A neoplasm that is composed of dysplastic cells and there is no morphologic evidence of infiltration of the surrounding tissues.

Immunogenic composition for immune system modulation and use thereof, method for treating and preventing diseases, method for inducing cell regeneration and method for restoring immune response

The present invention relates to immunogenic compositions for modulating the immune system, comprising a therapeutically effective quantity of two or more immuno-active antigenic agents with pathogen-associated molecular patterns (PAMPs) and/or danger-associated molecular patterns (DAMPs) and one or more physiologically acceptable carriers, excipients, diluents or solvents. The immunogenic compositions according to the present invention are used for producing medicaments for preventing and/or treating, and for preventing and/or treating infectious diseases, auto-immune diseases, allergic diseases, inflammation, arthritis, inflammatory diseases, transplant rejection, affections caused by vascular disorders, diseases caused by haemorrhagic or ischaemic cardiovascular accidents, ischaemia, heart attack and haemorrhagia leading to tissue destruction, heart, kidney, respiratory or liver insufficiency, cancer, malign and benign tumours and neoplasia. The present invention further relates to methods for inducing the regeneration of cells, tissues, organs and organic systems such as the circulatory, nervous and endocrine systems. Finally, the present invention relates to methods for restoring immune response in an animal, in particular a human being.

Microparticle with double function of radiotheraphy and thermotherapy and preparation method thereof

The invention discloses particulates with double functions of internal radiotherapy and thermal therapy, and a preparation method thereof. The particulates are mainly compounded and formed by glass containing radioactive species yttrium-90 or / and phosphorus-32, and solid ferrite with magnetocaloric effect. When the particulates intervene in vivo, the radioactive species yttrium-90 or / and the phosphorus-32 contained in the glass can release Beta rays in vivo to kill cancer cells intervening in surrounding tissues without damaging the distant healthy tissues; the solid ferrite has good hysteresis exothermicity and can transform exosomatic magnetic energy into heat energy so as to release heat under the action of an external alternating magnetic field, so that the temperature around the tumor area can raise to 43 to 47 DEG C within a short time, and tumour cells intervening in the surrounding tissues are burnt and killed without influencing normal cells with better heat tolerance, thereby realizing the purpose of treating tumor by combining the internal radiotherapy and the thermotherapy, and having double lethality to cancer cells. The method for combining the radiation treatment and the heat treatment is an indispensable supplementary therapy means to treat the malignant tumor with chemical drug resistance. In addition, the particulates have good chemical stability and biocompatibility, and have great application prospect in the aspect of treating the malignant tumor.

Novel prodrugs von 6-hydroxy-2,3-dihydro-1h-indoles, 5-hydroxy-1,2-dihydro-3h-pyrrolo[3,2-e]indoles and 5-hydroxy-1,2-dihydro-3h-benzo(e)indoles as well as of 6-hydroxy-1,2,3,4-tetrahydro-benzo[f]quinoline derivatives for use in selective cancer therapy

The chemotherapy of malignant tumours is greatly restricted by the generally slight differentiation of the available cytostatic agents between normal and malignant tissue. In order to achieve an improvement of the selectivity in cancer therapy, novel prodrugs have been developed from 6-hydroxy-2,3-dihydro-1H-indolene, 5-hydroxy-1,2-dihydro-3H-pyrrolo[3,2-e]indolene and 5-hydroxy-1,2-dihydro-3H-benzo[e]indolene as well as from 6-hydroxy-1,2,3,4-tetrahydro-benzo[f]-quinolines, that may be used within the framework of the ADEP therapy (antibody directed enzyme prodrug therapy). The new prodrugs are characterised by a high difference in toxicity between the prodrug and underlying drug and by a very high efficacy of the drug. The high selectivity of the new prodrugs is probably attributed to the fact that, in the new prodrugs, a secondary halide is present in contrast to the prodrugs of a similar type previously produced by us. The direct alkylation of the DNA or RNA by the prodrugs and thus the toxicity of the prodrugs is thereby reduced. After splitting off of the glycosidic and / or acetal group on the phenolic hydroxy groups of the prodrugs, a spirocyclopropacyclohexadiene is formed which, being a highly toxic group, effects an alkylation of the DNA or RNA.

Tumor homing cell-penetrating peptide tLyP-1 modified apoferritin nano-cage and preparation method thereof

The invention discloses a tumor homing cell-penetrating peptide tLyP-1 modified apoferritin nano-cage and a preparation method thereof. The protein nano-cage is hollow cage-shaped protein formed by self-assembling 24 protein subunits; and one tumor homing cell-penetrating peptide tLyP-1 is modified on an N end of each protein subunit by utilizing a gene recombination technology to obtain a recombinant human body heavy-chain ferritin nano-cage with a tLyP-1 modified surface. According to the protein nano-cage provided by the invention, a medicine is loaded into the nano-cage through adjusting depolymerization and recombination of the protein subunits; the nano-cage has good water solubility and biocompatibility, has excellent stability in a human body and has a uniform size; the nano-cage can be specifically combined with a lot of neuropilin receptors 1 (NRP-1) which are expressed in tumor neovascularization and tumor cells of malignant tumors including gliomas, breast cancer, pancreatic cancer, gastric cancer, colorectal cancer, non-small cell lung cancer and the like; and types of the tumors treated by the nano-cage are greatly increased and the targeting ability of tumor treatment is improved. The protein nano-cage provided by the invention has an extremely great application prospect in the aspects of tumor diagnosis and treatment and the like.
