Then it is used to create a focal lesion on the epicardium or endocardium by delivering temperatures as low as -80oC at its tip.

Results The number of cases with hemoptysis caused by tracheobronchitis, idiopathic pulmonary hemosiderosis, pulmonary tuberculosis, cardiovascular and pulmonary vascular malformation, and bronchiectasis were 18 (43%), 7(17%), 4(10%), 3(7%), 3(7%), respevtively. Duplication of digestive tract and tumor might cause the symptom of hemoptysis in childhood.

结果 42例咯血患儿中，气管、支气管炎引起的咯血18例(43%)，特发性肺含铁血黄素沉着症7例(17%)，支气管内膜、肺结核4例(10%)，心、肺血管畸形及支气管扩张症分别为3例(各占7%)，消化道重复畸形、肿瘤所致的咯血在儿童也可见到。

The degradating and redistributing of ECM were migration of VSMC and vascular remodeling through inhibiting the production of PDGF-BB and the activation of MMPs so to prevent the vascular stenosis.⑤Orthotopic hybridism in situ: The expression of MMP-3 increased after operation, the tendency and intensity were parallel to the expression of NF-κB. Tongxinluo could decrease the expression of MMP-3 and NF-κB. The study showed that the producting and activating of MMP-3 were modulated by NF-κB. The inhibition to the producting and activating of MMp-3 of Tongxinluo was mediated by inhibiting the activating of NF-κB. Conclusion ①The rabbit vascular stenosis model could be established successfully by plain balloon damage, the operation process was easy, economical and practical.

①单纯球囊损伤可成功建立典型家兔血管狭窄模型，操作方法简单，经济实用；②以VSMC增殖、迁移为主的内膜增厚以及以ECM降解、合成与再分布所致的血管重构是导致受损血管狭窄的根本原因；③通心络能明显抑制VSMC的增殖、迁移和ECM降解、合成，阻止血管内膜增生和血管重构，防止受损血管狭窄；该作用可能与其减少和阻止PDGF-BB的产生和活性，以及抑制MMPs的表达和恢复MMPs/TIMPs平衡有关；④通心络能显著抑制球囊损伤后血管内膜增生和血管重构，可能与其保护血管内皮，改善内皮功能，增加血清NO含量有关；⑤通心络抑制内膜增生和血管重构，减轻受损血管狭窄，还可能是通过抑制NF-κB的活化途径而起作用的。

We selected 33 segments which show hypokinetic or akinetic at resting echocardiography to undergo identification ofviability.Pulsed-wave Doppler tissue imaging was recorded at mid-point of endocardium of every selected segment, at inner and outer mitral annul us as well.Then we measured the parameters.

应用16节段半定量法分析室壁运动，选取静息状态下低动力或无动力的心肌节段进行存活性的评价，留取受检节段长轴方向心内膜中点及二尖瓣内、外环脉冲组织多普勒频谱图，测量各参数。

Result The improved mathematical model was applied to sequential echocardiographic images and the experimental results showed that endocardial boundary can be accurately detected.

结果将改进的快速行进模型应用于心超图像中心脏内膜边缘检测，实验结果表明该方法能够准确地检测、跟踪出心脏内膜边缘。

Objective To study a new computerized automatic method for endocardial boundary estimation and tracking in sequential echocardiographic images.

严加勇 ，庄天戈目的探讨一种对心超图中心脏内膜边缘进行检测的自动化方法。

Based on Jilin local pig streptothrix popular strains, we have chosen the representative F6 strain to be proceeded completely characteristic authenticates, which can provide consult data for research of manufacture of polyvalent inactivated vaccine.At present, there are reports of pig streptothrix in America, England, France, Russia, Japan, India, Denmark, Canada etc.

目前，美国、英国、法国、俄罗斯、日本、印度、丹麦、荷兰、加拿大等国均有关于猪链球菌分离鉴定及血清型分型的报道，从患败血症和脑炎的猪体内分离的链球菌主要是R群的猪链球菌H型，和S群的猪链球菌I型，只有少数C群、D群和L群引起心内膜炎和败血症的病原菌。

After administration of L-N〓-nitro-Arginine, a specific antagonist of NOS, it was found that the basal and stimulated NO release of blood vessels (aorta, internal carotid, renal and mensenteric artery) was decreased further. The increase of coronary blood flow stimulated by Ach was also reduced further, while the platelet aggregation degree and erythrocyte aggregation index increased significantly. Pathological examination indicated that aortic endothelium was destroyed, the blood vessels in cerebral, cardiac and renal tissues were hypertrophied further and some were almost occluded. The above fin dings resulted in SHR feeded with L-NNA having high incidence of stroke rate and high degree of renal cirrhosis when compared to control SHR. The infarct and hemorrhagic focuci in cerebral tissues, infarct focuci in cardiac tissues, atrophy and hyalinedegeneration of renal glomeruli and degeneration even necrosis of renal tubuli in renal tissues were al so found. The increase ratio of brain and heart to body weight and decrease ratio of kidney to body wei ght further demonstrated that the cerebral, cardiac and renal injuries were aggravated.

在上述结果的基础上进一步给予SHR NOS特异性拮抗剂左旋亚硝基精氨酸后，血管(胸主、颈内、肾及肠系膜动脉)NO基础释放及激动剂刺激释放进一步减少，Ach刺激冠脉流量的增加和胸主动脉内膜NOS活性也进一步减少，血小板聚集程度及红细胞聚集指数显著上升，病理切片显示胸主动脉内皮细胞破坏明显，脑心肾组织内的血管进一步增厚甚至几乎阻塞，导致饲L-NNA的SHR缺血性及出血性脑卒中发生率显著高于对照SHR，脑体重比显著升高；心肌内出现明显的缺血梗塞疤痕灶，心体重比显著升高；肾小球明显萎缩、玻璃样变性，肾小管也变性甚至坏死，使肾硬化程度显著增加呈颗粒性固缩肾，肾体重比也显著减少。

However, persons with congenital heart disease may have a roughened area on the heart lining caused by pressure from an abnormal opening or a leaky valve.

然而，先天性心脏病患者的心内膜上可能有粗糙的区域，是由于受到来自于异常的缺损口或漏的瓣膜的压力引起。

First an advanced snake model based on the gradient vector field was used to segment the contour of the left ventricular and an initial snake line of the contour was got, then optical flow method was used to track the contour of the LV in the successive images. Finally, the Simpson method was applied to calculate the volume of the LV.

首先采用基于梯度向量流的主动轮廓模型对左心室内膜进行分割获取初始轮廓线，再采用光流法跟踪得到心脏序列中后续帧图像的心腔内膜轮廓线，最后采用Simpson方法计算得到左心室容积。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
