Norepinephrine ameliorates sepsis-associated acute kidney injury through inhibiting damage of renal tubular epithelium induced by macrophage inflammatory response.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundNorepinephrine (NE) has been reported to not only regulate cardiovascular activity but also influence inflammatory responses. But its role in sepsis-associated acute kidney injury (SA-AKI) has yet to be elucidated.
methodsSA-AKI mouse model was induced by intraperitoneally instillation of lipopolysaccharide. After treatment with NE, haemodynamic changes, kidney pathological injury, kidney funcion, systemic and kidney inflammatory responses, were evaluated. Cytokine levels and nuclear factor κB (NF-κB), MAPKs and Akt signalling pathways of macrophages were measured in vitro. Intercellular tight junction and cell viability were detected to evaluate the effect of macrophage inflammatory response on renal tubular epithelium.
resultsNE enhanced cardiovascular haemodynamics, alleviated kidney histopathological injury and inflammatory cell infiltration, lowered the levels of kidney cytokines, NGAL, and KIM-1, as well as serum cytokines in SA-AKI mice. In vitro experiments indicated that NE suppressed the secretion of TNF-α, IL-6, and enhanced IL-10 secretion via a mechanism that involves inhibiting NF-κB rather than MAPKs or Akt activation of macrophage, and further alleviated the damage of renal tubule epithelium.
conclusionNE ameliorated SA-AKI via a mechanism that involves inhibiting NF-κB activation to suppress excessive inflammatory responses of macrophages, and improve the injury of renal tubule epithelium, on its basis of improvement of hemodynamic changes in septic mice.
