Association between glucose-regulated protein and neutrophil apoptosis in severe acute pancreatitis.

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
objectiveThis study aimed to investigate the role of glucose regulated protein 78 (GRP-78) in the apoptosis of neutrophils in rats with severe acute pancreatitis.
methodsA total of 54 SD male rats were randomly assigned into 2 groups: sham group (n=24) and pancreatitis group (n=30). Severe acute pancreatitis was induced by retrograde cholangiopancreatography injection of sodium taurocholate. Rats were sacrified at 3 h, 6 h and 12 h after injection. In control group, rats received laparotomy, but the pancreates remained intact. The serum amylase was detected at different time points, and flow cytometry was done to detect the apoptosis of neutrophils. Proteins were extracted from neutrophils and subjected to detection of GRP78 and Mcl-1 expression by Western blot assay. HE staining was performed for pathological scoring of the pancreas.
resultsThe serum amylase in pancreatitis group increased markedly when compared with control group (P<0.01). In SAP group, the serum amylase increased gradually over time (P<0.01). HE staining showed a lot of inflammatory cells and infiltration of red blood cells and the apoptosis rate of neutrophils reduced gradually (P<0.01). Western blot assay showed the protein expression of GRP-78 and Mcl-1 increased in neutrophils over time.
conclusionIn rats with SAP, the apoptosis rate of neutrophils reduced over time, which may be associated to the stress induced expression of GRP78 and subsequent activation of Mcl-1 resulting in suppression of neutrphil apoptosis over time.
