1.Research progresses of tumor inhibiting protein p33ING1b in the tumors of digestive system
Practical Oncology Journal 2015;(3):254-258
Tumor inhibiting protein p33ING1b is the key expressive product of inhibitor of growth 1.It plays critical role in cell multiplication ,period control ,senescence ,repair of DNA damage ,apoptosis ,and chroma-tin remodeling.The abnormal expression of p33ING1b is closely related to the occurrence and development of tumor.This paper reviews tumor inhibiting protein p 33ING1b in the research development of tumors in digestive system.

Objective:To express human interferon-?2b gene and to explore the feasibility of expressing human gene in plant cells.Methods:The hIFN-?2b coding sequence was amplified by PCR with specific primers and plasmid pBV889 was used as a template,subcloned into middle vector pMD18-T and binary vector pBI121 to obtain plant expression vector pBIFN. The pBIFN was transformed into Agrobacterium tumefaciens strain LBA4404. Then hIFN-?2b gene was introduced into Ginseng callus cells via Agrobacterium-mediated transformation. The positive cells were screened by G418. The transgenic Ginseng calli were confirmed by PCR,RT-PCR,Western blot and WISH/VSV system.Results:Stable integration of the hIFN-?2b gene in the Ginseng callus cells′ genome was confirmed by PCR analysis. RT-PCR analysis showed that there were transcription products. Western blot implied that the given protein was hIFN-?2b. WISH/VSV system assay showed that the expressed hIFN-?2b possessed relatively lower bioactivity.Conclusion:HIFN-?2b has been expressed in transgenic Ginseng calli, which facilitates further investigation of improving the curative effect of orally administered hIFN-?2b.

BACKGROUND: Establishment of lumbar disc degeneration in animal models can help doctors understand the development rules and pathophysiological changes of this disease, and can explore and research more rational treatment by creating animal models.OBJECTIVE: To review recent advances in vivo model of lumbar disc degeneration.METHODS: The first author used the computer to search related articles on PubMed database and Chinese Journal Full-text Database from inception to May 2016. The search key words were lumbar disc, degeneration, animal model,vivo model. A total of 161 related articles were retrieved and 49 of them met the inclusion criteria.RESULTS AND CONCLUSION: (1) Building an intuitive and reliable animal model of lumbar disc degeneration will not only help the basic research of degenerative disc disease, but also provide a good experimental carrier for the repair treatment of degenerative lumbar disc. (2) After more than 80 years of development, the animal model of lumbar disc degeneration has formed a production mode of more species, more methods and newer ideas. Current models have their own advantages, cannot be replaced. However, problems such as poor controllability, low degree of safety or long observation period are still exiting more or less. All these need further research and exploration.
10.Expression and clinical significance of HMGB1 and mutant p53 in cholangiocarcinoma tissues
International Journal of Surgery 2016;43(4):245-248,封3
Objective To investigate the expressions and clinical significance of HMGB1 and mutp53 in bile duct carcinoma tissue.Methods The expressions of HMGB1 and mutp53 were detected by immunohistochemistry in 47 cases cholangiocarcinoma tissue and 25 cases normal biliary duct tissue,and their correlation with clinicopathological parameters of cholangiocarcinoma was analyzed.Results The expression of HMGB1 and mutp53 was positive in 78.72% (37/47) and 63.83% (30/47) respectively of the cases with cholangiocarcinoma tissue,and 12.00% (3/25) and 4.00% (1/25)respectively of the cases in normal biliary duct tissue(all P <0.01).The expression of HMGB1 and mutp53 in cholangiocarcinoma tissue was relating to degree of tumor differentiation,lymph node metastasis,perineural invasion and TNM-staging(all P < 0.05),and no relation to age,gender,serum bilirubin level,metastasis of tumor and site of tumor(all P >0.05).The expression of HMGB1 was positively correlated with that of mutp53 in bile duct carcinoma tissue(r =0.574,P < 0.05).Conclusion The expressions of HMGB1 and mutp53 were increased in cholangiocarcinoma tissue,both of them play critical role for the occurrence,development,invasion and metastasis of cholangiocarcinoma.
