To carry out data mining on the prescriptions of traditional Chinese medicine （TCM） for the treatment of renal anemia， and to explore the medication rules of TCM in the treatment of renal anemia.

METHODS

2

The Chinese and English databases including PubMed， the Cochrane Library， Web of Science， CNKI， Wanfang， VIP and CBM were searched by computer to screen the related literature about TCM in the treatment of renal anemia. Excel software was used to extract prescription information， including frequency of use， property and flavor， meridian tropism and efficacy of single TCM. Association rule analysis and hierarchical clustering analysis were performed for each ingredient of TCM with R language.

RESULTS

2

A total of 268 literature were included， involving 169 ingredients with a total use frequency of 3 919 times. Among them，

Astragalus memeranaceus， Angelica sinensis， Atractylodes macrocephala， Rheum officinale， Poria cocos

， Radix Rehmanniae Praeparata， Radix Codonopsis，

Salvia miltiorrhiza

and

Ligusticum chuanxiong

were used more than 100 times. The properties and flavors of the drugs were mainly warm and sweet； meridian tropism mainly targeted spleen， liver and kidney； the function was mainly in replenishing qi， nourishing blood， promoting blood circulation and removing blood stasis， and clearing damp and promoting diuresis， purgation. The result of association rule analysis showed that the core ingredients were

A. memeranaceus， A. sinensis， A. macrocephala， P. cocos

and

S. miltiorrhiza

. Hierarchical cluster analysis showed that the clustering results were divided into grade 1， 2 and 3， and the cluster classification of

A. memeranaceus

and

A. sinensis

was always the same.

2

The core prescription for treating renal anemia includes
