To clarify the key quality attributes of substance benchmarks in Danggui Buxue Decoction(DBD), this study prepared 21 batches of DBD substance benchmarks, and established two methods for detecting their fingerprints, followed by the identification of peak attribution and similarity range as well as the determination of extract and transfer rate ranges and contents of index components ferulic acid, calycosin-7-O-β-D-glucoside, and astragaloside Ⅳ. The mass fractions and transfer rates of DBD substance benchmarks from different batches were calculated as follows: ferulic acid(index component in Angelicae Sinensis Radix): 0.037%-0.084% and 31.41%-98.88%; astragaloside Ⅳ(index component in Astragali Radix): 0.021%-0.059% and 32.18%-118.57%; calycosin-7-O-β-D-glucoside: 0.002%-0.023% and 11.51%-45.65%, with the extract rate being 18.4%-36.1%. The similarity of fingerprints among 21 batches of DBD substance benchmarks was all higher than 0.9. The quality control method for DBD substance benchmarks was preliminarily established based on the HPLC fingerprint analysis and index component determination, which has provided a basis for the subsequent development of DBD and the quality control of novel related preparations.

Colon cancer-related anemia (CCRA) is mainly caused by systemic inflammation, intestinal bleeding, iron deficiency and chemotherapy-induced myelosuppression in colon cancer. However, the best therapeutic schedule and related mechanism on CCRA were still uncertain. Studies on blood enrichment and anti-tumor effects of combined Danggui Buxue Decoction (DBD), Fe and rhEPO based on CCRA and gut microbiota modulation were conducted in this paper. Here, CCRA model was successfully induced by subcutaneous inoculation of CT-26 and i.p. oxaliplatin, rhEPO + DBD high dosage + Fe (EDF) and rhEPO + DBD high dosage (ED) groups had the best blood enrichment effect. Attractively, EDF group also showed antitumor activity. The sequencing results of gut microbiota showed that compared to P group, the relative abundances of Lachnospiraceae and opportunistic pathogen (Odoribacter) in ED and EDF groups were decreased. Interestingly, EDF also decreased the relative abundances of cancer-related bacteria (Helicobacter, Lactococcus, Alloprevotella) and imbalance-inducing bacteria (Escherichia-Shigella and Parabacteroides) and increased the relative abundances of butyrate-producing bacteria (Ruminococcaceae_UCG-014), however, ED showed the opposite effects to EDF, this might be the reason of the smaller tumor volume in EDF group. Our findings proposed the best treatment combination of DBD, rhEPO and Fe in CCRA and provided theoretical basis and literature reference for CCRA-induced intestinal flora disorder and the regulatory mechanism of EDF.

ABSTRACT
Diabetes mellitus (DM) is a chronic metabolic disease characterized by hyperglycemia. Its main complications of diabetes, such as diabetic angiopathy, have seriously affected the quality of life for patients, and have become an important cause of death and disability. The underlying pathological changes include macrovascular lesions and microvascular lesions. Diabetic macrovascular lesions mainly involve thoracic aorta, coronary artery, carotid artery, cerebral artery and peripheral blood vessels, etc., and the common clinical diseases include coronary heart disease, stroke, peripheral neuropathy, lower extremity arteriosclerosis, etc. Diabetic microvascular lesions mainly involve the heart, brain, kidney and other microvessels. Nowadays, various new oral hypoglycemic agents and insulin have emerged in the society and are widely used in clinical practice. However, traditional Chinese medicines(TCMs) have stable curative effect, less side effect, and can improve glucose metabolism, lipid metabolism, insulin resistance, oxidative stress, expression of inflammatory cytokines, vascular endothelial injury, microcirculation disorders, balance of fibrinolysis system and blood coagulation system, and improve the syndromes of TCMs, etc. They have been widely recognized and applied in the prevention and treatment of diabetic angiopathy. A profound understanding on the etiology, pathogenesis and treatment of diabetic angiopathy has been formed in Chinese medicine. Therefore, in this paper, we would summarizes the understanding on Chinese medicine for diabetic angiopathy and the mechanism of Yiqi Huoxue prescription in the treatment of diabetic angiopathy in the past three years.
ABSTRACT
Objective: Taking Danggui Buxue Decoction (DBD) as the research object, the differences of chemical composition types and content among traditional decoction, self-made granule decoction and marketable granule decoction were compared, in order to provide scientific basis for clinical application of Chinese medicine formul granules. Methods: The fingerprint was established by HPLC. The value of the chemical composition, the content of the index components, the area of the common peak area, and the similarity of the fingerprint were evaluated, and the different dosage forms of the decoction of DBD were investigated. The effect of chemical composition on the chemical equivalence of traditional decoction and formula granules was compared. Results: The number of chromatographic peaks ranged from 15 peaks of traditional decoction to 13 (factory A), 12 (self-made), 11 (factory B), and 9 (factory C). The content of ferulic acid in formula granules was significantly different from that in traditional decoction (P formula granule decoction of factory A > self-made formula granule decoction > formula granule decoction of factory B > formula granule decoction of factory C. Content of campanulin was in order : self-made formula granule decoction > traditional decoction > formula granule decoction of factory A > formula granule decoction of factory B > formula granule decoction of factory C. The total peak area of formula granule decoction was lower than that of traditional decoction. If the traditional decoction was 1, the others (self-made and factories A, B, C) were equivalent to 0.95, 0.66, 0.40 and 0.47, respectively. Comparing with traditional decoction, self-made formula granule decoction and formula granules from factories A and B had higher similarity (0.97, 0.96, 0.98), while that from factory C was slightly lower (0.85). The main chromatographic peaks of DBD were found to be from the single herbs and no new chemical components were found. The disappearance of ingredients in formula granule Decoction was found. Conclusion: The content of index components and the number of chromatographic peaks of traditional decoction of DBD is higher than those in the formula granule decoction. There are some differences between them. This indicates that the clinical equivalence of formula granules is not consistent with the reality of decoction, so the recommended clinical equivalence of formula granules of traditional Chinese medicine should be corrected to promote rational clinical application, which can provide scientific research ideas for the unified management of the quality of formula granules of Chinese materia medica.

ABSTRACT
The "black" of Chinese materia medica (CMM) has been criticized all the time. The Maillard reaction exists widely in the course of food processing, which affects the product's color and odor. The suitable conditions of Maillard reaction also exist in the processing of CMM preparation. The Maillard reaction has significant impact to the study of CMM's material basis. So the Maillard reaction and its products in the processing of CMM preparation should be studied. Taking the Danggui Buxue Decoction for instance, the chemical composition of the prescription was consulted by the TCMSP of Northwest A&F University, and then the constituents were classified, the possibility of the Maillard reaction occured in the processing of CMM preparation was analyzed. New ideas on study of material basis of CMM will be put forward.
