[Complex network analysis of law on Chinese herbal drugs intervention on radiation induced lung injury].

To mainly analyze the prescription rules of Chinese herbal drugs for radiation induced lung injury, optimize the prescriptions, and provide a reference for the clinical treatment of radiation induced lung injury. The major Chinese databases CNKI, CBM and Wanfang data were searched to obtain the literature on Chinese herbal drugs for radiation induced lung injury. BICOMS 2 software was used to extract and collect all Chinese herbal drugs information and generate the co-occurrence matrix; NetDraw and Gcluto software were then used to make network map and visualization matrix for analysis. A total of 552 articles (19 types and 304 Chinese herbal drugs) were included. Ophiopogon japonicus had the highest frequency (229 times), followed by Astragalus membranaceus(181 times), Glycyrrhiza uralensis (166 times), and Scutellaria baicalensis (150 times). After the classification of efficacy, deficiency-supplementing medicinal (69 kinds of Chinese herbs), heat-clearing medicine (51 kinds of Chinese herbs) and phlegm cough medicine (42 kinds of Chinese herbs) accounted for 53.29% of all the Chinese herbs, acting in the main position. After the prescription analysis for the top 25 herbal prescriptions, six main structures of common prescriptions were found for the treatment of radiation induced lung injury. There are many kinds of Chinese herbal drugs for the treatment of radiation induced lung injury in clinical application. In the future, researchers can mainly focus on Ophiopogon japonicus etc. as the main drugs, combine with other high-frequency Chinese herbal drugs found in this study, or directly refer to the main structures of commonly used prescriptions found in this analysis.
