The important studies in the field of extracorporeal life support (ECLS) in 2024 focused on the application of cardiac support technologies in acute myocardial infarction (AMI) with cardiogenic shock (CS): veno-arterial extracorporeal membrane oxygenation (V-A ECMO) has not shown advantages in either short- or long-term outcomes and may increase the risk of bleeding and vascular complications; in contrast, micro-axial flow pumps demonstrate potential in improving mortality. The effects of veno-venous extracorporeal membrane oxygenation (V-V ECMO) combined with prone positioning on severe acute respiratory distress syndrome (ARDS) remain uncertain. The survival benefit of extracorporeal cardiopulmonary resuscitation (ECPR) in out-of-hospital cardiac arrest (OHCA) patients has been further validated. The potential benefits of extracorporeal carbon dioxide removal (ECCO2R) require further investigation. Additionally, new guidelines released in 2024 focus on Neurological monitoring and management during ECMO, as well as the Definition and management of right ventricular injury during veno-venous ECMO. ECMO management requires more refined strategies, including optimized oxygenation targets, anticoagulation, blood transfusion, and weaning strategies to improve patient outcomes.

Objective To study the technological innovation efficiency of the pharmaceutical manufacturing industry and its relationship with industrial development.Methods The data from the China Statistical Yearbook,China High Tech Statistical Yearbook,the statistical yearbook data of regional statistical bureaus was collected to evaluate the technological innovation efficiency of the pharmaceutical manufacturing industry in 29 provinces and cities in China based on the super-efficiency three-stage SBM model.And then,the spatial econometric model and panel quantile regression model were used to conduct empirical research.Results The average technological innovation efficiency of the pharmaceutical manufacturing industry in 29 provinces was 0.49,with the east greater than the central region,and the central region greater than the west.The technological innovation efficiency of pharmaceutical manufacturing industry has a significant positive correlation with its industrial development,and the marginal effect of this effect shows a law of diminishing in regions with low to high development level,and there is a significant positive spatial spillover effect of pharmaceutical manufacturing industry development between regions.Conclusions The central and western provinces,which have relatively weak pharmaceutical manufacturing industries,should improve the innovation environment and talent supply to enhance the efficiency of technological innovation.Concerted efforts should be made to vigorously promote exchanges,connections,and cooperation between regions with strong technological innovation efficiency and their surrounding areas.And it is imperative to encourage top domestic pharmaceutical companies to significantly increase their investment in the research and development of innovative drugs and to actively engage in international competition.

Objective To evaluate the application of high-resolution magnetic resonance vessel wall imaging(HRMR-VWI)in identifying high-risk features of intracranial atherosclerotic plaques,and to analyze the correlation between plaque characteristics and stroke recurrence under varying degrees of stenosis.Methods The data from 368 patients with intracranial atherosclerotic stenosis(ICAS)across two centers were retrospectively analyzed.Based on the degree of stenosis,all patients were categorized into mild-to-moderate stenosis group(luminal stenosis<70%,n=155)and severe stenosis group(luminal stenosis≥70%,n=213).HRMR-VWI images and clinical information of the patients were collected and analyzed,and the culprit plaques were quantitatively analyzed.Univariate and multivariate logistic regression analyses were employed to identify the risk factors for stroke recurrence,and the predictive performance was evaluated using the area under the curve(AUC)of the receiver operating characteristic(ROC)curve.Results Higher normalized wall index(NWI)[odds ratio(OR)=1.082,95%confidence interval(CI)1.050-1.118,P<0.05]and the presence of intraplaque hemorrhage(IPH)(OR=1.843,95%CI 1.120-3.036,P<0.05)were risk factors for stroke recurrence in all patients.And these two factors were also significant in the mild-to-moderate stenosis group(NWI:OR=1.088,95%CI 1.009-1.186,P<0.05;IPH:OR=4.049,95%CI 1.227-16.065,P<0.05).A predictive model for stroke recurrence was constructed using the combination of IPH and NWI,with the best performance in the mild-to-moderate stenosis group(AUC=0.813,95%CI 0.723-0.906).Conclusion In patients with luminal stenosis<70%,the increase of NWI and the presence of IPH have been validated as significant and effective indicators for predicting stroke recurrence,demonstrating notable predictive performance.In contrast,among patients with luminal stenosis≥70%,the utility of plaque characteristics in predicting stroke recurrence is relatively lower,indicating that the correlation between plaque characteristics and stroke recurrence varies across different degrees of stenosis.

Objective:To develop a treatment-related quality of life scale for Chinese patients with multiple myeloma (MM) and to test its reliability and validity.Methods:The initial scale was constructed through a literature search, Delphi expert correspondence, and cognitive testing. This study conducted a preliminary survey of 379 patients with MM and a formal survey of 865 patients from the hematology departments of 155 hospitals nationwide from February 2024 to March 2024. The final scale was obtained after conducting item analysis and reliability and validity tests on the initial scale.Results:The constructed scale contains 36 items covering six domains: physiological, psychological, social, treatment side effects, general health, and others. In the preliminary survey, the Cronbach’s alpha coefficient of each item ranged from 0.597 to 0.939, and the test-retest reliability was 0.747 ( P<0.001). Exploratory factor analysis extracted eight common factors with a cumulative variance contribution of 60.058%. In the formal survey, the Cronbach’s alpha coefficient of each item ranged from 0.484 to 0.930, and the test-retest reliability was 0.835 ( P<0.001). Confirmatory factor analysis revealed a comparative fit index of 0.750, a root-mean-square error of approximation of 0.090, and a root-mean-square residual of 0.067. Conclusion:The treatment-related quality of life scale for Chinese patients with MM designed in this study exhibited good reliability and validity, reflecting the impact of treatment on the quality of life of patients. This scale can provide a reference to clinicians for assessing the disease status of patients.

Objective To explore the barriers of implementing collaborative chronic wound management within medical consortium and provide references for ensuring continuous care for chronic wound patients.Methods Using purposive and snowball sampling methods,14 specialist nurses participating in chronic wound collaborative management across medical consortium in 7 provinces/municipalities(Beijing,Shanghai,Zhejiang,Sichuan,etc.)were selected for semi-structured interviews between December 2023 and January 2024.Data were analyzed via content analysis.Results Totally 4 themes and 8 subthemes were identified,including management and organizational level(the management system needs improvement;the function of medical information mutual recognition has not been fully realized),resource and technology level(there are insufficient nursing resources at the grassroots hospitals;the specialized nursing capabilities of wound nurses at grassroots hospitals need to be enhanced),patient and demand level(patients' trust is insufficient;patients' concepts are rigid),information technology and support level(the informatization construction of grassroots hospitals lags behind;the intelligence of information systems is insufficient).Conclusion Wound specialist nurses encounter various difficulties when participating in the coordinated management of chronic wounds within the medical consortium.The management and organizational system constraints hinder the effectiveness of the nursing coordination;the resource and technology gap affects the implementation of graded wound care in the region;the lack of patient trust and misconceptions intensify the resistance to coordination;the lagging in information technology construction limits the innovative development of nursing coordination.

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.

Objectives:To investigate whether the use of inlays and onlays made of 3 different materials respectively increases the risk of distal root fracture in mandibular second molars with alveolar bone resorption after root canal treatment.Methods:A 3D fi-nite element analysis(3D FEA)model of distal alveolar bone resorption in mandibular second molars was established using Micro-CT,Mimics21.0,geomagic and ANSYS17.0.3 types of materials(resin nanoceramic Lava ultimate,lithium disilicate ceramics e.max CAD and yttria-stabilized zirconia ceramic e.max Zir CAD)inlays and onlays were utilized for the application of vertical and 45° force loadin respectively.The von-Mises stress distribution on the models was analyzed.Results:Among the models,it was ob-served that cusp-covering onlay model demonstrated minimal Von Mises stresses at distal roots.Lava Ultimate exhibited the highes levels of Von Mises stress than other 2 materials,the stress was more concentrated towards upper parts of distal roots.Conclusion:When distal caries occur below the CEJ of mandibular second molars and are accompanied by alveolar bone resorption,the utilization of cusp-covering onlays and resin nanoceramics can reduce the risk of root fracture in the distal apical region.
