The incompatibility of traditional Chinese medicines is related to the clinical medication safety, so has attracted wide attentions from the public. With the deepening of studies on the incompatibility of traditional Chinese medicines represented by 18 incompatible herbs, the incompatibility of theory traditional Chinese medicines has raised to new heights. From the origin of incompatibility theory of traditional Chinese medicines, relationship of herbs, harms of incompatible herbs and principle of prevention to toxic effects of specific incompatible medicines, the innovation and development of the traditional Chinese medicine incompatibility theory was explored. Structurally, the incompatibility of traditional Chinese medicines refers to the opposition of two herbs based on seven emotions and clinical experience. The combination of incompatible herbs may lead to human harms, especially latent harm and inefficacy of intervention medicines. The avoidance of the combination of incompatible herbs and the consideration of both symptoms and drug efficacy are the basic method to prevent adverse reactions. The recent studies have revealed five characteristics of incompatible herbs. Toxicity potentiation, toxication, efficacy reduction and inefficacy are the four manifestations of the incompatible relations. The material changes can reflect the effects of toxicity potentiation and toxication of opposite herbs. The accumulation of toxicity and metabolic changes are the basis for latent harms. The antagonistic effect of main efficacies and the coexistence of positive and negative effects are the distinctive part of the incompatibility. The connotation of incompatible herbs plays an important role in the innovation of the traditional Chinese medicine incompatibility theory.

The combination of Danggui and Honghua (GH) is a popular herb pair commonly used in clinic for the treatment of blood stasis syndrome in China. To evaluate the activating blood circulation and dissipating blood stasis effects of the combination of different proportions of Danggui and Honghua on acute blood stasis rats, and optimize the proportion of GH to have the best activating blood circulation and dissipating blood stasis effect. Acute blood stasis rat model was induced by subcutaneous injection of adrenaline and ice water bath. The blood stasis rats were administrated intragastrically with GH (1 : 0, 4 : 1, 2 : 1, 3 : 2, 1 : 1, 2 : 3, 1: 2, 1 : 4 and 0 : 1) extracts. The whole blood viscosity (WBV), plasma viscosity (PV), and high shear whole blood relative index (HSWBRI), low shear whole blood relative index (LSWBRI), and erythrocyte aggregation index (EAI) were tested to observe the effects of GH on hemorheology of blood stasis rats. And the maximum aggregation induced by adenosine diphosphate (ADP) was tested to observe the effect of GH on platelet aggregation index of blood stasis rats. In addition, the prothrombin time (PT), thrombin time (TT), activated partial thromboplastin time (APTT) and plasma fibrinogen (FIB) were tested to observe the effects of GH on blood coagulation function of blood stasis rats. Then principal component analysis and multi-attribute comprehensive index methods were both used to comprehensively evaluate the total activating blood circulation and dissipating blood stasis effects of GH. The results showed that the hemorheological indexes and coagulation parameters of model group both had significant differences with normal group. Compared with model group, GH (1 : 0, 4 : 1, 2: 1, 3 : 2, 1 : 1, 2 : 3, 1 : 2, 1 : 4 and 0 : 1) could improve all the blood hemorheology indexes and regulate part indexes of blood coagulation function and platelet aggregation in acute blood stasis rats. Based on principal component analysis and multi-attribute comprehensive index methods, GH 1 : 1 and GH 3 : 2 both had the best effect of blood circulation and dissipating blood stasis, and the effect of GH 1 : 1 was slightly better than GH 3 : 2. These results suggest that GH could obviously ameliorate the abnormality of hemorheology and blood coagulation function in acute blood stasis rats. The optimized proportion of GH was consistent with regulations of medicine usage that GH 1 : 1 had the highest frequency used in traditional Chinese formulae. It could provide scientific basis for more effective application of the compatibility between Danggui and Honghua in modern clinic medicine.

The metabolic effect of Fo-Shou-San on blood deficiency mice was studied by using metabolomic method. UPLC-QTOF/MS was used to analyze the plasma metabolome in blood deficiency mice. MS data were processed by MarkerLynx software. With multivariate statistical analysis of plasma metabolite profiles, a clear separation among control, blood deficiency model, and Fo-Shou-San groups was achieved. Potential biomarkers were selected according to the parameters of variable importance in the projection (VIP) and identified according to MS information and database retrieval. The metabolic network of blood deficiency was predicted via MetPA database. Twenty-two potential biomarkers were identified and used to explain the thiamine metabolism, arachidonic acid metabolism, sphingolipid metabolism, glyoxylate and dicarboxylate metabolism, histidine metabolism, nicotinate and nicotinamide metabolism, cysteine and methionine metabolism, tryptophan metabolism, starch and sucrose metabolism, tyrosine metabolism and citrate cycle (TCA cycle). Those metabolic pathways were disturbed in blood deficiency mice, but which could be regulated nearly to normal state after Fo-Shou-San administration. In this study, the metabolomics of blood deficiency mice and the action mechanism of nourishing blood effect of Fo-Shou-San were evaluated. The physiological and metabolic state of the organism could be represented comprehensively by using metabolomics. And metabolomics can be used to evaluate the pharmacodynamics and related mechanisms of Chinese medicine and formulae.

The combination of Angelicae sinensis Radix (Danggui, DG) and Astragali Radix (Huangqi, HQ) is a popular herb pair commonly used in clinic for the treatment of blood deficiency syndrome in China. The aim of this paper is to study the interaction of DG and HQ nourishing and tonifying blood effects by response surface method. The blood deficiency mice were induced by injecting N-acetylphenylhydrazine (sc) and cyclophosphamide (ip). The blood deficiency mice were administrated intragastrically with DG-HQ extracts (0:1, 1: 5, 2:5, 2:3, 1:1, 3:2, 5:2, 5:1, 1:0). The changes of the peripheral blood indexes and organ indexes were observed. The indexes were integrated by comprehensive index method; the interactions of DG and HQ were analyzed by the response surface diagram established with Matlab software. The results showed that DG and HQ at most of their combination ratios had synergic effect. Within the range of 1:5 - 5:1, all of the extracts of DG-HQ showed synergic effect, and among which, high-doses had better effects than low-doses. The highest value (-1) of the synergic effect was showed when DG was 10 - 40 g at the same time of HQ as 90 -180 g, and DG was 50 - 100 g at the same time of HQ as 20 - 100 g. DG-HQ at all combination dosages within Chinese Pharmacopeia (DG: 6 - 12 g, HQ: 9 - 30 g) had certain synergic effect, and Danggui Buxue Decoction (DG: 6 g, HQ: 30 g) also was at this range. The results provided scientific basis to the clinical application of DG and HQ. And the response surface method was firstly applied to quantitatively evaluate the bio-activity change of herb combination, which provided a novel way for modern basic research on the interaction of herbs.

OBJECTIVETo study the pharmacodynamic interaction of nourishing and tonifying blood effects of the herb pair consisting of Angelica sinensis and Ligusticum chuanxiong by response surface method.
METHODSThe blood deficiency rat model was induced by injecting N-acetylphenylhydrazine and cyclophosphamide. The effects of Angelica sinensis and Ligusticum chuanxiong in different proportions (0:1, 1:5, 2:5, 2:3, 1:1, 3:2, 5:2, 5:1, and 1:0) and at different concentrations on the peripheral blood index and the organ indices were observed. Then all indices were integrated to the total nourishing effect value by comprehensive index method. The interaction was analyzed by response surface method. The model parameters were estimated with nonlinear regression. The three-dimensional response surfaces were constructed with Matlab Software.
RESULTSIn the response surface, most compatibility of Angelica sinensis and Ligusticum chuanxiong showed synergistic action, some showed addition action, and few of them showed obvious antagonist action. The proportion of Angelica sinensis and Ligusticum chuanxiong from 4:1 to 2:1 and the dose of Angelica sinensis and Ligusticum chuanxiong from low to high showed addition action, while the other proportions showed obvious addition action at low dose and synergistic action at high dose.
CONCLUSIONSThe research results could provide scientific evidence for reasonable application of Angelica sinensis and Ligusticum chuanxiong in clinics of Chinese medicine. The quantitative analysis on drug interactions of herbal compatibility by response surface method could provide reference for relative studies.

OBJECTIVETo observe the in vitro antioxidant interaction of different preparations and proportions of Danggui-Chuanxiong drug pair in the DPPH free radical scavenging rate with the response surface methodology.
METHODThe 2,2-diphenyl-1-picryl-hydrazyl (DPPH) free radical scavenging rate method was adopted for determining the antioxidant activity of extracts from Danggui-Chuanxiong with 10 proportions and three extraction processes. The response surface methodology was used to determine the parameters of the dose-effect curve and establish a three-dimensional response surface model. The three-dimensional response surface graph was constructed with Matlab software.
RESULTAll of the 30 samples with different proportions and preparations had antioxidant effect in scavenging free radicals and a remarkable dose-effect relationship. Their water extracts had a narrow synergistic range, with only spot distribution. Their antagonist ranges were districted in six bands of various widths. The synergistic ranges of ethanol extracts were districted in small bands, with the antagonist ranges scattered in points. The synergistic ranges of their water-alcohol extracts were distributed in three bands, with their antagonist ranges scattered in points. In short, the water-alcohol extracts showed a wider synergistic range than ethanol extracts, followed by water-extracts. All of the three extraction processes showed no obvious synergistic and antagonist effects.
CONCLUSIONThe quantitative study on the interaction of traditional Chinese medicines with different compatibilities with the response surface methodology provides reference of thoughts and methods for relevant studies.

By investigating the interaction between components from Flos Genkwa (FG) and Radix et Rhizoma Glycyrrhizae (RRG) and the dissolution profile of toxic components in co-decoction, the characteristics and possible mechanism of incompatibility were revealed. Ultra-high performance liquid chromatography quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS) and ultra-high performance liquid chromatography triple-quadrupole mass spectrometry (UPLC-TQ/MS) were used to analyze multi-components in different herb extractions prepared by different ratios of FG/FG processed by vinegar (FGV) and RRG, which reflect the interaction and characteristics of multiple components in incompatibility combinations. The results showed that the components dissolution was influenced by compatibility ratio with certain regularity. Whether FG processed by vinegar or not, with the increase of RRG in co-decoction, the dissolution of diterpenes, especially for yuanhuacine, yuanhuadine and yuanhuajine, the toxic ingredients of FG, increased significantly. From these results, the material basis and one possible mechanism of incompatibility between FG and RRG is the increasing dissolution of diterpenes, toxic components of FG in co-decoction process, which caused by interaction between multi-components in these two herbs.
