In this paper, we study the upper bounds on the mass insertion parameters (δ^q_AB)_ij in the minimal supersymmetric standard model. We found that the information from the measured branching ratio of B→X_sl⁺l^- decay can help us to improve the upper bounds on the mass insertions parameters (δ_AB^u,d)_3j,i3. Some regions allowed by the data of Br(B→X_sγ) are excluded by the requirement of an SM-like C_7γ(m_b) imposed by the data of Br(B→X_sl⁺l^-).
