Objective To explore the protective effect of astragalus injection(黄芪注射液)on cerebral cells after craniocerebral injury.Methods Sixty male Sprague-Dawley(SD)rats were randomly divided into five groups(each n=12).In the control group,only anesthesia and cranial bone surgery was performed, which did not impact on dura mater.In the model group,a freefall method was used to cause the left parietal lobe of brain limited contusion and saline was given.In the low,medium and high-dose astragalus injection (5,10,20 ml/kg)treatment groups,astragalus injection was injected intraperitoneally after injury at 30 minutes and 12 hours after injury respectively.After 24 hours of injury in each group,the rats were executed.The brain tissue from contusion was taken out and content changes of Ca~(2+),Mg~(2+),glutamate (Glu)and plasma endothelin(ET)were measured.Results In the model group,the Ca~(2+),Glu and ET contents in the rat brain tissues were significantly higher,but Mg~(2+)content was markedly lower than that of the control group(all P0.05).Conclusion Astragalus has a protective effect on nerve cells after craniocerebral injury.

Objective To observe the therapeutic effect of ketogenic diet therapy for children with intractable epilepsy and its safety.Methods Fifteen patients with intractable epilepsy were treated with ketogenic diet that was modified specifically for Chinese people.The compliance,seizure frequency and side effects were followed up.Results Twelve patients maintained on the treatment for 1 month.Among them,the reduction of seizure frequency in 10 patients exceed 50%.Ten patients maintained on the treatment for 3 months.Among them,the reduction of seizure frequency in 8 patients exceed 50%.Five patients maintained on the treatment for more than 6 months.The reduction of seizure frequency all exceed 50%.The reduction of seizure frequency in 4 patients exceed 90%.The seizures of 3 patients were controlled completely.Ten patients among all cases had various adverse effect,such as nausea,vomiting,diarrhea,constipation,hypoglycemia(nonsymptomatic),hyperlipemia and damage of liver function and so on,which could eliminate by anti-symptomatic treatment.Conclusions Ketogenic diet is effective and safe in Chinese children with intractable epilepsy with modified methods specifically for Chinese.The effect is unrelated with seizure types obviously.
