I correct myself: what I want exactly is:

\item{bla} bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla
\item{bla} bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla
\item{bla} bla bla bla bla bla bla bla bla bla bla bla bla bla
                                       <a centered text>
\item{bla} bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla
\item{bla} bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla
