Some essential trace elements were reported to be involved in the normal bone metabolism. Nowadays rare earth elements are widely used in many fields and more and more rare earth elements enter the environment and food chains They are enriched in bone and difficult to be excreted. Because the similarity between rare earth ions (Ln3+) and Ca2+, they will intervene and regulate bone formation and remodeling.

骨骼的正常代谢涉及多种金属离子，随着稀土的应用，通过环境和经由食物链等渠道进入人体内的稀土量也有所增加，并且在骨组织中相对富集且难排出；由于稀土与钙离子的相似性，它们将干预和调控骨的形成与再造。

It is proved that every Lie derivation of nest algebra is the sum of an associative derivation and a general trace. Every Lie isomorphism between nest subalgebras of a factor von Neumann algebra is the sum of an isomorphism and a general trace or the sum of a negative anti-isomorphism and a general trace. Lie invariant subspace of linear mappings on Banach algebras is introduced, and linear maps from nest subalgebra of a factor von Neumann algebra into itself which satisfy the property that the space of derivations is their Lie invariant subspaces are characterized. Simultaneously, it is shown that such maps are Lie derivations modulo the set of scalar multiple of the identity.
