4.Adult Neurogenesis and Its Application in Ischemic Brain Injury Therapy (review)
Chinese Journal of Rehabilitation Theory and Practice 2006;12(8):656-658
Recent evidence has shown that neurogenesis occurs throughout adulthood, and neural stem cells reside in the adult central nervous system (CNS) in mammals. Experimental stroke in adult mammals increases neurogenesis from neural stem cells or progenitor cells located in the dentate subgranular zone and the subventricular zone lining the lateral ventricle. New neurons can migrate to the areas of damage regions and express morphological markers characteristic of died neurons. These findings bring hope for self-repair after brain injury. The author of this paper reviewed the adult neurogenesis and its regulation in vivo, and described evidence for stroke-induced neurogenesis and neuronal replacement in the adult, and discussed the future research directions about neurogenesis after stroke and other brain injuries.

Objective To summarize the funding of scientific research projects on obstetrics and gynecology by National Natural Science Foundation of China (NSFC) from 2007 to 2016 and to display the hotspots of scientific research on obstetrics and gynecology. Methods A systemic search was performed for the information of projects supported by NSFC from 2007 to 2016. The indicators for analysis included the number of projects, total investment, project categories, research units and research field. The research direction of each project was decided based on title, summary and key words provided by the profile of each project. Results The total investment on obstetrics and gynecology by NSFC was 23.214 million with a total of 82 projects in 2007. It increased year by year and reached the peak in 2014 (359 projects 208.990 million). The investment and number of projects remained stable after 2014. General projects (1109 projects 608.000 million) formed the majority of projects. Youth science fund projects (1035 projects 214.976 million) increased steadily and the number was nearly equal to general projects. There were only a small amount of key projects (20 projects 54.720 million) and major projects (7 projects 38.400 million). The investment varied in different research units. The greatest 10 units (less than 6% of total), including 7 comprehensive universities, 2 medical universities and 1 institute of medicine, got 1113 projects invested (43.84% of total,1113/2539). The hot areas like gynecological tumor (920 projects 350.615 million),hypertensive disorders complicating pregnancy (91 projects 37.470 million) and polycystic ovarian syndrome (77 projects 29.540 million) were more likely to receive investment, while some interdisciplinary science like maternal and child health (28 projects 12.050 million), imaging and biomedicine (37 projects 14.770 million) began to achieve attention in recent years. Conclusions The number of researches invested will be increased for the scientific research in obstetrics and gynecology especially the areas of research focus, although the amount allocated for each will be decreased relatively. Besides, multidisciplinary work will be performed so as to develop obstetrics and gynecology of China to a high level.
