The optimal therapeutic regimen for patients with asymptomatic carotid artery stenosis (ACS) has been controversial.Early research suggests that carotid endarterectomy (CEA) is effective for the treatment of patients with severe ACAS.In recent years,as a minimally invasive treatment,carotid artery stenting (CAS) is as effective as CEA.It has a trend of replacing CEA.In recent 10 years,medicine standardized treatment has made great progress.Recent studies have shown that the risk of stroke is lower using the optimal medical treatment in patients with ACAS compared with CEA and CAS.The key of choosing optimal therapeutic regimen is to identify the high risk patients with stroke.

Minor stroke is characterized by the mild symptom and rapid recovery,and does not easily cause disability,but a part of patients with minor stroke are the high risk population of recurrent stroke,and can cause disability,cognitive impairment,and emotional disorders.Early prediction of the prognosis in patients with minor stroke,screening for the high risk population of recurrent stroke and disability,and giving appropriate treatment may prevent recurrent stroke and improve the prognosis of patients.This article reviews the predictors of prognosis in patients with minor stroke.

Objective To explore association between serum albumin level and cognitive performance in elderly Chinese.Methods All the subjects aged ≥65 years in the 8 longevity areas in Chinese longitudinal health longevity survey (CLHLS) were invited to participate the biomedical in-depth CLHLS study,information about subjects' demographic characteristics,lifestyle,prevalence of diseases and health status was collected through household-interview.The cognitive performance was assessed with Mini Mental State Evaluation (MMSE) scale.Health examination was conducted by medical personnel and fasting venous blood samples were collected to detect the levels of triglycerides,total cholesterol,fasting glucose,creatine and blood albumin.MMSE score was compared and the trend was analyzed with generalized linear model.Association between albumin concentration and cognitive impairment was analyzed by logistic regression model.Results Generalized linear model showed that adjusted MMSE score increased from 23.22 in the lowest quartile group to 25.07 in the highest quartile group (P for linear trend ＜0.001).Logistic regression analysis results showed that the higher albumin level was associated with the lower risk of cognitive impairment (P＜ 0.001),the OR decreased linearly with the increasing level of albumin (P＜0.01),with the OR (95％CI) for the lower,higher and highest quartile groups was 0.64(0.45-0.91),0.60(0.40-0.89) and 0.43 (0.27-0.69),respectively,compared with the lowest quartile group.Conclusion High level of serum albumin was associated with low risk of cognitive impairment.
