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.Radiographic Contrast-Induced Nephropathy in 6 Children
Journal of Applied Clinical Pediatrics 2006;0(17):-
Objective To investigate the clinical characteristics of radiographic contrast-induced nephropathy(RCIN) in children for improving the knowledge of this disease.Method The clinical data of 6 hospitalized children with RCIN collected from Oct.1998 to Dec.2007 were evaluated retrospectively.Results Of 92 patients who had cardio-angiography,intravenous pyelography,renal arteriography,cerebral angiography,and CT with contrast medium,6 cases(2 girls and 4 boys,aged 2-17 years old) had RCIN.Among the 6 children,5 cases [serum creatinine(Scr) was from 168.3 to 249.7 ?mol/L] showed non-oliguria-type acute renal failure;1 case(Scr was 583.1 ?mol/L) showed oliguria-type acute renal failure,and renal biopsy pathology findings showed that renal tubular epithelial cells were vacuolar degene-ration,striated border fell off,renal tubular epithelial cells were necrotic mulifocally,while the glomeruli were normal.Hematuria in 2 cases with primary disease aggravated;2 cases showed microscopic hematuria;1 case had proteinuria(+),1 case appeared microscopic hematuria and proteinuria(+).Five patients with non-oliguria-type acute renal failure were cured successfully after the medication of 10-21 days.Another case with oliguria-type acute renal failure was well after interrupted hematodialysis for 13 days and medication.Conclusion Children suffering RCIN usually manifest non-oliguria-type acute renal failure,and most of them can be cured by hematodialysis and medication mostly.
