Objective To study curative effect of edaravone on acute severe brain injury through the observation of neuron-specific enolase( that is:NSE) changes.Methods 60 severe brain injury patients were randomly assigned into the treatment group (n=30 ) and the control group (n=30).Besides the routine treatment,edaravone was used in the treatment group for 7 days.The control group received the same treatment except edaravone.NSE were measured in the two groups before the treatment and at 1st,3rd,5th,7th day after the treatment.GCS was evaluated at 21 days.Results Compared the NSE before treatment and after three days,they had significant difference(P＜0.05,also between the two groups and the GCS after 21 days.they had no significant adverse drug reactions during the two groups of patients with medication.Conclusion Edaravone for patients with severe brain injury has a better treatment effect,medication safety,fewer adverse reactions from the mechanism of NSE at acute phase.

Objecfive To study the influence of edaravone therapy on semm levels of neuronspecific enolase (NSE)in the patients of severe brain trauma and assess the therapic effect of edaravone.Method Sixty patients of severe brain trauma were randomly assigned into the treatment group(n=30)and the control group(n=30).Besides the routine treatment in both groups.edaravone Was only used in the treatment group.NSE levels were measured in the two groups before treatment and at 1st,3rd,5th,7th day after treatment.Results NSE levels before treatment in treatment group and control group were(48.73±30.46)μg/L and (40.86±22.05)μg/L,respectively,there Was no statistical significance between two groups.NSE levels after treatment at 3rd,5th,7th day in the two groups were(34.16±15.08),(29.86±12.61),(29.93±14.77)μg/L and (27.42±10.07),(22.33±8.93),(21.17±9.67)μg/L,respectively,there were statistical significances between two groups and in the same group (P＜ 0.05 or ＜ 0.01 ). With the time of therapy extended,NSE levels declined progressively. There were no significant adverse drug reactions during the treatment period. Conclusions The influence of edaravone therapy on serum levels of NSE in the patients of severe brain trauma is significant,edaravone for patients with severe brain trauma has a better curative effect ,medication safety,and fewer adverse drug reactions during acute phase.

OBJECTIVETo evaluate the effectiveness of small interfering RNA (siRNA) on inhibiting severe acute respiratory syndrome (SARS)-associated coronavirus replication, and to lay bases for the future clinical application of siRNA for the treatment of viral infectious diseases.

METHODSVero-E6 cells was transfected with siRNA before SARS virus infection, and the effectiveness of siRNA interference was evaluated by observing the cytopathic effect (CPE) on Vero-E6 cells.

RESULTSFive pairs of siRNA showed ability to reduce CPE dose dependently, and two of them had the best effect.

CONCLUSIONsiRNA may be effective in inhibiting SARS-associated coronavirus replication.
