2.Conclusions Multiform biliary internal and/or external drainage is effective for most patien ts with MBO.
4.After investigation of many experimental data of stress concentration of joints and numerical computation of 100 examples of T joints subjected to axial and out-plane bending load, the intersection curves between stress concentration factor and geometric parameters α, β, γ, rand the stress concentration factor tables of T joints are provided. Thee reliability analysis of these tables are also presented.
5.In this study the result of coronary artery angiography was as the standard. The stress test of combined dipyridamole and transesophageal atrial stimulation with echocardiography, the stress test of combined dipyridamole with echocardiography(DPE) and the stress test of transesophageal atrial stimulation with echocardiography(TEE) were performed in 60 patients with uncomplicated acute myocardial infarction, on the seventh day and the fourteenth day after infarction.
