Background
Primary liver cancer (primary liver cancer) is the fifth most common malignant tumor in the world, and the fourth of the causes of tumor-related death is about 84 ten thousand new cases each year, wherein hepatocellular carcinoma (HCC) is the histologic type (accounting for 75% -85%) and has the characteristics of high invasiveness and high mortality, the early liver cancer is mostly resected by surgery, but the recurrence rate of HCC is still as high as 70% in 5 years after the resection of liver cancer, most of the patients recur within 2 years after the surgery, unresectable hepatocellular carcinoma (HCC) patients usually receive the multi-kinase inhibitor sorafenib or mavatinib, however, the drug resistance and adverse reaction limit the survival benefit of the patients, in recent years, the immune therapy represented by Immune Checkpoint Inhibitors (ICIs) has been greatly progressed, while the heterogeneity of HCC biological behaviors causes only 25% of the patients to generate lasting therapeutic response, although other therapeutic modalities such as ablation therapy, transcatheter arterial embolization (TACE) also have been greatly progressed, but the survival rate of the HCC patients has been only 18% recurrences.
Sorafenib is a first-line medicine for advanced HCC, and can also treat hepatocellular carcinoma by inhibiting systemXc-to further cause GSH exhaustion to induce iron death, but only a part of liver cancer patients can benefit from the drug resistance, and as many fat-soluble active ingredients of the drugs are difficult to dissolve in water, the bioavailability is low, the effective blood concentration maintenance time is short, toxic and side effects are large, and a liposome drug delivery system has the advantages of slow release, targeting property and the like, and the good drug delivery effect is widely concerned by people.
At present, researches show that toad eating liposome prepared by taking costustoot, hawk, toad, cod roe and the like as main raw materials is combined with sorafenib to be used, so that the curative effect of sorafenib can be effectively improved, the drug resistance of hepatocellular carcinoma to sorafenib is improved, the recurrence rate is reduced, for the preparation of the toad eating liposome, firstly, the toad eating liposome and the cod roe are uniformly pulped to form slurry, then, the costustoot, hawk tea and the like are ground, sieved and extracted, are uniformly mixed with the slurry and then are sieved, and finally, the powder is freeze-dried.
Therefore, the invention provides a toad feeding liposome preparation device to solve the problems.
