Objective To study the absorption and transportation of flavonoids in Herb Epimedii by using Caco-2 monolayer model. Methods Caco-2 cell monolayer model was used to study the bi-direction transport of icariin, epimedin A, epimedin B, epimedin C, and baohuoside Ⅰ. The concentration of the five flavonoids in cell culture medium was measured by UPLC and the apparent permeability coefficients (Papp) were calculated. Results The absorptive permeability coefficients (PAB) of icariin, epimedin A, epimedin B, epimedin C, and baohuoside Ⅰ were 5.91?10-7, 3.22?10-7, 2.76?10-7, 4.23?10-7, and 1.46?10-6 cm/s, respectively. Except baohuoside Ⅰ, the other four flavonodes had lower permeabilities, and the secretive permeabilities (PBA) of all the flavonoids were larger than their absorptive permeabilities. Among them, the PBA of baohuoside Ⅰ was 9.8 times as much as the PAB. Conclusion The results suggest that the intestinal absorption of the five flavonoids is lower, which might have efflux mechanism by transporters, and the absorption of monloglycoside (e.g. baohuoside Ⅰ) is better than that of diglycoside (e.g. icariin) and triglycoside (e.g. epimedin A, epimedin B, and epimedin C).

At present, most clinical thrombolytic drugs are plasminogen activators, which are highly dependent on the plasminogen level of the patient. Therefore, the efficacy of those drugs is restricted. Unlike the conventional thrombolytic plasminogen activator drugs, fibrinolytic drugs have direct fibrinolytic activity. Thus, fibrinolytic drugs can directly dissolve the thrombus, and its thromlysis efficacy is not restricted by the patients' plasminogen. This is a new type of thrombolytic drug with higher thrombolytic efficiency and safety, and has become one of the research hotspots at present. Although more and more agents that can be used as fibrinolytic drugs have been discovered, only a few of them can successfully be applied in clinical practice. The mainly underlying reason is the risk of bleeding. In this paper, based on the latest research progress of fibrinolytic drugs, the bleeding mechanisms and coping strategies of fibrinolytic drugs were systematically reviewed, five types of bleeding mechanisms of fibrinolytic drugs were summarized, and three types of coping strategies were proposed. We hope our work can provide theoretical basis for the development of safer and more efficient fibrinolytic drugs.
