Methods Fifteen dogs were randomly divided into 3 groups. Group A acted as the control group without CPB; group B and group C were subjected to cardiopulmonary bypass and crossclamping the aorta for 90 min. MP or saline was injected intravenously before surgery. Plasma levels of IL-1β、TNF-α、IL-6、IL-8 and IL-10 were measured at the following time points: before MP or saline were administered, aortic declamping, 30 min and 90 min, after aortic declamping. Immediately after the animals was killed, pulmonary arterial rings were obtained and mounted in organ chamber for assessment of endothelial function with endothelium-dependent or non-endothelium-dependent studies.

Among them, 20 patients were candidates of valve replacement and 18 PDA and pericarditis had their blood samples taken before operation,and 1,2,24 and 48 hours after closure of thorax for measurement of concentrations of CK、CK-MB and TnT,together with ECG recording. Results Of the 60 patients, concentrations of cTnT before operation were normal; 2 hours after aortic unclamping, the correlation coefficient between cTnT and aortic clamping was r = 0.873( P＜0.01), the regression analysis showed Y = 0. 019X-0. 026. Of the 20 patients, ECG showed the myocardium was ischemic; CK、CK-MB and cTnT all rose significantly, reaching the peak after closure of thorax. Of the 18 patients, the ECG and cTnT before operation and after closure of thorax were normal; except 2 patients with pericarditis.

aorta：主动脉

2.主动脉(aorta)是体循环的动脉主干,起于左心室,向右前上方上升,以后向左后方呈弓形弯曲,到第4胸椎平面,沿脊柱左侧下降,穿过膈的主动脉裂孔,在腹后壁继续下降,至第4腰椎而分成左、右二髂总动脉.

artery：动脉
