In a jazz blues there are a few common variations to the typical I-IV-V blues. Most common is to play a final ii-V-I instead of the usual IV-V I (replace IV with ii). Once you've done that it is easy to lead to that ii chord with a VI chord. For example in our blues in G instead of C(IV) to D7(V) to G7(I), we will play Am7(ii) to D7(V) to G7(I). If we lead to am7 with E7 (Principle 3 "Lead to any chord with its own dominant") then we have the jazz blues turnaround.
