In this article, we construct the six-quark currents with the , , and to study the dibaryon and baryonium states via QCD sum rules. We consider the vacuum condensates up to dimension 16 and truncation of the order with . The predicted masses are GeV, GeV, GeV GeV for the , , and states, respectively, which can be confronted to the experimental data in the future considering the high integrated luminosity at the center-of-mass energy about at the BESIII. We find the terms with do play a tiny role, and we can ignore these terms safely in the QCD sum rules.
