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 further investigate the {ptin vitro} effects of an osteoprotective herbal formula "ELP" (Herba Epimedii, Fructus Ligustri Lucidi and Fructus Psoraleae) using seropharmacological approach.

methodsRats were fed with ELP or its individual component herbs for 2 days. The serum containing the postabsorbed ingredients of the herbal items were collected for cell culture using UMR106 cell, RAW264.7 cell and mesenchymal stem cell (MSC) isolated from the bone marrow of the rats. The effects of the herbal-containing serum on cell toxicity were detected by 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide assay; bromodeoxyuridine assay was conducted to measure the cell proliferation of UMR106 cell and MSC; cell activity was measured using colorimetric method, and mRNA expression of runt-related transcription factor 2 (Runx2), alkaline phosphatase (ALP) and osteopontin (OPN) of UMR106 and MSC as well as matrix metalloproteinase 9 (MMP-9), tartrate-resistant acid phosphatase (TRAP) and cathepsin K of RAW264.7 were analyzed using real-time reverse-transcription polymerase chain reaction.

resultsELP and its component serum exhibited no cytotoxic effects on the cells. The ELP-containing serum increased the proliferation of UMR106 cell and MSC by 25.7% and 14.4 %, respectively and the alkaline phosphatase activity of MSC was increased by 42.6%. On the contrary, it inhibited the RAW264.7 cell differentiation by 29.2 %. ELP serum upregulated the Runx2 expression of UMR and MSC by 1.18 fold and 1.27 fold, respectively. It also upregulated ALP and OPN expression in MSC by 1.69- and 2.12-fold, respectively. On the other hand, ELP serum down-regulated MMP-9 and cathepsin K expression of RAW264.7 cell by 0.46- and 0.36-fold, respectively.

conclusionsThe serum of the animals fed with ELP contains active ingredients which are effective in promoting osteogenesis and inhibiting osteoclastogenesis.
