Objective To investigate the relationship between microalbuminuria (MAU) and the risk factor for acute ischemic stroke,the severity of the disease and outcomes.Methods A total of 156 consecutive patients with acute ischemic stroke were enrolled prospectively.They were randomly divided into either an MAU positive group (≥ 30 mg/g) or an MAU negative group (＜ 30 mg/g) according to urinary albumin/creatinine ratio (UACR).They were also randomly divided into either a good outcome group (0-2) or a poor outcome group (＞2) according to the modified Rankin scale (mRS) scores.The various demographic and clinical data were compared,and the poor outcome of acute ischemic stroke and the independent factors of positive MAU were analyzes.Results A total of 156 patients with acute ischemic stroke were enrolled,including 84 males and 72 female; aged 53 to 78 years (mean 65.4 ± 6.2); the time from onset to admission was 1.5 to 28 h; 94 patients had good outcomes,62 had poor outcomes,and no one died; MAU was positive in 76 patients and MAU was negative in 80 ones.Multivariate logistic regression analysis showed that advanced age (odds ratio [OR] 1.992,95％ confidence interval [CI] 1.108-2.374; P =0.015),complicated with diabetes (OR 2.497,95％ CI 1.177-5.298; P =0.017) and atrial fibrilhtion (OR 2.338,95％ CI 1.062-5.148; P =0.035),high serum homocysteine (Hcy) level (OR 2.541,95％ CI 1.073-6.02; P =0.047) and UACR (OR 2.130,95％ CI 1.396-3.017; P =0.001),MAU positive (OR 3.291,95％ CI 1.681-6.444; P =0.001),high baseline National Institutes of Health Stroke Scale (NIHSS) score (OR 9.196,95％ CI 2.828-19.815; P＜ 0.001) were the independent risk factors for poor outcomes in patients with acute ischemic stroke.There were significant differences in the proportion of the patients complicated with diabetes (P =0.038) and fasting blood glucose level (P =0.025),serum Hey level (P =0.022),and carotid intima-media thickness (IMT) (P =0.019) between the MAU positive group and the MAU negative group.The proportion of anterior circulation infarction was lower (P =0.033),the rates of the baseline NIHSS score (P =0.003) and poor outcome were higher in the MAU positive group (P ＜ 0.001).Multivariate logistic regression analysis showed that increased diabetes (OR 2.237,95％ CI 1.036-4.829; P =0.040) and fasting blood glucose (OR 1.223,95％ CI 1.145-1.673; P =0.027),the increased Hey level (OR 2.542,95％ CI 1.047-6.612; P=0.025),carotid artery IMT (OR 1.295,95％ CI 1.106-1.362; P =0.023) and baseline NIHSS score (OR1.206,95％ CI 1.044-1.219; P =0.023) were correlated independently with the positive MAU in patients with acute ischemic stroke.Conclusions Positive MAU is one of the independent risk factors for poor outcomes of acute ischemic stroke,it is closely associated with some risk factors for acute ischemic stroke,and it has a significant impact on the severity of acute ischemic stroke and outcomes.

Non-bifurcating cervical carotid artery(NBCCA)is a very rare anatomical variation of the cervical carotid artery,which may be related to the abnormal development of internal carotid artery(ICA)and external carotid artery in embryonic period.Neither carotid bulb nor a true carotid bifurcation can be observed on the ultrasound of carotid artery while a"stump-like"change was showed at the expected bifurcation level of carotid artery on DSA.Few cases has been reported in China and abroad so far.This article reported a middle-aged male with a history of hypertension and type 2 diabetes and was admitted to the hospital due to dizziness for one month.The left NBCCA accompanied with severe stenosis of the right ICA was confirmed by cerebral angiography.The patient received the right ICA stent implantation surgery as well as antihypertensive and glucose-control treatment and was discharged as his symptoms improved.Clinical data of this case and related literatures were reviewed,in order to improve clinicians'especially imaging diagnostic physicians'understanding on NBCCA to avoid misdiagnosis and related complications.

The construction of National Regional Centers is a significant strategic deployment to promote the expansion of high-quality medical resources and a balanced regional layout.It introduces the performance of Peking University First Hospital in promoting the construction of National Regional Centre for women and children's hospital with the work mode of"geographical homogenization construction",summarizes effectiveness.It is believed that government support is the foundation,output hospital sinking is the key,and input hospital participation is the guarantee.
