pp-bar mass threshold enhancement is studied using the data samples of J/{psi} and {psi}' collected with BESIII detector in 2009. The enhancement is evident in J/{psi} radiative decay, which is consistent with BESII result. No significant narrow enhancement is observed in {psi}' radiative decay. The study of J/{psi}{yields}{gamma}{pi}{sup +{pi}-{eta}}' is also presented, it is also consistent with BESII result, which shows that the X(1835) is confirmed at BESIII.
