In this article, we construct both theaxialvector-diquark-axialvector-diquark-antiquark type andaxialvector-diquark-scalar-diquark-antiquark type interpolating currents, thencalculate the contributions of the vacuum condensates up to dimension-10 in theoperator product expansion, and study the masses and pole residues of the$J^P={\frac{1}{2}}^\pm$ hidden-charm pentaquark states with the QCD sum rulesin a systematic way. In calculations, we use the formula$\mu=\sqrt{M^2_{P}-(2{\mathbb{M}}_c)^2}$ to determine the energy scales of theQCD spectral densities. We take into account the $SU(3)$ breaking effects ofthe light quarks, and obtain the masses of the hidden charm pentaquark stateswith the strangeness $S=0,\,-1,\,-2,\,-3$, which can be confronted with theexperimental data in the future.
