肺动脉

These results indicated: the disbalance between cell proliferation and apoptosis which might is induced by c-myc, bcl-2 and p53 might contribute to PVSR.

以上结果显示，可能由于c-myc、bcl-2、p53基因表达异常导致的细胞增殖、凋亡失衡参与了COPD合并肺动脉高压的进程。

Mean pulmonary artery pressure was 40+/-9 mmHg, cardiac index 2.5+/-0.7 L x min(-1) x m(-2) and pulmonary vascular resistance 521+/-205 dyn x s x cm(-5). 1-yr survival was 60%.

平均肺动脉压为40+/-9mmHg，心脏指数2.5+/-0.7L×min（-1）×m（-2）和肺血管阻力521+/-205 dyn×s×cm（-5）。1年生存率为60％。

METHODS From October 2004 to January 2008, 24 patients with complex congenital heart disease underwent RHB. The dignoses of patients included tricuspid atresia, single ventricle, and so on. Among them, 8 cases were found ectopia cordis. Opreation precedure included bidrectional Glenn shunt (19 cases) and total caval pulmonary connection (TCPC,5 cases). In the 24 cases, 16 patient underwent off-pump operation. RESULTS Total hospital mottality was 4.2%.

2004年10月至2008年1月，采用右心旁路手术治疗复杂先天性心脏病共24例（病种包括三尖瓣闭锁、单心室等，其中心脏位置异常8例）。19例行双向格林术，5例行全腔静脉-肺动脉吻合术。24中16例在非体外循环下实施，2例双向格林术术后再次手术。

According to the echocardiography,enlarged internal diameter of left ventricle was found in 8 patients and short-axis fractional shortening of left ventricle 5% in 3 patients.Six out of the above 8 patients presented with shortening of accerlerating time,decreasing of accerlerating time/right ventricular ejective time value and moving forward of spectral peak in different degrees.All patients were given antianginal drugs such as β-recepter blockers,nitrate preparations and part by angiotensin converting enzyme inhibitor,diuretics and digoxin,The illncss of 29 patients were gradually controlled within one week.Three patients with AD were complicated by acute left heart failure.No obvious changes in FS of left ventricle were found on echocardiography by bed.

测量肺动脉瓣口血流频谱，左心室内径增大的8例中有6例出现不同程度的血流加速时间缩短，血流加速时间/右心室射血时间比值减小，频谱峰值前移。31例均给予β受体阻滞剂、硝酸酯类等抗心绞痛治疗，部分给予血管紧张素转换酶抑制剂、利尿剂和地高辛，其中29例在1周内卧位型心绞痛逐步得到控制。3例卧位型心绞痛发作时合并急性左心衰竭者，在床旁观察超声心动图，发现左心室短轴缩短率无显著变化，给予利尿剂、减轻前后负荷等治疗，急性左心衰竭得以纠正。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
