On the other hand, we took 7 patients with severe bicuspid valve disease and heart failure into group B1, all these pati...

同期收治风湿性二尖瓣疾病合并全心衰竭患者7 例分为B1组，于二尖瓣置换术中经左、右冠状动脉及心肌内注射干细胞悬液。

The valve replacement with partly or whole mitral valve structure can improve the ventricular internal diameter, ejection fraction, cardiac index and stroke volume, thus improving cardiac function. However, bicuspid valve restenosis should be avoided through active observation.

保留部分或全部二尖瓣结构的瓣膜置换能更好地改善左心室内径大小、射血分数、心指数、每搏输出量，从而改善心脏功能，但要积极观察以避免出现二尖瓣再狭窄。

Especially the formation of reversal gradient of blood pressure before the dicrotic notch.

特别是逆向血压梯度的形成，认为动脉血流的惯性及左心室的舒张是重搏波切迹前短时期内近心端血压低于远心端血压的主要原因，在动脉中存在着惯性动能与压力势能之间的相互转化。

BACKGROUND: Levosimendan is a novel drug used for inotropic support in heart failure, but its efficacy in local anesthetic-induced myocardial depression is not known.

背景：左西孟旦是一种作用於心衰的新型强心药，但其对於局麻药导致的心肌抑制作用尚未知。

One example of a new generation LVAD is HeartWare's intrapericardial HVAD. This miniaturized centrifugal pump is capable of generating up to 10 L/min of flow. Its wearless impeller is suspended in the pump housing through a combination of passive magnets and hydrodynamic thrust bearing.

新一代左室辅助装置的安全性能有了明显的提高，研究者试图将其应用于非终末期心衰的患者，以延长这部分患者的长期生存率，这是心衰器械治疗专题会带给我们的信息。

After administration of L-N〓-nitro-Arginine, a specific antagonist of NOS, it was found that the basal and stimulated NO release of blood vessels (aorta, internal carotid, renal and mensenteric artery) was decreased further. The increase of coronary blood flow stimulated by Ach was also reduced further, while the platelet aggregation degree and erythrocyte aggregation index increased significantly. Pathological examination indicated that aortic endothelium was destroyed, the blood vessels in cerebral, cardiac and renal tissues were hypertrophied further and some were almost occluded. The above fin dings resulted in SHR feeded with L-NNA having high incidence of stroke rate and high degree of renal cirrhosis when compared to control SHR. The infarct and hemorrhagic focuci in cerebral tissues, infarct focuci in cardiac tissues, atrophy and hyalinedegeneration of renal glomeruli and degeneration even necrosis of renal tubuli in renal tissues were al so found. The increase ratio of brain and heart to body weight and decrease ratio of kidney to body wei ght further demonstrated that the cerebral, cardiac and renal injuries were aggravated.

在上述结果的基础上进一步给予SHR NOS特异性拮抗剂左旋亚硝基精氨酸后，血管(胸主、颈内、肾及肠系膜动脉)NO基础释放及激动剂刺激释放进一步减少，Ach刺激冠脉流量的增加和胸主动脉内膜NOS活性也进一步减少，血小板聚集程度及红细胞聚集指数显著上升，病理切片显示胸主动脉内皮细胞破坏明显，脑心肾组织内的血管进一步增厚甚至几乎阻塞，导致饲L-NNA的SHR缺血性及出血性脑卒中发生率显著高于对照SHR，脑体重比显著升高；心肌内出现明显的缺血梗塞疤痕灶，心体重比显著升高；肾小球明显萎缩、玻璃样变性，肾小管也变性甚至坏死，使肾硬化程度显著增加呈颗粒性固缩肾，肾体重比也显著减少。

The heart of the wise inclines to the right, but the heart of the fool to the left.

智慧人的心居右。愚昧人的心居左。

A wise man's heart inclines to his right, but a fool's heart inclines to his left.

10：2 智慧人的心偏右；愚昧人的心偏左。

Methods A rabbit model of myocardial ischemia and reperfusion was established by ligating the anterior descending coronary artery.

采用结扎新西兰兔左冠状动脉前降支的方法制备缺血再灌注动物模型，用电磁血流量计测量心输出量，应用美国物理学会出版的Choas Data Analyzer 软件对所采集的HRV 进行非线性动力学分析，并与心排血量比较，分析其相关性。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.
