Objective To investigate the expression of NANOG gene in cervical cancer and its effect on the development of the cancer. Methods By using immunohistochemistry, NANOG expression levels were demonstrated in normal cervical tissues, cervical cancer in situ and cervical cancer tissues. Tumor sphere cells from cervical cancer tissue and their differentiated cells were injected into nude mice to observe the tumor growth. Results When compared with that of the normal cervical tissue, significantly higher NANOG protein expression level was found in cervical cancer and cervical cancer in situ (P<0.05). Tumor spheres were formed from the non-serum culture of cervical cancer tissue and the spheres could differentiate into epithelial-like cells. The sphere cells of cervical cancer caused tumor formation in nude mice. Conclusion The results suggest that cancer stem cells are present in cervical cancer and NANOG may play a crucial role in the development of cervical cancer.

Pediatric cancer is one of the leading causes of death in children around the world.Although radiotherapy is an important means of treatment for pediatric cancer,it causes acute or chronic adverse events that may affect patients' survival time and quality of life.As a novel and advanced radiation technique,proton therapy allows for precise dose delivery in target volume,significantly reducing the irradiation to surrounding tissues and organs.Studies have shown that proton therapy is well tolerated in the treatment of pediatric cancer,and it achieves good tumor control;proton therapy is superior to traditional radiotherapy in improving quality of life,protecting intelligence,and reducing the risk of secondary cancer.This article reviews the research advances in the application of proton therapy in the treatment of pediatric cancer.
10.Experimental study of chitosan on proliferation of bladder epithelial cells in vitro in rabbit ZHENG
Chinese Journal of Urology 2008;29(z1):31-34
Objective To study chitosan's improving proliferation effect to the bladder epithelial cells,thus providing experlimental foundation for the treatment of interstitial cystitis.Methods Bladder epithelial cells were harested by the enzymatic digestion of the epithelium exposed by the eversion of reseeted New-Zealand hare's bladder.The cells were cultured in different concentrations(0.3、0.6、1.2、2.4、4.8 g/L)of chitosan group and control group,after 72 h,observing their growth and proliferation with optical microscopy;The effects of chitosan on proliferation of rabbit bladder epithelial cells were studied by NAG assay.EGFR mRNA was measured by PT-PCR.Results The growth of cells in the sample added chitosan is much better than that of in the control group.Chitosan could promote the proliferation of bladder epithelial cells at higher than 0.3 g/L of concentration in a dose dependent way.The optimum concentration to increase proliferation of eonjunctival epithelial cells was 1.2 g/L.The proliferative effect of EGFR mRNA increased with the elevated chitosan concentration after 72 h.Conclusions Chitosan can promote the growth of the bladder epithelial eell,which can provides a valuable evidence for further studies of interstitial cystitis's treatment.This proliferation effect is perhaps related to chitosan's promoting EGFR combinating specificity with EGFR.
