Abstract

The invention belongs to the field of traditional Chinese medicine, and discloses a Chinese medicinal composition for reversing multi-drug resistance of tumor and a preparation method and an application thereof. The Chinese medicinal composition is made of the following Chinese medicinal herb raw materials by weight part: 10 to 30 parts of subprostrate sophora, 10 to 30 parts of climbing nightshade, 10 to 30 parts of broadleaf holly leaves, 10 to 30 parts of Cacumen Biotae and 10 to 30 parts of Bougainvillea spectabilis Willd.; the above Chinese medicinal raw materials are immersed in the water for 2 to 3 hours after being mixed, decocted liquid is poured out after the raw materials are heated and decocted, then water is added into the raw materials to be decocted, the decocted liquid is poured out, the decocted liquid is filtered after being mixed, the obtained clear liquid is concentrated, atomized, dried and screened after being pulverized to obtain the Chinese medicinal composition for reversing the multi-drug resistance of tumor. Blood serum of the Chinese medicinal composition is combined with adriamycin to use, 50% inhibitory concentration of adriamycin on leukemia cell adriamycin persister is remarkably reduced, the reversing times are 2.87 to 4.37 and is positively correlated to the concentration, and a remarkable effect on reversing the multi-drug resistance of tumor can be realized.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicine, and relates to a traditional Chinese medicine composition for reversing tumor multidrug resistance, a preparation method and application thereof. technical background [0002] Multidrug resistance (MDR) of tumor cells to anticancer drugs is a common factor leading to the failure of tumor chemotherapy. At present, the prevalence of cancer in China is on the rise, and the death of 90% of cancer patients is affected by the drug resistance of tumor cells to varying degrees. Therefore, it is necessary to develop a new generation of drug resistance reversal agents. It is known that some traditional Chinese medicines have calcium antagonistic effects, and the drug effects are relatively mild, and can improve the effect of chemotherapy in reversing MDR, so they have good application and development prospects. [0003] The results of the study showed that a variety of mechanisms are involved i...
