The invention discloses a treatment
medicine capable of degrading high-
polymer tumor and a sustained-release
medicine for
normal cell protective agent. The sustained-release
medicine comprises one or more of the following sustained-release systems: (1) a
tumor tissue and
peripheral implanted medicine sustained-release
system; (2) an absorbable nanometer medicine sustained-release
system containing a lymphaden tracking medicine in
lymph; (3) a nanometer medicine sustained-release
system in blood or
body fluid; (4) a nanometer medicine sustained-release system in a specific tissue, wherein, the specific tissue can be a liver, a
spleen, a
lung or marrow. The treatment medicine for tumor comprises one or more of chemotherapeutic medicine, chemotherapeutic sensitizer and
tumor targeting medicine, and uses
amifostine as the
normal cell protective agent. The range of tumor treatment is applicable to any tumor through changing different treatment medicines. The invention is a novel medicine application platform, can be used by any new medicine besides the existing medicines, and plays a role in conquering
