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 the effect of slow transit constipation (STC) and spleen deficiency on gut microbiota, and the mechanism underlying the action that the positive drug Maren Runchang (MR) alleviates STC.

methodsSTC was induced, using the cathartic method of Senna and the hunger-fullness disorder method, in ICR mice; one group of model mice was treated with MR (6.24 g/kg). The changes in the general condition, fecal parameters, D-xylose content in the serum, intestinal propulsion rate, and histopathology of the colon were assessed after STC induction in the control, model, and MR groups. Fecal microbiota transplantation (FMT) was performed from STC mice into pseudo germ-free mice. Changes in the contents of substance P (SP), vasoactive intestinal peptide (VIP), and gut microbiota in STC mice and pseudo germ-free mice were assessed after FMT.

resultsCompared with the control group, the model mice showed the following results: the time of the first black stool was significantly longer ( 0.01), the number and weight of black stools were significantly reduced within 6 h ( 0.05), the D-xylose content in the serum was significantly reduced ( < 0.05), the intestinal propulsion rate decreased ( < 0.01), the content of VIP in colon tissue significantly increased ( < 0.05), and SP content in the colon tissue significantly decreased ( < 0.01); moreover, the colon showed significant inflame-mation and injury. Furthermore, the abundance of Firmicutes was increased, the abundance of Bacteroides decreased, and the abundance of decreased, while the abundance of the conditional pathogenic bacteria and Klebsiella increased. However, after treatment with MR, the time of the first black stool decreased (0.01), the number of black stools within 6 h increased, and the intestinal propulsion rate increased ( < 0.05). Moreover, the content of D-xylose in the serum and the content of VIP in colon tissue significantly decreased ( < 0.05), the content of SP in colon tissue significantly increased ( < 0.01), and colon inflammation significantly improved. Additionally, the abundance of Firmicutes decreased, and the abundance of Bacteroides increased. The abundance of increased, and the abundance of decreased. In the model + FMT group, compared with control + FMT group, the content of VIP in colon tissue decreased ( < 0.05), the content of SP in colon tissue significantly increased ( < 0.01), and the abundance of probiotics, such as , decreased. In the MR + FMT group, compared with the model + FMT group, the content of VIP in colon tissue increased, the content of SP in colon tissue significantly decreased ( < 0.01), and the abundance of probiotics increased.

conclusionsSTC mice with spleen deficiency show a decreased abundance of beneficial bacteria, such as , and an increased abundance of the conditional pathogenic bacteria . Furthermore, the mechanism of action of MR in treating STC may involve the regulation of intestinal movement, reduction of intestinal inflammation, elevation of intestinal absorption, and regulation of gut microbiota.
