Background Asthma control in African Americans(AA)is considered more difficult to achieve than in Caucasian Americans(CA).The aim of this study was to compare asthma control over time among AA and CA children w hose asthma is managed per NAEPP(EPR-3)*** This was a one-year prospective study of children referred by their primary care physicians for better asthma care in a specialty asthma *** children received asthma care per NAEPP *** were compared between CA and AA children at baseline and then at three-month intervals for one *** Of the 345 children,ages 2-17 years(mean=6.2±4),220(63.8%)were CA and 125(36.2%)were *** were no significant differences in demographics other than greater pet ownership in CA *** baseline,AA children had significantly more visits to the Emergency Department for acute asthma symptoms(mean=2.3±3)compared to CA(1.4±23,P=0.003).There were no other significant differences in acute care utilization,asthma symptoms(mean days/month),or mean asthma control test(ACT)scores at base *** 3-6 months,in both groups,mean ACT scores,asthma symptoms and acute care utilization significantly improved(P<0.05 for all)and change over time in both groups was comparable except for a significantly greater decrease in ED visits in AA children compared to CA children(P=002).Conclusion Overall,improvement in asthma control during longitudinal assessment was similar between AA and CA children because of consistent use of NAEPP asthma care guidelines.

Hope on the (fruit) fly: the Drosophila wing paradigm of axon injury

引用

Neural Regeneration Research 2015年第2期10卷 173-175页

作者： Yanshan Fang nancy M. Bonini Interdisciplinary Research Center on Biology and Chemistry Shanghai Institute of Organic Chemistry Chinese Academy of Sciences Department of Biology University of Pennsylvania

Axon degeneration and regeneration are processes that are central to neural insults including spinal cord iniury, brain trauma, ischemia, infection, inflammation, neuro- degenerative diseases, and aging （Conforti et al., 2014）. Injured axons undergo progressive self-destruction, termed ＂Wallerian degeneration＂, which is named after August Volney Waller who was the first to describe de- generation of severed nerves in 1850 - the injured nerve fibers become fragmented like threaded beads and are gradually cleared away.
