Objective To study the effect of integrated tradition and western medicine on unstable angina.Methods Sixty-six patients with unstable angina were randomized into two groups:control group treated only with routine therapy(n=33) and experiment group treated with routine and jia jian luang gan jian therapy(n=33).The difference of EKG,symptoms and clinic comprehensive evaluation between before treatment and after-3-week-treatment were compared.Results The rate of symptoms and ECG improvement was higher in experiment group than control group(94% vs 73%;73% vs 45%).The difference of clinic comprehensive score between before treatment and after 3 weeks treatment was significantly higher in experiment group.Conclusion The treatment of integrated tradition and western medicine on patients with unstable angina is more effective.

Objective To investigate the antioxidative effect of polypeptide from Chlamys farreri (PCF) on HaCaT cells damaged by ultraviolet B (UVB). Methods HaCaT cells model established by UVB irradiation were randomly divided into seven groups. After pretreatment with different concentrations of PCF for 1 h, the cells were irradiated by UVB at a dose of 30mJ/cm~ 2, and followed further incubatiou for 18 h. Enzyme activities including superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and catalase (CAT) were determined by biochemical methods. Total antioxidative capacity (T-AOC) and malondialdehyde (MDA) were also determined. Results PCF could enhance the activities of SOD, GSH-Px and CAT; increased T-AOC and inhibited MDA formation. Conclusion These results indicated that PCF exhibited protective effects on HaCaT cells irradiated by UVB owing to its antioxidative action.
