RESUMEN
Succus Bambusae， regarded as the holy medicine for the treatment of phlegm by traditional Chinese medicine experts， has the functions of clearing heat and resolving phlegm， resuscitating and relieving convulsions. In clinical practice， it is mainly used to treat phlegm-heat cough， phlegm yellow and shortness of breath， stroke with exuberant phlegm and other syndromes. The research of its processing procedure and quality standard is the key issue to realize the process modernization and quality standardization of this traditional medicine resource. On the basis of literature research， this paper conducted the herbal textual research on Succus Bambusae， sorted out its medicinal history， and compared the advantages and disadvantages of its traditional and modern preparation procedure. Based on the historical records， it is pointed out that there are still many problems in the traditional and modern processing procedure of Succus Bambusae， such as low-yield processing procedure and extensive production technology that cannot meet the requirements of large-scale green manufacturing. At present， there are a lot of literature on the comparative study of the origin， variety and processing procedure of Succus Bambusae， but most of them are limited to the chemical components， and lack of in-depth study on its pharmacodynamic substance basis and mechanism. Meanwhile， the pharmacological effects of Succus Bambusae are mostly limited to antitussive and expectorant， and few other pharmacological effects have been reported. Based on the above analysis， it is suggested that the follow-up research work can be carried out from these five aspects：①Clarifying the original source， enriching and perfecting the medicinal resources. ②Standardizing the processing procedure， establishing relevant quality standards. ③Clarifying the pharmacological mechanism， strengthening the basic research on the pharmacological effect and clinical application. ④Inheriting ancient processing， researching and developing special preparation equipment and standardizing production operation rules. ⑤Comprehensive utilization of the by-products in preparation process.
RESUMEN
Plant-derived extracellular vesicles (EVs) are membranous vesicles secreted by plants, which include lipid bilayer as the basic framework and encapsulate various proteins, nucleic acid and other active substances. They play an important role in plant growth and development, tissue repair and self-defense. In recent years, extracellular vesicle-like nanoparticles (EVNs) are prepared from plant samples referring to the separation method of EVs and show unique functions. In this review, the above structures are collectively called plant-derived vesicles (PDVs). The biogenesis, separation and characterization methods, in vivo and in vitro properties of PDVs have been reviewed. The biomedical applications of PDVs as natural therapeutic agents and functional drug carriers are described, and finally some opinions on the existing problems and future prospect in this field are put forward.
RESUMEN
Visceral manifestation theory is that lung dominates Qi, breath, and governs ascent and dispersion. How to combine the theory of traditional Chinese medicine (TCM) with the modern physiology and pathology in modern scientific interpretation has been the focus of attention. Previous study found that most of the ventilating lung and releasing exterior drugs contained the pharmacodynamic substance related to adrenergic receptor (AR) signal transduction. The connotation of "lung governing ascent", such as controlling breath movement, transferring nutrients, spreading heat to regulate temperature, helping the heart to control blood circulation, coincided with the physiological function of the organ dominated by the AR-regulated sympathetic postganglionic fibers. Therefore, the hypothesis of "lung governing ascent" is closely related to AR pathway signal transduction. The correlation between the molecular mechanism of the modern physiology and pathology and pharmacodynamic substance basis was evaluated and expounded by the deduction of pulmonary modern biological theory based on ventilating lung and releasing exterior in this paper. So the guidance on the theory of visceral manifestation in TCM for the research and development of modern drugs should be expected fully. Ultimately, the application of lung governing ascent principle will be a profound meaning to guide the prevention and clinical treatment for a variety of refractory diseases caused by the change of environment, climate or lifestyle.
