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。

METHODS: Rabbit models of autogenous vein graft were generated in both groups. After anaesthesia, a median incision was made at the neck to dissociate external jugular vein and common carotid artery of the left side. Following blood flow was blocked at the upper and down sides of the common carotid artery, blood vessels were transected to collect 4.0-5.0 cm external jugular vein at the left side, and placed among the common carotid artery at the same side after inversion. End-to-end anastomosis was performed using discontinuous ecstrophy.

Methods:Wistar rats were divided randomly into sham-operation group(n＝6) and ischemia- referfusion group (n＝12).Common carotid artery and external carotid artery were ligated,internal carotid artery and pterygopalatine artery were undivided.Pricking with eye scissors at the distal end of CCA for intralumin suture.By adjusting the suture arc direction to avoid entering the pterygopalatine artery,then withdraw the suture for referfusion 1 h later.

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%.
