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

Hemorrhagic shock (HS) due to major trauma predisposes the host to the development of acute lung inflammation and injury. The lung vascular endothelium is an active organ that plays a central role in the development of acute lung injury through generating reactive oxygen species and synthesizing and releasing of a number of inflammatory mediators, including leukocyte adhesion molecules that regulate neutrophils emigration. Previous study from our laboratory has demonstrated that in a setting of sepsis, toll-like receptor-4 (TLR4) signaling can induce TLR2 expression in endothelial cells (ECs), thereby increasing the cells' response to TLR2 ligands. The present study tested the hypothesis that TLR4 activation by HS and the resultant increased TLR2 surface expression in ECs might contribute to the mechanism underlying HS-augmented activation of lung ECs. The results show that high-mobility group box 1 (HMGB1) through TLR4 signaling mediates HS-induced surface expression of TLR2 in the lung and mouse lung vascular endothelial cells (MLVECs). Furthermore, the results demonstrate that HMGB1 induces activation of NAD(P)H oxidase and expression of ICAM-1 in the lung, and MLVECs sequentially depend on TLR4 in the early phase and on TLR2 in the late phase following HS. Finally, the data indicate an important role of the increased TLR2 surface expression in enhancing the activation of MLVECs and augmenting pulmonary neutrophil infiltration in response to TLR2 agonist peptidoglycan. Thus, induction of TLR2 surface expression in lung ECs, induced by HS and mediated by HMGB1/TLR4 signaling, is an important mechanism responsible for endothelial cell-mediated inflammation and organ injury following trauma and hemorrhage.
