The staging is based on the extent of nodal and extranodal involvement.

分期基于淋巴结和结外受累程度。

Usually, lymphomas develop in lymph nodes and they're called nodal lymphomas.

通常，淋巴瘤发生在淋巴结，因而被称为淋巴结淋巴瘤。

He was their nodal point, their focus, their expression in a single term.

他他们， 他们焦， 他们在一个任期内表现。

There's also nodal marginal zone lymphoma, which happens within lymph nodes, and splenic marginal zone lymphoma which happens in the spleen.

还有淋巴结边缘区淋巴瘤，发生在淋巴结内；以及脾边缘区淋巴瘤，发生在脾内。

Heart blocks are classified by location where the blockage occurs: - SA nodal block, or SA block – blockage within the SA node.

-窦房结结阻滞，或窦房阻滞--窦房结内阻滞。

So understanding one disorder has unlocked a nodal biological mechanismand insights for the treatment of many more diseasesaffecting surprisingly distant parts of the body, like the brain and the kidney.

因此，了解一种疾病已经解开了生物学机制，并为治疗影响身体遥远部位（例如大脑和肾脏）更多疾病提供了见解。
