RESUMO
Objective To evaluate the clinical value of multi-slice spiral CT (MSCT)in the screening of coronary artery lesions in elderly patients with diabetes mellitus.Methods MSCT and coronary angiography(CAG)were performed in 136 elderly patients(68 patients with diabetes and 68 patients without diabetes).The number of diseased coronary segments and the plaque type (noncalcified,mixed and calcified)for each patient were determined.The characteristics of coronary lesions were compared between patients with and without diabetes.The sensitivity and specificity of MSCT were evaluated.Results More noncalcified and calcified plaques and few ermixed plaques were observed in patients with diabetes,compared with patients without diabetes(noncalcified plagues:10 cases or 14.7％ vs.4 cases or 5.9％;calcified plagues:47 cases or 69.1％ vs.39 cases or 57.4％)(P＜ 0.05).In addition,diabetic patients showed a significantly higher frequency of multivessel disease(P＜0.05).Furthermore,MSCT was able to clearly show stenosis and plaque type in the trunk and branches of the coronary artery,with a sensitivity of 91.0％,a specificity of 95.0％,a positive predictive value of 93％ and a negative predictive value of 96.0％.Conclusions Diabetes is associated with a higher risk of coronary artery disease.MSCT can effectively detect the characteristics of coronary artery disease in diabetic patients and is an effective,noninvasive,and safe screening method.
RESUMO
Filial piety and fraternal love ethics is the nucleus of tradition ethics and the base of a person's moral.Reinforcing filial piety and fraternal love education is beneficial to raising the medical students'morality and qualities,consummating their personality,raising their brotherhood life,easing up doctor-patient relationship and promoting the development of medical health.
RESUMO
Marx had assumed that it was possible for the Russian countryside commune to stride over the capitalist “Kafuting Gorge” and thus straightly realize communism. Using the Marxist theory, this paper dialectically expounds the necessary conditions under which man realizes its bestriding development: the internal superiorities, the external conditions, and the power and content of the bestriding.
