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

objectiveEsketamine (ESK), an intravenous anesthetic, exerts antidepressant effects; however, the antidepression mechanism is not clear. The aim of this study was to explore whether microglial cannabinoid type 2 (CB2) receptor and protein kinase C (PKC) are involved in the antidepressant effects of ESK.

methodsIn this investigation, lipopolysaccharide (LPS) was used to stimulate BV-2 microglia to mimic neuroinflammation. An enzyme-linked immunosorbent assay (ELISA) and Griess reagent kits were used to determine cytokine and nitrite concentrations in the medium. CB2, inducible nitric oxide synthase (iNOS) and nuclear factor (NF)-κB (p65) protein expression were evaluated by immunocytochemistry and western blot analysis.

resultsCompared with the control, LPS enhanced proinflammatory factor and nitrite concentration in the medium, upregulated iNOS and NF-κB (p65) expressions, and coadministration of ESK decreased proinflammatory cytokine and nitrite levels, and downregulated iNOS and NF-κB (p65) expression. Moreover, ESK exposure enhanced CB2 receptor expression; coadministration of the CB2 receptor antagonist AM630 or the PKC inhibitor chelerythrine (Che), however, markedly blocked the anti-inflammatory effect of ESK in reducing cytokine and nitrite concentration, and downregulating iNOS and NF-κB (p65) expression.

conclusionsThese observations demonstrated that the microglial CB2-PKC pathway mediates ESK-induced anti-inflammation in LPS-stimulated microglial cells.
