The kidney also secretes the hormone erythropoietin which stimulates the production of red blood cells from the bone marrow.

肾也分泌促红成素，后者能刺激骨髓红。

Treatment involves correcting the underlying condition, or, in severe cases, RBC transfusions or erythropoietin injections.

治疗方法包括治疗原发疾病，或在严重的情况下，采用红输注或红成素注射。

Meanwhile, the kidneys make more erythropoietin, a hormone that increases red blood cell production.

同时，肾脏更多的促红成素，这是一种增加红成的激素。

In chronic kidney disease, erythropoietin levels fall and this leads to lowered production of red blood cells, and ultimately anemia.

慢性肾病中，促红成素水平降低，这导致红减少，最终导致贫血。

The kidneys regulate our levels of red blood cells through the release of erythropoietin, a hormone which causes marrow to increase production.

肾脏通过释放促红成素来调节我们的红水平，促红成素是一种导致骨髓增加量的激素。

Steroids, erythropoietin (EPO) and newer, less familiar performance-enhancing drugs (PEDS) will have bulked their muscles, enriched their blood and allowed them to train harder than unenhanced humans would find possible.

类固醇、促红成素(EPO)和更新的、不太为人所知的提高体能的药物(PEDDS)能够让服用者的肌肉更加强健，血液更加丰富，如此他们就能够比普通人类更加努力地训练。

And this is usually done with either blood transfusions, using your own blood, or by injecting yourself with erythropoietin, a molecule that stimulates the production of more red blood cells.

这通常通过输血、使用自己的血液或给自己注射促红成素来完成，促红成素是一种刺激更多红的分子。
