To study the relationship between the levels of human angiopoietin like protein 4 (ANGPTL4) and vascular endothelial cell cadherin (VE cadherin) in serum and carotid plaque in patients with acute cerebral infarction. Methods120 patients with acute cerebral infarction were selected as the observation group, and 120 healthy volunteers who underwent physical examination in our hospital were selected as the control group. The ANGPTL4 and VE-cadherin levels in the observation group, the control group and patients with different plaque stability were compared, and the relationship between serum ANGPTL4 and VE-cadherin levels and carotid vulnerable plaque in patients with acute cerebral infarction was studied. ResultsThe level of ANGPTL4 in the observation group was lower than that in the control group, and the level of VE-cadherin was higher than that in the control group (P<0.05); The level of ANGPTL4 in plaque unstable group was lower than that in plaque stable group, and the level of VE-cadherin was higher than that in plaque stable group (P<0.05); The intimal thickness and plaque area of patients in plaque unstable group were higher than those in plaque stable group (P<0.05); Through correlation analysis, ANGPTL4 was negatively correlated with intimal thickness and plaque area, and VE-cadherin was positively correlated with intimal thickness and plaque area (P<0.05). ConclusionThe levels of serum ANGPTL4 and VE-cadherin are significantly correlated with vulnerable carotid plaque in patients with acute cerebral infarction, which can be used as important targets for clinical treatment.
