学员疑问：这句话括号里面怎么分析结构？
老师解答：This is congruent with evidence主句
(that intrathecal administration of TGF-R1 inhibits development of neuropathic allodynia to a similar extent as miR-21 (silencing in sensory neurons现在分词短语作后置定语，修饰miR-21),
and intrathecal injection of bone marrow stromal cells,(which release TGF-β1
定语从句，修饰cells), reduces neuropathic hypersensitivity to a similar (extent) to BMDMs (transfected with antagomir-21后置定语，修饰BMDMs)).同位语从句，解释说明evidence
点评分析：这句话的主句很容易理解。关键是括号内的同位语从句，是由and连接的并列句；and前一句话的主干是intrathecal administration of TGF-R1 inhibits development；of neuropathic allodynia 是介词短语作后置定语，修饰development；to a similar extent 是介词短语作程度状语；as miR-21是介词短语作方式状语；and后一句话的主干是intrathecal injection reduces neuropathic hypersensitivity。
