ABSTRACT
Objective:To explore relationship among severity of cerebral infarction (CI) ,arteriosclerosis and serum level of cystatin C (CysC) in young and middle‐aged patients with atherosclerotic cerebral infarction (ACI) .Methods:A total of 82 young and middle‐aged ACI patients treated in our hospital from Feb 2013 to Sep 2015 were enrolled .According to CI volume ,they were divided into small infarction group (n=36 ) , medium infarction group (n=22 ) and large infarction group (n=24);according to CI severity ,they were divided into mild CI group (n=54) and severe CI group (n=28);ac‐cording to atherosclerotic plaque nature ,they were divided into stable plaque group (n=45) and unstable plaque group (n=37) .Another 46 healthy people were regarded as healthy control group .Serum CysC level during emergency period and recovery period and carotid intima‐media thickness (IMT) were measured and compared among all groups .Results:Com‐pared with emergency period ,there was significant reduction in serum CysC level in all subgroups of ACI during recovery period , P<0. 01 all;compared with healthy control group ,there were significant rise in serum CysC level [recovery peri‐od:(0.81 ± 0.24) mg/L vs .(1.03 ± 0.13) mg/L vs .(1.09 ± 0.19) mg/L vs .(1.18 ± 0.10) mg/L] during emergency period and recovery period in small ,medium and large infarction group ,and that of large infarction group was significantly higher than those of small and medium infarction group (P<0.01 all) .Compared with healthy control group ,there was significant rise in serum CysC level [recovery period:(0.81 ± 0.24)mg/L vs .(1.07 ± 0.15)mg/L vs .(1.19 ± 0.16)mg/L] during emergency period and recovery period in mild and severe infarction group ,and that of severe infarction group was significantly higher than that of mild infarction group ,P<0.01 all .Compared with healthy control group ,there were sig‐nificant rise in serum CysC level[(0.81 ± 0.24)mg/L vs .(1.18 ± 0.15)mg/L vs .(1.39 ± 0.27)mg/L]during emergency pe‐riod and IMT [(0.72 ± 0.10) mm vs .(1.24 ± 0.17) mm vs .(1.30 ± 0.14) mm]in stable plaque group and unstable plaque group ,and those of unstable plaque group were significantly higher than those of stable plaque group ,P<0. 01 all .Conclu‐sion:The serum CysC level significantly rises in ACI patients ,it can be used as an index for ACI prevention and treatment .
ABSTRACT
Objective:To explore the correlation among serum levels of resistin ,oxidized low density lipoprotein (ox‐LDL) ,high sensitive C reactive protein (hsCRP) and severity of acute ischemic cerebrovascular diseases .Methods :A total of 92 patients with acute ischemic cerebrovascular diseases ,who were treated in our hospital from Nov 2013 to Nov 2014 ,were selected ,including 36 cases with transient ischemic attack (TIA ,TIA group) ,29 cases with re‐versible ischemic brain damage (RIBD ,RIBD group) and 27 cases with focal cerebral infarction (FCI ,FCI group) . Another 70 healthy volunteers were regarded as normal control group .Serum levels of resistin ,ox‐LDL and hsCRP were measured and compared among all groups .Pearson correlation analysis was used to analyze the correlation a‐mong serum levels of resistin , ox‐LDL , hsCRP and severity of acute ischemic cerebrovascular diseases . Results:Compared with normal control group ,there were significant rise in serum levels of resistin [ (0.26 ± 0.42)μg/L vs . (0.63 ± 0.38)μg/L vs .(0.91 ± 0.45)μg/L ,(0.89 ± 0.42)μg/L] ,ox‐LDL [ (334.3 ± 142.5) mg/L vs .(451.7 ± 15.8) mg/L vs .(518.3 ± 205.7) mg/L ,(520.7 ± 198.9) mg/L] and hsCRP [ (5.8 ± 4.9) mg/L vs .(8.7 ± 7.6) mg/L vs .(13.5± 9.1) mg/L ,(13.6 ± 7.4) mg/L] in TIA group ,RIBD group and FCI group (P0.05 all) .Pearson correlation analysis in‐dicated that serum levels of resistin , ox‐LDL and hsCRP were significant positively correlated with severity of acute ischemic cerebovascular disease (r=0.473~0.902 , P<0.01 all) .Conclusion:Serum levels of resistin ,ox‐LDL and hsCRP can reflect severity of acute ischemic cerebrovascular diseases ,which is worth extending .
