ABSTRACT

A novel sort of nano-component was extricated and isolated from Descurainiae Semen Carbonisatum (DSC), and its hemostatic component was considered through pharmacological experiments. A muffle furnace was used to prepare DSC at 250 ℃, 300 ℃ and 350 ℃, and the DSC dialysate at each temperature was obtained by the extraction and separation method. Low-resolution transmission electron microscopy (TEM) and high-resolution transmission electron microscopy (HR-TEM) were utilized to characterize the nano-components. Ultraviolet spectroscopy (UV-Vis), fluorescence spectroscopy (FL) and infrared spectroscopy (FTIR) were utilized to measure its optical characteristics and functional group information. The anti-hemorrhagic effects were evaluated by liver bleeding tests and the related hemostatic mechanisms of the obtained nano-components were further assessed by detecting blood coagulation and PLT quantity to discuss the hemostasis mechanism. The experiments complied with the Animal Ethics Committee of Beijing University of Chinese Medicine. TEM results showed that there was a novel type of nano-component in the DSC dialysate bag, which was named DSC nano-components (DSC-NCs). The experimental results of liver bleeding in mice showed that DSC-NCs prepared at 250 ℃, 300 ℃, and 350 ℃ could reduce the bleeding time of mice liver. Among them, DSC-NCs prepared at 350 °C had the best effect. In addition, DSC-NCs prepared at various temperatures can also reduce the prothrombin time (PT) value, increase the fibrinogen (FIB) value and the platelet (PLT) value to varying degrees. DSC-NCs have a certain hemostatic effect, which may be related to the activation of the exogenous coagulation system, the increase of FIB value and the increase of platelet content. This provides a new research direction for exploring the treatment of bleeding diseases, and provides a new perspective for the potential application of DSC-NCs in the medical field.

ABSTRACT

Houpo Wenzhongtang was contained in Neiwaishang bianhuolun.It was composed of seven medicinal materials of Magnoliae Officinalis Cortex(processed with ginger),Citri Reticulatae Pericarpium(remove white sac),Glycyrrhizea Radix et Rhizoma(processed with honey),Alpiniae Katsumadai Semen,Poria,Aucklandiae Radix and Zingiberis Rhizoma.It was a classic prescription for treatment of deficient cold of spleen and stomach,distention of chest and abdomen,autumn and winter guest cold crime stomach and feel pain at times by LI Dongyuan,who was a famous doctors in Jin-Yuan dynasties.It has been included in the Catalogue of Ancient Classical Prescription(The First Batch) issued by the State Administration of Traditional Chinese Medicine in 2018.This paper systematically reviewed the relevant research progress of Houpo Wenzhongtang from the aspects of famous doctors' theory,usage and dosage,chemical composition,quality analysis,pharmacology and toxicology,clinical application in database,and to provide a reference for further exerting the clinical application of this classical prescription.
