doi: 10.12032/ATR20200603 ARTICLE Abstract Background: To explore active components of Lanbuzheng (Gei herba) and its underlying complex mechanism in treating blood deficiency induced by chemotherapy drug based on network pharmacology and mice experimental validation. Methods: Active components of Lanbuzheng (Gei herba) were screened by Lipinski’s rule of five. Targets acted with active components were predicted by PharmMapper database, and targets whose function associated with blood deficiency were screened by Therapeutic Target Database and UniProt. The networks of component-target and target-pathway were constructed by Cytoscape. The levels of peripheral blood and organ indexes were detected in the animal experiments. Results: One hundred and seventy-three components of Lanbuzheng (Gei herba) were collected, and 60 active components were screened according to the rule of five. According to the degree value of compounds, the top 5 compounds were docosyl trans ferulate, C32 decursin, agrimonolide 6-O-β-D-glucoside, degree = 11, 173-ethoxyphaeophorbide, and eugenol. Finally, 59 targets associated with blood deficiency were obtained and the top 5 targets were MAPK14, TTR, CDK2, AKR1B1 and AR. Based on the interaction network of component- target and target-pathway, it’s found that 60 active components could act with 59 targets and 44 pathways for treating blood deficiency. And then, the mice experiments showed that Lanbuzheng (Gei herba) could enrich blood by increasing the levels of red blood cell, white blood cell, hemoglobin, red blood cell specific volume and platelet, and the indexes of liver, thymus and spleen, which validated the treating effect of Lanbuzheng (Gei herba). Conclusion: In this study, a network pharmacology approach and animal experiments were established to explore the nourishing blood effect of Lanbuzheng (Gei herba). The results demonstrated that Lanbuzheng (Gei herba) could improve blood deficiency and provide a theoretical basis for the further research on the in-depth mechanism of Lanbuzheng (Gei herba).

Now, network pharmacology has been symptom of traditional Chinese medicine (TCM) [1], applied to study of the mechanism of many blood- was a pathological state induced by insufficient blood supplemented TCMs, such as the Chinese patent production or decreased blood support function. And the medicine Xinshenghua granule which consisted of pathological features are similar to modern Danggui (Angelicae sinensis radix), Yimucao (Leonuri hematopoietic impairment diseases [2], such as herba), Chuanxiong (Chuanxiong rhizoma), Taoren malnutrition anemia, anemia induced by tumor (Persicae semen), Ganjiangtan (Zingiberis rhizome chemotherapy, low immunity and so on. Modern carbonisata), Zhigancao (Glycyrrhizae radix et rhizome pharmacology showed that iron, recombinant praeparata cum melle) and Honghua (Carthami flos) at granulocyte-colony stimulating factor and a proportion of 80: 90: 30: 8: 5: 5: 5 [17], the classic erythropoietin were presently common medicines for ancient prescription Danggui buxue decoction which the treatment of hematopoietic impairment diseases in consisted of Danggui (Angelicae sinensis radix) and clinic [3]. However, these medicine treatments showed Huangqi (Astragali radix) at a ratio of 1:5 [20–21] and certain side effect, high cost and individuality [4–5]. Danggui (Angelicae sinensis radix)-Honghua Nowadays, TCM has attracted more and more attention (Carthami flos) herb pair [22]. Therefore, network from researchers for the treatment of BD due to fewer pharmacology is a new preferred approach to predict the toxic side effects, lower price and more safety. Based on mechanism of TCM. TCM theory, enriching blood and Qi (it is the most basic In this study, network pharmacology was employed element that constitutes human body and maintains life to predict the blood enriching effect of GH, then the activities in TCM) are the main methods to treat BD, related mechanism was explored, finally, animal and TCM treatment of BD has achieved good results experiments were performed to validation. both in clinical and animal experiments. For example, Danggui (Angelicae sinensis radix) and the classic Material and methods ancient prescription Danggui Buxue decoction which consisted of Danggui (Angelicae sinensis radix) and Active compounds of GH screening Huangqi (Astragali radix) at a ratio of 1:5 have been Chinese Pharmacopoeia 2015 version, Wanfang shown a good replenishing effect [6–7]. database (http://www.wanfangdata.com.cn/), Chinese Lanbuzheng (Gei herba, GH) is the dried whole grass National Knowledge Infrastructure database of Geum aleppicum Jacq. and Geum japonicum Thunb.
