Objective: To analyze the association of sedentary types with symptom of depressive and anxiety among college freshmen, so as to provide a reference for improving the mental health of college students. Methods: From October to November 2022, all college freshmen at three colleges and universities in Anhui Province were selected by a cluster sampling method. The Generalized Anxiety Disorder-7 (GAD-7), the Patient Health Questionnaire-9 (PHQ-9), and the Youth Leisure-Time Sedentary Behavior Questionnaire (YLSBQ) were used for the investigation. A binary Logistic regression analysis was conducted to investigate the relationship of different types of sedentary behavior with anxiety and depressive symptom. Results: The detection rates of anxiety and depressive symptom among college freshmen were 32.8% and 49.9%, respectively. The results of the binary Logistic regression model analysis showed that after controlling for gender, family location, parental education level, self rated family economic status and number of intimate partners, high level overall, video based, and social based sedentary time were associated with an increased risk of anxiety ( OR =1.26, 1.56, 1.27) and depressive symptom ( OR =1.42, 1.94, 1.29) among college freshmen; the association between moderate level sedentary time and depressive symptom was statistically significant ( OR =0.83) (all P <0.05). The overall trends of the association between sedentary behavior with symptom of anxiety and depressive were similar in both boys and girls. Conclusions Sedentary behavior is associated with an increased risk of anxiety and depressive symptom in college students. Reducing video based and social based sedentary behaviors is beneficial for mental health promotion in college students.

The classification of stoma skin barriers varies based on their specific features. The curvature design of convex skin barriers provides a secure and effective seal for patients with flat, retracted stomas or peristomal skin folds. The secure sealing ability of convex skin barriers is attributed to several critical structural components. Although convex skin barriers offer many clinical advantages, there is currently no unified standard for measuring their characteristics, resulting in confusion among healthcare professionals when selecting stoma care products. To address this issue, the 2021 International Stoma Care Expert Meeting proposed the Expert Consensus on Characteristics of Convex Skin Barriers and Clinical Application, which clearly defines five essential properties and clinical application guidelines for convex barriers. However, as most consensus contributors are from Europe and North America, its applicability in Chinese healthcare settings may be limited. Therefore, this paper provides a detailed interpretation of the five characteristics and clinical application statements of convex skin barriers, aiming to offer practical guidance to clinical nurses in selecting appropriate convex products and managing stoma-related complications.

To summarize the nursing experience of 3 patients with severe hypercapnia during the acute exacer-bation of chronic obstructive pulmonary disease(COPD)undergoing extracorporeal carbon dioxide removal(ECCO2R),as well as adjustment of oxygen therapy support strategy and implementation of non-pharmacological airway clearance techniques.Additionally,the nursing focus includes all process nursing of ECCO2R,which covers the key aspects such as catheter selection and placement management,pre-flush setting and bubble handling,dual connection with initial parameter setting for patients,heparin pathway management and bleeding monitoring,observation of thrombosis formation and pressure monitoring during operation and self-examination,evaluation of carbon dioxide removal effi-ciency and implementation of decommissioning tests.After careful treatment and nursing,2 patients recovered and were discharged,and a patient's condition improved and was transferred to the respiratory ward for further treat-ment,and was discharged after 5 days.

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.

Abstract Increasing attention has been paid to the relationships between the natural environment and psychological problems among children and adolescents. The article reviews research, conducted in China and other countries, examining the relationships between natural environmental factors-such as green space, air pollution, climate change, noise, and psychological problems among children and adolescents, to enhance understanding of these relationships and their possible underlying biological mechanisms. The findings may provide a reference for promoting mental health in children and adolescents.

Objective: To understand the association of maternal emotional symptoms and parent-child relationship with emotional and behavioral problems (EBPs) in primary school students, so as to provide a reference for the prevention of EBPs in primary school students. Methods: In May 2023, a convenient cluster sampling method was used to select 1 324 students from two primary schools in Hefei City, Anhui Province as the study subjects. The Generalized Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire (PHQ-9), Family Adaptation and Cohesion Evaluation ScalesⅡ (FACES Ⅱ), and Strengths and Difficulties Questionnaire (SDQ) of parental version were used to investigate maternal emotional symptoms, parent-child relationship, and EBPs of primary school students, respectively. Multivariate Logistic regression analysis model was used to analyze the association of different maternal emotional symptoms and parent-child relationship with EBPs of primary school students. Results: The abnormal detection rates of emotional symptoms, conduct problems, hyperactivity disorder, peer problems, prosocial behavior and total difficulties in primary school students were 13.6%, 19.4%, 20.2%, 36.5%, 20.9% and 51.9%, respectively. Multivariate Logistic regression analysis showed that the detection rates of EBPs in primary school students whose mothers had anxiety and depression symptoms with low level of parent-child relationship increased ( OR=1.52-6.97, P <0.01). The combined effect of mothers who had anxiety and depression symptoms with low level of parent-child relationship increased the risk of EBPs in all dimensions of primary school students ( OR=4.07-10.14, P <0.01). After gender stratification, the combined effect of mothers who had anxiety and depression symptoms with low level of parent-child relationship increased the risk of EBPs in all dimensions of boys and girls ( OR=3.71- 10.95 , P <0.01). Conclusions Maternal emotional symptoms and parent-child relationship are associated with EBPs in primary school students. Reducing maternal anxiety and depression symptoms, and improving parent-child relationship are beneficial to reduce the incidence of EBPs problems in primary school students.

Objective: To explore the mediating effect and gender difference of mobile phone use in the association between different types of childhood abuse experiences and sleep quality of medical students, so as to provide reference for promoting sleep quality of medical students. Methods: A longitudinal study design method was used to select freshmen and sophomores in two medical colleges in Anhui Province from November to December 2019, follow up data were collected from May to June 2020, and a total of 6 879 students were included in this study. Spearman correlation was used to analyze the association between baseline childhood abuse experiences, baseline mobile phone use and follow up sleep quality. Bootstrap program and Process software were applied to test the mediating effect of mobile phone use in the relationship between childhood abuse and sleep quality. Results: Childhood abuse experiences were positively correlated with mobile phone use and sleep quality score ( r = 0.27 , 0.24, P <0.01), and mobile phone use was positively correlated with sleep quality score ( r =0.31, P <0.01). In the total sample, after adjusting for confounding factors, mobile phone use played a partial mediating role in childhood abuse experiences (including emotional abuse, physical abuse, sexual abuse) and sleep quality, and the mediating effect was 18.08% (18.12%, 17.15%, 24.09%). The mediating effect of mobile phone use on the relationship between childhood emotional abuse, sexual abuse, childhood abuse and sleep quality in girls(18.32%, 28.05%, 18.24%) was higher than in boys(17.81%, 18.94%, 17.63%). Conclusion Mobile phone use has a mediating effect on the relationship between childhood abuse and sleep quality, controlling mobile phone overuse may contribute to improving the sleep quality for those who have experienced childhood abuse.
