ABSTRACT
ObjectiveTo investigate the value of shear wave elastography (SWE) in the evaluation of liver damage in patients with Budd-Chiari syndrome (BCS).MethodsSixteen patients with BCS which were all conifrmed by interventional therapy or inferior vena cava angiography were enrolled in the study. And iffty healthy volunteers who were conifrmed with no liver disease history, no surgical history and no metabolic disease such as diabetes were included in this study. All the subjects underwent conventional ultrasound and no obvious abnormality was detected. All the BCS patients and the volunteers underwent SWE. The elastic graph and the quantitative elastic value, including the average value, the maximum value and the minimum value, were acquired and compared between BCS patients and the volunteers.ResultsThe elastic graphs for the healthy volunteers were uniform light blue while the elastic graphs for BCS patients were hybrid images of blue, green and yellow. The average value, the maximum value and the minimum value of BCS patients were (18.1±9.4) kPa, (20.6±10.5) kPa and (15.5±8.5) kPa, which were statistically higher than those of healthy volunteers [(6.2±1.0) kPa, (7.5±1.2) kPa and (4.8±1.1) kPa,t=7.69, 8.94 and 7.83, allP<0.01].ConclusionsSWE can reflect the liver damage of patients with BCS before the change of the two-dimensional ultrasound. It can play an important role in the accurate selection of treatment and the accurate evaluation of treatment effect and the prognosis.
ABSTRACT
Objective To determine the socioeconomic factors and main causes of treatment failure among bacillary-positive pulmonary tuberculosis patients in Shanghai.Methods A 1:1 matched case-control study was performed.Ninety two cases who were treated longer than 18 months,and 85 controls who completed treatment during 2003-2004 in Shanghai were selected.Cases and controls were matched by sex,age,and previous treatment.Results Adjusted by sex,age,and previous treatment,the associated factors of treatment failure among bacillary-positive pulmonary tuberculosis patients were drug resistance (?2=14.764,P
ABSTRACT
Huaihua medical College has inquired into the questionnaire from more 500 students who are clinical doctors and graduate nurses and 50 teachs who are clinical teaching hospitals,finding that the results have indicated the significance,the necessity and the actual problems of clinical technical ability practice teaching,when they are in school by their firsthand experience,which are very helpful to shortening scheduled time to practice,improving clinical basic skills,adjusting to medical environment as soon as possible,to ensure practice teaching quality and also have notable effects on continuing reinforcing building the clinical technical ability training centre and improving the quality of clinical technical teaching ability at the same time.
