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

backgroundBerberine is a natural isoquinoline alkaloid possessing various pharmacological effects, particularly apparent in the treatment of diarrhea, but the underlying mechanism remains unclear. Smooth muscle myosin light-chain kinase (MLCK) plays a crucial role in the smooth muscle relaxation-contraction events, and it is well known that berberine can effectively depress the contraction of smooth muscle. Hence, whether berberine could inhibit MLCK and then depress the smooth muscle contractility might be researched.

objectiveThe purpose of this study is to investigate the effects of berberine on MLCK. Based on this, the contractility of gastro-intestine, catalysis activity of MLCK, and molecular docking are going to be evaluated. MATERIALS AND

methodsThe experiment of smooth muscle contraction was directly monitored the contractions of the isolated gastrointestine by frequency and amplitude at different concentration of berberine. The effects of berberine on MLCK were measured in the presence of Ca

resultsThe phosphorylation of myosin and the Mg

conclusionThe present work gives a deep insight into the molecular mechanism for the treatment of diarrhea with berberine, i.e., berberine could suppress the contractility of smooth muscle through binding to MLCK and depressing the catalysis activity of MLCK. SUMMARY: Berberine significantly reduced the amplitude of contraction in isolated duodenum and gastric strips in ratsBerberine inhibited the phosphorylated extents of MLC20 and Mg2+-ATPase activity of phosphorylated myosin induced by MLCKBerberine binds to the ATP binding site of MLCK by hydrophobic effect and hydrogen bondingBerberine may modulate contraction of smooth muscle by inhibiting MLCK.
