AIM: To clarify the possible mechanism of decrease in coronary flow (CF) after long-term hypothermic storage of the isolated rat hearts. METHODS: The isolated rat hearts preserved in different solutions (SDMC-1,2 S., Stanford S., Collin's S.) at 0℃ for 8 hours were reperfused with 5-hydroxytryptamine (5-HT)(10 -4 mmol/L) and adenosine(Ade)(5 mmol/L) respectively, and the coronary flow(CF), coronary vascular resistance(CVR) and the weight of heart were measured before and after reperfusion. RESULTS: CF decreased while CVR increased in all groups after storage-reperfusion. When endothelium-dependent vasodilator (5-HT) was used, CF in SDMC-2 group was highly increased and CVR decreased. Whereas CF was significantly decreased and CVR increased in Collin's group( P

Network pharmacology is an emerging discipline based on the Disease-Gene-Drug multilevel network. And it has been used to forecast the drug targets and improve the efficiency of drug discovery. Its research ideas are similar to the overall efficacy of traditional Chinese medicine (TCM), which attracts more and more medical re-searchers to look for the joint point of TCM and network pharmacology. A series of approaches on disease-related genes, predicting the information of target and active ingredients of TCM emerge. In this paper, the network pharma-cology research tools, databases and their applications were summarized and introduced. This paper also proposed scientific strategies to separate active ingredients of TCM using network pharmacology, so as to improve the efficiency and speed of finding active ingredients of TCM.
