国内外多项前瞻性临床研究均证实，奈西立肽能迅速改善急性心力衰竭患者的血流动力学状况和临床症状，其有效性和安全性明显优于常规静脉制剂。

Objectives:To evaluate the changes of vascular morphology,homodynamic and endothelial function in patients with early-stage type 2 diabetic mellitus(T2DM) by highresolution ultrasonography.

中文摘要目的：评价高分辨率超声在检测初发2型糖尿病(T2DM)患者血管形态学、血流动力学及血管内皮功能改变中的应用价值。

AbstractAIM: To investigate the relationship between young eyes of central retinal artery and the changes in homodynamic and the occurrence of ischemic cerebrovascular disease.

目的：探讨中青年眼动脉(ophthalmic artery，OA)和视网膜中央动脉(central retinal artery，CRA)血流动力学的变化与发生缺血性脑血管病(ischemic cerebrovasctlar disease，ICD)的关系。

To valuate efficacy and the incidence of complication and homodynamic changes in the combined spinal-epidural anesthesia and continuous epidural anesthesia in complete hysterectomy.

目的 比较联合腰麻硬膜外麻醉与单纯硬膜外麻醉在妇科全子宫切除术中的麻醉效果，并发症发生率和血流动力学的影响。

RESULTS The total mortality was 42%, with 36.4% in coronary heart disease patients and 64% in non-coronary heart disease patients (P.05). In patients using IABP preoperatively, the mortality was much lower than that in patients using IABP during or postoperatively (0%, 40%, 50% respectively, P.05). After using IABP, homodynamic data improved and dose of cardiovascular drugs decreased significantly.

结果 本组总病死率42%，其中冠心病患者手术死亡率（36%低于非冠心病者的手术死亡率（64%，P.05）；术前应用IABP患者手术死亡率（0%）明显低于术中（40%）和术后（50%）应用IABP的患者（P.05）；IABP辅助后血流动力学指标明显改善，血管活性药物用量减少。

Methods 24 patients undergoing cardiac operation using CPB were divided into two groups randomly, according to receiving UTI injection or not. Their manifestation of SIRS, index of homodynamic and respiratory function and data of the early recovery were retrospectively analyzed.

体外循环人工心脏瓣膜替换术患者24例，根据是否在术后早期应用UTI随机均衡地分为处理组和对照组，回顾性观察患者全身炎性反应情况、血流动力学、呼吸功能和早期恢复情况。

Methods 80 patients with chf were divided randomly into regular treatment group treated with diuretic+digoxin+acei, and bisoprolol treatment group treated with regular treatment plus bisoprolol. all the patients were followed up for twelve months and observed the changes of homodynamic, internal diameter of left ventricle, lvef and 6-minutes walk test.

80例慢性心力衰竭患者随机分为常规治疗组（利尿剂+地高辛+acei）和比索洛尔治疗组（在常规治疗基础上加用比索洛尔），疗程12个月，观察两组治疗前后血流动力学、心功能分级左心室射血分数、左心室内径及6min步行试验、左心室射血分数、左心室内径的变化。

But PaO2, PaO2/FiO2, Cdyn were increased and Raw decreased significantly after HVHF (P.05). Conclusion HVHF has the characteristics of homodynamic stability and homeostasis, and improvement of oxygenation. Thus the severity of sepsis is reduced and the prognosis is improved.

HVHF能稳定血流动力学，并通过对内环境调节、改善氧合等，从而对多个器官起到支持作用，有益于减轻病情的严重程度及改善预后。

CTPI can evaluate the brain homodynamic of cerebral ischemia-reperfusion animal model in living state as a rapid, accurate, non-invasive method, show the cerebral infarction ischemic region's site, size, extent, and has important clinical value for the ultra-acute cerebral infarction to treatment and review.

第二部分CT灌注成像在超急性脑梗死实验中的诊断价值目的：应用CT灌注成像(CT perfusion imaging ，CTPI)技术，观察大鼠超急性脑梗死不同时间点脑血流动力学变化及半暗带(Ischemic penumbra ，IP)的演变，为临床早期诊断治疗提供依据和指导。

Results We analyzed homodynamic when the patients applied mechanical ventilation for respiratory failure patients of the great ages. 1） When VT was ≥10 ml/kg and PEEP was set at 0～10 cmH2O, or when VT was 6～12 ml/kg and PEEP was 〉10 cmH2O, the respiratory tract produced high peak pressure and the inspiration platform pressure, with which HR and CVP increased, and SBP, DBP, CI and CO decreased.

结果1。高龄患者在VT达≥10ml/kg时，在PEEP设定为0～10cmH2O范围内；或PEEP≥10cmH2O时，VT设定在6～12ml/kg范围内时，均可产生较高的气道峰压和吸气平台压，产生HR和CVP增高，SBP、DBP、CI和CO下降等血流动力学异常。2。

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。
