The Proctor's reporting guideline for implementation strategies represents a landmark framework in the field of implementation science, aiming to address the issue of inconsistent reporting in implementation research by standardizing the naming, definition, and operationalization of implementation strategies, thereby enhancing the credibility and utility of research findings. This paper provides an in-depth interpretation of the core connotations of this reporting guideline and illustrates its application in developing interview outlines and specifying implementation strategies, using a brief smoking cessation intervention project as a case study. Through this reporting guideline, abstract recommendations for implementation are systematically transformed into clear, multidimensional operational guides, significantly improving the transparency of strategy connotations and the replicability of actual execution. Meanwhile, the case study highlights the flexibility of the guideline, which allows researchers to adapt the content and format of strategies based on local resources and cultural contexts, thus enhancing practical adaptability while maintaining scientific rigor. However, the application of Proctor's reporting guideline still faces challenges, primarily manifested in the potential confusion surrounding the constructs of temporality and dose in practice, as well as the challenges that the inherent flexibility of the guideline may pose to the assessment of fidelity and effectiveness. Despite these limitations, the reporting guideline remains a vital tool for implementation research; future efforts should focus on optimizing its application—through refining operational guidelines, standardizing flexible adaptations, and involving stakeholders—to better guide implementation studies and continuously promote high-quality development in the field.

With the accelerating trend of population aging, the number of elderly patients with lung cancer continues to rise, and the disease burden is becoming increasingly heavy. The clinical management of these patients faces severe challenges due to their decreased physiological reserve, complex comorbidities, and significant individual heterogeneity. Consequently, under traditional diagnosis and treatment models, doctors often struggle to identify the individualized risks of elderly patients in a timely and comprehensive manner, which can easily lead to decision biases such as undertreatment or overtreatment. In view of this, this study advocates for the establishment of an umbrella decision-making model specifically tailored for elderly lung cancer patients. Grounded in a multidisciplinary team (MDT) platform, this model deeply integrates oncological indicators with the comprehensive geriatric assessment (CGA) system. By holistically considering multidimensional variables including tumor burden, organ function, frailty index, cognitive status, and social support, the model establishes an operational mechanism characterized by "single entry, precise stratification, and targeted selection". Accordingly, patients can be scientifically triaged into distinct intervention tiers, such as active surveillance, minimally invasive surgery, drug therapy, radiotherapy, and best supportive care, thereby achieving real-time alignment between treatment intensity and patient fitness. This article elaborates on the construction logic and key operational procedures of this novel decision-making framework, aiming to guide clinical practice beyond the limitations of a tumor-centric perspective toward a holistic, dynamic, whole-course management strategy. This transition seeks to ensure optimal quality of life and clinical net benefit for elderly patients alongside survival prolongation.

ObjectiveTo investigate the inhibitory effect of gingerol, an active component of ginger, on Staphylococcus aureus (S. aureus) infection, and to preliminarily explore its mechanism related to extracellular vesicles (EVs). MethodsS.aureus infection models were established in human umbilical vein endothelial cell (HUVECs), Vero E6 cells, and C57BL/6 mice. Experimental groups included control, infection, and gingerol-treated groups. Bacterial load and VE-cadherin protein expression were detected using immunofluorescence and Western blot. EVs were isolated by size exclusion chromatography and characterized by transmission electron microscopy and nanoparticle tracking analysis. miRNA sequencing was performed on EVs. ResultsGingerol treatment significantly reduced the bacterial load in both in vitro and in vivo infection models and upregulated VE-cadherin expression. miRNA sequencing of EVs revealed that S. aureus infection upregulated the expression of hsa-miR-320c, while gingerol treatment reversed this abnormal expression. Bioinformatic analysis further predicted that the target genes of hsa-miR-320c were significantly enriched in cell junction-related pathways. ConclusionGingerol exhibits clear antibacterial and host-protective effects, by regulating hsa-miR-320c in EVs to maintain endothelial barrier integrity.

Objective:
To systematically evaluate the relationship of exposure to five heavy metals, namely lead, arsenic, cadmium, mercury and aluminum with obesity in children and adolescents, so as to provide a scientific basis for subsequent research in the area.
Methods:
Four Chinese databasesc (CBM, VIP, CNKI and Wanfang) and four foreign databases (OVID, PubMed, Web of Science and EBSCO), were searched to collect relevant studies, and the search period was from the establishment of the database to May 5, 2024. After 2 investigators independently screened the literature, extracted the data and evaluated the risk of bias of the included studies, the results were analyzed quantitatively and summarized qualitatively.
Results:
A total of 5 cohort studies on lead exposure and 17 cross sectional studies involving exposure to lead ( n =13), cadmium ( n =8), mercury ( n =8), arsenic ( n =4), and aluminum ( n =1) were included. Meta analysis of the 2 cohort studies showed that lead exposure was not associated with the risk of overweight and obesity in children ( RR=0.76, 95%CI=0.50-1.16, P >0.05). The cross sectional study Meta-analysis results showed that lead exposure was negatively associated with the risk of childhood overweight ( OR=0.70, 95%CI =0.59-0.84, 2 studies) and obesity ( OR=0.71, 95%CI =0.58-0.87, 3 studies); cadmium exposure was negatively associated with the risk of childhood overweight ( OR=0.83, 95%CI =0.73-0.95, 2 studies) and obesity risk( OR=0.70, 95%CI =0.63-0.78, 3 studies); mercury exposure increased the risk of overweight/obesity ( OR=1.42, 95%CI =1.14-1.76, 2 studies) and abdominal obesity ( OR= 1.99, 95%CI =1.45-2.73, 2 studies) in children; the group with the highest concentration of arsenic in urine had a lower risk of developing obesity compared to the group with the lowest concentration ( OR=0.39, 95%CI =0.23-0.65, 1 study), and the group with the highest concentration of aluminum in urine had a lower risk of obesity compared with the group with the lowest concentration ( OR=0.52, 95%CI =0.31-0.86, 1 study)(all P <0.05).
Conclusion
Heavy metal exposure may be a risk factor for overweight and obesity in children and adolescents, but the conclusions are inconsistent and need to be validated in further high quality prospective cohort studies.

OBJECTIVE To observe the clinical efficacy of donafenib combined with programmed death-1 (PD-1) inhibitors and vascular intervention therapy in the treatment of unresectable hepatocellular carcinoma (HCC). METHODS This retrospective study included 165 patients with unresectable HCC who were treated at the Fourth and First Affiliated Hospitals of Soochow University between June 2022 and March 2023. Among them, 89 patients received PD-1 inhibitors (tislelizumab or sintilimab, similarly hereinafter) plus vascular intervention (control group) and 76 patients received donafenib in combination with PD-1 inhibitors and vascular intervention (observation group). Short-term efficacy (3 months after treatment), long-term efficacy (2 years after treatment), the levels of liver function indexes [serum alanine amino-transferase (ALT), aspartate transferase (AST), and total bilirubin (TBil)] and tumor biomarkers [alpha fetoprotein (AFP), carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9), and des-gamma-carboxy prothrombin (DCP)] before treatment and after 3 months of treatment, as well as the occurrence of adverse drug reaction (ADR) during treatment, were compared between the two groups. In addition, overall response rate (ORR) stratified by PD-1 inhibitor type was analyzed. RESULTS After treatment, the ORR was significantly higher in the observation group than in the control group (P<0.05); although the disease control rate was higher in the observation group compared to the control group, the difference was not statistically significant (P>0.05). The median overall survival of patients in the observation group was 16.9 months [95% confidence interval (CI): 14.2 to 19.1 months], which was significantly longer than that in the control group (12.4 months, 95%CI: 10.1 to 15.3 months) (P<0.05). Subgroup analysis result indicated that therapeutic advantage was consistent across both sintilimab and tislelizumab subgroups, with no significant heterogeneity (P>0.1, I 2<0.001%). Before treatment, there were no significant differences in liver function indexes or tumor marker levels between 2 groups (P>0.05). After treatment, both groups showed significant declines in these indicators compared with baseline (P<0.05), with greater reductions observed in the observation group (P<0.05). There were no statistically significant differences in overall incidence of ADR and grade ≥3 ADRs between the two groups (P>0.05). CONCLUSIONS For patients with unresectable HCC, the combination of donafenib, PD-1 inhibitors and vascular intervention therapy may achieve superior clinical outcomes without increasing the risk of treatment-related ADR.

Objective:To develop a self-locked DNAzyme nanoprobe-based fluorescence amplification strategy for wash-free and ultrasensitive detection of breast cancer-derived small extracellular vesicles (sEV).Method:A DNAzyme self-locked probe was designed to recognize the epithelial cell adhesion molecule (EpCAM) specifically expressed on breast cancer-derived sEVs. Upon binding to EpCAM, the DNAzyme-lock structure was opened, restoring the DNAzyme cleavage activity. The activated DNAzyme then cyclically cleaved the RNA site on the substrate strand. Fluorescently labeled substrate strands were used to detect sEVs at varying concentrations, and the detection limit and linear range were determined.Results:The DNAzyme self-locked probe successfully identified breast cancer-derived sEVs and generated a fluorescent signal through cyclic cleavage. The proposed method achieved wash-free detection of sEVs, with the fluorescence intensity showing a strong linear correlation with sEV concentration ( R2=0.98). The linear detection range was 1.0×10 2-1.0×1.0 7 particles/μl, with a detection limit of 59 particles/μl. Conclusion:This study established a wash-free and highly sensitive strategy for quantifying breast cancer-derived sEVs, which provides a promising technical approach for the early diagnosis of cancer.
