The relationship between the cardiotonic effects and the cardiac sarcolenmmal Na〓, K〓-ATPase activities by strophanthidin in isolated guinea-pig heart

本研究通过对正常和衰竭的离体豚鼠心脏和急性分离的心室肌细胞的研究，在器官水平分析了毒毛旋花子苷原的强心作用及其与Na〓，K〓-ATP酶活性间的关系，在细胞水平分析了毒毛旋花子苷原提高心肌收缩力的可能机制。

Among of these, the research of TEHV has taken positive progress,but the research of EHT just started recently ,it is still facing a series of problem.At first,it is the selection of planting cells,how to take high degree of purity about cardiomyocytes should be overcome;Second,it is the selection of scaffolds,the biomechanical properties of scaffold been used still can,t meet the requirement.

首先是种子细胞的选择，如何获取纯度较高的心肌细胞，还需从各种种子细胞中进行筛选；其次是支架材料的选择，目前应用的材料在生物力学特性上还不能满足临床使用的要求，还无法承受左心室巨大压力的冲击，因此还有待进一步的研究和改进。

Cardiac surgery in recent years a rapid development of science, some medical workers currently not in time to catch up with this new trend, so do not know much about the current level of cardiac surgery, some patients do not know when to be in a small treatment For example, ventricular septal defect, atrial septal defect. 10 years ago, such as textbooks that children speaking a bit more, to 5-year-old children re-treatment at the time.

心脏外科是近年来发展较快的一门学科，目前国内有些医务工作者没有及时跟得上这个发展趋势，所以不太了解心脏外科现在的水平，不太知道有些病必须在小的时候治疗，比如心室间隔缺损、房间隔缺损。10年前的教科书上讲的是等孩子大一点，到孩子5岁的时候再治疗。

Under the superfusion of low potassium Tyrode's solution, EAD were relatively easy to occur in both mouse atrial and ventricular fibers, suggesting the close relation between the potassium currents and the generation of EAD.

我室以往的工作表明：小鼠心肌是研究EAD的理想标本。既使轻微的低钾（3mM 〓）条件也足以诱发小鼠心房肌和心室肌的EAD（尽管二者难易度上存在差别），提示小鼠心肌细胞上的钾电流与EAD的发生关系密切。

Role of endothelial function and inflammation in patients with cardiovascular risk factors, with and without a history of myocardial infarction;Comparison of gated blood pool SPECT and multidetector row computed tomography for measurements of left ventricular volumes and ejection fraction in patients with atypical chest pain: Validation with radionuclide ventriculography;Plasma adiponectin, T94G gene polymorphism and PAI-1 in patients with and without hypertension;Prognostic value of myocardial perfusion imaging in symptomatic and asymptomatic patients after percutaneous coronary intervention;Impact of early initiation of intravenous therapy for acute decompeusated heart failure on outcomes in ADHERE……

文章摘要：内皮功能和炎症在有或无心肌梗死病史的具有心血管危险因素患者中的作用；门控血池SPECT和多层螺旋CT对于测量不典型胸痛患者左室容积和射血分数的比较：以放射性核素心室造影检查进行验证；有或无高血压的患者的血浆脂联素、T94G基因多态性和PAI-1；心肌灌注成像对经皮冠状动脉介入后有症状和无症状患者的预后评估价值；ADHERE中早期开始静脉用药治疗急性失代偿性心力衰竭对预后的影响

Since the most significant difference happened between the middle phase of expiration and the middle phase of inspiration, this result implies that it is the intrapulmonary pressure and the cardiac volume, but not the relative position of the heart and electrodes, which cause the variation of the amplitude of QRS complex.

其中QRS波的振幅在呼气中期最高在吸气中期最低，根据呼吸运动时肺容积及肺内压变化的规律，认为是由于胸腔压力和心室舒容积的改变，而不是心脏与电极间的相对位置的改变造成了QRS波振幅的变化。

The index of left ventricle pachynsis was lowered after treatment in both groups. The decrease of that in the treating group and diastolc function mprovement were more obvious (P.01). Conclusion: Bu Shen He Luo Fang has explicit hypotensive effects and it can depress ventricle remodeling.One of the mechanisms,we conjectured,are maybe local externalization of HGF.

&补肾和络&细颗粒剂具有明确的降血压及抑制高血压左室重塑的作用，推测其机制之一是通过改变局部HGF的分泌实现的，即通过促进组织HGF分泌，恢复其自身修复能力而逆转心室重塑，发挥其心血管保护作用；同时改善内皮功能，维护心肌组织与内皮的稳定性。

Methods: The motion of parasternal papillary muscle anterior wall, inferior wall, posterior wall, and lateral wall were detected by 2DE at short axis view of left ventricle before PTCA, 3 d and 1-3 months after PTCA in 33 cases of patients with coronary heart disease, who received PTCA+stent at selected time. Peak systolic velocity of subendocardial, subepicardial and middle layer myocardium, transmural velocity difference of the same segments and Outer lateral mitral valve annulus were also detected at apical 4 chamber view by pulsed wave tissue Doppler imaging.

对33例择期行PTCA+支架术的冠心病患者用HP5500型超声诊断仪，于PTCA术前及术后3d、1-3个月对胸骨旁左心室乳头肌短轴切面的前间壁、下壁、后壁、侧壁行二维超声心动图(2DE)检测各节段的室壁运动情况，用脉冲组织多普勒成像检测上述各节段的内、外膜下及中层心肌的收缩期峰值速度，内外膜下心肌的收缩速度差及心尖四腔观二尖瓣外侧环的收缩期峰值速度。

We can understand the question as in our AV, but scarcely the standing-still and looking sad on the question as in the RV on account of those events of which they had been speaking, disappointed hopes, all the more bitter for the perplexing tidings about the empty Tomb and the absent Body of the Christ.

我们可以理解的问题在我们的AV ，但几乎没有常设-仍然和展望可悲的关于这一问题，在右心室考虑到这些事件，其中，他们已来说，失望，希望，都更痛苦为令人费解的福音有关空墓和缺席机构的基督。

Coculturing of the transfected fibroblasts with neonatal rat ventricular myocyte cultures resulted in a significant reduction (68%) in the spontaneous beating frequency of the cultures compared with baseline values and cocultures seeded with naive fibroblasts.

与基线值和原始的成纤维细胞的再复制相比，乳鼠心室肌细胞培养基里转录的成纤维细胞的再繁殖，导致了培养基里自律性频率的显著下降（68%）。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
