Abstract:
Objective To investigate the correlation of matrix metallopeptidase-9 (MMP-9 )and tissue inhibitor of metalloprotei-nase-1(TIMP-1)with hemorrheology in male patients with diabetic cerebral infarction.Methods 56 patients with type 2 diabetic cerebral infarction(group A),49 cases with non-diabetic cerebral infarction(group B),and 40 cases of community healthy men (group C)were enrolled in the study.The serum levels of MMP-9 and TIMP-1 and hemorrheology indexes were detected.Results The levels of MMP-9 and MMP-9/TIMP-1 in group A were significantly higher than those in group B and C(P<0.05),however, TIMP-1 level in group A was significantly lower than that of group C(P<0.05).The levels of MMP-9 and MMP-9/TIMP-1 in group B existed significant increasing,compared with group C(P<0.05).The levels of high shear viscosity,plasma viscosity,and platelet aggregation index in group A were significantly higher than those in group B and C(P<0.05).While the levels of low shear viscosity,plasma specific viscosity,and platelet aggregation index showed significant differences between group B and C(P<0.05). MMP-9 positively correlated with high shear viscosity,plasma specific viscosity,and platelet aggregation index(P<0.05).TIMP-1 negatively correlated with high shear viscosity and plasma ratio viscosity(P<0.05).And MMP-9/TIMP-1 showed significant cor-relation with high shear viscosity,low shear viscosity,plasma specific viscosity,and platelet aggregation index(P<0.05).Conclusion In patients with diabetic cerebral infarction,MMP-9,TIMP-1 and their ratio show some correlation with hemorrheology indexes. Detecting these indexes would be helpful for the diagnosis of diabetic cerebral infarction.
