Intrarenal dopamine plays a central role on this interactive network. By activating specific receptors, dopamine promotes sodium excretion and stimulates anti-oxidant and anti-inflammatory pathways. Different pathological scenarios where renal sodium excretion is dysregulated, as in nephrotic syndrome, hypertension and renal inflammation, can be associated with impaired action of renal dopamine including alteration in biosynthesis, dopamine receptor expression and signal transduction. Given its properties on the regulation of renal blood flow and sodium excretion, exogenous dopamine has been postulated as a potential therapeutic strategy to prevent renal failure in critically ill patients. The aim of this review is to update and discuss on the most recent findings about renal dopaminergic system and its role in several diseases involving the kidneys and the potential use of dopamine as a nephroprotective agent.展开更多

Nowadays, there are no effective methods to alleviate the process from the initial CRF to ESRD. In clinic, the integrated therapy of traditional Chinese and western medicine is frequently adopted for CRF in combination with hemodialysis, but in the process of treatment, traditional Chinese medicine(TCM) nursing plays a key role. This article mainly explored the key points of common syndromes, TCM nursing methods and health guidance of CRF in order to further develop the advantages of TCM, improve its efficacy and standardized its nursing behavior.展开更多
