9.Epigenetic regulation and gastric cancer
Journal of International Oncology 2012;39(4):292-295
The initiation and development of gastric cancer is due to the effects from both external and internal factors.Recent researches show that external environment factors regulate and control the key genes expression during the process of cell's growth and development through epigenetic modification such as DNA methylation or demethylation,histone modification and small RNA,thus playing an important role in gastric cancer's occurrence and development.
10.Influence of thymus transplantation on T cell subsets of peripheral blood in patients with allergic rhinitis
Chinese Journal of Organ Transplantation 1998;19(3):177-179
Cultured human embryonal thymus graft was performed on 80 patients with allergic rhinitis to observe the immune function of the patients and the treatment efficiency. The thymus from the fetus of intermediate abortion was cultured for 7 to 10 days. The T cell subsets and serum antigen special IgE(sas IgE) level of the patients were determined before and after the thymus transplantation. The gross treatment efficiency is up to 92.4% among the trial patients after graft for 3 years and CD8 positive cells were increased with a significantly statistical difference (P<0.01), and sas IgE level was much lower than before thymus transplantation (P<0.01). It was concluded that the thymus transplantation might regulate the immune function of the patients with allergic rhinitis, including increases in the number and the function of Ts cells, and a decrease of IgE level.
