求翻译：A紫杉醇和维甲酸联合应用可以一方面抑制血管平滑肌细胞的增生、迁移和分泌，减少新生内膜，另一方面，发挥ATRA对血管内皮细胞的保护作用，促进受损内皮细胞的结构和功能恢复。两者合用理论上可以更大程度的降低再狭窄。是什么意思？

A taxol and Retinoic acid combined inhibition of vascular smooth muscle cell proliferation, migration on the one hand, and secretion, reducing neointimal, on the other hand, play a protective effect of ATRA on vascular endothelial cells, promote the recovery of injured endothelial cell structure and function. Combined the two theoretically possible to a large degree of reduced Restenosis.
