Evidence-based public health, as the forefront of modern public health practice, has increasingly important in public health field. However, a significant gap remains between the available evidence and its practical application. Effectively disseminating and implementing evidence-based public health practice in real-world settings has become a key challenge in contemporary public health research. In this context, Implementation Science has emerged as a vital discipline. This paper explores the critical role of Implementation Science in public health, reviews the origins and core components of the Consolidated Framework for Implementation Research (CFIR), and analyzes the current application of CFIR in public health through bibliometric methods. Additionally, it discusses specific examples to further elucidate the steps involved in using the CFIR and its application contexts. The findings indicate that since 2015, research on CFIR in public health has progressively increased, showing a continuous upward trend. CFIR applications mainly address context-specific facilitators, health decision-making, barrier and facilitator identification, and community-based participatory evaluation, predominantly employing qualitative and mixed-methods research. This paper not only reviews and analyzes the current use of CFIR in public health but also provides a detailed discussion on its application. The goal is to offer valuable insights for the development of Implementation Science research within China's public health sector.

Objective:To investigate the function of miR-5581-5p and its interaction with tripartite motif 22 (TRIM22) during the terminal differentiation of human acute promyelocytic leukemia (APL) cells into granulocytes.Methods:APL cells (NB4) were differentiated into granulocytes by all-trans retinoic acid (ATRA), using dimethylsulfoxide (DMSO) as the control. The expression of TRIM22 was detected by real-time fluorescent quantitative PCR (qRT-PCR) and Western blotting, and the expression of miR-5581-5p was detected by qRT-PCR during cell differentiation. miRNA expression was regulated by cell transfection with miR-5581-5p mimic and inhibitor, and negative control was set, and qRT-PCR was used to verify the regulatory effect. Luciferase binding assay was performed to detect the presence of targeted binding. Western blotting was used to detect the expression of TRIM22 after miRNA differential expression. Flow cytometry was used to detect the effects of the regulation of miR-5581-5p on the differentiation of NB4 cells induced by ATRA.Results:After ATRA induced NB4 cells to differentiate into granulocytes, the gene expression level of TRIM22 was significantly higher than that of the control group (24.56±2.80 vs. 1.02±0.13; t=8.392, P=0.001). The level of protein expression was also significantly higher than that of the control group (0.80±0.01 vs. 0.17±0.01; t=44.900, P<0.001). The expression level of miR-5581-5p in NB4 cells differentiation group was significantly lower than that in the control group (0.14±0.02 vs. 1.01±0.08; t=10.840, P<0.001). The results of the dual luciferase reporter gene showed that the luciferase activity of the co-transfected miR-5581-5p mimic and TRIM22 WT group was significantly lower than that of the co-transfected miR-5581-5p mimic and TRIM22 MUT group (0.73±0.02 vs. 0.98±0.03; t=7.534, P=0.002). Western blotting showed that after transfection with miR-5581-5p inhibitor, the expression of TRIM22 was significantly higher than that of the negative control (0.44±0.01 vs. 0.21±0.01; t=18.290, P<0.001). While after transfection with miR-5581-5p mimic, the expression of TRIM22 decreased significantly compared with the negative control (0.62±0.01 vs. 0.80±0.02; t=6.402, P=0.003). CD11b expression of miR-5581-5p mimic group after ATRA treatment was significantly lower than that of the control group (45.80±1.80 vs. 56.61±1.88; t=4.159, P=0.014). The expression of CD11b in miR-5581-5p inhibitor group was significantly higher than that in the control group (66.48±2.54 vs. 52.60±1.70; t=4.539, P=0.011). Conclusion:miRNA-5581-5p can bind to TRIM22 3′UTR and negatively regulate TRIM22 expression. The decrease of miR-5581-5p can increase the expression of TRIM22, then promote the differentiation of ATRA-induced NB4 cells into granulocytes.
