Because different cell lines may show various levels of susceptibility to adenovirus infection and virus production, non-selectively replicating wtAd5 was used to be a comparison with the tested conditionally replicating adenovirus CNHK500.ONYX-015, the first replication-competent adenovirus entered into clinical trials was also used to be a comparison. We used virus proliferation assay, cell viability assay and western blot to evaluate the proliferation and cytolysis selectivity of CNHK500. Results demonstrated that the CNHK500 virus proliferation multiples in breast cancer cell lines after 48 hours is similar to that of wtAd5, ONYX-015 virus proliferation ability is less than that of CNHK500 in cancer cells.

Was simultaneously injected into cisterna magna at the second injection blood in the presence of subarachnoid blood. At 2 to 4 days, GFP was expressed in leptomeninges over the brain stem, cortex and cerebral arteries, smooth muscle cells of small vessels were occasionlly transduced. GFP was expressed in adventitia of spastic basilar artery on days 2 (day 5 after first injection blood) after injection 〓, but was undetectable by days 4, transgene was not expressed in medial or intimal layers. The prensence of subarachnoid blood can not prevent access of adenovirus to vessels and transgene expression.
注入腺病毒载体后2天（初次注血第5天）行荧光显微镜、免疫组织化学和RT-PCR检测，结果在颅内大血管如基底动脉的外膜可见外源基因的表达，而外源基因不能转移至血管中膜和内膜，4天时（初次注血第7天）基底动脉的外膜中外源基因表达消失；注入腺病毒载体后2～4天，外源基因可以有效转移至颅底软脑膜细胞，小血管外膜和平滑肌层也可见外源基因的表达，表明蛛网膜下腔内的血凝块不能阻止腺病毒载体介导外源基因转移至颅内血管。

Viral vector mainly contain adenovirus, retrovirus,adeno-associated virus and so on, but it has potential danger of safety; it isrepeled by immune system when it is injected to organism for a greatimmunogenicity. An injection with adenovirus vector with highconcentration, it leads to serious inflammatory reaction of liver. Viralvector such as liposome and polycation are commonly used lately. But,liposome and polycation have low specificness and targetness of genetransfer tissue, have lower transfection efficiency and short period ofgene expression, for they can be phagocytized by endothelial system.
许多的载体，病毒载体和非病毒载体以前已广泛应用，病毒载体主要包括腺病毒，逆转录病毒，腺相关病毒等；但病毒载体在安全性方面存在潜在的危险；免疫原性比较强，注射到机体后很快会被机体的免疫系统排斥，当静脉注射高浓度的腺病毒载体会使肝脏发生严重的炎症反应；非病毒载体目前常用的有脂质体及多聚阳离子聚合物；但脂质体和阳离子聚合物介导基因转移缺乏组织的特异性和靶向性，转染效率较低且易被网状内皮系统吞噬，基因表达时间短；因此研制新型的非病毒载体已成为研究的热点，纳米颗粒具有小尺寸效应，表面效应，随着颗粒直径变小，比表面积将会显著增大，故具有很高的化学活性，因而纳米成为了最有应用前景的非病毒载体。
