In this talk we present the updated sin^2(2q13) value and first measurement on |dm^2_ee| based on a spectral shape analysis using 500 live days of data. And they are sin^2 (2theta_13) = 0.082 +- 0.009(stat.) +- 0.006 (syst.) and |dm^2_ee| = 2.62 +0.21 -0.23 (stat.) +0.12 -0.13(syst.) (X 10^-3 eV^2. The systematic uncertainty of sin^2(2q13) has improved mainly due to the better estimation of the Li9/He8 background and the reduction of its uncertainty. The 5 MeV excess of the electron anti-neutrino events is also discussed.
