title: [Relationship between cystatin C and cerebral infarction].
abstract: OBJECTIVE
  To study the relationship between cystatin C and cerebral infarction and explore the role of cystatin C in the protection against cerebral infarction.
  
  
  METHODS
  Eighty-three patients with cerebral infarction and 71 randomly selected age- and gender-matched patients in the Department of Neurology (control group) were enrolled in this study. Fasting whole blood (3 ml) was obtained from the patients in both groups and the sera were separated to determine the levels of cystatin C using particle reinforced immunoturbidimetric assay.
  
  
  RESULTS
  The serum cystatin C level was significantly lower in the cerebral infarction group than in the control group (1.62-/+0.31 vs 2.23-/+0.22 mg/L, P<0.01).
  
  
  CONCLUSIONS
  Cystatin C is closely related to cerebral infarction probably as a protective factor against cerebral infarction.
