The use of mobile phone as a most usual radiation emissivesource is so widespread in recent *** biological effects effects of EMFs,particularly on the central nervous system（CNS） have been the subject of a large number of experimental ***,whether or not these effects are harmful,still remains still controversial.20 - Hydroxyecdysone,which is found in the rhizomes,roots and the stems of many plants,is an ecdysteroid hormone that regulates molting in *** this present study,we investigated the effects of 900 MHz EMF on neural stem cells of Spraque - Dawley（SD） neonatal rat hippocampus in ***,we explored the neuroprtective effects of 20 - Hydroxyecdysone against EMF *** group cells were placed on the exposure platform but not exposed to EMF（power density:0mw/cm,2 h/day for 6 days or consecutive 12h） during the exposure *** groups were exposed to 900 MHz EMF（power density:1 mw/cm or 3 mw/cm,2 h/day for 6 days or consecutive 12h）. For every group,a matching group that was pre - treated with 16mg/L 20 - Hydroxyecdysone before EMF exposure was *** results showed that compared with sham exposure group（Omw/cm）,the ratio of apoptosis and of exposure groups cells were significantly increased（P<0.01 ）,and on condition of intermittent exposure（2h/d,for 6 days）,there were significant differences between the two exposure groups（ P<0.05）,with higher ratio in the 3mw/cm exposure *** exposure groups,in comparison to no-treatment exposure groups,the ratio of apoptosis of pre - treatment exposure groups with 20 - Hydroxyecdysone were obviously decreased（P<0.05）.Futhermore,the cloning efficiency and proliferation of NSCs were significantly reduced in exposure groups（P<0.05 ） and these effects of EMFs were significantly alleviated by 20 - Hydroxyecdysone（P<0.05 ）.Our results indicated that exposure to 900 MHz EMF may induce the apoptosis of neonatal rat hippocampal neural stem cells in vitro in the power -dependent manner.

1损伤控制神经外科的理念
损伤控制外科（damage control surgery，DCS）是近年创伤外科领域中提出的一个极有实用价值的外科救治原则，即在救治危重创伤患者的过程中，早期不进行复杂、完整的手术，而采用快捷、简单的操作，控制伤情的进一步恶化，使患者获得复苏的时间，侍患者一般情况好转或稳定后，择期进行完整、
