Relationship between expression of triggering receptor-1 on myeloid cells in intestinal tissue and intestinal barrier dysfunction in severe acute pancreatitis.
Article in World journal of emergency medicine, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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.
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
backgroundTriggering receptor expressed on myeloid cells-1 (TREM-1) in the intestine was upregulated and correlated with disease activity in inflammatory bowel diseases. Membrane-bound TREM-1 protein is increased in the pancreas, liver and kidneys of patients with severe acute pancreatitis (SAP), suggesting that TREM-1 may act as an important mediator of inflammation and subsequent extra-pancreatic organ injury. This study aimed to investigate the relationship between the expression of TREM-1 in intestinal tissue and intestinal barrier dysfunction in SAP.
methodsSixty-four male Wistar rats were randomly divided into a sham operation group (SO group, n=32) and a SAP group (n=32). A SAP model was established by retrograde injection of 5% sodium deoxycholate into the bile-pancreatic duct. Specimens were taken from blood and intestinal tissue 2, 6, 12, and 48 hours after operation respectively. The levels of D-lactate, diamine oxidase (DAO) and endotoxin in serum were measured using an improved spectro-photometric method. The expression levels of TREM-1, interleukin-1β (IL-1β), and tumor necrosis factor-α (TNF-α) mRNA in terminal ileum were detected by real-time reverse transcription-polymerase chain reaction (RT-PCR). Specimens of the distal ileum were taken to determine pathological changes by a validated histology score.
resultsThe serum levels of D-lactate, DAO and endotoxin were significantly increased in each subgroup of SAP compared with the SO group (P<0.01, P<0.05). The expression levels of TREM-1, IL-1β and TNF-α mRNA in the terminal ileum in each subgroup of SAP were significantly higher than those in the SO group (P<0.01, P<0.05). The expression level of TREM-1mRNA was positively correlated with IL-1β and TNF-α mRNA (r=0.956, P=0.044; r=0.986, P=0.015), but the correlation was not found between IL-1β mRNA and TNF-α mRNA (P=0.133). Compared to the SO group, the pathological changes were aggravated significantly in the SAP group.
conclusionsThe expression level of TREM-1 in intestinal tissue of rats with SAP was elevated, leading to the release of inflammatory mediators and intestinal mucosal injury. This finding indicates that TREM-l might play an important role in the development of intestinal barrier dysfunction in rats with SAP.
