With western blot analysis and DNA polymerase chain reaction-single strand conformation polymorphism assay,protein product of Rb gene and mutation in exon 5～8 of P_(53) gene were examined in 17 cases of human testicular seminoma.

采用Western印迹和DNA聚合酶链反应－单股构造多态性分析法对17例人睾丸精原细胞瘤组织标本的抗癌基因Rb表达的蛋白产物和P_（53）基因外显子5～8的突变进行检测，发现有3例标本的Rb基因表达的蛋白产物缺失，有4例标本的P_（53）基因有点突变，对照的正常人睾丸组织和视网膜组织均呈Rb基因蛋白产物表达阳性，对照的正常人睾丸组织中未发现P_（53）基因突变。

The CT sign of tumour of former cell of conclusion spermary sperm has opposite diagnostic sex, marriage is clinical integration analysis, have fundamental value to this ill diagnosis.

To address this question in an unbiased and genome-wide manner, we developed a new method, methylation-specific digital karyotyping, and applied it to epithelial and myoepithelial cells, stromal fibroblasts from normal breast tissue, and in situ and invasive breast carcinomas.

为了能无偏向地并在基因组范围解答这个问题，我们开发了一种新的方法——甲基化特异性数字染色体组型，并将这一方法应用于上皮细胞和肌肉上皮细胞、正常乳腺组织来源的基质成纤维原细胞、原位及侵入性乳腺癌细胞。

Therefore, collagen metabolism is the center of the extracellular matrix remodeling in intracranial saccular aneurysms, while the essence of the remodeling process is a kind of autoimmunological and inflammatory reaction.
