Clinical values of serum visfatin and thrombus precursor protein in the diagnosis of lacunar infarction / 中国基层医药

ABSTRACT

Objective To explore the changes of serum visfatin and thrombus precursor protein (TpP) levels in patients with lacunar infarction,and the relationship with carotid atherosclerotic plaque ,and to determine the values of the two factors to predict lacunar infarction .Methods Carotid atherosclerosis plaques were detected in 95 cases with lacunar infarction,including 56 cases in unstable plaque group,39 cases in stable plaque group,and another 70 healthy persons were selected as control group .Serum visfatin,high-sensitivity C reactive protein (hs-CRP), interleukin-6(IL-6) and TpP levels were measured.The carotid atherosclerotic plaque was examined by color Doppler ultrasonography.Results The levels of visfatin,hs-CRP and IL-6 in the unstable plaque group and stable plaque group were higher than those in the control group (t =10.886,9.180,11.889,4.990,5.084,9.703,all P <0.05).The levels of visfatin,hs-CRP and IL-6 in the unstable plaque group were (29.10 ±8.85)μg/L,(6.15 ± 2.78)mg/L and (5.98 ±2.66) pg /mL,respectively, which were higher than those in the stable plaque group [(21.47 ±8.39)μg/L,(4.37 ±2.09)mg/L and (4.64 ±2.03)pg/mL,t =4.222,3.385,2.652,all P <0.05]. Pearson linear correlation analysis and multiple linear stepwise regression analysis showed that serum visfatin levels were positively correlated with hs-CRP and IL-6.The TpP levels of 3h,6h and 12h after cerebral infarction in the unstable plaque group and stable plaque group were higher than those in the control group (t =17.342,21.770, 18.138,11.228,15.245,14.306,all P <0.05).The TpP levels of 3h,6h and 12h after cerebral infarction in the unstable plaque group were (18.52 ±6.43)mg/L,(25.95 ±7.98)mg/L,(18.43 ±6.10)mg/L,respectively,which were higher than those in the stable plaque group [(12.40 ±5.37) mg/L,(20.81 ±8.60) mg/L, (13.86 ± 5.04)mg/L,t =3.282,2.991,3.850,all P <0.05].Conclusion The serum levels of visfatin and TpP are highly specific,can be used as important indicators for prediction and diagnosis of lacunar infarction ,and they are related to the stability of carotid atherosclerotic plaque .
