To explore the advantages of traditional Chinese medicine （TCM） and integrative TCM-Western medicine approaches in the treatment of diabetic microvascular complications （DMC）， refine key pathophysiological insights and treatment principles， and promote academic innovation and strategic research planning in the prevention and treatment of DMC. The 38th session of the Expert Salon on Diseases Responding Specifically to Traditional Chinese Medicine， hosted by the China Association of Chinese Medicine， was held in Beijing， 2024. Experts in TCM， Western medicine， and interdisciplinary fields convened to conduct a systematic discussion on the pathogenesis， diagnostic and treatment challenges， and mechanism research related to DMC， ultimately forming a consensus on key directions. Four major research recommendations were proposed. The first is addressing clinical bottlenecks in the prevention and control of DMC by optimizing TCM-based evidence evaluation systems. The second is refining TCM core pathogenesis across DMC stages and establishing corresponding "disease-pattern-time" framework. The third is innovating mechanism research strategies to facilitate a shift from holistic regulation to targeted intervention in TCM. The fourth is advancing interdisciplinary collaboration to enhance the role of TCM in new drug development， research prioritization， and guideline formulation. TCM and integrative approaches offer distinct advantages in managing DMC. With a focus on the diseases responding specifically to TCM， strengthening evidence-based support and mechanism interpretation and promoting the integration of clinical care and research innovation will provide strong momentum for the modernization of TCM and the advancement of national health strategies.

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.

Ursodeoxycholic acid(UDCA)is a naturally occurring,low-toxicity,and hydrophilic bile acid(BA)in the human body that is converted by intestinal flora using primary BA.Solute carrier family 7 member 11(SLC7A11)functions to uptake extracellular cystine in exchange for glutamate,and is highly expressed in a variety of human cancers.Retroperitoneal liposarcoma(RLPS)refers to liposarcoma originating from the retroperitoneal area.Lipidomics analysis revealed that UDCA was one of the most significantly down-regulated metabolites in sera of RIPS patients compared with healthy subjects.The augmentation of UDCA concentration(≥25 μg/mL)demonstrated a suppressive effect on the proliferation of liposarcoma cells.[15N2]-cystine and[13Cs]-glutamine isotope tracing revealed that UDCA impairs cystine uptake and glutathione(GSH)synthesis.Mechanistically,UDCA binds to the cystine transporter SLC7A11 to inhibit cystine uptake and impair GSH de novo synthesis,leading to reactive oxygen species(ROS)accumulation and mitochondrial oxidative damage.Furthermore,UDCA can promote the anti-cancer effects of ferroptosis inducers(Erastin,RSL3),the murine double minute 2(MDM2)inhibitors(Nutlin 3a,RG7112),cyclin dependent kinase 4(CDK4)inhibitor(Abemaciclib),and glutaminase inhibitor(CB839).Together,UDCA functions as a cystine exchange factor that binds to SLC7A11 for antitumor activity,and SLC7A11 is not only a new transporter for BA but also a clinically applicable target for UDCA.More importantly,in combination with other antitumor chemotherapy or physiotherapy treatments,UDCA may provide effective and promising treatment strategies for RLPS or other types of tumors in a ROS-dependent manner.

Objective:To explore the feasibility of RadCalc automatic planning validation system in the Monaco treatment plan system.Methods:The RadCalc automatic validation system was debugged,and the imaging data of 107 patients with tumors on head(29 cases),breast(28 cases),lung(28 cases)and abdomen(22 cases)who received radiotherapy at Xuanwu Hospital of Capital Medical University from 2021 to 2023 were screened.The dose γ passing rates were tested for all patients.The RadCalc automatic validation system was used to validate the dose γ passing rate under the 3%/2 mm and 3%/3 mm criteria of the radiotherapy plan,and the measured results were compared with those from ArcCHECK and MatriXX phantom.Results:The dose γ passing rates of all debugged test field were more than 97%.In the dose test of clinical plan of 107 patients,the mean value of all dose γ passing rate was larger than 96%under the 3%/2mm criteria,and that was larger than 98%under the 3%2 mm.There were significant differences in the dose γ passing rates under 3%2 mm and 3%3mm criteria of head plan,and under 3%3 mm criteria of breast plan between patients and ArcCHECK phantom who were measured by RadCalc automatic validation system,and the differences were statistically significant(t=8.02,7.79,3.32,P<0.05).There were no significant differences in the γ-passing rate under 3%/2 mm and 3%/3 mm criteria of breast plan and abdomen plan between patients and ArcCHECK phantom who were measured by RadCalc automatic validation system(P>0.05).In volumetric intensity modulated arc therapy(VMAT)plan,there were significant differences in dose γ passing rate under 3%/2 mm and 3%/3 mm criteria between patients and ArcCHECK phantom who were measured by RadCalc automatic validation system(t=4.61,5.16,P<0.05),while there were not statistical significance in these indicators between them in intensity modulated radiation therapy IMRT plans(P>0.05).Conclusion:The measured results of the RadCalc automatic validation system has favorable consistency with the measured results of ArcCHECK and MatriXX phantom.The RadCalc automatic validation system can be used in dose validation of clinical plan.

Objective To understand the clinical applicability and implementation of expert consensus on the implementation and removal of protective restraints in psychiatry,and to provide references for promoting the standardized practice of psychiatric protective restraints and updating the consensus.Methods By the convenience sampling method,a questionnaire survey was conducted among nurses from 480 hospitals in 30 provinces from June 15 to July 15,2024.The survey was conducted using the instrument for evaluating clinical applicability of guide-lines(version 2.0)and a self-compiled questionnaire on the clinical implementation of the restraint consensus.Results A total of 7,844 valid questionnaires were collected,with a valid questionnaire recovery rate of 93.78％.The results of clinical applicability scoring showed that the consensus had the lowest availability score(64.72％)and the highest acceptability score(76.74％).The results showed that nurses' receiving training and the level of their hospitals were the main influencing factors for scores in various dimensions(P＜0.05).4,774 participants(87.42％)believed that the application of consensus could enhance the standardization of nurses' restraint operations.The safety rate of the restraint consensus was 79.51％,and the economic ratio was 76.87％.Among the evaluators,1,739(22.17％)believed that there were implementation obstacles in the consensus.Conclusion The clinical applicability of the consensus is relatively good,and the application of the consensus helps to improve the standardization of clinical operations.In the future,efforts should be made to strengthen the promotion and training of the consensus,develop hierarchical promotion strategies according to the characteristics of medical institutions,and improve the quality of evidence for the consensus,so as to further enhance the clinical application effect of the consensus.

AIM:To explore suitable methods for the induction and cryopreservation of mouse bone marrow-derived macrophages(BMDMs).METHODS:Mouse fibroblasts(L929 cells)were cultured under varying conditions of temperature,seeding density,and serum concentration.The concentration of macrophage colony-stimulating factor(M-CSF)in the cell supernatant was measured using ELISA to determine the optimal conditions.Mouse bone marrow cells were extracted,and a differential adherence method was employed to pre-culture the bone marrow cells for 4 h,followed by flow cytometry to assess the proportion of resident macrophages.Flow cytometry was utilized to assess the ratio of F4/80 positive cells among the suspended and adherent cells.Induction of BMDMs was conducted using L929 cell supernatant or recombinant M-CSF for 7 d,and flow cytometry was applied to evaluate the proportion of F4/80 and CD11b double-positive cells.The morphologic changes during cell induction were observed under an inverted microscope,and the phagocytic ca-pacity and inflammatory response levels of BMDMs derived from C57BL/6N and C57BL/6J mice were evaluated using neu-tral red and ELISA methods.The cells were immediately cryopreserved after extraction,and then induced after recovery,or cryopreserved after successful induction and recovered.The cell morphology was observed under an inverted micro-scope,cell viability was assessed using the CCK-8 method,and phagocytic ability was measured using the neutral red method.RESULTS:The M-CSF concentration in the supernatant from L929 cells cultured at 33℃,10%fetal bovine se-rum(FBS)for 7 d was rich.Following 4 h of pre-culture,the proportion of F4/80 positive cells in adherent cells was sig-nificantly higher than that in suspended cells(P＜0.01).After 7 d of induction with L929 cell supernatant or recombinant M-CSF,the proportions of F4/80+CD11b+cells showed no significant difference(P＞0.05).Compared with the BMDMs derived from C57BL/6J mice,those from C57BL/6N mice exhibited stronger phagocytic capacity(P＜0.01),and released lower levels of TNF-α(P＜0.01)and IL-6(P＜0.05),and higher levels of IL-1β(P＜0.05).Compared with the BMDMs that were induced after recovery from initial cryopreservation,those cryopreserved immediately after extraction and in-duced upon recovery exhibited better macrophage morphology,higher cell viability(P＜0.01),and enhanced phagocytic ability(P＜0.01).CONCLUSION:The supernatant from L929 cells cultured at 33℃,10%FBS for 7 d is rich in M-CSF,successfully inducing bone marrow cells to differentiate into mouse BMDMs.The differential adherence method for pre-culturing can eliminate resident macrophages from the original bone marrow.The phagocytic capacity and inflammato-ry response levels differ between BMDMs derived from the C57BL/6N and C57BL/6J mouse subtypes.Cryopreserving bone marrow cells immediately after extraction and subsequently inducing them upon recovery is a preferable method for BMDM cryopreservation.

Objective To analyze risk factors of acute cardio-cerebrovascular accidents in elderly patients with lower extremity fracture,and to construct a risk prediction diagram model.Methods A retrospective analysis was conducted on the clinical data of 510 elderly patients with lower extremity fractures,and the patients were divided into the occurrence group and the non-occurrence group based on the occurrence of acute cardiovascular and cerebrovascular accidents during the postoperative hospitalization.Univariate and multivariate Logistic regression analysis was used to analyze risk factors affecting acute cardiovascular and cerebrovascular accidents in elderly patients with lower extremity fracture,and the risk prediction model was constructed and verified.Results A total of 52 cases of acute cardio-cerebrovascular accidents occurred during hospitalization in 510 patients(10.20%).Age,ASA grade Ⅲ ratio,preoperative concurrent cerebrovascular disease,postoperative pneumonia ratio and postoperative bed time≥5 days ratio were higher in the occurrence group than those in the non-occurrence group(P＜0.05).Multivariate Logistic regression analysis showed that age,ASA grade Ⅲ,preoperative concurrent cardiovascular and cerebrovascular disease,and postoperative pneumonia were risk factors for acute cardio-cerebrovascular accidents in elderly patients with lower limb fracture(P＜0.05).Multivariate Logistic regression analysis was used to screen risk factors as predictive variables to build a risk early warning histogram model for acute cardio-cerebrovascular accidents.The total score ranged from 103 to 168 points,corresponding to a risk range of 0.1 to 0.9 points.Receiver operating characteristic curve(ROC)curve results showed that the area under the curve(AUC)of this model for predicting acute cardiovascular and cerebrovascular accidents was 0.980(95%CI:0.964-1.000),and discrete choice approach(DCA)showed that when the risk threshold was 0.2-0.6,the prediction model of this column graph had a good clinical advantage.Conclusion The risk diagram model constructed based on risk factors has good predictive value for the occurrence of acute cardio-cerebrovascular accidents after lower extremity fracture in elderly patients.
