Leaves are bright yellow (151A~144A, Royal Horticultural Society Color Chart) during the spring and summer and yellowish green (144B~143A) in fall. However, the leaves from other members of its species are always deep green (137A~B) throughout the growth season.
Methods: Thirty-one patients with stage ⅢB~Ⅳ lung adenocarcinoma ,pathologically proved were given 1~3 month treatment of Iressa. The serum levels of TPS,CEA,Cyfra21-1 and NSE before and after therapy were measured by ELISA method.
Forty cases with stage Ⅲb~Ⅳ NSCLC pathologically proved w ere enrolled in this study. Oral ZD1839 250mg daily were given to patients with r efractory advanced NSCLC until severe toxicity or disease or progress occurred.
In principle, longer collecting plates would have more advantages for the increase of collection efficiency of the two types of EACs, but the simulation results show that it is sufficient for single-stage cleaner with the critical length of 12b~14b and for double-stage cleaner with the critical length of 10b from the point of view of economical consideration.
And using two yieding point of the velocity function,the increasing or growth process of Logistic curve was divided into gradually growth period (t=0～(lna-1.317)/b)、fast growth period(t=(lna-1.317)/b～(lna+1.317)/b)、solw growth period(t=(lna+1.317)/b)～∞).
