When nifedipine was used, Ppv, WHVP, MAP and HR were significantly decreased (P＜0.05), and the MVPG unchanged (P＞0.05). After administration of RSM, RSM+nifedipine and RSM+Hirudin+Nifedpin for 10-12 weeks, the diameter of portal vein (Dpv), spleen vein (Dsv), the portal venous flow (Qpv) and splenic venous flow (Qsv) in patients with hepatic cirrhosis were significantly lowered (P＜0.05-0.01), and the effect of RAS was weaker.CONCLUSIONS The efficacy of decreasing Ppv by Chinese herbs-RSM, RAS, etc. as compared with nifedipine, demonstrated that the Chinese herbs were slower in action than that of nifedipine, but more long-lasting and without side effects. Hence, long-term administration of Chinese herbs, would be more beneficial.展开更多

文摘Background:Panacis Quinquefolii Radix(PQR)is known for its ability to nourish“Qi”(it serves as the driving force for the functional activities of the body’s organs and meridians,promoting and regulating various physiological functions)and“Yin”(it represents the material foundation of the human body.It plays a role in nourishing,moistening,and cooling the body).Notoginseng Radix et Rhizoma(NRR)is recognized for its properties of resolving blood stasis(it refers to a pathological condition characterized by impaired or stagnant blood circulation within the body).Changes in the compatibility ratio of these herbs often lead to variations in their chemical composition and efficacy.However,the specific alterations in chemical composition and efficacy resulting from compatibility adjustments remain unclear.We aimed to compare the material basis and their effects of different compatibility ratios of PQR and NRR on“Qi”deficiency and blood stasis syndrome(QBS).Methods:This study employed UPLC-Q/TOF-MS to identify effective compounds in the compatibility of PQR and NRR and utilized UPLC-TQ-MS/MS to analyze the dissolution of 16 saponins in PQR and NRR at 9 different ratios.A rat model of QBS was established,and the efficacy of PQR and NRR in treating this syndrome was assessed using hemorheology and coagulation analyses.Results:The study results show that PQR and NRR exhibit significant efficacy,effectively reducing blood viscosity induced by platelet aggregation and lowering inflammatory markers such as IL-6,IL-10,TXB2 and ET associated with vascular injury.Moreover,this combination regulates ATP and ADP levels,enhances energy metabolism,and promotes overall health.A total of 104 compounds in the compatibility of PQR and NRR were identified.The ratios of 1:2 and 1:3 showed the highest total saponin content,but the ratio of 1:1 demonstrated a superior pharmacological effect for the treatment of QBS.Conclusion:In summary,the compatibility of PQR and NRR not only shows the complex interactions between traditional Chinese medicinal materials,but also provides a new idea and method for the treatment of QBS.

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Objective To explore the clinical characteristics and methods for syndrome differentiation prediction,as well as to construct a predictive model for Qi deficiency and blood stasis syndrome in patients with acute ischemic stroke(AIS).Methods This study employed a retrospective case-control design to analyze patients with AIS who received inpatient treatment at the Neurology Department of The First Hospital of Hunan University of Chinese Medicine from January 1,2013 to December 31,2022.AIS patients meeting the diagnostic criteria for Qi deficiency and blood stasis syndrome were stratified into case group,while those without Qi deficiency and blood stasis syndrome were stratified into control group.The demographic characteristics(age and gender),clinical parameters[time from onset to admission,National Institutes of Health Stroke Scale(NIHSS)score,and blood pressure],past medical history,traditional Chinese medicine(TCM)diagnostic characteristics(tongue and pulse),neurological symptoms and signs,imaging findings[magnetic resonance imaging-diffusion weighted imaging(MRI-DWI)],and biochemical indicators of the two groups were collected and compared.The indicators with statistical difference(P<0.05)in univariate analysis were included in multivariate logistic regression analysis to evaluate their predictive value for the diagnosis of Qi deficiency and blood stasis syndrome,and the predictive model was constructed by receiver operating characteristic(ROC)curve analysis.Results The study included 1035 AIS patients,with 404 cases in case group and 631 cases in control group.Compared with control group,patients in case group were significantly older,had extended onset-to-admission time,lower diastolic blood pressure,and lower NIHSS scores(P<0.05).Case group showed lower incidence of hypertension history(P<0.05).Regarding tongue and pulse characteristics,pale and dark tongue colors,white tongue coating,fine pulse,astringent pulse,and sinking pulse were more common in case group.Imaging examinations demonstrated higher proportions of centrum semiovale infarction,cerebral atrophy,and vertebral artery stenosis in case group(P<0.05).Among biochemical indicators,case group showed higher proportions of elevated fasting blood glucose and glycated hemoglobin(HbA1c),while lower proportions of elevated white blood cell count,reduced hemoglobin,and reduced high-density lipoprotein cholesterol(HDL-C)(P<0.05).Multivariate logistic regression analysis identified significant predictors for Qi deficiency and blood stasis syndrome including:fine pulse[odds ratio(OR)=4.38],astringent pulse(OR=3.67),superficial sensory abnormalities(OR=1.86),centrum semiovale infarction(OR=1.57),cerebral atrophy(OR=1.55),vertebral artery stenosis(OR=1.62),and elevated HbA1c(OR=3.52).The ROC curve analysis of the comprehensive prediction model yielded an area under the curve(AUC)of 0.878[95%confidence interval(CI)=0.855-0.900].Conclusion This study finds out that Qi deficiency and blood stasis syndrome represents one of the primary types of AIS.Fine pulse,astringent pulse,superficial sensory abnormalities,centrum semiovale infarction,cerebral atrophy,vertebral artery stenosis,elevated blood glucose,elevated HbA1c,pale and dark tongue colors,and white tongue coating are key objective diagnostic indicators for the syndrome differentiation of AIS with Qi deficiency and blood stasis syndrome.Based on these indicators,a syndrome differentiation prediction model has been developed,offering a more objective basis for clinical diagnosis,and help to rapidly identify this syndrome in clinical practice and reduce misdiagnosis and missed diagnosis.

文摘Objective:To examine the relationship between metabolic syndrome(MS)and its key components in granulomatous mastitis(GM),we explored potential pathological mechanisms through the lens of traditional Chinese medicine(TCM),particularly the concept of intermingled phlegm-blood stasis.Methods:In this retrospective study,we enrolled 172 patients with GM and 164 patients with non-inflammatory benign breast masses.Metabolic indicators(waist circumference[WC],blood lipids,etc.),inflammatory markers(C-reactive protein,interleukin-6,tumor necrosis factor-α),and adipose tissue CD68 expression were measured.Logistic regression was used to analyze risk factors and receiver operating characteristic curves were used to evaluate diagnostic efficacy.The correlation between TCM pathogenesis and biomarkers was also examined.Results:MS prevalence was significantly higher in the GM group than in the controls(26.16%vs.6.10%,P<.001).Multivariate analysis identified abdominal obesity(WC≥80 cm,odds ratio[OR]=1.065)and low levels of high-density lipoprotein cholesterol(HDL-C;<1.29 mmol/L,OR=0.066)as independent risk factors for GM(P<.001 for both).Among patients with GM,HDL-C levels were inversely correlated with inflammatory markers(r=−0.341 to−0.440),whereas patients with concurrent MS demonstrated greater CD68 macrophage infiltration(P<.001).According to TCM,abdominal obesity corresponds to“spleen deficiency with phlegm-dampness accumulation,”and low HDL-C reflects“deficiency of vital qi,”which collectively lead to phlegm-blood stasis obstruction in the mammary collaterals;this aligns with the key MS driving mechanisms of chronic inflammation and immune dysregulation.Conclusion:MS promotes GM development through chronic inflammation and immune dysregulation,with abdominal obesity and low HDL-C levels serving as core risk factors.The TCM theory of intermingled phlegm-blood stasis provides a novel interpretation of the metabolic-inflammatory mechanisms underlying GM.Accordingly,we propose phlegm-resolving and blood-activating strategies as potential therapeutic approaches for metabolic-immune axis regulation.

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.

文摘OBJECTIVE:To evaluate the clinical efficacy of Traditional Chinese Medicine prescriptions for resolving phlegm in the treatment of angina pectoris of phlegmstasis coronary heart disease by a network Meta-analysis.METHODS:Randomized controlled trials(RCTs)on clinical efficacy of CHD angina pectoris with interaction of phlegm and blood stasis were searched in PubMed,Springer,the Cochrane Library and Chinese-language databases China National Knowledge Infrastructure,China Science and Technology Journal Database,and Wanfang Data from their inception to December 2021.Literature was screened and literature bias risk was assessed by RevMan5.4 software.The overall response rate,the duration of angina attack,the levels of serum lipids such as total cholesterol(TC),triglyceride(TG),low density lipoprotein cholesterol(LDL-C),and high density lipoprotein cholesterol(HDL-C),and expression of hypersensitive C-reactive protein(hs-CRP)were selected as outcome indicators for network Meta-analysis and mapped using Stata15.1 software.RESULTS:Totally,26 RCTs were included,involving 2098 participants.There were 6 TCM formulas with the effects of dispelling phlegm and removing blood stasis.Taking conventional Western Medicine as the common intervention measures,the results showed that the overall response improvement rate from high to low was displayed as modified Xiaoxianxiong decoction(小陷胸汤,MXD),Danlou tablet(丹蒌片,DT),modified Gualou Xiebai Banxia decoction(瓜蒌薤白半夏汤,MGXBD),modified Wendan decoction(温胆汤,MWD),modified Zhishi Xiebai Guizhi decoction(枳实薤白桂枝汤,MZXGD),and modified Erchen decoction(二陈汤,MED).The sequence of angina attack duration improvement from high to low was MZXGD,MGXBD,DT,MWD,MXD.The sequence of TC improvement from high to low was MZXGD,MED,DT,and MGXBD.Sequence of improving TG from high to low was MED,MZXGD,MGXBD,and DT.For LDL-C improvement,the effect from good to poor was MZXGD,MGXBD,DT,and MED.With regard to HDL-C improvement,the effect was ranked as MED,MZXGD,MGXBD,and DT from good to poor.hs-CRP expression from high to low was MZXGD,MXD,MED,MWD,and MGXBD.CONCLUSION:TCM formula with the effects of dispelling phlegm and removing blood stasis combined with conventional Western Medicine has obvious advantages in treating CHD angina pectoris with interaction of phlegm and blood stasis.MZXGD has great potential in increasing the overall response rate,reducing Duration of angina attack improving blood lipids,and reducing inflammatory factors.However,due to the limitations of extant studies,the conclusions of this study need to be confirmed by numerous reasonably-designed RCTs.
文摘AIM To study the effects of Radix Salviae Militiorrhiza (RSM), other blood-activating and stasis-eliminating Chinese herbs on hemodynamics of portal hypertension.METHODS Portal pressure of cirrhotic dogs after chronic common bile duct ligation was measured directly; portal blood flow in patients with liver cirrhosis were detected by ultrasound Doppler.RESULTS After administration of RSM and Radix Angelicae Sinensis (RAS) by intravenous infusion in cirrhosis dogs, the portal venous pressure (Ppv), wedge hepatic venous pressure (WHVP), hepatic venous pressure gradient (HVPG), were significantly decreased (P＜0.05-0.01), but the mean arterial pressure (MAP), and the heart rate (HR) remained unchanged. When nifedipine was used, Ppv, WHVP, MAP and HR were significantly decreased (P＜0.05), and the MVPG unchanged (P＞0.05). After administration of RSM, RSM+nifedipine and RSM+Hirudin+Nifedpin for 10-12 weeks, the diameter of portal vein (Dpv), spleen vein (Dsv), the portal venous flow (Qpv) and splenic venous flow (Qsv) in patients with hepatic cirrhosis were significantly lowered (P＜0.05-0.01), and the effect of RAS was weaker.CONCLUSIONS The efficacy of decreasing Ppv by Chinese herbs-RSM, RAS, etc. as compared with nifedipine, demonstrated that the Chinese herbs were slower in action than that of nifedipine, but more long-lasting and without side effects. Hence, long-term administration of Chinese herbs, would be more beneficial.

文摘OBJECTIVE: To evaluate the anti-platelet aggregation effects of extracts from 31 Traditional Chinese Medicines(TCM) with the property of activating blood and resolving stasis in terms of TCM theory.METHODS: The 31 TCMs extracts were prepared using water, 90% ethanol and ethyl acetate., and the effects on anti-platelet aggregation were tested on a platelet aggregation analyzer in vitro with adenosine 5'-diphosphate, bovine thrombin and arachi-donic acid(AA) as aggregation inducers, respectively. Aspirin was the positive control.RESULTS: Lots of the tested TCMs had inhibitory effects with concentration-dependent manner on platelet aggregations induced by various agonists.Especially, some of the TCMs such as Chuanxiong(Rhizoma Chuanxiong), Yanhusuo(Rhizoma Corydalis Yanhusuo) and Danshen(Radix Salviae Miltiorrhizae) showed good anti-platelet aggregation effect similar or higher than that in positive control group.CONCLUSION: The study provided scientific references that several TCMs such as Chuanxiong(Rhizoma Chuanxiong), Yanhusuo(Rhizoma Corydalis Yanhusuo) and Danshen(Radix Salviae Miltiorrhizae),possess the property of anti-platelet aggregation.
