Novel technologies and models for studying pharmacological activities of traditional Chinese medicine for promoting blood circulation and removing blood stasis

OBJECTIVE Our previous studies demonstrated that various ingredients from the traditional Chinese medicine(TCM)for promoting blood circulation and removing blood stasis,as exemplified by cryptotanshinone and salvianolic acid B,exerted striking effects on modulating angiogenesis and vascular permeability,which suggests that they may be effective in treating vascular leak-driven diseases(e.g.tumor,cerebral cavernous malformation and diabetic retinopathy).However,the lack of reliable and advanced technologies and models sets up difficult hurdles for better understanding the role of TCM for promoting blood circulation and removing blood stasis.To this end,this study is to outline numerous cutting-edge platforms that can be utilized for exploring the function of TCM for promoting blood circulation and removing blood stasis in vascular leak-driven diseases.METHODS Two-photon laser scanning fluorescence microscopy was used to observe the interactions between neutrophils and blood vessels in a real-time manner.Dynamic flow system was employed to mimic the in vivo behaviors of neutrophils.RIP1-Tag5 spontaneous pancreatic cancer model was used to study the function of tumor blood vessels.CCM2ECKO(deletion of CCM2 in endothelial cells)mice were employed to establish the cerebral cavernous malformation(CCM)animal model.Micro-computed tomography(micro-CT)was utilized to assess the CCM lesion.Müller cell-knockout mouse model was used to study the progression of diabetic retinopathy.Vascular permeability in this model was assessed by fluorescein angiography.RESULTS The interactions between neutrophils and endothelial cells involve a series of complicated processes,including rolling,adhesion,intraluminal crawling and transmigration,which were all monitored in vivo by two-photon laser scanning fluorescence microscopy in a real-time manner.Dynamic flow system was capable of recapitulating the biological behaviors of neutrophils in vitro.Tumor vascular function in particular vascular perfusion could be assessed in the RIP1-Tag5 spontaneous pancreatic cancer model.In terms of CCM studies,specific deletion of CCM2 in endothelial cells resulted in the initiation of CCM lesion.The size and number of CCM lesions could be visualized and quantified by micro-CT.Furthermore,the Müller cell-knockout mouse model was able to precisely reflect the clinical symptoms of diabetic retinopathy.Vascular leak could be monitored at different time points using fluorescein angiography.CONCLUSION An array of high technologies and animal models can be used in investigating the occurrence and progression of multiple vascular leak-driven diseases.The pre-clinical and clinical studies of TCM for promoting blood circulation and removing blood stasis provide fundamental support for the application of the above-mentioned platforms,with the purpose of uncovering the scientific basis of TCM for promoting blood circulation and removing blood stasis.

Research Progress and Research Ideas on Anti-hepatic Fibrosis and Promoting Blood Circulation and Removing Blood Stasis of the National Drug Plumbapin Based on TLR4 Signal Pathway

Hepatic fibrosis is a reversible pathological phenomenon in the early and middle stages,but but no satisfactory intervention drugs have been available so far.Recent studies have suggested that microcirculation disturbance of liver is one of the important pathogenesis of chronic liver disease,the improvement of microcirculation is beneficial to the recovery of liver function and the delay of liver fibrosis.Hepatic stellate cells are the core cells of hepatic fibrosis,and also the most critical cells that affect the microcirculation of the liver.While TLR4/MyD88/NF-κB and TLR4/MyD88/MAPKs which are based on the action of hepatic stellate cells are two pathways that have very important influence on the inflammatory response of liver,the proliferation and apoptosis of hepatic stellate cells,and the secretion of fibrogenic cytokines.It was found that Plumbapin,the active ingredient of Guangxi specialty ethnic medicine,has the definite effect of promoting blood circulation and removing blood stasis and anti-hepatic fibrosis,but its mechanism is not clear.In this study,the research progress of the above problems was reviewed,and further research ideas were derived as follows:the pharmacological effect of Plumbapin on anti-hepatic fibrosis,promoting blood circulation and removing stasis was based on the influence of TLR4/MyD88/NF-κB and MAPKs signal pathway.

Research Progress and Research Ideas on Anti-hepatic Fibrosis and Promoting Blood Circulation and Removing Blood Stasis of the National Drug Plumbapin Based on W-P Body

Hepatic sinusoidal endothelial cells(HSEC)are the most important cells that constitute the microcirculation barrier of liver.Clinically,W-P bodies have been detected in the HSEC cells of most patients with liver fibrosis,and these bodies have become the synthesis and storage sites of vW factor,ET-1 and other factors of liver fibrosis;during pathological stimulation,W-P bodies will excrete the above factors into the cytoplasm,which can make the structure and function of HSEC maladjusted,cause the disturbance of liver microcirculation,and aggravate the process of liver fibrosis.However,previous studies have found that Plumbagin,the active ingredient of Guangxi specialty ethnic medicine,has the definite function of promoting blood circulation and removing blood stasis and anti-liver fibrosis,but its mechanism is not clear.In this study,the research progress of the above problems was reviewed,and further research ideas were derived from it as follows:the role of Plumbagin in promoting blood circulation and removing blood stasis and anti-liver fibrosis is produced by affecting the formation quantity of W-P bodies,affecting the synthesis and storage of the contents of W-P bodies,and interfering with their exocytosis ability.

Comparison of mechanisms and efficacies of five formulas for improving blood circulation and removing blood stasis

Objective This study aimed to compare the mechanisms and efficacies of five formulas that improve blood circulation and remove blood stasis.Methods(1)A network pharmacology method was used to determine the targets of five formulas that promote circulation and remove blood stasis.Compounds of the five formulas,namely Danshen Yin(丹参饮,DSY),Huoluo Xiaoling Dan(活络效灵丹,HLXLD),Shixiao San(失笑散,SXS),Taohong Siwu Tang(桃红四物汤,THSWT),and Xuefu Zhuyu Tang(血府逐瘀汤,XFZYT),were retrieved from the Traditonal Chinese Medicine System Pharmacology Database(TCMSP),the Shanghai Institute of Organic Chemistry of CAS,and the TCM Integrated Database.Drug target network was constructed by searching the Swiss Target Prediction database and the STITCH database.The target network of stasis was extracted from the PharmGKB database,the Online Mendelian Inheritance in Man(OMIM)database,the Genetic Association Database(GAD),and the Therapeutic Target Database(TTD).Candidate targets were determined using protein-protein interaction(PPI)network extension and topology selection.Thereafter,Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analysis was used to determine the differentiation of the mechanism of the five formulas.(2)Animal experiments were conducted to explore the efficacies of the five formulas in treating blood stasis.Seventy New Zealand rabbits were exposed to high-fat feeding+epinephrine injection to construct a blood stasis syndrome model.The rabbits were evenly divided into control,model,DSY,HLXLD,SXS,THSWT,and XFZYT groups.The latter five groups were orally administered the corresponding formulas[DSY:3.92 g/(kg·d),XFZYT:7.10 g/(kg·d),SXS:1.12 g/(kg·d),HLXLD:5.60 g/(kg·d),THSWT:4.48 g/(kg·d)].Serum lipid and blood rheology were analyzed,and pathology slices were observed.Results(1)A total of 269,358,288,370,and 376 candidate targets of DSY,HLXLD,SXS,THSWT,and XFZYT were obtained among which were 232 shared candidate targets.Fluid shear stress and atherosclerosis were the biological processes common to the five formulas.HLXLD,SXS,DSY,and THSWT regulated lipolysis in adipocytes,and XFZYT,HLXLD,SXS,and THSWT regulated the AGE-RAGE signaling pathway and complement and coagulation cascades.HLXLD,SXS,and XFZYT regulated the HIF-1 signaling pathway,DSY regulated the cGMP-PKG signaling pathway,HLXLD reduced platelet activation,SXS regulated the calcium signaling pathway,and XFZYT regulated the PPAR signaling pathway.(2)In the animal experiments,the values of total cholesterol(TC),triglyceride(TG),low density lipoprotein cholesterol(LDL),high density lipoprotein cholesterol(HDL),TC/HDL,and TG/HDL in each group decreased,among which the ones seen in XFZYT,HLXLD,and SXS groups were statistically significant(P<0.05).XFZYT presented the best effect,followed by HLXLD and SXS.XFZYT and HLXLD decreased apolipoprotein B100(apoB100)and increased apolipoprotein A1/apoB100(P<0.05).XFZYT decreased all the values of hematocrit(HCT),plasma viscosity,whole blood viscosity(WBV);HLXLD and SXS affected HCT;and DSY and THSWT regulated WBV(P<0.05).All the five formulas decreased the values of optical density and area of plaque,among which XFZYT and HLXLD showed statistical significance(P<0.05).Conclusion Adjusting fluid shear stress and alleviating the injury of endothelial cells might be the common mechanisms by which the five formulas promote blood circulation and remove blood stasis.Different formulas also have unique targets,which may provide guidance for clinical drug selection.By regulating different indices,the five formulas can regulate blood lipid and hemorheology,improve the state of blood stasis,and decrease the degree of aortic plaque in the blood stasis model rabbits.XFZYT and HLXLD had higher efficacies than DSY,THSWT,and SXS.

Objective: To observe the effect and clinical significance of circulating endothelial cells (CEC) in the pathogenesis of coronary heart disease with unstable angina pectoris (CHD-UAP), and to explore the protective effect of Chinese herbs for activating blood circulation, removing stasis and supplementing Qi (CH) on CHD-UAP patient's CEC. Methods: Sixty patients with diagnosis of CHD-UAP confirmed and differentiated to be Qi-deficiency and blood stasis by TCM were randomly divided into two groups and treated, on the basis of Western drug-therapy, with Tongxinluo capsule (通心络胶囊, TXL) and Huoxue Tongmai capsule (活血通脉胶囊, HXTM) respectively by way of oral taking three times a day, 3 capsules every time, with 1 month as one therapeutic course. The number of CEC in patients' blood circulation was counted before and after treatment. Besides, the number of CEC in 30 healthy persons was also counted for control. Results: The number of CEC in CHD-UAP patients was significantly higher than that in the healthy persons (P<0.01). After the patients were treated with CH, either TXL or HXTM, it significantly decreased (P<0.01)with insignificant difference between the two treated groups. Conclusion: CEC in CHD-UAP patients is severely damaged and endothelial function in disorder, Chinese herbs have protective effect on patients' CEC.

Research Progress and Prospects on the Anti-liver Fibrosis,Blood Circulation-promoting and Stasis-resolving Effects of Curcuma kwangsiensis Based on W-P Bodies

Liver fibrosis is a necessary stage in the progression of chronic liver disease to cirrhosis.So far,no satisfactory drugs have been found to intervene in liver fibrosis.Liver microcirculation disorders are one of the important pathogenesis of chronic liver disease,and hepatic sinusoidal endothelial cells(HSECs)are the main cells that constitute the liver microcirculation barrier.In clinical practice,W-P bodies have been detected in HSECs of most patients with liver fibrosis.W-P bodies serve as a site for the synthesis and storage of vW factors,ET-1 and other cytokines that promote liver fibrosis.They can disrupt the structure and function of HSECs,cause liver microcirculation disorders,and exacerbate the progression of liver fibrosis.Previous studies have found that the Guangxi specialty ethnic medicine,C.kwangsiensis S.G.Lee et C.F.Liang,has definite effects in promoting blood circulation,resolving blood stasis,and resisting liver fibrosis.Based on this,a further research idea has been derived,stating that the blood circulation-promoting,blood stasis-resolving,and anti-liver fibrosis effects of C.kwangsiensis are produced by affecting the formation of W-P bodies,the synthesis and storage of contents in W-P bodies,and intervening in their exocytosis capacity.

Revealing the material basis of MMP9-mediated activating blood and removing blood stasis drugs on Danshen-Ligusticum chuanxiong anti- vascular effect

Objective:Reveal the material basis and mechanism of angiogenesis effect of Danshen-chuanxiong herb-partners.Methods:The effective components of Danshen and chuanxiong were searched in the TCM System Pharmacology Database(TCMSP),and the drug targets were searched in the Swiss Target Prediction database;in the Disease-Gene Database(DisGeNET))Search for angiogenesis-promoting and inhibiting angiogenesis targets;use the protein interaction database(STRING)database and Cytoscape software to analyze the network core targets;use the DAVID database to enrich the drug-disease target intersection for GO and KEGG;RT-qPCR experiments verified the effect of luteolin on MMP9 gene expression;in vitro tube formation experiments analyzed the effect of luteolin on endothelial cell neovascularization.Results:After analysis,it is concluded that Danshen has 10 active ingredients and 50 angiogenesis targets;Chuanxiong has 2 active ingredients and 4 angiogenesis targets.The intersection of drug-taking targets yielded 9 targets,including AR,PARP1,MMP9,MMP2,MMP12,AKR1B10,ABCC1,CDK6,and STAT3.After analyzing the active ingredient-target network graph of Danshen/Chuanxiong,it was concluded that luteolin is the key chemical ingredient.After protein interaction(PPI)analysis,the results showed that MMP9 is the core target.The KEGG pathway is mainly enriched in 5 signaling pathways,the most important pathway is cancer-related pathways.There are 22 main biological processes of GO,which mainly involve collagen catabolism,protein extracellular matrix,metal endopeptidase activity,etc.The preliminary analysis of tubule formation experiment shows that luteolin inhibits angiogenesis and down-regulates the expression of MMP9 gene.Conclusion:Luteolin,the key chemical component of the Danshen-Ligusticum chuanxiong drug pair,inhibits angiogenesis by regulating the MMP9 target,and develops the reverse regulation of angiogenesis for the traditional Chinese medicine for promoting blood circulation and removing blood stasis on the basis of the known treatment of ischemic diseases.Provide a new perspective and theoretical basis for the use of Danshen and Chuanxiong medicine in clinical cancer patients.Reveal the material basis and mechanism of angiogenesis effect of Danshen-chuanxiong herb-partners.

Research Progress in Chinese Medicine Preparations for Promoting Blood Circulation and Removing Blood Stasis for Cirrhotic Patients with Portal Vein Thrombosis Following Splenectomy

This article presented an overview of the therapeutic effects of Chinese medicine(CM)preparations for promoting blood circulation and removing blood stasis for patients with portal vein thrombosis(PVT)after splenectomy.Based on published clinical researches of CM preparations for PVT after splenectomy in patients with cirrhotic portal hypertension(CPH),this paper evaluated the incidence of PVT,and explored potential active components and mechanisms of CM preparations.Safflower Yellow Injection,Danshen Injection,Danhong Injection,and Compound Danshen Dropping Pill achieved good curative effect alone or combined with anticoagulant therapy.In addition,Compound Biejia Ruangan Tablet and Anluo Huaxian Pill can also significantly improve the hemodynamic disorders of portal vein system in patients with cirrhosis.Considering the role of CM preparations in ameliorating the incidence of PVT after splenectomy in patients with CPH,we suggested that future research should provide more attention to CM alone or CM combined with anticoagulant for cirrhosis with PVT.

Efficacy and safety of activating blood circulation and removing blood stasis of Traditional Chinese Medicine for managing renal fibrosis in patients with chronic kidney disease:a systematic review and Meta-analysis

OBJECTIVE:To evaluate the efficacy and safety of activating blood circulation and removing blood stasis in terms of Traditional Chinese Medicine(TCM) for managing renal fibrosis(RF) in patients with chronic kidney disease(CKD).METHODS:We searched randomized controlled trials(RCTs) from eight databases.RESULTS:Sixteen eligible studies with 1,356 participants were included in this study.Compared to treatment with Western Medicine(WM) alone,the combined treatment with activating blood circulation and removing blood stasis in terms of TCM(ARTCM) and WM to manage RF in patients with CKD significantly ameliorated type Ⅳ collagen(C-Ⅳ)(SMD:-2.17,95% CI:3.01 to-1.34),type Ⅲ procollagen(PC-Ⅲ)(SMD:-1.08,95% CI:-1.64 to-0.53),laminin(LN)(SMD:-1.28,95% CI:-1.65 to-0.90),transforming growth factor β 1(TGF-β1)(SMD:-0.65,95% CI:-1.18 to-0.12),serum creatinine(Scr)(SMD:-1.36,95% CI:-1.85 to-0.87),blood urea nitrogen(BUN)(MD:-1.51,95% CI:-2.59 to-0.43),and 24 h urine protein(24h Upro)(SMD:-1.23;95% CI:-1.96 to-0.50).The level of hyaluronic acid(HA) was similar in both types of treatment(SMD:-0.74,95% CI:-1.91 to 0.44).The subgroup analysis showed that the duration of 8 weeks might affect the concentration of C-Ⅳ,PC-Ⅲ,and LN(P < 0.05).The effectiveness of the longer duration to C-Ⅳ,PC-Ⅲ,and LN was not certain.However,the result should be interpreted in care.The safety of the treatment using ARTCM and WM could not be evaluated because a few studies had reported adverse effects.The results of the Meta-analysis were not stable enough.There was publication bias for the reports on Scr(P = 0.001),C-Ⅳ(P = 0.001),PC-Ⅲ(P = 0.026),and LN(P = 0.030) and no publication bias for the reports on BUN(P = 0.293).The quality of evidence varied from low to very low.CONCLUSIONS:The combined treatment using ARTCM and WM to manage RF in patients with CKD has some advantages over treatment with WM alone.High-quality RCTs need to be conducted for the strong support.

Platelet proteomics and its advanced application for research of blood stasis syndrome and activated blood circulation herbs of Chinese medicine

The development of novel and efficient antiplatelet agents that have few adverse effects and methods that improve antiplatelet resistance has long been the focus of international research on the prevention and treatment of cardiovascular and cerebrovascular diseases.Recent advances in platelet proteomics have provided a technology platform for high-quality research of platelet pathophysiology and the development of new antiplatelet drugs.The study of blood stasis syndrome(BSS)and activated blood circulation of traditional Chinese medicine(TCM)is one of the most active fields where the integration of TCM and western medicine in China has been successful.Activated blood circulation herbs(ABC herbs)of Chinese medicine are often used in the treatment of BSS.Most ABC herbs have antiplatelet and anti-atherosclerosis activity,but knowledge about their targets is lacking.Coronary heart disease(CHD),BSS,and platelet activation are closely related.By screening and identifying activated platelet proteins that are differentially expressed in BSS of CHD,platelet proteomics has helped researchers interpret the antiplatelet mechanism of action of ABC herbs and provided many potential biomarkers for BSS that could be used to evaluate the clinical curative effect of new antiplatelet drugs.In this article the progress of platelet proteomics and its advanced application for research of BSS and ABC herbs of Chinese medicine are reviewed.

Exploration of the Effect and Mechanism of Activating Blood Circulation and Stasis-Removing Therapy on Tumor Metastasis

Metastasis is one of the specificities of late stage tumor and also a lethal factor often encountered. The study of tumor metastasis has important meaning for prolonging patients＇ survival and elevating their quality of life, but no really ideal prevention and treatment method has been found so far. Recent researches showed that tumor metastasis is correlated with platelet aggregation and blood hyperviscosity manner. Therefore, the early application of surgery, radiotherapy, chemotherapy and biological therapies, in combination with Chinese medicine therapy for activating blood circulation and removing stasis （ABCRS） may be, after all, an effective approach. ABCRS therapy is an important therapy of Chinese medicine, which, composed of several methods like smoothening blood flow in vessels, promoting blood circulation and dispersing stagnant blood, could influence tumor metastasis to different extents, and could coordinate with some other Chinese medicine therapeutic methods like supplementing qi, promoting qi, clearing heat, removing toxic substances, warming meridian, dispelling wind, eliminating dampness, nourishing yin, dissolving sputum, relieving stagnancy, emptying viscerals, etc. The effect and acting mechanism of ABCRS on tumor metastasis is summarized in this paper and its bi-directional regulatory effects discussed as well.

Potential advantages of a combination of Chinese Medicine and bone marrow mesenchymal stem cell transplantation for removing blood stasis and stimulating neogenesis during ischemic stroke treatment

Combined treatment of ischemic stroke with Chinese medicine and exogenous bone marrow mesenchymal stem cell(BMSC) transplantation may improve the removal of blood stasis and stimulation of neogenesis.Chinese medicines that remove blood stasis not only promote blood circulation but also calm the endopathic wind,remove heat,resolve phlegm,remove toxic substances and strengthen body resistance.The medicinal targeting effect of Chinese medicine can promote the homing of BMSCs,and the synergistic therapeutic effects of drugs can contribute to BMSC differentiation.As such,exogenous BMSC transplantation has potential advantages for neogenesis.Chinese medicines and exogenous BMSCs provide complementary functions for the removal of blood stasis and stimulation of neogenesis.Therefore,a combination of Chinese medicine and transplantation of exogenous BMSCs may be particularly suited to ischemic stroke treatment.

Objective： To investigate the efficacy and safety of the Chinese herbal therapeutic regimen of activating blood circulation （TRABC） in treatment of hypertensive intracerebral hemorrhage （HICH）. Methods： This was a multi-center prospective randomized open-label blinded-endpoint （PROBE） trial with HICH admitted to 12 hospitals. Totally 240 participants were randomized to the treatment group treated with TRABC in addition to conventional Western treatment or the control group with conventional Western treatment equally for 3 months. Primary outcome was degree of disability as measured by modified Rankin Scale （mRS）. Secondary outcomes were the absorption of hematoma and edema, National Institutes of Health Stroke Scale （NIHSS） scores and patient-reported outcome measures for stroke and Barthel activities of daily living index. Adverse events and mortality were also recorded. Results： After 3 months of treatment, the rate of mRS 0-1 and mRS 0-2 in the treatment group was 72.5% and 80.4%, respectively, and in the control group 48.1% and 63.9%, respectively, with a significant difference between groups （P〈0.01）. Hematoma volume decreased significantly at day 7 of treatment in the treatment group than the control group （P=0.038）. Average Barthel scores in the treatment group after treatment was 89.11 ＋ 19.93, and in the control group 82.18 ＋ 24.02 （P=0.003）. NIHSS scores of the two groups after treatment decreased significantly compared with before treatment （P=0.001）. Patient-reported outcomes in the treatment group were lower than the control group at day 21 and 3 months of treatment （P〈0.05）. There were 4 deaths, 2 in each group, and 11 adverse events, 6 in the treatment group and 5 in the control group. Conclusion： The integrative therapy combined TRABC with conventional Western treatment for HICH could promote hematoma absorption thus minimize neurologic impairment, without increasing intracerebral hematoma expansion and re-bleeding.
