Implementation science aims to facilitate the efficient dissemination and sustainable application of evidence based interventions, and has accordingly generated a variety of theories, models, and frameworks. Among these, the Exploration, Preparation, Implementation, and Sustainment (EPIS) frameworkfunctions both as a process model and a determinant framework, emphasizing the staged and iterative nature of implementation, and systematically explaining the influence of multilevel factors on implementation processes and outcomes through four dimensions: outer context, inner context, bridging factors, and innovation factors. The EPIS framework has been widely applied in health and public service settings internationally, yet its use in China based research remains relatively limited. This article systematically introduces the core components and application methods of the EPIS framework, and illustrates its value in identifying key influencing factors, developing implementation strategies, and optimizing implementation outcomes through case examples from the health sector, aiming to provide a methodological reference for implementation research and the promotion of evidence based interventions in China.

Objective To investigate the therapeutic effects and mechanisms of cinnamaldehyde(CA)on hepatic fibrosis in non-alcoholic fatty liver disease(NAFLD)rats.Methods A NAFLD rat model was established using a high-fat diet.Successfully modeled rats were randomly divided into:model group,low-and high-dose CA groups,and high-dose CA+K6PC-5[a sphingosine kinase-1(SphK1)activator]group,with healthy rats as normal controls.After intervention,serum lipid profiles[total cholesterol(TC),triglycerides(TG),low-density lipoprotein cholesterol(LDL-C),high-density lipoprotein cholesterol(HDL-C)]and liver function markers[alanine aminotransferase(ALT),aspartate aminotransferase(AST)]were measured using an automated biochemical analyzer.Serum inflammatory cytokines(TNF-α,IL-6,IFN-γ)were quantified by ELISA.Hepatic histopathology was evaluated via hematoxylin-eosin(HE)and Masson staining.Immunohistochemistry detected fibrosis-related proteins(COL1A1,α-SMA),while Western Blot analyzed SphK1 and sphingosine-1-phosphate(S1P)expression.Results Compared with the normal group,the model group showed significant destruction of hepatic lobule structure,hepatocyte swelling and degeneration,disordered cell arrangement,abundant lipid vacuoles in cytoplasm,obvious inflammatory cell infiltration,extensive blue collagen fiber deposition,and severe fibrosis.Moreover,the levels of TC,TG,LDL-C,ALT,AST,TNF-α,IL-6,IFN-γ,COL1A1,α-SMA,SphK1,and S1P were significantly increased,while HDL-C levels were decreased,with statistically significance(P＜0.05).Compared with the model group,both low-and high-dose CA groups demonstrated alleviated liver histopathological changes,reduced blue collagen fiber deposition,and improved fibrosis.These groups also showed significantly decreased levels of TC,TG,LDL-C,ALT,AST,TNF-α,IL-6,IFN-γ,COL1A1,α-SMA,SphK1,and S1P,along with increased HDL-C levels(P＜0.05).However,compared with the high-dose CA group,the high-dose CA+K6PC-5 group exhibited more severe destruction of hepatic lobule structure,aggravated hepatocyte swelling and degeneration,dramatically increased cytoplasmic lipid vacuoles,significant inflammatory cell infiltration,increased blue collagen fiber deposition,and worsened fibrosis.This group also had significantly elevated levels of TC,TG,LDL-C,ALT,AST,TNF-α,IL-6,IFN-γ,COL1A1,α-SMA,SphK1,and S1P,along with reduced HDL-C levels(P＜0.05).Conclusion CA alleviates hepatic fibrosis in NAFLD rats by inhibiting the SphK1/S1P signaling pathway.

Adolescent idiopathic scoliosis(AIS)is a complex three-dimensional deformity involving coronal,sagittal,and axial planes,with a prevalence that should not be overlooked.With advancements in technology and in-depth research,an increasing number of hospitals and physicians are exploring standardized diagnostic and treatment approaches for AIS.Comprehensive and in-depth understanding is required for AIS,including its etiology,screening and diagnosis,classification,assessment and examination,treatment options,exploration of current focus,and evaluation of quality of life.Such understanding ensures that the diagnostic and treatment are scientific,standardized,and timely.Based on the principles of evidence-based medicine,a consensus on the diagnosis and treatment of AIS is reached after multiple discussions among spinal surgery experts,aiming to provide reference and guidance for clinical practice.

Objective To explore the differences in therapeutic efficacy and possible mechanism of different routes of administration of fullerene nanoparticles in the treatment of radiation retinopathy.Methods Eight-week-old adult male SD rats were randomly divided into blank group(Control),irradiation group(X-Ray),irradiation+vitreous cavity administration group[X+F(IVT)],irradiation+ocular surface administration group[X+F(OS)],and irradiation+intravenous administration group[X+F(IV)],with 5 rats in each group.The blank group was not treated,the irradiation groups exposed to X-ray irradiation to establish the model,and fullerenol nanoparticles were given to the treatment groups through different routes after irradiation.At 7,14,and 28 d after modeling,body weight and fundus changes were measured to evaluate drug safety,retinal optical coherence tomography(OCT)was used to observe the change in retinal tissue structure,and electroretinography(ERG)was applied for oscillatory potentials(OPs)to evaluate visual function.CD31 immunofluorescence staining was carried out to evaluate retinal endothelial vascular status,and in vivo imaging was utilized to evaluate the accumulation of fullerenol nanoparticles in the eyes.Results The growth curves of body weight demonstrated that fullerenol nanoparticles did not affect the growth and development of rats,with no statistical difference between the treatment groups and the control group.Irradiation resulted in a significant reduction in visual function,decreased amplitudes of a-wave and b-wave,and declined OPs(P<0.01),and significantly increased thicknesses of the ganglion cell layer(GCL)and the inner nuclear layer(INL)in the retinas,as evidenced by OCT(P<0.01),along with a notably absent presence of CD31-positive cells(P<0.01).Notably,the X+F(IVT)group obtained significantly improved visual function after intravitreal administration,effectively maintained thickness of the GCL and INL,and prevention against the loss of CD31-positive cells(P<0.01).However,no such effective results were observed in the irradiated groups receiving intravenous either ocular surface administration.In vivo imaging revealed that intravitreal administration maintained high ocular accumulation of fullerene for 96 h,while ocular surface administration sustained these concentrations for only 12 h.Intravenous administration,in contrast,only led to a predominant drug distribution in vascular-rich areas,but reduced ocular accumulation.Conclusion Fullerene nanoparticles possess a therapeutic effect on radiation retinopathy,and the intravitreal administration route demonstrates better efficacy than ocular surface and intravenous administration.

Objective:To explore the application value of the combination of failure mode and effects analysis (FMEA) and work breakdown structure (WBS) on management of telemetry monitoring system. Methods:Seven sets of used telemetry monitoring systems in Huzhou Third People's Hospital from March 2022 to April 2024 were selected. The routine mode was used to manage the telemetry monitoring systems from March 2022 to February 2023,and the management mode of telemetry monitoring systems based on FMEA and WBS was adopted to manage the telemetry monitoring systems from May 2023 to April 2024. FMEA method was used to analyze the quantitative risk scores of various failures in 1740 uses of the telemetry monitoring system from March 2022 to February 2023,and the fault type was represented by Fx. According to the risk quantification score,the top 5 failure types included poor radio frequency (RF) signal (F2),larger pseudo-interference (F3) of electrocardiogram (ECG),abnormal measurement of blood oxygen saturation (SpO2) (F6),excessive movement and mistake touch (F8) of patients,and identification (ID) number error (F9) of telemetry emission box. WBS quality management method combined with tree chart,countermeasure fishbone chart,task assignment matrix and other tools were performed to conduct the setting of expected objectives,countermeasure analysis,task formulation and work implementation of management of telemetry monitoring system. The above indicators were compared with the changes of the top 5 failure risk grading and incidence of failure in 1850 uses of management of telemetry monitoring system from May 2023 to April 2024. Results:After the telemetry monitoring system was used to conduct management,the risk grading of the F2,F3,F6,F8 and F9 failures with highest risk grading reduced respectively to low grade,middle grade,middle grade,low grade and middle grade. At the same time,the number of F2,F3,F6,F8,F9 failures with the highest risk grading and total failures were respectively 91,89,39,45,39 and 478 times,and the incidence rates of them were 4.92％,4.81％,2.11％,2.43％,2.11％ and 25.84％,which were significantly lower than those of adopting conventional management methods. The differences of them between two methods were statistically significant (x2=2.125,6.911,9.099,2.261,2.431,32.491,P<0.05). Conclusion:The management of combined quality management method of FMEA and WBS for telemetry monitoring system can reduce risk grading and incidence rate of equipment failure,and ensure the safety of equipment in clinical use.

Purpose To explore the expression level of let-7b-5p in glioma and its effects and potential mecha-nisms on U251 cell growth.Methods The expression of let-7b-5p in glioma was detected using qRT-PCR.Data from the CGGA database were analyzed to examine the relationship between the let-7b-5p expression levels,WHO grade and overall survival rates of glioma patients.Transient transfection was used to downregulate the expression of let-7b-5p and IGF1R in U251 cells.The role and potential mechanism of let-7b-5p in the U251 cell were evaluated using qRT-PCR,CCK8 assays,clone formation assays,Western blotting,and double luciferase reporter assays.Results The expres-sion of let-7b-5p in glioma cells(A172:3.64±0.64,V251:4.56±0.52,U87-MG:3.31±0.50)and tissues(2.18±0.22)was significantly higher than that in astrocytes(HMC3:1.00±0.21,P＜0.05 or P＜0.01)and nor-mal brain tissues(1.01±0.19,P＜0.05).Let-7b-5p expression was negatively correlated with WHO grades but pos-itively correlated with survival rates in primary and recurrent glioma patients(P＜0.000 1 and P=0.028,respective-ly).Knockdown of let-7b-5p in U251 cells significantly promoted the growth of glioma cells(CCK8:knockdown group 126.00±12.09 vs miR-NC group 90.93±5.13,P＜0.05)and activated PI3K/AKT signal pathway.Suppressing IGF1R expression in U251 cells reversed the effects of let-7b-5p knockdown on glioma cell growth[CCK8:let-7b-5p knockdown+IGF1R knockdown group(92.08±6.14)vs let-7b-5p knockdown+sh-NC group(116.67.08±8.50)]and PI3K/AKT signal pathway activation.Conclusion Let-7b-5p functions as a tumor suppressor gene in glioma.It may regulate glioma cell growth by targeting IGF1R and modulating PI3K/AKT signal pathway.

Reporting guidelines are structured checklists for researchers to follow when reporting spe-cific types of studies.As researches conducted in real-world settings to address practical issues,implementa-tion research has stringent requirements for the replicability of result and the transparency of reporting,making its reporting guidelines particularly important.This paper systematically introduces the reporting guidelines in the field of implementation science,outlines their classification systems and scopes of applica-tion,and focuses on explaining the core characteristics and functions of five key reporting guidelines,inclu-ding the Standards for Reporting Implementation Studies(StaRI),Reporting guidelines for implementation and operational research,the Template for Intervention Description and Replication(TIDieR),the Frame-work for Reporting Adaptations and Modifications-Enhanced(FRAME),and recommendations for specifying and reporting implementation strategies.Furthermore,combined with the PEDALs research paradigm in im-plementation science,this paper further clarifies the specific application pathways for reporting guidelines and discusses directions for refinement,aiming to provide references for researchers to select appropriate reporting guidelines.
