心室

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。

Results :We report a case of bronchogenic cyst occurring in the left ventricle of a 2-year-old boy presenting with intermittent precordial pain, although the true diagnosis was missing preoperatively, complete excision of the cyst was achieved via a left anterolateral thoracotomy.

结果：1例罕见的左心室壁先天性支气管囊肿，术前未获明确诊断，但经左前外侧切口进行了完整切除，病理检查提示囊肿内壁通常由假复层柱状纤毛上皮覆盖，周围含有软骨和支气管黏膜腺体。

In a well-treated population of stable HF patients, there was no significant effect of tolaptan therapy on L olumes obsered during 1 year of therapy.

在经托伐普坦充分治疗稳定的心力衰竭患者，经过一年的治疗，未观察到托伐普坦对左心室容量有明显的作用。

Objective: To evaluate left ventricular diastolic function by velocity vector imaging in patients with hypertrophic cardiomyopathy.

目的：应用组织向量成像技术定量评价肥厚型心肌病左心室心肌舒张顺序。

Results A closure of the mitral and tricuspid valves with simultaneous opening of the aortic valve occurred exclusively during chest compression, resulting in forward blood flow in the pulmonary and systemic circulation. Peak forward aortic flow at a velocity of 58.8±11.6?cm/s was recorded during the compression phase.

结果 所有的6例病人，胸按压时，二尖瓣和三尖瓣关闭，同时主动脉瓣开放，前向血流自心室进入体循环和肺循环；发生在胸按压时的主动脉瓣峰值前向血流速度为58.8±11.6？

CGRP content in myocardium gradually enhanced from normal group to controls group, and model group's was the highest. We found immunopositive neurons and nerve fibers of nNOS and CGRP by immunochemistry in normal myocardium. They were mainly round-shaped and oval-shaped, also tadpole-shaped、 shuttle-shaped、triangle-shaped、ring-shaped and irregular-shaped. Nv of neurons and nerve fibers in atria were more than in ventricle in some degree; Those in right part of heart were more than in left. Morphology of CGRP neurons changed in model group, the number of ring-shaped neurons increasing, while the round-shaped and oval-shaped decreasing, and Nv and Sv of model group were markedly less than normal. Expression of nNOS mRNA was overly higher than normal group, but CGRP was opposite.

心肌组织CGRP的含量由正常组、实验对照组至CHF组逐渐升高，差异显著；免疫组化研究表明心肌组织中存在nNOS和CGRP免疫阳性神经细胞及纤维，细胞形态多样，正常多以圆形和椭圆形为主，还有梭形、蝌蚪形、三角形、指环形及不规则形，细胞密度心房高于心室，右心高于左心；CHF组CGRP神经细胞形态有一定改变，淡染的指环形细胞增多，而深染圆形或椭圆形细胞减少，其面、数密度均明显低于正常组，差异显著；用RT-PCR测得CHF组nNOS mRNA极度表达，显著高于正常组，而CGRP表达明显低于正常组。

Finally, we simulated the 12-lead ECG and some parametersto describe the motion and deformation of ventricular wall, such as displacement, strain, torsion angle and so on.

我们采用了位移、应变、扭转角度等参数来描述心室壁的运动变形情况。

Methods: Twenty-four male SD rats were randomly divided into normal control (NC, n=6), protein C activator (PCA, n=6), lipopolysaccharide (LPS, n=6) and LPS+PCA group (n=6). NC group were given normal saline and PCA group were injected protein C activator (0.4 mg/kg) through vein of the tail. LPS group were administered lipopolysaccharide (10 mg/kg, 4h) by intraperitoneal injection method to make the model of septic shock rats. After the animal model was made, LPS+PCA group were injected protein C activator (0.4 mg/kg) through vein of the tail. 30 minutes after the injection, each rat was tested by Medlab biosignal analyzing system for observing mean arterial pressure and left ventricle function, the activity of LDH and iNOS in myocardium and the cuttings of myocardial tissues.

取SD雄性大鼠24只随机分成对照组、PCA组、LPS组和LPS+PCA组四组，对照组尾静脉注射生理盐水，PCA组尾静脉注射蝮蛇毒蛋白C激活物，LPS组腹腔注射LPS (10 mg/kg， 4h)的方法建立败血症休克的实验动物模型，在建立败血症的实验动物模型的基础上，尾静脉注射PCA (0.4 mg/kg)为LPS+PCA组，每只大鼠均于药后30 min时运用Medlab生物信号采集处理系统记录平均动脉压和左心室功能指标，并测定心肌中乳酸脱氢酶活性、诱导性一氧化氮合酶活性及心肌病理切片。

Five different kinds of dynamic modes are found corresponding five regions in parameter space. In the region Ⅳ, the stable resting stable and stable limited circle of oscillation coexist.

通过改变描述心室肌细胞动作电位动力学的Beeler-Reuter方程的慢离子电导Gs和漏电流I，研究了Gs～Ⅰ平面上参数点对应的系统动力学模式和稳定吸引子性质。

Background— The INTRINSIC R (Inhibition of Unnecessary R Pacing with ASH in ICDs) study tested the hypothesis that dual-chamber rate-responsie with atrioentricular search hysteresis 60-130 programming is not inferior to single-chamber–40 programming in an implantable cardioerter defibrillator with respect to all-cause mortality and heart failure hospitalizations using an equialence margin of 5%.

背景： INTRINSIC R（ICD非必要右室起搏及房室搜索延迟）研究证实用5%的等效界值计算，就全因死亡率和心衰恶化住院而言，ICD双腔起搏频率应答模式加上房室搜索延迟模式，频率60~130 bpm，不劣于单独心室节律支持模式，频率40 bpm。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""
