Because a large portion of hearing impairment involves loss of hair cells, regeneration or replacement of these cells is a possible alternative to prosthetic devices1. Researchers have paid hot attention to the study of inner ear hair cell regeneration for hearing restoration for many years. Besides the important function of hair cells, there are many other contributors essential for normal hearing. Hair cell regeneration is one of the essential steps for total hearing recovery, but not the only one. In this article, we will review the progresses in research on hearing loss, stem cell application and hearing restoration.展开更多

文摘Neutrophil extracellular traps(NETs)have been the subject of research in the field of innate immunity since they were first described two decades ago.NETs are fibrous network structures released by neutrophils under specific stimuli,including DNA,histones,and a variety of granular proteins.NETs have been widely studied in the fields of infectious and immune diseases,and new break-throughs have been made in the understanding of disease pathogenesis and treatment.In recent years,studies have found that NETs play an important role in the occurrence and development of osteoarticular diseases.This article reviews the progress in the research of NETs in common osteoarticular diseases such as rheumatoid arthritis,ankylosing spondylitis,gouty arthritis,osteonecrosis of the femoral head,osteoarthritis,and joint fibrosis,including the formation mecha-nism of NETs and its role in inflammation,joint destruction,pain and other pa-thological processes.The problems existing in current research are discussed,along with future research directions,to provide a reference for the in-depth study of osteoarticular diseases and the development of new treatment strategies.
文摘Suicide is a major and urgent issue in the field of mental health,and the United Nations has set“reducing global suicide mortality by one third by 2030”as one of its sustainable development goals.Suicide literacy refers to an individual’s ability to recognize,manage,and prevent suicide-related problems.This article offers a comprehensive review of the concepts,assessment tools,factors,and interventions of suicide literacy,with the goal of helping individuals to better understand suicidal behaviors and providing a scientific basis for developing effective suicide prevention strategies and measures to advance the progress of suicide prevention.

文摘Oncology covers a wide range of knowledge and is more difficult compared to other clinical disciplines.Therefore,it is crucial to seek an efficient teaching method for oncology education.In recent years,China’s internet technology has achieved rapid development.Massive Open Online Course(MOOC),a blended learning approach based on internet technology,has strong applicability to medical education.It can not only improve teaching quality but also promote further reform of the discipline.Based on this,our study searched for relevant research at home and abroad and reviewed the implementation path of integrating MOOC and blended learning in oncology education.This provides a theoretical foundation for the innovation of oncology teaching models,improves the level of oncology teaching,and lays a solid foundation for talent reserves in oncology departments.

文摘Nursing students often exhibit emotional suppression,avoidance,or over-expression when confronted with high-pressure work environments and emotional challenges.These disorders affect nursing students mental health,professional adaptation,and quality of communication with patients.The causes of emotional expression difficulties include individual personality,emotional intelligence,educational background,and socio-cultural pressures.To address this issue,it is recommended to enhance nursing students emotional expression and regulation capabilities through psychological interventions,emotional intelligence training,and optimization of educational systems,thereby improving their mental health and career development,ultimately enhancing nursing service quality and doctor-patient relationships.
文摘With the iteration and upgrading of medical technology and the continuous growth of public health demands,the quality of nursing services has become a core indicator for measuring the effectiveness of the medical system.The clinical practice ability of nursing staff is directly related to the safety of patient diagnosis and treatment and the rehabilitation process.However,the current clinical nursing talent training model is facing bottlenecks such as limited practical scenarios and fragmented case cognition.This study focuses on the teaching application of augmented reality(AR)technology in hospital Settings and systematically reviews the research progress on the improvement of clinical practice ability of trainee nurses based on the AR immersive teaching model.By constructing a clinical teaching scenario that integrates virtual and real,AR technology can dynamically simulate complex case handling processes and enhance nursing students’three-dimensional cognition of condition assessment,operation norms,and emergency plans.Hospitals,as the core base for practical teaching,can effectively shorten the connection cycle between theoretical teaching and clinical practice by integrating AR technology,improve the clinical practice level of trainee nurses,and provide an innovative model for optimizing the path of clinical nursing talent cultivation.
文摘Atherosclerosis(AS)is the core pathological basis of Cardiovascular Disease(CVD)worldwide.Its occurrence and development involve endothelial dysfunction,lipid deposition,chronic inflammation and abnormal proliferation of smooth muscle cells.Berberine(BBR),also known as berberine,is an isoquinoline alkaloid extracted from traditional Chinese medicine such as Coptis coptidis and Phelloberia angustifolia.It has traditionally been used for antibacterial and anti-inflammatory treatment.In recent years,it has been found that it has multi-target metabolic regulation and anti-inflammatory properties,showing significant potential in the prevention and treatment of AS.This article systematically reviews the research progress of berberine in the treatment of AS by improving endothelial function,regulating lipid metabolism,inhibiting inflammatory response,regulating smooth muscle cell phenotypic transformation,and anti-oxidative stress,and discusses the current status and challenges of its clinical application.
文摘Nursing care during the perioperative period of thyroid cancer plays a crucial role in the recovery of patients.With the development of medical technology,Western medicine nursing techniques have matured in the perioperative period,including preoperative risk assessment and airway management,intraoperative neuromonitoring nursing coordination,postoperative drainage,and incision management.However,single Western medicine nursing often cannot fully meet the multifaceted needs of patients,especially in emotional nursing and the management of postoperative adverse reactions.The involvement of traditional Chinese medicine nursing techniques provides an effective complement to nursing work.Through integrated Chinese and Western medicine nursing,it is possible not only to improve patients’preoperative anxiety and postoperative nausea and vomiting but also to effectively manage postoperative pain,enhancing the overall comfort and recovery speed of patients.
