Clinical observation of valsartan in combination with amlodipine in therapy of essential hypertension together with the impact on red cell distribution width / 中国医师进修杂志

Objective To observe the therapeutic effectiveness of valsartan in combination with amlodipine in therapy of essential hypertension and the consequent changes in red cell distribution width (RDW).Methods One hundred and ten patients of hypertension were selected,then randomly divided into treatment group (56 cases) and control group (54 cases).Valsartan and amlodipine were given to the treatment group,while the control group taking amlodipine only.Bp and RBC were carried out before and after treatment.Results Antihypertensive effect of the treatment group were statistically significant compared with the control group (P ＜ 0.05).The consequent RBC,Hct and Hb,RDW level of treatment group decreased dramatically compared with the control group (P ＜ 0.01 or ＜ 0.05).Conclusions Valsartan in combination with amlodipine in ther apy of hypertension is a prospective combination which achieves superior blood pressure control,low level of RDW and blood viscosity,as a result reducing the incidence of cardiovascular events.

Ku proteins and tumor radiosensitivity / 国际肿瘤学杂志

Ku is a heterodimeric protein which is composed of Ku70 and Ku80.DNA dependent protein kinase is composed of Ku and DNA dependent protein kinase catalytic subunit (DNA-PKcs).DNA double strands break is the main method that radiation kill tumor cell,which will restraint DNA repair,and induce cell apoptosis.Ku protein is the key point in the repair of DNA.Blocking Ku protein will increase the radiosensitivity of tumor cell.
