Objective:To explore the psychological experiences of lung cancer patients during treatment based on the perspective of narrative medicine,and to provide references for targeted nursing interventions.Methods:Guided by the concept of narrative medicine,the phenomenological method of qualitative research was used to conduct in-depth interviews with 20 lung cancer patients.The interview data were analyzed,refined,and summarized by using the content analysis method.Results:From the perspective of the humanistic value of narrative medicine,four themes were extracted from the interview contents with 20 lung cancer patients,including the loss of patients'role identity,the experience of disease uncertainty,the fear and expectation of death,and the helplessness and perception of life.Conclusion:During the treatment process of lung cancer patients,there are negative psychological experiences,such as loss of role identity,uncertainty of disease,fear of death,and hope to leave with dignity.Meanwhile,there are positive perceptions,such as contemplation of the meaning of life and actively coping with it.

Objective : Tnfrsf11 a Cre Rosa26 yfp reporter gene mice were prepared to determine the efficiency of Cre-mediated recombination using flow cytometry in different tissue-resident macrophages. Methods : TheTnfrsf11 a Cre Rosa26 yfp reporter mice were generated by crossingTnfrsf11 a Cre mice withRosa26 yfp mice and identified by PCR.Brain microglia, liver macrophages, kidney macrophages, alveolar macrophages and spleen macrophages were separated from adultTnfrsf11 a Cre Rosa26 yfp reporter mouse and yellow fluorescent protein(YFP) labeling efficiency was analyzed by flow cytometry. Results : YFP expression percentage was about 91.27% of brain microglia inTnfrsf11 a Cre Rosa26 yfp reporter mice, but liver, spleen, and alveolar macrophages were inefficiently targeted(63.60%,69.66%,32.76%). Conclusion Tnfrsf11 a Cre mice were qualified as conditional knockout model mice of brain microglia andTnfrsf11 a Cre Rosa26 yfp reporter mice can be used as a tool for conditional knockout of brain microgliain vivo.
