AI Article Synopsis
- Pushen capsule is being researched for its potential effectiveness in treating ischemic stroke, a major cause of long-term disability, as its prior effects have not been established in this context.
- The study utilized various methods to analyze Pushen's impact on stroke model mice, identifying key active ingredients like tricin and quercetin that bind to specific transcription factors involved in the cAMP signaling pathway.
- Results showed that Pushen reduced infarct volume, improved the blood-brain barrier, and positively influenced gut microbiota, indicating its promising clinical applications for stroke treatment.
Article Abstract
Background: As a leading cause of long-term disability, ischemic stroke urgently needs further research and drug development. Pushen capsule (Pushen) has been commonly applied in clinical treatment for relieving headaches, dizziness, and numbness. However, the effects of Pushen on ischemic stroke have not been revealed yet.
Purpose: To assess the efficiency of Pushen in ischemic stroke and identify its potential therapeutic targets and active ingredients for treating ischemic stroke.
Study Design And Methods: Behavioural experiments, Triphenyltetrazolium chloride (TTC) staining, Magnetic resonance imaging (MRI), and immunofluorescence staining were performed to examine the efficiency of Pushen in stroke model mice. The potential mechanism and active ingredients of Pushen were assessed by transcriptome, 16S rDNA sequencing, metabonomics, and network pharmacology. Finally, the targets were validated by RT-PCR, chromatin immunoprecipitation (ChIP), ELISA, and molecular docking methods.
Results: Pushen had several effects on stroke model mice, including reducing the infarct volume, improving the blood‒brain barrier (BBB), and promoting functional restoration. Furthermore, the network pharmacology, LC-MS/MS, and molecular docking results revealed that tricin, quercetin, luteolin, kaempferol, and physcion were identified as the key active ingredients in Pushen that treated ischemic stroke. Mechanistically, these key ingredients could bind with the transcription factor c-Myc and thereby regulate the expression of Adora2a, Drd2, and Ppp1r1b, which are enriched in the cAMP signaling pathway. Additionally, Pushen improved the gut microbiota dysbiosis and reduced inosine levels in feces and serum, thereby reducing Adora2a expression in the brain.
Conclusions: Our study confirmed that Pushen was effective for treating ischemic stroke and has promising clinical applications.

Ischemic stroke is caused by blockage of blood vessels in brain, affecting normal function. The roles of Signal Transformer and Activator of Transcription 1 (STAT1), CASP8, and MYD88 in ischemic stroke and its care are unclear. The ischemic stroke datasets GSE16561 and GSE180470 were found from the Gene Expression Omnibus database.

Occlusion of the distal internal carotid artery can simulate a proximal occlusion of its cervical tract on CT angiography in patients with acute ischemic stroke, that is, pseudo-occlusion. As true and false carotid occlusions can present similarly on non-invasive imaging in patients undergoing endovascular treatment for stroke, our study aimed to evaluate clinical and technical differences of these conditions and the possible consequences of a misdiagnosis. We retrospectively reviewed consecutive patients who underwent mechanical thrombectomy for acute ischemic stroke at a single center between July 2015 and May 2022 and included patients with absent opacification of the cervical carotid artery on CT-angiography.

Ischemic stroke is the most common cerebrovascular disease and the leading cause of permanent disability worldwide. Recent studies have shown that stroke development and prognosis are closely related to abnormal tryptophan metabolism. Here, significant downregulation of 3-hydroxy-kynurenamine (3-HKA) in stroke patients and animal models is identified.

Ischemic stroke is a worldwide disease with high mortality and morbidity. Kv7/KCNQ channels are key modulators of neuronal excitability and microglia function, and activation of Kv7/KCNQ channels has emerged as a potential therapeutic avenue for ischemic stroke. In the present study, we focused on a new Kv7/KCNQ channel opener QO-83 on the stroke outcomes and its therapeutic potential.
