【目的】探讨口腔鳞状细胞癌（OSCC）分化程度与Tip60（KAT5）表达相关性。【方法】选取口腔鳞状细胞共49例及癌旁正常口腔组织36例，采用免疫组化方法检测Tip60（KAT5）的表达状态。体外培养口腔鳞状细胞癌Cal27及UM1细胞株，Tip60（KAT5）抑制剂Nu9056处理Cal27及UM1细胞株后，MTT比色法检测Nu9056对Cal27及UM1细胞株增殖的影响。【结果】口腔鳞状细胞癌中Tip60（KAT5）的表达均明显高于癌旁正常组织中的表达（P=0.000）；随着组织学分化程度的降低，Tip60（KAT5）的表达增高，且其表达与组织学分化程度的降低呈明显正相关（r=0.461，P=0.001）；随着浓度及时间的增加，Nu9056对Cal27及UM1细胞株的增殖抑制率逐渐增加，呈浓度及时间依赖关系（P

The traditional data deletion method is easily affected by a large number of approximate features in the cloud storage environment, resulting in redundant data, resulting in too long encryption and decryption time and low key availability. This paper proposed a feature iteration-based deterministic deletion method for cloud storage data. Firstly, it extracted the redundant data characteristics in cloud storage data, and classified the redundant data under cloud storage, iterated until convergence, and the realized high performance deletion of redundant data. Secondly, it used the encryption mechanism to realize the secure sharing of cloud storage data among network users. The original data ciphertext divided into residual ciphertext and sampled ciphertext. Finally, it uploaded the incomplete remaining data ciphertext to the cloud, at the same time, introduced a trusted third party to save the sampled ciphertext, realized deterministic deletion of data by destroying sampled ciphertext. The experimental results show that the proposed method takes a short time to split data ciphertext and has a high key availability of 90%, indicating that it can effectively meet the requirement of deterministic deletion of redundant data or expire data in cloud storage systems.

Objective: Using gene chip technology to study the differences ofhepatitis B virus(HBV) drug resistance gene between Han and Uygur patients in Ili Prefecture. Methods: Selected 50 cases of Han patients and 50 cases of Uygur patients who with chronic HBV infection treated in our hospital from January 2014 to December 2015, they were diagnosed with natural HBV drug resistance gene (anti Nucleotide drugs)by gene chip technology, then observed the characteristics of HBV drug resistance genotypes, and the status of drug resistant mutations sites to Nucleotide drugs. Results: The HBV drug resistance genotypes of Han patients were focus on B-type and C-type, and the C-type was the predominant genotype, while D-type was the most genotype in Uygur patients, the differences of each genotype in two groups was statistically significant (P<0.05). Han patients was mutated significantly at rt204 site, while the Uighur patients was mutated significantly at rtn236t and rta181v/t+rtn236t sites. Conclusion: The HBV drug resistance genotypes and mutations sites are significantly different between Han and Uygur patients with natural HBV drug resistance gene in Ili Prefecture of Xinjiang,we can screen the the mutation targets through the gene chip technology and select the appropriate sensitive drug.
