AIM: To study the pathological change in mouse organs immunitied by inactivated SARS-CoV vaccine. METHODS: Inactivated SARS-CoV vaccine was injected into BALB/c and C57BL/6 mice. Anti-SARS antibody was analyzed by ELISA. After 8 weeks, the immunitied mice were killed and those organs were analyzed by pathological methods. RESULTS: Anti-SARS antibody in mice was positive after 8 days. Only minimal injury was observed in a few lungs and livers, but the other organs were not. CONCLUSIONS: Inactivated SARS-CoV vaccine induced mice to create antibody, whereas they did not cause severe injury. This result will be valuable for vaccine into clinical research. [

Objective:To investigate clinical characteristics of cerebrovascular disease complicated with secondary epilepsy in the elderly, and to provide the targeted health care measures.Methods:The 106 elderly patients with epilepsy secondary to cerebrovascular diseases treated in Three Gorges Hospital Affiliated to Chongqing University were enrolled as the epilepsy group, and another 106 patients with single cerebrovascular disease without secondary epilepsy during same period were included as the control group.Clinical features and epileptic seizure activity were observed and analyzed, and the targeted health care measures were developed.Results:The proportions of patients with cerebral hemorrhage, cerebral lobe infarction, cortical dysfunction and abnormal brain waves were higher in the epilepsy group [ 66.99%(71 cases), 68.87%(73 cases), 83.02%(88 cases), 70.75%(75 cases), respectively]than in the control group(43.40% or 46 cases, 46.23% or 49 cases, 61.32% or 65 cases, 53.77% or 57 cases)( χ2=11.921、11.121、12.424、6.505, all P<0.05). NFD scores before treatment had no significant difference between the epilepsy group and the control group(22.7±4.8 vs.23.4±5.1, t=1.029, P=0.152). NFD score after 3 months of treatment was higher in the epilepsy group than in the control group(14.3±2.9 vs.10.1±2.5, t=11.294, P=0.000). Conclusions:Epilepsy is a common complication of various cerebrovascular diseases, among which the cerebral hemorrhage is the most common.Polyloencephalopathy and cortical involvement can increase the risk of epilepsy in patients with cerebrovascular diseases.Therefore, it is very important to provide the necessary treatment and health care, so as to reduce the impact of epileptic seizure on the disease condition and improve prognosis in patients with cerebrovascular disease.
