objective trimetazidine has shown anti-ischemic properties to improve exercise tolerance without haemodynamic effects and direct cyto protective effect on the myocardium.however,it is not clear whether trimetazidine has beneficially effect on severe ischemic cardiomyopathy.methods 19patients（68±9）years with postnecrotic left ventricular dysfunction（ejection fraction31.7%±5.4%）were studied to examine the benefit of adding60mg a day of trimetazidine for3months to the classical therapy.the assessment included clinical evaluation,electrocardiography and echocardiography.results after adding60mg a day of trimetazidine for3months,attack of angina was relieved and dyspnea was improved（p.05）.but heart rate,systolic blood pressure,rate pressure product,ejection fraction,left ventricular volume and global wall motion index were not changed.conclusion trimetazidine seems to improve clinical status while can not change oxygen supply-to-demand ratio without adverse effects in patients on severe ischemic carˉdiomyopathy.

目的 曲美他嗪是一种新型的抗心肌缺血的药物，能够改善患者的运动耐量和心肌的直接保护作用同时并没有血流动力学效应。但目前对于严重缺血性心肌病患者的临床治疗价值还需要进一步观察。方法 19例（68±9）岁确诊为缺血性心肌病（左心室射血分数0%）的患者在常规治疗的基础上加用每日60mg曲美他嗪治疗3个月，随诊观察患者临床情况以及超声心动图指标的变化。结果 19例患者均可耐受在常规治疗基础上加用每日60mg曲美他嗪的治疗，随诊发现患者心绞痛发作明显减少，运动耐量明显改善。同时患者心率、收缩压、心率血压乘积、左心室射血分数、左心室容量以及整体室壁运动指数无明显改变。结论缺血性心肌病的患者在常规治疗基础上加用曲美他嗪是安全的，同时其能明显改善患者的临床状态，而这种作用并不改变心肌氧的供求比值。

AbstractAIM: To investigate the changes of postocular vascular hemodynamics of patients with diabetic retinopathy.

目的：观察糖尿病视网膜病变(diabetic retinopathy，DR)患者球后血管血流动力学的变化情况。

Methods:The "recuperating-sight" exercise was compiled from the ability of "seeing all directions" and contrasted with caring-sight exercise in aspects of near sight improvement and postocular hemodynamics.

Results: Successful reopening of the vessels was obtained in both patients without the evidence of postsurgical ischemic event.

结果表明，在动脉切开术期间，如果手术前的血管造影提示是颈动脉分叉远侧的血管阻塞显明，并能通过ICA获得黑质返流的血流，那么直接颈动脉内膜切除术可以安全地执行。

By using β-NADPH-diaphorase histochemical staining technique,wefound for the first time that NOS activity was detected in the epithelium of airpathway and endothelium of vessels but was not detected in the small vessels(ID＜100μm),and the NOS express in pulmonary vascular endothelium of preascitic andascitic broilers were elevated,especially in the endothelium and smooth muscle layer ofsmall vesseles with thicker walls and of muscularized nomuscular artery in asciticbroilers.

本研究从田间自然发生腹水症的肉鸡群中选取正常肉鸡、亚临床腹水鸡和腹水鸡为实验对象，通过比较这三种肉鸡血流动力学、心电图、动静脉血血气、肺外动脉舒张反应性、肺血管结构以及肺组织一氧化氮合酶的活性和分布等方面的不同，探讨了肺动脉舒张能力在肉鸡肺动脉高压形成中的作用和机制。

A significant negative linear correlation between clonidine concentration and rCBF or spindle activity was observed in the thalamus, prefrontal, orbital and parietal association cortex, posterior cingulate cortex, and precuneus.

统计学分析后，发现在丘脑区、前额叶、眶上回及顶叶联合脑区大脑皮质、背扣带回大脑皮质、楔前叶，可乐定浓度与区域脑血流（ rCBF ，即脑电图出现梭形波）呈统计学意义的负线性相关关系。

Propofol were used by target controlled infusion method in all patients during induction.The changes of MAP、HR were recorded at preinduction、 preintubation、intubation and post-intubation 1,3,5 minuters.

观察诱导前、气管插管前、插管时及插管后1、3、5min等6个时点的血流动力学参数值变化，并记录各组气管插管诱导应用异丙酚的总量。

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

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。
