Objective To retrieve，extract，evaluate，and integrate the relevant evidence of postoperative pulmonary rehabilitation management in patients with lung cancer complicated with chronic obstructive pulmonary disease，so as to provide an evidence-based basis for improving the quality of postoperative pulmonary rehabilitation. Methods Relevant literature on postoperative pulmonary rehabilitation of lung cancer complicated with chronic obstructive pulmonary disease were searched by computer from clinical decisions，guideline websites，professional association websites，and comprehensive databases. The types of the literature included clinical decisions，guidelines，expert consensuses，evidence summaries，systematic reviews，meta-analyses，and randomized controlled trials. The retrieval time limit was from the establishment of the database to September 2023. Results A total of 19 articles were included，including 4 clinical decisions，3 guidelines，6 expert consensuses，1 evidence summary，3 systematic reviews，and 2 randomized controlled trials. Through reading，extraction and classification，23 pieces of best evidence were finally formed，including multidisciplinary cooperation，evaluation，pulmonary rehabilitation strategies and health education. Conclusion This study summarizes the best evidence for postoperative lung rehabilitation management in patients with lung cancer and chronic obstructive pulmonary disease. Clinical medical staff can implement practical evidence for postoperative lung rehabilitation based on actual situations，and promote the transformation of evidence-based knowledge into practice.

Objective To investigate the application of best evidence for phase I cardiac rehabilitation in transcatheter aortic valve replacement（TAVR） patients into clinical practice and to evaluate its effectiveness. Methods The best evidence for phase I cardiac rehabilitation in patients with TAVR was summarized using an evidence-based care approach,and an evidence-based practice protocol was developed. The best evidence application strategy was constructed after a baseline review and analysis of barriers,and it was implemented in the cardiology department of a tertiary care hospital in Zhejiang Province from September 30 to December 31,2020. The indicators of patients before and after the application of evidence and the implementation rate of the reviewed entries were compared. Results The length of stay of patients after TAVR was shortened from 5（1,7） d at the baseline review to 3（1,6） d（P=0.016）. The percentage of cardiac function of New York Heart Association（NYHA） class I at 30 days postoperatively increased from 31.63% to 72.09%（P<0.001）,and the Katz index also improved（P=0.032）. After the application of best evidence,the rates of review indicators increased from 0~77.55% to 59.30%~100%,with a statistically significant difference（P<0.001）. Conclusion Best evidence application for phase I cardiac rehabilitation in patients undergoing TAVR can shorten patient length of stay,improve patient clinical outcomes,and standardize nurse behaviors.

To conclude the nursing experience of a case of pregnancy with myasthenia gravis pre-crisis state. Main nursing points include：to strengthen the observation，early identification of myasthenia before crisis state，to strengthen incentive care for the prevention of myasthenia crisis；to conduct phased implementation of respiratory rehabilitation nursing；to strengthen health guidance to prevent disease recurrence. The patient was hospitalized for 29 days，with no occurrence of myasthenia crisis. The dyspnea was significantly improved，and the patient recovered and was discharged.
