Results:(1) The rats produced amphetamine CPP after treated with 2 mgkg^(-1) amphetamine for 4 days. Ketamine and low, middle, high dose rhynchophylline all could eliminate the CPP effect, and the effect of rhychophylline was increased in a dose-dependent manner. Rhychophylline itself could not induce CPP in normal rats.(2) When compared with normal rats, the NR2B expression in nucleus accubens and amygdaloid of the model rats was obviously increased. Ketamine and middle, high dose rhynchophylline could decrease NR2B expression induced by amphetamine, while low dose rhynchophylline did not affect NR2B expression. Rhynchophylline had no effect on RN2B expression in normal rats.

Secondly, by applying inverse Fourier integral transform to the displacement, and uniting the constitutive and geometrical equations, the analytical expression of stress in Laplace domain were derived. Thirdly, by defining dislocation density functions, the Cauchy singular integral equations were obtained according to the boundary condition and interface connection conditions, and the problem was reduced to algebraic equations by Chebyshev orthogonal polynomial.
