A kind of myelosuppressive Chinese medicine composition of caused by radiotherapy and chemotherapy and preparation method thereof that improves
Technical field
The present invention relates to Chinese medicine composition, especially a kind of myelosuppressive compound Chinese medicinal preparation of caused by radiotherapy and chemotherapy of improving.
Background technology
Under the normal condition, granulocytic aging death, destruction and discharge are relative steady state in the propagation of bone marrow inner cell, maturation and release and the peripheral blood.Some tumor has been destroyed this balance in its therapeutic process, leukopenia even pancytopenia promptly occur.Various lonizing radiation the inhibition of bone marrow is more common in the tumour radiotherapy and radiotherapy after.Lonizing radiation not only can make bone marrow depression, and can the direct killing granulocyte or cause chromosomal change, its microcirculatory change often the reasonable time in can not get recovering.The chemotherapeutics of radiotherapy sensitization effect such as DNR, ADM etc. have also increased side effect when increasing radiation sensitivity.Because bone marrow and lymphoid tissue molecular marker for increased proliferation, differentiation degree is low, extremely sensitive to lonizing radiation, so the bone marrow damage degree depends on size, range of exposures and position, the irradiation time etc. of radiological dose. the bone marrow depression of caused by radiation is light far beyond chemotherapy, mainly influence granulocyte series, large tracts of land can influence BPC.Most cancer therapy drugs all have bone marrow inhibition in various degree.Chemotherapeutics (antitumor drug) can act on the different links in cancer cell multiplication cycle, suppresses DNA division growth ability, thereby plays the tumor treatment effect.But because chemotherapeutics lacks selectivity, also can kill many normal marrow cells when killing the massive tumor cell, especially granulocyte series be had the greatest impact, thereby bone marrow depression occurs, clinical manifestation is a leukopenia, or pancytopenia.In the chemotherapy process, along with the chemotherapeutics increase of cumulant in vivo, its bone marrow depression also increases the weight of gradually.The bone marrow depression of most cancer therapy drugs comes across 1~3 week after the medication, continues to recover in 2~4 weeks.But HN2 suppresses lymphocyte, but occurs in after the administration 24 hours.It is slower that the bone marrow depression of nitrosourea occurs, and minimum saw for the 3rd~4 week, and convalescent period also was about for 6~8 weeks.Most medicines are accompanied the corresponding decline of platelet BPC to suppress WBC, minority medicine such as MMC, and CBP is to suppress BPC.
Bone marrow depression is that tumor is put, the modal side effect of chemotherapy, and based on leukopenia, erythrocyte, platelet all can have decline in various degree, and severe patient can cause infection, anemia and hemorrhage, causes treatment to be interrupted.Leukogenic effects such as conventional Western medicine such as batilol, leucogen, adenine phosphate are slow, and therapeutic effect is not obvious, and granulocyte colony-stimulating factor is difficult to conventional the application because of costing an arm and a leg.
The traditional Chinese medical science is thought, radiotherapy ray and chemotherapeutics belong to " heresy of pyretic toxicity ", in invade behind the human body easily yin-damaging and Qi consuming, decrease the smart liquid that burns, cause visceral dysfunction, have a strong impact on source of generating QI and blood, the disease that QIYINLIANGXU occurs, so put, leukopenia caused by cancer chemotherapy disease belongs to the deficiency syndrome category, its main pathogenesis and spleen kidney are in close relations, thus benefiting QI and nourishing blood, warming and recuperating the spleen and kidney, benefit bone life marrow, enriching kidney essence be alleviate put, the myelosuppressive basic rule of treatment due to the chemotherapy.By traditional Chinese medical herbal treatment, can effectively improve the leukopenia or the pancytopenia of caused by radiotherapy and chemotherapy, make tumor patient pass through therapeutic scheme smoothly.But be not that the Chinese medicine that has effects such as benefiting QI and nourishing blood, warming and recuperating the spleen and kidney, the living marrow of benefit bone, enriching kidney essence arbitrarily all can have the myelosuppressive effect of the caused by radiotherapy and chemotherapy of improvement with the arbitrary proportion combination.
