Objective:To systematically evaluate the qualitative research on experience of fear of falling in the elderly, so as to provide theoretical basis for nursing practice.Methods:Qualitative researches on the fear of falling among the elderly were systematically searched in PubMed, Web of Science, Embase, Cochrane Library, China National Knowledge Infrastructure, WanFang Data, VIP, and China Biology Medicine disc. The search period was from database establishment to November 5, 2023. The quality of literature was evaluated using the quality evaluation criteria for qualitative research of the Australia Joanna Briggs Institute Evidence-Based Health Care Center, and the results were integrated using the Meta-synthesis.Results:A total of 13 articles were included, 44 themes were extracted, categorized into 12 categories, and refined into four integrated results, namely perception of fear of falling, influencing factors of fear of falling, coping strategies in attitude and behavior, and multidimensional needs for rehabilitation nursing.Conclusions:Medical and nursing staff should pay attention to and understand the fear of falling among the elderly, evaluate their fear of falling from multiple dimensions and dynamically, provide personalized guidance based on coping behaviors, create support systems to alleviate their fear of falling and meet their multidimensional needs, so as to improve their quality of life.

Objective To investigate the effects of vaspin on insulin resistants of 3T3-L1 adipocyte through the insulin receptor substrates (IRS) /phosphatidylinositol 3-kinase (PI3K) /protein kinase B (Akt) /glucose transporter (Glut) signaling pathway.Methods 3T3-L1 cells cultured by palmitic acid (PA) were used to establish insulin resistance models,which were divided into PA group,PA + 100 ng/ml vaspin group,PA+200 ng/ml vaspin group,PA+400 ng/ml vaspin group and PA+400 ng/ml vaspin+wortmannin (PI3K inhibitor) group.Glucose uptake and consumption were assessed by 2-deoxy H3-D-glucose incorporation and glucose oxidase-peroxidase respectively.IRS/PI3K/Akt/Glut signaling pathway was evaluated using reverse transcription polymerase chain reaction and Western blot analysis.Results Compared with PA group,glucose uptake and consumption increased gradually with the increasing of vaspin concentration in other groups (P ＜ 0.05).mRNA levels of IRS-1,Akt and Glut 4 increased gradually as vaspin concentration increasing (P＜0.05),and the ratios of p-IRS-1 to IRS-1,p-Akt to Akt and Glut 4 protein level also showed the same trends (P＜0.05).However,glucose uptake and consumption in PA+400 ng/ml vaspin+wortmannin group were less than that of PA +400 ng/ml vaspin group (P＜0.05).PA+400 ng/ml vaspin+wortmannin group showed lower mRNA and protein phosphorylation levels of IRS-1,Akt and Glut 4 (P＜0.05),and that the ratios of p-IRS-1 to IRS-1,p-Akt to Akt and Glut 4 protein levels decreased (P＜0.05).Conclusions Vaspin can improve the insulin sensitivity of 3T3-L1 adipocyte by activating IRS/PI3K/Akt/Glut signaling pathway.
