By preventing this initial step of vaso - occlusive disease , improvements in microcirulation were noted 通过对血管阻塞性疾患形成的初步步骤的影响，微循环得到改善。

Transfusions are usually not required nor recommended for standard vaso - occlusive crises or pain associated with sickle cell disease 对于镰状细胞病相关的标准血管阻塞性危象或疼痛，输血治疗常没有必要，且不推荐使用。
3.
Sickle cell disease is any sickle cell disorder in which significant morbidity occurs , such as vaso - occlusive pain crisis ( vpc ) or organ dysfunction 镰状细胞病是一类高死亡率的镰状细胞紊乱，如血管阻塞性疼痛危象（ vpc ）或器官功能紊乱。
4.
Vaso - occlusive pain crises ( vpc ) have been defined as the occurrence of pain in the extremities , back , abdomen , chest , or head that lasts 2 or more hours and cannot be explained except by the presence of sickle cell disease ( 1 ) Vpc是指四肢、背部、腹部、胸部或头部出现疼痛，持续两小时以上，且不能为镰状细胞病以外的疾患所解释[ 1 ] 。
5.
Although regional anesthesia , especially central conduction blockade , produces a favorable sympathectomy and increased limb blood flow , compensatory vasoconstriction in non - anesthetized areas may actually produce vaso - occlusive crises in these areas ( 5 ) 虽然区域麻醉，特别是中枢传导阻滞可产生有效的交感神经阻滞并增加肢体血流，但是非麻醉部位发生代偿性血管收缩，可能使这些部位发生血管阻塞性危象[ 5 ] 。
6.
" the findings are consistent with current recommendations that hormone therapy be used in the short term for relief of moderate or severe vaso - motor symptoms , but not in the longer term for prevention of cardiovascular disease , " the researchers concluded 研究者概括说， “调查结果与当前推荐的激素替代疗法用于短期的治疗缓解中等程度或严重的血管舒缩症状结果相一致，而不是用于长期的心血管疾病的预防。 ”
