Based on the closed time path formalism, a deduced Feynman rule for directly calculating the retarded and advanced Green functions is given. This Feynman rule is used to calculate the two-point self-energy and three-point vertex correction in φ3 theory. The generalized fluctuation-dissipation theorem for three-point nonlinear response function is verified.
