Abstract:
OBJECTIVETo seek the special plasma molecule in unstable angina (UA) patients of qi deficiency and blood stasis syndrome (QDBS) and method for explore the proteomic specificity of the disease.
METHODSLC-MS(E) analysis was performed in UA patients of QDBS or non-QDBS and in healthy persons after the 6 proteins with optimal abundance in plasma being removed by polyclonal antibody affinity column (product of Agilent Co. USA).
RESULTSActin were found only expressed, and FN, ApoH and ANXA6 were found highly expressed in plasma of patients with UA-QDBS, suggesting they might be the special molecules for the disease. Moreover, as compared with health persons, SAA, CP, MYH11 and C6 showed high expression, and the 6 proteins, e.g. A1BG, ApoA4, GSN, HBB, HBD and TF, showed low expression in the plasma of UA-QDBS patients.
CONCLUSIONUA-QDBS might belong to a kind inflammatory reaction. There are simultaneous existence of myocardial injury, blood coagulation factor abnormality, lipid metabolic disorder and oxygen transport obstacle in patients of UA-QDBS, they influence and interact mutually. The newly discovered differential proteins might provide clues for studying or discovering new protein targets of angina relieving drugs. The new technique of label free quantitative proteomics is an efficient method for bio-marker research of diseases and syndromes.
