1.The refitting equation was then tested and compared with the other equation in the validation sample. Results (1)Both the MDRD and CG-GFR prediction equations seemd to systematically underestimate GFR,but the accurancy of MDRD equation was better than CG-GFR in stage Ⅰ~Ⅲ of CKD.
2.Conclusion [WT5”BZ]The increase of maternal CG, TBIL, DBIL, ALT, AST of women with ICP are related to the morphologic changes of the placenta.
3.Methods：1. The concentration of serum CG, TBIL, DBIL, ALT, AST were measured half an hour before cesarean section in 60 cases of ICP and 25 cases of normal pregnant women.
4.(2)The bias of estimated GFR(MDRD or CG-GFR equation)with ~ 99m Tc-GFR was lower in stage Ⅰ~Ⅲ than in stage Ⅳ~Ⅴ of CKD.
5.(2)The levels of CG was not related with meconium staining,fetal weight,Apgar score ,S/D ratio of umbilical artery and gestational age（p>0.05）.
6.Results [WT5”BZ]Maternal CG, TBIL, DBIL, ALT, AST of women with ICP were significantly higher than healthy group, and the placenta intervillous space area density was lower.
8.A new extrapolation multigrid method in solving large scale finite elemen system of equation is proposed, i. e. new extrapolation values of finite element solutions on the first two level grids are used to provide the good initial values on the third level grids and then an exacter finite element solution can be obtained by several CG-iterations.
