Project description:Xuesaitong injection (XST), a standardized patent Chinese medicine of Panax notoginseng roots (Sanqi in Chinese), has long been used for effective prevention and treatment of stroke in China. However, the mechanisms underlying its effects against ischemic stroke are still poorly understood. In this study, we focused on the polypharmacology of XST against ischemic stroke with a XST-regulated stroke network analysis. Male Sprague Dawley rat model of MCAO and reperfusion were administered XST for 7 days while the control group was not treated.

In this study, we focused on the polypharmacology of XST against ischemic stroke with a XST-regulated stroke network analysis. Male Sprague Dawley rat model of MCAO and reperfusion were administered XST for 7 days while the control group was not treated. Three conditions were compared with three replicates each. These are: (1) sham; (2) model (3) XST treatment. Whole genome microarray analysis was performed using Affymetrix rat Genome 230 2.0 chips.
Project description:Transitional Chinese herbal medicine has a long history of applications for anti-aging and longevity purposes, and in our patent formula Gancao Nurish-Yin (GCNY) decoction, all of the ingredients show antioxidant properties. However, in real clinical practice, extractions of herbs are rarely applied alone but are prescribed as integrated formula. In order to investigate whether GCNY possess anti-oxidation potential, we applied GCNY as a formula to treat rats in order to acquire medicated serum, which was then added on H2O2 (200 μM)-modeled human microglial cell line HMC-3 in comparison with its controls.
Project description:Chinese medicine is a complex system guided by traditional Chinese medicine (TCM) theories, which has proven to be especially effective in treating chronic and complex diseases. However, the underlying modes of action (MOA) are not always systematically investigated. Herein, a systematic study was designed to elucidate the multi-compound, multi-target and multi-pathway MOA of a Chinese medicine ,QSYQ, on myocardial infarction. Male Sprague Dawley rat model of myocardial infarction were administered QSYQ intragastrically for 7 days while the control group was not treated. The differentially expressed genes (DEGs) were identified from myocardial infarction rat model treated with QSYQ, followed by constructing a cardiovascular disease (CVD)-related multilevel compound-target-pathway network connecting main compounds to those DEGs supported by literature evidences and the pathways that are functionally enriched.
