Objective To investigate the influencing factors of compassion fatigue（CF） among nurses in maternity hospitals,and then to further explore the impact path of factors. Methods 715 nurses in maternity hospitals from Jiangsu were investigated by the cross-sectional survey. A self-developed questionnaire,the Five-Factor Inventory,the Social Support Rate Scale,the Psychological Capital Questionnaire-Revision,and the Compassion Fatigue Scale were adopted to collect data. Results The number of children,personality of neuroticism and agreeableness,social support,and psychological capital are the influencing factors of CF（P<0.05）,while professional titles,length of services,labor relations,personality of extraversion and openness,social support and psychological capital influence compassion satisfaction（CS）（P<0.05）. In structural equation model,the indirect effects of neuroticism on CF or CS existed（ES=0.062,-0.420）. Social support and psychological capital play a partially mediating role in neuroticism and CF（ES=0.017）,accounting for 27.42% of the total indirect effects. They also play a completely mediating role in neuroticism and CS（ES=-0.112）,accounting for 26.67%. Positive personality had a significant indirect effect on CF or CS（ES=-0.158,0.623）,and social support and psychological capital serve as a completely mediating role between them （ES=-0.028,0.102）,accounting for 17.72% or 16.37% of the total indirect effects. Conclusion Nursing managers should take effective measures tailored to personality traits to help nurses meet high levels of social support and psychological capital,so as to promote CS and reduce CF.

Objective To retrieve，evaluate and summarize the best evidence of non-pharmacological interventions for maternal postpartum depression and to provide references for clinical practice. Methods According to the top-down principle of the evidence-based resource 6S model，a systematic search of domestic and foreign databases and websites was conducted on the intervention of postpartum depression，including relevant clinical decision reports，best practices，guidelines，evidence summaries，systematic reviews，and expert consensuses. The search time limit was from the establishment of the databases to March 2022. A supplementary search was performed for randomized controlled trials published between September 2019 and March 2022. There were 2 researchers who evaluated the quality of the literature，extracted and summarized the evidence according to the subject. Results Totally 15 articles were involved，including 1 best practice，3 guidelines，2 expert consensuses and 9 systematic reviews. Finally，28 pieces of best evidence about iatrophysics，psychological interventions，exercise interventions，other interventions，and intervention implementation and monitoring were summarized. Conclusion Non-pharmacological interventions for maternal postpartum depression have various forms and rich contents. Appropriate intervention plans should be made according to the actual situation and the willingness of parturients，and the process of interventions should be well monitored.

Objective To search，evaluate and summarize the best evidence of oral intake management during labor and to provide references for clinical practice. Methods According to the “6S” model of evidence resources，clinical decision support，best practice recommendations，guidelines，evidence summaries，expert consensuses and systematic reviews related to oral intake management published in computer decision support systems，guideline websites，association official websites and databases were searched from the establishment of databases to December 2021. A supplementary search was performed for randomized controlled trials published between January 2018 and December 2021. 2 researchers evaluated the methodological quality of the literature，extracted and summarized evidence according to the subject. Results A total of 12 articles were included，including 1 clinical decision support，5 guidelines，1 evidence summary，3 expert consensuses and 2 randomized controlled trials，and 19 pieces of best evidence were summarized from 4 aspects of health education，dynamic evaluation during labor，recommended schemes of oral intake during labor and systematic support. Conclusion This study summarized the best evidence of oral intake management during labor，which can provide a basis for clinical evidence-based practice. Healthcare professionals should combine the best evidence with clinical situation，expert judgment and maternal wishes to develop personalized oral intake management programs during labor for different groups，so as to ensure energy supply，improve maternal and child delivery outcomes，while improving maternal food satisfaction and relieving emotional stress.
