The mechanism of its effect on CVB3-RNA replication has been investigated by detection of beta-interferon (β-IFN) as well. Results showed that the copy numbers of CVB3-RNA as well as the histologic scores (necrosis) in myocardial tissues of infected-AM treated mice were significantly lower than those in infected and normal saline treated mice, suggesting that AM could inhibit the replication of CVB3-RVA,but its effect on CVB3-RNA replication had no correlation with induction of β-IFN.展开更多

Methods: A database was set up by collecting and sorting out the relevant literature, and the analysis was made with the complex network. Results: It was found that Bai Jie Zi (白芥子 Semen Sinapis Albae), Xi Xin (细辛 Herba Asari), Gan Sui (甘遂 Radix Euphorbiae Kansui) and Yan Hu Suo (延胡索 Rhizoma Corydalis) were used as the basic prescriptions of drugs, Feishu (BL 13), Dazhui (GV 14) and Shanzhong (CV 17) were selected as the basic prescription of points. Conclusion: The knowledge obtained from the complex networks on the basic prescriptions of drugs and points for point-application in summer to treat diseases with attacks in winter can provide a data support for working out operation norms and carrying on verification research.展开更多
