The results of functional magnetic resonance: N-acetyl-aspartic acid, choline and creatine in left temporal lobe and anterior part of frontal lobe decreased more obviously and regional cerebral blood volume and regional cerebral blood flow in these areas decreased,while average pass time and peak time of the contrast medium in these areas slightly increased as compared with those in the conitralateral areas; fraction of anisotropy values and the tracked fasciculus in left corticospinal tract decreased, and the connecting fibers between Broca and Wernicke areas also decreased as compared with those in the contralateral area.

It can be said thatblood stasis is the main pathology of DN,which is in line with Chinese medicine in "invalidism must accompany with blood stagnation""invalidism develop into collaterals" The view of blood stasis also match the modern medical point of hemodynamics changes and capillaries disease in patients with DN,such as increased hemorheology general index,blood viscosity and lipids, reduced kidney blood flow,platelet aggregation,sclerosis of blood vessels, renal microcirculation disturbance,even hypercoagulability.

可以说，瘀血阻络是糖尿病肾病的主要病机，这既符合于中医"久病必瘀""久病入络"的学术观点，也与现代医学认识的糖尿病肾病患者血液动力学和肾脏微血管病理学实验中，血液流变学的指数普遍升高、血浆粘度增加、血脂增高、肾血流量减少，血小板聚集、血管硬化，肾微循环障碍，甚至出现高凝状态的研究相当吻合。

Prior administration of "Styrax Pill for Coronary Disease" proper (6 components viz., styrax liquidus, Borneolum, Lignum santali, Aristolochia, Olibanum and Cinnabaris) or the mixture of Styrax liquidus, Borneolum, Lignum Santali and Olibanum to mice prolonged the survival time of the animals subjected to low pressure hypoxia. Styrax liquidus and Borneolum administered separately showed the same effect, whereas none of the other four components showed significant protection.

用小鼠耐缺氧试验和麻醉狗冠状窦血流量及心脏动-静脉血氧差(MA-VO_2)的实验研究冠心苏合丸及其成分的作用，发现：(1)冠心苏合丸能延长小鼠耐缺氧的时间；(2)冠心苏合丸能使心肌梗塞狗的CSF回升，减少心率和MA-VO_2，对非心肌梗塞狗不能提高CSF但亦能减少心率和MA-VO_2；(3)在本实验条件下，苏合香脂和冰片似为冠心苏合丸中起作用的两个成分，其余成分如檀香、青木香、乳香或其油均未能证实其效果。

Objective The arteria carotis externa was ligated,and arteria carotis interna was kept opening The left carotid artery was exposed and placed over an ultrasonic flow probe.The brain flow volume was recorded with an ultrasonic volume meter.The pursiness time of mice was observed to evaluate the effect of Erigeron breviscapus pellets on cerebral ischemia.Methods Born's method was used to investigate effects of Erigeron breviscapus pellets on rabbit platelet aggregation induced by adenosine diphosphate,arachidonic acid,and platelet-acti-vating factor,in vitro or in vivo.Antithrombotic effects of Erigeron breviscapus pellets was monitored accord-ing to Peter's method.

目的 应用二道血流速度流量仪超声探头测定鼠颈总动脉以反映云南植物药业有限公司提供的灯盏花颗粒对脑血流量的影响；记录小鼠断头后张口喘气时间，观察灯盏花颗粒的抗脑缺血作用方法采用Born方法测定灯盏花颗粒在体内外对AA、ADP及PAF诱导的家兔血小板聚集功能的影响；运用电刺激大鼠颈动脉血栓形成方法，评价灯盏花颗粒对血栓形成的阻抑作用。

Intervention: Absolute cerebral blood flow, cerebral blood volume, and mean transit time were measured in the thalamus, putamen, and caudate nuclei.

干预：检测了丘脑、苍白球、尾状核的绝对脑血流量，脑血容量，平均通过时间。

Methods Perfusion weighted imaging was performed in 45 cases of cerebral infarction. The sidetoside ratios of regional cerebral blood flow,regional cerebral blood volume and mean transit time were measured at duty lesion of ischemia. The hypoperfused cerebral areas and the stages of ischemia were defined as follows:compensation stage: rCBF was normal, rCBVwas increased, MTT was prolonged;decompensation stage: rCBF was slightly decreased, rCBV was normal or decreased, MTT was prolonged;preinfarction stage: rCBF and rCBV were decreased,MTT was prolonged.

利用磁共振灌注成像技术（perfusion weighted imaging，PWI）对45例缺血性脑血管病患者的责任病灶进行局部脑血流量，局部脑血容量，平均通过时间比值测定，确定低灌注脑区的影像学特点和缺血分期：代偿期（rCBF保持正常，rCBV升高，MTT延长）；失代偿期（rCBF轻度下降，rCBV正常或下降，MTT延长）；梗死前期：（rCBF下降，rCBV下降，MTT延长）。

Methods Twenty patients with SAP underwent HVHF for 72 hours. The ultrafiltrate rate was set at 3000~4000ml/ h and blood flow at 250~300ml/min. The substitute fluid was infused before dilution. Hemofilter was changed every 24 hours.

20例重症急性胰腺炎患者行连续性静脉－静脉HVHF，置换量3000~4000ml/h，均以前稀释方式输入，血流量250~300 ml/min，连续进行72 h以上，每24小时更换一次滤器及血路。

The decrease of brain blood flow is one of the pathological factors that cause VD.

脑血流量下降是引起血管性痴呆的重要病理因素之一，与学习记忆相关的脑区供血不足可以引起学习记忆障碍等痴呆症状的出现。

The contrast material was bolus injected through antecubital vein ,while four layers of dynamic scans were performed for 50 seconds.These slice dynamic images were processed with the CT perfusion software package.Cerebral blood flow,cerebral blood volume,and mean transit time were measured within the specific regions of interest of the brain,and quantitative analysis was performed.

在常规轴面CT扫描后选取基底节及其相邻层面，经肘静脉团注对比剂，同时开始连续50 s的四层动态扫描，重建的198幅动态图像使用CT脑灌注软件包进行处理，获得灌注图像，测量所选脑内感兴趣区的血流量、血容量及平均通过时间，并对其进行定量分析。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
