ABSTRACT
Objective:To summarize the best evidence of thirst management in ICU patients and provide evidence-based basis for dinical practice.Method:According to the "6S" evidence pyramid model, the literature on thirst management of ICU patients was systematically retrieved from relevant guidelines websites, evidence-based databases, association websites and original literature databases at home and abroad. The retrieval time was from the establishment of the database to June 31, 2022. Two researchers with evidence-based nursing training independently completed literature quality evaluation. To extract and summarize the evidence of the literature that meets the quality standard.Results:A total of 17 articles were included, including 8 randomized controlled trials, 5 quasi-experimental studies and 4 cross-sectional studies. The 18 pieces of best evidence were formed, including 5 aspects: basic requirements of thirst management, intervention evaluation, intervention methods, matters needing attention and health education.Conclusions:This study summarized the best evidence of thirst management in ICU patients. Nurses should translate and apply the best evidence in combination with the clinical situation and specific policies of the department to relieve the thirst symptoms of ICU patients.
ABSTRACT
Genome editing is a novel targeted genome modification biotechnology, which could successfully mutate specific loci as well as generate gene replacement and insertion in various organisms. So far, genome editing technology has been widely applied in investigating gene function and developing valuable traits in both model plants and major crops. In this review, we briefly survey the historical development of genome editing technology, summarize recent progress using the CRISPR/Cas9 system for plant genome editing and explore the potential of the CRISPR/Cas technology in improving forage legumes.
ABSTRACT
Congenital heart disease(CHD) is one of the most common birth defects,which is caused by either hereditary or environmental factors,and more commonly by the combination of both.Although CHD is known to be a polygenetic disease,its molecular pathogenesis is still poorly understood.Many genes including the transcription factors have recently been identified to be involved in the development of heart as well as in the pathogenesis of CHD.At the molecular level,this paper reviews the roles of the transcription factors of GATA4/5/6,Nkx2.5,Nkx2.7,TBX1,TBX5,and TBX20,and the interactions among them in the abnormal development of the heart.
