Mechanism of Danshenyin in Inhibiting Platelet Activation in Rat Model of Hyperlipidemia Based on Proteomics / 中国实验方剂学杂志

ObjectiveTo decipher the mechanism of Danshenyin in regulating platelet activation in the rat model of hyperlipidemia by means of proteomics and molecular biology. MethodWistar rats were randomized into blank， model， and Danshenyin groups （n=10） according to the blood lipid level. The rats in the blank group were fed with a basic diet， and those in the model and Danshenyin groups with a high-fat diet. All the rats had free access to water and food. The treatment began at the 9th week. The rats in the Danshenyin group were administrated with Danshenyin by gavage at a crude drug dose of 3.6 g·kg-1. The rats in the model and blank groups were administrated with an equal volume of normal saline according to body weight. At the 12th week， the tissue samples were collected for the measurement of related indicators， and the blood lipid level was measured by an automatic biochemical analyzer. The whole blood viscosity and plasma viscosity were measured by an automatic hemorheometer. The platelet proteome was determined by liquid chromatography-mass spectrometry. Western blotting was employed to determine the protein levels of platelet membrane glycoprotein 4 （CD36）， focal adhesion kinase （FAK）， phosphatidylinositol 4-phosphate 5-kinase （PIP5K）， phosphorylated phosphatidylinositol 3-kinase （p-PI3K）， protein kinase B （Akt）， and phosphorylated protein kinase B （p-Akt）. ResultCompared with the model group， Danshenyin lowered the levels of total cholesterol （TC）， triglyceride （TG）， and low-density lipoprotein cholesterol （LDL-C） in the plasma （P<0.05）， elevated the level of high-density lipoprotein cholesterol （HDL-C） （P<0.05）， and reduced the platelet aggregation rate （P<0.05）. Compared with the blank group， the modeling up-regulated the expression of 44 proteins and down-regulated the expression of 12 proteins. Compared with the model group， Danshenyin up-regulated the expression of 21 proteins and down-regulated the expression of 22 proteins. Compared with the blank group， Danshenyin up-regulated the expression of 31 proteins and down-regulated the expression of 49 proteins. The gene ontology （GO） functional enrichment showed that the differentially expressed proteins were mainly involved in cholesterol transport and efflux， production of cytokines， dyslipidemia， and platelet activation. The Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment showed that the differentially expressed proteins were mainly involved in ECM-receptor interaction， peroxisome proliferators-activated receptors （PPAR）， focal adhesion， and PI3K/Akt signaling pathways. Danshenyin can significantly down-regulate the expression of CD36， FAK， PIP5K， PI3K， p-Akt （Ser473）， and p-Akt1/2/3 （Thr308）. ConclusionDanshenyin can restore the blood lipid level of hyperlipidemia rats and inhibit the platelet activation caused by abnormal lipid levels by down-regulating the CD36/PI3K/Akt signal cascade.

Pathogenesis and Traditional Chinese Medicine Prevention and Treatment Strategy of Refractory Angina Based on Theory of Stasis and Toxin / 中国实验方剂学杂志

Refractory angina is characterized by recurrent and persistent angina with a duration of not less than three months， which is related to reversible ischemia and hypoxia caused by coronary stenosis and obstruction. It mainly involves obstructive coronary artery disease and non-obstructive coronary artery disease with coronary artery spasm and coronary microvascular dysfunction. “Stasis and toxin” play an important role in the pathogenesis of cardiovascular diseases. The pathogenesis of stasis and toxin is stubborn filthy turbidity featured by slow accumulation and sudden onset，and rapid changes，which coincides with the characteristics of refractory angina which is complex and changeable，prolonged and difficult to cure. The pathogenesis of refractory angina involves a combination of underlying deficiency and excessive manifestation， with "stasis and toxin" playing a crucial role as an important pathological factor in the whole process of refractory angina. Traditional Chinese medicine （TCM） employs a holistic approach known as "activating blood circulation and removing toxins"， which is supplemented by various methods to tonify Qi and warm Yang， nourish the kidneys and invigorate the spleen， clear heat and transform phlegm. This approach applies anti-inflammatory measures， regulates lipid metabolism， inhibits oxidative stress and thrombus formation， protects endothelial function in blood vessels， as well as establishes collateral circulation for the prevention and treatment of refractory angina. Therefore，based on the theory of "stasis and toxin"，combined with TCM theory and modern medical research，this paper discusses the pathogenesis of refractory angina and the prevention and treatment strategy of TCM，and elucidates the reasons for the difficulty in curing refractory angina and the relationship between refractory angina and common angina pectoris，coronary microvascular dysfunction，coronary artery spasm and obstructive coronary artery disease，hoping to provide certain theoretical basis and clinical ideas for the prevention and treatment of refractory angina with TCM.

Mechanism of tonifying kidney and activating blood therapy for premature ovarian failure:a review / 中国中药杂志

Healthy birth and child development are the prerequisite for improving the overall quality of the population. However, premature ovarian failure(POF) threatens the reproductive health of women. The incidence of this disease has been on the rise, and it tends to occur in the young. The causes are complex, involving genetics, autoimmune, infectious and iatrogenic factors, but most of the causes remain unclear. At the moment, hormone replacement therapy and assisted reproductive technology are the main clinical approaches. According to traditional Chinese medicine(TCM), kidney deficiency and blood stasis are one of the major causes of POF, and TCM with the effects of tonifying kidney and activating blood has a definite effect. Through clinical trials, TCM prescriptions for POF have excellent therapeutic effect as a result of multi-target regulation and slight toxicity. In particular, they have no obvious side effects. A large number of studies have shown that the kidney-tonifying and blood-activating TCM can regulate the neuroendocrine function of hypothalamic-pituitary-ovarian axis, improve ovarian hemodynamics and microcirculation, reduce the apoptosis of granulosa cells, alleviate oxidative stress injury, and modulate immunologic balance. The mechanism is that it regulates the phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt), vascular endothelial growth factor(VEGF), transforming growth factor(TGF)-β/Smads, nuclear factor E2-related factor 2(Nrf2)/antioxidant response element(ARE), and nuclear factor-kappa B(NF-κB) signaling pathways. This article summarized the pathological mechanisms of tonifying kidney and activating blood TCM in the prevention and treatment of POF and explored the biological basis of its multi-pathway and multi-target characteristics in the treatment of this disease. As a result, this study is expected to serve as a reference for the treatment of POF with the tonifying kidney and activating blood therapy.

Pharmacological research progress of five classical prescriptions in treatment of chronic heart failure / 中国中药杂志

Chronic heart failure(CHF) is a comprehensive clinical syndrome caused by multiple factors that result in structural and/or functional abnormalities of the heart, leading to impaired ventricular contraction and/or relaxation functions. This medical condition represents the final stage of various cardiovascular diseases. In the treatment of CHF, multiple clinical studies have demonstrated the benefits of using traditional Chinese medicine(TCM) to control oxidative stress, inflammation, and apoptosis, thereby delaying ventricular remodeling and reducing myocardial fibrosis. In this study, common TCM syndromes in the diagnosis and treatment of CHF in recent years were reviewed and summarized. Five common treatment methods including benefiting Qi and activating blood circulation, enhancing Qi and nourishing Yin, warming Yang for diuresis, eliminating phlegm and dampness, rescuing from collapse by restoring Yang, and corresponding classic prescriptions in prevention and treatment of CHF were concluded under the guidance of TCM syndrome differentiation thinking. Meanwhile, research progress on the modern pharmacological effects of these classic prescriptions was systematically discussed, so as to establish a unique treatment system for CHF by classic prescriptions under the guidance of TCM syndrome differentiation theory and provide innovative diagnosis and treatment strategies for clinical CHF.

Salvia Miltiorrhiza Ligustrazine Injection + conventional western medicine had the best effect on reducing platelet aggregation rate in the blood. Shuxuening Injection + conventional western medicine had the best effect on reducing hs-CRP. However, more high-quality RCTs are needed for verification in the future to provide more reliable evidence-based medical reference.

Research progress on using traditional Chinese medicine and extracts for activating blood circulation in prevention and treatment of silicosis / 中国职业医学

Occupational silicosis features as irreversible pulmonary fibrosis, which is caused by long-term inhalation of free silica dust. The pathogenesis of silicosis is complex and there is no cure at present. Traditional Chinese medicine classifies silicosis fibrosis into the category of diseases as "pulmonary paralysis" and "pulmonary arthralgia", and its treatment is based on promoting blood circulation and activating qi. Traditional Chinese medicine for activating blood circulation is one of the commonly used medications, which has the effects of anti-oxidation, anti-inflammation, anti-fibrosis and immunomodulation, and has broad application prospect in the prevention and treatment of silicosis. At present, animal experiments and clinical studies have been carried out using the single Chinese herbs extracts that could activate blood circulation such as Salvia miltiorrhiza, Ligusticum chuanxiong Hort., Panax notoginseng, Curcuma longa L., peach kernel and Carthamus tinctorius L. as well as their compound herbs for the prevention and treatment of silicosis. The mechanisms of anti-pulmonary fibrosis and the efficacy and safety of treating silicosis and its complications were explored. There are also scholars studying Salvia miltiorrhiza, Curcuma longa L. and Danhong injection, Taohong Siwu Decoction and others for prevention and treatment of pulmonary fibrosis. Additionally, network pharmacological research, analyzing potential targets and pathways, were carried out to provide scientific rationale for prevention and treatment of silicosis. However, the effectiveness of research is still uncertain, and it cannot meet the clinical needs. In the future, it is necessary to explore the application of more high-quality active components of traditional Chinese medicine monomer or mixture of activating blood circulation in the prevention and treatment of silicosis, to provide new ideas and scientific basis for the prevention and treatment of silicosis using traditional Chinese medicine.

Effects of Tangtong formula on the expression of PI3K, Akt and mTOR in sciatic nerve of diabetic peripheral neuropathy rats / 国际中医中药杂志

Objective:To observe the effect of Tangtong formula on the expression of autophagy pathway proteins PI3K, Akt and mTOR in sciatic nerve of DPN rats, and to explore its mechanism. Methods:There were 60 male SD rats, 15 of which were randomly selected as the normal group, and the other rats were used to establish DPN model with STZ + ischemia-reperfusion method. Then they were divided into model group, Tangtong formula low-dose group and Tangtong formula high-dose group, with 15 rats in each group with random number table method. 36.67 g/kg Tangtong formula was administered by gavage in the high-dose group and 18.33 g/kg Tangtong formula was administered by gavage in the low-dose group, once a day. After 8 weeks of continuous gavage, the conduction velocity of sciatic nerve was detected. The mRNA and protein expression levels of PI3K, Akt and mTOR were detected by PCR and Western blot. The structure of sciatic nerve fibers was observed by HE staining. Results:Compared with the model group, the motor nerve conduction velocity, sensory nerve conduction velocity, muscle compound action potential and sensory nerve action potential in the low-dose Tangtong formula group and high-dose Tangtong formula group were increased ( P<0.05). The expression of PI3K mRNA(6.05±0.18, 3.36±0.29 vs. 11.57±1.93), Akt mRNA(1.26±0.13, 0.64±0.04 vs. 1.86±0.06), mTOR mRNA(1.82±0.11, 0.92±0.06 vs. 2.68±0.18) of sciatic nerve in rats of the low-dose and high-dose group were increased ( P<0.05). The expression of PI3K(0.40±0.00, 0.19±0.02 vs. 0.61±0.03), Akt(0.64±0.02, 0.45±0.01 vs. 0.83±0.02), mTOR(0.17±0.01, 0.09±0.00 vs. 0.34±0.01)of sciatic nerve in rats of the low-dose and high-dose group were increased ( P<0.05). The model group's nerve fibers were loose and swollen, myelin sheath became thin, and the axis Atresia, the neuromorphology of the low-dose and high-dose group tended to be normal, and the morphology of myelin sheath and axon were better. Conclusions:Tangtong formula could improve the conduction velocity and potential amplitude of sciatic nerve in DPN rats, reduce nerve injury and demyelinating changes, improve axon morphology and protect nerve fiber structure. Its mechanism might be related to activating PI3K/Akt/mTOR signal pathway and inhibiting excessive autophagy.

Role and Mechanism of Chinese Medicinal Materials and Their Compound Formulas with Effects of Replenishing Qi， Activating Blood， and Dispelling Stasis in Prevention and Treatment of Heart Failure / 中国实验方剂学杂志

Heart failure with high prevalence is the endpoint of many cardiovascular diseases. Once diagnosed， patients usually need lifelong medication， which seriously affects their quality of life. The drugs commonly used to treat heart failure include angiotensin-converting enzyme inhibitors， beta-blockers， aldosterone receptor antagonists， and diuretics. However， the long-term use of those drugs can lead to side effects such as hypotension， depletion of body fluid， and electrolyte imbalance and even increase mortality. According to the theory of traditional Chinese medicine （TCM）， Qi deficiency and blood stagnation is the major cause of heart failure and when Qi is not moving， blood is not flowing. Therefore， the TCM clinical treatment of heart failure uses the Chinese medicinal materials which replenish Qi， activate blood， and dispell stasis to treat both internal cause and external symptoms. Recent studies have demonstrated that Chinese herbal medicines such as Astragali Radix， Ginseng Radix et Rhizoma， Notoginseng Radix et Rhizoma， Salviae Miltiorrhizae Radix et Rhizoma， Angelicae Sinensis Radix， as well as the compound formulas such as Buyang Huanwutang， Simiao Yongantang， Qili Qiangxin capsules， and Qishen Yiqi drops， play a significant role in the prevention and treatment of heart failure via replenishing Qi， activating blood， and dispelling stasis. Inhibition of oxidative stress and inflammatory responses， mitigation of myocardial fibrosis， improvement of calcium cycling， and protection of mitochondrial function represent the key mechanisms for the treatment of heart failure with Chinese medicinal materials. Focusing on the pathogenic mechanisms and signaling pathways of heart failure， this paper systematically describes the pharmacological effects， molecular mechanisms， and research progress in the clinical application of Chinese medicinal herbs with effects of replenishing Qi， activating blood， and dispelling stasis and their compound formulas in the prevention and treatment of heart failure， aiming to provide scientific evidence for the development and clinical use of anti-heart failure Chinese medicinal materials.

Mechanism of Blood-activating and Toxin-removing Method in Treatment of Coronary Heart Disease and Cognitive Dysfunction Based on Treating Different Diseases with Same Method / 中国实验方剂学杂志

As China is about to enter an era of deep aging， the coexistence of multiple diseases is gradually increasing. Coronary heart disease （CHD） and cognitive dysfunction also show increasing incidence year by year. The two diseases affect and cause each other， becoming the major chronic diseases harmful to the health of the elderly. It is of great clinical significance to explore the methods integrating traditional Chinese and western medicine for the prevention and treatment of the two diseases. The relationship between CHD and cognitive dysfunction in traditional Chinese medicine （TCM） was first recorded in Huangdi’s Internal Classic （Huang Di Nei Jing）. As the understanding of CHD and cognitive dysfunction is deepening， the influences of stasis and toxin on both diseases have attracted increasing attention. According to the theories of TCM， CHD and cognitive dysfunction have common points in the etiology and pathogenesis. Therefore， the theory of treating different diseases with same method provides a theoretical basis for the clinical treatment of different diseases with the same pathogenesis. Moreover， this theory conforms to the principle of integrated and individualized prevention and treatment of multi-disease coexistence in modern medicine. This paper systematically proposed that the coexistence of stasis and toxin is a major pathogenesis of CHD and cognitive dysfunction. We then explored the possible mechanisms of the blood-activating and toxin-removing method in the treatment of CHD and cognitive dysfunction based on the theory of treating different diseases with same method. The mechanisms include the regulation of ceramide metabolism， activation of silent mating-type information regulation 2 homolog 1 （SIRT1）， inhibition of pyroptosis， regulation of mitogen-activated protein kinase/nuclear factor-κB （MAPK/NF-κB） signaling pathway， inhibition of mitochondrial division， and regulation of DNA methylation. We hope this paper will provide an idea for the future research on the prevention and treatment of CHD and cognitive dysfunction with TCM.

Mechanism of Therapeutic Methods of Activating Blood， Resolving Phlegm， and Removing Toxins in Liver Cancer Based on Immune Microenvironment / 中国实验方剂学杂志

Primary liver cancer is one of the common tumors in China， which seriously endangers human health. With the advancement in medical science and technology， some achievements have been made in the clinical treatment of liver cancer， but there is an urgent need to find a safe and effective solution for patients with advanced liver cancer. As a unique therapy in China， traditional Chinese medicine （TCM） has the characteristics of multiple targets and multiple pathways and plays a certain role in the treatment of malignancies. The present study aimed to clarify the mechanism of action of "dispelling pathogens" in the treatment of liver cancer through literature research. In TCM etiology and pathogenesis， deficient healthy Qi and exuberance of pathogenic Qi， such as phlegm， blood stasis， and toxins， lead to the development of liver cancer. The treatment should follow the principles of reinforcing healthy Qi and eliminating pathogens. It has been generally believed that tumor cell is the "pathogenic factor" and the immune function serves as the "healthy Qi". In the treatment of malignancies and the regulation of the immune function of patients， it is often advocated to reinforce healthy Qi to eliminate the accumulation. With the continuous updating of knowledge on tumors and tumor microenvironment， it is also recognized that there are "healthy Qi" and "pathogenic Qi" in the immune microenvironment of tumors. For example， the immune cells and immune factors that inhibit tumor growth can be classified as "healthy Qi" with TCM attributes， while those promoting tumor growth can be classified as "pathogenic Qi". Additionally， as proved by clinical data and experimental research， the elimination methods represented by "activating blood， resolving phlegm， and removing toxins" in the treatment of liver cancer can combat tumor cells and also regulate the "healthy Qi" and "pathogenic Qi" in the immune microenvironment of liver cancer to achieve the balance of Yin and Yang. Based on this， the present study reviewed from the TCM theory and the mechanisms of western medicine to provide theoretical support for the TCM treatment of malignancies by elimination methods and some ideas for TCM in tumor resistance.

Biological Basis of Invigorating Qi and Activating Blood Cirulation in Regulating Neural Repair After Ischemic Stroke： A Review / 中国实验方剂学杂志

Stroke is the leading cause of death and disability. Therefore， it is critical to develop the approaches for improving recovery and neural repair after stroke. Recovery after stroke involves complex interrelated systems of neural repair. The whole process of neural repair requires a series of coordinated interactions， such as response of neuronal cell body to traumatic stimuli， neural stem cell proliferation and migration， axoplasmic transport of signaling molecules， construction of cytoskeleton， and formation of axonal growth cone， to achieve regeneration and growth. As a potential new target for the treatment of neurologic defects， neural remodeling has important research significance in both the specific mechanism of neural repair and the clinical treatment of neurologic defects. After brain injury， single therapy is often ineffective due to the complex mechanism of internal repair， and thus comprehensive therapy becomes the development direction to improve the brain repair. Invigorating qi and promoting blood can promote nerve function remodeling after injury through neural protection， angiogenesis， neurogenesis， loop reconstruction， and cytokine regulation， playing a key role in nerve repair after stroke. Its mechanism is associated with autophagy， immunomodulation， and microRNA regulation， which fully embodies the multi-pathway， multi-target， and overall regulation characteristics of invigorating Qi and activating blood. Therefore， it is of theoretical and guiding significance to study the brain function rehabilitation after stroke by invigorating qi and activating blood.

Stasis Caused by Depression and Coronary Heart Disease / 中国实验方剂学杂志

Anxiety and depression are common comorbidities of coronary heart disease and are considered as independent risk factors in addition to traditional cardiovascular risk factors. Anxiety，depression and other mental abnormalities belong to the category of "depressive syndrome" of traditional Chinese medicine，which can lead to stasis of blood due to the lack of Qi flow. "Blood stasis" involves abnormal blood rheology， vascular endothelial dysfunction， chronic inflammatory response， abnormal lipid metabolism and other comprehensive pathological changes， and is the core pathogenesis of coronary heart disease in traditional Chinese medicine. "Depressive syndrome"can aggravate the development of coronary heart disease by promoting blood stasis in multiple ways. Prescriptions and herbs of promoting blood circulation and removing blood stasis can have a clinical effect by promoting blood circulation （improving physiological functions） and removing blood stasis （eliminating pathological changes）. In clinical practice， strengthening the screening of the mental and psychological status of patients with coronary heart disease and providing early and effective psychological interventions and combined Chinese and Western medicine drug treatment can significantly improve the clinical symptoms and prognosis of patients. This article was the first to put forward the academic view of "stasis caused by depression" for the first time，and discuss the modern biological research progress of "depression" in Chinese medicine that promotes blood stasis and aggravates coronary heart disease，in order to provide a basis for the subsequent development of Chinese medicine in the prevention and treatment of coronary heart disease. The aim is to provide a theoretical basis for the subsequent systematic research on the prevention and treatment of coronary heart disease with emotional abnormalities in Chinese medicine.

Mechanism of Chinese Herbal Compounds Capable of Invigorating Qi and Activating Blood in Intervention of Hematogenous Metastasis of Malignant Tumors： A Review / 中国实验方剂学杂志

Metastasis is the main cause of poor prognosis of malignant tumors， and intervention with metastasis is the key measure in the treatment of malignant tumors. Hematogenous metastasis， the most common tumor metastasis， falls into the category of "Chuanshe" in traditional Chinese medicine （TCM）， with Qi deficiency and blood stasis as the critical pathogenesis. In the fight against malignant tumors， TCM emphasizes the reinforcement of healthy Qi and the elimination of pathogenic factors， exhibiting its action advantages of multiple targets， multiple mechanisms， and multiple levels. Extensive clinical evidence has shown the exact efficacy of Chinese herbal compounds designed for invigorating Qi and activating blood in delaying the progression of tumor disease and prolonging the survival period of patients. In view of the important role of hematogenous metastasis in the prognosis of tumors， more and more studies have explored the effects and mechanisms of Chinese herbal compounds capable of invigorating Qi and activating blood in intervening in hematogenous metastasis. This paper summarized the relevant literature reports in China and abroad on the intervention of Chinese herbal compounds capable of invigorating Qi and activating blood in the hematogenous metastasis of malignant tumors， in order to provide a theoretical basis for the clinical application of Qi-invigorating and blood-activating therapy in the treatment of malignant tumors. It has been found that Chinese herbal compounds formulated for invigorating qi and activating blood are effective in hindering several key steps in hematogenous metastasis through various mechanisms， including regulating the expression of cell adhesion molecules， inhibiting extracellular matrix degradation and angiogenesis， enhancing the killing effect of immunity， and improving blood hypercoagulability and hyperviscosity. Furthermore， the combination of invigorating Qi and activating blood targets the pathogenesis essence （Qi deficiency and blood stasis， characterized by sthenia in origin and asthenia in superficiality） of malignant tumor much better. Some comparative studies have demonstrated that the anti-metastasis effect of Qi-invigorating and blood-activating therapy is significantly stronger than that of the Qi-invigorating or blood-activating therapy alone， and such combination avoids the possible risk of the metastasis of malignant tumors triggered by the use of either of them. This study has provided some reference for the current clinical application of TCM for improving the prognosis of malignant tumors.

Material basis and molecular mechanism of Angelicae Sinensis Radix in activating blood:based on computer-aided drug design / 中国中药杂志

Angelicae Sinensis Radix excels in activating blood, but the scientific mechanism has not been systematically analyzed, thus limiting the development of the medicinal. This study employed the computer-aided drug design methods, such as structural similarity-based target reverse prediction, complex network analysis, molecular docking, binding free energy calculation, cluster analysis, and ADMET(absorption, distribution, metabolism, excretion, toxicity) calculation, and enzyme activity assay in vitro, to explore the components and mechanism of Angelicae Sinensis Radix in activating blood. Target reverse prediction and complex network analysis yielded 40 potential anticoagulant targets of the medicinal. Gene Ontology(GO) term enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis indicated that the targets mainly acted on the complement and coagulation cascade signaling pathway to exert the anticoagulant function. Among them, the key enzymes thrombin(THR) and coagulation factor Xa(FXa) in coagulation cascade and thrombosis were the drug targets for thromboembolic diseases. At the same time, molecular docking and cluster analysis showed that the medicinal had high selectivity for FXa. According to binding free energy score, 8 potential active components were selected for enzyme activity assay in vitro. The results demonstrated that 8 components inhibited THR and FXa, and the inhibition was stronger on FXa than on THR. The pharmacophore model of 8 active compounds was constructed, which suggested that the components had the common pharmacophore AAHH. The ADMET calculation result indicated that they had good pharmacokinetic properties and were safe. Based on target reverse prediction, complex network analysis, molecular docking and binding free energy calculation, anticoagulant activity in vitro, spatial binding conformation of molecules and targets, pharmacophore model construction, and ADMET calculation, this study preliminarily clarified the material basis and molecular mechanism of Angelicae Sinensis Radix in activating blood from the perspective of big data, and calculated the pharmacology and toxicology parameters of the active components. Our study, for the first time, revealed that the medicinal had obvious selectivity and pertinence for different coagulation proteins, reflecting the unique effect of different Chinese medicinals and the biological basis. Therefore, this study can provide clues for precision application of Angelicae Sinensis Radix and the development of the blood-activating components with modern technology.

Efficacy-related substances of blood-activating and stasis-resolving medicinals derived from Curcuma plants: a review / 中国中药杂志

Derived from Curcuma plants, Curcumae Longae Rhizoma, Curcumae Rhizoma, Wenyujin Rhizoma Concisum, and Curcumae Radix are common blood-activating and stasis-resolving medicinals in clinical practice, which are mainly used to treat amenorrhea, dysmenorrhea, chest impediment and heart pain, and rheumatic arthralgia caused by blood stasis block. According to modern research, the typical components in medicinals derived from Curcuma plants, like curcumin, demethoxycurcumin, bisdemethoxycurcumin, curdione, germacrone, curcumol, and β-elemene, have the activities of hemorheology improvement, anti-platelet aggregation, anti-thrombosis, anti-inflammation, anti-tumor, and anti-fibrosis, thereby activating blood and resolving stasis. However, due to the difference in origin, medicinal part, processing, and other aspects, the efficacy and clinical application are different. The efficacy-related substances behind the difference have not yet been systematically studied. Thus, focusing on the efficacy-related substances, this study reviewed the background, efficacy and clinical application, efficacy-related substances, and "prediction-identification-verification" research method of blood-activating and stasis-resolving medicinals derived from Curcuma plants, which is expected to lay a theoretical basis for the future research on the "similarities and differences" of such medicinals based on integrated evidence chain and to guide the scientific and rational application of them in clinical practice.

Research progress of change of platelet in blood stasis syndrome and effect of traditional Chinese medicine / 中国中药杂志

The traditional Chinese medicine(TCM) syndrome of blood stasis refers to blood stagnation in meridians and viscera, with the main symptoms of pain, mass, bleeding, purple tongue, and unsmooth pulse. Cardiovascular and cerebrovascular diseases are among the major chronic diseases seriously harming the health of the Chinese. Among the coronary heart disease and stroke patients, most demonstrate the blood stasis syndrome. Platelet is considered to be one of the necessary factors in thrombosis, which closely relates to the TCM syndrome of blood stasis and the occurrence of cardiovascular and cerebrovascular diseases. The clinical and laboratory research on platelet activation and aggregation has been paid more and more attention. Its purpose is to treat and prevent blood stasis syndrome. In this study, the authors analyzed the research on the dysfunctions of platelets in blood stasis syndrome, biological basis of TCM blood stasis syndrome, and the effect of blood-activating stasis-resolving prescriptions on platelets, aiming at providing a reference for exploring the mechanism of platelet intervention in the treatment of TCM blood stasis syndrome and the pathways and targets of Chinese medicine in the prevention and treatment of the syndrome.

Research Progress on Pharmacological Effect of Astragali Radix-Angelicae Sinensis Radix on Invigorating Qi and Activating Blood / 中国实验方剂学杂志

Astragali Radix-Angelicae Sinensis Radix （AA） is a basic pair of drugs mainly targeting the syndrome characteristics of Qi and blood diseases. LI Dong-yuan's Danggui Buxuetang （DBT） is composed of AA， which is mainly used to tonify Qi and generate blood， with main indications of Qi deficiency and blood deficiency， blood heat and so on. It is favored by doctors because of its refined prescription and remarkable curative effect. However， there are many compatibility ratios of AA in different prescriptions in ancient books， and their efficacy and indications are also slightly different. This research showed that DBT also had the effect of invigorating Qi and activating blood， and the previous study of the group showed that 3∶1 compatibility ratio of the two herbs in the total amount of 36 g had more obvious effect of invigorating Qi and activating blood. By consulting the relevant literature， it was found that the drug pair had a certain effect of invigorating Qi and activating blood in various compatibility ratios such as 1∶1， 3∶1， 1∶5， 3∶2， 2∶1， 5∶1. The corresponding pharmacological effect mainly included regulating the energy metabolism of substances， regulating immune function， reducing blood viscosity， anti-oxidation stress， anti-inflammation， lowering blood lipids， lowering blood sugar， protecting heart function， protecting blood vessel wall， intervening angiogenesis， fighting against organ tissue fibrosis and so on. Regardless of the AA single-medicine's activating blood effect and the theory that "Qi circulation leads to blood circulation" or the drug pair's manifestation in modern pharmacological effects， all of these have confirmed that AA's effect of invigorating Qi and activating blood does exist， and the difference of action performance caused by different ratios of AA is closely related to dosage and proportion， which needs further study. Based on the study focusing on the effect of tonifying Qi and generating blood， it is easy to ignore the effect of invigorating Qi and activating blood， which limits the clinical application of the latter. Therefore， the tonifying Qi and activating blood circulation effect of the drug pair is reviewed in this paper， so as to provide a theoretical basis for its clinical rational drug use and related research.

Experimental Research Progress of Replenishing Qi and Activating Blood Circulation Traditional Chinese Medicine on Mitochondrial Quality Control in Treatment of Chronic Heart Failure / 中国实验方剂学杂志

Heart failure is a complex clinical syndrome，which is the final result of compensatory failure of heart injury caused by various reasons. Long-term persistent cardiac stress leads to mitochondrial dysfunction，which in turn further damages cardiomyocytes and leads to disease progression. Timely removal of damaged mitochondria in cardiomyocytes and maintaining a good living environment of viable mitochondria is not only an effective means to protect cardiomyocytes，but also a new way to prevent and treat heart failure and ventricular remodeling. Mitochondrial quality control is a series of cellular activities for mitochondria to maintain their structural and functional stability，including oxidative stress response，regulation of mitochondrial dynamics，mitochondrial autophagy，intracellular calcium regulation and so on. Traditional Chinese medicine（TCM） mostly uses drugs of replenishing Qi and activating blood circulation in the treatment of chronic heart failure，and Qi and mitochondria are similar in function. According to TCM，the performance of the body as "static，descending and inhibitory" in the case of Qi deficiency can also be compared with the energy defect of mitochondria. The classical method of tonifying qi and activating blood circulation in TCM can be applied here. In recent years，TCM takes mitochondria as the target and carries out many related experimental studies from the point of view of myocardial energy supply. It is found that Chinese herbs for replenishing Qi and activating blood circulation can participate in regulating the quality control mechanism of intracellular mitochondria with multiple targets and links. It is proved by experiments that Chinese herbs for replenishing Qi and activating blood circulation can exert myocardial protective effect through this mechanism.
