The fast development of nanomaterials supplies the theory basis and technique support to solve the problems in the field of food safety detection. By the combination with the functional nanomaterials and traditional detection methods, novel detection methods with higher sensitivity, high throughput and rapid detection time could be developed, which attracted much attention in the detection of microorganism, chemical residues and biological toxins. In this article, we summarize the recent progress of the application of the main functional nanomaterials in food safety.

Regeneration myocardium by stem cell transplantartion has become a focus in research areas of cardial vascular disease. This review deals the role of traditional Chinese medicine in stem cell threapy of ischemic heart disease, such as mobilizing bone marrow stem cells, promoting stem cell proliferation, survival, induced them to differentiate into cardiomyocytes, and so on, showing good application prospects.
