Background: There exists brain tissue inflammation and endothelial function damage in stroke. Method: We investigated serum and cerebrospinal fluid (CSF) levels of PTX3, HSP70, VEGF, IL-6, CRP in patients with stroke, this study was conducted on 85 standard stroke patients during 2015-2016, include ischemic stroke (IS) group (52 cases) and hemorrhagic stroke (HS) group (33 cases). The patients without inflammatory and neurological disease were the control group (20 cases). The levels of PTX3, HSP70, VEGF, IL-6 and CRP in serum on the 1th, 5th and 14th day after admission were measured and compared them with that in cerebrospinal fluid, NIHSS and Barthel score were also performed for assessing patients with HS. The results showed that the serum levels of PTX3, HSP70, VEGF, IL-6, CRP with HS were higher than that with IS patients (P<0.001, P=0.16, P=0.08, P=0.12, P<0.001, respectively), and PTX3 level began to fall after 14th day (P=0.015). The cerebrospinal fluid of PTX3, HSP70,VEGF and IL-6 levels in patients with HS were higher than that of normal control group (P=0.002, P=0.003, P<0.001, P<0.001, respectively). The levels of PTX, HSP70, IL-6 in cerebrospinal fluid were higher than that in the serum (P=0.026, P<0.001, P<0.001, respectively), and VEGF, CRP instead (P=0.011, P<0.001, respectively). The level of PTX3 in cerebrospinal fluid was positively correlated with IL-6 in patients with HS (P<0.001), PTX3 and IL-6 in patients with HS were positively correlated with patients' NIHSS score (P=0.007, P<0.001, respectively), and negatively correlated with Barthel index score (P=0.023, P<0.001, respectively). Inflammation and endothelial damage were more severe in patients with HS. The levels of PTX3 and IL-6 in cerebrospinal fluid could assess the severity, progression, and prognosis of HS. PTX3 may be a potential biomarker in HS, it could provide potent basis for doctors to select appropriate treatment measures as soon as possible.
