Objective To discuss the application of mind map in self-management of elderly patients after receiving mitral valve transcatheter edge-to-edge repair(M-TEER).Methods A total of 66 patients,who underwent M-TEER at Nanjing Hospital of Nanjing Medical University from August 2021 to October 2022,were enrolled in this study.Using the envelope concealment method,a total of 66 data analysis samples were included in the analysis.There were 33 patients each in the study group and control group.Routine health education was adopted for the patients of the control group,while the responsible nurse conducted health education for the patients of the study group under the guidance of the mind map that was designed by a multidisciplinary specialized nurses.Results There was a significant difference in postoperative medication compliance between the study group and the control group(P＜0.05),i.e.the degree of compliance,including taking medicine on time,insisting on taking medicine and taking medicine as prescribed,in the study group was obviously higher than that in the control group.The postoperative 6-min walking test,which was regarded as one of the indicators of cardiac functions,in the study group was remarkably better than that in the control group,the difference was statistically significant(P＜0.05).The postoperative quality of life(including daily activity ability,frailty degree,social support,and incidence of hospitalization for heart failure within one year after treatment)in the study group was strikingly better than that in the control group(P＜0.05).Conclusion The use of mind map in self-management of elderly patients after receiving M-TEER can effectively improve the medication compliance of the patients after discharge,improve the quality of life of patients,and reduce the incidence of hospitalization due to heart failure.

Objective To understand the quality of literature of randomized controlled trials( RCTs) on oral hydration for prevention of acute kidney injury after percutaneous coronary intervention published( PCI) in journals in China.Methods Literature of RCTs on oral hydration for prevention of acute kidney injury after PCI published in journals in China was searched in CBM, CNKI, Wan Fang data, and VIP database. And then, they were screened according to the inclusion and exclusion criteria. Besides, the quality of literature was evaluated based on the Cochrane collaboration′s tool for assessing risk of bias and the Jadad scale. Results A total of 10 RCTs were included. The results of the Cochrane collaboration′s tool for assessing risk of bias showed that there was no document to describe whether the data of subjects without completing the trail were analyzed with intentional analysis, random allocation concealment, blinding of participants and outcome assessment and so on. Moreover, the score of Jadad was less than two. There was only one document which mentioned the word‘random’ without involving specific randomized methods, one document which explained the blind method, no document which reported the case that withdrew from the trail and was lost.Conclusions The quality of literature of RCTs on oral hydration for prevention of acute kidney injury after PCI published in journals in China is low. Because of this, high quality researches should be conducted so as to provide good guidance for clinical practice.
