Abstract:
OBJECTIVE：To explore the medication rul e of Glycyrrhiza uralensis -containing antitussive prescriptions （GUAP）， and to provide reference for the research and development of new antitussive drugs. METHODS ：The GUAP were collected from 2015 edition of Chinese Pharmacopoeia （part Ⅰ）. The information of prescription name ，composition，flavor and meridian tropism，and functional indications were input into Excel 2018 software to establish the database. The frequency of traditional Chinese medicine （TCM）was analyzed statistically. Cluster analysis was performed for high frequency TCM （frequency≥15）in GUAP by using SPSS Statistics 23.0 software；Apriori algorithm and association rules of SPSS Modeler 18.0 software were used to analyze the drug combination of high-frequency TCM in GUAP （support degree ≥15％，confidence degree ≥70％，lift degree ≥1）. New GUAP was sorted. Totally 60 mice were divided into model group （normal saline ），positive group （Codeine phosphate tablet ， 5 mg/kg），New prescription low-dose ，medium-dose and high-dose groups （1.17，5.83，11.67 g/kg，by extractum ），with 12 mice in each group. They were given relevant medicine intragastricaaly once a day ，for consecutive 7 d. 1 h after last medication ，cough was induced by ammonia in mice for 30 seconds；the latent period of cough and the frequency of cough within 2 min were recorded，and the cough inhibition rate was calculated. RESULTS ：Totally 73 prescriptions involved 194 kinds of TCM ，with 11 ingredients of high-frequency TCM （G. uralensis ，Platycodon grandiflorus ，Semen Armeniacae ，Citrus reticulate ，Ephedra sinica ， Gypsum fibrosum ，Scutellaria baicalensis ，Mentha haplocalyx ，Pinellia ternate ，Poria cocos ，Peucedanum praeruptorum ），which were mainly pungent and mostly belonged to lung meridian. High-frequency TCM could be grouped into 5 categories. There were 7 two-item association rules （such as E. sinica →Semen Armeniacae ，G. fibrosum →Semen Armeniacae ）and 10 three-item association rules （such as G. fibrosum -Semen Armeniacae →E. sinica ，C. reticulate -P. grandiflorus →Semen Armeniacae ）. New GUAP contained G. uralensis ，P. grandiflorus ，Semen Armeniacae ，E. sinica ，C. reticulate ，G. fibrosum （mass ratio 1 ∶ 2 ∶ 2 ∶ 2 ∶ 3 ∶ 4）. Compared with model group ，the latent period of cough was prolonged and the frequency of cough within 2 min was decreased significantly in positive group and new prescription low-dose ，medium-dose and high-dose groups （P＜0.01）. Compared with positive group ，latent period of cough was shortened significantly in new prescription low-dose and medium-dose groups ，while the frequency of cough within 2 min was increased （P＜0.05 or P＜0.01）；but there was no significant difference in latent period of cough， the frequency of cough within 2 min， cough inhibitory rate of new prescription high-dose group （P＞0.05）. CONCLUSIONS：The new antitussive prescription was summarized by analyzing the medication rule of GUAP ，and was verified to have good antitussive effect ，which can provide reference for the development of new antitussive drugs.
