However, when AV interval was shorter than 80 msec and longer than 180msec, there was reduction of LVOTG, yet the CO was also reduced. The results showed that the hemodynamic improvement must depended on the state of pre-excitation of ventricle as well as the optimal left ventricular filling.

且在AV间期为100至120毫秒时出现最佳血液动力学效应，而AV间期在小于80毫秒、大于180毫秒时，虽有左室流出道压力阶差的降低，但心输出量均有下降，提示血液动力学的改善必须依赖右心室的提前激动状态及最佳的左心室充盈。

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。

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。

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.
