1 · What the graph read from it

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.

2 · The registry

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

objectivesThe aim of this study was to explore mechanisms by which salvianolic acid A (SAA) revealed its anti-inflammatory activity, in lipopolysaccharide (LPS)-stimulated RAW264.7 cells. MATERIALS AND

methodsNitric oxide (NO) concentration was determined by the Griess reaction and cell viability was assessed by MTT assay. Interleukin-6, TNFα and interleukin-1β were determined by ELISA. The RAW264.7 cells were transfected with siRNA against p38 or HO-1. Expressions of COX-2, inducible NO synthase (iNOS), NF-κB, HO-1, p-p38 and phosphorylation of IκB kinase α/β were detected by western blotting. Potential targets of SAA were analysed by homology modelling, target prediction, protein-protein interaction prediction and docking studies.

resultsSalvianolic acid A suppressed LPS-triggered production of NO, TNFα and Interleukin-6. It also reduced protein expression of inducible NO synthase and COX-2, and reduced translocation of NF-κB to nuclei. Moreover, SAA promoted expression of phosphorylated p38, and downstream HO-1. Zn (II) protoporphyrin IX, a specific inhibitor of HO-1, or siRNA against HO-1 could effectively increase transfer of NF-κB. SAA was predicted to target amyloid-beta protein-like protein and arachidonate 5-lipoxygenase, that could regulate p38 and HO-1.

conclusionsIn silico analysis and experimental validation together demonstrated that SAA exhibited its anti-inflammatory effect via the p38-HO-1 pathway in LPS-stimulated RAW264.7 cells, reduced transfer of NF-κB to the nuclei and thus reduced production of inflammatory mediators.
