ABSTRACT
Objective To investigate the relationship between the level of 8-iso-prostaglandin (8-iso-PG)F2αand the neural functional deficit in patients with acute cerebral infarction (ACI). Methods Sixty-seven ACI patients were se-lected in Neurological Department of Ganyu People’s Hospital. According to the age, these subjects were divided into two groups:the old group (≥60 years, n=37) and middle-young group (<60 years, n=30). Thirty healthy subjects were selected as controls (≥60 years). The age, gender and anamnesis were matched in two groups of elderly people. The ELISA was used to detect the plasma levels of 8-iso-PGF2αin two groups of patients. And NIHSS score was used to evaluate the severity of clinical neurological deficit. Results The plasma levels of 8-iso-PGF2α were significantly higher in old ACI group (506.38±138.63) ng/L than those of middle-young ACI group (420.18±132.72) ng/L and old control group (369.98±99.81) ng/L. There was no significant difference in plasma level of 8-iso-PGF2αbetween middle-young ACI group and old control group (F=9.272,P<0.05). The NIHSS score was significantly higher in old group (19.78±3.66) than that of middle-young group (17.73 ± 2.70, t=2.539,P<0.05). There was a positive correlation between plasma 8-iso-PGF2α level and NIHSS score in old group (r=0.504,P=0.001). Conclusion The oxidative stress plays an important role in the occurrence and de-velopment process of ACI in elderly patients. The earlier and reasonable antioxidant therapy plays a positive role to alleviate the clinical symptoms and promote the recovery of illness.
ABSTRACT
Objective To study the early changes of the coagulation system in type 2 diabetic nephropathy.Methods Sixty-two cases of patients with type 2 diabetic nephropathy were divided into two groups:normal albuminuria group ( N-UAlb group,UACR ＜ 30 mg/g,32 cases ),microalbuminuria group ( MUAlb group,UACR:30～300 mg/g,30 cases).Thirty healthy persons constituted a control group (NC group).Fibrinogen( FIB ),antithrombin Ⅲ ( AT-Ⅲ ),protein C ( PC ),protein S ( PS ) were measured by coagulation analyzer,while yon willebrand factor (vWF) and platelet granule membrane protein 140 (GMP-140) were detected by ELISA assay,platelet count (PLT),mean platelet volume(MPV),platelet hematocrit (PCT),platelet distribution width(PDW) by hematology analyzer.Results The level of fibrinogen,GMP-140 and vWF in the M-UAlb group were (4.20 ± 1.53 ) g/L,( 30.03 ± 7.77 ) μg/L,and ( 315.53 ± 47.24 ) ％ respectively,vwhich were significantly higher than those in the N-UAlb group [ ( 3.21 ± 0.89 ) g/L,( 18.22 ± 5.08 ) μg,/L and ( 191.88 ± 57.25 ) ％ respectively ] and the NC group [ ( 2.75 ± 0.53 ) g/L,( 14.26 ± 2.29 ) μg/L and ( 138.12 ± 61.27 ) ％ respectively ] ( F =5.42,10.42,30.44,P ＜ 0.05 or 0.01 ).The fibrinogen,vWF,GMP-140 were positively correlated with UACR ( r =0.313,P ＜ 0.05 ; r =0.620,P ＜ 0.01 ; r =0.680,P ＜ 0.01 ) and PC was negatively correlated with UACR ( r =-0.255,P ＜ 0.05 ).Conclusion Hypercoagulable state in diabetic nephropathy is associated with the high fibrinogen,endothelial dysfunction and platelet activation,and these changes have already emerged in patients without albuminuria.This might mind us that we should strengthen anticoagulant therapy on patients when they are not progressing to albuminuria.
