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.

Implementation strategies are targeted interventions aimed at promoting the adoption, implementation, and sustainment of research findings or evidence-based practices in routine healthcare. If implementation strategies can precisely match implementation barriers and facilitators, the likelihood of successful implementation will increase. The CFIR-ERIC matching tool, which can match corresponding ERIC implementation strategies based on CFIR barriers, is a convenient and direct tool for developing implementation strategies. This paper provides a detailed overview of the origins and development of the CFIR-ERIC matching tool, outlines its contents and usage, and illustrates how to apply the tool to develop implementation strategies by using a brief smoking cessation intervention project as an example. The paper also discusses the advantages and limitations of using this tool for developing implementation strategies, with the aim of providing methodological reference for other researchers.

Reasonable disciplinary planning is an important prerequisite for the high-quality development of multi-campus hospitals. In order to promote the rational layout and homogeneous management of multi-campus hospitals, a large public hospital explored multi-campus discipline planning from 2021 to 2022 based on preliminary research, following the principles of management integration, layout differentiation, resource optimization, maximum efficiency, and high-quality development, as well as according to the functional positioning of each hospital(headquarters, south, west, north, and infectious disease hospital), the needs of surrounding residents, and resource allocation. This practice had improved the development of advantageous specialties of sub-campus, promoted the innovation of technologies, and improved the overall medical service capacity of the hospital. The number of outpatients/emergency patients in the hospital had increased from 5.013 million in 2020 to 6.7 million in 2023, and the average length of stay had been shortened from 7.76 days to 6.17 days. It had initially achieved a disciplinary development strategy of " grouping, differentiation, and integration", which could provide reference and guidance for other public hospitals to promote the discipline development and construction for multi-campus hospitals.

Objective To assess the clinical value and safety of endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) for duodenal lesions.Methods The data of 12 patients with duodenal space-occupying lesions underwent EMR or ESD from January 2010 to December 2015 in Chinese PLA General Hospital were retrospectively analysed.Results All patients received operation, including 9 male and 3 female with mean age of 50.0 years(33.0-62.0 years).There were 8 lesions in duodenal bulb and 4 in descending part.The mean diameter of the lesions was 1.2 cm (0.5-3.0 cm).Three lesions were originated from mucosa, of which 2 were high-grade intraepithelial neoplasia and 1 was villous/tubular adenoma.Nine lesions were located in submucosa, including 3 cases of neuroendocrine neoplasm, 1 case of stromal tumor, 1 liomyoma case, 1 lipoma case, 1 case of Brunner glands adenoma, 1 case of ectopic pancreas, and 1 inflammatory lesion.One patient had perforation with rate of 8.3%(1/12) and was recovered after conserved treatment.The bleeding was very little during operation.No infection or stenosis happened.The mean hospitalized time was 6.0 days (1.0-12.0 days) after operation.No recurrence was found during 23.8 months(3.0-73.0 months) of follow-up.Conclusion EMR and ESD are effective and safe for treatment of duodenal space-occupying lesions.

Objective To evaluate the efficacy of interventional catheter drainage combined with ozone therapy for the management of postoperative enterocutaneous fistula. Method A total of 70 patients with postoperative enterocutaneous fistula were enrolled and divided into group A (35, conventional surgical treatment) and group B (35, interventional catheter drainage and ozone therapy). Clinical efficiency, hospital stays, hospital expenses and complications were compared. Follow-up observations of the infection score in 2 groups before and after treatment (3 days, 1 week, 2 weeks and 1 month) were also compared. Results 30 cases in group A recovered (85.7%), and 28 cases in group B recovered (80.0%), the result of which shows no statistic significance. The hospital stays and expense in group B were significantly lower than those in group A. 4 cases of group A suffered from incision complications , 2 intra-abdominal hemorrhage , 1 severe pneumonia and 1 septic shock. 2 cases in group B suffered from stomachache. The differences can be shown significantly. The infection score between the two groups shows no significant difference, but the score was found to be obviously lower after treatment than before. The infection score decreased by an average of 19.9 in group A and 23.5 in group B,indicating a better anti-infective effect in group B. Conclusion Interventional catheter drainage combined with ozone therapy for the management of postoperative enterocutaneous fistula is safe and effective, with lower hospital stays and expense.

OBJECTIVETo investigate the effects of CysLT receptor agonist leukotriene D4(LTD4) and antagonists on activation of microglia BV2 cells.

METHODSThe expression of CysLT1 and CysLT2 protein was determined by Western blotting and immunostaining in microglia BV2 cells. BV2 cells were pretreated with or without CysLT1 receptor selective antagonist montelukast, CysLT2 receptor selective antagonist HAMI 3379, or CysLT1/CysLT2 receptor dual antagonist BAY u9773 for 30 min, then the cells were treated with LTD4 for 24 h. Cell viability was detected by MTT reduction assay. Phagocytosis and mRNA expression of IL-6 were determined by fluorescent bead tracking and RT-PCR, respectively.

RESULTSIn BV2 cells, LTD4 did not affect proliferation but significantly enhanced phagocytosis and increased IL-6 mRNA expression in a concentration-dependent manner. LTD4 at 100 nmol/L induced a 1.4-fold increase of phagocytic index and a 2-fold up-regulation of IL-6 mRNA expression (P<0.01). HAMI 3379 and BAY u9773 (100 nmol/L) further increased LTD4-induced phagocytosis; BAY u9773 and montelukast decreased LTD4-induced IL-6 mRNA expression, while HAMI 3379 had no effect on that.

CONCLUSIONLTD4 activates BV2 cells in vitro and enhances IL-6 mRNA expression mediated by CysLT1 receptor, LTD4 induces phagocytosis which might be negatively regulated by CysLT2 receptor in BV2 cells.
