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

backgroundTuina is an effective treatment for the decrease of skeletal muscle atrophy after peripheral nerve injury. However, the underlying mechanism of action remains unclear. This study aimed to explore the underlying mechanisms of tuina in rats with sciatic nerve injury (SNI).

methodsWe established an SNI rat model. After Tuina intervention, curative effects were evaluated by behavioral assessment, nerve function index, and muscle atrophy index (MAI). Pathological changes were observed by transmission electron microscopy and immunofluorescence. Insulin-like growth factor 1 (IGF-1), forkhead box O (FoxO) and p-FoxO levels were detected using enzyme-linked immunosorbent assay. Western blotting was performed to detect the expression of proteins involved in the PI3K/AKT signaling pathway.

resultBehavioral assessment, nerve function index, and MAI revealed that the tuina had significantly improved muscle atrophy after SNI compared with the SNI model group. Transmission electron microscopy showed that tuina improved muscle ultramicrostructure. CD31 immunofluorescence revealed that tuina improved microcirculation. Furthermore, we observed that tuina differentially regulated the levels of IGF-1, FoxO and p-FoxO, and the protein expression of p-Phosphoinositide 3-kinase (p-PI3K), p-AKT, and vascular endothelial growth factor in the anterior tibial muscle and soleus muscles.

conclusionTuina could effectively inhibit skeletal muscle atrophy via the microcirculation pathway in a rat model of SNI by regulating the expression of IGF-1 and FoxO. The underlying mechanism of action may involve the PI3K/Akt signaling pathway.
