冠状动脉的

The first part consists of three experiments:(1) The rings were incubated in KH, 20, 50 mmol/L 〓 for 1 house, relaxation in response to the EDHF stimuli A23187 in 30nmol/L U46619-induced preconrtaction in the presence of 7 μ mol/L indomethacin, a cyclooxygenase inhibitor, 300μmol/L LNNA, a nitric oxide biosyhnthesis inhibitor, and 1mmol/L tetraethylammonium , a 〓 blocker, or 3 μmol/L glibenclamide , a 〓 blocker, was compared with the control;(2) After the arteries were incubated in KH, UW solution or HTK solution at 4℃ for 4 hours, endothelium-derived relaxation (percentage of 30nmol/L U46619 precontraction) was induced by A23187 in the present of 7 μmol/L indomethacir and 300μmol/L LNNA;(3) After incubation with KH, UW solution and STH (either at 37℃ in oxygenated organ chamber or at 4℃ in a refrigerator for 4 hours), endothelium-derived relaxation (percentage of 30nmol/L U46619 precontraction) was induced by A23187 in the present of 7 μ mol/L indomethacin and 300 μmol/L LNNA.

第一部分研究结果：（1）单纯浸泡于KH的冠状动脉A23187能引发66.67％的血管舒张反应，经TEA及20mmol／L、50mmol／L钾离子作用后，血管舒张反应程度显著降低，但经GBM作用后改变不明显；（2）与保存于KH的冠状动脉相比，A23187引发的血管舒张反应程度，保存于UW液的明显下降，保存于HTK液的无明显变化；（3）在37℃条件下，血管环浸泡于STH出现缓慢轻微的舒张反应，浸泡于UW液初期出现短暂收缩反应，但此后主要以舒张为主：在37℃条件下，血管经UW液保存后，U46619引发的收缩反应程度降低；不论在37℃或4℃条件下，A23187引发的血管舒张反应，经UW液保存后明显下降，但用STH保存后变化不明显。

CAC was identified in 2003 as a cardiovascular disease risk factor and an independent predictor of mortality. Investigators have known since at least 1996 that CAC is from 2 to 5 times more extensive in people on hemodialysis than in people with coronary artery disease but not kidney disease, said Dr. Asci, a nephrologist at the Ege University School of Medicine in Izmir, Turkey. Subsequent studies have shown an association between CAC and left ventricular hypertrophy and coronary abnormalities, including atherosclerosis, stiffness, and perfusion problems.

土耳其Lzmir Ege大学医学院肾脏科医师Asci医师表示，CAC在2003年即被确认为是心脏血管疾病的危险因子，同时也是独立的死亡率预测因子；研究者早在1996年就知道，相较於无肾脏疾病之冠状动脉疾病患者，透析病患CAC的情形普遍2~5倍；接下来的研究结果显示，CAC与左心室肥大与冠状动脉血管异常，包括粥状动脉硬化、血管硬化、与灌流异常是有关连的。

Objective: To determine if an aggressive approach to coronary revascularisation with oversized balloons is counterproductive, we studied the effect of increasing balloon-to-artery ratio on neointimal hyperplasia following primary stent placement using a non-atherosclerotic porcine coronary overstretch model.

目的：为了确定在冠状动脉重建术中使用过大的球囊这种过于积极的措施是不是有反作用，我们研究了首次支架置入术后增加的球囊比动脉比值对新生内膜增生的影响，模型是没有动脉粥样硬化的猪的过度牵张的冠状动脉。

(1)The levels of MCP-1 and VEGF'levels was significant increased in CHD patients,Compared with controls, It was implicated that they might take part in the actions of informing atherosderotic plaques;(2)The serum level of MCP-1 and VEGF were elavated step by stey among the group of controls、SAP、UAP、AMI, It was thought they might develop the matter on the stability of atherosderotic plaques;(3)The serum level of MCP-1 and VEGF were positive correlated with 7-TIMI risk score, It prompt that MCP-1 and VEGF was the reactiveness markers of coronary artery process ,and developed the risk to major acute cardiac events.

(1)血清MCP-1、VEGF水平在冠心病患者中显著升高，提示MCP-1、VEGF可能在促进冠状动脉粥样硬化斑块形成的过程中起重要作用；(2)血清MCP-1、VEGF水平在对照组、各冠心病亚组(SAP、UAP、AMI组)之间逐级升高，提示MCP-1、VEGF可能增加了冠状动脉粥样硬化斑块的不稳定性；(3)联合检测MCP-1、VEGF的灵敏度\特异度上升，证明临床上联合检测二者血清指标意义大；并且血清MCP-1、VEGF水平和7-TIMI积分呈正相关性，7-TIMI积分高的患者血清MCP-1、VEGF水平也高，说明它们能作为冠脉病变的活动性标志物，可能成为评价主要心血管恶性事件的危险性的相关指标。

The optimal reconstruction windows of patients with stable HR(≤75 bpm and≥91 bpm) were concentrated in 71%,ranged from 65%-80%, and in 41%,ranged from 32%—50%,respectively.The prospectively ECG-gated DSCT coronary angiography can be used in patients with stable HR(≤75 bpm and≥91 bpm) in abstract.②To explore the clinical application of prospectively ECG-gated transverse DSCT coronary angiography.Methods Two hundreds patients[Body mass index:23-25 kg/m~2,122 patients(average HR≤75 bpm),78 patients(average HR≥91 bpm)]with suspected or known coronary artery disease underwent prospectively ECG-gated transverse DSCT coronary angiography,among them,30 patients underwent selectively coronary angiography,grouping them into 2 groups according to the average HR of scanning.Group A(17 cases,HR≤75 bpm),group B(13 cases, HR≥91 bpm),the DSCTA results were compared with SCAG.Then,calculate the accuracy of patients in each group and evaluate the agreement of accuracy between DSCTCA and SCAG by Kappa statistics.

A coronary microthromhoembolism model was successfully established by injecting sodium laurate into the coronary arteries. Coronary micro-thrombogenesis may promote the apoptosis of cardiomyocytes, and is one of the reason for heart function decrease. Telmisartan can efficiently suppress ventricles reconstruction, improve heart function, and inhibit the apoptosis of myocardial cells after microthrombogenesis in coronary artery.
