Description

Traditional Chinese medicine composition for preventing and treating lung cancer
Technical Field
The invention belongs to the technical field of traditional Chinese medicines, and relates to a traditional Chinese medicine therapeutic drug which is prepared by taking Chinese herbal medicines as raw material medicines and is used for preventing lung cancer progression and treating lung cancer.
Background
Lung cancer is the most common cause of cancer-related death worldwide, with 180 ten thousand people diagnosed with lung cancer each year, 160 ten thousand of which die from the disease. In the 11 th year from 2000 to 2011, chinese male lung cancer incidence and mortality were the first of all cancers. Lung cancer patients have poor prognosis, with survival rates of only 18% 5 years.
The main reason for the high mortality of lung cancer is that most patients are already late at diagnosis and are accompanied by metastasis. Standard treatments for lung cancer are mainly surgery, radiotherapy, chemotherapy, targeted therapy, immunotherapy, etc., and have achieved remarkable clinical effects. But also causes various adverse reactions, such as bone marrow depression, digestive tract reaction and organ function injury, and symptoms such as nausea, emesis, listlessness, etc., which affect the normal chemotherapy cycle. The targeted therapy and the immunotherapy are the manifestations of accurate treatment of lung cancer, but the toxic and side effects are quite common, such as rash, diarrhea, hypodynamia, hemorrhage and other symptoms, not only affect the life quality of patients, but also need to be forced to stop the medicine.
The current clinical practice lacks effective prevention and treatment means for precancerous lesions and early tumors, and almost all of the effective prevention and treatment means are in the stage of observation follow-up or repeated excision of new lesions. Therefore, a non-invasive lung tumor prevention and treatment scheme without obvious toxic and side effects is needed to appear.
The traditional Chinese medicine is taken as cultural treasure of China, has unique theoretical basis and abundant clinical practice experience, emphasizes the concept of 'people-oriented and tumor-bearing survival', and plays an indispensable role in a comprehensive prevention and treatment system of tumors by improving the constitution of the easily-developed tumor of human body and maximally inhibiting the regrowth of the tumor.
Recurrent metastasis of lung cancer is the leading cause of death. Clinical practice proves that the early intervention of the postoperative traditional Chinese medicine of the tumor patient is beneficial to restoring body vital energy, promoting the recovery of the body after the wound, improving the immune function, relieving postoperative complications, effectively preventing postoperative recurrence and metastasis and prolonging the survival time.
After many clinical patients are treated by operations, radiotherapy, chemotherapy and other rounds of treatment, no medicine is available due to the generation of medicine resistance; or some patients with advanced tumors do not have the indication of radiotherapy and chemotherapy due to the conditions of advanced ages, poor physical conditions and the like. At this time, according to the specific conditions of the patients with the exuberance of pathogenic factors and the healthy energy, a corresponding therapeutic method is formulated, and the purposes of stabilizing focus, preventing recurrence and metastasis, improving life quality and achieving tumor survival can be achieved by adopting the traditional Chinese medicine alone.

Application example 1: pharmacodynamic experiments of in-situ cancer in animals with different traditional Chinese medicine compositions
This application example uses 6 week old male SPF grade C57 model mice (C57 BL/6 LSL-KrasG12D/p53 flox/flox) given by southern model animal company as test animals.
Model mice were randomly divided into 9 groups of a blank group, a group administered with example 1, and a group administered with comparative examples 1 to 7, 6 animals each, and a group administered with comparative examples 1 to 7 was used as a control group.
After the mice of each test group were given deep sleep by ether inhalation, cre virus was inhaled at 0.5X10 7 pfu, simultaneously initiating Kras mutation and p53 cancer suppressor knockout, initiates lung in situ cancer modeling. The blank group was not dosed, and each dosing group was given the drug-containing feed while the modeling was started.
The lung tissue was fixed with 4% paraformaldehyde and paraffin-embedded 8 weeks after administration, immunohistochemical staining was performed on the cancerous index CK-19, and the pathological morphological changes of the lung tissue of each experimental group were observed, and the results are shown in FIG. 1. The stained CK-19 (brown area) was scan quantified with Image J software and the results are shown in Table 1 and FIG. 2.
The results show that compared with the blank, the drug of example 1 has statistically significant inhibition on lung carcinoma in situ tumors, while the drugs of comparative examples 1-7 have no obvious inhibition.
Application example 2: pharmacodynamic experiments of inhibiting animal subcutaneous tumor proliferation by different traditional Chinese medicine compositions
Four groups of 4 week old C57L mice were divided into blank, example 1, comparative example 1 and comparative example 3 groups, 4 each, and inoculated subcutaneously with 2X 10 6 LLC (mouse lung cancer cell) cells were subjected to mouse subcutaneous tumor modelling.
The mice weight and rumen size were recorded every two days on the day of each of the other groups except the blank group, the experiment was ended after 14 days of administration, the mice were euthanized, the tumor tissues were completely stripped, and the tumor volumes were recorded, and the results are shown in fig. 3, which show that the drug of example 1 had a significant inhibitory effect on subcutaneous tumors compared to the blank group, while the two comparative examples had no significant inhibitory effect on subcutaneous tumors of mice.
Application example 3: effect of different Chinese medicinal compositions on tumor-associated macrophages and cytotoxic T cells of subcutaneous tumors
Typically, there are two types of macrophages in the tumor microenvironment. Wherein, M1 macrophage has antigen presenting function, can promote CD8 cytotoxicity T cell (CD 8T) function, CD8T can further kill tumor cells, and M2 macrophage has function of promoting proliferation of tumor cells. If M2 macrophages are increased, CD8T is decreased and the tumor is enlarged and invasive. Thus, the immunotherapeutic strategy for tumors is to increase CD8T while inhibiting the proportion of M2 macrophages.
Single cell suspensions were prepared from subcutaneous tumor tissue of each test group in application example 2, and the ratio of immune cells M2 (CD 45, CD11B, F4/80, CD86+, CD206+) to CD8T (CD 45, CD3+, CD8+) and the ability of mitochondria to produce ATP were examined using flow cytometry and sorted, and the results are shown in FIGS. 4 and 5.
In fig. 4, the drug of example 1 can decrease the proportion of M2 macrophages in the tumor microenvironment of subcutaneous tumor, and can decrease M2 macrophages by one time compared with the blank group, and correspondingly, the drug of example 1 has a remarkable lifting effect on cytotoxic T cells, and the drug of example 1 increases TC cells in tumor cells by 3 times compared with the blank group.
However, the comparative drug did not have a lifting effect on CD8T nor an inhibitory effect on M2.
Further, mitochondrial function assays were performed on the above-described flow-sorted CD8T and macrophage M2 (fig. 5), example 1 increased the ability of CD8T to produce ATP by mitochondria, decreased the ability of M2 to produce ATP, and the comparative group had no effect on ATP productivity of immune cells.
Application example 4: inhibition of lung cancer cell lines by different Chinese medicinal compositions
In order to prove the effect of the traditional Chinese medicine composition on treating lung cancer, the CCK8 experiment is carried out after treating lung cancer cell lines A549, H1299 and PC9 tumor cells for 48 hours in vitro by adopting the medicine of the example 1, and the result is shown in figure 6.
As can be seen from FIG. 6, the Chinese medicinal composition of the present invention inhibits proliferation of tumor cells in a concentration-dependent manner, and A549, H1299 and PC9 intervene in IC for 48H 50 The concentrations were 4.7mg/mL, 4.8mg/mL and 2.8mg/mL, respectively.
The invention is explored by a series of formulas, and on the basis that three monarch drugs of rhizoma polygonati, radix scutellariae and radix astragali have anti-tumor and immunity-regulating functions, peach kernels are added as ministerial drugs, rhizoma atractylodis is taken as adjuvant drugs, and traditional liquorice is taken as conductant drugs, so that the traditional Chinese medicine composition with remarkable effects for preventing and treating lung cancer is obtained.
However, the formula of comparative example 3, in which only the ministerial drug peach kernel is replaced by the bighead atractylodes rhizome, has no effect of inhibiting lung carcinoma in situ in mice. Also, neither comparative example 1 and comparative example 2, in which any drugs were deleted on the basis of the Chinese medicinal composition of the present invention nor comparative examples 4, 5, 6 and 7, in which any drugs were deleted on the basis of comparative example 3, had a remarkable effect of inhibiting lung carcinoma in situ in mice. Compared with the comparative examples, the traditional Chinese medicine composition has obvious lung carcinoma in situ resistance, is particularly expressed on the expression of the immunohistochemical analysis tumor marker CK19, and has obvious statistical difference compared with the comparative examplesP>0.05)。
Similarly, the mouse subcutaneous tumor and in-vitro cytology experiments also prove that the traditional Chinese medicine composition has obvious effect of inhibiting the subcutaneous tumor compared with other comparative example compositions. Further immune cell analysis proves that the cell can inhibit M2 cells, promote immune killer T cells and play a role in improving tumor immunity.
The above embodiments of the invention are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Various changes, modifications, substitutions and alterations may be made by those skilled in the art without departing from the principles and spirit of the invention, and it is intended that the invention encompass all such changes, modifications and alterations as fall within the scope of the invention.
