Objective:To evaluate the effects of different exercises on executive function, moter skills and core symptoms in children with attention deficit hyperactivity disorder (ADHD) using network Meta-analysis, and to provide evidence-based basis for the treatment of children with ADHD.Methods:The randomized controlled trails(RCTs)of exercises on children with ADHD were searched in Web of Science, PubMed, Cochrane Library, Embase, PsycINFO, CNKI, Wanfang Data, VIP and CBM databases.The retrieval time limit was from the establishment of each database to May 2023.The Cochrane quality review manual was used to evaluate the quality of the included literatures.Stata 17.0 software was used to perform network Meta-analysis.Results:Finally, twenty-four studies were enrolled including five types of exercise intervention, such as aerobic exercise, multicomponent exercise, exergaming, high intensity interval training (HIIT) and traditional low-to-moderate intensity exercise therapy (TRAD).The results of network Meta-analysis showed that: in terms of improving executive function(working memory, inhibitory control, and cognitive flexibility), motor skills and core symptoms of children with ADHD, the optimal exercise intervention was aerobic exercises (surface under the cumulative ranking were 78.9%, 73.0%, 88.7%, 77.9% and 69.9% respectively).Conclusion:Exercises can improve executive function, improve motor skills, and alleviate ADHD core symptoms.Aerobic exercise has a better effect on improving executive function, motor skills and core symptoms of ADHD children.

Objective:To explore the application status, research hotspots and frontiers of blended teaching mode in undergraduate nursing education at home and abroad, so as to provide reference for related research.Methods:In Chinese, CNKI, Wanfang Database and VIP, and in English, Web of Science database were used as search sources. CiteSpace was used to conduct a quantitative analysis of the retrieved literatures published from 2008 to 2022.Results:A total of 43 literatures in Chinese and 83 in English were retrieved, and the number of publications showed an overall increasing trend. The research hotspots in China focused on education reform, online learning and curriculum system evaluation, and the research frontiers were network teaching, moral education and humanistic care. Foreign research focused on the choice of education model and emphasizes interaction, and the research frontier were to carry out innovative blended teaching and pay attention to the learning experience and learning environment construction of nursing students.Conclusions:In the future, blended teaching should pay attention to carrying out innovative research and dynamic evaluation and feedback of students' satisfaction. In particular, it is necessary to strengthen the cultivation of blended learning competence among nursing teachers, aiming to promote the knowledge and skills of nursing students, and continuously optimize and innovate the application of blended learning in the field of undergraduate nursing education.

In recent years, the development of bispecific antibodies (bsAbs) has been rapid, with many new structures and target combinations being created. The boom in bsAbs has led to the successive issuance of industry guidance for their development in the US and China. However, there is a high degree of similarity in target selection, which could affect the development of diversity in bsAbs. This review presents a classification of various bsAbs for cancer therapy based on structure and target selection and examines the advantages of bsAbs over monoclonal antibodies (mAbs). Through database research, we have identified the preferences of available bsAbs combinations, suggesting rational target selection options and warning of potential wastage of medical resources. We have also compared the US and Chinese guidelines for bsAbs in order to provide a reference for their development.
