Objective The aim is to understand the common scenarios of non-medical use of prescription opioids(NMUPO)and analyze the potential facilitating and hindering factors in the regulatory process of NMUPO from the perspective of healthcare professionals.Methods Healthcare professionals in local hospitals were surveyed through a two-stage purposive sampling from June to August 2022 in Ningbo,China.The survey was conducted using a semi-structured questionnaire on topics,and thematic analysis were used to identify and summarise key themes and patterns.Results A total of 75 participants were included,the average age was(43.9±7.2)years,and 54(72.0%)were male.The most common NMUPO scenarios involved middle-aged males pretending acute severe pain to obtain injectable opioids.The facilitating and hindering factors related to the regulation of NMUPO can be categorized into three types:institutional governance,technical support,and individual behaviors.At the institutional level,facilitating factors included strict national prescribing policies and local"narcotic drug card"systems,while barriers comprised incomplete lists of controlled substances.At the technological support level,facilitating factors included the establishment of regional health information platforms,while barriers included the lack of standardized prescription guidelines and diagnostic decision-support tools.At the individual level,facilitating factors included the public's cautious attitude toward drug misuse,while barriers included strained doctor-patient relationships.Conclusion China still faces significant challenges in addressing NMUPO and urgently needs to improve the existing regulatory system.It is recommended that reforms be carried out in areas such as pharmaceutical control mechanisms,drug treatment and rehabilitation services,preventive health education activities,and the optimized use of health information systems.

Objective To assess the prognostic value of serum lysine hydroxylase 3(PLOD3)and cytokeratin 19 fragment(CYFRA21-1)in predicting the efficacy of three-dimensional brachytherapy in patients with pulmonary metastases.Methods A total of 102 patients with lung metastases who underwent three-dimensional brachytherapy at our hospital were selected as the lung metastasis group from August 2021 to August 2023.During the same period,a control group consisting of 60 healthy individuals who underwent physical examinations was selected.The lung metastasis group was further divided into an effective group(n=66)and an ineffective group(n=36)based on therapeutic outcomes.Enzyme-linked immunosorbent assay was employed to measure the levels of serum PLOD3 and CYFRA21-1.Multiple logistic regression analysis was conducted to identify factors influencing the efficacy of three-dimensional brachytherapy in the lung metastasis group.Receiver operating characteristic(ROC)curves were used to assess the predictive value of serum PLOD3 and CYFRA21-1 for treatment efficacy.Results The levels of serum PLOD3 and CYFRA21-1 in the case group were(34.47±6.17)μg/L,(27.85±5.14)μg/L,respectively,which exhibited significantly higher values compared to those observed in the control group(7.26±2.21)μg/L,(9.31±2.46)μg/L(P<0.05).A positive correlation was found between serum PLOD3 and CYFRA21-1 in the Lung metastasis group(r=0.667,P=0.000).Logistic regression analysis revealed that multiple metastatic lesions along with elevated serum levels of PLOD3 and CYFRA21-1 were identified as risk factors for the efficacy of three-dimensional brachytherapy in patients with lung metastases(P<0.05).Furthermore,when combined with three-dimensional brachytherapy,the area under the curve(AUC)for serum PLOD3 and CYFRA21-1 was calcu-lated as 0.868,demonstrating a superior performance compared to individual measurements of either serum PLOD3 alone(AUC=0.815)or CYFRA21-1 alone(P<0.05).Conclusions The levels of serum PLOD3 and CYFRA21-1 are elevated in patients with lung metastases,exhibiting a significant correlation with the efficacy of three-dimensional brachytherapy.The combined utilization of these two biomarkers demonstrates a robust predictive value for treatment efficacy in patients suffering from lung metastases.

Objective: To improve the efficiency and standardization of preoperative anemia diagnosis and treatment by establishing a systematic intelligent management platform for preoperative anemia. Methods: A multidisciplinary collaborative model was adopted to develop a preoperative anemia management system that integrates intelligent early warning, standardized treatment pathways, and quality control. The system utilizes natural language processing technology to automatically capture laboratory data and establish evidence-based medical decision support functions. A pre-post study design was employed to compare changes in preoperative anemia screening rates, preoperative anemia intervention rates, reasonable use of iron supplements, and perioperative red blood cell transfusion rates before and after system implementation. Results: After system implementation, the standardization of anemia diagnosis and treatment significantly improved: 1) Screening effectiveness: The anemia screening rate increased to 50.00% (an increase of 27.24%); 2) Intervention effectiveness: The anemia treatment rate rose to 56.30% (an increase of 14.02%); 3) Treatment standardization: The reasonable use rate of iron supplements increased to 55.33% (an increase of 21.02%); the red blood cell transfusion rate decreased to 18.29% (a decrease of 4.07%), and the amount of red blood cell transfusions was reduced by 291 units. Conclusion: This system achieves full-process management of preoperative anemia through information technology, significantly enhancing the standardization of diagnosis and treatment as well as intervention effectiveness, providing an effective solution for perioperative anemia management.

Objective:To analyze the clinical features and prognosis of patients with lymphoplasmacytic lymphoma/Waldenstr?m macroglobulinemia (LPL/WM) transformed into diffuse large B-cell lymphoma (DLBCL) .Methods:This study retrospectively analyzed the clinical data of five patients with LPL/WM transformed to DLBCL diagnosed and treated at a multicenter hospital in Hunan Province from December 2020 to April 2023. Clinical manifestations, treatment regimens, and therapeutic efficacy before and after the transformation were compared.Results:Of the five patients, four were male and one was female, with a median age of 64.0 (57.0–80.0) years, all of whom had abnormally increased β 2-microglobulin levels at diagnosis, and two were combined with increased lactate dehydrogenase levels. The MYD88 L265P mutation was detected in 4 patients, whereas 1 carried the FAT1 and NOTCH1 mutations, and none demonstrated CXCR4 mutations. Three patients were negative for the TP53 mutation, and two were not tested. Before transformation, three patients were treated with Bruton tyrosine kinase inhibitor therapy, and one patient was treated with the bendamustine plus rituximab regimen. All patients eventually transformed into non-growth center-derived DLBCL, with a median time to conversion of 11.8 (4.0–19.0) months, and most of them presented with weight loss, lymph node enlargement, splenomegaly, and extranodal involvement. Posttransformation, the patients were mainly treated with the rituximab, cyclophosphamide, hydroxydaunorubicin, oncovin, and prednisone (R-CHOP) regimen, with an optimal outcome of partial remission. Disease progression occurred in 4 of the patients, with a median overall survival of 16.8 (10.0–26.0) months. Conclusion:Transformation from LPL/WM to DLBCL is rare. Patients should remain highly vigilant for transformation if they develop rapidly enlarging lymph nodes and/or newly involved lymph nodes, worsening systemic symptoms, and declining body mass. R-CHOP regimen may induce a partial response in some cases; however, the overall prognosis remains poor.
