[Methods]One hundred and ninety-seven patients with CHD and phlegm and blood stasis syndrome in our hospital from January 2016 to January 2018 were selected and randomly divided into two groups: control group( n =98) treated with aspirin plus atorvastatin,and research group( n =99) treated with DLT and aspirin plus atorvastatin for one month. The clinical efficacy and incidence of adverse reactions were observed. Serum secretory phospholipase A2( s PLA2),lipoprotein-associated phospholipase A2( LP-PLA2),oxidized low-density lipoprotein( ox-LDL),monocyte chemoattractant protein-1( MCP-1) and World Health Organization Quality of Life( WHOQOL-100) scores were compared before and after one month of treatment. [Results] The total effective rate was93. 94% in the research group,which was higher than that in the control group( 79. 59%,P < 0. 05);the levels of serum s PLA2,LP-PLA2,ox-LDL and MCP-1 in the research group were lower than those in the control group after one month of treatment( P < 0. 05). There was no statistical significance of the difference in the total incidence of adverse reactions between the research group and the control group( P > 0. 05).After one month of treatment,WHOQOL-100 scores were higher in two groups,which were higher in the research group than that in the control group( P < 0. 05). [Conclusions]DLT can significantly reduce the level of serum inflammatory factors,improve the quality of life in patients with CHD and phlegm and blood stasis syndrome.展开更多

New ideas need to be achieved for developing more efficacious and safe therapies to treat CHD. Chinese medicine (CM) uses multicomponent drugs to prevent disease and ameliorate symptoms based on patients' different syndromes. The benefit of CM in CHD has recently been proven by increasing clinical evidence. More importantly, linking CM syndrome differentiation and biomedical diagnosis might provide innovative thinking for treating CHD. According to epidemiological investigations, blood stasis syndrome (BSS) is the major type of syndrome in CHD. Investigating the biomedical mechanisms of BSS of CHD is a topic of CM research. Because the holistic perspective of systems biology is well matched with CM, the application of omics techniques and other integrative approaches appears inherently appropriate. A wide range of omics techniques, including transcriptomics and proteomics, have been used in studies of BSS of CHD to search for a common ground of understanding. These approaches could be useful for understanding BSS of CHD from clinical and biological viewpoints. Nevertheless, current studies mainly contain results from a single approach, and they have not achieved the holistic, systematic and integrative concept of system biology. Therefore, we discuss the progress and challenges in exploring the biomedical mechanisms of BSS of CHD by systems biology approaches. With further development of systems biology, a better platform to study BSS of CHD may be provided, and biomarkers for BSS of CHD and therapeutic targets may be found. The study of BSS of CHD by systems biology approaches will also be beneficial for developing personalized treatment for BSS of CHD patients.展开更多

Methods: CHD model was induced by a nameroid constrictor in Chinese miniature swine. Fifteen miniature swine were randomly divided into a model group(n=9) and a control group(n=6), respectively according to arandom number table. After 4 weeks, plasma hemorheology was detected by automatic hemorheological analyzer, indices including hematocrit, plasma viscosity, blood viscosity, rigidity index and erythrocyte sedimentation rate; cardiac function was assessed by echocardiograph to detect left ventricular end-systolic diameter(LVED), left ventricular end-diastolic diameter(LVEDd), ejection fraction(EF), fractional shortening(FS) and other indicators. Gas chromatography coupled with mass spectrometry(GC-MS) and bioinformatics were applied to analyze spectra of CHD plasma with BSS. Results: The results of hemorheology analysis showed significant changes in viscosity, with low shear whole blood viscosity being lower and plasma viscosity higher in the model group compared with the control group. Moreover, whole blood reduction viscosity at high shear rate and whole blood reduction viscosity at low shear rate increased significantly(P〈0.05). The echocardiograph results demonstrated that cardiac EF and FS showed significant difference(P〈0.05), with EF values being decreased to 50% or less. The GC-MS data showed that principal component analysis can clearly separate the animals with BSS from those in the control group. The enriched Kyoto Encyclopedia of Genes and Genomes biological pathways results suggested that the patterns involved were associated with dysfunction of energy metabolism including glucose and lipid disorders, especially in glycolysis/gluconeogenesis, galactose metabolism and adenosine-triphosphate-binding cassette transporters. Conclusion: Glucose metabolism and lipid metabolism disorders were the major contributors to the syndrome classification of CHD with BSS.展开更多

Methods: A total of 570 CHD patients(299 with BSS and 271 with non-BSS) and 317 controls were enrolled. The PAFR gene rs5938, rs313152 and rs76744145 polymorphisms were genotyped using the multiplex SNaP shot technology. The statistical analysis was conducted using a multiple variable logistic regression model. Results: Significant differences were detected in the genotypes frequency distributions of the rs5938(P<0.01), but not the rs313152(P>0.05), between the controls and CHD patients. Individuals with an rs5938 or rs313152 mutated allele had a low risk for CHD [adjusted odds ratio(aOR)=0.35, 95% confidence interval(CI): 0.23 to 0.56, P<0.01; aOR=0.65, 95% CI: 0.46 to 0.91, P<0.05, respectively]. After the CHD patients were stratified as BSS or non-BSS according to their Chinese medicine patterns, the rs5938 polymorphism mutated alleles had a significant association with a low risk for BSS of CHD(aOR=0.32, 95% CI: 0.18 to 0.57, P<0.01) and non-BSS of CHD(aOR=0.31, 95% CI: 0.17 to 0.55, P<0.01). The rs313152 polymorphism was associated with a low risk for BSS(aOR=0.51, 95% CI: 0.33 to 0.79, P<0.01), but not for non-BSS(aOR=1.22, 95% CI: 0.81 to 1.85, P>0.05). Furthermore, the interaction effect of the rs5938 and rs313152 polymorphisms for BSS of CHD was significantly based on an aOR value associated with the combination of the rs5938 GT genotype with the rs313152 TC genotype of 0.27(95% CI: 0.1 to 0.7, P<0.01). Conclusion: The PAFR gene rs5938 or rs313152 polymorphisms might be a potential biomarker for susceptibility to CHD, especially to BSS of CHD in Chinese Han population.展开更多

However, the main limitations of such interventions are drug resistanceand adverse reactions. Additionally, traditional biomarker discovery methods for CHD focus on the behavior ofindividual biomarkers regardless of their relevance. These limitations have led to attempting novel approachesto multi-dimensionally investigate CHD and identify safe and efficacious therapies for preventing CHD. Recently,the benefit of Chinese medicine (CM) in CHD has been proven by increasing clinical evidence. More importantly,linking CM theory with modern biomedicine may lead to new scientific discoveries. According to CM theory,all treatments for patients should be based on patients' syndromes. A recent epidemiological investigation hasdemonstrated that blood stasis syndrome (BSS) is the major syndrome type of CHD. BSS is a type of complexpathophysiological state characterized by decreased or impeded blood flow. Common clinical features ofBSS include a darkish complexion, scaly dry skin, and cyanosis of the lips and nails, a purple or dark tonguewith purple spots, a thready and hesitant pulse, and stabbing or pricking pain fixed in location accompaniedby tenderness, mass formation and ecchymosis or petechiae. The severity of BSS is significantly correlatedwith the complexity of coronary lesions and the degree of stenosis, and is an important factor affecting theoccurrence of restenosis after percutaneous coronary intervention. The mechanisms of BSS of CHD patientsshould be investigated from a modern medicine perspective. Although many studies have attempted toexplore the biomedical mechanisms of BSS of CHD, from hemorheological disorders to inflammation andimmune responses, the global picture of BSS of CHD is still unclear. In this article, the current status of studiesinvestigating the biomedical mechanisms of BSS of CHD and future perspectives are discussed.展开更多

Syndromes of Chinese medicine(CM) are lack of quantitative and easyimplementation diagnosis standards. To quantify and standardize the diagnosis of PBSS, scales are usually applied. Objective: To evaluate the diagnostic accuracy of CM diagnosis scale of PBSS in CHD. Methods: Six hundred patients with stable angina pectoris of CHD, 300 in case group and 300 in control group, will be recruited from 5 hospitals across China. Diagnosis from 2 experts will be considered as the "gold standard". The study design consists of 2 phases: pilot test is used to evaluate the reliability and validity, and diagnostic test is used to assess the diagnostic accuracy of the scale, including sensitivity, specificity, likelihood ratio and area under the receiver operator characteristic(ROC) curve. Discussion: This study will evaluate the diagnostic accuracy of CM diagnosis scale of PBSS in CHD. The consensus of 2 experts may not be ideal as a "gold standard", and itself still requires further study.(No. ChiCTR-OOC-15006599).展开更多

Methods: With case control design adopted, patients with the CHD (40 of BS, 37 of non-BS) and 39 healthy subjects for control, all fitting to the inclusion criteria, were selected in this study. The number of affected coronary branches was recorded by the contrast examination. The mean fluorescence intensity (MFI) of GPⅠb, GPⅡb-Ⅲa, and GMP-140 (CD42b, CD61, CD62p) in patients and healthy persons was measured with flow cytometry, the polymorphism of HPA-3 gene was detected by Taqman probe technique and that of HPA-2 gene was determined by gene sequencing. Results: MFI of CD61 and CD62p was higher in the CHD patients than in the healthy control, which was also higher in patients of BS syndrome than in patients of non-BS syndrome (P〈0.05); MFI of CD42b was lower in the CHD patients than in the healthy control (P〈0.05), but showing insignificant difference between BS and non-BS syndrome (P〉0.05); at the same time, no significant difference of all the above-mentioned three MFI could be found in patients with various numbers of affected coronary branches, neither in patients with different genotypes at GPⅡb HPA-3 and GPⅠb HPA-2 polymorphism loci (P〉0.05). Conclusion: (1) The activities of GP Ⅱ b-Ⅲa and GMP-140 were obviously increased in the genesis and developing process of CHD and CHD of BS syndrome, and so they could be taken as one of the objective indexes for microscopic diagnosis of BS syndrome. (2) The level of GPⅠb was lower in CHD patients than in healthy persons, but it was not a sensitive indicator for BS syndrome of CHD. (3) Levels of GP Ⅱb-Ⅲa, GPⅠb and GMP-140 were not related with the number of affected coronary branches in CHD patients. (4) The changes in amino-acids expression induced by the two loci brought no significant influence on GPⅠb and GP Ⅱb-Ⅲa activities.展开更多

Methods: Sixty subjects with ACS, whose pathogenesis changes belongs to qi disturbance blood stasis syndrome, were divided into 2 groups: 30 in the QSBS group and 30 in the QDBS group. The comparative analysis on them was carried out through comparing general information, coronary angiography and inflammatory factors including intracellular adhesion molecule-1(ICAM-1), chitinase-3-like protein 1(YKL-40) and lipoprotein-associated phospholipase A2(Lp-PLA2). Results: Compared with the QSBS group, Lp-PLA2 and YKL-40 levels in the QDBS group showed no-significant difference(P〉0.05); ICAM-1 was significantly higher in the QDBS group than in the QSBS group in the pathological processes of qi disturbance and blood stasis syndrome of ACS(P〈0.05). Conclusion: Inflammatory factor ICAM-1 may be an objective basis for syndrome typing of QSBS and QDBS, which provides a research direction for standardization research of CM syndrome types.展开更多

文摘The prevalence of coronary heart disease (CHD) is increasing, and has been a severe burden on society and family worldwide. New ideas need to be achieved for developing more efficacious and safe therapies to treat CHD. Chinese medicine (CM) uses multicomponent drugs to prevent disease and ameliorate symptoms based on patients' different syndromes. The benefit of CM in CHD has recently been proven by increasing clinical evidence. More importantly, linking CM syndrome differentiation and biomedical diagnosis might provide innovative thinking for treating CHD. According to epidemiological investigations, blood stasis syndrome (BSS) is the major type of syndrome in CHD. Investigating the biomedical mechanisms of BSS of CHD is a topic of CM research. Because the holistic perspective of systems biology is well matched with CM, the application of omics techniques and other integrative approaches appears inherently appropriate. A wide range of omics techniques, including transcriptomics and proteomics, have been used in studies of BSS of CHD to search for a common ground of understanding. These approaches could be useful for understanding BSS of CHD from clinical and biological viewpoints. Nevertheless, current studies mainly contain results from a single approach, and they have not achieved the holistic, systematic and integrative concept of system biology. Therefore, we discuss the progress and challenges in exploring the biomedical mechanisms of BSS of CHD by systems biology approaches. With further development of systems biology, a better platform to study BSS of CHD may be provided, and biomarkers for BSS of CHD and therapeutic targets may be found. The study of BSS of CHD by systems biology approaches will also be beneficial for developing personalized treatment for BSS of CHD patients.

文摘Objective: To investigate the underlying metabolomic profiling of coronary heart disease(CHD) with blood stasis syndrome(BSS). Methods: CHD model was induced by a nameroid constrictor in Chinese miniature swine. Fifteen miniature swine were randomly divided into a model group(n=9) and a control group(n=6), respectively according to arandom number table. After 4 weeks, plasma hemorheology was detected by automatic hemorheological analyzer, indices including hematocrit, plasma viscosity, blood viscosity, rigidity index and erythrocyte sedimentation rate; cardiac function was assessed by echocardiograph to detect left ventricular end-systolic diameter(LVED), left ventricular end-diastolic diameter(LVEDd), ejection fraction(EF), fractional shortening(FS) and other indicators. Gas chromatography coupled with mass spectrometry(GC-MS) and bioinformatics were applied to analyze spectra of CHD plasma with BSS. Results: The results of hemorheology analysis showed significant changes in viscosity, with low shear whole blood viscosity being lower and plasma viscosity higher in the model group compared with the control group. Moreover, whole blood reduction viscosity at high shear rate and whole blood reduction viscosity at low shear rate increased significantly(P〈0.05). The echocardiograph results demonstrated that cardiac EF and FS showed significant difference(P〈0.05), with EF values being decreased to 50% or less. The GC-MS data showed that principal component analysis can clearly separate the animals with BSS from those in the control group. The enriched Kyoto Encyclopedia of Genes and Genomes biological pathways results suggested that the patterns involved were associated with dysfunction of energy metabolism including glucose and lipid disorders, especially in glycolysis/gluconeogenesis, galactose metabolism and adenosine-triphosphate-binding cassette transporters. Conclusion: Glucose metabolism and lipid metabolism disorders were the major contributors to the syndrome classification of CHD with BSS.

文摘Studying the essence of a syndrome has been a key challenge in the field of Chinese medicine.Until now,due to limitations of the methods available,the progress towards understanding such complicated systems has been slow.Metabonomics encompasses the dynamics,composition and analysis of metabolites,enabling the observation of changes in the metabolic network of the human body associated with disease.Being from the point of view of the whole organism,metabonomics provides an opportunity to study the essence of a syndrome to an unprecedented level.Phlegm and blood stasis syndrome is the main syndrome associated with coronary heart disease(CHD),which bring difficulties in clinical treatment due to difficulties associated with differentiation of symptoms and signs.The fundamental differences of material between the two also need to be interpreted.The authors consider that we can use the method of combining a disease(in this case CHD)with associated syndromes(phlegm and blood stasis syndrome)to select patients with phlegm and blood stasis syndrome of CHD,and utilize metabonomics to explore the essence of the syndrome by difference analysis of metabolite spectra.Meanwhile,we can study the syndrome in CM,observe the change regularity of metabolism spectra after the treatment of corresponding and non-corresponding prescription and syndrome,in order to validate the material fundament in the progress of syndrome formation and their differences.This will not only have great significance in enhancing the ability to identify syndrome of phlegm and blood stasis in CHD and to establish the clinical curative criteria,but will also offer a new approach of studying the essence for a syndrome using metabonomics.

文摘Objective: To explore the association of the platelet-activating factor receptor(PAFR) gene rs5938, rs313152 and rs76744145 polymorphisms with coronary heart disease(CHD) and blood stasis syndrome(BSS) of CHD in Chinese Han population. Methods: A total of 570 CHD patients(299 with BSS and 271 with non-BSS) and 317 controls were enrolled. The PAFR gene rs5938, rs313152 and rs76744145 polymorphisms were genotyped using the multiplex SNaP shot technology. The statistical analysis was conducted using a multiple variable logistic regression model. Results: Significant differences were detected in the genotypes frequency distributions of the rs5938(P<0.01), but not the rs313152(P>0.05), between the controls and CHD patients. Individuals with an rs5938 or rs313152 mutated allele had a low risk for CHD [adjusted odds ratio(aOR)=0.35, 95% confidence interval(CI): 0.23 to 0.56, P<0.01; aOR=0.65, 95% CI: 0.46 to 0.91, P<0.05, respectively]. After the CHD patients were stratified as BSS or non-BSS according to their Chinese medicine patterns, the rs5938 polymorphism mutated alleles had a significant association with a low risk for BSS of CHD(aOR=0.32, 95% CI: 0.18 to 0.57, P<0.01) and non-BSS of CHD(aOR=0.31, 95% CI: 0.17 to 0.55, P<0.01). The rs313152 polymorphism was associated with a low risk for BSS(aOR=0.51, 95% CI: 0.33 to 0.79, P<0.01), but not for non-BSS(aOR=1.22, 95% CI: 0.81 to 1.85, P>0.05). Furthermore, the interaction effect of the rs5938 and rs313152 polymorphisms for BSS of CHD was significantly based on an aOR value associated with the combination of the rs5938 GT genotype with the rs313152 TC genotype of 0.27(95% CI: 0.1 to 0.7, P<0.01). Conclusion: The PAFR gene rs5938 or rs313152 polymorphisms might be a potential biomarker for susceptibility to CHD, especially to BSS of CHD in Chinese Han population.

文摘The medical community as a whole is attempting to start preventive therapy for coronary heartdisease (CHD) patients earlier in life. However, the main limitations of such interventions are drug resistanceand adverse reactions. Additionally, traditional biomarker discovery methods for CHD focus on the behavior ofindividual biomarkers regardless of their relevance. These limitations have led to attempting novel approachesto multi-dimensionally investigate CHD and identify safe and efficacious therapies for preventing CHD. Recently,the benefit of Chinese medicine (CM) in CHD has been proven by increasing clinical evidence. More importantly,linking CM theory with modern biomedicine may lead to new scientific discoveries. According to CM theory,all treatments for patients should be based on patients' syndromes. A recent epidemiological investigation hasdemonstrated that blood stasis syndrome (BSS) is the major syndrome type of CHD. BSS is a type of complexpathophysiological state characterized by decreased or impeded blood flow. Common clinical features ofBSS include a darkish complexion, scaly dry skin, and cyanosis of the lips and nails, a purple or dark tonguewith purple spots, a thready and hesitant pulse, and stabbing or pricking pain fixed in location accompaniedby tenderness, mass formation and ecchymosis or petechiae. The severity of BSS is significantly correlatedwith the complexity of coronary lesions and the degree of stenosis, and is an important factor affecting theoccurrence of restenosis after percutaneous coronary intervention. The mechanisms of BSS of CHD patientsshould be investigated from a modern medicine perspective. Although many studies have attempted toexplore the biomedical mechanisms of BSS of CHD, from hemorheological disorders to inflammation andimmune responses, the global picture of BSS of CHD is still unclear. In this article, the current status of studiesinvestigating the biomedical mechanisms of BSS of CHD and future perspectives are discussed.

文摘Background Phlegm and blood stasis syndrome(PBSS) is one of the main syndromes in coronary heart disease(CHD). Syndromes of Chinese medicine(CM) are lack of quantitative and easyimplementation diagnosis standards. To quantify and standardize the diagnosis of PBSS, scales are usually applied. Objective: To evaluate the diagnostic accuracy of CM diagnosis scale of PBSS in CHD. Methods: Six hundred patients with stable angina pectoris of CHD, 300 in case group and 300 in control group, will be recruited from 5 hospitals across China. Diagnosis from 2 experts will be considered as the "gold standard". The study design consists of 2 phases: pilot test is used to evaluate the reliability and validity, and diagnostic test is used to assess the diagnostic accuracy of the scale, including sensitivity, specificity, likelihood ratio and area under the receiver operator characteristic(ROC) curve. Discussion: This study will evaluate the diagnostic accuracy of CM diagnosis scale of PBSS in CHD. The consensus of 2 experts may not be ideal as a "gold standard", and itself still requires further study.(No. ChiCTR-OOC-15006599).

文摘Objective:To study the distribution of gelsolin in human platelet and plasma,and the association with blood-stasis syndrome(BSS) of coronary heart disease(CHD).Methods:Sixty patients with CHD(30 in BSS group and 30 in non-BSS group) and 30 healthy subjects(control group) were included in this study.The classification of the syndrome was based on clinical symptoms and signs.Gelsolin concentration in platelet rich plasma(PRP),platelet poor plasma(PPP),filamentous actin(F-actin) and group-specific component globulin (Gc-globulin) of PPP were determined by enzyme-linked immunosorbent assay(ELISA).The fluorescence intensity of CD62p and cytoplasmic calcium([Ca^(2+)]_i) in human platelets of patients and healthy persons was measured with flow cytometry.Results:Compared with the control group,gelsolin in PRP of the BSS group increased significantly(P0.01),while that in PPP of the BSS and non-BSS groups decreased markedly(P0.05), the CD62p,[Ca^(2+)]_i of platelet,F-actin,and Gc-globulin of the BSS and non-BSS groups increased significantly (P0.01).Compared with the non-BSS group,the gelsolin concentration in PRP of BSS group increased significantly(P0.01),the[Ca^(2+)]_i of platelet of the BSS group increased markedly(P0.01),while the F-actin and Gc-globulin of the BSS group had no statistical defference(P0.05).Conclusions:Gelsolin concentration in PRP was increased and accompanied by the elevated[Ca^(2+)]_i of platelet in CHD with BSS,while gelsolin in PPP were lowered markedly.We speculate that plasma gelsolin may clear F-actin from circulation,thus resulting in depletion of plasma gelsolin significantly.This,in addition to the increased calcium influx of platelets,may lead to the gelsolin abnormal expression on platelets during the process of BSS in CHD.Therefore,platelet gelsolin may serve as a new potential biomarker and a therapeutic target of BSS in CHD.

文摘Objective: To comparatively study the expressive conditions of platelet activation related factors (GPⅠb, GPⅡb-Ⅲa and GMP-140) in healthy subjects and patients with coronary heart disease (CHD) of blood-stasis (BS) or non-blood-stasis (non-BS) syndrome, and to analyze the relationship between the activities of various glycoproteins and the polymorphism of genes. Methods: With case control design adopted, patients with the CHD (40 of BS, 37 of non-BS) and 39 healthy subjects for control, all fitting to the inclusion criteria, were selected in this study. The number of affected coronary branches was recorded by the contrast examination. The mean fluorescence intensity (MFI) of GPⅠb, GPⅡb-Ⅲa, and GMP-140 (CD42b, CD61, CD62p) in patients and healthy persons was measured with flow cytometry, the polymorphism of HPA-3 gene was detected by Taqman probe technique and that of HPA-2 gene was determined by gene sequencing. Results: MFI of CD61 and CD62p was higher in the CHD patients than in the healthy control, which was also higher in patients of BS syndrome than in patients of non-BS syndrome (P〈0.05); MFI of CD42b was lower in the CHD patients than in the healthy control (P〈0.05), but showing insignificant difference between BS and non-BS syndrome (P〉0.05); at the same time, no significant difference of all the above-mentioned three MFI could be found in patients with various numbers of affected coronary branches, neither in patients with different genotypes at GPⅡb HPA-3 and GPⅠb HPA-2 polymorphism loci (P〉0.05). Conclusion: (1) The activities of GP Ⅱ b-Ⅲa and GMP-140 were obviously increased in the genesis and developing process of CHD and CHD of BS syndrome, and so they could be taken as one of the objective indexes for microscopic diagnosis of BS syndrome. (2) The level of GPⅠb was lower in CHD patients than in healthy persons, but it was not a sensitive indicator for BS syndrome of CHD. (3) Levels of GP Ⅱb-Ⅲa, GPⅠb and GMP-140 were not related with the number of affected coronary branches in CHD patients. (4) The changes in amino-acids expression induced by the two loci brought no significant influence on GPⅠb and GP Ⅱb-Ⅲa activities.

文摘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.
