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

objectiveTo investigate whether the administration of the ultra-filtration extract from Danggui Buxue Decoction (EDBD) was able to protect cardiomyocytes from oxidative injury of rats induced by hydrogen peroxide (H(2)O(2)) and its potential mechanism.

methodsMyocardial cells from 1- to 2-day-old neonatal rats were cultured in Dulbecco's modified Eagle's medium low-glucose and Ham's F12 medium (1:1), and the cellular injury was induced by H(2)O(2). The ultra-filtration extract mixture from Angelica sinensis and Hedysarum polybotrys was given in three doses of 3.75, 7.5, and 15 mg/mL. Morphological changes of cardiomyocytes were observed by microscope. Survival rate of myocardial cells was assessed using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The cardiomyocyte damages were estimated by detecting lactate dehydrogenase (LDH) and creatine kinase (CK) releases in the medium, superoxide dismutase (SOD) activities, and intracellular malondialdehyde (MDA) and myeloperoxidase (MPO) contents. The levels of caspase-3 and heat shock protein 70 (hsp70) mRNA expression in cardiomyocytes were measured by reverse transcription polymerase chain reaction.

resultsThe EDBD could protect the cardiomyocytes from H(2)O(2) injury in a dosedependent manner (3.75, 7.50, and 15.00 mg/mL). The EDBD could significantly decrease LDH and CK leakages and intracellular MDA and MPO contents, increase SOD activity, up-regulate hsp70 expression, and down-regulate caspase-3 expression.

conclusionThe EDBD has protection on cardiomyocytes injured by H(2)O(2) through improving cell antioxidant ability, up-regulating hsp70 expression, and inhibiting caspase-3 activity.
