Study on the relationship between restenosis and endothelial function after interventional surgery for diabetic lower extremity arteriopathy
Objective To explore the relationship between postoperative restenosis and vascular endothelial function in patients with lower extremity arterial disease(LEAD).Methods A retrospective analysis was performed on 133 patients with diabetic lower extremity arteriopathy who had successfully undergone interventional therapy in our hospital,and the patients were followed up for one year,and the patients were grouped according to whether restenosis occurred,with 25 cases in the restenosis group and 108 cases in the non-stenosis group.The patient's vascular endothelial function index,inflammatory factor level,blood lipid four items and hemoglobin A1c(HbAlc)were detected,and peripheral blood cells of patients in the stenosis group and non-stenosis group were isolated for transcriptome sequencing.Multivariate unconditional logistic regression analysis was used to screen for independent risk factors for vascular endothelial function in postoperative restenosis.Results Serum endothelin-1(ET-1),von Willebrand factor(vWF),thromboxane B2(TXB2),vascular cell adhesion protein 1(VCAM-1),and nitric oxide(NO)were significantly higher in the stenosis group than in the non-stenosis group,while endothelial nitric oxide synthase(eNOS)and vascular endothelial growth factor(VEGF)were significantly lower than those in the non-stenosis group(P<0.01).There was no significant difference in blood lipids between the two groups(P>0.05).The HbAlc of the stenosis group was significantly higher than that of the non-stenosis group(P<0.01).The inflammatory factors in the stenosis group were significantly higher than those in the non-stenosis group(P<0.05).Transcriptome sequencing analysis results are consistent with test results.Multivariate Logistic regression analysis showed that TNF-α,IL-6,ET-1,and vWF were independent risk factors for LEAD vascular restenosis(P<0.05).Conclusion Vascular endothelial function indexes(ET-1,vWF)and inflammatory factors(TNF-α,IL-6)are independent risk factors for restenosis after interventional surgery.
