血管狭窄

By the examination of MRI, histopathology, and the caculation of survival rate and percentage of patency, the viability of graft status of autograft tracheas wrapped in one-side sternomastiod muscule flap and two-side sternohyoid muscle flap based on different pedicle, effects of neck muscle associated with bFGF on length of autografts, and limit of warm ischemia time on tracheal allograft before cryopreservation were evaluated in rabbits.

肿瘤、先天性疾病、炎症或其他原因引起的气管狭窄，切除病变气管行气管端端吻合术是最理想的方法。而长段气管切除术后，则需要行气管重建。20世纪以来随着免疫学的发展，肾脏、心脏等脏器移植已在临床应用成为可能，人们注意到气管移植的重要性。因此，气管移植成为长段气管缺损重建的方向，其面临的主要问题是移植气管的再血管化、免疫抑制、供体的来源与保存等。

The authors note that the increase in the diameter stenosis in patients on antiplatelet therapy was unexpected, and could be "related to asodilatation caused by dipyridamole or neurohumoral effects on coronary arteries after MI."

作者指出，抗血小板治疗患者直径狭窄增加是意料之外的，可能&与潘生丁引起的血管扩张或心肌梗死后神经体液因素对冠状动脉的影响有关。&

Exercise testing may explore myocardial blood perfusion,nuclein myocardial imaging may accurately explore range and extent of myocardial ischemia and predicate coronary restenosis for patients with coronary stenting.

对于冠状动脉内支架植入术后病人进行运动负荷试验可了解患者的心肌血流灌注状况，核素心肌显像能准确提供心肌缺血的范围和程度，可预测血管的再狭窄。

Methods: Twenty coronary arteries from eight perfusion-fixed autopsy heart were dissected, straightened and scanned by UFCT. Then each coronary artery was divieded into ocrresponding segments, representative histological 3 mm sections were stained with Orcein. Atherosclerotic area(mm2) and luminal narrow per segment were quantified on Leica Imaging System.

从8例压力灌注固定后的心脏标本中分离出20支冠状动脉，拉直后，超高速CT扫描；每支冠状动脉分成相应的3mm血管段，组织切片，地衣红染色，Leica图像分析仪上计算冠状动脉管腔面积狭窄率。

In the procedure, two cases with branches ostial lesion appeared dissection and stent was implanted, the remained stenosis ratio was 10%～50%. The SafeCut balloon success rate was 100%, and no hospitalized complications such as acute myocardial infarction occurred.

对分支血管行SafeCut球囊扩张后有2例因内膜严重撕裂而置入支架，其余病变残余狭窄为10%～50%，成功率达100%，无急性心肌梗死等严重并发症。

Like MRA, CTA is useful when carotid duplex is ambiguous, permitting isualization of aortic arch or high bifurcation pathology, reliable differentiation of total and subtotal occlusion, assessment of ostial and tandem

CTA能够使主动脉弓和高位颈动脉分叉显影，可靠区分全部和部分血管闭塞，评估开口和串联性狭窄，而且能够对心律不齐，瓣膜性心脏病，心肌病患者的颈动脉疾病进行评价。

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。

The results are: 1 the stricture of the capillaries of stria vascularis was observed in most cochleae of rickety rats and, segmental deletions of the outer hair cells on the first turn of cochlea were found in a small number of rickety rats; 2 the perilymphatic ionized calcium concentration significantly re- duced and the threshold of CAP (Compound Action Poten- tials of the eighth nerve) significantly rose in rickety rats in comparison with those of normal control; 3 gentamicin results in an increase of the perilymphatic ionized calcium concentra- tion in rickety rats; 4 the cochleae of the rickety rats appeared to be less vulnerable to the ototoxicity of gentamicin than the normal one.

研究包括两个方面，其一是&佝偻病的感觉神经性耳聋及其对庆大霉素耳毒性作用的耐受性&，系用大白鼠建立维生素D缺乏性佝偻病动物模型，发现：（1）佝偻病大白鼠耳蜗血管纹毛细血管狭窄，少数动物耳蜗底回外毛细胞有节段性缺失；（2）佝偻病大白鼠的耳蜗鼓阶外淋巴钙离子浓度降低，CAP（听神经复合动作电位，以下简称CAP）听阈提高；（3）庆大霉素可使佝偻病大白鼠耳蜗外淋巴钙离子浓度上升；（4）佝偻病大白鼠耳蜗在功能和形态上都比正常者更能耐受庆大霉素的耳毒性损害。

The loss of normal lung parenchyma leads to pulmonary hypertension that leads to thickening of the small arteries along with reduplication to form a plexiform lesion, as seen here in a peripheral pulmonary artery.

正常肺实质的损伤可导致肺血管的压力增高，在此切片肺动脉的周边部可见肺内小动脉的管壁增厚，管腔狭窄引起肺动脉血压增高。

Comparison of preoperator of carotid endarterectomy and Percutaneous transluminal stenting with postoperator in measuring the vascular diameter and area of cross section using CTA . Statistical significance was determined using t test. Results: Using a 70% cutoff value for stenosis, CTA and DSA were in agreement in 35 of 37 vessels(95%).

用X2检验评价CTA与DSA检测血管内软斑块的差异有否显著意义；用配对t检验评价内膜切除术和支架置入术前、术后ICA狭窄处直径及横切面面积的差异有否显著意义。
