[Effect of propofol on apoptosis of PC12 cells under hypoxic condition and the mechanism].
Article in Nan fang yi ke da xue xue bao = Journal of Southern Medical University, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo investigate the mechanism by which propofol exposure causes PC12 cell apoptosis under hypoxic conditions.
methodsPC12 cells were exposed to room air, 35% oxygen, or 5% oxygen (hypoxia) for 24 h in the presence of either 10 µmol/L lipid emulsion or 10 µmol/L propofol. After the treatments, the cell apoptosis was measured by flow ceytometry, and the level of reactive oxygen species (ROS) and the activity of superoxide dismutase (SOD) were evaluated.
resultsIn room air, PC12 cells treated with propofol showed increased apoptosis rate and ROS production as compared with the cells treated with the lipid emulsion; propofol treatment of the cells exposed to 35% oxygen showed obvious enhancement of the apoptosis rate, ROS production and SOD activity. Under the hypoxic condition, propofol treatment even further increased the apoptosis rate, ROS production and SOD activity. Lipid emulsion caused no such changes in cells exposed to room air, 35% oxygen or 5% oxygen.
conclusionUnder hypoxic conditions, propofol can cause apoptosis in PC12 cells by inducing oxidative stress injury.
