本文以心算实验对高、低神经质维度的人群组构成心理应激刺激，结果发现高神经质维度组在心理应激刺激后甲襞微循环（简称ＮＦＭＣ）血管管径收缩幅度和持续时间均大于和长于低神经质维度组，ＮＦＭＣ血液流速变慢时间前者明显短于后者，提示心理应激、人格神经质维度和微循环（简称ＭＣ）三者间存在着明显的关系。 

The changes of nailfold microcirculation were observed in 60 healthy adults before and after they conducted a task of mental arithmetic under time pressure. The subjects were divided into two groups of
high N score or low N score according to neuroticism subscale of EPQ. The results revealed differences of changes in nailfold microcirculation between these two groups. Compared to subjects with low-N score . the high 一N score group showed much larger degree of narrowed capillary diameter and longer time of continued capillary ontracion. while shorter time of showing slowed RBC velocity.  The possible relations among microcirculation，stress response and neuroticism were discussed.
