Study on the Anti-fatigue Effects of Polysaccharides from Erjing Formula.

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.
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
backgroundThe traditional Chinese recipe "Erjing Formula", composed of HuangJing and GouQi, is recognized for its tonifying and revitalizing properties, but the active components responsible for these effects are poorly explored. This study investigated the antifatigue effects of Erjing Formula polysaccharides (EJFP).
objectiveThe present study aimed to investigate the anti-fatigue effects of EJFP through weight-loaded swimming tests in mice.
methodsSPF-grade healthy male mice species KM mice were gavaged with EJFP and then subjected to a weight-loaded swimming test. Later, the levels of various biochemical indicators, including blood lactate (BLA), blood urea nitrogen (BUN), superoxide dismutase (SOD), malondialdehyde (MDA), muscle glycogen (MG), and hepatic glycogen (HG), were measured. The muscle tissue slices were analyzed using hematoxylin and eosin H&E) staining. Additionally, the expression levels of Kelch-like ECH-associated Protein 1 (Keap-1) and nuclear factor erythroid 2-related factor 2 (Nrf2) in the muscle tissue of each group were detected using Western Blotting.
resultsEJFP (Erjing Formula Polysaccharides) significantly increased swimming time (p ≤ 0.01), reduced oxidative stress markers and detrimental metabolites (BLA, BUN, and MDA), and elevated SOD, MG, and HG levels. Histologically, it improved muscle integrity. Nrf2 expression increased, indicating a relationship between antioxidant effects and antifatigue activity.
conclusionEJFP demonstrated anti-fatigue effects, mainly at moderate doses, by modulating the Nrf2/Keap1 pathway and improving glycogen and antioxidant levels. This is the first study to document the anti-fatigue effects of Erjing Formula polysaccharides, establishing a theoretical basis for practical applications in the development of anti-fatigue products.
