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.

Objective To investigate the effects of digital platform construction in departmental Party branches on the or-ganizational stronghold role of primary-level Party organizations.Methods Under the leadership of the hospital Party committee,the Radiology Department Party Branch launched the development of a"Party building+Services"digital platform in July 2021,facilitating a comprehensive integration of political and operational activities.This study retrospectively compared the differences in the indicators of party-building and the disciplinary development,mainly including Party-building effectiveness,team cohe-sion,management efficiency,clinical services,scientific research outputs,and educational performances between three-years pre-and post-implementation.Additionally,it also summed up the impact of an electronic platform development on the role of primary-level Party organizations as a combat bastion.Results Post-implementation metrics demonstrated statistically significant improvements in such indicators of Party organization building and disciplinary development as primary-level Party building effec-tiveness,team cohesion,management efficiency,scientific research outputs,and educational performances(all P＜0.05).Conclusion The establishment of an electronic platform within the department fosters deep integration and intelligent empower-ment of Party building and operational activities,enhances the quality of Party building,and promotes the advancement of disci-plines,thereby reinforcing the role of primary-level Party organizations as effective combat bastions.

[Objective]To clearly identify the difference between rescue injuries and agonal injuries and to avoid duplicate identifications and misidentifications.[Methods]Based on the forensic pathological data of 5 923 cases of death cause identification from 2013 to 2022 in Sun Yat-sen University Forensic Identification Center and Guangzhou Tianhe District Branch of Guangzhou Public Security Bureau,this study retrospectively studied the characteristics of rescue injuries and agonal injuries seen in cause of death identification and their influence on cause of death identification.[Results]Among all the 5 923 cases,640 cases were found to have rescue injuries or agonal injuries,and 624 cases received treatment,of which 609 cases were found to have rescue injuries(97.60%),44 cases were found to have agonal injuries,and 13 cases were found to have both types of injuries.Among the 640 cases,441 were male and 199 were female.The age of death was discontinuously distributed from 0 to 95 years old.The leading cause of death was disease,followed by mechanical injury and asphyxia.The main manifestations of rescue injuries were rib and sternum fractures,soft tissue injuries in the prechest area or face,and pericardial rupture.The most common injuries in agonal stage were falling after unconsciousness,inhalation of foreign body in respiratory tract or multiple violent injuries.Among the 640 cases,19 cases were repeatedly identified,including 15 cases of rescue injuries,6 cases of agonal injuries,and 2 cases of both types of injuries.Compared with the cases where neither type of injuries was detected,the repeated identification rate of treatment injuries and agonal injuries was significantly increased(χ2=4.04,P=0.044;χ2=43.49,P<0.001).Among the 640 cases,11 cases(1.72%)were misidentified as the initial injuries in the first identification,and 13 cases had combined rescue injuries or agonal injuries that were involved in death.[Conclusions]By elucidating the epidemiological characteristics of the two types of injuries,this study proved that the two types of injuries were associated with higher rates of repeated identification and misidentification,which provided a reference for reducing repeated identification and misidentification and improving the accuracy of cause of death identification.

Objective:To explore the value of dual-layer spectral CT virtual monoenergetic images (VMI) in contrast-enhanced abdominal CT scans with reduced contrast medium volume in pediatric tumor patients.Methods:The study is a self-matched case-control study. From January to October 2024, pediatric patients admitted to Shandong Cancer Hospital with abdominal tumors who underwent low contrast dose spectral CT contrast-enhanced scans during follow-up were prospectively included. A total of 47 patients aged (6.2±2.2) years (4-14 years) were enrolled. Usual contrast dose enhanced CT served as the conventional-dose group, while the follow-up low-dose spectral CT scans employed a protocol with half the contrast agent dose (low-dose group). Images were reconstructed as conventional CT images and VMI at 45, 55, and 65 keV. Using muscle as the reference background, differences in CT values and contrast-to-noise ratio (CNR) in the aorta, kidneys, liver, and spleen were compared between the low-dose group and conventional-dose group. Multi-group comparisons were performed using the Friedman test. Post-hoc pairwise comparisons were conducted with Bonferroni correction for P-values. Results:CT values and CNRs for all measured regions progressively increased with decreasing keV levels in spectral CT VMI. Significant overall differences were found in CT values and CNRs for the aorta, kidneys, liver, and spleen among the low-dose group (all VMIs) and the conventional-dose group (all P<0.001). At 65 keV VMI in the low-dose group, both CT values and CNRs (except for the liver CNR) were significantly lower than those in the conventional-dose group (all adjusted P<0.05). At 55 keV VMI in the low-dose group, CT values and CNRs for all regions did not show statistically significant differences compared to the conventional-dose group (all adjusted P>0.05). At 45 keV VMI in the low-dose group, CT values for all structures and CNR for the spleen were significantly higher than those in the conventional-dose group (all adjusted P<0.05). However, no statistically significant difference was found in CNRs for the aorta, kidneys, and liver (adjusted P=1.000, 0.313, and 0.503, respectively). Conclusion:When the contrast dose is halved, spectral CT 45 keV VMI enhances CT attenuation values and CNR in the abdomen of pediatric tumor patients, while 55 keV VMI provides image quality comparable to that of conventional-dose CT.

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.

Objective: To examine the causal association and potential mechanisms between bone mineral density in different age groups and primary malignant bone tumor based on two sample Mendelian randomization (MR), so as to provide a reference for the prevention and treatment of primary malignant bone tumor. Methods: The genome-wide association study (GWAS) of bone mineral density was obtained from the GEFOS database,which included 66 628 subjects divided into five age groups (0-15, 15-30, 30-45, 45-60, and >60 years) based on the phases of human bone development. The GWAS of primary malignant bone tumor was sourced from the FinnGen database, including 648 cases and 378 749 controls. Using bone mineral density of five age groups as the exposure and primary malignant bone tumor as the outcome, an MR analysis was performed with the inverse-variance weighted (IVW) method. Sensitivity analysis were conducted using Cochran's Q test, MR-Egger regression, MR-PRESSO test and MR Steiger test. The potential mechanisms underlying the causal association between bone density and primary malignant bone tumors were explored using Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. Results: The MR analysis results showed that there was a negative causal association between bone density and primary malignant bone tumors in the 30-45 age group (OR=0.301, 95%CI: 0.126-0.721). No statistically significant associations between bone density and primary malignant bone tumors were found in the 0-15, 15-30, 45-60, and >60 age groups (all P>0.05). Sensitivity analysis did not detect heterogeneity, pleiotropy (all P>0.05) and reverse causality. KEGG enrichment analysis revealed that genes highly associated with bone density and primary malignant bone tumors were enriched in the mTOR signaling pathway and the Wnt signaling pathway, among which Low Density lipoprotein Receptor Related protein 5 and Wnt Family Member 16 are key regulatory genes. Conclusion The decrease in bone mineral density among individuals aged 30-45 may increase the risk of primary malignant bone tumors through the mTOR signaling pathway and the Wnt signaling pathway.
