Implementation Science is an interdisciplinary field dedicated to systematically studying how to effectively translate evidence-based research findings into practical application and implementation. In the health-related context, it focuses on enhancing the efficiency and quality of healthcare services, thereby facilitating the transition from scientific evidence to real-world practice. This article elaborates on Theories, Models, and Frameworks (TMF) within health-related Implementation Science, clarifying their basic concepts and classifications, and discussing their roles in guiding implementation processes. Furthermore, it reviews and prospects current research from three aspects: the constituent elements of TMF, their practical applications, and future directions. Five representative frameworks are emphasized, including the Consolidated Framework for Implementation Research (CFIR), the Practical Robust Implementation and Sustainability Model (PRISM), the Exploration, Preparation, Implementation, Sustainment (EPIS)framework, the Behavior Change Wheel (BCW), and the Normalization Process Theory (NPT). Additionally, resources such as the Dissemination & Implementation Models Webtool and the T-CaST tool are introduced to assist researchers in selecting appropriate TMFs based on project-specific needs.

Objective:To explore the characteristics of delay discounting and non-systematic response data in intertemporal choice of adults with attention deficit hyperactivity disorder(ADHD),and to explore the best data processing strategy for delay discounting task.Methods:Totally 108 adults with ADHD meeting the diagnostic cri-teria of the Diagnostic and Statistical Manual of Mental Health Disorder,Fifth Edition(DSM-5)and 87 gender matched normal controls were enrolled.ADHD symptoms were assessed using the ADHD Symptom Rating Scale,the delay discounting task was used to measure the delay discounting rate,and a model-free algorithm was used to i-dentify non-systematic response data.Results:There was no significant difference in the proportion of non-systemat-ic response data between ADHD group and normal control group(P＞0.05).In the data sets using different data screening strategies,the delay discounting rates were higher in the ADHD group than in the normal control group(Ps＜0.05).The delay discounting rates were positively correlated with the hyperactive impulse scores(r=0.24,P=0.001),the inattention scores(r=0.20,P＜0.01)and the total scores of ADHD symptom Rating Scale(r=0.22,P＜0.01).Conclusion:Adults with ADHD prefer to obtain immediate small rewards in intertemporal choice.The immediate preference of intertemporal choice may be mainly related to hyperactive impulsive symp-toms.Exclusion strategy of non-systematic response data may be more applicable to delay discount task research.

Objective A HPLC-quantitative analysis of multi-components by single marker(QAMS)was established to determine 5 ingredients including uracil,uridine,hypoxanthine,inosine and guanosine in Periplaneta americana.Methods Separation took place on a Agilent ZORBAX SB-Aq column(250 mm×4.6 mm,5 μm)by gradient elution of methanol-0.01 mol·L-1 potassium dihydrogen phosphate at 20℃with a flow rate of 1.0 mL·min-1.The detection wavelength was 260 nm and the injection amount was 10 μL.The relative correction factors(fa/b)was calculated for the other four components with uridine as an internal standard.The content of 5 ingredients in 10 batches of Periplaneta americana was determined by QAMS.Results were compared with those of external standard method(ESM).Results Five nucleosides showed good linear relationships in their own ranges(r＞0.999 5),and the average recoveries ranged from 97.0%to 100.8%.The relative correction factors of uracil,hypoxanthine,inosine and guanosine were 0.908 0,1.005 3,1.969 5 and 1.303 4,respectively.Conclusion The established method is accurate and stable.It can provide theoretical reference for the quality control of Periplaneta americana.

Objective:To summarize the relevant evidence of exercise intervention for patients with multiple myeloma at home and abroad, and provide evidence-based basis for medical staff to formulate exercise intervention programs.Methods:Through the method of evidence-based nursing, the literatures related to exercise intervention for patients with multiple myeloma were systematically retrieved from relevant guideline websites, professional association websites and databases at home and abroad, including best practices, recommended practices, guidelines, expert consensus, evidence summary, systematic reviews and so on. The search time limit was established until April 16, 2024. Two researchers evaluated the quality of the literature and extracted the data. JBI pre-classification of evidence and level of Recommendation system (2014 version) was used to determine the level of evidence items and recommendation level.Results:A total of 15 articles were included, including 1 clinical decision, 4 guidelines, 8 systematic reviews, 1 expert consensus and 1 evidence summary. A total of 26 pieces of evidence were summarized, including 5 aspects, including applicable population, exercise evaluation, exercise plan, exercise precautions and exercise management.Conclusions:The best evidence summarized in this study provides a basis for the development and management of exercise intervention in patients with multiple myeloma. It is suggested that clinical staff should fully consider the clinical context when applying the evidence, and develop personalized exercise intervention programs based on the patient′s status and preferences.

Objective:To improve the early graded rehabilitation nursing model suitable for postoperative children with congenital heart disease, providing reference for related research and clinical practice.Methods:Searched databases like JBI, PubMed, Medline, CINAHL, CNKI, Wanfang Data and related websites for information on postoperative rehabilitation of children with congenital heart disease. We improved the first draft model with qualitative interview results and used Delphi method to conduct two rounds of consultation for 16 experts from 6 provinces and cities to further test the scientific and feasibility of the model.Results:The early graded rehabilitation nursing model for postoperative children with congenital heart disease includes 4 first-level items, 15 second-level items and 48 third-level items. The 4 first-level items are the evaluation of the early graded rehabilitation nursing model, the grading standard of the early graded rehabilitation nursing model, the implementation of the early graded rehabilitation nursing model, the effect evaluation and health education. Experts′ response rates were 100% in the 2 rounds, experts′ authority coefficient were 0.82 and 0.84 respectively, and the Kendall′ s W rank-order correlation coefficients of all levels of indicators were 0.188-0.246, 0.223-0.287 (all P<0.01). Conclusions:The improved early graded rehabilitation nursing model for postoperative children with congenital heart disease is scientific, pertinence and safe, which can provide guidance for clinical rehabilitation nursing practice.

Objective:To further explore the symptom experience and coping strategies of patients with multiple myeloma, so as to provide reference for the formulation of symptom management programs.Methods:Objective sampling method was used to conduct semi-structured in-depth interviews on 15 patients with multiple myeloma in Hematology Department of Nanjing Drum Tower Hospital from December 2021 to June 2022 and the model of symptom management theory was used as the framework to construct an interview outline. The Colaizzi 7-step analysis method was used to analyze data and extract themes.Results:Three main themes were summarized: symptom experience (obvious symptom perception, poor symptom assessment ability, negative symptom response); symptom management strategy (vague knowledge of symptom management, hope to get professional guidance, expect to get continuity of management); symptom management outcomes (recurrent anxiety, reordering, adaptive behavior).Conclusions:Patients with multiple myeloma have diverse and complex real symptom experience in different periods. Medical staff should pay attention to patients′ symptom response and coping needs and develop a systematic symptom management plan, so as to help them create better self-management and improve their quality of life.

Ferroptosis, as a newly discovered cell death form, has become an attractive target for precision cancer therapy. Several ferroptosis therapy strategies based on nanotechnology have been reported by either increasing intracellular iron levels or by inhibition of glutathione (GSH)-dependent lipid hydroperoxidase glutathione peroxidase 4 (GPX4). However, the strategy by simultaneous iron delivery and GPX4 inhibition has rarely been reported. Herein, novel tumor microenvironments (TME)-activated metal-organic frameworks involving Fe & Cu ions bridged by disulfide bonds with PEGylation (FCSP MOFs) were developed, which would be degraded specifically under the redox TME, simultaneously achieving GSH-depletion induced GPX4 inactivation and releasing Fe ions to produce ROS

Objective:To evaluate the effect of adductor canal block(ACB)and local infiltration anesthesia(LIA)around the knee joint on inflammatory responses in the patients undergoing total knee arthroplasty(TKA).Methods:Sixty American Society of Anesthesiologists physical status Ⅱor Ⅲ patients of both sexes, aged 54-76 yr, scheduled for elective TKA, were divided into 2 groups ( n=30 each) using a random number table method: ACB group (group A) and ACB combined with LIA around knee joint group (group AL). ACB was performed with 0.5% ropivacaine 15 ml after endotracheal intubation in group A and group AL, and in addition LIA was performed around the knee joint after the osteotomy was completed during surgery in group AL.The patient-controlled ACB analgesia was applied at the end of surgery in both groups.The analgesic solution contained ropivacaine 400 ml (in 0.9% normal saline 200 ml), and the analgesic pump was set up to deliver a 5 ml bolus dose with a 30-min lockout interval and background infusion at 5 ml/h.When visual analog scale score>4, and pain was still not relived at 30 min after pressing by patients, pethidine hydrochloride 100 mg was intramuscularly injected as rescue analgesic.Peripheral venous blood samples were collected immediately before surgery (T 0) and at 24, 48 and 72 h after surgery (T 1-3) for determination of serum interleukin-6 (IL-6) and IL-10 concentrations by enzyme-linked immunosorbent assay.The muscle strength on the affected side was assessed at T 1-3.The patients′ satisfaction score, requirement for rescue analgesia, and adverse effects were recorded. Results:Compare with group A, the serum IL-6 concentrations were significantly decreased and serum IL-10 concentrations were increased at each time point after surgery, postoperative patients′ satisfaction scores were increased, the requirement for rescue analgesia was decreased ( P<0.05), and no significant change was found in the quadriceps strength of the affected limb and incidence of adverse reactions after surgery in group AL ( P>0.05). Conclusion:ACB and LIA around the knee joint can mitigate postoperative inflammatory responses in the patients undergoing TKA.

OBJECTIVETo observe the effect difference between fire needle combined with chemotherapy and fire needle on quality of life in patients with chemotherapy of non-small cell lung cancer (NSCLC).

METHODSWith randomized controlled method, a total of 60 patients with chemotherapy of NSCLC were divided into an observation group (fire-needle plus chemotherapy group) and a control group (chemotherapy group), 30 cases in each one. The observation group was treated with fire needle atpoints which consisted of Geshu (BL 17) and Danshu (BL 19), combined with chemotherapy selected from TP (paclitaxel+cisplatin)/GP (gemcitabine+cisplatin)/DP (docetaxel+cisplatin)/NP (vinorelbine+cisplatin) by the oncologist according to patients' condition. The fire needle was given once a day for 7 days, and chemotherapy was given for 21 days. The control group was treated with chemotherapy alone for 21 days. Before and after treatment, response evaluation criteria in solid tumors (RECIST) was applied for evaluation, and Karnofsky performance status (KPS) and functional assessment of cancer therapy-lung (FACT-L) were applied for evaluation of quality of life in patients with chemotherapy of NSCLC.

RESULTSThe effective rate was 20.0% (6/30) and the stability rate was 73.3% (22/30) in the observation group, which were insignificantly higher than 16.7% (5/30) and 63.3% (19/30) in the control group, respectively (both>0.05). The KPS after treatment was lower than that before treatment in the control group (<0.05); the KPS after treatment was similar to that before treatment in the observation group (>0.05); the KPS in the observation group after treatment was higher than that in the control group (<0.05). The total score and each item score of FACT-L after treatment were higher than those before treatment in the observation group (all<0.05); the physical score and emotional score of FACT-L after treatment were higher than those before treatment in the control group (both<0.05); the total score, physical score, functional score and subscale score in the observation group were significantly higher than those in the control group after treatment (all<0.05), while the social/family score and emotional score in the observation group were insignificantly higher than those in the control group (both>0.05). The differences of KPS total score before and after treatment in the two groups had moderate positive correlation with differences of FACT-L total score (<0.01).

CONCLUSIONFire needle can improve quality of life in patients of NSCLC chemotherapy.
