After controlling for age and gender , the team found associations between a smaller ratio of retinal arterioles and venules with mri findings , including prevalent infarcts , worsening white matter grade , and incident infarct 在对年龄和性别进行控制后，研究小组在磁共振结果中发现较小比率视网膜小动脉和小静脉之间的联系，包括普遍的梗塞，恶化的白质程度，以及偶发的梗塞。
Sticking sluggish blood disease high is the pathology that is main show with haemal viscosity heighten is asked for integratedly , blood stream obstruction is increased , flow is decelerated , affect to small artery and blood capillary and small loop especially apparent , cause quantity of constituent blood perfusion to decrease , generation is short of blood anoxic symptom 高粘滞血症是以血液粘度增高为主要表现的病理综合征，血流阻力加大，流动减慢，尤其对小动脉和毛细血管及微循环影响明显，致使组织血液灌注量减少，产生缺血缺氧的症状。
Exercise could lead to remodeling of icn , of which normal exercise load might lead to proportional increase of cardiac and icn , adapting oneself ot transmit of contractility between myocardial bundles and cardiac muscle cell ( cmc ) under conditions of myocardial hypertrophy ; and exercise overload might lead to increase of a large number of different collagen among myocardial bundles , cmc , arteriole and capillary , that could lead to increase of stiffness and descent of systolic and diastolic function of heart 运动可引起心肌间质胶原网络结构的重塑，一般运动负荷可使心肌与间质胶原网络同步增长，以适应心肌细胞肥大收缩力增加从而保证肌束间及心肌细胞间力的传递；运动超负荷可使心肌束间、心肌细胞间以及小动脉和毛细血管间不同类型胶原大量蓄积增生，导致心脏的僵硬度增加，舒缩功能降低。
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 results show that : the glomerulus of the mouse consists of a lobular arteriole within the glomerulus , capillary meshwork lobules and communication branches between the lobules and the efferent arteriolar roots ; there are some sublobular microcirulatary units in lobules ; the glomerulus of chrysolophus pictus is only a tortuous vascular ball ; there are no branches anastomosed between the vascular ; the afferent arteriole is a branch , efferent arteriole is one either , but some efferent arteriole has branches 结果表明：小白鼠肾小球由小球内小叶微动脉、毛细血管网小叶及小叶间交通支和小叶输出血管构成，小叶可分出亚单位；红腹锦鸡肾小球为一簇迂回盘曲的血管团，血管间未见有复杂的分支和吻合；小白鼠和红腹锦鸡入球小动脉和出球小动脉均为一支，但有的出球小动脉有分支。
