In this paper, we study the notions (strongly) soc-injective, (strongly) simple-injective and (strongly) mininjective modules in sigma [M]. For any module N in sigma[M], N is strongly mininjective in sigma[M] if and only if it is strongly simple-injective in sigma[M]. A module M is locally Noetherian if and only if every strongly simple-injective module in sigma[M] is strongly soc-injective. We also characterize Noetherian QF-modules.
