Artery left circumflex were isolated by operation,and artery LCX thrombosis was formed using endangium rough combined with electrostimulator.

手术分离冠状动脉左旋支，以血管内膜粗糙+电刺激法形成冠状动脉左旋支血栓，检测静脉注射不同剂量reteplase后对冠状动脉左旋支血流量、栓塞再通率、心肌梗死范围、伤口失血量和末梢出血时间的影响。

Methods: Twenty coronary arteries from eight perfusion-fixed autopsy heart were dissected, straightened and scanned by UFCT. Then each coronary artery was divieded into ocrresponding segments, representative histological 3 mm sections were stained with Orcein. Atherosclerotic area(mm2) and luminal narrow per segment were quantified on Leica Imaging System.

Results Compared with percutaneous coronary angiography,the sensitivity of sixteen slice sparil CT in diagnosing moderate and severe coronary stenosis was 83.05%,and the specificness,positive predictive value,negative predictive value and degree of accuracy was 95.97%,89.09%,93.46% and 92.31% respectively.

结果 16层螺旋CT冠状动脉造影对照经皮选择性冠状动脉造影对冠状动脉中、重度狭窄显示的对照结果：敏感性83.05%、特异性95.97%、阳性预测值89.09%、阴性预测值93.46%、准确度92.31%。

Methods There were 102 cases in this study , 78 cases in tortuosity group and 24 cases in non-tortuosity group. All the patients received coronary angiography and rest electrocardiography , and part of them did exercise test because of suspected angina.

将102例冠状动脉造影无明显狭窄病变的胸痛患者分为冠状动脉迂曲组78例和无迂曲组24例，观察两组胸痛发作情况、临床用药效果、冠状动脉造影特点和心电图及运动试验的特点。

Stens were evaluated to be patent, while 1 stent was not patent. Conclusion: Sixteen slice spiral CT scan of the cardiac coronary artery is a noninvasive,simple and good method. Coronary calcium score and coronary artery stenosis can be evaluated within one study. The patency of stents could also be evaluated. But more experience in more cases of comparative study should be obtained to prove the accuracy of the evaluation of stenosis of coronary arteries and patency of stents.

十六层螺旋CT冠状动脉CT动脉造影(CTA，computer tomography angiography)是一种无创、简便、优良的冠状动脉成像方法，可一次检查完成冠状动脉钙化积分和狭窄评价，也可评价支架通畅情况，但其评价狭窄及支架通畅的准确性有待做更多病例的CTA与常规冠状动脉造影的对照研究。

Results Reconstructive coronary artery images of 1 patient with severe sinus arrhythmia were not displayed clearly.

结果 在56例行MSCT冠状动脉造影的患者中1例由于患者有严重的窦性心率不齐，重建图像质量欠佳，其余患者均成功显示冠状动脉各主支（左主支、回旋支、前降支右支冠状动脉）及部分3、4级分支，且可显示所有冠状动脉支架的形态、位置，其中18例患者的31个支架术后出现再狭窄，所有行MSCT冠状动脉造影检查的患者无一例出现并发症，所有CT诊断支架术后再狭窄的患者同时行选择性血管造影检查，其中14例患者的25个支架有支架术后再狭窄，CT诊断的准确率为80.65%。

The 4th left rib was cut and a model of left coronary artery occlusion/release was carried outo Rats were divided randomly into 4 groups: control group without LCA occlusion (group A, n=6);I/R group(group B, n=6); ketamine(5mg.kg-1)+I/R group (group C, n=6); ketamine(10mg.kg-1)+I/R group(group D,n=6)o All rats in groups B, C , D were subjected to 30 minutes of LCA occlusion followed by 120minutes of reperfusion. Rats in group C and D were injected with 5mg.kg-1 and 10mg.kg-1 of ketamine before reperfusion, respectively. Significant electrocardiogram and color changes at the area at risk were considered indicative of successful coronary occlusion and reperfusionc Serum was exampled from left jugular vein at 30 minutes and 120 minutes during reperfusion to measure IL-6 and TNF- level by ELISA measurements. After reperfusion of 120 minutes, the heart was removed and the cardiac apex was exampled with snap-frozen in liquid nitrogen and stored at -70 C .

采用左冠状动脉前降支结扎开放建立心肌缺血／再灌注模型，健康SD大鼠24只，随机分为心包打开假手术组(A组，n=6)，缺血／再灌注对照组(B组，n=6)，5 mg·kg~(-1)氯胺酮+缺血／再灌注组C组，n=6，缺血30min后右腹股静脉注入5 mg·kg~(-1氯胺酮，10mg·kg~(-1)KTM+I／R组D组，n=6，缺血30min后右腹股静脉注入10 mg·kg~(-1氯胺酮。10％水合氯醛40 mg·kg~(-1)腹腔注射麻醉，气管切开，连接多功能监护仪记录心电图；小动物呼吸机人工呼吸，呼吸频率60次／分，潮气量2ml／100g，于左胸第四肋间打开胸腔暴露心脏，在左心耳下1mm左冠状动脉处，用丝线，眼科外用不锈钢小圆针穿过心肌浅层，稳定10min后将U型含有铜丝的胶管置于冠状动脉表面一起结扎(A组不结扎，B、C、D组结扎)；结扎开始左心室心尖部即由红色变暗，30 min后呈暗红色，心电图中出现S-T段抬高，说明缺血形成。
