Objective To construct a predictive model for futile recanalization after endovascular treatment in patients with acute anterior circulation large vessel occlusion stroke and evaluate its predictive efficacy.Methods Patients with acute stroke caused by anterior circulation large vessel occlusion who underwent endovascular treatment with successful vascular recanalization(modified thrombolysis in cerebral infarction[mTICI]grade 2b or 3)admitted to the Department of Neurosurgery of Tianjin Union Medical Center(the First Affiliated Hospital of Nankai University)from January 2022 to January 2025 were retrospectively and consecutively included.Patients were divided into effective recanalization group(modified Rankin scale[mRS]score≤2)and futile recanalization group(mRS score>2)according to the mRS score at 90 days after endovascular treatment.Baseline and clinical data were collected,including sex,age,medical history(stroke history,hypertension,diabetes mellitus,atrial fibrillation),personal history(smoking history,alcohol consumption history),and National Institutes of Health stroke scale(NIHSS)score,blood pressure,blood glucose,total cholesterol,triglycerides,high-density lipoprotein cholesterol,low-density lipoprotein cholesterol,creatinine,neutrophil-to-lymphocyte ratio,fibrinogen,D-dimer,lymphocyte-to-monocyte ratio,white blood cell count,hemoglobin,albumin,C-reactive protein-to-albumin ratio,platelet-to-lymphocyte ratio at admission.Imaging data including culprit vessel(middle cerebral artery,anterior cerebral artery,internal carotid artery),Alberta stroke program early CT score(ASPECTS),infarct core volume,hypoperfusion area volume,mismatch volume between infarct core and hypoperfusion area,American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology(ASITN/SIR)collateral circulation grading,trial of Org 10172 in acute stroke treatment(TOAST)classification.Surgery-related data including onset-to-puncture time,successful puncture-to-vascular recanalization time,immediate postoperative mTICI grade,complications within 24 hours postoperatively(fever,hemorrhagic transformation,symptomatic intracranial hemorrhage),immediate postoperative mTICI grade.Factors with P<0.05 and without multicollinearity(variance inflation factor≥5)in univariate analysis were included in multivariate Logistic regression model analysis to analyze independent influencing factors for futile recanalization after endovascular treatment in patients with acute anterior circulation large vessel occlusion stroke.A nomogram prediction model was constructed based on statistically significant factors in multivariate Logistic regression analysis,and Hosmer-Lemeshow test was used to assess the goodness of fit of the model.The receiver operating characteristic(ROC)curve of the nomogram prediction model for predicting futile recanalization after endovascular treatment in patients with anterior circulation large vessel occlusion stroke was drawn,and calibration curve was used to evaluate the calibration of the nomogram prediction model.Results A total of 187 patients who met the criteria of this study were included,comprising 101 males and 86 females,aged 42-85 years,with a mean age of(70±6)years.The mRS scores at 90days after treatment were:0points in 21 cases(11.23%),1 point in 37 cases(19.79%),2 points in 28 cases(14.97%),3 points in 46 cases(24.60%),4 points in 31 cases(16.58%),5 points in 24 cases(12.83%),and 6 points in 0case.There were 86cases in the effective recanalization group and 101 cases in the futile recanalization group.(1)Statistically significant differences between the two groups were observed in age,atrial fibrillation,infarct core volume,admission NIHSS score,neutrophil-to-lymphocyte ratio,lymphocyte-to-monocyte ratio,and C-reactive protein-to-albumin ratio(all P<0.05).(2)Multicollinearity analysis showed that the variance inflation factors of all independent variables with statistically significant differences in univariate analysis were all<5,indicating no multicollinearity.Multivariate Logistic regression analysis showed that age(OR,1.101,95%CI 1.046-1.158,P=0.037),infarct core volume(OR,1.350,95%CI 1.202-1.517,P<0.01),admission NIHSS score(OR,1.501,95%CI 1.213-1.858,P<0.01),lymphocyte-to-monocyte ratio(OR,0.039,95%CI 0.009-0.179,P<0.01),and C-reactive protein-to-albumin ratio(OR,6.015,95%CI 1.625-22.257,P=0.007)were independent influencing factors for futile recanalization after endovascular treatment in patients with acute anterior circulation large vessel occlusion stroke.(3)The receiver operating characteristic curve of the nomogram prediction model for futile recanalization after endovascular treatment in patients with acute anterior circulation large vessel occlusion stroke was constructed based on statistically significant factors in multivariate analysis showed a specificity of 0.970,sensitivity of 0.895,precision of 0.916,recall of 0.970,and area under the curve of 0.979(95%CI0.962-0.996,P<0.01).The absolute mean error of the calibration curve was 0.008,with predicted values close to actual values.Hosmer-Lemeshow test results showed that the model had good consistency without overfitting(χ2=4.830,P=0.776).Conclusions Age,infarct core volume,admission NIHSS score,lymphocyte-to-monocyte ratio,and C-reactive protein-to-albumin ratio are all independent influencing factors for futile recanalization after endovascular treatment in acute anterior circulation large vessel occlusion stroke.The nomogram prediction model constructed accordingly can predict the risk of futile recanalization after endovascular treatment in patients with anterior circulation large vessel occlusion stroke.

BACKGROUND:Studies have shown that vascular factors have an important impact on the occurrence of diabetic foot.OBJECTIVE:To investigate the important role of angiopoietin-like protein 4 in the formation of diabetic foot.METHODS:(1)Bioinformatics analysis was performed on the gene expression profile data of diabetic foot patients to find the key genes.The skin samples of diabetic foot patients and healthy people were collected for hematoxylin-eosin staining,immunohistochemical staining,and qRT-PCR experiments to detect the expression of angiopoietin-like protein 4.(2)The immortalized human skin fibroblast cell line and primary human umbilical vein endothelial cells were cultured.The two kinds of cells were divided into control group and exogenous angiopoietin-like protein 4 supplemented group.The migration ability and proliferation ability of fibroblasts were detected by scratch assay and CCK-8 assay.The proliferation ability of endothelial cells was detected by Ki67 assay.RESULTS AND CONCLUSION:(1)Bioinformatics analysis results showed that the down-regulation of angiopoietin-like protein 4 gene might be the key gene leading to the formation of diabetic foot.(2)Hematoxylin-eosin staining exhibited that compared with normal skin,angiopoietin-like protein 4 was weakly expressed in diabetic foot skin,and the mRNA level was decreased(P<0.01).(3)Scratch assay results demonstrated that compared with the control group,fibroblast migration ability was significantly enhanced in the angiopoietin-like protein 4 group.CCK-8 assay showed that the absorbance value of fibroblasts in the angiopoietin-like protein 4 group was higher than that of the control group at 24 and 48 hours(P<0.01,P<0.001).It is suggested that angiopoietin-like protein 4 can enhance the migration and proliferation of fibroblasts.(4)Ki67 assay results demonstrated that the number of Ki67 positive cells in the angiopoietin-like protein 4 group was significantly more than that in the control group.CCK-8 assay results showed that the absorbance value of endothelial cells in the angiopoietin-like protein 4 group was higher than that of the control group at 24 and 48 hours(P<0.05,P<0.001).(5)All findings suggest that angiopoietin-like protein 4 can enhance the proliferation of endothelial cells treated with high glucose.
