Objective To explore the changes of hemodynamic after carotid angioplasty and stenting ( CAS) in patients with carotid artery stenosis .Methods Thirty-one carotid artery stenosis patients were treated with CAS , and were examined by color Doppler flow imaging ( CDFI) before operation and 1 d,3 months,one year after operation . Compared the carotid artery diameter , peak flow velocity (PSV) and end-diastolic velocity (EDV) before and after the operation.Results Compared with before operation , carotid artery diameter were significantly increased ,PSV, EDV were significantly decreased at each time point after operation ( all P<0.01 ) .Compared with 1 d after operation, there was no statistical difference on the CDFI results of carotid artery in 3 months after operation;compared with 1 d after operation the carotid artery diameter was significanty decreased in one year after operation ( P<0.05 ) , there was no statistical difference in PSV and EDV .Conclusions CAS can alleviate the carotid stenosis and improve the indicator of hemodynamics significantly .Vascular restenosis is found in some patients one year after operation , but there was no statistical difference in the indicator of hemodynamic .

Objective Investigate the efficacy of Plaix and Aspirine on treating the patients with progressive cerebral infarction.Methods 92 patients with progressive cerebral infarction were randomly divided into unite therapy group(n=46) and control groups(n=46).Two groups were taken the conventional therapy.In the patients of unite therapy group,oral Plaix 75 mg and Aspirine 150 mg per day,control group oral Aspirine 150 mg per day.Clinical neural deficiency score(NDS) was given before and 30 d after treatment for comparison and measur blood solidifying function and Heraorheological indexes.Results Total effective rate in the unite therapy group(93%)was significant higher than that in the control group(74%)(P

Objective To explore the relationship between the posterior circulation ischemia(PCI) and vertebrobasilar artery lesion.Methods 57 patients with PCI(PCI group) were examined by DCE-MRA for their craniocervical artery,and the results were compared with the stroke inpatients but non-PCI during the same period(non-PCI group).Results The abnormal rate of vertebrobasilar artery in PCI group(70.2%)was significantly higher than that in non-PCI group(50.7%)(P

Objective To observe clinical effect of hyperoxia solution in the treatment of acute cerebral infarction(ACI).Methods 218 cases of ACI were divided randamly into hyperoxia solution therapy group(group H,n=116)and conventional therapy group(group C,n=102).500 ml hyperoxia solution were intravenously dripped in group H once per day,and the other conventional therapy were the same in two groups.The course of treatment for the two groups were 20 days.Results After treatment,the general effective rate of group H(84.4%)was significantly higher than that of group C(72.54%)(P

Objective To compare the effects of intra-sinus thrombolysis by using urokinase and heparin anticoagulation alone for cerebral venous sinus thrombosis (CVST).Methods Consecutive inpatients with CVST were enrolled retrospectively.Their demographic and clinical data were collected.The treatment mainly consists of intra-sinus thrombolysis by using urokinase and heparin anticoagulation alone.The outcomes were evaluated according to the modified Rankin scale (mRS) at 6 months.The mRS score ＜ 2 was defined as good outcome,and ≥2 was defined as poor outcome.Results A total of 36 patients were enrolled,including intra-sinus thrombolysis by using urokinase (n =18) and heparin anticoagulation alone (n =18).Twenty-one had good outcomes and 15 had poor outcomes.After treatment,the recanalization rate (94.4％ vs.66.7％ ;x2 =3.850,P=0.041) of the urokinase thrombolysis group and the good outcome rate at 6 months (72.2％ vs.44.4％ ; x2 =3.827,P =0.046) were significantly higher than those of the heparin anticoagulation group.The proportion of the patients receiving intra-sinus thrombolysis by using urokinase of the good outcome group was significantly higher than that of the heparin anticoagulation group (60.0％ vs.18.2 ％ ; x2 =5.360,P =0.021).Multivariate logistic regression analysis showed that the intrasinus thrombolysis by using urokinase was an independent protective factor for good outcomes in patients with CVST (odds ratio,1.085,95％ confidence interval 1.024-1.361; P=0.023),and the high coagulation state was its independent risk factor (odds ratio,0.185,95％ confidence interval 0.049-0.611;P=0.004).None of the patients occurred symptomatic cerebral hemorrhage.Conclusions Intra-sinus thrombolysis with urokinase may improve the outcomes for patients with CVST,and it is superior to the heparin anticoagulation alone.

One hundred ten patients with Parkinson′s disease(PD)and 110 age-matched healthy controls were enrolled in the study.The non-motor symptoms(NMS)were assessed with Non-motor symptoms of Parkinson′s disease questionnaire(PDNMSQ30).The PD patients were classified as gait abnormality posture type(PIGD, n=73)and tremor type(TD, n=37).The non-motor symptoms were compared between two groups.Results showed that the NMS in PD patients was higher than that in healthy controls[(35.2 ±3.0)vs.(6.0 ±2.0)symptoms, t=6.43, P=0.01].The NMS score of PIGD group was higher than that of TD group[(28.9 ±1.1)vs.(6.2 ±0.7)symptoms, t=2.73, P<0.01]; Mini-mental state examination(MMSE)and Montreal cognitive assessment scale(MoCA)scores of TD group were significantly higher than those of PIGD group(t=11.52,P<0.01; t=8.79,P<0.01).The results indicate that for PD patients with different motor types,their NMS are different,and PD patients with PIGD have more axial involvement,and more NMS.
