1 · What the graph read from it

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.

2 · The registry

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

purposeTo investigate the gene delivery efficiency of string-like PEG-b-PPA/DNA micellar nanoparticles in the liver after intravenous injection and intrabiliary infusion.

methodsPEG-b-PPA/DNA micellar nanoparticles were prepared in aqueous solution through spontaneous self-assembly between plasmid DNA and PEG(10K)-b-PPA(4K) or PEG(10K)-b-PP(13K) polymer. The stability of these micellar nanoparticles in different physiological media was evaluated by monitoring the particle size change of micellar nanoparticles with dynamic light scattering (DLS). The transfection efficiency of string-like PEG-b-PPA/DNA micellar nanoparticles in the liver was examined and compared with that of PPA/DNA nanoparticles after intravenous and intrabiliary infusion.

resultsThese PEG-b-PPA/DNA micellar nanoparticles exhibited unique string-like morphology under TEM. The stability of these string-like nanoparticles in salt-, serum- or bile- containing media was significantly improved compared with PPA/DNA nanoparticles. More importantly, these PEG-b-PPA/DNA nanoparticles mediated 10-fold higher transfection efficiency than PPA/DNA nanoparticles in rat liver when delivered via intrabiliary infusion. In addition, histopathological data revealed that the PEG-b-PPA/DNA nanoparticles induced minimal level of liver toxicity or damage.

conclusionsThese string-like PEG-b-PPA/DNA micelles can mediate efficient transgene expression in the liver after bile duct infusion, and they have great potential to be used as effective gene carriers for liver-targeted gene delivery.
