%X We study whether the broad enhancement X（1576） arises from the final state interaction （FSI） of p（1450, 1700）→p^＋ p^- →K^＋ K^-decay,Both the absorptive and dispersive contributions of the above amplitudes are considered since the intermediate states are very close to p（1450, 1700）. AThe same mechanism leads to a similar enhancement around 1580 MeV in the π^＋ π^- specturm in the J/ψ →π^0 π^＋ π^- channel, which can be used to test whether X（1576） can be ascribed to the FSI effect ofp（1450, 1700） → p^＋ p^-.
