Abstract:
Objective To investigate the level of vascular endothelial growth factor (VEGF), homocysteine (HCY), fibronectin (Fn) and apolipoprotein E (ApoE) in the serum and cerebrospinal fluid patients with stroke to inquire into patients′endothelial function damage.Methods We chose standard stroke patients in Brain Hospital of Hu′nan Province from August 2015 to August 2016, divided into ischemic stroke (IS) group (52 cases) and hemorrhagic stroke (HS) group (33 cases), and chose patients with the cerebrospinal fluid for diagnosis and treatment and ruled out infections, the nervous system and cardiovascular system diseases as control group (20 cases).The serum VEGF, HCY, Fn, and ApoE levels of the patients on the 1 th, 5 th and14 th day after admission were monitored and compared with those in cerebrospinal fluid expression, NIHSS and Barthel were also performed for assessment of severity and prognosis of HS.Results The serum levels of VEGF, HCY and ApoE in HS group were higher than those in IS group, and the Fn level was lower than that in IS group and control group.At the same time, the Fn levels gradually increased on the 5 th and 14 th day after admission (P＜0.05), close to the control group.Cerebrospinal fluid of VEGF, HCY, Fn, and ApoE levels in HS group were higher than those in the control group, while Fn level was lower, and these indexes were lower in cerebrospinal fluid than those in the serum, and the differences were statistically significant (P＜0.05).In correlation analysis, HCY level of cerebrospinal fluid was positively correlated with ApoE in HS patients (r=0.645, P=0.001), HCY and ApoE levels in HS patients were positively correlated with patients′NIHSS score (r=0.547, P=0.006;r=0.720, P＜0.001), and negatively correlated with Barthel index score (r=-0.703, P＜0.001, r=-0.765, P＜0.001, respectively).Conclusion There were vascular endothelial injury and neuroprotective function decreased in brain tissue of stroke patients.The level of Fn was related to the patient′s prognosis, which was conducive to the differentiation of IS and HS.The cerebrospinal fluid levels of HCY and ApoE can be used to evaluate the prognosis of HS patients.
