摘要
从过去一个世纪以来，果糖的进食量急剧增加，并且与糖尿病、肥胖、肾衰、高血压等的发生密切相关。目前越来越多的证据证明过量的果糖饮食会引起盐敏感性高血压，其发生机制十分复杂，但是肾脏可能在其中扮演着重要的角色。本文主要阐述了果糖诱导盐敏感性高血压的肾相关机制，包括肾素原受体依赖的肾内肾素-血管紧张素系统的活化，肾内Na+转运体钠氢交换子3 (sodium/hydrogen exchanger 3, NHE3)和Na-K-2Cl共转运体(Na/K/2Cl cotransporter, NKCC2)的活化，肾内尿酸产生的增加，肾内一氧化氮合成的降低，以及肾内活性氧产生的增加，并以此为理论依据提出潜在的治疗盐敏感性高血压的靶点或策略。

Abstract
Fructose intake has increased dramatically over the past century and the upward trend has continued until recently. Increasing evidence suggests that the excessive intake of fructose induces salt-sensitive hypertension. While the underlying mechanism is complex, the kidney likely plays a major role. This review will highlight recent advances in the renal mechanisms of fructose-induced salt-sensitive hypertension, including (pro)renin receptor-dependent activation of intrarenal renin-angiotensin system, increased nephron Na+ transport activity via sodium/hydrogen exchanger 3 and Na/K/2Cl cotransporter, increased renal uric acid production, decreased renal nitric oxide production, and increased renal reactive oxygen species production, and suggest actions based on these mechanisms that have therapeutic implications.
Key words: fructose; salt-sensitive hypertension; intrarenal renin-angiotensin system; (pro)renin receptor; nephron ion transporter; uric acid; nitric oxide; reactive oxygen species;
