RESUMEN
Objective To study the changes of plasma biomolecules in patients with acute cerebral infarction(ACI) and the potential influences from lumbrukinase and aspirin(ASA). Methods Seventy patients with ACI were randomly divided into three groups according to the ways of administration: lumbrukinase group(n=26),ASA group(n=24)and lumbrukinase + ASA group(n=20).Plasma levels of P-selectin,D-dimer(D-D),tissue plasminogen activator(t-PA),plasminogen activator inhibitor-1(PAI-1),plasmin-antiplasmin complex(PAP),thrombin-antithrombin complex(TAT),homocysteine(Hcy) and thrombin-activatable fibrinolysis inhibitor(TAFI) were measured in these patients with ACI and normal individuals(n=20) by ELISA method.Changes of these parameters were detected before and after the treatment,and the diagnostic efficiencies for ACI were compared by receiver characteristic curve(ROC).Results Before the treatment,all the parameters in patients with ACI were significantly higher than those in the healthy controls(P0.05).However,there were significant changes of PAP in the lumbrukinase group(P
