Osteopontin attenuates inflammation via JAK2/STAT1 pathway in hyperglycemic rats after intracerebral hemorrhage.

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
Acute intracerebral hemorrhage (ICH) complicated by hyperglycemia is associated with aggravation of post-stroke inflammation, leading to exacerbation of brain edema and predicting poor neurological outcomes and higher mortality of patients. Osteopontin (OPN) is a neuroprotective glycoprotein, which is able to attenuate brain injury induced by hemorrhagic stroke. In the current study we investigated whether OPN will decrease the inflammatory post-ICH response as well as attenuate brain edema and neurological deficits in hyperglycemic rats. We employed a collagenase model of ICH on male Sprague-Dawley rats (n = 148) rats and 50% of Dextrose was injected intraperitoneally (i.p) 3 h after ICH (ICH + HG). Intranasal administration of recombinant OPN (rOPN) was performed 1 h after ICH. The development of brain injury was evaluated by brain water content (BWC) and neurological deficits, western blot and immunohistochemistry study. Small interfering ribonucleic acid (siRNA) for integrin-β1 receptor and a JAK2 agonist, Coumermycin A1 (C-A1), were used for detailed investigation of the molecular pathway. The administration of OPN (3 μg) significantly improved neurobehavior and increased expression of OPN and integrin-β1 receptor in the brain followed with decrease of neutrophil infiltration, JAK2, STAT1, TNF-a, IL-1b, MMP-9 and brain edema in the ICH + HG + OPN rats compared with ICH + HG rats. The effects of OPN were reversed by the intervention of intergrin-β1 siRNA and C-A1. In conclusion, rOPN attenuated ICH-induced brain inflammation in hyperglycemic rats, leading to attenuation of brain edema and improving neurological functions. Effects of rOPN were mediated at least partly by integrin-β1 induced inhibition of JAK2/STAT1 pathway.
