经耐疲劳训练的自体骨骼肌，内衬自体心包制成骨骼肌心室，并以同种带瓣主动脉吻合于右心房或上、下腔静脉与肺动脉之间来代替或辅助右心室的功能，可提高肺动脉收缩压及肺动脉血流并使之成为波动性，而且具有不需抗凝，无血栓形成等优点。

Objective To investigate the effects of the Nω-nitro-L-arginine methyl ester on pulmonary artery of rats during 14 days simulated weightlessness.

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。

These results suggest that ONOO- causes weak relaxation in pulmonary artery, which is down regulated by endothelium and is of tachyphylaxis.

结果表明， ONOO-对肺动脉的舒张作用较弱，此作用受到内皮细胞的抑制性调节并有快速去敏性。

The results showed that (1) all the arteries tested had tachyphylaxis to peptidergic agonists;(2) the desensitization of the arteries tested to catecholamines was uneasy except BA;(3) the desensitizations to AⅡ, AVP and PE were homologous;(4) the endothelium-EDRF -cGMP pathway had no contribution to the tachyphylaxis of PA to AⅡ and AVP;(5) membrane receptor cycling (internaliation and re-insertion) contributed only in part to homologous desensitization;(6) there was no change in the function of voltage-dependent Ca〓 channel during desensitization to AⅡ and AVP;(7) some changes in G protein occurred during homologous desensitization;(8) the most surprising finding was that the caudal arterial smooth muscle of stroke-prone spontaneously hypertensive rat showed tachyphylaxis to α〓-adrenoceptor agonist PE, while the tachyphylaxis of pulmonary artery of SHR was not changed compared with that of Wistar rat.

脱敏是消除效应的一种有效方式。因此，研究不同血管对不同激动剂脱敏的差异及阐明脱敏的机制，有助于阐明血管活动个性化的机制。研究表明：血管对肽类激动剂的脱敏方式为快速脱敏，而对儿茶酚胺类激动剂不易脱敏；血管对肽类激动剂和儿茶酚胺类激动剂表现为同源脱敏；内皮-NO-cGMP通路不参与肺动脉对AⅡ和AVP的快速脱敏；用PAO抑制膜受体的内在化只能短暂抑制脱敏的发展，提示用膜受体数目的下调说不能完全解释同源脱敏；血管对AⅡ和AVP脱敏后VSMC细胞膜电压依赖性钙通道功能无改变；CA对AVP脱敏后GTPγS的量-效曲线下移，说明有G蛋白的变化，但这种变化并非G蛋白的亲和性改变；SHRsp之CA平滑肌对AⅡ和AVP的快速脱敏并未减弱，但对PE却表现为快速脱敏，这是我们首次发现的一个非常有趣的现象。

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。
