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

backgroundSanguisorbae Radix (SR) is a well-known herbal medicine used to treat inflammatory disease and skin burns in Asia. In addition, it is used to treat many types of allergic skin diseases, including urticaria, eczema, and allergic dermatitis. SR has been reported to exhibit anti-wrinkle, anti-oxidant, and anti-contact dermatitis bioactivities.

methodsIn this study, we investigated the mechanism underlying the anti-inflammatory effects of SR water extract (WSR) using human keratinocyte (HaCaT) cells and BALB/c mouse bone marrow-derived mast cells (BMMCs). Viability assays were used to evaluate non-cytotoxic concentrations of WSR in both BMMCs and HaCaT cells. To investigate the effect of WSR treatment on the degranulation of IgE/Ag-activated BMMCs, we measured the release of β-hexosaminidase (β-HEX). We determined the production of pro-inflammatory chemokines including thymus and activation regulated chemokine (TARC; CCL17), regulated on activation, normal T-cell expressed and secreted (RANTES; CCL5), macrophage-derived chemokine (MDC; CCL22), and interleukin 8 (IL-8; CXCL8) in stimulated human keratinocytes. The ability of WSR to reduce the expression of pro-inflammatory marker proteins was evaluated by Western blotting in HaCaT cells stimulated with tumor necrosis factor (TNF)-α/interferon (IFN)-γ.

resultWSR inhibited IgE/Ag-activated mast cell degranulation in BMMCs. Treatment with various concentrations of WSR decreased β-HEX release in a dose-dependent manner with an IC50 of 27.5 μg/mL. In keratinocytes, WSR suppressed TNF-α/IFN-γ-induced chemokine production and pro-inflammatory molecules via a blockade STAT-1, Jak-2, p38, and JNK activation.

conclusionsThis results demonstrate that WSR inhibits degranulation of IgE/Ag-activated mast cells and inhibits the production of pro-inflammatory chemokines by suppressing the phosphorylation of p38 and JNK in HaCaT cells.
