The main active ingredient of the traditional Chinese medicine composition is Sophora flavescens, providing with the effect of “bitter and cold”, and “heat and dampness”. The effect “bitter and cold” of Sophora flavescens can relive fever, reduce the diarrhea and clean up the muggy in body which caused by moist and hot weather. The secondary active ingredients are wild Chrysanthemum flower, honeysuckle, mint, Poria cocos, and Atractylodes lancea, which enhance the effect of “bitter and cold”. Among them, wild Chrysanthemum flower, honeysuckle, and mint can eliminate cold and fever, so as to remove the heat-toxicity from the lung; Poria cocos and Atractylodes lancea provide with the effect can strengthen the spleen and remove dampness to clean up the damp in spleen and stomach. However, the “yang-qi” would weak while removing the damp heat, so that cinnamon and clove were added as heat supply to regulate the “bitter and cold” and to prevent the weaken “yang-qi”. Astragalus and Ganoderma lucidum can boost “qi” and strengthen healthy energy to strengthen body resistance. In addition, the effect of “warming yang-qi” and strengthen healthy energy used together can prevent the harmful of spleen and stomach result from the excessive “bitter and cold”. Ligusticum striatum and Aucklandia root can promote blood circulation and activate “qi”, and thus the blocked dampness and the heat-toxicity can be removed via circulation. Therefore, cinnamon, clove, Astragalus, Ganoderma lucidum, Ligusticum striatum, and Aucklandia root are adjuvants. Radix glycyrrhizae was used for regulating ingredients and adjuvants, and has the effect of boosting “qi”, consolidation of exterior and warming spleen and stomach.

2.2 Culture of the human lung adenocarcinoma cell line (A549). Cells were cultured in complete medium (DMEM medium+10% fetal calf serum, pH 7.2), placed in 37° C. 5% CO2 incubator, replaced medium daily. When cells were grown to 80-90% fusion rate, digested with 0.25% trypsin and were passaged after centrifugation. Until cells were grown to a certain amount, diluted into tumor cells suspension in PBS to inject into the test animal model.
2.3 In vitro activity assay and preparation of tumor cell suspension. The selected well-growing tumor cells were digested with 0.25% trypsin and were suspended after centrifugation under sterile conditions. Cell viability was measured and counted using trypan blue staining by a fully automated cell counter. The tumor cell suspension was diluted with PBS to a concentration of 2×107 cells/ml.
2.4 Preparation of human lung cancer xenograft model by injection of A549 tumor cells. 18±2 g nude mice were selected, male and female evenly, and adaptive feeding in experimental animal centers for 7 days. Under sterile conditions, nude mice were disinfected with 75% ethanol, and 0.2 ml of human lung adenocarcinoma A549 cell suspension was subcutaneous injected into the right armpit of nude mice. After injection, the nude mice were returned to the cage, and the spirit diet and defecation of the mice were observed regularly. About 1 week after injection, the built xenograft model was confirmed by observed the grain size hard lumps grown under the skin of injection position.
2.5 Grouping and administration. 2 weeks after tumor cells injection, the nude mice with evenly lump and weight were randomly divided into 8 groups: model control group, cyclophosphamide positive control group, traditional Chinese medicine composition No. 1 with high, medium, low three dose groups, and traditional Chinese medicine composition No. 2 with high, medium, low three dose groups. 7 mice in each group were administered on the day of grouping, and the dose was 0.2 ml/10 g once a day, orally, for 3 weeks.
2.6 Observation index. The body weight and tumor volume of nude mice were measured on the day of administration. The mice were measured every 3 days. The nude mice were weighed and sacrificed three weeks later, and the tumor tissues were weighed. The average tumor weight, tumor growth inhibition rate, tumor volume relative volume, and relative tumor growth rate of each group were calculated.
Calculation Method:
Tumor volume (TV) is calculated as: V=½×a×b2, and a and b represent the length, width and height, respectively.
Relative tumor volume (RTV) is calculated as follows: RTV=Vt/V0, V0 is the tumor volume obtained at grouping (i.e. d0), and Vt is the tumor volume at each measurement.
Relative tumor growth rate T/C (%) (Evaluation index of anti-tumor activity) is calculated as: T/C %=TRTV/CRTV×100%. (TRTV: treatment group RTV; CRTV: negative control group RTV).
2.7 Statistical processing of experimental data. After the Excel table was completed, the SPSS13.0 statistical software package was used for analysis, and the measurement data was referred to as .
3.1 A549 tumor cell count (cell concentration at injection). After the cells were centrifuged and suspended in PBS, 20 μl trypan blue dye was added after diluted 10 μl cell suspension twice, added the suspension into cell counting plate percussion uniformly, and the cell counting plate was inserted into the automatic detecting cytometer. Total cell number: 2.14×107/ml; viable cell number: 1.5×107/ml; the number of dead cells: 6.42-106/ml, cell viability: 95.04%.
3.2 Effect of the tumor volume growth in nude mice model injected with human lung adenocarcinoma cell line (A549)
The results showed that, from the second day of administration, the tumor volume of the two traditional Chinese medicine composition groups were all decreased compared with the tumor volume of the model control group. The tumor volume of the two traditional Chinese medicine composition groups were significantly decreased compared with the tumor volume of the model control group after the 8-20 day of administration (P<0.01, P<0.05), where the tumor volume of the traditional Chinese medicine composition No. 2 with medium dose group at the 5 detection time from day 4 to 20 of administration were different (P<0.01) compared with the tumor volume of the model control group and also the most significant from the data.
3.3 Effect of the relative tumor volume (RTV) and the relative tumor growth rate in nude mice model injected with human lung adenocarcinoma cell line (A549).
The results showed that the RTV of the traditional Chinese medicine composition No. 2 with medium dose group was different compared with the RTV of the model control group (P<0.05), and the rest of the administration groups and model groups has no differences. Compared with the model control group, the T/C % of the traditional Chinese medicine composition No. 1 with high dose group and the traditional Chinese medicine composition No. 2 with medium dose group were 28-70%, and the T/C % of the rest of the administration groups were between 50-90%.
3.4 Effect of the tumor weight in nude mice model injected with human lung adenocarcinoma cell line (A549).
Each tumor weight of the administration groups had difference from the tumor weight of the model control group (P<0.01), and the traditional Chinese medicine composition No. 2 with medium dose group had the smallest tumor lump.
The traditional Chinese medicine composition of the present disclosure has inhibition on the tumor growth of the nude mice injected with human lung adenocarcinoma cell line (A549). Both two the traditional Chinese medicine composition can decrease the tumor volume, RTV, T/C %, and tumor weight of nude mice. The efficacy from high to low was the traditional Chinese medicine composition No. 2> the traditional Chinese medicine composition No. 1> compound cyclophosphamide tablet.
The foregoing is only preferred embodiments of the present disclosure, they are used to illustrate the application of the traditional Chinese medicine composition for treating tumor, and not to limit the scope of the present disclosure. In the scope of the present disclosure described in the claims and their equivalents.
