查询词典 cardiac

BACKGROUND: Protein kinase A signaling has long been known to play an important role in cardiac function. Dysregulation of the protein kinase A system, caused by mutation of the protein kinase A regulatory subunit gene PRKAR1A, causes the inherited tumor syndrome Carney complex, which includes cardiac myxomas as one of its cardinal features.

背景：长期以来，蛋白激酶A信号途径被认为在心功能中起着重要作用，蛋白激酶A调节亚单位基因PRKAR1A的突变导致蛋白激酶A系统失调，引起遗传性肿瘤综合征－Carney合成，其中心脏粘液瘤作为其主要特征。

However, data on the cardiac synchronicity and cardiac function are scarce for subjects with isolated bundle branch block.

目的 应用常规超声心动图和无创的超声诊断新技术—组织多普勒，评价孤立性束支阻滞者的心脏运动同步性和心功能，以及同步性与QRS时限的关系。

Methods 102 patients with severe bradycardia were divided into two groups. 48 patients were given floating catheter transvenously for temporary cardiac pacing at bedside, while 54 patients were given regular transvenous cardiac pacing under X-ray direction. Operation achievement ratio, operation time, pacing parameter and complication incidence were observed in both groups.

102例严重心动过缓的患者，48例行床旁紧急置入漂浮电极导管进行心脏临时起搏，54例经X线透视下置入普通电极导管进行心脏临时起搏，对比观察两组手术成功率、手术耗时、起搏参数及并发症。

Additionally, the rapid cardiac hypertrophy induced by experimental complete coarctation was accompanied by a disproportionate increase in COX activity, which was suggested to maintain the cardiac energy-producing capacity in overloaded hearts.

腹动脉完全结扎造成心脏快速肥大的模式中，COX之活性上升，可能是用来供应心脏在过度负担时所需之额外能量。

Shone's syndrome is a rare congenital cardiac condition thatconsists of up to four obstructive left-sided cardiac lesions.

Shone's 综合征是一种罕见的先天性心脏病，主要包含多达4种左心的梗阻性损伤。

Mid-thoracic anesthesia or associated with general anesthesia can influence cardiac autonomic nerve tension,with principal manifes tation of decrease reflecting cardiac sympathetic nerve LF value.

结果：E组病人硬膜外麻醉后LF、HF、LF+HF值均较基础值下降P 1后均较T0有所下降，以T3下降明显(P1后均较T0明显下降P1后各时段值均较T0值下降，以T2后明显(P1后各时段值均比A组相同时段值低P结论：中胸段硬膜外麻醉或复合全身麻醉均可影响心脏自主神经的张力，并且主要表现在反映心脏交感神经的LF值降低。

The response of GFAP positive-astrocytes peaked at 24 h, and then decreased. Conclusions Neurons and astrocytes in Nucleus Tractus Solitarii were activated sequently after acute cardiac injury, which suggested that the involvement neurons and astrocytes of NTS in the central modulation of cardiac pain after ACI.

急性心肌损伤后，大鼠延髓NTS中神经元和星形胶质细胞被心肌伤害性刺激激活，参与心肌损伤后疼痛的中枢调控。

Abstract］ Objective To discuss early cardiac cancer's X-ray performance,enhance the understanding of this sick.Methods After surgery and pathology confirmation 28 examples of early cardiac cancer X-ray performance were analyzed.

目的 探讨早期贲门癌的X线表现，提高对本病的认识方法回顾性分析经手术及病理证实的28例早期贲门癌患者的X线表现。

In order to study the architectuer of human cardiac neurons, the location and mumber of human cardiac ganglionated plexuses and their nervous connections were investigated.

为了研究人心脏神经元的构筑，观察了人心脏神经节的分布数量和神经连接。光镜下发现大量神经节（550±149）或神经元分布在人的心房和心室表面。

ObjectiveThe sinus node artery is the only blood supply for the sinus node, and cardiac arrhythmia is common when the artery is involved in coronary artery diseases or in heart surgeries. Thus its important for selective coronary angiographies and cardiac surgeries to make clear the form and course of the sinus node artery.

目的 窦房结动脉(sinus node artery，SNA)是窦房结的唯一血供来源，当冠心病或心脏手术累及该动脉时都可导致窦房结缺血而发生各种心律失常，所以对窦房结动脉的形态及走行的认识在选择性冠脉造影和心脏外科手术等方面都具有重要意义。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
