Methods： A total of 100 male Wistar rats were randomly divided into the control group and the qi-deficiency syndrome model group, 50 rats in each group. The qi-deficiency syndrome model was established by feeding the animals with hyper-alimentation diet in combination with restricting movement for 10 weeks. Changes of common chemical signal molecules related to NEI and vascular endothelial functions were measured by the end of the experiment. Furthermore, their internal relevance was analyzed by the method of canonical correlation analysis. Results： The vascular endothelial structure and function were obviously injured in the model group. Compared with the control group, the chemical signal molecules, such as 5-hydroxytryptamine （5-HT）, corticosterone （CORT）, triiodothyronine （T3）, tetraiodothyronine （T4）, angiotensin Ⅱ （Ang Ⅱ）, interleukin-1 （IL-1）, and tumor necrosis factor-α （TNF-α） in peripheral blood of the model group （n=43） were changed significantly （P〈0.05 or P〈0.01）. Canonical correlation analysis showed that vascular endothelial dysfunction was correlated to the changes of these signal molecules in the NEI network. Conclusions： Comfortbased lifestyle induced not only vascular endothelial dysfunction but also an imbalance of the NEI network. Vascular endothelial dysfunction and the imbalanced NEI network interacted with each other, and an imbalance of the NEI network may be the pathophysiologic basis for the genesis and development of vascular endothelial dysfunction, even diseases of the blood vessel.展开更多
