Objective To observe the effects of Bushen Huoxue Formula on free radical metabolism and p16 protein expression in heart of aged rats; To discuss its protective mechanism to the heart of aged rats.Methods One hundred were divided into young control group, the natural aging group,Bushen HuoxueFormula high-, medium- and low-dose groups, with 20 rats in each group. Each medication group was given relevant medicine for gavage, once a day for 16 weeks. 1 hour after the last administration, after the rats were sacrificed, serum and heart were taken. The contents of NO and MDA and activities of CAT and SOD in serum and myocardial,β-galactosidase enzyme and p16 protein expression in myocardial tissue were detected.ResultsCompared with the natural aging group, NO content and SOD activity in the serum of rats inBushen Huoxue Formula high-dose group increased significantly (P<0.05) and MDA content in allBushen Huoxue Formula groups decreased (P<0.01); NO content, CAT and SOD activity in the myocardial tissue of rats inBushen HuoxueFormula high-dose group increased significantly, and MDA content decreased significantly (P<0.05). CAT activity in allBushen HuoxueFormula groups increased (P<0.05,P<0.01).β-galactosidase enzyme and p16 protein expression in myocardial tissue in allBushen Huoxue Formula groups decreased.Conclusion Bushen Huoxue Formula can in hibit the aging of myocardial-aged rats, and the mechanism might be related to its anti-oxidative damage and inhibition of tumor suppressor gene p16 expression.

Objective To observe the clinical curative effect of Q-switch Nd YAG laser on the treatment of facial hormone-dependent dermatitis. Methods Attal of 120 patients were randomly divided into two groups. The control group was orally administered antihistaminic drugs and Vitamin B6. Based on drugs applied to the control group, additional Q-switch NdYAG laser radiation therapy was introduced into the treatment group. Results After the treatment,pru-ritus and total scores of skin lesion in the treatment group were less than the control group. A total effective rate of 86.67 % was achieved in the treatment group, while that was 66.67 % in the control group. The difference between the two groups was statistical significant(P<0.05). Conclusion The treatment of facial hormone-dependent dermatitis with large light-spot and low-energy Q-switch Nd YAG laser 1064 nm radiation therapy is safe and effective. There-fore,it is well worth popularizing and trying.
