  In this work, we first derive the corrections to the instanton configuration
of the flavored gauge field in the D4-D8 model with generic flavor numbers.
Then, as the instanton configuration on the D8-branes represents equivalently
baryon in this model, keeping our corrections in hand, we systemically study
the spectrum of baryon, heavy-light baryon or heavy-light meson and find it is
possible to fit the experimental data with the meson data in this model.
Besides, we briefly outline how to include the interaction of glueball and
heavy-light meson or baryon with our corrections, evaluate numerically the
decay rate of the heavy-light meson or baryonic matter involving glueball.
Since it is possible to fit all the spectra with same choice of the parameters
to the experimental data, we believe our corrections improve the framework of
D4-D8 model and the corrected instanton configuration is also useful to
investigate other properties of baryon in holography.
