ABSTRACT
Objective:To systematically evaluate the life experience of patients with postpartum depression.Methods:PubMed, web of science, EMBASE, Scopus, PsychINFO, the Cochrane Library, CNKI, VIP, Wanfang and China biomedical database were searched for qualitative studies on life experience of patients with postpartum depression from the establishment to January 2021. The quality of articles was evaluated by the quality evaluation standard of JBI evidence-based health care center (2016) in Australia, and the results were summarized for meta integration.Results:A total of 23 studies were included, 50 complete results were extracted, 9 new categories were summarized, and 3 integrated results were obtained. Integration result 1: negative psychological emotion experience and coping style; integration result 2: personal role change and social environment influence; integration result 3: needs and obstacles.Conclusions:To improve the public′s cognition of postpartum depression, get the understanding of relatives and the attention of medical staff; pay attention to the life experience of patients with postpartum depression, give all-round support, meet the needs of pregnant women, promote the adaptation of mother′s role, and provide reference for medical staff to give humanized intervention.
ABSTRACT
Objective To establish a GC analytical method for the determination of N-ethyl morpholine in the air of workplace.Methods N-ethyl morpholine in the air of workplace was collected by silica gel tube, desorbed by ethanol, and according to The Criterion of Detection Methods for the Air of Workplace, the linearity range, precision, accuracy and limit of detection were determined by the GC under a certain experimental condition and the experiments of sampling efficiency , the desorption efficiency, penetrating capability and the stability of sample were carried.Results The linear range of N-ethyl morpholine was 0.025-20 mg/ml(r=0.999 8);Relative standard deviations were 3.2%-3.9%;the rates of recovery were 101.00%-102.43%(n=18), the limit of detection was 0.49 ?g/ml, the desorption efficiency was 96.10%-98.73%, the penetrating capability was 14.37 mg(100 g silica gel), and the content of samples were reduced less than 10% percent at the ninth day.Conclusion The method has higher sensitivity, better precision, accuracy, simple sampling, accurate and stable results.It can be used as an effective monitoring method to detect N-ethyl morpholine in the air of workplace.
