Objective:To select the relevant evidence of percutaneous pericardial drainage tube nursing and summarize the best evidence.Methods:Evidence-based questions were established based on PIPOST model. BMJ Best Clinical Practice, China Biology Medicine disc (CBM) , UpTodate, Cochrane Library, Joanna Briggs Institute Evidence-based Health Care Database, China Guide Network, British Guide Network, National Guide Line Clearing House (NGC) , PubMed, EMbase, Evidence-based Medicine (EBM) , Registered Nurses' Association of Ontario (RNAO) , The European Society of Cardiology (ESC) , American Heart Association (AHA) , Chinese Journal Full-text Database and Wanfang Database were conducted computer retrieval. The search time was from the establishment of the database to December 31, 2020. Two researchers respectively evaluated the quality of the included literature and extracted data and summarized and summarized the evidence that met the standards.Results:Finally, 12 articles were included, including 1 evidence summary, 2 systematic reviews, 1 systematic assesment, 2 guidelines, 1 expert consensus and 5 case series studies. Finally, 11 pieces of evidence were formed, including 6 themes such as drainage tube selection, puncture wound nursing, drainage flow control, flushing and sealing of the tube, observation and recording points, extubation indications and care.Conclusions:This study summarizes the best evidence for percutaneous pericardial drainage tube nursing, which provides evidence-based basis for improving the quality of percutaneous pericardial drainage tube care.

The aim of this study was to prepare a self-assembled nanoparticle monkeypox vaccine candidate and study its immune response characteristics,so as to provide reference test data for its vaccine design.The antigen protein A29L-SpyTag and the backbone protein Mi3-SpyCatcher were expressed and purified by prokaryotic system,and nanoparticles A29L-Mi3 were prepared by chemical assembly,then the antibody titers were determined by ELISA,the antibody neutralization was determined by plaque test,and the cytokine secretion of lymphocytes was determined by flow cytometry to describe the immune response characteristics.Data showed that A29L-Mi3 nanoparticles were successfully prepared,and the particles were uniformly distributed in hollow cages,with an average particle size of(29±0.19)nm.After the A29L-Mi3 nanoparticle vaccine candidate was combined with SP01 adjuvant,the neutralizing antibody titer was stronger than that of the A29L protein candidate,and the A29L-Mi3 nanoparticle vaccine candidate could obtain neutralizing antibodies with similar titers after two immunizations.The level of mouse T lymphocyte immune response activated by the A29L-Mi3 nanoparticle vaccine candidate was higher than that of the A29L protein vaccine candidate.In conclusion,A29L-Mi3 protein nanoparticles with uniform structure have successfully assembled in vitro,which has strong immunogenicity and improved neutralization ability after combination with SP01 adjuvant,thus provided reference data for the optimization of immune programs.In addition,the level of cellular immune response is higher than that of A29L protein alone,which provides a reference for the design and development of monkeypox vaccine.
