  We review various approaches to the calculation of QCD condensates and of the
nucleon characteristics in nuclear matter. We show the importance of their
self-consistent treatment. The first steps in such treatment appeared to be
very instructive. It is shown that the alleged pion condensation anyway can not
take place earlier than the restoration of the chiral symmetry. We demonstrate
how the finite density QCD sum rules for nucleons work and advocate their
possible role in providing an additional bridge between the condensate and
hadron physics.
