Biomedical Mechanisms of Blood Stasis Syndrome of Coronary Heart Disease by Systems Biology Approaches

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.
