Objective

2

To collect common prescriptions from multiple channels based on the mainstream guidance materials combined with ancient books to provide references for the selection principles of common prescriptions in clinical practice guidelines of traditional Chinese medicine （TCM） and western medicine.

Method

2

With the research on the selection of commonly used prescriptions in Clinical Practice Guidelines of Chinese and Western Medicine for Cough in Children as an example，the nation-recommended Schedule Ⅲ drugs and prescriptions for cough in children in the clinical diagnosis and treatment guidelines of TCM （TCM and western medicine）/expert consensus/clinical pathway/diagnosis and treatment protocols，three TCM pediatric textbooks， the experience of famous experts， and ancient books were searched for the establishment of a prescription database and analysis of medication regularity.

Result

2

The results showed that there were 71 commonly used prescriptions for the treatment of cough in children. The top 3 clinically indicated syndromes were the syndrome of phlegm-heat blocking the lung，the syndrome of wind-heat invading the lung，and the syndrome of wind-cold attacking the lung，and the top 5 efficacies corresponding to high-frequency drugs were reliving cough and dyspnea， clearing heat/resolving phlegm， dispersing wind/dissipating cold， clearing heat/purging fire， and dispersing wind/dissipating heat. The most commonly used Chinese medicines included Armeniacae Semen Amarum， Platycodonis Radix， Bolbostemmatis Rhizoma， Ephedrae Herba， Scutellariae Radix， Pinelliae Rhizoma， and Citri Reticulatae Pericarpium. Some drugs showed high internal correlations with Armeniacae Semen Amarum and Platycodonis Radix. There were 228 prescriptions for the treatment of cough in children based on the ancient books in the Chinese Medical Code. The most commonly used Chinese medicines were Pinelliae Rhizoma， Armeniacae Semen Amarum， Ginseng Radix et Rhizoma， Poria， Citri Reticulatae Pericarpium， Platycodonis Radix， Zingiberis Rhizoma Recens， and Bolbostemmatis Rhizoma. The top 5 efficacies corresponding to high-frequency drugs were dispersing wind/dissipating cold， relieving cough and dyspnea， clearing heat/resolving phlegm， warming cold/resolving phlegm， and tonifying Qi. Some drugs showed high internal correlations with Pinelliae Rhizoma and Platycodonis Radix. As revealed by the comparison of ancient and modern medication， the medication principles could be roughly classified into two categories： ventilating the lung/descending Qi and resolving phlegm. In ancient medication， the drugs for cough in children were mainly used for warming， tonifying， dissipating cold， excreting water， alleviating edema， and astringing lung and intestines， while in modern medication， the prescriptions were mainly for dispersing wind， clearing heat， tonifying yin， and moistening dampness.

Conclusion
