Objective To investigate the coping style and influencing factors of the recipients after relative kidney transplantation. Methods Medical coping modes questionnaire (MCMQ) and observa-tion interview were performed in the sampling survey, 56 case of recipients after relative kidney transplanta-tion according to the adopted standard were analyzed. Results The confronting score of all the cases were close to that of normal model, but the avoiding score and yielding score significantly increased. The prospective health conditions of the relative donors, function and survival time of the graft kidney, rejection reaction and other complication after transplantation were the main factors affecting the coping style of the recipients. Conclusions Based on the accurate evaluation of the coping style, nursing intervention should be aimed at the recipients following relative riving donor kidney transplantation, in order to help the recipients create a correct coping style and improve the survival rate of patient/kidney.

Currently,revascularization is an effective rescue strategy for patients with acute myocardial infarc-tion.However,myocardial ischemia/reperfusion(I/R)injury induced by revascularization has become a significant risk factor affecting the long-term prognosis of patients with ischemic cardiomyopathy after revascularization,without precise treatment.Extracellular vehicles derived from mesenchymal stem cells are characterized by easy access,editability,and easy absorption of cells,and their application in treating myocardial I/R injury is considered valuable to study.This review focuses on the advances in research on mesenchymal stem cell-derived extracellular vehicles and their function of regulating myocardial I/R injury after natural drug intervention,hopefully offering ideas for the research of prevention and treatment of myocardial I/R injury.
