Abstract］ objective to identify the relationship between serum homocysteine and carotid artery atherosclerosis in patients with cerebral infarction and effects of foliate,methylcobalamin.methods the concentrations of hcy were determined by means of fluorescence polarization immunoassay and carotid arteries was examined with color doppler ultrasound in 165 patients with cerebral infarction.the subjects were divided into 4 groups according to the severity of lesion of carotid artery.the concentrations of hcy were compared in different groups.the patients with hyperhomocysteinemia received foliate and methylcobalamin.results when lesion of carotid artery became severer,serum hcy was higher.the intima medial thicknesses of carotid artery were significantly decreased in patients with hyperhomocysteinemia who received foliate and methylcobalamin for two years.conclusion hyperhomocysteinemia may play an important role in development of carotid artery atherosclerosis.the intervention of foliate and methylcobalamin may reduce carotid artery atherosclerosis.

摘要］ 目的探讨脑梗死患者颈动脉病变与血清同型半胱氨酸水平的关系及叶酸、甲钴胺长期干预对其影响。方法对165例急性脑梗死患者进行血清hcy的测定及颈动脉超声检查，并按动脉硬化的程度分组，比较不同程度颈动脉粥样硬化患者hcy水平，部分高hcy血症患者给予叶酸、甲钴胺干预，随访2年。结果随着颈动脉病变程度的加重，血清hcy浓度呈上升趋势，高hcy血症干预者动脉内中膜厚度明显减小。结论高hcy血症对颈动脉粥样硬化的形成起重要作用，长期给予叶酸、甲钴胺干预可能减轻颈动脉粥样硬化。

RESULTS: The imaging features of CBT were masses located at the bifurcation of the carotid artery, with abundant blood supply in the tumor, the internal and external carotid arteries shifted, the bifurcation of the carotid artery increased like goldcup in DSA. The imaging features of the neurilemmoma were masses located behind the bifurcation of the carotid artery, and the carotid bifurcation was normal, no blood supply in the tumor, but carotid arteries shifted.

结果：颈动脉体瘤的CDFI和DSA特征为：颈总动脉分权处单发性肿块，并与其紧密相连，瘤体内血流极为丰富，瘤体使颈外动脉向前内移位、颈内动脉向后外移位，颈内、外动脉分权角度增大明显，DSA呈高脚杯状改变；神经鞘瘤紧邻颈动脉，颈总动脉分权处角度无改变，瘤体内血流信号不丰富，瘤体使颈动脉向前、外移位。

PART ONEInvestigation on Hp CagA+ strain infection condition and pathogenesis risk analyze in patients of carotid atherosclerosisObjective To observate pathological changes of carotid atherosclerosis as well as Hp infection situation, examinate blood fats, blood serum hs-CRP, blood plasma YKL-40, blood serum sCD14, analyze relations between Hp or Hp CagA+ strain and carotid atherosclerosis, and explore possible mechanism of carotid atherosclerosis caused by infection.

然后进行基础动物实验，应用Hp CagA+菌株干预高脂血症大兔，建立Hp CagA+菌株感染致兔颈动脉粥样硬化模型，进行血清Hp抗体、hs-CRP、血浆YKL-40水平检测、斑块内Hp DNA，进一步求证Hp CagA+菌株感染和颈动脉粥样硬化形成的相关性，Hp CagA+菌株感染是否可促进颈动脉粥样硬化的形成，深入探讨其可能机制，以期为颈动脉粥样硬化形成的病因学研究提供实验基础，为临床治疗颈动脉粥样硬化提供新的策略，从而完善其防治模式。

1.Preliminary studys on the carotid artery parameters Detected by Intracavitary Convex Array ProbePurpose and SignificanceFinal results of The North American Symptomatic Carotid Endarterectomy Trial and the MRC European Carotid Surgery Trial displayed that carotid artery must be observed intimately when stegnosis degree is higher than 50%and it must have an operation or interventional therapy in time when stegnosis degree is higher than 70%.

1、腔内凸阵超声探头检测颈动脉参数的初步研究目的和意义北美有症状颈动脉内膜剥脱试验(The North American Symptomatic CarotidEndarterectomy Trial NASCET)和欧洲颈动脉手术试验(European Carotid SurgeryTrial，ECST)研究结果显示，当颈动脉狭窄程度超过50%时要密切观察病情变化，当狭窄程度超过70%时要及时手术或介入治疗，治疗后可大幅降低脑梗死的发生率。

Results There are 17 cases whose CTA display rate is 100% of common carotid artery, external carotid artery and internal carotid artery. 18 branches internal carotid artery stenosis, in them 10 branches light stenosis, 4 branches midrange stenosis, 3 branches heavy stenosis, 1 branches obstruction.

回顾性分析17例经临床或DSA检查证实的颈动脉狭窄的CTA检查结果，对血管显示情况进行评价，其中7例进行了DSA检查并与CTA结果比较。

Methods Using Seldinger technique method,guide Magic-BD micro-catheter with Balt detachedable rubber ball to the fistulas level,when verified the ball inside the fistula of carotid-cavernous sinus but outside the carotid artery,filled the ball fully enough with iodine material until the abnormal noise disappear and release the ball remained the internal carotid artery patent.

采用Seldinger法插入导管鞘后，用带Balt可脱球囊的magic-BD导管透视下经导引管送达瘘口水平，当球囊突然"低头"或改变方向时，表示球囊已通过瘘口，进入海绵窦。以等渗造影剂交换气体后充盈球囊至杂音消失，造影证实瘘闭塞完全，并保持颈动脉通畅。

If you directly measure central blood pressure, that is to say carotid blood pressure, for instance carotid systolic blood pressure, with penetration to the other side of carotid artery, then you are in the buzzy thing to determine exactly the ventricular load, the load on the brain, because it is very similar to the load in the kidney-the hemodynamic input into the kidney.

如果你直接测量中心血压也就是颈动脉压的话，比如测量颈动脉收缩压，这个时候你才能准确地告诉我心室的负荷是多少，大脑的负荷是多少，因为颈动脉的血流负荷与肾脏的血流负荷--即进入肾脏的血液很接近。

Surface tear of the endomembrane and atherosclerotic plaque induced by balloon dilatation, mechanical expansion and carotid sinus draw-off can adjust compliance of the carotid wall, change sensitiveness of carotid artery receptor, cause instability of hemadynamics and defluxion of plaque fragments, lead to hypotension, bradycardia, hypertension and vascular embolism. How to control and reduce occurrence of above-mentioned complications is a main problem in present studies.

但由于球囊扩张、支架置入机械扩张和牵拉，颈动脉窦引起内膜和动脉粥样硬化斑块的表面撕裂，调整了颈动脉壁顺应性，改变了颈动脉受体的敏感性，引起血液动力学不稳定和斑块碎片脱落，引起低血压、心动过缓、高血压及血管栓塞等并发症，如何控制和减少上述并发症的发生是目前研究的主要问题。
