This is one kind of social action logics of class driven by the class interests.The present new social movements and the theory of risk society have revealed another kind of social action logic driven by the value conception and class identity. Based on an analysis of the findings of a social survey conducted from Nov. To Dec. , 2002 in 31 big cities (the cities under the jurisdiction of central government and the capitals of provinces) in the mainland of China,this paper has proved the existence of this logic.The results of the analysis indicate that the class identity is the most important factor in influencing the social attitude and the intention of the social actor, but it is not determined by the economic income and the occupational status.展开更多

Data sources Information included in this article was identified by searching of PUBMED （1997-2006） online resources using the key term LOX-1. Study selection Mainly original milestone articles and critical reviews written by major pioneer investigators of the field were selected.

The pathophysiological functions of LOX-1 in several diseases were discussed. Conclusions Identification of LOX-1 and a definition of its biological role in pathophysiologic states provide deeper insight into the pathogenesis of some cardiovascular diseases especially in atherosclerosis and provide a potential selective therapeutic approach.
