RESUMO
Objective To evaluate the feasibility of CEUS in Crohn discasc (CD) activity.Methods Thirty-nine patients with CD were analyzed.The clinical disease activity index of 18 cases were less than 150 (inactivity),and 21 cases were between 150 and 450 (activity).The thickness of intestinal walls were measured and Limberg classification were determined by power-Doppler results.The CEUS was performed,and the parameters including rise time,peak intensity,mean transit time,time from peak to one half,wash in slope and time to peak were statistical analyzed.Results The thickness of the lesions,peak intensity and wash in slope of activity CD were greater than those of inactivity CD,which had significant difference (all P＜0.05).The Limberg classification of type Ⅰ was 1 case,type Ⅱ was 4 cases,type Ⅲ was 10 cases and type Ⅳ was 6 cases in activity CD.The Limberg classification of type Ⅰ was 10 cases,type Ⅱ was 7 cases and type Ⅲ was 1 case.The Limberg classification were mainly type Ⅲ and type Ⅳ in activity CD,and type Ⅰ and type Ⅱ in inactivity CD,which had significant difference (P＜0.001).Conclusion CEUS can provide quantitative parameters in CD activity and has great clinical value.
RESUMO
Objective To investigate the correlation between plasma cystatin C (CysC) level and carotid atherosclerotic plaque in patients with ischemic stroke.Methods The clinical data in patients with acute ischemic stroke were analyzed retrospectively.According to the results of carotid artery ultrasound,the patients were divided into either a non-plaque group or a plaque group.Then the plaque group was redivided into a stable plaque subgroup and a vulnerable plaque subgroup.Multivariate logistic regression analysis and Pearson correlation analysis were used to explore the risk factors for carotid atherosclerotic plaque.Results A total of 226 patients with acute ischemic stroke were enrolled,172 of them had carotid plaque,and 54 had no plaque.Of the patients with carotid plaque,94 were stable plaque and 78 were vulnerable plaque.The age (71.82 ± 9.94 years vs.60.74 ± 13.81 years; t =6.160,P =0.014),proportion of patients with ischemic heart disease (11.6％ vs.1.9％; x2=6.169,P=0.020),systolic blood pressure (148.770± 21.007 mm Hg vs.142.240 ± 19.404 mm Hg; t =2.029,t =0.044),plasma CysC concentration (1.046 ± 0.438 mg/L vs.0.860 ±0.214 mg/L; t =3.006,P =0.003),and carotid IMT (1.122 ±0.278 mm vs.0.878 ±0.250 mm; t =5.762,P=0.000) in the plaque group were significantly higher than those in the non-plaque group.Multivariate logistic regression analysis showed that the age (odds ratio [OR] 1.079,95％ confidence interval [CI] 1.044-1.116; P=0.000) and IMT (OR 31.450,95％ CI 6.233-158.692; P=0.000) was the independent risk factor for carotid plaque,while there was no significant independent correlation between the plasma CysC level and carotid plaque (P =0.217).Only IMT in the stable plaque subgroup was significantly higher than the vulnerable plaque group (1.176 ±0.285 mm vs.1.058 ±0.258 mm; t =-2.824,P =0.005),and it was the independent protective factor for the carotid plaque stability (OR 0.195,95％ CI 0.059-0.064; P =0.007).Pearson correlation analysis showed that the plasma CysC level was positively correlated with the age (r =0.375,P =0.000) and serum creatinine level (r =0.462,P =0.000),but it was not significantly correlated with carotid IMT (r =0.075,P =0.264).Conclusions In patients with ischemic stroke,no correlations were found between the plasma CysC level and carotid atherosclerotic plaque,plaque stability,and IMT.
RESUMO
Objective To investigate the diagnostic value of color Doppler ultrasonography in congenital muscular torticollis (CMT). Methods The sonographic characteristics of 62 children with CMT confirmed clinically were retrospectively analyzed. Results Abnormal ultrasound features could be visualized in all of 62 children with CMT. According to the sonogram features, 62 children were divided into 2 types: mass-forming (32/62, 51.61%) and diffuse type (30/62, 48.39%). Arterial flow signals were detected in 18 children (18/62, 29.03%); RI was 0.73-0.88. Conclusion Ultrasonography has specific value for the diagnosis of CMT.
