Technical field

The present invention relates to the new application of Chinese medicine compound Zuojin prescription and chemotherapy drugs in combination treatment.

Background technology

Colorectal cancer is one of malignant tumor common in digestive system, including colon cancer and rectal cancer, and the whole world every year There are about 1,200,000 patients to be diagnosed as colorectal cancer, and have more than 600,000 patients and directly or indirectly die from knot directly Intestinal cancer, its M & M lays respectively at the 3rd and the 4th.The sickness rate of male's colorectal cancer is higher than Women, colorectal cancer incidence rate age bracket below 40 years old is relatively low, but can increase along with the increase at age.Greatly Intestinal cancer be China most common be also one of malignant tumor the most of greatest concern.From the nineties, developed country Colorectal cancer incidence rate start to decline year by year, but the developing Asian countries such as China rise the most year by year, man In property patient, this epidemiologic feature becomes apparent from, and the healthy of the mankind in serious threat.

Operation is considered as the Main Means treating colon cancer at present, but due to colon cancer morbidity disguise and examine The limitation for the treatment of means, most colon cancer have been enter into colon cancer morbidity middle and advanced stage, are unsuitable for operative treatment when finding. Typically take intestinal cancer based on chemotherapy clinically at present, radiotherapy, biological immune treatment etc. are auxiliary treatment means. But chemotherapy has huge untoward reaction, causes acute liver damage and kidney injury etc., greatly limit chemotherapeutics and use Amount, hinders the performance of efficacy of drugs, and radiotherapy in the treatment is easily caused radioactivity brain, spinal cord injury, radioactivity brain in addition The complication such as nerve injury, the damage of radioactivity salivary gland and radioactive rear induction cancer.

Therefore, Chinese medicine combines chemotherapeutic treatment middle and advanced stage intestinal cancer and increasingly shows advantage.Chinese medicine is to colorectal cancer Therapy study has been directed to the fields such as tumorigenesis, death, aging, plays in treatment of colorectal cancer Positive effect.A large amount of medical practices prove: the auxiliary treatment after Chinese medicine coordinates colorectal neoplasm operation excision (is changed , targeting, gene, radiation, endocrine, biotherapy etc.), reduction is recurred, alleviates toxicity, prolonged Long patient life cycle, improve patients ' life quality and have obvious advantage. additionally, the advantage of lower cost of Chinese medicine, Practicality is wide.But Traditional Chinese Medicine Anti intestinal cancer preparation is dull, and uncertain therapeutic efficacy is cut, and there is no at present and has extensive therapeutical effect Clinical preparation come out, most of Chinese medicine preparation for auxiliary medicine for treatment, its clinical practice lack specification, and should Undesirable by effect, seriously constrain extensively applying and obtaining recognizing of international community of anti-intestinal cancer Chinese medicine and compound recipe thereof Can.

As shown in Figure 10, Figure 10 is blank to result of the test, 1.00 μ g/mL Zuojin prescriptions, 50.0 μ g/mL 5-FU, 100.00 μ g/mL 5-FU, 1.00 μ g/mL Zuojin prescriptions combine 50.0 μ g/mL 5-FU and 1.00 μ g/mL Zuojin prescriptions connection Close 100.0 μ g/mL 5-FU and act on morphocytology microscope observation figure (× 200) of HT-2924h.

Can be seen that from result of the test, after Hoehest33258 fluorescence staining, under fluorescence microscope, see blank group HT-29 cell membrane is all complete, and nuclear morphology is full, and caryoplasm coloring is shallow, and even density is consistent, sees Figure 10 A；1.00 ug·mL^-1Zuojin prescription, 50.00ug mL^-15-FU、100.00ug·mL^-1After 5-FU effect 24h, there is allusion quotation in cell Type apoptosis morphological characteristic: cell membrane shrinkage, the nucleus fluorescence that relatively diminishes is remarkably reinforced, and becomes highly block, sees Figure 10 B, 10C, 10D；Zuojin prescription+5-FU (1.00+50.00), Zuojin prescription+5-FU (1.00+100.00) combine use Medicine effect 24h, cell is in addition to features described above, it is seen that apoptotic body number is significantly more than each independent medication group, sees figure 10E、10F。

To sum up can obtain, Zuojin prescription and 5-FU drug combination are than Zuojin prescription, or the treatment that the independent medication of 5-FU is to intestinal cancer Effect is more preferable, Zuojin prescription and 5-FU drug combination, significantly improves the thin of people Normal Colon rectal mucosa epithelial cell FHC Born of the same parents' survival rate, significantly reduces the cytotoxic effect of 5-FU, by promoting Bax in colon-cancer cell HT-29 cell The high expressed of albumen and the low expression of Bcl-2, Survivin albumen, promote the apoptosis of colon cancer cell.The present invention Achievement in research to reduce clinical anti-intestinal cancer chemotherapeutics toxic and side effects, improve therapeutic effect, have great Meaning.
