Objective:To systematically evaluate and integrate the qualitative studies on nurses' experiences with nursing information systems, so as to provide a basis for improving the use and management of nursing information systems.Methods:The qualitative study on nurses' experiences, feelings, and attitudes toward nursing information systems was electronically searched in China National Knowledge Infrastructure, Wanfang Data, VIP, China Biology Medicine disc, PubMed, Web of Science, Cochrane Library, Embase, and PsycINFO. The retrieval period was from database establishment to December 2023. The quality of the literature was evaluated according to the Australia Joanna Briggs Institute Evidence-Based Health Care Centre Quality Assessment Criteria for Qualitative Research (2020). Two researchers independently completed the extraction of data and applied the aggregative synthesis to integrate the results.Results:A total of 10 articles were included. A total of 36 results were extracted, and seven new categories were summarized to form three integrated results, namely, the vertical evolution of technology acceptance attitudes, the "mixed blessing" of information technology, and the future-oriented expectations of users.Conclusions:Managers need to dynamically assess nurses' acceptance of the nursing information system, emphasize nurses' experience of annoyance, reduce their psychological burden, establish a sound feedback mechanism and supportive work environment, and effectively promote the construction of information technology.

To evaluate the optimal administration frequency for interferon-α (IFN-α) and the effect of its combined use with inactive virus on chicken flocks, the prokaryotic expression plasmid pET-22b-ChIFN-α was constructed and transferred into Escherichia coli BL21(DE3) host bacteria to induce the expression of chicken IFN-α and to harvest recombinant proteins inclusion bodies. The expression of recombinant chicken IFN-α was confirmed by SDS-PAGE, and the results demonstrated that the chicken IFN-α (20 kDa) was highly expressed using the prokaryotic expression vector with a concentration of 0.2 mg/mL in the medium. Chicken IFN-α was diluted to 2.5×10⁴ U/fowls and administered to immunized specific-pathogen-free chickens orally in combination with inactivated H9N2 subtype influenza virus. Chicken that received chicken IFN-α were safe after three repeated immunizations (96 h). In addition, chicken IFN-α could induce higher levels of antiviral-related inducible genes in peripheral blood, spleen, and thymus of chicken flocks. The results of a challenge assay revealed that the lowest detoxification rates of chicken IFN-α ranged from three to five days, suggesting a higher capacity to resist H9N2 subtype avian influenza virus. The present study obtained the optimal immune frequency and immunization period for chicken IFN-α to provide theoretical support for the optimal clinical application of IFN-α.

Objective To investigate the distribution and changes of pathogens in intensive care unit of our hospital from 2010 to 2015,and provide treatment suggestions for infection.Methods The data of pathogens and multi-drug resistant organisms(MDROs)in ICU from 2010 to 2015 were analyzed retrospectively by WHONET5.6,Microsoft Office Excel2007 and SPSS19.0.Results The numbers of pathogens in ICU were increasing year by year while the top six were Acinetobacter baumanni,Pseudomonas aeruginosa,Klebsiella pneumoniae,Escherichia coli,Staphylococcus aureus and Candida albicans.The dominant MDROs were multi-drug resistant Acinetobacter baumanni,multi-drug resistant Pseudomonas aeruginosa,extended spectrum β lactamase producing Escherichia coli and Klebsiella pneumonia,methicillin-resistant coagulase negative Staph-ylococcus and methicillin-resistant Staphylococcus aureus,etc.There were statistically dramatic significant differences of most MDROs during the six years(P<0.01).Conclusion The pathogens of ICU were mainly bacteria related to the healthcare associated infection,and the multi-drug resistance was obviously in dynamic change as well as most pathogens.As a suggestion,antibiotic agents should be used rationally according to the antimicrobial susceptibility results for treating the MDROs.
