Embodiment 1

[0016] A drug combination for improving sensitivity to fluorouracil, characterized in that it includes fluorouracil and hydroxychloroquine linolenate, wherein the concentration of fluorouracil is 1.25-10 μmol / L, and the concentration of hydroxychloroquine linolenate is 10-160 μmol / L, set Fluorouracil single-drug group, hydroxychloroquine linolenate single-drug group, and fluorouracil combined with hydroxychloroquine linolenate group, wherein the ratio of fluorouracil to hydroxychloroquine linolenate in the fluorouracil combined with hydroxychloroquine linolenate group was 1:8, each group The experiment was repeated 3 times independently, and the tumor cells were added and cultured on the micro-culture plate for 24h, 48h and 72h respectively, and the data were observed and recorded.

Embodiment 2

[0018] A drug combination that increases fluorouracil sensitivity in rectal cancer.

Embodiment 3

[0020] In vitro verification:

[0021] 1. The concentration of 5-Fu single-drug group was 1.25-10 μmol / L; the concentration of AHQ single-drug group was 10-160 μmol / L; when the ratio of 5-Fu combined with AHQ group was 1:8, the action time of 48 and 72 hours could significantly improve the 5-Fu Chemosensitization of Fu on HCT116 cells leading to enhanced antitumor activity. See Table 1-3 and figure 1 .

Abstract

The invention discloses a pharmaceutical composition for improving fluorouracil sensitivity. The pharmaceutical composition is characterized in that the pharmaceutical composition comprises fluorouracil and hydroxychloroquine linolenate, wherein the concentration of fluorouracil is 1.25 to 10 [mu] mol/L, and the concentration of hydroxychloroquine linolenate is 10 to 160 [mu] mol/L; a fluorouracilsingle-drug group, a hydroxychloroquine linolenate single-drug group and a fluorouracil combined hydroxychloroquine linolenate group are arranged; each group of experiments is independently repeatedfor three times; tumor cells are added and then are cultured on a micro-culture plate for 24 hours, 48 hours and 72 hours respectively; and data of the tumor cells are observed and recorded. The invention further discloses an application of the pharmaceutical composition for improving fluorouracil sensitivity in colorectal cancer. The pharmaceutical composition has the advantages that fluorouraciland hydroxychloroquine linolenate are combined for use, so that the chemosensitivity of fluorouracil can be improved, and the treatment effect is improved; the medication compliance of colorectal cancer patients can be improved; and meanwhile, the pain of the patients can be relieved.

Description

technical field [0001] The present invention relates to the technical field of medicine, in particular to a drug combination for improving fluorouracil sensitivity and the application of the drug combination. Background technique [0002] Colorectal cancer (CRC) is one of the leading causes of cancer death and is the second most common cancer in women and the third most common cancer in men. In recent years, the incidence of colorectal cancer in China has been increasing. In 2015 alone, 191,000 patients died in China, and its death rate ranks fifth among all cancers. The clinical treatment for CRC is mainly surgical resection of the primary tumor; and when the disease progresses or metastasizes, chemotherapy is used for treatment. Chemotherapy has been the standard treatment for clinical treatment of CRC. According to the National Comprehensive Cancer Network (NCCN) guidelines (2018 edition), the first-line treatment for advanced colorectal cancer is based on 5-fluorouraci...
