This paper will attempt to analyze the long-term economic impact of population aging. After discussing its impact on employment, domestic consumption, social security programs and public finance, rural-urban migration and urbanization, the Chinese economy＇s comparative advantage in international markets and structural change in industry, we suggest alternative policies of gradually relaxing the fertility control policy, assigning higher priority to the development of human capital, raising the compulsory retirement age, and improving the equity and efficiency of social security programs.展开更多

Because of the fact that there is still no specific treatment for perinatal brain lesions due to the complexity of neonatal hypoxic-ischemic pathophysiology, the search of new neuroprotective therapies is of great interest. In this regard, therapeutic possibilities of the endocannabinoid system have grown lately. The endocannabinoid system modulates a wide range of physiological processes in mammals and has demonstrated neuroprotective effects in different paradigms of acute brain injury, acting as a natural neuroprotectant. Concerning perinatal asphyxia, the neuroprotective role of this endogenous system is emerging these years. The present review mainly focused on the current knowledge of the cannabinoids as a new neuroprotective strategy against perinatal hypoxic-ischemic brain injury.展开更多
