Our results demonstrate: The structures of the organs are normal, and the shapes of cells are clearly visible. There are lots of positive brown granules in Chief cells and Parietal cells in abomasum as well as the mucosa epithelial cells and gland cells of duodenum. Three bands with a molecular mass close to 120KDa、110KD and 98KDa were identified by Western Blot. The Ob-R levels of 120KDa in abomasum were significantly higher than that of in small intestine. The levels of 110KDa were similar in the two organs. The expression of 98KDa Ob-R was weak.

HE染色结果显示，各组织结构正常，细胞形态清晰可见；免疫组织化学SABC染色显示，在皱胃胃体部固有层胃底腺的主细胞和壁细胞及十二指肠黏膜上皮细胞和固有层肠腺的柱状细胞中均可见大小数量不等的棕黄色颗粒；western Blot 实验发现，在胃和小肠均检测到120KDa、110KDa和98KDa三条带。120KDa长型瘦素受体蛋白在胃中表达量显著高于小肠中的表达；110KDa的短型瘦素受体蛋白，在小肠和皱胃中表达量接近。98KDa短型受体蛋白在胃和小肠表达均较弱。

Results Compared with that in the NP tissues, the number of α-SMA positive cells increased significantly in BPH tissue, and the number of vimentin positive cells increased moderately in the stroma and prominently surrounding the acinus and in the basal layer. In BPH tissue, the myosin and ERα staining signal was lost in the stromal cells surrounding the acinus, and the positive staining cells gathered into bunches in the stroma far away from the acinus, while the positive cells were sporadically distributed in the NP tissue. The PCNA positive cells increased moderately in the stroma and increased significantly in the basal layer.

结果 与NP相比在BPH中，α-SMA阳性染色细胞显著增加；波形蛋白在间质中阳性染色细胞有所增加，在腺泡基底层及临近腺泡外层间质中阳性染色细胞明显增加；在临近腺泡外的数层间质细胞中肌球蛋白和ERα由部分阳性变为完全阴性染色，而在远离腺泡的间质中其阳性染色细胞由散在斑块状分布变为簇状密集排列；PCNA在间质中阳性染色细胞有所增加，在基底细胞层中阳性染色细胞显著增加。

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.

然后，通过与ONYX-015（E1B 55 KD a蛋白缺失的2型和5型嵌和型腺病毒，美国ONYX生化制药公司研制）、wtAd5进行对比，利用病毒增殖实验和细胞生长抑制实验，验证了CNHK500选择性增殖能力和肿瘤特异性杀伤作用；利用Western Blot检测CNHK500腺病毒E1A和E1B在乳腺癌细胞和正常成纤维细胞中的表达差异，揭示了腺病毒肿瘤靶向性的机制；利用携带绿色荧光蛋白的CNHK500-EGFP感染乳腺癌细胞株和正常成纤维细胞株，直观地观察其感染乳腺癌细胞的能力和在乳腺癌细胞中的增殖过程。

Methods In this study,a plasmid vector,rAd5,and rAAV2 were used to transfect rat cochlear marginal cells of stria vascularis by injection into the perilymph through the round window membrane,and the transfection efficiency, target tissue accessibility, cell/ tissue toxicity, time course of expression, and effect on hearing were evaluated in vivo and in vitro.

结果三种载体对原代培养的大鼠耳边缘细胞的转染研究发现，腺病毒的转染效率最高，而腺相关病毒转染对细胞活性影响最小。rAAV2和rAd5对大鼠耳蜗组织的感染实验发现，腺病毒和腺相关病毒携带的增强型绿色荧光蛋白可在多种耳蜗组织中及转染对侧耳蜗组织表达，且并不引起明显的耳蜗组织细胞凋亡。rAAV2携带的EGFP基因在第90天时仍可检测到大量表达。rAd5携带的EGFP基因在第30天时表达明显减弱。

The MIP-1β mRNA expression in squama cell cancer and adenocarcinoma were significant higher than which in bronchus-alveolus cell cancer without significant difference between each other.

在肺鳞癌和腺癌的大多数癌细胞胞浆中有MIP-1β蛋白表达，在支气管肺泡细胞癌无明显表达；MIP-1β蛋白表达阳性率在腺癌和鳞癌无显著差异（69.7%比58.6%）。

Results:In the endometrial carcinoma tela,the lack of expression of protein pten existed in endometrioid adenocarcinoma mainly,which accounted for 60 per cent.
