Exploring Modern Mechanism of Treating Diabetic Retinopathy and Coronary Heart Disease from Perspective of Blood Stasis Under Viewpoint of Treating Different Diseases with the Same Method / 中国实验方剂学杂志

Diabetic retinopathy（DR） and coronary heart disease（CHD） are both major chronic vascular complications that seriously jeopardize the health of the population and often occur together in clinical practice， it is of great clinical value to actively explore the association between the two in the process of disease development and methods of prevention and treatment of modern medicine and traditional Chinese medicine（TCM）. According to TCM， the heart and eyes physiologically communicate with each other by taking Qi， blood and veins as bridges， blood stasis obstructing collaterals is the common TCM etiology of DR and CHD， whose mechanism involves inflammation， oxidative stress and endothelial dysfunction. Promoting blood circulation and removing blood stasis plays an important role in the same treatment for different diseases and prevention and treatment of comorbidities， possibly by inhibiting the expression of interleukin-1β（IL-1β）， endothelin-1（ET-1） and hypoxia inducible factor-1α/vascular endothelial growth factor（HIF-1α/VEGF）， regulating phosphatidylinositol 3-kinases/protein kinase B/mammalian target of rapamycin（PI3K/Akt/mTOR） pathway， initiating adenosine monophosphate（AMP）-activated protein kinase/silent information regulator 1（AMPK/SIRT1） and nuclear transcription factor erythroid 2-related factor 2/heme oxygenase-1（Nrf2/HO-1） signaling pathways， inhibiting Hippo/Yes-associated protein（Hippo/YAP） signaling pathway， inhibiting mitochondrial permeability transition pore and anti-platelet agglutination for treating DR and CHD， which provides a multi-component， multi-pathway and multi-target selection strategies and ideas for the prevention and treatment of DR and CHD by TCM from a biological perspective. Based on this， subsequent studies should focus on constructing clinically relevant comorbidity models， conducting multicenter prospective studies， and fully utilizing artificial intelligence technology to gain a deeper understanding of the relationship between the two diseases， so as to elucidate the mechanism of promoting blood circulation and removing blood stasis in preventing and treating panvascular diseases.

ObjectiveTo explore the differences in the protective effects of five formulas for promoting blood circulation and removing blood stasis on the aortic endothelial cells of New Zealand rabbits with heart blood stasis syndrome. MethodEighty New Zealand rabbits were randomly divided into a normal group （n=10） and an experimental group （n=70）. The heart blood stasis syndrome model was induced by starvation combined with a high-fat diet and adrenaline in the rabbits of the experimental group. Subsequently， the model rabbits were randomly divided into a model group， a Xuefu Zhuyutang group （3.55 g·kg-1·d-1）， a Taohong Siwutang group （2.66 g·kg-1·d-1）， a Danshenyin group （1.962 g·kg-1·d-1）， a Huoluo Xiaolingdan group （2.80 g·kg-1·d-1）， a Shixiaosan group （0.56 g·kg-1·d-1）， and a c-Jun N-terminal kinase （JNK） inhibitor （SP600125， 5 μg·kg-1）group. The normal group and the model group received the same amount of distilled water. The rabbits in five Chinese medicine groups were treated correspondingly by gavage， and those in the SP600125 group were injected with 0.5 mL of SP600125-dimethyl sulfoxide diluent. After the treatment， the aorta was collected， and terminal deoxynucleotidyl transferase dUTP nick end labeling （TUNEL） assay was used to detect the apoptosis of aortic endothelial cells. The enzyme-linked immunosorbent assay （ELISA） was used to detect serum levels of tumor necrosis factor-α （TNF-α） and interleukin-6 （IL-6）. Western blot was used to detect the protein expression of JNK， phosphorylated JNK （p-JNK）， B-cell lymphoma-2 （Bcl-2）， Bcl-2-associated X protein （Bax）， cysteinyl aspartate-specific protease-9 （Caspase-9）， and cysteinyl aspartate-specific protease-3 （Caspase-3） in aortic tissues. Real-time fluorescence-based quantitative polymerase chain reaction （Real-time PCR） was used to detect the mRNA levels of JNK， Bcl-2， Bax， Caspase-9， and Caspase-3 in aortic tissues. ResultFive formulas could improve the apoptosis of aortic endothelial cells to varying degrees. To be specific， Xuefu Zhuyutang and Taohong Siwutang were optimal in efficacy， followed by Huoluo Xiaolingdan， Shixiaosan， and Danshenyin， and SP600125 was the worst （P<0.05， P<0.01）. Five formulas could reduce the content of TNF-α and IL-6 （P<0.05， P<0.01）， down-regulate the protein expression levels of JNK， p-JNK， Bax， Caspase-9， and Caspase-3 （P<0.05， P<0.01）， decrease the mRNA expression levels of JNK， Bax， Caspase-9， and Caspase-3 （P<0.05， P<0.01）， and up-regulate the protein and mRNA expression levels of Bcl-2 （P<0.05， P<0.01）. ConclusionFive formulas can all reduce the apoptosis of aortic endothelial cells in New Zealand rabbits with heart blood stasis syndrome with different efficacies. It may be related to the different effects of five formulas on the JNK signaling pathway.

Study on efficacy markers of Salviae Miltiorrhizae Radix et Rhizoma for promoting blood circulation and remving blood stasis based on systematic traditional Chinese medicine / 中国中药杂志

Traditional Chinese medicine for promoting blood circulation and removing blood stasis has been widely used in clinical practice. However, due to the diversity of the composition of traditional Chinese medicine and the complexity of its interaction with human body, it is difficult to apply traditional quality control ingredients to characterize its overall efficacy. Systematic traditional Chinese medicine is an effective method for studying the efficacy of traditional Chinese medicine, embodying the dialectical unity of holism and reductionism. Salviae Miltiorrhizae Radix et Rhizoma is a common traditional Chinese medicine for promoting blood circulation and removing blood stasis. In this study, we constructed a multi-dimensional network of "efficacy-pharmacological efficacy-targets-components" based on systematic traditional Chinese medicine, and discussed the discovery of the efficacy markers of Salviae Miltiorrhizae Radix et Rhizoma for promoting blood circulation and removing blood stasis. Firstly, based on the Chinese medicine efficacy-pharmacology database, the most relevant pharmacological actions(boundary) for promoting blood circulation and removing blood stasis(function) were obtained, and the target sets(structure) of the corresponding pharmacological action were obtained by the DrugBank database. Then, STRING database was used to construct protein-protein interaction network(relationship) of targets related to promoting blood circulation and removing stasis, and key targets(elements) in the network were selected by evaluating topological parameters of targets. Finally, the potential efficacy markers of Salviae Miltiorrhizae Radix et Rhizoma were predicted by molecular docking based on the key targets of promoting blood circulation and removing blood stasis. The results demonstrated that salvianolic acid B, salvianolic acid A, tanshinone Ⅱ_A and tanshinone Ⅰ were the potential markers of Salviae Miltiorrhizae Radix et Rhizoma on promoting blood circulation and removing blood stasis. Salvianolic acid B, salvianolic acid A, tanshinone Ⅱ_A had been reported to have anti-platelet aggregation, anti-thrombotic, cardiovascular protection and some other pharmacological functions. Based on systematic traditional Chinese medicine, we have preliminarily predicted the efficacy markers of Salviae Miltiorrhizae Radix et Rhizoma in promoting blood circulation and removing blood stasis in this study, providing a research method for the discovery of efficacy markers and a reference for the overall quality control of traditional Chinese medicine.

Research Progress of Different Components of Traditional Chinese Medicine in Treatment of Blood Stasis Syndrome / 中国实验方剂学杂志

To a certain extent, put forward the concept of " component of traditional Chinese medicine (TCM)" simplifies the complexity of multi-component and multi-target of TCM, which provides a possibility for the clarification of the material basis of the efficacy of TCM, and also provides a new direction for promoting the modernization and industrialization of TCM, promots the high quality development of TCM. The correlation between prescription and disease syndrome has made rapid progress, both basic research and clinical application are fruitful. However, the correlation between components and disease syndrome still needs to be further studied. The syndrome of blood stasis is a common syndrome of TCM science, and it is more common in various diseases, especially cardiovascular and cerebrovascular diseases, kidney disease, diabetes and hyperlipoidemia. A large number of studies have shown that some specific components contained in TCM or TCM compound can improve the related indexes of patients or experimental animal model with blood stasis syndrome. It is manifested in reducing blood viscosity, inhibiting platelet activation and adhesion aggregation, changing erythrocyte deformability index, inhibiting thrombosis and so on. Blood stasis is not only the pathogenic factor of many diseases, but also the pathological product of many kinds of diseases, which involves a wide range of diseases. Therefore, this study will study the progress of different components of TCM in the prevention and treatment of blood stasis syndrome, focusing on saponins, flavonoids, organic acids, polysaccharides, alkaloids and other active components in improving hemorheological abnormalities, hypercoagulability, platelet activation and adhesion aggregation, thrombosis. Based on the thought of component-disease syndrome, this paper searches the relevant literature in recent 20 years, classifies and summarizes the achievements of different components in the prevention and treatment of blood stasis syndrome, and hopes to provide some ideas for the further study of the pharmacological action of TCM components, the study of compatibility of TCM components and the research of TCM components.

Measurement of antiplatelet aggregation and potency of hirudo / 药学学报

The objective of this work was to develop a bioassay to quantify the antiplatelet aggregation activity of hirudo for quality evaluation and control. Antithrombin activity of hirudo extracted by high temperature decoction was determined by thrombin titration. Antiplatelet aggregation activity of hirudo was determined through pharmacodynamic experiments in vitro and in vivo using a bioassay we developed for quantifying inhibition of platelet aggregation. Methodological investigation was carried out and the titers of 12 batches of hirudo samples were determined. During the experiment, the disposal of animals is in accordance with the ethical standards of animal experiments. The results showed that the antithrombin activity of hirudo decocted at high temperature decreased significantly and almost lost its activity. Hirudo inhibited platelet aggregation and results in vivo and in vitro were consistent. These assays were employed to test 12 batches of hirudo. The results demonstrated that the biopotency of 12 batches was 113.49, 96.13, 121.22, 127.33, 83.48, 108.72, 131.41, 127.95, 76.90, 126.27, 132.89 and 573.53 U·mg-1. The method was reliable and reproducible and can be used to assess the quality of hirudo.

Exploring molecular mechanisms of anti-platelet adhesion of Chinese medicine for promoting blood circulation and removing blood stasis by activity screen and network analysis / 药学学报

Platelet adhesion is a key process in thrombosis. Anti-platelet adhesion effect of some Chinese medicines for promoting blood circulation and removing blood stasis (PBCRBS) has been reported, but their relative efficacies as a whole and specific targets remained unclear. This paper combined activity screening, drug compatibility analysis, pathway clustering, target prediction, and molecular docking to explore the mechanism of anti-platelet adhesion by PBCRBS Chinese medicine. Screening the activity of anti-platelet adhesion of 58 commercially available PBCRBS Chinese patent medicines showed that about 50.0% significantly inhibit ADP-induced platelet adhesion in vitro, and about 96.6% significantly inhibit thrombin-induced platelet adhesion in vitro. The animal experiment involved was approved by the Animal Ethics Committee of Tianjin International Biomedical Research Institute. Combined with the auxiliary platform for TCM (V2.0) inheritance showed that the compatibility of Danshen-Chuanxiong was used most frequently among the top 20 active proprietary Chinese patent medicines. IPA network analysis revealed that IL-1, APP and CCL2 might be the key targets for anti-platelet adhesion function of Danshen-Chuanxiong against atherosclerosis, neuroinflammation and chemokine signaling pathways as the main mechanisms. Molecular docking analysis confirmed the interaction between one of the active compounds shared by Danshen and Chuanxiong, i.e. chlorogenic acid, with its target CCL2. This study provides TCM theory guidance and experimental support for targeting platelet adhesion in anti-thrombosis therapy by Chinese medicine for promoting blood circulation and removing blood stasis.

Nature-effect relationship research of cold and warm medicinal properties of traditional Chinese medicine for promoting blood circulation and removing blood stasis based on nature combination / 中国中药杂志

Traditional Chinese medicine for promoting blood circulation and removing blood stasis is a kind of drug with cold or warm medicinal properties which is commonly used in clinical practice. It is an excellent carrier for studying the nature-effect relationship of traditional Chinese medicine. Therefore,this study will acquire the main active components and targets based on the drug-based research method. The Cytoscape 3. 5. 1 platform was used to construct the protein interaction network,and the Bin GO plug-in was used to perform functional annotation and statistical analysis on the identified functional modules. The results showed that the bitter-liver protein interaction network mainly participates in cell cycle process,lipid catabolic process,blood circulation to exert the effect of promoting blood circulation and removing blood stasis; the cold protein interaction network mainly participates in vasoconstriction through targets such as EDNRA,regulates blood coagulation through targets such as PLAU,and thus exerts the effect of cooling blood and eliminating phlegm; warm protein interaction network mainly participates in the regulation of platelet activation through targets such as P2 RY12,thereby exerting the effect of promoting blood circulation,relieving pain and relieving pain. This study explains the common characteristics of the bitter-liver combination and the specific characteristics of cold or warm medicinal properties from the molecular network level,which provides a new idea for the intrinsic relationship between the medicinal properties and efficacy of traditional Chinese medicine.
