Result: The normal inner/ outer spiral vessels of basilar membrane, strial blood vessels had no permeability, whereas the capillaries of endolymphatic sac showed a certain permeability.

结果：正常对照组基底膜内、外螺旋血管、血管纹毛细血管不具有通透性，正常内淋巴囊毛细血管具有一定通透性。

According to recent advances in the biomedicine of vessels, we have postulated that the tissue renin-angiotensin system ( RAS) of the vessels may play an important role in the occurrence of the differentiated vascular adaptation during microgravity.

此外，根据现代血管生物学研究进展，我们认为血管组织局部的肾素-血管紧张素系统（局部RAS）可能在调控动脉血管分化性适应变化中发挥重要作用。

Under the satisfied CPA condition, patients were told to hold breath. 3D key was started. The tumor vascularity was reconstructed with 3D-CPA and the images were stored in MO to further study the whole distribution of tumor vessels.

在CPA图像清晰状态下，嘱患者屏气，启动3D键对肿瘤血管进行三维重建，图像存储于MO以进一步观察肿瘤血管整体分布，计测3D-CPA肿瘤血管指数VI，即单位体积内的血管条数。
