Diagnostic value of plasma PPARγ level in hemorrhagic transformation in patients with non thrombolytic acute cerebral infarction / 中风与神经疾病杂志

ABSTRACT

@#ObjectiveTo investigate the value of peroxisome proliferator-activated receptor γ（PPARγ）level in predicting hemorrhagic transformation in patients with non thrombolytic acute cerebral infarction. MethodsA total of 92 patients with non thrombolytic acute cerebral infarction who were treated in our hospital from May 2017 to May 2020 were selected as the research objects，and they were divided into hemorrhagic transformation group（n=14）and non hemorrhagic transformation group（n=78）according to the occurrence of hemorrhagic transformation. The plasma levels of PPARγ and fibronectin（FN）were detected by enzyme-linked immunosorbent assay（ELISA）；the correlation between plasma PPAR-γand blood lipid levels in patients with hemorrhagic transformation of non thrombolytic acute cerebral infarction was analyzed；the predictive value of plasma PPARγ and FN levels on hemorrhagic transformation in patients with non thrombolytic acute cerebral infarction was analyzed；the influencing factors of hemorrhagic transformation in patients with non thrombolytic acute cerebral infarction were analyzed. ResultsThe levels of PPARγ and FN were higher than those in non hemorrhagic transformation group，The area under the curve（AUC）of plasma PPARγ and FN levels in predicting hemorrhagic transformation in patients with non thrombolytic acute cerebral infarction was 0.933 and 0.860，respectively，the specificity was 89.7% and 78.2%，and sensitivity was 85.7% and 78.6%，respectively；the AUC of the combined prediction was 0.952，the specificity was 89.7%，and the sensitivity was 92.9%. PPARγ was an independent risk factor for hemorrhagic transformation in patients with non thrombolytic acute cerebral infarction（P<0.05）. ConclusionPlasma PPARγ is a factor influencing hemorrhagic transformation in patients with non thrombolytic acute cerebral infarction，which may have important predictive value for secondary hemorrhagic transformation.
