Some Recent Topics on Possible Chiral Restoration in Nuclear Medium

Some topics are introduced on possible evidences of chiral restoration in nuclei and related ones. The topics include the $\sigma$-mesonic mode in nuclei, the vector mesons in a nuclear matter, deeply bound pionic and Kaonic nuclei with a discussion on the nature of $\mathrm{\Lambda }(1405)$. Other related topics are briefly mentioned. An emphasis is put on that phenomena even in finite nuclei with normal and sub-normal nuclear density, as will be explored in the new project in GSI and possibly in J-PARC, are interesting for physics of finite-density QCD.
