RESUMEN
Objective To study expression of p27 and cyclin D 1 proteins and their significance in non-Hodgkin's lymphoma (NHL).Methods The expression of p27 and cyclin D 1 proteins were detected by imunohistochemical technique in 77 cases of NHL.Results Of 77 NHLs, the positive rates of p27 and cyclin D 1 protein were 51 9% (40/77) and 58 4% (45/77) respectively, and the positive intensity of p27 in low grade group was significantly higher than in high grade group (P

RESUMEN
To study the relationship between the different pulse conditions and photoplethymograms, the photoplethysmogram of 432 subjects, including normal pulse condition and 10 commonly - seen abnormal pulse, was examined at Cun - kou area with a BC - 4 quantitative photoplethysmograph. Meanwhile hemodynamic parameters were analysed. As compared with the normal pulse, photoplethysmograms of different pathological pulse conditions at Cun - kou area showed their specifical parameters and the changes of hemodynamic parameters reflected features of cardiovascular pathophysiology formed by different pulse conditions. It suggests that photoplethysmograms at the Cun -kou area can supply objective basis for clinical diagnosis of different pulse conditions.
