ABSTRACT
@#Objective To determine the value of accommodation quotient (AQ) on dysphagia evaluation in the elderly. Methods 40 old cases with dysphagia were assessed with AQ, Kubota Water Swallow Test (WST) and Swallowing Evaluation (SE) before and after 3 weeks of treatment. The patients were divided into 2 groups based on the first AQ assessment: mild group (AQ=1.5~2.5) and serious group (AQ< 1.5). Results There was not significant difference in scores of WST between both groups (P>0.05) but SE (P<0.05). The AQ before treatment moderately correlated with the scores of WST and SE before treatment and improvement (P<0.001), and SE after treatment (P<0.001), but did not correlate with the score of WST after treatment (P>0.05). Conclusion The AQ may indicate the function of swallowing in the elderly, and predict the outcome of dysphagia.
ABSTRACT
Purpose A new way in breast cancer detection, Dynamic Optical Breast Imaging (DOBI) was studied. Materials and Methods 52 patients receiving breast biopsy and DOBI were enrolled in this study. 19 were proved of breast cancer, 33 were benign. Results 94.8% of blue area in non-breast cancer lesions was found as wandering or diffusive pattern, while 68.42% breast cancer showed focal pattern. 86.46% of the curve signature of blue area in non-breast cancer lesions was wavy or flat, while 57.37% of breast cancer showed a steep decline. In 64.58% non-breast cancer, the curve of blue area was similar to that of non-blue area. 78.95% breast cancer had their curve different from that of non-blue area. The absolute value of amplitude (-5.77±2.13) of blue area in cancer was higher than that in non-cancer ( -3.34±0.87). The differences were all statistically significant(P<0.05). Conclusion The spatial and temporal characteristics of DOBI were of diagnostic and differential value for breast cancer. The absolute value of amplitude, over|-5|, also helped the diagnosis of breast cancer.
ABSTRACT
Objective To assess the changes of the cardiac function of the patients with myocardial infarction(MI) after the coronary revascularization(CRV) by 2D echocardiography and Doppler tissue imaging(DTI).The effects of CRV on cardiac function were explored.Methods The global and regional wall functions were quantitatively analyzed in 49 patients with MI by 2D echocardiography and DTI(Aspen imaging systems).Results The regional function was improved prior to the global function in patients with MI after successful CRV.Conclusions CRV is one of the important factors for the cardiac function improvement in patients with MI.
ABSTRACT
Objective To evaluate the left ventricular systolic function of the patients who received coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI), in order to compare the clinical effectiveness of these two operations. Methods 61 patients with coronary artery disease were enrolled in this study. 28 patients received CABG and 33 patients PCI. The left ventricular systolic function was assessed by two-dimensional (2D) echocardiography and Doppler tissue imaging (DTI) (Aspen imaging systems). Results The left ventriculus ejection fraction (EF) and the average velocity of systolic wave (S) of mitral annular were increased after CABG or PCI. There was no statistical significant difference in degree of improvement in the left ventricular systolic function between two operations. Conclusions The results of this study suggested that the global left ventricular systolic function was improved after either successful CABG or PCI, with no signiticant difference in clinical efficaciousness.

0.05).Both of them had a linear correlativity,correlative coefficient closed to 1.Conclusions Coronary artery endothelial function and brachial artery endothelial function had a high linear correlativity.
ABSTRACT
To evaluate the left ventricular diastolic function with Doppler and 2D echocardiography in patients with mild and moderate hypertension. 202 patients with hypertension were involved in this study. The parameters of Doppler and 2D echocardiography were compared with clinical materials of the patients. The results of this study showed that age, diabetes, left ventricle hypertrophy and duration of hypertension were related to the left ventricular diastolic function, whereas hyperlipidmia, smoking and alcohol drink had less effect on left diastolic function. The results of this study suggested that there were diastolic dysfunction in patients with hypertension, and Doppler and 2D echocardiography could be used to detect left ventricular diastolic function.
