This study determined the extraction rates of indirubin in Indigo Naturalis by ethanol reflux extraction method and water extraction method. The pharmacodynamic study against cough induced by ammonia water in the mouse model and the cough induced by citric acid in the guinea pig model were performed to optimize the extraction process of the sovereign medicinal Indigo Naturalis and the whole prescription of Children's Qingfei Zhisou Syrup. The extraction rate of indirubin by the ethanol reflux method was 51.89%, and indirubin was not detected in the product of water extraction. Two samples of Children's Qingfei Zhisou Syrup prepared with different methods can prolong the incubation period of cough and suppress the frequency of coughs in pharmacodynamic experiments. In terms of prolonging the incubation period of cough, the two samples prepared with different methods had no significant difference. In terms of reducing the frequency of coughs, the high-dose Five kinds of ethanol extracts such as indigo naturalis and three kinds of water extracts such as gypsum had better effect against the citric acid-induced cough of guinea pigs than other samples(P<0.05). The extraction rate of indirubin in Children's Qingfei Zhisou Syrup sample prepared with ethanol was higher than that with water. The two samples of Children's Qingfei Zhisou Syrup prepared with the two methods showed good antitussive effects. The sample prepared with 5 ingredients(including Indigo Naturalis) extracted with ethanol and 3 ingredients(including Gypsum Fibrosum) extracted with water had better alleviation effect on the citric acid-induced cough of guinea pig than the whole water extract sample. In conclusion, the optimum extraction scheme is ethanol extraction for 5 ingredients including Indigo Naturalis in combination with water extraction for 3 ingredients including Gypsum Fibrosum, and the Children's Qingfei Zhisou Syrup produced in this manner has better antitussive efficacy.

Introduction: Ophiopogonanone B is a potent component of Qinbai Qingfei-concentrated pills (Qinbai), a new traditional Chinese medicine developed by our hospital for the treatment of pneumonia in children. We aim to study how ophiopogonanone B influences the expression of transient receptor potential anchor protein 1 (TRPA1), substance P (SP), and calcitonin gene-related peptide (CGRP) to treat coughing in -infected mice.
Methods: Ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS) was used to detect ophiopogonanone B.

Since the coronavirus disease 2019 (COVID-19) outbreak, although have controlled, severe acute respiratory syndrome coronavirus 2 is constantly mutating and affects people's health. FDA has approved Paxlovid and Molnupiravir for COVID-19 treatment, however, they have not been approved for children under 12 years old. Therefore, it is urgent to explore new drugs for treating COVID-19 in children.

Objective: Qingfei Tongluo Plaster (QFP), an improved Chinese medicine hospital preparation, is an attractive treatment option due to its well clinical efficacy, convenience, economy, and patient compliance in the treatment of respiratory syncytial virus (RSV) pneumonia. The aim of this study was to investigate the efficacy mechanism of QFP on RSV rats from the perspective of alleviating lung inflammation and further explore the changes of serum metabolites and metabolic pathways in RSV rats under the influence of QFP.
Methods: This study used network pharmacological methods and molecular docking combined with molecular biology and metabolomics from multi-dimensional perspectives to screen and verify the therapeutic targets.
