Objective Summarizes the current research status of defensive medicine in China and provides references for future research.Methods The search period spans from the inception of the database to March 2024.CNKI,Wan-fang Data,Web of Science,PubMed databases were queried,followed by literature screening based on predeter-mined inclusion and exclusion criteria.The current landscape of defensive medicine research in China was synthe-sized and categorized based on fundamental research characteristics,measurement methodologies,influencing fac-tors,and other relevant aspects.Results A total of 24 Chinese literature sources and 4 foreign literature sources were incorporated,indicating a prevalent occurrence of defensive medicine in China.Measurement tools for defen-sive medicine exhibit variability across different studies.Key influencing factors encompass doctor's demographic vari-ables such as gender,age,and professional status,institutional factors like legal frameworks and medical in-surance,and sociol-cultural factors such as doctor-patient relationships and adverse public perceptions.Conclusion Defensive medicine is relatively widespread and influenced by various factors in China.It's urgent to explore the for-mation mechanism of defensive medicine from multiple perspectives and provide evidence for passive defen-sive medicine governance.

Objective To clarify the influencing factors of defensive medicine and provide ideas for preventing and re-solving defensive medicine.Methods Literature related to defensive medicine was searched,personnel related to de-fensive medicine were interviewed,and literature and interview data were coded with the method of grounded theo-ry,and related concepts and categories were summarized.Results After three levels of coding,52 initial concepts,23 initial categories,7 sub-categories and 3 main categories were sorted out,and the correlation among influencing factors was analyzed to build a three-dimensional model of"doctor-patient relationship-institutional system-social environment"influencing factors and their mechanism of action.Conclusion The influencing factors of defensive medi-cine mainly include doctor-patient relationship,institutional system and social environment.The three factors have an impact on defensive medicine through different mechanisms of action,which provides qualitative evidence for comprehensive analysis of factors in related studies of defensive medicine.

Objective Based on clinical surgical statistical instances,the influence of double fenestration branch stents on the blood flow field after different depths of implantation in the diseased thoracic aorta was investigated.Methods Thoracic aorta,thoracic aorta-coated stent,and branch vessel-coated stent were established.The finite element calculation method was used to analyze the branch stent implanted into the diseased aorta at different depths(5,10,and 15 mm),and experimental verification was performed using an in vitro tachymetry experimental platform.Results There were certain patterns for maintaining stable perfusion of the blood flow field with branch stent implantation at different depths in the thoracic aorta.The branch blood perfusion rate in Group D10-5(the implantation depths of the left common carotid artery branch stent and left subclavian artery branch stent were 10 mm and 5 mm,respectively)was at a good level,and TAWSSmax was at the lowest level(44.94 Pa),thereby showing the best simulation results.Conclusions When the left subclavian artery branch stent implantation in the thoracic aorta was short,the depth of the left common carotid artery branch stent implantation in the aorta was appropriately increased to obtain a more stable blood flow field.This study provides a theoretical reference for the double-fenestration technique in clinical practice.
