Relationship Between Acute Cerebral Infarction and Serum Inflammatory Cytokines / 沈阳医学院学报

ABSTRACT

Objective:To investigate the changes of serum inflammatory cytokines in patients with acute cerebral infarction (ACI) and its clinical significance by detecting the serum levels of homocysteine (Hcy),cystatin C (Cys C),high-sensitivity C-reactive protein (hs-CRP) . Methods:A total of 82 ACI patients (ACI group) and 50 healthy persons (control group) were selected,the serum Hcy,Cys C,hs-CRP levels of all subjects were determined,the relationship between inflammatory cytokines and USA National Institutes of Health Stroke Scale (NIHSS) was analyzed. Finally,the roles of inflammatory cytokines in diagnosis of ACI were evaluated. Results:The levels of Hcy,Cys-C and hs-CRP in ACI group were significantly higher than those in control group (P<0.01) . The serum levels of these factors had significant difference among different neurological deficiency groups (P<0.05), and had a positive correlation with NIHSS score (r=0.396, 0.445, 0.391, P<0.01), hs-CRP had the highest sensitivity (72.0%) and specificity (82.0%) for diagnosis of ACI. Conclusions:The hs-CRP, Hcy and Cys C play important roles in the onset and development of ACI and can reflect the severity of ACI. Among them,Hcy is the important dangerous factor of ACI,the level of Cys C reflectes the degree of the vascular inflammatory injury,and hs-CRP can be used as an index to diagnose and evaluate the severity of ACI.
