prognosis,and the differences were statistically significant(Z=3.400,2.905,all P<0.05).Conclusion High serum IRGM,Syndecan-1 level is an independent risk factor for poor prognosis after PCI in pa-tients with ASTEMI,and the combination of serum IRGM,Syndecan-1 level has a high predictive value for it.

Objective:To explore the mediating role of cyber self-efficacy between technological anxiety and the willingness to use tele-rehabilitation among patients with chronic obstructive pulmonary disease (COPD) .Methods:From September 2023 to May 2024, a convenience sampling method was used to select COPD patients receiving treatment in the Inpatient Department of Zhoushan Hospital as the research subjects. A General Information Questionnaire, the Scale of Willingness to Use Tele-Rehabilitation for COPD Patients, the Technological Anxiety Scale, and the Cyber Self-Efficacy Questionnaire were used to collect data.Results:A total of 312 questionnaires were distributed, and 305 valid questionnaires were retrieved, with an effective recovery rate of 97.76%. The average score of the Scale of Willingness to Use Tele-Rehabilitation for the 305 COPD patients was (76.52±5.30) , and the average item score was (2.94±0.20) . Cyber self-efficacy played a partial mediating role between technological anxiety and the willingness to use tele-rehabilitation, accounting for 8.21% of the total effect (-0.048/-0.585) .Conclusions:The level of willingness to use tele-rehabilitation among COPD patients needs to be enhanced. The professional values of COPD patients not only directly affect their level of willingness to use tele-rehabilitation, but also influence their technological anxiety, which in turn affects their cyber self-efficacy, ultimately having an indirect impact on the willingness to use tele-rehabilitation. Nursing staff should strengthen the professional values of COPD patients, help them overcome technological anxiety, and enhance their cyber self-efficacy, so as to increase their willingness to use tele-rehabilitation.

After ostomy surgery, patients lose the ability to control their anal sphincter, relying on ostomy pouches for excretion. Convex baseplates offer several advantages, including preventing leakage, reducing the risk of stoma and peripheral skin complications, and adapting to the dynamic stoma shapes caused by peristaltic expansion and contraction of the stoma. This article reviews the structure and features of convex baseplates, usage considerations, existing challenges, and future prospects, aiming to provide a reference for the standardized clinical use of convex baseplates and to improve patient health outcomes.

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.
