Objective:To adapt the English version of exteroceptive body awareness questionnaire (EBA-q) into Chinese, and evaluate its reliability and validity in college students.Methods:English version EBA-q was translated and culturally adapted into Chinese, and the tests were administered from October to December 2024, with valid data collected from 1 071 college students. Item analysis, exploratory factor analysis, confirmatory factor analysis, criterion-related validity analysis, and reliability analysis were conducted by SPSS 23.0 and Mplus 8.3 softwares.Results:(1) The Chinese version of EBA-q contained seventeen items across five factors: visual awareness, tactile awareness, body coordination, awareness of body changes and awareness of clothing fit. The five-factor measurement model fitted the data well ( χ2/ df=2.24, CFI=0.95, TLI=0.94, RMSEA=0.05, SRMR=0.06). (2) The EBA-q scores were positively correlated with the scores of noticing, body listening, public self-consciousness, and private self-consciousness ( r=0.46, 0.36, 0.09, 0.25, all P<0.01). (3)The Cronbach's α coefficient, split-half reliability and test-retest reliability of the Chinese version of EBA-q were 0.79, 0.85 and 0.77, respectively(all P<0.01). Conclusion:The Chinese version of the EBA-q has demonstrated good reliability in assessing external body awareness among college students, but its validity requires further verification.

Objective:To investigate the value of transabdominal bowel ultrasonography (TBUS) in evaluating the active phase of Crohn′s disease (CD) and its complications, and to compare the diagnostic efficacy of the international bowel ultrasound segmental activity score (IBUS-SAS) and the multidetector computed tomography enterography (MDCTE) score in the active phase.Methods:A totle of 103 CD patients who were admitted to the Nanjing Drum Tower Hospital from March 2021 to May 2023 were retrospectively analyzed. All patients underwent TBUS and MDCTE examinations. TBU parameters such as bowel wall thickness (BWT), color Doppler imaging signal (CDS), inflammatory fat (i-fat), and bowel wall stratification (BWS) were recorded. The patients were divided into the remission group and the active group based on the Crohn′s disease activity index. The latter group was further divided into the mild active group and the moderate-to-severe active group.Receiver operating characteristic curves (ROC) were plotted, and the diagnostic efficacy of TBUS parameters and two scoring systems in assessment of the active phase of CD was evaluated by sensitivity, specificity, area under the curve (AUC), and optimal cut-off values. Endoscopic or histopathological results were served as the gold standard for the diagnosis of intestinal strictures. The diagnostic efficacy of TBUS and MDCTE in CD complicated with intestinal stenosis were evaluated by ROC analysis. Spearman correlation analysis was performed to analyze the correlation between TBUS parameters, imaging scores, and clinical laboratory indicators such as erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and faecal calprotectin (FC).Results:In distinguishing the active phase and the remission phase of CD, BWT (a sensitivity of 85.7%, specificity of 90.9%, and cut-off value of 4.4 mm), CDS (a sensitivity of 95.7%, and specificity of 63.6%), IBUS-SAS (a sensitivity of 91.4%, specificity of 84.8%, and cut-off value of 23.8), and MDCTE score (a sensitivity of 77.1%, specificity of 75.8%, and cut-off value of 6.5) had high diagnostic efficacies. In distinguishing mild and moderate-severe active phases of CD, BWT, CDS and i-fat demonstrated high sensitivity (81.4%, 69.8% and 62.8%) and specificity (81.5%, 77.8% and 100.0%); IBUS-SAS (a sensitivity of 83.7%, specificity of 88.9%, and cut-off value of 40.0) and MDCTE score (a sensitivity of 83.7%, specificity of 85.2%, and cut-off value of8.5) had high diagnostic efficacy. In the diagnosis of CD complicated with intestinal stenosis, the AUC, sensitivity, specificity, and accuracy of MDCTE was 0.942, 94.0%, 94.3%, and 94.2%, respectively. The AUC, sensitivity, specificity, and accuracy of TBUS in the diagnosis of CD complicated with intestinal stenosis was 0.952, 96.0%, 94.3%, and 95.1%, respectively. The results of Spearman correlation analysis revealed that BWT, CDS, and i-fat have positively correlated with ESR, CRP, and FC ( r value: 0.252 to 0.451, all P<0.05). Conclusions:TBUS demonstrates good application value in evaluating the activity of CD and intestinal stenosis. IBUS-SAS has the potential application for precise assessment of CD activity.

Objective To investigate the correlation between immune cells and the occurrence of cardiovascular disease(CVD)in patients with human immunodeficiency virus/acquired immunodeficiency syndrome(HIV/AIDS),and to construct a risk prediction model.Methods A total of 280 HIV/AIDS patients treated from June 2024 to August 2025 were selected as the research subjects and divided into a training set(n=200)and a test set(n=80)at a ratio of 5:2.The patients in the training set were subdivided into a CVD subgroup(n=60)and a non-CVD subgroup(n=140)according to whether they developed CVD.The baseline characteristics and immune cells of the two groups were compared,and the longitudinal trajectory changes of immune cells in the CVD subgroup and the non-CVD subgroup were analyzed.LASSO regression analysis was used to screen the independent influencing factors of CVD,multivariate Logistic regression analysis was used to screen the independent risk factors for the occurrence of CVD,and a risk prediction nomogram model was constructed.The area under the receiver operating characteristic(ROC)curve(AUC),Hosmer-Lem show test,calibration curve,and decision curve were used to compare the risk prediction nomogram model with the general cardiovascular risk assessment model,to evaluate its discrimination,goodness-of-fit,and clinical utility.Results There were significant differences in the baseline characteristics and immune cells between the two groups(P<0.05).The longitudinal trajectory plots revealed that the CD4+count,CD8+count,and CD4+/CD8+level in the CVD group exhibited substantial fluctuations,while the trajectories of these parameters in the non-CVD group remained relatively stable.After LASSO regression analysis screened out 11 non-zero coefficient variables,multivariate logistic regression analysis showed that age,hypertension,total cholesterol,smoking,high-sensitivity C-reactive protein,CD4+count at the time of HIV diagnosis,CD8+count at the time of HIV diagnosis,and globulin were all independent influencing factors for the occurrence of CVD in HIV/AIDS patients(P<0.05).The AUC of the risk prediction nomogram model was 0.960 in the training set and 0.914 in the test set,indicating good discrimination of the model.The Hosmer-Lem show test and calibration curve showed good accuracy and consistency of the model,and the decision curve showed a high net benefit value,indicating good clinical utility.Conclusion The CVD risk in HIV/AIDS patients is jointly affected by immune dysfunction and traditional metabolic factors.The risk prediction nomogram model constructed significantly improves the accuracy of risk prediction of CVD and can provide a basis for early identification of high-risk patients and the formulation of individualized intervention strategies.

Objective:To investigate the effect of changes of left ventricular diatolic function immediately after transcatheter aortic valve replacement (TAVR) on the prognosis of TAVR.Methods:A total of 80 patients undergoing TAVR treatment were retrospectively enrolled from October 2017 to February 2023 in the Department of Cardiology of the First Hospital of China Medical University. Demographic data, imaging parameters, laboratory data and operation data were recorded. Patients were followed up at 30 days and 1 year after TAVR through clinic or telephone visits. The changes of diastolic function parameters before and immediately after TAVR were analyzed. When the improvement of left ventricular diastolic function grade≥1 grade was defined as the improvement of diastolic function. Included patients were divided into left ventricular diastolic disfunction (LVDD) improvement group and non-improvement group. The primary endpoint was the composite outcome of 1-year all-cause mortality and cardiovascular rehospitalization. The diffferences of adverse events between two groups were analyzed, and univariate and multivariate Cox regression analysis were used to explore the predictors of the primary adverse events of TAVR.Results:Improvement in LVDD grade was seen in 30 (37.5%) patients immediately after TAVR. Patients with improvement in ≥1 grade of LVDD had less 1-year death/cardiovascular rehospitalization than patients in non-improvement group(6.7% vs 28.0%, P=0.021). Multivariate Cox proportional hazards models showed that improvement in LVDD grade immediately after TAVR was an independent protective factor for 1-year death/cardiovascular rehospitalization ( HR=0.103, 95% CI=0.021-0.502, P=0.005), while diabetes mellitus ( HR=4.035, 95% CI=1.294-12.584, P=0.016), society of thoracic surgeons (STS) score ( HR=1.253, 95% CI=1.015-1.421, P<0.001), intensive care unit (ICU) stay ( HR=1.198, 95% CI=1.012-1.418, P=0.036), and aortic valve area (AVA) ( HR=1.079, 95% CI =1.039-1.121, P<0.001) were independent risk factors for 1-year death/cardiovascular rehospitalization. Conclusions:The improved left ventricular diastolic function is experienced in 37.5% of patients immdiately after TAVR, and patients with improvement in LVDD grade immediately after TAVR has less 1-year death/cardiovascular rehospitalization, which is an independent protective factor for 1-year death/cardiovascular rehospitalization, while diabetes mellitus, STS score, ICU stay and AVA are independent risk factors for 1-year death/cardiovascular rehospitalization.

Objective To propose a modified lung ultrasound score(LUS),and to observe its value for evaluation on severity of acute respiratory distress syndrome(ARDS).Methods Data of lung ultrasound,chest X-ray and so on in 33 sudden ARDS patients were retrospectively analyzed.The patients were divided into moderate-severe group(n=16)and mild group(n=17)according to oxygenation index(OI).The outcomes of LUS,modified LUS and radiographic assessment of lung edema(RALE)score were compared between groups.Receiver operating characteristic(ROC)curves were drawn,the area under the curves(AUC)were calculated to evaluate the efficacy of various image scores for evaluating the severity of ARDS.Pearson correlation analysis was performed to explore the correlations of various image scores with OI,of RALE score with LUS and modified LUS in ARDS patients.Results LUS and modified LUS in moderate-severe group were both higher than those in mild group(both P＜0.05).No significant difference of RALE score was found between groups(P＞0.05).AUC of LUS,modified LUS and RALE score for evaluating the severity of ARDS was 0.809,0.853 and 0.640,respectively.LUS and modified LUS in ARDS patients were moderately negatively correlated with OI(r=-0.570,P=0.001;r=-0.708,P＜0.001),while no obvious correlation of RALE score and OI was found(r=-0.229,P=0.201).RALE score of ARDS patients was moderately positively correlated with both LUS and modified LUS(r=0.588,P＜0.001;r=0.502,P=0.003).Conclusion The above mentioned modified LUS could effectively evaluate severity of ARDS,with better efficacy than LUS and RALE score.

Objective This paper aims to explore patient satisfaction with mobile medical payments in ethnic minority areas and its influencing factors.Methods From May to August 2023,565 ethnic minority patients from 6 villages in 4 ethnic minority autonomous counties in Dehong Prefecture and Pu'er City,Yunnan Province,were selected as research subjects,and 186 Han patients in Kunming were selected as controls.The general information questionnaire,the mobile medical payment will-ingness and attitude survey scale,and the medical cost mobile payment satisfaction survey scale were used to investigate their sat-isfaction with actual situation of medical mobile payment.Additionally,this paper discussed influencing factors affecting satisfac-tion.Results The ethnic minority patients exhibited a significantly lower level of satisfaction compared to the Han patients(39.65±10.43 vs.49.54±7.88,P＜0.05).ethnic minority patients scored significantly lower on the dimensions of satisfac-tion,such as perceived safety,ease of use and usefulness of mobile medical payment compared to the group of Han patients(all P＜0.05).Additionally,they ethnic minority patients showed significantly lower level of willingness and attitude to use mobile medical payment compared to the group of Han patients(P＜0.05).The main factors influencing the significant difference in satisfaction with mobile medical payment were ethnic group,number of hospital visits in previous year,first-time use of mobile medical payment,and educational background(P＜0.05).Conclusion Ethnic minority patients have a low perception of secur-ity,ease of use,and usefulness of mobile medical payments,as well as a low willingness and characteristics for mobile medical payment.Therefore it is necessary to further enhance their experience and satisfaction.In the development of mobile medical pay-ment services hospitals should fully consider the current situation of"illiteracy""semi-illiteracy"and"lack of resources"in re-mote ethnic areas.They should actively develop service platforms and applications suitable for mobile medical payment in ethnic minority areas to continuously enhance service efficiency and quality.

OBJECTIVE: Surgical wounds that can’t complete primary healing three weeks after surgery are called postoperative refractory wounds. Postoperative refractory wounds would bring great physical and life burdens to the patients and seriously affect their quality of life. To investigate the effect of platelet fibrin plasma (PFP) on postoperative refractory wound healing.APPROACH: The composition of PFP was analyzed using blood routine and blood biochemicals. Clinical data were collected that met the inclusion criteria after treatment with PFP, and the efficacy of PFP was evaluated by wound healing rate and days to healing. Next, growth factor content in PFP, PRP, and PPP was analyzed using ELISA, and PFP-treated cells were applied to investigate the effect of PFP on fibroblast and endothelial cell function. RESULTS: PFP component analysis revealed no statistical difference between platelet concentration in PFP and physiological concentration. Clinical statistics showed that PFP treatment was effective in the postoperative refractory wound (four-week wound healing rate [ 90%), significantly better than continuous wound dressing. Meanwhile, our result also proved that PFP treatment significantly enhanced vascularization by upregulated the expression level of CD31 and improved granulation tissue thickness. Activated PFP, PRP, and PPP could continuously release growth factors in vitro and the amount of growth factors released by PRP and PFP was significantly higher than PPP. In vitro studies demonstrated that active PFP could improve cell proliferation, migration, adhesion, and angiogenesis in fibroblasts and endothelial cells.INNOVATION: Physiologically concentrated platelet plasma promoted wound healing and improved related cellular functions. The modified PFP (responsible for accelerating wound healing and enhancing the migration and proliferation of fibroblasts and endothelial cells) was prepared and analyzed for its clinical effectiveness in postoperative refractory wounds. CONCLUSION Physiologically concentrated platelet plasma promoted wound healing and improved related cellular functions. The preparation of PFP could significantly reduce the amount of prepared blood, with a good application value for postoperative wounds. PFP can be considered a treatment option, especially for postoperative refractory wounds.
