Abstract:Objective To evaluate the predictive efficacy of multiparametric dynamic contrast-enhanced MRI(DCE-MRI)radiomics for histological grading in invasive ductal carcinoma(IDC)of the breast.Methods A total of 183 cases of IDC confirmed by pathology the First Affiliated Hospital of Jinzhou Medical University were included(139 cases of grade Ⅰ-Ⅱ and 44 cases of grade Ⅲ),and they were divided into training and test sets at a ratio of 7:3.Preprocessing,3D segmentation and feature extraction were conducted on T2WI,DWI,ADC and enhanced S1-S5 phases;features were selected through t-test,LASSO and variance inflation factor,and random forest(RF),support vector machine(SVM),logistic regression(LR),naive Bayes(NB)and multi-model fusion(RF+SVM+LR)were constructed.Receiver operating characteristic(ROC)curves were used to calculate the area under the curve(AUC),with DeLong's test comparing model performance.Decision curve analysis(DCA)and calibration curves assessed clinical applicability.Results The S3 phase(third post-contrast phase)demonstrated optimal performance among single-sequence models;in the testing set,RF,SVM,LR,and NB models trained on S3-phase features achieved AUCs of approximately 0.81,0.84,0.85,and 0.75,respectively;the multi-model fusion(S3 phase)achieved an AUC of 0.88.In the training set,RF and SVM outperformed LR,while LR surpassed NB(most comparisons P＜0.05);RF marginally outperformed SVM(P＞0.05).In the testing set,only the fusion model showed significantly higher performance than NB(P＜0.05).DCA revealed that RF and LR multiparametric models yielded the highest net clinical benefit,with excellent calibration.Conclusion Multiparametric DCE-MRI radiomics can effectively differentiate high-and low-grade IDC.The S3-phase radiomic features and multi-model fusion strategy demonstrated superior predictive performance,highlighting their potential for clinical application.

Abstract:Objective To explore the mechanism of Ginkgo biloba against tongue cancer based on network pharmacology and cellular experiments.Methods The active components and their targets of Ginkgo biloba were retrieved from databases such as TCMSP,Swiss Target Prediction,PubChem,and GeneCards.Tongue cancer-related genes were obtained from GeneCards,and a PPI network was constructed.GO and KEGG enrichment analyses were performed,and molecular docking was used for validation.In vitro,the viability of tongue cancer cells(Tca-8113)was detected by CCK-8 assay,and apoptosis-related proteins were detected by Western Blot.Results A total of 234 targets of Ginkgo biloba,924 tongue cancer genes,and 81 common targets between the disease and the drug were identified.The core targets included BCL2,PTGS2,MMP9,AKT1,etc.The biological process(BP)enrichment results showed that the targets were related to the Ephrin receptor signaling pathway,one-carbon metabolism,and epidermal growth factor receptor signaling pathway.The cellular component(CC)enrichment results indicated strong associations with receptor complexes,membrane rafts,and plasma membranes.The molecular function(MF)enrichment results revealed associations with carbonic anhydrase activity,histone H3Y41 kinase activity,histone H2AXY142 kinase activity,and transmembrane receptor protein tyrosine kinase activity.The KEGG pathway enrichment results showed that the targets of Ginkgo biloba against tongue cancer were mainly involved in nitrogen metabolism,the PI3K-Akt signaling pathway,proteoglycans,endocrine resistance,and epidermal growth factor receptor tyrosine kinase inhibitors.The in vitro experimental results showed that the viability of tongue cancer cells decreased with increasing concentrations of Ginkgo biloba extract,and the extract inhibited the expression of Bcl-2 protein and the activation of the p-AKT/AKT signaling pathway.Conclusion Network pharmacology has revealed that Ginkgo biloba exerts its anti-tongue cancer effects through multiple targets and pathways.Cellular experiments have demonstrated that Ginkgo biloba may inhibit the proliferation of tongue cancer cells by downregulating the expression of anti-apoptotic factor Bcl-2 and inhibiting the activation of the PI3K-Akt signaling pathway.

Abstract:Objective To systematically screen differentially expressed microRNAs(miRNAs)in serum of colorectal cancer patients based on high-throughput sequencing technology,construct a multi-miRNA combination diagnostic biomarker,and provide novel molecular markers for early non-invasive diagnosis of colorectal cancer.Methods A case-control study design was adopted,including 30 patients with colorectal cancer and 20 healthy controls.High-throughput small RNA sequencing was performed using the Illumina HiSeq 2500 platform to screen for differentially expressed miRNAs(log2 Fold Change,|log2FC|≥1,P＜0.05).Target genes were predicted using miRanda and RNAhybrid algorithms,and Gene Ontology(GO)functional enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analyses were conducted using the DAVID platform.Receiver operating characteristic(ROC)curve analysis and logistic regression methods were employed to construct the optimal miRNA combination diagnostic model.Results High-throughput sequencing identified a total of 205 differentially expressed miRNAs,including 98 upregulated and 107 downregulated.Functional enrichment analysis revealed that differential miRNAs were mainly enriched in tumor-related biological processes such as Notch signaling pathway(P＜0.01),autophagy-related pathways(P＜0.05),and transmembrane receptor protein tyrosine kinase signaling pathway(P＜0.001).A 5-miRNA combination diagnostic biomarker consisting of miR-21-5p,miR-92a-3p,miR-155-5p,miR-143-3p,and miR-145-5p was successfully constructed,with an area under the ROC curve of 0.924(95%CI:0.867-0.981),diagnostic sensitivity of 90.00%,and specificity of 85.00%,significantly superior to traditional serum tumor markers CEA(AUC=0.663)and CA19-9(AUC=0.598).This biomarker also demonstrated excellent diagnostic efficacy for early-stage colorectal cancer(stage Ⅰ-Ⅱ)(AUC=0.895).Conclusion The 5-miRNA serum combination biomarker screened based on high-throughput sequencing has excellent diagnostic efficacy for colorectal cancer,especially suitable for early non-invasive screening,providing a new molecular tool for the precise diagnosis and clinical decision-making of colorectal cancer.

Abstract:Objective To explore the correlations between the key characteristics of the tooth extraction socket(shape,healing time,root tip depth)and the selection of implant shape as well as the implant torque,in order to provide evidence-based medical evidence for personalized implant treatment plans.Methods A retrospective study design was adopted,and 132 cases of single tooth extraction followed by implant restoration were included.The shape and root apex depth of the extraction socket were precisely measured using CBCT,and the shape of the implant and the actual implant torque data were extracted from the surgical records.Variance analysis,chi-square test,and multiple linear regression models were used to systematically analyze the association strength and statistical significance between the characteristics of the extraction socket and the selection of implant shape as well as the implant torque.Results The proportion of choosing conical implants for irregular-shaped extraction sockets(68.20%)was significantly higher than that for circular extraction sockets(23.50%);the implant torque in the delayed implant group(3 months or more after extraction)was(21.3±3.5)(N·cm),which was significantly higher than that in the immediate implant group(12.6±2.8)(N·cm);multivariate linear regression analysis showed that for every 1 mm increase in root apex depth,the average implant torque increased by 1.2(N·cm).Conclusion The shape of the extraction socket,the healing time,and the root tip depth are the core key factors influencing the selection of implant shape and the implant torque.Among them,the irregular-shaped extraction socket is more suitable for conical implants.Extending the healing time and increasing the root tip depth can significantly enhance the implant torque.

Abstract:Objective To explore and evaluate the rehabilitation effect of multidisciplinary team(MDT)intervention based on King's Theory of Goal Attainment in patients with pulmonary embolism(PE).Methods A total of 60 patients with acute pulmonary embolism(APE)were consecutively recruited from the Respiratory Medicine Ward of the First Affiliated Hospital of Jinzhou Medical University between August 2025 and November 2025.A computer-generated random number table was used to allocate these patients into a control group and an observation group in a 1∶1 ratio,with 30 cases in each group.The control group received routine nursing care for respiratory diseases,while the observation group was given an additional multidisciplinary team collaborative nursing intervention based on the King's Theory of Goal Attainment on top of the routine care.Both groups underwent synchronous in-hospital nursing and follow-up management for 4 weeks after discharge.After the intervention,the two groups were compared in terms of chest pain intensity,peak lower extremity venous blood flow velocity,coagulation function parameters,psychological status and quality of life scores.Results After the intervention,the chest pain severity in the observation group was significantly lighter than that in the control group(P＜0.05).After the intervention,the peak velocity of lower extremity venous blood flow,activated partial thromboplastin time(APTT),prothrombin time(PT),and thrombin time(TT)increased in both groups,while the D-dimer(D-D)and fibrinogen(FIB)decreased.In addition,the improvement degree of each index in the observation group was significantly better than that in the control group(P＜0.05).After the intervention,the emotional scores evaluated by the Self-Rating Anxiety Scale(SAS)and Self-Rating Depression Scale(SDS)decreased in both groups,with a greater decrease in the observation group,and the scores were significantly lower than those in the control group(P＜0.05);the scores of all dimensions of quality of life increased in both groups,with a more significant increase in the observation group,and the scores of all dimensions were better than those in the control group(P＜0.05).Conclusion Multidisciplinary team-based nursing intervention integrated with King's Theory of Goal Attainment can significantly alleviate chest pain symptoms,improve coagulation function and hemodynamic indexes,relieve anxiety and depression,and remarkably enhance the quality of life in patients with pulmonary embolism.All outcome indicators demonstrate that this intervention yields superior effects compared with routine nursing care,indicating its suitability for clinical promotion.

Abstract:Objective To investigate the clinical efficacy of sivelestat sodium combined with aexamethasone in the treatment of post-traumatic acute respiratory distress syndrome(ARDS).Methods A total of 80 patients with ARDS at Kaifeng People's Hospital from October 2022 to October 2024 were randomly selected for the study.Using a random number table,the patients were equally assigned to a control group(n=40)and an observation group(n=40).The control group received dexamethasone sodium phosphate injection,while the observation group received a combination of dexamethasone sodium phosphate injection and sivelestat sodium.The following outcomes were compared between the two groups:Murray Lung Injury Score(MLIS),Sequential Organ Failure Assessment(SOFA)score,serum inflammatory markers including procalcitonin(PCT),interleukin-6(IL-6),and C-reactive protein(CRP)levels,oxygenation index(PaO2/FiO2),blood lactic acid(Lac)concentration,carbonic anhydrase(CA)activity,adverse events,as well as clinical recovery and prognosis.Results Some patients in both groups died after treatment.The mortality rate of the observation group was 45.00％,which showed no statistical significance compared with the control group(P＞0.05).The mechanical ventilation time(8.10±2.06)days was significantly lower than that of the control group(P＜0.05).However,the ICU hospitalization time(11.83±2.42)days and the mortality rate of 45.00％showed no statistical significance compared with the control group(P＞0.05).After treatment,the MLIS(5.10±2.16)and SOFA(7.23±2.86)scores in the observation group were significantly lower than those in the control group(P＜0.05).After treatment,the observation group had lower levels of PCT(0.35±0.04)ng/mL,IL-6(121.39±16.37)pg/mL,and CRP(16.26±3.41)mg/L compared to the control group(P＜0.05).The PaO2/FiO2(90.82±10.82)mmHg in the observation group was higher than that in the control group,while Lac(3.59±0.53)mmol/L was lower(P＜0.05).The total incidence of adverse reactions in the observation group(10.00％)was slightly higher than that in the control group(5.00％),but the difference was not statistically significant(P＞0.05).The mechanical ventilation time(8.10±2.06)days in the observation group was significantly shorter than that in the control group(P＜0.05),while there was no statistically significant difference in ICU length of stay(11.83±2.42)days or mortality rate(45.00％)between the two groups(P＞0.05).Conclusion The combination of sivelestat sodium and dexamethasone in the treatment of post-traumatic ARDS significantly improves lung injury scores,reduces serum inflammatory factor levels,increases the oxygenation index,decreases lactate levels,and shortens mechanical ventilation time,demonstrating favorable efficacy.However,limitations remain in terms of ICU length of stay and mortality reduction,necessitating further research to optimize the treatment regimen.

Abstract:Brain insulin resistance is characterized by the weakened effect of insulin in the brain,and is regarded as a common pathological feature of metabolic disorders and neurodegenerative diseases.To explore the causes and pathological mechanisms of brain insulin resistance,we collected and analyzed the literature on brain insulin resistance in the PubMed database from 1946 to 2024.The result shows that apart from a small amount produced by some brain tissues,most of the insulin in the brain enters through the blood-brain barrier under the regulation of receptors;the lack of insulin in the brain due to insulin receptor resistance and reduced permeability of the blood-brain barrier,as well as the reduced insulin sensitivity of brain tissues themselves,are the two main manifestations of brain insulin resistance;the molecular mechanisms regulating the formation of brain insulin resistance involve multiple aspects such as inflammatory factors,oxidative stress,microtubule-associated protein Tau,glycogen synthase kinase 3β,sugar transporters 4,and neurotoxic substances;from a macroscopic perspective,behavioral factors such as high-sugar and high-fat diets,as well as tissue lesions such as fatty liver,aging,and brain trauma,can also lead to the situation of brain insulin resistance.This study systematically explored the formation mechanism,molecular mechanism and main regulatory factors of brain insulin resistance,aiming to provide a theoretical basis for future targeted intervention of brain insulin resistance to address metabolic disorders or related brain function diseases.
