RÉSUMÉ
Objective Based on the theory of"lung governs the skin and hair"in"Yellow Emperor's Inner Classic",this paper analyzes the medication rules of whitening and freckle-removing.The aim of this study is to provide reference for the clinical practice of traditional Chinese medicine(TCM)theory and the medication in TCM cosmetics.Methods"Chinese Medical Classics"was used to search the records of whitening and freckle-related drugs.The frequency,nature,flavor,meridian tropism and compatibility laws of TCM for whitening and freckle-removal were analyzed by statistics and association rules.The network pharmacology research was used to analyze the whitening and freckle-removing effects and mechanisms of high-frequency drugs.Then,the potential active ingredients were analyzed.The whitening and anti-freckle effect was verified through cytotoxicity experiments and melanin content detection.Results A total of 171 external prescriptions were selected in eligible articles,including 261 Chinese medicinals,most of which were pungent and belong to the lung meridian.The most frequently used Chinese medicinals was"Erbai Yixin"(EBYX,Angelicae Dahuricae Radix,Typhonii Rhizoma,Asari Radix et Rhizoma).Network pharmacological analysis showed that the core targets of EBYX for whitening and removing freckles are TP53,EGFR,ALB,etc.,which are mainly involved in oxygen perception and response,skin immune regulation,skin cell growth,differentiation,stress,inflammatory response,and other biological processes.Based on the results of molecular docking,biological analysis proved that the active ingredients of EBYX are chrysophanol,gallic acid and caffeic acid,which have inhibitory effects on the proliferation of melanoma cells and melanin production.Conclusion Most of the ancient prescriptions for whitening and removing freckles are pungent and belong to the lung meridian,which embodies the theory of"lung governs the skin and hair".The high-frequency drug EBYX may play a role by regulating skin redox,immunity and inflammation.The active ingredients of EBYX have an inhibitory effect on melanin formation.This study enriches the scientific connotation of TCM whitening and freckle-removing prescriptions based on the theory of"lung governs the skin and hair",realizes interdisciplinary integration and provides support for the modernization of TCM.
RÉSUMÉ
Objective To investigate the effects of Qinma Formula on endogenous anti-inflammatory system in rats with chronic obstructive pulmonary disease (COPD); To discuss its mechanism of action. Methods Rat models of COPD were made by modified smoked lipopolysaccharide method. 70 healthy SPF male Wistar rats were randomly divided into normal group, model group, Western medicine control group (aminophylline group), TCM medicine control group (Liujunzi Decoction group) and Qinma Formula high-, medium-, and low-dose groups, with 10 rats in each group. Each medication group was given relevant medicine for gavage. The pathological changes of lung tissue were observed under light microscope; the alveolar lavage fluid (BALF) and venous blood were collected and the related indexes were tested; the levels of serum IL-1β, IL-6 and IL-10 were detected by ELISA. Results Compared with normal group, BALF white blood cells, neutrophils, macrophages, lymphocyte, hemoglobin and platelet count in rats of model group increased significantly (P<0.05). Compared with the model group, BALF white blood cells, neutrophils, and macrophages in rats of Qinma medium- and high-dose groups and Liujunzi Decoction group decreased significantly (P<0.05); white blood cells, hemoglobin, and platelet count in rats of Qinma medium-, high-dose groups and aminophylline group decreased significantly (P<0.05); levels of IL-1β and IL-6 in serum decreased significantly (P<0.05); level of IL-10 in serum increased significantly (P<0.05). Conclusion Qinma Formula can effectively inhibit the inflammatory response through the regulation of inflammatory response-related cytokines.
