Measurirg indxes included:(1) Electrocardiograh;(2) Hemodynamics: cardiac output, pump output, aortic pressire, pulmo nary artery pressure, left atrium pressure, right atrium pressure, left ventricular end systolic pressure, left ventricular end diastolic pressure, LV-dp/dt, right ventricul ar end systolic pressure, RV-dp/dt, systolic pressure time index, diastolic pressure time index, endocardial viability ratio;(3) Myocardial metabolism: coronory sinus blood flow, myocardial oxygen consumption, myocardial lactate extractiorn;(4) Ischemic myocardial area;(5) Ultrastructure of myocardium.

测量指标包括：①心电图；②血流动力学：心输出量、泵输出量、主动脉压、肺动脉压、左房压、右房压、左室收缩末压、左室舒张末压、左室压的一阶导数、右室收缩末压、右室压的一阶导数、收缩压力时间指标、舒张压力时间指标、心内膜下心肌供血比率；③心肌代谢；冠状窦血流量、心肌氧耗量、心肌乳酸摄取量；④心肌缺血面积检查及缺血心肌的超微结构观察。

Recently, a complex congenital heart disease in young infants in Beijing Children's Hospital to accept the "one and a half ventricular repair" operation (the child's right ventricular dysplasia, is not able to meet the functions of his heart, and he was part of the right ventricle to the blood to the road directly to the pulmonary artery, the other part to go through the right ventricle), spent a total of more than 60,000 yuan,"PapaS" fast food companies responsible for 4 million yuan before the children have recovered and been discharged.

最近一个复杂先心病小婴儿在北京儿童医院接受了&一个半心室修复&的手术（这个孩子的右心室发育不良，不能够满足他的心脏功能，把他本来到右心室的一部分血改路，直接到肺动脉，另外一部分还要经过右心室），共花费了6万多元，&PapaS&快餐公司担负了4万多元，先该患儿已康复出院。

The fetal hemoglobin level, white-cell count, and platelet count and the use of hydroxyurea therapy were unrelated to pulmonary hypertension.

胎儿血红蛋白水平，白细胞计数和血小板计数以及使用羟基脲治疗与肺动脉高压不相关。

Results:Compared with the normal controls, manifestations of severe right heart failure,well-elevated pulmonary arterial pressure and serious right heart hypertrophywere observed in the pulmonary hypertensive rats 28 days after left lungresection and MCT injection.

结果：与对照组相比，MCT 注射后28 天大鼠出现重度右心衰竭征象，平均肺动脉压、右室肥厚度均明显升高；镜下可见明显肺血管重构，表现为右肺纤维化、肺小动脉内皮和中膜平滑肌层增生、血管密度降低；肺组织中HGF、eNOS 表达明显减少、TGF-β和ET-1 显著升高(P0.05)，这些细胞因子表达量的改变与肺血管重构存在着明显的相关性。

Thirty-day postoperative mortality (24% versus 9%) and the incidence of postoperative pulmonary hypertension (92% versus 20%) were substantially higher in patients with associated medical conditions.

在采取上述医疗措施或伴随疾病的患者中，术后30天死亡率（24% VS 9%）及术后肺动脉高压发生率（92% VS 20%）均明显高于无上述伴随疾病者。

Thirty-day postoperatie mortality (24% ersus 9%) and the incidence of postoperatie pulmonary hypertension (92% ersus 20%) were substantially higher in patients with associated medical conditions.

在采取上述医疗措施或伴随疾病的患者中，术后30天死亡率（24% S 9%）及术后肺动脉高压发生率（92% S 20%）均明显高于无上述伴随疾病者。

Artemisinin drugs in the treatment of pulmonary hypertension and pulmonary fibrosis have potential medicinal value.

青蒿素类药物在治疗肺动脉高压以及肺纤维化方面具有潜在的药用价值。

White flowers salvia; rat; pulmonary arterial hypertension; vascular endothelial growth factor

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。
