ABSTRACT

Objective: To investigate the effects of Trimetazidine on mitochondrial proteomic alterations in heart failure rats with qi- deficiency and blood- stasis syndrome after myocardial infarction. Methods: Heart failure models were established by ligating the left anterior descending coronary artery of SD rats. Rats were randomly divided into sham group, model group, Trimetazidine group. 8 weeks after drug intervention, the mitochondrial proteomic alterations of myocardial tissue were detected by two-dimensional gel electrophoresis (2-DE) and matrix-assisted laser desorption/ ionization time- of- flight mass spectrometry (MALDI- TOF- MS). Furthermore, expression levels of part of the differentially expressed proteins were verified by western blot. Results: Compared with model group, 18 differentially expressed protein spots were detected in Trimetazidine group, 10 of which were successfully identified by MALDI-TOFMS. Bioinformatics analysis showed that these differential proteins were mainly associated with energy metabolism, stress reaction, oxidative damage, cyto-skeleton, cell differentiation and proliferation. Western blot results showed that the expression of Stress-70 protein and Nucleophosmin increased and the expression of ATP-αdecreased in model group. The expression of Stress- 70 protein and Nucleophosmin decreased and the expression of ATP- αincreased in Trimetazidine group, which showed the same results in proteomics. Conclusion: Trimetazidine can partly adjust proteomic alterations of myocardial mitochondrial in HF rats with qi-deficiency and blood-stasis syndrome, and its intervention mechanism may involve improving energy metabolism, relieving stress reaction and oxidative damage, as well as regulating cell differentiation and proliferation. The results of comparative proteomic analysis performed by using 2-DE and MALDI-TOF-MS are accurate, stable and reliable.

ABSTRACT

Objective: To probe into TCM pattern of primary hyperlipemia and its relationship with gender, age, BMI, laboratory indices such as TC,TG, LDL-C, HDL-C, ApoAI, ApoB of the 120 patients with primary hyperlipemia. Methods: Logistic regression analysis wan used to analyze the associativity of TCM syndrome and objective indexes of primary hyperlipemia. Results: Logistic regression analysis showed that TCM syndromes of primary hyperlipemia had some relation with laboratory indices. Conclusion: TCM syndromes of primary hyperlipemia had some relation with laboratory indices. The lipemia laboratory indices can be one of the objective basis of TCM diagnosis. The main syndromes were stagnation of phlegm-turbid and syndrome of yang deficiency of both of spleen and kidney, the main pathogenesis were deficiency of spleen and kidney, intermingled phlegm and blood stasis. The main treatment methods were invigorating spleen and tonifying kidney, supplementing qi and nourishing heart, promoting blood flow and dissipating phlegm.
