Synergistic Neuroprotection of Artesunate and Tetramethylpyrazine in Ischemic Stroke, Mechanisms of Blood-Brain Barrier Preservation.

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
Artesunate (AS) and tetramethylpyrazine (TMP) have been proven to have therapeutic potential in ischemic stroke. Nevertheless, their synergistic treatment mechanisms and effectiveness remain unclear. A rat MCAO model was induced, and AS, combined with TMP, was administered intranasally to rats once a day for 3 days. The neurological severity scores, TTC staining, and H&E staining were implemented to analyze tissue injuries. Evans blue staining and immunohistochemistry of ZO-1, occludin, MMP-9, and TIMP-1 were implemented to evaluate the integrity of the blood-brain barrier (BBB). ELISA was used to detect the expression levels of inflammatory factors TNF-α and IL-10. TUNEL staining and the protein expression of Bax and Bcl-2 were used to evaluate the apoptosis of brain tissue cells. The core targets were predicted by network pharmacology and verified by the OGD/R cell model and siRNA in vitro. Results showed that nasal administration of AS and TMP significantly ameliorated ischemic-stroke-induced neurological dysfunction, BBB disruption, and cortical neuronal apoptosis. The protective mechanisms mainly included adjusting the expression and ratio of tight junction proteins TIMP-1 and MMP-9 in brain tissue, regulating the HIF-1α-VEGF pathway, and anti-inflammatory effects. This study provides experimental support for the further development and application of AS and TMP nasal combinations and provides the foundation for expanding the practical-application value of artemisinin and its derivatives.
