抽取

METHODS: Bone marrow was sterilely separated from human. After heparinization, human BMSCs were harvested using density gradient centrifugation and adherence method. At the fifth passage, BMSCs at 1×108/L were incubated in the 6-well plate and divided into 2 groups. BMSCs in the edaravone group were 50% confluent and incubated in L-DMEM containing basic fibroblast growth factor and fetal bovine serum for 24 hours. After washing in PBS, these BMSCs were incubated in serum-free L-DMEM containing 20 mg/L edaravone for 24 hours. BMSCs in the blank control group were incubated in L-DMEM, supplemented with 10% fetal bovine serum.

Lastly, specimens contain HPV16 DNA were digested with restricted enyzme BamHI, and done with southern transprint to hybridize with digoxigenin-labeled probe of HPV16 genome through nuclear acid hybridization. Results (1)Among 60 cervial carcinoma specimens,the HPV16 E5 positive rate is 33%(20/60) by PCR, 70%(42/60)、58%（35/60）by nuclear acid dot hybridization with HPV16 E5 probe and HPV16 probe .

结果（1）PCR法 60例宫颈癌组织中HPV16 E5 片段的阳性率为33%（20/60）；（2）斑点杂交法60例宫颈癌组织中HPV16 E5阳性率为70%(42/60)，HPV16阳性率为58%（35/60）；（3）宫颈癌组织中HPV16 E5基因的突变率为40%（8/20），迁移位置不甚一致，随机抽取一例E5变异的PCR阳性产物进行测序分析，结果发现在E5片段中有2处变异， nt3979A→C颠换，nt3988T→C转换，导致E5编码区出现1个氨基酸的有义变异。
