Objective: Blood safety surveillance is a critical measure for the objective assessment of blood quality and enhancing transfusion safety. This study aims to comprehensively understand the current status of blood safety surveillance and management in blood collection and supply institutions in Sichuan Province, systematically analyze existing problems and vulnerabilities, and provide a basis for optimizing management strategies and improving capabilities to ensure blood safety. Methods: The Blood Safety Surveillance questionnaire was designed, covering adverse donor reaction reporting, management of adverse events, and transfusion adverse reaction feedback. An online survey was conducted via Questionnaire Star platform among 21 blood collection and supply institutions in the province, gathering information on management systems, process implementation, and utilization of monitoring data. The collected data were organized and statistically analyzed using Excel. Results: The questionnaire response rate and validity rate were both 100%. Blood collection and supply institutions in Sichuan Province have generally established a blood safety surveillance system and achieved positive outcomes. Regarding adverse events in blood collection and supply, 95.24% (20 institutions) have established reporting procedures, and 66.67% (14) collect information through multiple channels such as internal reports, external reports, and statistical trend feedback. A total of 90.48% (19) institutions regularly summarize and analyze adverse event data, and 85.71% (18) produce reports with improvement recommendations based on this analysis.71.43% (15) institutions implement reward and penalty measures, and 71.43% (15) report underreporting or omission due to accountability or performance concerns. In terms of monitoring adverse blood donation reactions, all blood collection and supply institutions have established full-process management systems.76.19% (16) collect data through multiple approaches, including on-site donation records, voluntary donor reports, and donor follow-ups. Adverse reactions were followed up in 95.24% (20) of institutions with 65% (13) completing follow-ups within 24 hours.80.95% (17) have established investigation procedures, while 66.67% (14) believe underreporting or omission still occurs. All blood collection and supply institutions regularly compile statistics on adverse donation reactions. Of these, 85.71% (18) institutions providing feedback to management departments and 90.48% (19) analyzing the data and making recommendations.76.19% (16) institutions use monitoring data for return donor management and targeted care, and 71.43% (15 stations) incorporate it into management reviews. Regarding adverse transfusion reactions, 95.24% (20) institutions have established and implemented procedures for isolating, recalling, and tracing of problematic blood units. However, only 42.86% (9) have established feedback mechanisms of adverse transfusion reaction with hospitals, and only 19.05% (4) support direct reporting via information systems.47.62% (10) institutions regularly analyze adverse transfusion reaction data, and 19.05% (4) provide feedback and recommendations to relevant hospitals. All blood collection and supply institutions reported challenges in collecting hospital feedback, citing complexities in data collection and reporting processes. Conclusion: Blood safety surveillance systems have been preliminarily established in Sichuan Province. However, further strengthening is still required, including conducting in-depth data analysis and utilization, standardizing the configuration of emergency medications and equipment, and improving feedback mechanisms for adverse transfusion reactions. To improve the overall level of blood safety management, it is recommended to strengthen closed-loop data management, improve feedback mechanisms between blood collection and supply institutions and hospitals, foster a non-punitive reporting culture, and systematically advance the regionalization and standardization of the monitoring system. These efforts will contribute to sustainably improving the overall effectiveness and sustainability of blood safety management.

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:The incidence of infections in patients with malignant hematologic diseases is extremely high and significantly affects their prognosis.Identifying early and precise biomarkers for infection is crucial for guiding the treatment of infections in these patients.Previous studies have shown that procalcitonin(PCT)can serve as an early diagnostic marker for bloodstream infections in patients with malignant hematologic diseases.This study aims to compare serum PCT levels in these patients with different pathogens,disease types,infection sites,and severity levels. Methods:Clinical data and laboratory results of infected patients with malignant hematologic diseases treated at the Department of Hematology,the Third Xiangya Hospital of Central South University from January 2018 to August 2023 were collected.General patient information was retrospectively analyzed.Serum PCT levels were compared among patients with different pathogens,types of malignant hematologic diseases,infection sites,and infection severity;Receiver operator characteristic(ROC)curves were used to determine the cut-off values and diagnostic value of serum PCT levels in diagnosing bloodstream infections versus local infections and severe infections versus non-severe infections.Mortality rates after 4-7 days of anti-infective treatment were compared among groups with rising,falling,and unchanged PCT levels. Results:A total of 526 patients with malignant hematologic diseases were included.The main pathogens were Gram-negative bacteria(272 cases,51.7%),followed by Gram-positive bacteria(120 cases,22.8%),fungi(65 cases,12.4%),viruses(23 cases,4.4%),and mixed pathogens(46 cases,8.7%).The main types of malignant hematologic diseases were acute myeloid leukemia(216 cases,41.1%),acute lymphoblastic leukemia(107 cases,20.3%),and lymphoma(93 cases,17.7%).Granulocyte deficiency was present in 68.3%(359 cases)of the patients during infection,with severe infection in 24.1%(127 cases).Significant differences in serum PCT levels were found among patients with different types of pathogens(P<0.001),with the highest levels in Gram-negative bacterial infections.Significant differences in serum PCT levels were also found among patients with different types of malignant hematologic diseases(P<0.05),with the highest levels in lymphoma patients.Serum PCT levels were significantly higher in systemic infections and severe infections compared to local infections and non-severe infections(both P<0.001).ROC curve analysis showed that the cut-off values for diagnosing bloodstream infections and severe infections were 0.22 and 0.28 ng/mL,with areas under the curve of 0.670 and 0.673,respectively.After 4-7 days of anti-infective treatment,the mortality rates of the PCT declining,PCT unchanged,and PCT rising groups were 11.9%,21.2%,and 35.7%,respectively,and pairwise comparisons were statistically significant(all P<0.05). Conclusion:PCT can be used as an auxiliary indicator for early identification of different pathogens,infection sites,and severity levels in patients with malignant hematologic diseases combined with infections.Dynamic monitoring of PCT levels after empirical antibiotic treatment provides important guidance for assessing patient's prognosis.

Objective:To explore the role of long non-coding RNA rhabdomyosarcoma 2 associated transcript(lncRNA RMST)and microRNA-24-3p(miR-24-3p)in proliferation,migration and invasion of oral squamous cell carcinoma cells(OSCCs).Methods:The RMST expression in head and neck squamous cell carcinoma(HNSC)was analyzed by UALCAN data base.qRT-PCR was used to detect the expression of RMST and miR-24-3p in 5 human OSCC cell lines.CAL27 cells were in vitro cultured and allocated into con-trol group,pcDNA3.1 group(vector),pcDNA3.1-RMST+mimics-NC group(overexpression of RMST+negative control of miR-24-3p)and pcDNA3.1-RMST+miR-24-3p mimics group(overexpression of RMST+miR-24-3p).Dual luciferase reporter assay was per-formed to analyze the interaction between RMST and miR-24-3p.MTT assay,wound-healing and transwell assay were applied to de-tect the proliferation,migration and invasion of the cells.Western blot and qRT-PCR were conducted to measure the expression of E-cadherin,N-cadherin and c-myc in the cells.Results:RMST level were down-regulated in HNSC tissues and OSCC cell lines(P＜0.01).While miR-24-3p level was elevated in OSCC cell lines(P＜0.01).miR-24-3p was identified and confirmed as a potential binding partner to RMST.miR-24-3p level was lower in pcDNA3.1-RMST group than in pcDNA3.1 group(P＜0.01).The prolifera-tion,migration and invasion abilities of CAL27 cell in pcDNA3.1-RMST+mimics-NC group were lower than in pcDNA3.1 group(P＜0.01).While those of CAL27 cells in pcDNA3.1-RMST+miR-24-3p mimics group were higher than in pcDNA3.1-RMST+mimics-NC group(P＜0.01).Compared with pcDNA3.1 group,pcDNA3.1-RMST+miR-24-3p mimics showed higher expression of E-cad-herin,lower expression of N-cadherin and c-myc(P＜0.01).Compared with pcDNA3.1-RMST+miR-24-3p mimics group,pcD-NA3.1-RMST+miR-24-3p mimics group showed lower expression of E-cadherin,higher expression of N-cadherin and c-myc(P＜0.01).Conclusion:Down-expressed RMST may suppress the proliferation,migration and invasion progression of OSCC cells through targeting miR-24-3p.

Objective: To investigate the correlation between magnetic resonance imaging-based vertebral bone quality (VBQ) score and screw loosening after dynamic pedicle screw fixation with polyetheretherketone (PEEK) rods, and evaluate its predictive value. Methods: A retrospective analysis was conducted on the patients who underwent dynamic pedicle screw fixation with PEEK rods from March 2017 to June 2022. Data on age, sex, body mass index, hypertension, diabetes, hyperlipidemia history, long-term smoking, alcohol consumption, VBQ score, L1–4 average Hounsfield unit (HU) value, surgical fixation length, and the lowest instrumented vertebra were collected. Logistic regression analysis was employed to assess the relationship between VBQ score and pedicle screw loosening (PSL). Results: A total of 24 patients experienced PSL after surgery (20.5%). PSL group and non-PSL group showed statistical differences in age, number of fixed segments, fixation to the sacrum, L1–4 average HU value, and VBQ score (p < 0.05). The VBQ score in the PSL group was higher than that in the non-PSL group (3.56 ± 0.45 vs. 2.77 ± 0.31, p < 0.001). In logistic regression analysis, VBQ score (odds ratio, 3.425; 95% confidence interval, 1.552–8.279) were identified as independent risk factors for screw loosening. The area under the receiver operating characteristic curve for VBQ score predicting PSL was 0.819 (p < 0.05), with the optimal threshold of 3.15 (sensitivity, 83.1%; specificity, 80.5%). Conclusion The VBQ score can independently predict postoperative screw loosening in patients undergoing lumbar dynamic pedicle screw fixation with PEEK rods, and its predictive value is comparable to HU value.

ObjectiveTo evaluate the clinical efficacy of Qimai Qinlou prescription in the treatment of elderly community-acquired pneumonia （CAP） （non-severe） with Qi and Yin deficiency and phlegm-heat obstructing lung syndrome and its impact on immune-inflammatory factors. MethodA total of 120 eligible patients were randomly divided into an observation group （60 cases） and a control group （60 cases）. Both groups received intravenous cefoxitin sodium. In addition， the observation group received oral Qimai Qinlou prescription， while the control group received an oral placebo simulating Qimai Qinlou prescription. The treatment course was 14 days. The disappearance time of major clinical symptoms and signs was recorded. Traditional Chinese medicine （TCM） syndrome scores and the Clinical Research Outcome （CAP-CRO） scale scores for pneumonia of the two groups were compared. Chest computed tomography （CT） scans were performed， and peripheral blood levels of procalcitonin （PCT）， interleukin-6 （IL-6）， serum amyloid A （SAA）， high-sensitivity C-reactive protein （hs-CRP）， CD4⁺， CD8⁺， and CD4⁺/CD8⁺ were measured. The conversion rate to severe condition during hospitalization， readmission rate within 30 days after discharge， and safety evaluation were recorded. ResultAfter treatment， the observation group showed significantly shorter time of fever， cough， expectoration， and disappearance time of lung moist rales than the control group （P<0.01）. The TCM syndrome scores， CAP-CRO scores in all dimensions， and total scores in both groups were significantly reduced as compared with those before treatment （P<0.01）. After treatment， the observation group had a more significant reduction than the control group （P<0.01）. The levels of PCT， IL-6， SAA， and hs-CRP in both groups were significantly reduced as compared with those before treatment （P<0.01）. After treatment， the observation group showed a more significant reduction than the control group （P<0.01）. There was no statistically significant difference in the changes of CD4⁺， CD8⁺， and CD4⁺/CD8⁺ in the control group before and after treatment. However， in the observation group， CD4⁺ and CD4⁺/CD8⁺ levels significantly increased （P<0.01）， while CD8⁺ level significantly decreased （P<0.01） after treatment. After treatment， CD4⁺ and CD4⁺/CD8⁺ in the observation group significantly increased （P<0.01）， and CD8⁺ significantly decreased as compared with those in the control group （P<0.01）. At 7， 10， and 14 days after treatment， the curative rates in the observation group were 53.33% （32/60）， 85.00% （51/60）， and 91.67% （55/60）， respectively， which were higher than 31.67% （19/60）， 61.67% （37/60）， and 68.33% （41/60） in the control group （χ²=5.763， 8.352， 10.208， P<0.05）. After treatment， the total effective rate of CT scanning in the observation group was 93.33% （56/60）， higher than 80.00% （48/60） in the control group （χ²=4.615， P<0.05）. The conversion rate to severe condition during hospitalization in the observation group was 3.33% （2/60）， lower than 15.00% （9/60） in the control group （χ²=4.904， P<0.05）. The readmission rate within 30 days after discharge in the observation group was 8.33% （5/60）， lower than 23.33% （14/60） in the control group （χ²=5.065， P<0.05）. No serious adverse drug reactions were observed in either group during the treatment period. ConclusionQimai Qinlou prescription can enhance immune function， alleviate inflammatory reactions， significantly relieve clinical symptoms， shorten the duration of the disease， improve the curative rate and CT scanning efficacy， prevent disease progression， reduce the readmission rate in the short term， and is clinically safe for the treatment of elderly patients with non-severe CAP with Qi and Yin deficiency and phlegm-heat obstructing lung syndrome. It is worthy of further research and application.
