Objective:To develop and evaluate a medical visual question answering (VQA) model for neonatal lung ultrasound (LUS) images to enhance intelligent auxiliary diagnosis of neonatal pulmonary diseases.Methods:Using data from neonates admitted to Beijing Obstetrics and Gynecology Hospital, Capital Medical University (January 2023 to December 2024), an image-question-answer dataset comprising 251 LUS images was constructed [43 pneumonia (17.1%), 42 neonatal respiratory distress syndrome (16.7%), 83 transient tachypnea (33.1%), and 83 normal (33.1%) images] with a four-tier medical question-answer framework. Building upon the Qwen2.5-VL-7B base model and integrating LoRA fine-tuning with chain-of-thought prompting, we developed the NLUS-VQA model to enhance visual-language semantic alignment and enable stepwise clinical reasoning, achieving efficient small-sample adaptation. Model performance was comprehensively assessed through natural language generation metrics (BLEU-4, ROUGE-1/2/L), qualitative evaluation of characteristic recognition, and clinical consistency analysis.Results:(1) Quantitative evaluation demonstrated that NLUS-VQA achieved scores of 22.38 (BLEU-4), 48.26 (ROUGE-1), 22.40 (ROUGE-2), and 37.20 (ROUGE-L), representing significant improvements over baseline models. (2) Qualitatively, the model exhibited strong performance in identifying lung consolidation, coalescent B-lines, and snowflake signs, with its chain-of-thought strategy enhancing clinical interpretability and answer accuracy. (3) Clinically, NLUS-VQA achieved a Cohen's Kappa coefficient of 0.78 and diagnostic accuracy of 80.8% (21/26), indicating substantial agreement with clinical experts.Conclusion:The NLUS-VQA model demonstrates robust interpretability in recognizing key sonographic patterns (e.g. lung consolidation, confluent B-lines, and snowflake signs), providing a scalable framework for small-sample medical image analysis, though diagnostic performance on complex conditions remains limited by dataset scale and minority class representation.

Point-of-care testing (POCT) provides key support for clinical decision-making through rapid detection. This article introduces the development background of POCT in the field of pre-hospital emergency, as well as the development status of POCT in Hangzhou City, and analyzes the problems of quality management. Pre-hospital emergency medical institutions in Hangzhou City have been equipped with POCT equipment, and the test items include blood glucose, cardiac troponin, etc. The implementation rates of internal quality control, comparison test, and proficiency testing were 58.2%, 50.3% and 42.6%, respectively. POCT quality management has problems such as unclear responsibility subjects, insufficient professional personnel, and a lack of standardization of the process. It is proposed to build a hierarchical collaborative management system, strengthen the double access mechanism of personnel and equipment, implement the whole process quality control, and build a digital management platform, so as to provide the reference for the high-quality development of POCT in pre-hospital medical emergency institutions.

Objective:To investigate the impact and clinical value of preoperative intra-aortic balloon pump(IABP)placement on the occurrence of postoperative atrial fibrillation(POAF)in elderly high-risk patients with coronary artery disease undergoing off-pump coronary artery bypass grafting(CABG).Methods:A retrospective cohort study was conducted, selecting 128 elderly(age≥60 years)patients with coronary artery disease who underwent isolated off-pump CABG and met high-risk criteria(≥2 high-risk factors)at Beijing Tongren Hospital.According to the occurrence of POAF, patients were divided into the POAF group(38 cases)and the non-POAF group(90 cases). Preoperative baseline data, preoperative IABP usage, intraoperative and postoperative indicators were collected and compared between the two groups.Univariate analysis was used to screen for differential variables, and multivariate logistic regression analysis was performed to identify the independent risk factors for POAF, focusing on the role and impact of preoperative IABP placement on POAF occurrence.Results:Among the 128 patients included, the incidence of POAF in patients with preoperative IABP placement was lower than that in patients without preoperative IABP placement[12.12%(4/33) vs.35.79%(34/95), χ2=6.512, P=0.011]; the preoperative IABP usage rate in the POAF group was significantly lower than that in the non-POAF group[10.53%(4/38) vs.32.22%(29/90), χ2=5.488, P=0.019]; the proportion of patients with preoperative left ventricular ejection fraction(LVEF)<40% in the POAF group was significantly higher than that in the non-POAF group[23.68%(9/38) vs.10.00%(9/90), χ2=4.140, P=0.042]; and the preoperative creatinine level in the POAF group was also significantly higher than that in the non-POAF group[(90.62±29.45)μmol/L vs.(81.31±20.18)μmol/L, t=2.066, P=0.041]. Multivariate logistic regression analysis showed that preoperative LVEF<40% was an independent risk factor for POAF occurrence( OR=11.862, 95% CI: 1.083-129.875, P=0.043), while preoperative IABP placement was an independent protective factor for POAF occurrence( OR=0.095, 95% CI: 0.016~0.583, P=0.011). The comparison of intraoperative and postoperative indicators between the two groups showed that multiple indicators in the POAF group were significantly worse than those in the non-POAF group.In terms of intraoperative indicators, the mean graft blood flow(mGF)of the graft vessels in the POAF group was lower[(18.25±8.84)ml/min vs.(21.24±7.13)ml/min, t=2.015, P=0.046], while the pulsatility index(PI)was higher(2.64±1.36 vs.2.18±1.07, t=2.045, P=0.043). In terms of postoperative laboratory indicators, the level of cardiac troponin I(cTnI)on the first postoperative day in the POAF group[(15.69±11.32)μg/L vs.(11.46±10.07)μg/L, t=2.092, P=0.038], the highest postoperative creatinine level[(128.23±74.29)μmol/L vs.(96.18±48.32)μmol/L, t=2.897, P=0.004], and the highest blood lactic acid level within 24 hours[(1.78±0.53)mmol/L vs.(1.54±0.62)mmol/L, t=2.085, P=0.039]were all significantly higher.In terms of postoperative recovery indicators, the duration of vasoactive drug use[(46.41±32.08)h vs.(36.21±22.39)h, t=2.058, P=0.042], mechanical ventilation time[(16.72±11.64)h vs.(12.19±9.68)h, t=2.275, P=0.025], and intensive care unit(ICU)stay time[(73.48±60.20)h vs.(54.89±39.29)h, t=2.070, P=0.040]in the POAF group were all significantly longer.The LVEF before discharge in the POAF group was also significantly lower than that in the non-POAF group[(43.08±16.24)% vs.(48.49±13.08)%, t=1.986, P=0.049]. Conclusions:Preoperative LVEF<40% is an independent risk factor for POAF occurrence after off-pump CABG in elderly high-risk patients with coronary artery disease, and preoperative prophylactic IABP placement can significantly reduce the occurrence of POAF in this population.

(2) Qualitatively, the model exhibited strong performance in identifying lung consolidation, coalescent B-lines, and snowflake signs, with its chain-of-thought strategy enhancing clinical interpretability and answer accuracy. (3) Clinically, NLUS-VQA achieved a Cohen's Kappa coefficient of 0.78 and diagnostic accuracy of 80.8% (21/26), indicating substantial agreement with clinical experts.Conclusion:The NLUS-VQA model demonstrates robust interpretability in recognizing key sonographic patterns (e.g. lung consolidation, confluent B-lines, and snowflake signs), providing a scalable framework for small-sample medical image analysis, though diagnostic performance on complex conditions remains limited by dataset scale and minority class representation.

Objective:To investigate the etiological mechanism in single small subcortical infarction (SSSI) with different imaging features.Methods:The patients registered in a database of ischemic stroke in the Department of Neurology of the First Affiliated Hospital of Zhengzhou University from January 2016 to December 2019 were analyzed. According to the lowest slice (LS) and the total number of involved slices (TNS) on diffusion-weighted imaging, the SSSI was divided into 3 types: proximal SSSI (pSSSI; LS≤2), distal and large SSSI (dl-SSSI; LS>2, TNS>2) and distal and small SSSI (ds-SSSI; LS>2, TNS≤2). The clinical and imaging features among 3 different lesion patterns were compared by using χ 2 test, Kruskal-Wallis H test and multiple Logistic regression analysis, etc. Results:In the 3 groups of ds-SSSI ( n=205), dl-SSSI ( n=157) and pSSSI ( n=166), the prevalences of parent artery disease (PAD)[10.7% (22/205) , 19.1% (30/157) , 42.8% (71/166), respectively, χ 2=54.89, P<0.001], coronary artery disease [8.3% (17/205), 14.0% (22/157), 16.9%(28/166), respectively, χ 2=6.44, P=0.040] and severe white matter hyperintensities (sWMHs)[58.0% (119/205), 43.3% (68/157), 41.0% (68/166), respectively, χ 2=12.94, P<0.001], the level of serum homocysteine (Hcy)[18.01 (13.54, 25.56), 16.03 (12.50, 21.09), 14.72 (11.12, 19.14) μmol/L, respectively, H=19.36, P<0.001], and the National Institutes of Health Stroke Scale (NIHSS) score[2(1, 3), 3(1, 4), 3(2, 6), respectively, H=39.53, P<0.001] showed statistically significant differences. Multiple Logistic regression analysis showed that compared with dl-SSSI patients, the lesion pattern of patients with higher proportion of PAD ( OR=3.12, 95% CI 1.86-5.24, P<0.001) was closer to pSSSI; the lesion pattern of patients with higher serum Hcy level ( OR=1.02, 95% CI 1.00-1.04, P=0.046) or higher proportion of sWMHs ( OR=1.79, 95% CI 1.12-2.86, P=0.015) was closer to ds-SSSI, and the lesion pattern of patients with higher proportion of PAD ( OR=0.50, 95% CI 0.27-0.93, P=0.029) or higher NIHSS score ( OR=0.84, 95% CI 0.77-0.92, P<0.001) was closer to dl-SSSI. Conclusions:The pathogenesis of ds-SSSI tends to be cerebral small vessel disease. The pathogenesis of pSSSI is related to atherosclerosis. The patients with dl-SSSI have the intermediate characteristics of pSSSI and ds-SSSI and may be unstable.

Objective:To summarize the experience of ambulance medical support in the 19th Hangzhou Asian Games, and provide reference for the ambulance medical support work of large-scale sports events in the future.Methods:According to the actual situation of the Asian Games, the objectives of the medical support were determined according to the principles of highlighting the key points and overall consideration. All kinds of ambulances were allocated according to the principles of combining dynamic and static and regional linkage. The ambulance support was divided into the event side and the city side,with the regional security vehicle as the supplement of the event side and the guarantee of the city side, the implementation of "one pavilion one policy", "one game one policy", "one place one policy" and "one vehicle one plan", and the interconnection of medical points (rooms), designated hospitals, management and command personnel and ambulances were realized through the Asian Games Intelligent Emergency Medical Support Syetem (EMSS).Results:Between September 16, 2023, 08:00, and October 9, 2023, 08:00, a total of 207 ambulances were deployed during the 19th Hangzhou Asian Games. Of these, 88 (42.5%) were at competition venues, 11 (5.3%) at training venues, 30 (14.5%) at non-competition venues, and 78 (37.7%) were regional support vehicles. Among them, 20 venue ambulances participated in regional support tasks during idle times. Ambulances transported patients from event sites 345 times, with the highest number of transports occurring at competition venues (187 times) and the fewest in the assisting city of Huzhou (6 times). The highest ambulance utilization rate was 70.5% at competition venues, while training venues, non-competition venues, and regional support ambulances had utilization rates of 45.5%, 53.3%, and 42.3%, respectively. The median age of transported individuals was 26 (21, 36), with a majority being male (59.1%). Athletes comprised 52.5% of transports, while staff and spectators accounted for 39.7% and 7.8%, respectively. Joint injuries were the most common condition among transported individuals, totaling 58 cases (16.8%). Regional support ambulances participated in 75 transfers and replacements, with 17 (22.7%) transfers and 58 (77.3%) replacements.Conclusions:This study confirms the feasibility and efficiency of the Asian Games' ambulance support plan, highlighting the crucial role of EMSS. The study suggests the need to strengthen medical support for staff, in addition to athletes.

Objective:To construct an intelligent medical emergency information platform for the 19th Hangzhou Asian Games events and evaluate its practical application.Methods:Addressing the medical support demands for Asian Games, based on the " Emergency medical service system for large-scale social activities" developed by Zhejiang Laboratory, a collaborative team comprising Hangzhou Emergency Center, the Second Affiliated Hospital of Zhejiang University,Zhejiang Lab and College of Biomedical Engineering and Instrument Science of ZhejiangUniversity developed an intelligent medical emergency information platform for the Asian Games. This system was implemented during the 19th Hangzhou Asian Games, collecting basic information, initial diagnosis locations, prognoses, severity grading, and occurrences of infectious diseases for all patients treated at support locations from September 16th to October 8th, 2023. The Modified Early Warning Score (MEWS) was employed for assessing patient conditions, and a symptom monitoring system was used to alert the occurrence of infectious diseases. Post-event, a satisfaction evaluation (on a 5-point scale) regarding the system's application was conducted.Results:The successful construction of the intelligent medical emergency information platform comprised a data dashboard display platform, a comprehensive command system on the management center, and a mobile platform covering on-site medical support, ambulances, and designated hospitals. ①A total of 11 068 patients were treated using this system, including 2 979 athletes, 3 429 staff members, 1 421 volunteers,1 051 spectators, and 2 188 others. The proportion of patients seeking treatment due to illnesses was significantly higher than those due to injuries. Among injury-related cases, athletes constituted 41.37%, while staff accounted for 32.5% of illness-related cases. ②The area under the ROC curve for MEWS regarding hospitalization rates was 0.81 for disease patients and 0.60 for injury patients. ③ There were 211 reported cases of infectious diseases during the event, constituting 1.91% of all treated cases.④ Satisfaction ratings: User-friendliness scored 4.47, completeness of functions scored 4.28, data security scored 4.38, and data accuracy scored 4.49. Compared to traditional paper-based reporting methods, 98.11% of users found the system more convenient, 92.45% were satisfied overall, and the recommendation rating was 4.36.Conclusions:The study findings confirm the critical role played by the information platform in enhancing comprehensive, accurate, timely, secure medical support information dissemination for the Asian Games and in early warning and control of infectious diseases.
