Results The serum antibody level reached to 0.71±0.08-0.77±0.06 after genetic vaccine pCD-HCV1(100 μg/mouse) were inoculated into the mice(n=12) three or four times while blank vector pCD-SRα1 could not induce the mice(n=8) to generate antibody response in same way.After the antibody levels in mice(n=8) immunized by pCD-HCV1 had ascended to peak value(0.71), there was no trend of descending during the following 18 weeks of detection(0.68±0.06-0.75±0.07). Specific fragment of HCV cDNA identified by polymerase chain reaction from DNA extracted from the muscles of the mice after pCD-HCV1 had beed inoculated three months.

结果 基因疫苗pCD-HCV1(100 μg/只)3-4次接种小鼠后(n=12)，血清抗体水平达0.71±0.08-0.77±0.06，空载体pCD-SRα1免疫鼠血清抗体阴性；免疫鼠(n=8)抗体水平达高峰后(0.71)，持续检测18周未见下降趋势(0.68±0.06-0.75±0.07)；pCD-HCV1免疫小鼠3个月后，用聚合酶链反应仍可从肌肉组织中扩增出特异性HCV cDNA片段；免疫鼠PBMC对HCV合成肽CP9、基因重组抗原C、E1刺激后均出现增殖反应，刺激指数分别为4.07±1.58、3.88±0.70和3.69±1.30，与pCD-SRα1免疫鼠相比，差异有显著性(P.001)。

Methods A retrospective analysis was performed for images of CT,MRI and DSA of 12 patients with intracranial venous angiomas.In all cases,7 cases male,5 cases female,age ranged from 8 years old to 72 years old.All patients underwent the examinations of CT,MRI and/or DSA.Results All 12 patients had single lesion.In these cases,there were 6 cases （50%） located in cerebella,6 cases （50%） located in cerebra including 3 cases （25%） in lobus frontalis and 3 cases （25%） in lobus parietalis.Most patients had slight clinical symptoms and were detected the lesions accidentally when they were examined for other diseases.Compared the imaging features of CT,MRI and DSA,conventional CT scan was negative,but there were characteristic images which was "dendritic" sign in contrast-enhanced CT and MRI,and typical findings of "caput medusae"sign in venous phase of DSA.

结果 颅内静脉血管瘤均为单发；6例（50%）位於幕下小脑实质内，6例（50%）位於幕上额叶（3例25%）、顶叶（3例25%）脑实质内；患者临床症状轻微，多为合并其他病变检查时偶然发现；CT、MRI及DSA的影像比较，CT平扫为阴性，CT增强扫描与MRI平扫呈特征性表现，即树枝征，DSA静脉期可见典型表现蛇头征。
