Objective\ To study the influence of long-term quality of life in MHD patient after their family numbers have received home-nursing education Methods 49 cases of MHD were divided into two groups randomly: the observe groups(n=24),and the control groups(n=25).Both groups were received routing treatment with health education,while the family members of observation groups were also guided with home-nursing education.After one and five years′ treatment,the index of quality of life were compared with SF-36 respectively. Results The quality of life in observation groups was significant higher than that of control group(after one year P

Objective:To investigate the effects of Rad50-targeted inhibition on the radiosensitivity of head and neck squamous cell carcinoma cells.Methods:Rad50 in Tca8113 and OSCC-15 cells was down-regulated by siRNA.Then the cells were treated by a small dose of radiation(2 Gy),Western blot was used to detect the expression of Rad50 protein.Comet assay was used to evaluate the DNA double strand breaks(DSBs).Colony survival assay was performed to detect the survival rate of the cells.Telomere FISH was performed to assess the telomere length in the cells.Results:Target siRNA inhibited Rad50 protein expression in Tca8113 and OSCC-15 cells. siRNA combined with the radiation of 2 Gy produced more DSBs,decreased the proliferation and shortened the nucleus telomere length of the cells more than radiation treatment alone.Conclusion:The targeted inhibition of Rad50 may increase the radiosensitivity of Tca8113 and OSCC-15 cells.
