Objective To examine the recurrent ischemic stroke(RIS)in hospitalized patients predicted by Essen Stroke Risk Score(ESRS)and investigate the effect of intensive antiplatelet therapy in patients with high risk of RIS. Methods Retrospective analysis of patients with acute noncardioembolic ischemic stroke consecutively admitted to Peking Union Medical College Hospital(PUMCH)during 2001-2008. All 1008 patients were included in this study, 377 hospitalized in 2001-2002, 315 in 2005 and 316 in 2008. High risk of RIS was defined as ESRS ≥3. The average ESRS score in three groups and percentage of patients with high risk of RIS in each group were calculated. Risk of RIS was evaluated by comparing the average ESRS score in these three groups. Patients with high risk and taking clopidogrel treatment were also evaluated. Results Average ESRS score was 2. 67 ± 1.47,3.55 ± 1.40 and 3.93 ± 1.48(F= 150. 85,P=0.000)in groups of patients hospitalized in 2001-2002, 2005 and 2008 respectively. A significant difference was shown in percentage of high risk patients with ESRS ≥3 in three groups: as 51.64% in 2001-2002,77. 19% in 2005 and 85. 45% in 2008(X2=98.30,P=0. 000),showing a trend of increasing risk of RIS. Except for patients age, rates of having the risk factors in patients increased significantly, including hypertension, diabetes, myocardial infarction, myocardial diseases, smoking,vascular disease and stroke history. Clopidogrel usage has been increasing to 25.63% in 2008, but was far behind high ratio of high risk RIS patients(85.45%). Conclusions This retrospective study showd an increasing trend in RIS risk during 2001-2008. Identifying high risk patients and applying intensified antiplatelet therapy might play an important role in reducing the risk of RIS.

Objective Percheron artery is an uncommon anatomic variant. Percheron artery infarction with unilateral embryonic posterior cerebral artery ( PCA ) was rarely reported.The aim of this study was to characterize the clinical and imaging patterns of Percheron artery infarction with the unilateral embryonic PCA for early diagnosis and treatment.MethodsClinical and imaging data of 2 patients with Percheron artery infarction were reviewed retrospectively.ResultsTwo patients presented acute coma and one had paroxysmal blurred before coma.On neurological examinations,one patient had vertical gaze palsy besides two were unconsciousness. MRI showed symmetrical high signal intensity on diffusion weighed imaging (DWI)in bilateral paramedian thalami in two patients and a distinct pattern of V-shaped hyperintensity on DWI andFLAIR was present on the midbrain in one patient. Digital subtraction angiography and magnetic resonance angiography demonstrated unilateral embryonic PCA in two patients.ConclusionsThe classical clinical symptoms,symmetrical high signal in bilateral paramedian thalami and V-shaped sign in midbrain on DWI can improve recognition,evaluation and management of Percheron artery infarction.The unilateral embryonic PCA may be underlying risk factor of Percheron artery infarction.

Objective: To study therapeutic effects of simvastatin on vascular endothelial cell dysfunction in patients with coronary heart disease (CHD). Methods: According to LDL-C level, a total of 90 CHD patients were divided into simvastatin 20mg group (n=37, LDL-C≥2.5mmol/L), simvastatin 10mg group (n=35, 1.8mmol/L≤LDL-C<2.5mmol/L) and routine treatment group (n=18, LDL-C<1.8mmol/L). Their course of treatment was 8 weeks. Color Doppler ultrasound diagnostic instrument was used to measure flow-mediated dilation of brachial artery (FMD), and nitrate reductase method was used to measure concentration of nitric oxide (NO) in all CHD patients. Serum concentrations of TC, TG, LDL-C and HDL-C were routinely measured. Results: After treatment of eight weeks, compared with before treatment, there were significant decrease in concentrations of TC, TG and LDL-C (P<0.05 all), and significant increase in HDL-C level (P<0.05 all) in simvastatin 20mg and 10mg group, but there were no significant difference in above-mentioned all indexes between simvastatin 20mg and 10mg groups, P>0.05 all; Compared with routine treatment group, there were significant improvement in FMD [(6.01±0.49)% vs. (9.01±0.39)% vs. (9.01±0.47)%,P<0.01 all] and significant increase in serum NO concentration [(38.97±8.89)μmol/L vs. (47.67±10.89) μmol/L vs. (45.61±9.09) μmol/L,P<0.05 all] in simvastatin 20mg and 10mg group; But there were also no significant difference in serum NO and FMD between simvastatin 20mg and 10mg groups, P>0.05 all. Conclusion: Simvastatin can increase NO concentration and improve vascular endothelial cell dysfunction in CHD patients. Its mechanism may be related with lipid-lowering effect, but independent of its lipid-lowering effect
