Background: Qilong capsule (QLC) is a traditional Chinese medicine
commonly used to treat ischemic stroke (IS). But the pharmacodynamic
mechanism of QLC is not clear. Method: we used an existing zebrafish
model to explore the protective mechanism of QLC on IS. We treated
normally-developing zebrafish larvae with QLC and ponatinib 2 days post
fertilization, and used the area of cerebral vascular thrombosis, red
blood cell staining intensity, and brain cell apoptosis to quantitate
QLC efficacy against IS. Real-time quantitative polymerase chain
reaction (qPCR) was used to detect changes in the expression of genes
involved in coagulation, inflammation, vascular endothelium, and
apoptosis. Result: We found that QLC reduced the area affected by
ponatinib-induced cerebral vascular embolism, erythrocyte staining
intensity, and the number of apoptotic brain cells. qPCR showed that QLC
inhibited the expression of genes related to coagulation, inflammation,
and apoptosis. Conclusion: QLC had a significant protective efficacy in
ponatinib-induced IS.
