The suboccipital sinus , in the suboccipital region , is similar to the cavernous sinus in embryological development and functional and pathological features , as well as transitional patterns of the arterial wall structures 摘要枕下海绵窦位于枕下区，与海绵窦在胚胎学发育、功能和病理学特征以及动脉壁的过渡类型上都具有相似性。
Strenuous activity was identified as a precipitating factor for aortic dissection in 24 of the 90 patients ( 27 % ) contacted . severe emotional stress was identified as an inciting event in 36 cases ( 40 % ) 电话随访的90名患者中的24名( 27 % )认定重体力作业为主动脉壁夹层形成的促发因素。 36例( 40 % )患者将严重的情绪应激认定为激发事件。
At higher magnification , vasculitis with arterial wall necrosis is seen . note the fragmented remains of neutrophilic nuclei ( karyorrhexis ) . acute inflammation is a non - selective process that can lead to tissue destruction 高倍镜下，脉管炎患者动脉壁坏死，可见嗜中性粒细胞核碎片(核碎裂) 。急性炎症是一种非选择性的病理过程，可导致组织的损伤。
Such aneurysms are " congenital " in the sense that the defect in the arterial wall is present from birth , but the actual aneurysm takes years to develop , so that rupture is most likely to occur in young to middle age adults 就出生时动脉壁缺陷这一点来看，多发性颅底小动脉瘤是先天性的，但实际上动脉瘤需要数年时间才能形成，因此颅底小动脉瘤破裂最可能在青年到中年发病。
In this paper , we reviewed the history of the studies about the mechanical properties on arterial walls , and introduced the experimental studies about the arterial walls , which included the structure of the arterial wall , experimental model , theoretical models of thin and thick wall cylinders , method of stress and strain analysis and the difference between dynamic and static experiments , and discussed the fields of tissue engineering , remodeling of the artery and the relation between stress and growth 本文首先对动脉壁力学性质研究的历史做了回顾，其中着重介绍了动脉壁力学性质的实验研究。包括动脉壁的结构、实验模型的研究、薄壁筒和厚壁筒理论模型的研究、应力和应变分析方法以及动态和静态实验的区别，并对当前研究的热点问题，如组织工程、动脉重建和应力与生长的关系作了探讨。
Beside routine clinical work , the new machine will be used for the latest research projects undertaken by the division of cardiology . these involve the assessment of cardiac function in patients with a variety of cardiac disorders , the detection of abnormal motion due to shortage of oxygen supply to the heart muscle using a sophisticated colour doppler based technique , and also research into arterial diseases and the effect of various treatments 这部仪器可广泛应用于需求量激增的常规临床检查，包括测量颈动脉及其它动脉壁的厚度，有效诊断动脉血管病，亦可用于心脏科研究工作计划，如测量不同类的心脏病患者的各种心脏功能、诊断因心肌缺氧供应而引致的不正常心肌活动，同时又可研究动脉血管病及各种治疗的效果。
Renin secretion is controlled by at least four mechanisms that are not mutually exclusive : a renal vascular receptor responds to changes in tension in the afferent arteriolar wall ; a macula densa receptor detects changes in the delivery rate or concentration of nacl in the distal tubule ; circulating angiotensin has a negative feedback effect on renin secretion ; and the sympathetic nervous system stimulates renin secretion via the renal nerve mediated by receptors 肾素的分泌至少受四种互不排斥的机制控制：肾血管受体对向心小动脉壁张力变化的反应；致密斑受体发现远端肾小管内氯化钠传递速率或浓度的变化；循环的血管紧张素对肾素的分泌的负反馈效应；和交感神经系统经由受体介导的肾神经刺激分泌肾素。
The diabetes coronary heart disease high reason of incidence of a disease is many - sided , yet chiefly is the fat supersession chaos , and creates glycerine three grease and the cholesterol to get higher , that sweet and protein are metabolized oddly be able to create myocardium capillary pathological changes and the myocardium supersession chaos , but the flora nervous system chaos easily arouses that blood vessel pulling force adds and injures the artery breastwork 糖尿病冠心病发病率高的原因是多方面的，但主要是脂肪代谢紊乱，造成甘油三脂和胆固醇增高，糖和蛋白质代谢的失常会造成心肌的微血管病变和心肌代谢紊乱,而植物神经系统紊乱易引起血管张力增加而损伤动脉壁。
Also , the researchers discoered that the initiating mechanism is a lack of the key signaling molecule nitric oxide in the artery wall , which has multiple beneficial roles in the cardioascular system , as well as made a connection between nitric oxide and the proteins responsible for angiotensin ii actiity 还有，研究者们还发现最初的机制可能是在动脉壁上缺少一种关键的氧化亚氮信号分子，它在心血管系统中有许多益处，它还联系氧化亚氮和负责血管紧张素活性的蛋白。
