Geneticist based on methylation plays an important role in elucidating disease gene and environment interaction. In this paper, we studied DNA methylation modification, magnetic field, molecular genetics and the relevance between TCM syndrome types and magnetic field intervention about the coronary heart disease (CHD) with blood stasis syndrome. To investigate the correlation between the internal and external magnetic field and the apparent genetic mechanism of CHD with blood stasis syndrome. It will provide thinking and methods for individual preventing and treating cardiovascular diseases fr...
