查询词典 cardiac disease

Methods The cardiac myocytes model of myocardial ischemia reperfusion injury was induced with sodium dithionite (Na2S2O4). The primary cultured cardiac myocytes of SD neonatal rats were randomized into six groups: normal group, model control group, high-dose β-asarone (25 μg/mL), middle-dose β-asarone group (12.5 μg/mL), low-dose β-asarone group (6.25 μg/mL) and medium group.

采用连二亚硫酸钠(Na2S2O4)建立心肌细胞MIRI模型，将原代培养的SD大鼠乳鼠心肌细胞分6组：正常对照组、MIRI模型组、β-细辛醚高、中、低剂量组(25， 12.5， 6.25μg/mL)、基质组。

BNP level is an effective way to identify cardiac and non-cardiac dyspnea.

BNP水平高低是鉴别心源性和非心源性呼吸困难可靠的指标。

Cardiac electricity mapping is an very important method in study of cardiac electrophysiology and clinic diagnoses or treatment of arrhythmia.

心电标测是心脏电生理机理研究的主要方法，也是临床诊断和治疗心律失常的重要手段。

But in SD rats, cardiac muscle fibers were fractured seriouly , contracted to wavilness obviously, then muscle fibers fracture were contracted like entasia by the hypoxia time increased , injury intensify , all the changes refered SD rats compensatory mechanism can not be transferred in this hypoxia degree. 3. Exposed to 4% oxygen concentration, the cardiac muscle ultrastructure of Gansu zokors had serious injury after hypoxia 2h.

在4%氧浓度的低氧耐受实验中，甘肃鼢鼠在低氧2，4h后，心肌纤维收缩明显呈波浪状，低氧时间延长至6，8和10h后，心肌显微波浪状收缩由强逐渐变弱，并逐渐恢复至正常状态，说明鼢鼠心肌在6h以后对严重缺氧环境开始代偿性适应；SD大鼠2h组心肌纤维断裂严重，收缩加强成明显的波浪状，随着低氧时间得增加，4h组呈严重成挛状收缩，损伤加剧，提示SD大鼠在这一氧浓度下已经无法正常调动其代偿机制。3。

First of all, examination and evaluation of cardiac functions were carried under rest condition of subjects for excluding definite cardiac diseases.

其次进行运动负荷的检查与评定，发现早期心脏疾病，挑选优良的泵血功能者。

Cardiac murmur can be easily heard in the patients with normal cardiac function, fast regurgitant velocity, thin chest wall and excursive regurgitation jets.

心功能低下、返流速度缓慢、胸壁厚、血流方向居中者不易闻及二尖瓣收缩期返流性杂音。

In patients with biopsy-proven cardiac amyloidosis, late gadolinium enhancement frequently occurs in a peculiar pattern. On the basis of the gold standard, EMB, noninvasive CMRI can be used to diagnose or rule out cardiac amyloidosis with good sensitivity and excellent specificity in a clinical routine setting.

在心肌活检证实为淀粉样变性的患者中，钆延迟增强扫描常常会以特异的方式出现，在此金标准基础上，EMB和非侵入性CMRI可用于诊断或排除心肌淀粉样变性，仅有较高的敏感性和优越的特异性。

The resuscitation team leader should consider the need for an emergency hysterotomy protocol as soon as a pregnant woman develops cardiac arrest.4,16–18 The best survival rate for infants ≥24 to 25 weeks in gestation occurs when the delivery of the infant occurs no more than 5 minutes after the mother's heart stops beating.16,19–21 This typically requires that the provider begin the hysterotomy about 4 minutes after cardiac arrest.

一旦孕妇发生心跳停止，复苏组领导应该考虑到是否有必要行急诊剖宫产[4，16–18]。孕24～25周以上婴儿最高存活率发生在对心跳停止不超过5分钟并施行分娩手术的的孕妇上[16，19–21]。这就要求医务人员在心跳停止4分钟就开始行剖宫产。

Kuwahara Koichiro, Saito Yoshihiko, Hardda Masaki, et al.Involvement of cardiotrophin1 in cardiac myocytenonmyocyte interactions during hypertrophy of rat cardiac myocyles in vitro.

本实验结果显示，在培养新生大鼠心脏CFs中，AngⅡ能明显增加CFs培养液胶原含量，且具有明显的剂量依赖性，表明AngⅡ可促进心脏ECM沉积。

It is a forward and important subject in world . Echocardiography is a maturate, cheap and easy repeating technique in assessment of cardiac function. Therefore we added to estimateing cardiac global and local function with echocardiography in ischemic dogs.

晚近研究表明，骨髓干细胞具有修复心脏损伤的功能，它已成为国外研究的前沿和热点，超声心动图是评价左心功能的较为成熟、价廉和易重复的技术，因此我们增加了利用超声心动图评价骨髓干细胞移移植对缺血犬心脏整体和局部心功能的影响。

Finally it offers the analysis of the fault-tolerance system as well as its test verification.

这样，运行于空间环境中的系统的设计目标就是在保证系统实时性

However, it is still difficult to find out the real reason of the increase of the keratinized gingiva during the orthodontic extrusion whether it is due to the proliferation of the gingival tissue or to its elastic nature, that is because the proliferation of the fibroblasts as well as the connective tissue changes in volume and the intra-fibers spaces were all immeasurable in most of the studies.

然而，仍然难以找到真正的原因增加的角化牙龈在正畸挤压它是否是由于扩散的牙龈组织或其弹性性质，这是因为增殖的成纤维细胞以及作为结缔组织的变化量和内部纤维空格都是不可估量的，大多数的研究。
