文摘In both Traditional Chinese Medicine(TCM)and modern medicine,they agree that the integrity and healthy structure of the vascular endothelium are essential for normal hemodynamics.Damage to the vascular endothelium can quickly activate the extrinsic coagulation pathway by triggering the tissue factor(TF)and lead to coagulation.This damage,along with a loss of anticoagulant properties through antithrombinⅢ(ATⅢ),TF pathway inhibitors,and the protein C system,can result in a hypercoagulable state and even thrombosis.Hypercoagulability is not only a common feature of many cancers but also an important factor promoting tumor development and metastasis,which corresponds to the TCM theory of“blood stasis leading to tumors.”The pharmacological effects of heparin and aspirin have similarities with TCM's“activating blood circulation and removing blood stasis”theory in improving blood circulation,treating related diseases,and their anti-inflammatory effects.

文摘Background:Heat and Blood Stasis Syndrome(HBSS),a syndrome in traditional Chinese medicine is intrinsically linked to vascular endothelial injury.Taohe Chengqi Decoction(THCQT)is considered to treat diseases related to HBSS by improving inflammatory response,oxidative stress,and blood circulation disorder.This study aimed to elucidate the therapeutic effects and underlying mechanisms of THCQT on vascular endothelial injury induced by HBSS.Methods:LC-MS/MS was used to analyze the chemical components of THCQT.The intervention involved administering saline and appropriate drugs to rats via gavage for 21 days,followed by 24-h repeated tail vein injections of LPS to replicate the HBSS model.Pharmacodynamic assessments included measuring rat body temperature,hemorheology,coagulation function,fever mediators,inflammatory factors,vascular endothelial injury factors,and aortic histopathology to evaluate the preventive effect of THCQT on vascular endothelial injury caused by HBSS.Additionally,proteomics and transcriptomics analyses elucidated THCQT’s impact on mRNA and protein expression levels,further validated by quantitative real-time PCR and Western blot analysis.Results:THCQT was detected to contain 293 chemical components,and some active ingredients with high levels have anti-inflammatory,antioxidant,and inhibiting platelet aggregation properties.Pharmacodynamic results demonstrated that H-THCQT significantly suppressed the elevation of body temperature and downregulated TNF-α,cAMP,and PGE2 expression levels.Additionally,it attenuated the increase in WBV and PV,and prolonged APTT,PT,and TT.It enhanced the expression of NO and PGI2 in plasma,inhibiting ET-1 and TXA2 expression,thus ameliorating aortic pathological injury.Combined transcriptomics and proteomics analyses of the KEGG pathway suggest that the MAPK pathway is crucial in mitigating vascular endothelial injury induced by HBSS through THCQT administration.Furthermore,quantitative real-time PCR and Western blot analyses of the aorta indicated that THCQT inhibits the mRNA and protein phosphorylation levels of p38MAPK,ERK,and JNK in the MAPK signaling pathway of HBSS rats.Conclusion:Our work not only helps explore the common mechanism of THCQT in treating multi-system diseases induced by vascular endothelial injury due to HBSS but also provides a valuable research method for investigating the mechanisms underlying traditional Chinese medicine syndromes.

文摘Intracerebral hemorrhage(ICH) is a significant and growing threat to human health,with increasing incidence.Promoting blood circulation and removing blood stasis therapy(PBCRBS),a Traditional Chinese Medicine therapy,can be an adjuvant therapy to benefit patients with ICH by improving clinical efficacy.However,in theory,using PBCRBS to treat ICH carries the risk of hematoma enlargement and rebleeding,which has led to controversy over its application in ICH treatment.To demonstrate the effectiveness and safety of PBCRBS in treating ICH,this review first analyzes the pathological and physiological basis of ICH and secondly,the cascade of response after ICH and the involvement of cytokines and signaling pathways in this process.Finally,experimental and clinical studies on the treatment of ICH with PBCRBS over the past decade were retrieved from the Pub Med and China National Knowledge Infrastructure databases,and the content of these studies was used to summarize commonly used herbs with PBCRBS effects and their mechanisms of action.Through analysis,hypertension has been identified as the most common cause of ICH.Heme,interleukin,reactive oxygen species,coagulation promoting particles and other induced mass effects,inflammation,oxidative stress,and coagulation cascade reactions lead to brain damage following ICH.This review includes 56 experimental studies and 83 clinical studies summarizing 28 commonly used herbs,demonstrating the positive impact of PBCRBS as an adjuvant therapy for ICH.In summary,PBCRBS appears effective and safe for treating ICH.

文摘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.

文摘Amyotrophic lateral sclerosis(ALS)is associated with proteostasis collapse:ALS is an unrelenting neurodegenerative disease that is characterized by the loss of motor neurons in the brain and spinal cord,resulting in the progressive atrophy,and eventual paralysis,of skeletal muscles.Death due to respiratory failure usually occurs within 2-5 years from symptom onset.Approximately 90%of ALS cases are of unknown etiology and are termed sporadic ALS(sALS).The remaining 10%of ALS cases present with a family history(familial ALS;fALS)and are associated with genetic mutations in a range of over 20 functionally heterogeneous genes.Regardless of disease origin,the pathological hallmark of ALS is the accumulation of ubiquitylated protein inclusions in motor neurons and surrounding glial cells.The presence of these inclusions,compromised largely of misfolded and aggregated proteins,implies a collapse in proteostasis.Proteostasis refers to the maintenance of the proteome in a state of balance or equilibrium so that a cell can perform its proper function.
