Problems solved by technology

[0007] For cervical cancer, there is currently no effective therapeutic drug, but radiotherapy, chemotherapy, and surgery are still the main treatments. Merck and GlaxoSmithKline have designed and developed Gardasil for the HPV virus that may cause cervical cancer. ) and Huiyankang vaccine are two vaccines for the prevention of cervical cancer, but both of the above two vaccines have been reported to cause serious side effects

Abstract

The invention relates to application of palmate pinellia tuber protein in the treatment of cervical carcinoma and a preparation thereof. The palmate pinellia tuber protein is total protein, and is prepared by extracting from tubers of palmate pinellia tuber. The palmate pinellia tuber protein has cervical carcinoma resistant activity, and the activity is higher than that of 5-fluorouracil obviously. The invention also relates to a palmate pinellia tuber protein-containing medicinal composition for treating cervical carcinoma.

Description

technical field [0001] The technology relates to the field of traditional Chinese medicine pharmacy, and relates to the use of pinellia palmata protein in treating cervical cancer and its preparation. The palm leaf Pinellia protein is a total protein and has anti-cervical cancer activity. The invention also relates to a pharmaceutical composition for treating cervical cancer containing palm leaf pinellia protein. Background technique [0002] Cervical cancer is a malignant tumor that usually occurs at the junction of the squamous epithelial cells of the cervicovaginal or transition zone and the columnar epithelial cells of the endocervical endometrium. It accounts for more than 50% of malignant tumors in the female reproductive system, and its case fatality rate ranks first in female malignant tumors. It is one of the most common malignant tumors in women. According to the report of the World Health Organization, 459,000 cases of cervical cancer are newly discovered every ...
