肺动脉

Pulmonary hypertension, hypoplasia of pulmonary artery, myocardiac strain and the residual lesions were the major risk factors of surgical management of C-CHD in this series.

肺动脉高压、肺血管发育不良、房室瓣返流和心肌损伤是外科治疗复杂先心病的四大危险因素。

In light of the literatures in the recent years on anoxic pulmonary hypertension treated by Chinese medicine,Chinese medicine had selective hypotensive effect on pulmonary circulation and little effect on systemic circulation,consequently resulted in positive cardiac myodynamia and did no harm to blood gas.Thus Chinese medicine had better applied prospect and potential developmental value.

从近年来中医药治疗缺氧性肺动脉高压的文献报道看，中医药对肺循环有选择性降压作用，对体循环的影响较小，有正性心脏肌力作用，对血气无不利影响，中医中药有较好的应用前景和潜在的开发价值。

In the parasternal four chamber view or the main artery of the short axis view,Continuous Doppler spectrum showed tricuspid regurgitation,Measurement of the maximum tricuspid regurgitation velocity,Used to estimate the maximum pulmonary artery systolic pressure.

在胸骨旁四腔切面或大动脉短轴切面，应用连续多普勒显示三尖瓣返流频谱，测量三尖瓣最大返流速度，用以估测最大肺动脉收缩压。

TBS had obvious image features on CDE:① The parasternal long axis view of two-dimensional echocardiography （2DE） image showed discontinuous echo of ventricular septal,and the anterior aorta developed from right ventricle while the posterior pulmonary artery straddled on the ventricular septal, which was named 2DE ＂straddle sign＂.

TBS的CDE图像特征：①二维超声心动图（2DE）胸骨旁左室长轴观显示室间隔回声中断，主动脉在前方发自右心室，肺动脉在后方骑跨在室间隔之上，称2DE&骑跨征&。

OBJECTIVE To analyze pathoanatomy and modus operandi of 47 patients with Double Outlet Right Ventricle, and evaluate individual operation design of DORV.METHODS47 patients (31male, 16 female) aged from 2 to 26 (mean 13.6±12.1) with DORV were operated from Jan 1997 to Jan 2006, 46 of these patients had pulmonary artery stenosis.

诊断为单纯DORV者36例，DORV合并镜面右位心、内脏转位5例，1例合并下腔静脉闭锁、左上腔静脉畸形引流及无顶冠状静脉窦畸形，2例Taussing-Bing心脏畸形，2例伴有完全型房室隔缺损（其中1例伴有大血管转位），46例患者均伴有肺动脉狭窄，临床表现为紫绀和杵状指。

32 Patients over 50 years old (range 50～63) received surgical treatment.concomitant cardiac anomalys:tricuspid regurgitation in 18 patients,mitral valve regurgitation in 8,atrial tibrillation in 6,CAD in 2.preoperative ment pulmonary arterypressure Was(40.98±8.52)mmHg.All of the patients underwent Dacron or pericardia patch,18 TVR and 6 MVR,2MVP,2 patients with artrial fibrillation underwent right sided maze pricdure,and 2,CABG.

其中合并三尖瓣中重度返流18例、二尖瓣关闭不全8例、房颤6例、冠心病2例；肺动脉平均压力49.08±8.52，最高65mmHg；心功能三级10例、四级2例，采用心包补片或涤纶补片补缺损，同期行三尖瓣成形18例、二尖瓣成形术6例、二尖瓣置换术2例、右房迷宫术2例、冠状动脉搭桥术2例。

Objective To optimize the conditions for the extraction of roots of Peucedanum praeruptorum Dunn.

摘要摘要：目的为合理提取白花前胡中降肺动脉高压的活性成分提供实验依据。

Results In the 24 patients pulmonary embolism,there were 12 cases complicated with phlebothrombosis of lower limbs and 6 cases suffered from chronic cardiac and cerebral diseases,2 patients with long-term-bed-lay because of operation or trauma.

结果 24例肺动脉栓塞患者，既往有下肢深静脉血栓形成史12例，慢性心脑疾病史6例，手术、外伤或长期卧床史2例。

At present, the diagnosis pulmonary embolism method has very much, like the pulmonary artery radiography, spiral CT, the magnetic resonance imagery, as well as to doubts examines carries on the strict medical history collection and the electrocardiogram, X sternum inspection for the deep phlebothrombosis pulmonary embolism patient, the clinical symptom, the body draft and correlation diagnosis pulmonary embolism the and so on change method.

目前，诊断肺栓塞的手段有很多，如肺动脉造影、螺旋CT、磁共振成像，以及对疑诊为深静脉血栓形成肺栓塞的病人进行严密的病史收集和心电图、X线胸片检查，临床症状、体征及相关的变化等诊断肺栓塞的方法。

objective to study the changes of t-pa and t-pa inhibitorduring the acute stage of cor pulmonale.methods to measure the plasmatic activity of t-pa and pai by chrom-substrate in60cases of cor pulmonale,compared with the corresponding index of55cases in the control group.results pai was significantly higher in acute stage than in remission stage of corpulmonale,and t-pa was lower in remission stage than in acute stage.the difference was significant（p.01）.conclusion the unbalance between t-pa and pai can promote the formation of micro-thrombus and further exacerbate high pulmonary pressure.

目的 探讨血浆组织型纤溶酶原激活物及t-pa抑制物在肺心病急性加重期的变化。方法用发色底物法测定60例肺心病急性加重期的血浆t-pa及pai的活性，并与对照组55例肺心病缓解期的相应指标作比较。结果肺心病急性加重期患者pai显著高于肺心病缓解期，而t-pa低于肺心病缓解期，其差异具有非常显著性（p.01）。结论 t-pa及pai关系失衡，有助于动脉内微血栓形成，促进或加重肺动脉高压的形成。

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。
