Annao Pingchong decoction attenuates oxidative stress and neuronal apoptosis following intracerebral hemorrhage via RAGE-NOX2/4 axis.
Article in Frontiers in neuroscience, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It has been retracted, and should not be counted. Not yet cited in PubMed.
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
Background: Intracerebral hemorrhage (ICH) is a severe condition associated with high mortality and disability rates. Oxidative stress plays a critical role in the development of secondary brain injury (SBI) following ICH. Previous research has demonstrated that Annao Pingchong decoction (ANPCD) treatment for ICH has antioxidant effects, but the exact mechanism is not yet fully understood. Objective: This study aimed to investigate the neuroprotective effects of ANPCD on oxidative stress and neuronal apoptosis after ICH by targeting the receptor for advanced glycation end products (RAGE)-NADPH oxidase (NOX) 2/4 signaling axis. Methods: The research involved the creation of rat ICH models, the mNSS assay to assess neurological function, Nissl staining to evaluate neuronal damage, and biochemical assays to measure oxidative and antioxidant levels. The expression of RAGE-NOX2/4 axis proteins was analyzed using western blotting and immunofluorescence, while neuronal apoptosis was assessed with TUNEL staining. Furthermore, after performing quality control of drug-containing serum using UPLC-MS/MS, we employed an Results: The findings indicated that ANPCD improved neurological deficits, reduced neuronal damage, decreased ROS and MDA levels, and increased the activities enzymatic activities of SOD, CAT, GSH and GPX. Additionally, it suppressed the RAGE-NOX2/4 signaling axis and neuronal apoptosis. Conclusion: ANPCD exhibits neuroprotective effects by inhibiting the RAGE-NOX2/4 signaling axis, thereby alleviating neuronal oxidative stress and apoptosis following ICH.
