ABSTRACT
Objective To explore the correlation between the serum levels of fibrinogen (FIB), C-reactive protein (CRP) and homocysteine (Hcy) with the carotid vulnerable plaque in patients with large artery atherosclerosis (LAA) stroke.Methods The patients with acute ischemic stroke (AIS) admitted to the Department of Neurology in The Second Hospital of Lanzhou University from Mar. 2014 to Feb. 2015 were collected continuously, and 273 patients with anterior circulation of LAA stroke were selected based on the TOAST classification. These patients were classified as non-plaque group (n=84), stable plaque group (n=42) and vulnerable plaque group (n=147) according to the carotid ultrasonography examination. Another 182 patients without carotid disease of non-stroke selected simultaneously from our department were regarded as controls. The 19 demographic parameters and hematological indices were compared among the four groups. The logistic regression was used to screen the independent risk factors for carotid vulnerable plaque in LAA stroke patients. The Spearman rank correlation was performed to analyze the correlation between the carotid plaque vulnerability in LAA stroke patients with all the indicators.Results The levels of FIB, CRP and Hcy in the four groups showed statistically signicantcant differences (P<0.05). The multivariate logistic regression analysis revealed that FIB (OR=1.408, 95% CI 1.028-1.927,P=0.033) was the independent risk factor for carotid vulnerable plaque in patients with LAA stroke. The Spearman correlation analysis presented a positive correlation between carotid plaque vulnerability in LAA stroke patients with FIB (r=0.292;P=0.000) and Hcy (r=0.172;P=0.000). Conclusions The serum FIB and Hcy levels may be the meaningful biomarkers to predict the vulnerable carotid plaque in patients with LAA stroke. The serum level of CRP has no obvious correlation with carotid plaque vulnerability in LAA stroke patients.
ABSTRACT
Objective To investigate the risk factors of recurrent ischemic stroke, and evaluate the severity and short-term outcome. Methods From March, 2014 to March, 2015, 238 patients with recurrent ischemic stroke and 378 patients with initial ischemic stroke matched with gender and age were enrolled. The clinical data of two groups were compared and the non-conditional Logistic regression model was made to analysis the risk factors of recurrent ischemic stroke. The National Institute of Health Stroke Scale (NIHSS) score as ad-mission and discharge, and the neural function improvement rate of two groups were compared. Results The incidences of leukoarailsis (χ2=8.666), hypertension (χ2=8.189), smoking (χ2=6.973) and alcohol consumption (χ2=4.722) were higher in the recurrent group than in the pri-mary group (P<0.05). Logistic regression analysis showed that leukoarailsis (OR=1.690, 95%CI:1.198~2.384, P=0.003), hypertension (OR=1.715, 95%CI:1.135~2.592, P=0.010) and smoking (OR=1.896, 95%CI:1.233~2.915, P=0.004) were the independent risk factors of recur-rent ischemic stroke. The NIHSS scores as admission and discharge were significantly higher (t=-3.645, t=-4.675, P<0.001), and the neural function improvement rate was lower (t=2.643, P<0.01) in the recurrent group than in the primary group. Conclusion Hypertension, leuko-arailsis and smoking are independent risk factors for recurrent ischemic stroke. Recurrent ischemic stroke is more serious than initial isch-emic stroke, and the short-term neural function recovers more slowly.
ABSTRACT
@#Bilirubin is the final product of aging red blood cells when they were destroyed and degraded. Recent studies have demonstrated that it is a kind of endogenous antioxidant, which plays an important role in anti-atherosclerosis, scavenging free radicals and protecting the tissues and organs from damage. More and more studies have focused on the correlation between bilirubin and ischemic stroke. This article summarized the relationship between the antioxidant system of bilirubin and the occurrence, development and prognosis of atherosclerosis and ischemic stroke.

ABSTRACT
Objective To investigate the relationship of the serum bilirubin level with acute ischemic stroke (AIS), and Chinese isch-emic stroke subclassification (CISS), stroke severity and short-term outcome of AIS patients. Methods 616 patients with AIS as well as 664 patients without stroke matched with gender and age were compared and analyzed with the non-conditional Logistic regression. The AIS pa-tients were divided based on the CISS, and their bilirubin levels were compared. The AIS patients were divided into high bilirubin group and normal bilirubin group, their scores of the National Institute of Health Stroke Scale (NIHSS) as admission and discharge, and neural func-tion improvement rate were compared. Results The levels of total bilirubin (TBIL), direct bilirubin (DBIL) and indirect bilirubin (IBIL) were higher in the AIS group than in the control group (P0.05). The NIHSS score was higher in the high bilirubin group than in the normal bilirubin group as admission (P0.05), nor the rate of neural function improvement (P>0.05). Conclusion The serum bilirubin level elevated and correlated with the severity in the AIS patients, which might be the risk of pathogenesis and AIS. The bilirubin was not various with the CISS, and might be less involved in the short-term outcome of AIS.
