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

aimTo investigate the anti-inflammatory effects of asiatic acid (AA) on lipopolysaccharide (LPS)-induced inflammatory response in human corneal epithelial cells (HCECs).

methodsCell viability was measured using a cell counting kit-8 (CCK-8) assay. Quantitative real-time polymerase chain reaction (qRT-PCR) was used to determine the mRNA expression of interleukin-8 (IL-8), interleukin-6 (IL-6), interleukin-1β (IL-1β), tumor necrosis factor-alpha (TNF-α), and transforming growth factor-β (TGF-β) in HCECs. Intracellular reactive oxygen species (ROS) was measured using the ROS assay kit. Glutathione (GSH) concentration was measured using the total GSH assay kit. Akt1 and Akt phosphorylation (p-Akt1) levels were measured by Western blotting and immunofluorescence.

resultsAA induced toxicity at high concentrations and significantly stimulated the proliferation of HCECs at concentrations of 20 µmol/L for 1h. LPS at concentrations of 300 ng/mL for 1h significantly stimulated the mRNA expression of IL-8, IL-6, IL-1β, TNF-α, and TGF-β in HCECs, while the stimulation effects were significantly inhibited by AA (20 µmol/L). In addition, AA was found to decrease the content of ROS, increase GSH generation, and also inhibit LPS-induced p-Akt in HCECs.

conclusionAA decreases the generation of inflammatory factors IL-8, IL-6, IL-1β, TNF-α, and TGF-β in LPS-stimulated HCECs. AA significantly inhibites the intracellular concentrations of ROS and increases GSH generation. AA also inhibites LPS-induced p-Akt in HCECs. These findings reveal that AA has anti-inflammation effects in LPS-stimulated HCECs.
