Objective:To explore predictive value of pericoronary fat attenuation index(FAI)of the assessment of computed tomography(CT)for coronary restenosis post the surgery of percutaneous coronary intervention(PCI)in elderly patients with coronary heart disease(CHD).Methods:A total of 100 elderly patients with CHD who admitted to Harbin 242 Hospital and underwent PCI from August 2021 to August 2024 were prospectively selected,and they were divided into stenosis group(46 cases)and non-stenosis group(54 cases)based on whether occurred coronary artery restenosis after the surgery.Multivariate logistic regression was used to analyze the influence factors of occurring restenosis in elderly patients with CHD after PCI surgery,and the receiver operating characteristic(ROC)curve was drawn to analyze the predictive value of FAI for restenosis post PCI surgery in patients with CHD.Results:The differences in lipoprotein a,fibrinogen(FIB),total bilirubin(TBIL),total cholesterol(TC),triglyceride(TG),Coronary artery Lesion Complexity Scoring System(SYNTAX)score and FAI were significant between the stenosis group and the non-stenosis group,and the differences were all statistically significant(t=11.819,27.088,38.363,2.632,4.106,7.773,3.231,P<0.05).There were no statistically significant difference in gender,age,body mass index(BMI),blood pressure,basically medical history,and the diameter of implanted stents between the two groups(P>0.05).Multivariate logistic regression analysis showed that lipoprotein a FIB TBIL,TC,TG,SYNTAX score,and FAI index were all influence factors for restenosis post PCI surgery in patients with CHD[OR=4.578(95%CI:2.645～7.932),3.850(95%CI:2.048～7.237),0.145(95%CI:0.052～0.405),6.133(95%CI:1.382～27.219),0.019(95%CI:0.002～0.158),1.264(95%CI:1.150～1.389),1.062(95%CI:1.024～1.102),P<0.05].The ROC curve analysis showed that the area under curve(AUC)value of the ROC curve of the FAI index was 0.760(95%CI:0.666～0.854)in predicting restenosis post PCI surgery,and the sensitivity,specificity,the maximum Youden index and the best cut-off value of that were respectively 89.1%,59.3%,0.484,-79.79,P<0.001.Conclusion:FAI has significant value in predicting restenosis post PCI surgery in elderly patients with CHD,and it can be used as basis of assessing clinical risk.

Objective To explore the value of clinical-MRI radiomics combined model for differentiating borderline ovarian tumor(BOT)from epithelial ovarian cancer(EOC).Methods Totally 139 patients with BOT(BOT group)and 307 patients with EOC(EOC group)confirmed by postoperative pathology and underwent preoperative pelvic MRI were retrospectively enrolled and randomly divided into training set(n=312)and test set(n=134)at a ratio of 7∶3.Multivariable logistic regression was used to identify independent clinical predictors for differentiating BOT and EOC,then a clinical model was constructed.Radiomics features were extracted from the volumes of interest(VOI)of lesions on T2WI,diffusion weighted imaging(DWI)and apparent diffusion coefficient(ADC)images,respectively,and single-sequence and multi-sequence MRI radiomics models were built using extreme gradient boosting(XGBoost)based on data in training set.The optimal MRI radiomics model was selected according to the highest area under the curve(AUC)in test set,and a clinical-MRI radiomics combined model was constructed combined the optimal radiomics model with independent clinical predictors.The performances of clinical model,the optimal MRI radiomics model and the combined model for differentiating BOT and EOC were compared in test set.SHapley Additive exPlanations(SHAP)analysis was applied to interpret key predictive features in the best model.Results Patients' age,carbohydrate antigen 153(CA153)and carbohydrate antigen 125(CA125)were all independent predictors for differentiating BOT and EOC(all P＜0.05).Multi-sequence MRI radiomics model was the optimal MRI radiomics model.The combined model showed superior performance(AUC=0.929)for discriminating BOT and EOC compared with clinical model(AUC=0.881)and multi-sequence MRI radiomics model(AUC=0.871)(both P＜0.05).SHAP beeswarm plot revealed that the top 10 important features of combined model included age,CA153 and CA125,as well as entropy,kurtosis and gray level non-uniformity from ADC and DWI sequences.Conclusion Clinical-MRI radiomics combined model based on multi-sequence MRI radiomics features and clinical features could be used to effectively differentiate BOT from EOC.

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

Objective:To investigate the relationship between oxygen consumption (VO 2), carbon dioxide production (VCO 2), and Oxygen Consumption/lactate (VO 2/Lac) with risk of death in patients with severe ARDS. Methods:A retrospective cohort study method was used, and the study subjects were hospitalized for >5 days adult patients with severe ARDS in the central intensive care unit of Henan Provincial People's Hospital from 1 March 2020 to 30 June 2023. The following patients were excluded: IC test was not completed on the 4th day of ICU admission, IC test results were unreliable, mechanical ventilation duration had exceeded 48 h at the time of ICU transfer or admission, palliative care patients and pregnant and parturient women. Using indirect calorimetry to determine VO 2 and VCO 2 values on the 4th day of admission, reviewing medical records to obtain general condition, disease information, blood gas analysis (including lactate value), diagnostic and therapeutic measures, and following up deaths by telephone and time of death. The primary outcome measure was death at 90 days, and the secondary outcome measure was death at 28 days, length of stay in ICU, total length of stay, and total hospitalization cost. Cox regression analysis and linear regression analysis were used to investigate the relationship between VO 2, VCO 2, VO 2/Lac and primary and secondary outcome indexes. Results:A total of 216 patients were enrolled, 78 patients (36.1%) died and 138 patients (63.9%) survived at 90 days. After correction for confounders, the results of multifactorial Cox regression analysis suggested that compared with the Q4 group, HR (95% CI) for 90-day risk of death in the VO 2 Q1 and Q2 groups was 3.21 (1.38, 7.49) and 3.24 (1.42, 7.38), and HR (95% CI) for 90-day risk of death in the VCO 2 Q1, Q2 and Q3 groups was 5.88 (2.33, 14.84), 4.26 (1. 60, 11.34) and 3.54 (1.34, 9.35), respectively, and the HR (95% CI) for 90-day risk of death in the VO 2/Lac Q1, Q2 and Q3 groups were 8.72 (3.01, 25.25), 8.43 (2.91, 24.47) and 4.04 (1.34, 12.17) respectively. P-trends were all <0.05, indicating that VO 2, VCO 2 and VO 2/Lac were linearly and negatively associated with the risk of 90-day mortality. In addition, VO 2, VCO 2, and VO 2/Lac were negatively associated with 28-day risk of death and higher VO 2/Lac was negatively associated with length of ICU stay. Conclusions:VO 2, VCO 2 and VO 2/Lac were negatively associated with 90-day mortality risk and 28-day mortality risk in patients with severe ARDS and may be independent risk factors predicting mortality risk of such patients.

Objective To verify the performance of an non competitive immune sandwich method(candidate method)in detecting 25(OH)D,and evaluate the measurement agreement of candidate method with liquid chromatography tandem mass spectrometry(LC-MS/MS,reference method).Methods According to the comparison of documents such as China National Accreditation Service for Conformity Assessment(CNAS)-GL037,the precision,linear interval,lower limit of quantitation(LOQ)and accuracy of the method for detecting 25(OH)D were verified.1 073 residual serum samples were collected from March to July 2021 and 25(OH)D was detected by the two methods.Passing-bablok regression,concordance correlation coefficient(CCC),Bland altman plots and Kappa test were used to analyze the consistency and bias.Weighted Kappa test was conducted to evaluate the consistency of two methods for clinical assessment of vitamin D nutritional status.Results The performance of candidate method:the within-run CV was lower than 5%and the in laboratory CV were lower than 10%;test results between 2.88～52.45 ng/ml showed good linear relationship;the lower limit of quantitation was 2.26 ng/ml,the bias of candidate method measuring standard reference materials were within±6%and within 15%measuring vitamin D external quality assessment scheme(DEQAS)samples.The comparison method and the reference method showed good correlation(r=0.965,CCC=0.946)with an average deviation of-1.54 ng/ml(-7.42%).The two methods coincidence rate in judging vitamin D status was 85.96%(918/1 068),and the weighted kappa value was 0.801.Conclusions The candidate method measurement performance met the clinical requirements,and showed good correlation and consistency with the reference method.

Background:Duodenal papillary adenoma is a benign tumor with relatively low incidence but significant carcinogenesis potential.Despite the minimal invasiveness and low complication rate,endoscopic papillectomy is associated with a definite risk of recurrence for duodenal papillary adenoma.Investigating the driver genes of duodenal papillary adenoma and establishing predictive models for recurrence and malignant progression could facilitate the precision medicine.Aims:To identify the key driver genes for tumor occurrence,carcinogenesis and recurrence in duodenal papillary adenoma by integrating multi-dimensional bioinformatics approaches based on transcriptomics data,and validate clinically.Methods:Expression profiles of duodenal papillary adenoma and adenocarcinoma were obtained from the GEO database(including data sets GSE189035,GSE94919,GSE111156,and GSE102208).Differentially expressed genes(DEGs)between adenomatous and normal tissues were screened.Weighted gene co-expression network analysis(WGCNA)and pseudo-time analysis were combined to identify the core genes exhibiting an"initial rise followed by decline"expression pattern during the dynamic progression from normal tissue to adenoma and adenocarcinoma.Functional annotation,immune microenvironment profiling,and protein-protein interaction network analysis were performed to explore the tumor-promoting mechanisms of these core genes.Clinical validation was conducted using immunohistochemistry to estimate the gene expression level and its relationship with tumor recurrence.Results:A total of 469 common DEGs were identified.WGCNA revealed that the blue module(including 1 051 genes)was associated with adenoma development and progression(Cor=-0.29,0.15,and 0.11 for normal tissue,adenoma,and adenocarcinoma,respectively).Intersection with DEGs pinpointed four key genes:SLC12A2,BEST4,SLC37A2,and SOAT2.Pseudo-time analysis demonstrated that only SLC12A2 maintained sustained high expression in both adenoma and adenocarcinoma tissues.KEGG enrichment analysis indicated that SLC12A2 was linked to various malignant pathways(e.g.,PD-1/PD-L1 signaling pathway),and its high expression correlated with the reduced immune cell infiltration(e.g.,γδ T cells,CD8+T cells,etc.).Clinical validation by immunohistochemistry confirmed the trend of initial upregulation and subsequent downregulation of SLC12A2 expression in normal,adenoma,and adenocarcinoma tissues.Patients with tumor recurrence showed higher SLC12A2 expression level(P=0.004);likewise,SLC12A2 high expression was associated with an elevated recurrence risk(P=0.034).Conclusions:SLC12A2 serves as a critical driver of tumorigenesis and progression for duodenal papillary adenoma,and might be a promising biomarker for recurrence prediction.
