Protective effects of autologous bone marrow-derived mesenchymal stem cell transplantation on acute radioactive enteritis in Beagle dogs.

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
backgroundRadiation enteritis is a common complication of radiation therapy in which the surrounding normal intestinal tissue is damaged by ionising radiation, and there is no standard pharmacological prophylaxis or treatment regimen available. Mesenchymal stem cell transplantation can be used for radiation protection and the treatment of acute radiation injury, but its therapeutic mechanism of action remains unclear.
aimTo investigate the protective effects of autologous bone marrow-derived mesenchymal stem cell (ABMSC) transplantation on radiation-induced intestinal injury.
methodsA model of acute radioactive enteritis was established in dogs by applying abdominal intensity-modulated radiation at a single X-ray dose of 12 Gy. ABMSCs were transplanted into the mesenteric artery with the technology of femoral artery puncture and DSA imaging two days after radiation. Visual and histopathological changes of the experimental dogs were observed. Different kinds of cytokines from intestinal samples were tested using Quantibody Canine Cytokine Array method. Enzyme-linked immunosorbent assay (ELISA) was also used to evaluate the cytokines changes in serum.
resultsThe ABMSCs group showed significant improvements in survival status compared with the blank and saline treatment groups. Histological observations revealed that the former had lower histological scores than the later after treatment (
conclusionOur data suggest that transplantation of ABMSCs promotes intestinal recovery after acute radioactive injury in Beagle dogs. The cytokines of IL-10 and MCP-1 might play an important role in this process.
