The success of implementation research is closely tied to the institution's pre-implementation readiness. This study aims to explore the organizational readiness for change (ORC) and its influencing factors on primary healthcare settings in the implementation of the "Shared Medical Appointment for Diabetes (SMART) in China: design of an optimization trial" and to enhance ORC and provide insights to support the effective implementation of the program. Qualitative interviews and quantitative surveys were conducted to evaluate the ORC level and its influencing factors in 12 institutions implementing the SMART program. The Scale for Assessing the Institution's Readiness to Implement Evidence-Based Practices was utilized to measure ORC levels. Qualitative interviews were conducted among change implementers to gather information regarding the status of influencing factors. Thematic analysis was applied to extract factors from the interview data, and an assessment questionnaire was developed to measure the perceived impact of these factors. A fuzzy-set qualitative comparative analysis (fsQCA) method was employed to identify the influencing factors of ORC and pathways leading to high-level ORC. Seventy implementers from 12 institutions, encompassing administrators, clinicians, and health managers, participated in the interviews and surveys. The median and interquartile of the ORC scores were 105.20 (101.23, 107.33). The fsQCA indicated that a clear understanding of specific tasks and responsibilities, the active engagement of key participants, sufficient preliminary preparation, and the use of audits and feedback mechanisms were critical pathways to a high-level ORC. Conversely, institutions lacking key participants, preliminary preparation, or marginal influence demonstrated a low-level ORC. Before implementing innovation, Coherence and Cognitive Participation were identified as critical factors in influencing ORC. Strong leadership from key participants played pivotal role in enhancing readiness for change and was essential for improving implementation fidelity and overall program success.

This study aimed to localize the workplace readiness questionnaire (WRQ) and validate its applicability for assessing readiness for implementation of evidence-based practices (EBP) in primary care settings in China. The localization of the instrument will provide a practical instrument for assessing organizational readiness for change (ORC). The WRQ was translateed into Chinese version using the modified Brislin translation model, and its cross-cultural validity, content validity, and generalizability were evaluated by the Delphi method, and the expert feedback was evaluated using the item-level content validity index (I-CVI), scale-level content validity index (S-CVI), and corrected Kappa value. The index weights were evaluated by the analytic hierarchical process (AHP). The target users of the scale were invited to quantitatively evaluate its item importance score (IIS), and the surface validity was evaluated by combining the qualitative feedback from their cognitive interviews. To clarify the purpose of the scale, we revised its name to the Organizational Readiness of Implementing Evidence-Based Practices (ORIEBP) Scale. The ORIEBP scale contained five dimensions, which were Change Context, Change Valence, Information Evaluation, Change Commitment, Change Efficiency, and 32 items. After two rounds of the Delphi method to refine the construction of three dimensions and expressions of 11 items, the I-CVI were from 0.73 to 1.00, the Kappa value were from 0.70 to 1.00, and the S-CVI was over 0.92. All evaluation matrices of the hierarchical analysis method met the requirement of consistency ratio (CR < 0.1), and the weights of five dimensions were 0.2083, 0.2022, 0.1907, 0.2193, and 0.1795, in sequence. Nine out of eleven experts identified that items were applicable to other readiness assessment scenarios. The IIS scores for the five dimensions and 32 items were ranged from 2.93 to 3.54, and 2.71 to 3.42, presenting good face validity. The cognitive interview results showed that professional expressions were complex to understand. This study validated the ORIEBP scale and has good content validity and generalizability. The scale can be further improved by expanding its scope of use and validating its structure validity and reliability in different settings.

ObjectiveThis study aims to explore the potential mechanism of the Xiezhuo Jiedu formula in regulating pyroptosis for the treatment of ulcerative colitis (UC) using bioinformatics and in vivo animal experiments. MethodsDifferentially expressed genes (DEGs) in colon tissues of UC patients were retrieved from the Gene Expression Omnibus (GEO) database. Pyroptosis-related genes were obtained from the GEO and GeneCards databases. The intersection of these datasets yielded pyroptosis-related DEGs (Pyro-DEGs). Pyro-DEGs were subjected to Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis using the Metascape database. A protein-protein interaction (PPI) network was constructed using the STRING database. Least absolute shrinkage and selection operator (LASSO) prediction model and receiver operating characteristic (ROC) analysis were conducted to identify core Pyro-DEGs with diagnostic and therapeutic potential. Immune infiltration analysis of the UC datasets was performed using the deconvolution method (CIBERSORT), along with correlation analysis with core Pyro-DEGs. Sixty male Sprague-Dawley (SD) rats were randomly divided into a control group, a model group, high-, medium-, and low-dose groups of Xiezhuo Jiedu formula (26.64, 13.32, 6.66 g·kg-1), and a mesalazine group (0.27 g·kg-1), with 10 rats in each group. UC was established by intrarectal administration of 3,5-trinitrobenzenesulfonic acid (TNBS) dissolved in ethanol. The control and model groups were given distilled water by gavage, while the treatment groups were administered the corresponding drugs for 7 consecutive days. Hematoxylin-eosin (HE) staining was used to observe the colon histopathology. Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of inflammatory factors such as interleukin-1β (IL-1β), IL-10, IL-18, and transforming growth factor-β (TGF-β). Immunohistochemistry (IHC) and Western blot were applied to detect the expression of Caspase-1, gap junction alpha-1 protein (GJA1), peroxisome proliferator-activated receptor gamma (PPARG), and S100 calcium-binding protein A8 (S100A8). Real-time quantitative polymerase chain reaction (Real-time PCR) was utilized to measure mRNA expression of Caspase-1, GJA1, PPARG, and S100A8. Western blot was performed to assess protein expression levels of Caspase-1, GJA1, PPARG, and S100A8. ResultsGEO datasets GSE87466 and GSE87473 yielded 64 Pyro-DEGs. KEGG analysis indicated that these genes were enriched in the NOD-like receptor signaling pathway, tumor necrosis factor (TNF) signaling pathway, and hypoxia-inducible factor 1 (HIF-1) signaling pathway. Four core Pyro-DEGs (Caspase-1, GJA1, PPARG, and S100A8) were identified. Immune infiltration analysis showed that expression of these genes was positively correlated with mast cells, neutrophils, M0 macrophages, M1 macrophages, and dendritic cells. Animal experimental results indicated that compared with the control group, the model group had significantly increased levels of IL-1β and IL-18, significantly decreased levels of IL-10 and TGF-β. The model group showed enhanced Caspase-1, GJA1, and S100A8 staining, and significantly increased mRNA and protein expression of Caspase-1, GJA1, and S100A8 (P<0.01). In contrast, the expression of PPARG was reduced in the model group (P<0.01). After treatment, all dosage groups showed varying degrees of improvement (P<0.05, P<0.01), with the high-dose group showing the most significant improvement (P<0.01). ConclusionCaspase-1, GJA1, PPARG, and S100A8 are core Pyro-DEGs closely associated with the pathogenesis of UC. These genes may collaborate with immune cells such as mast cells, neutrophils, and M0 macrophages to mediate disease development. The Xiezhuo Jiedu formula may regulate the expression of core Pyro-DEGs through the NOD-like receptor, TNF, and HIF-1 core signaling pathways, thereby modulating immune homeostasis in UC rats and effectively alleviating UC.

In order to solve the problems of difficult test, high cost and long cycle in the development of large-scale airborne negative pressure isolation system, the simulation analysis of negative pressure response characteristics is carried out around various aviation conditions such as aircraft ascending, leveling and descending, especially rapid decompression, based on the computational fluid dynamics (CFD) method. The results showed that the isolation cabin could achieve -50 Pa pressure difference environment and form a certain pressure gradient. The exhaust air volume reached the maximum value in the early stage of the aircraft's ascent, and gradually decreased with the increase of altitude until it was level flying. In the process of aircraft descent, the exhaust fan could theoretically maintain a pressure difference far below -50 Pa without working; Under the special condition of rapid pressure loss, it was difficult to deal with the rapid change of low pressure only by the exhaust fan, so it was necessary to design safety valve and other anti-leakage measures in the isolation cabin structure. Therefore, the initial stage of aircraft ascent is the key stage for the adjustment and control of the negative pressure isolation system. By controlling the exhaust air volume and adjusting parameters, it can adapt to the change of low pressure under normal flight conditions, form a relatively stable negative pressure environment, and meet the needs of biological control, isolation and transport.

Traditional Chinese medicine (TCM) represents a paradigmatic approach to personalized medicine, developed through the systematic accumulation and refinement of clinical empirical data over more than 2000 years, and now encompasses large-scale electronic medical records (EMR) and experimental molecular data. Artificial intelligence (AI) has demonstrated its utility in medicine through the development of various expert systems (e.g., MYCIN) since the 1970s. With the emergence of deep learning and large language models (LLMs), AI's potential in medicine shows considerable promise. Consequently, the integration of AI and TCM from both clinical and scientific perspectives presents a fundamental and promising research direction. This survey provides an insightful overview of TCM AI research, summarizing related research tasks from three perspectives: systems-level biological mechanism elucidation, real-world clinical evidence inference, and personalized clinical decision support. The review highlights representative AI methodologies alongside their applications in both TCM scientific inquiry and clinical practice. To critically assess the current state of the field, this work identifies major challenges and opportunities that constrain the development of robust research capabilities-particularly in the mechanistic understanding of TCM syndromes and herbal formulations, novel drug discovery, and the delivery of high-quality, patient-centered clinical care. The findings underscore that future advancements in AI-driven TCM research will rely on the development of high-quality, large-scale data repositories; the construction of comprehensive and domain-specific knowledge graphs (KGs); deeper insights into the biological mechanisms underpinning clinical efficacy; rigorous causal inference frameworks; and intelligent, personalized decision support systems.

ObjectiveTo investigate the safety and feasibility of intra-biliary drainage tube placement after laparoscopic common bile duct exploration in elderly patients with choledocholithiasis, and to provide more options for surgical procedures in the clinical management of elderly patients with choledocholithiasis. MethodsA retrospective analysis was performed for the clinical data of 52 elderly patients with choledocholithiasis who were admitted to Department of Hepatobiliary Surgery, Affiliated Dalian Friendship Hospital of Dalian Medical University, from November 2021 to October 2024. According to the biliary drainage method after surgery, the patients were divided into internal drainage group with 24 patients and T-tube drainage group with 28 patients, and there were 19 patients in each group after propensity score matching. The two groups were compared in terms of perioperative parameters and postoperative complications. The Wilcoxon rank-sum test was used for comparison of continuous data between two groups, and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. ResultsCompared with the T-tube drainage group, the internal drainage group had a significantly shorter length of postoperative hospital stay and a significantly lower volume of postoperative bile loss (Z=-2.845 and -5.633, both P<0.05), while there were no significant differences between the two groups in time of operation, intraoperative blood loss, and drainage tube indwelling time (all P>0.05). There were no significant differences between the two groups in postoperative bile leak, stone recurrence, biliary stricture, and drainage tube-related complications, and the internal drainage group had a significantly lower total complication rate than the T-tube drainage group [1 (5.3%) vs 7 (36.8%), P<0.05]. ConclusionFor elderly patients with choledocholithiasis, intra-biliary drainage tube placement after laparoscopic common bile duct exploration can shorten the length of postoperative hospital stay, reduce bile loss, and lower the incidence rate of postoperative complications, thereby helping to accelerate postoperative recovery.
