In this paper we consider infinite horizon backward doubly stochastic differential equations （BDS- DEs for short） coupled with forward stochastic differential equations, whose terminal functions are non-degenerate. For such kind of BDSDEs, we study the existence and uniqueness of their solutions taking values in weighted Lp（dx）¤L2（dx）space （p _〉 2）, and obtain the stationary property for the solutions.

Translational medicine is a new emerging medical practice comprising multidisciplinary research from basic sciences to clinical medicine. It is regarded as a two-way road： bench to bedside and bedside to bench, playing important roles in communications between basic and clinical scientists [1]. As a developing country with more than 1.3 billion people, China bears a complex disease spectrum. It is thus urgent for China to develop translational medicine to facilitate pre- diction, prevention, diagnosis, and treatment of diseases. With the energetic supports of governments and scientists, translational medicine in China has developed rapidly in recent years. The 12th issue of Science China Life Sciences in 2011 organizes a special issue--Translational medicine in China I： Perspectives from Chinese physicians and scien- tists [2], focusing on translational medicine in China with five reviews, making a comprehensive introduction to the current circumstance of translational medicine in China.

An energy-dissipation based viscoplastic consistency model is presented to describe the performance of concrete under dynamic loading. The development of plasticity is started with the thermodynamic hypotheses in order that the model may have a sound theoretical background. Independent hardening and softening and the rate dependence of concrete are described separately for tension and compression. A modified implicit backward Euler integration scheme is adopted for the numerical computation. Static and dynamic behavior of the material is illustrated with certain numerical examples at material point level and structural level, and compared with existing experimental data. Results validate the effectiveness of the model.
