Technical field
The present invention relates to a kind of leukemic Chinese medicine composition and preparation method thereof that is used for the treatment of, belong to the field of Chinese medicines.
Background technology
Leukemia is the malignant disease of hemopoietic tissue.Be characterized in that unrestrictedly hypertrophy of a large amount of leukaemias is arranged in bone marrow and other hemopoietic tissue, and enter peripheral blood, and the manufacturing of normal plasma cell is obviously suppressed, this disease occupies the first place in the youngster malignant disease, the cause of disease still imperfectly understands so far, virus may be main virulence factor, may be morbific cofactor but also have many factors as radiation, chemical toxicant (benzene etc.) or medicine, heredodiathesis etc.According to jejune degree of leukaemia and leukemic natural history, be divided into acute and chronic two big classes.According to the proliferative cell type, can be divided into granulocytic, lymphatic and monocarpotic cellularity three classes.Mainly show as infection, heating, anemia and hemorrhage.
Main treatment has following a few class chemotherapy, radiotherapy, target therapy.Part high risk patient need carry out bone marrow transplantation.Over nearly 10 years, along with the progress of molecular biology, biogenetics, more deep to leukemic cause of disease epilepsy reason understanding, new therapy, the discovery of novel drugs and the use of Chinese medicine are taken on a new look leukemic prognosis greatly simultaneously.
Chinese medicine does not have " leukemia " this name of disease, according to its clinical manifestation such as heating, anemia, hemorrhage, liver spleen and lymphadenectasis etc., be attributable to the traditional Chinese medical science " asthenia ", category such as " acute pulmonary tuberculosis ", " hot labor ", " blood disorder ", " sucutaneous nodule ".Though do not have unified dialectical foundation, the general trend of traditional Chinese medical science leukemia differentiation of symptoms and signs for classification of syndrome is still based on type of deficiency of both QI and YIN, QIXUELIANGXU type, pyretic toxicity stagnation type and blood stasis accumulation type.
The inventor thinks that the leukemic cause of disease is caused by " malicious heresy is gone into blood ", and this evil poison enters versatile thermal burn the moon behind the body, thereby again this malicious heresy is called burning hot heresy, also is referred to as fire-toxin, pyretic toxicity.In addition, evil poison also should comprise the endogenous toxin due to the internal injury.The internal organs meridians of evil poison invasion human body under certain endogenous cause of ill condition, from outward appearance to inner essence, or poison is from interior and give birth to, inside and outside close poison.Evil poison accumulates and amasss in interior with the passing of time heat-transformation.So the rule of treatment is worked as based on heat-clearing and toxic substances removing.
