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。

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。

Long Hosel These designs are usually elongated plumber-necks and are used to create face-balancing. Although they look very similar to the standard plumber-neck design, the extra length definitely creates a different feel, which you should take into consideration before selecting a putter with this type of hosel structure. Be aware that the elongated plumber-neck design doesn't always result in face-balancing; many, in fact, are toe-balanced.

Long Hosel：外观看来，这跟第一种杆颈是一样的，但是他的杆颈柄较长，这是为了增加杆面平衡所做的设计，较长的杆颈提供了不一样的手感，不过在选择这种推杆之前，还是要建议多尝试看看，这样的长颈也就增加了杆头根部的重量，所以平衡了第一款中提到的杆趾部加重，也就是小弟二部曲中提到的"平衡式"推杆。

Result: Among 40 cases of hyperpiesia, there are 32 cases with arteria carotis atherogenesis in different extent, and its incidence is 80%; Among 32 cases of cerebral vessels diseases: Twenty-one cases had arteria carotis atherogenesis, and its incidencewas 66%. Among 18 cases of diabetes complicated with hyperpiesia, 13 cases had arteria carotis atherogenesis, and its incidence was 72%; Among 6 cases of diabetes, 2 cases had arteria carotis atherogenesis, and its incidence was 33%.

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.

两组兔均建立自体静脉移植模型，麻醉后颈前正中切口，游离出左侧颈外静脉及颈总动脉，在颈总动脉的上下两端阻断血流后，横断血管，取左侧的颈外静脉4.0~5.0cm，上下倒向后置于同侧颈总动脉之间，采用间断外翻法行端端吻合。
