Methods and kits for detecting breast cancer or a high risk of breast cancer by measuring bFGF in nipple fluid from subjects compare the levels of bFGF in samples from test subjects with the levels of bFGF in subjects not having breast cancer, where increased levels of bFGF in test subjects indicate the presence of breast cancer, or a high risk of breast cancer, in the test subjects.

The invention discloses a lung cancer and breast cancer treatment compound preparation containing active ingredients of traditional Chinese medicine and a preparation method of the lung cancer and breast cancer compound preparation. The lung cancer and breast cancer treatment compound preparation is made from erianin, taxol, bufalin and bruceine D according to a certain weight ratio. According to the preparation method, liposomes are prepared according to an ethyl alcohol injection method or dropping pills are prepared by taking polyethylene glycol as a base material to obtain the lung cancer and breast cancer treatment compound preparation containing the active ingredients of the traditional Chinese medicine. The form of the compound preparation is compound liposomes and compound dripping pills. According to animal in-vivo anticancer pharmacological experiments, the lung cancer and breast cancer treatment compound preparation containing the active ingredients of the traditional Chinese medicine has obvious inhibiting effect on growth of lung cancer and breast cancer and has higher anticancer activity than chemotherapeutic drug 5-fluorouracil.

The invention relates to the technical field of biology, in particular to application of ICOSL (Inducible Costimulator Ligand) protein in preparation of a kit used for breast cancer prognosis evaluation. According to the invention, the immunohistochemistry technology and a semi-quantitative analysis method of a staining result are employed to analyze the expression level of the ICOSL protein in atumor tissue, and combine with post-operative follow-up information to determine whether the ICOSL protein expression has correlation with the prognosis of a breast cancer patient or not, wherein theICOSL protein can be used for preparing a protein molecular marker for determining the prognosis of the breast cancer patient to have important guiding significance for post-operative monitoring and sequential treatment of the breast cancer patients.

Polynucleotides useful for detecting copy number variation of RNU2 sequences and methods of assessing risk of developing breast or ovarian cancer using molecular combing and/or detection or quantification of BRCA1 expression.

The invention relates to a particle size variable anti-tumor bionic nano preparation based on PLGA, the bionic nano preparation comprises PLGA, bufalin (CS-6), photosensitizer chlorine e6 modified PEGylated graphene oxide quantum dots (GC) and a bionic hybrid membrane (HM), the photosensitizer chlorine e6 (Ce6) is modified on the surfaces of the PEGylated graphene oxide quantum dots, the bufalin (CS-6) and the chlorine modified PEGylated graphene oxide quantum dots (GC) are embdded in PLGA, bionic nano preparation (GCCS-6-coated PLGA [HM]) is synthesized, and a bionic hybrid membrane (HM) is camouflaged on the outer layer of the nano preparation (GCCS-6-coated PLGA) to synthesize the bionic nano preparation (GCCS-6-coated PLGA [HM]). The invention also provides a preparation method for preparing the bionic nano preparation. The bionic nano preparation has excellent tumor infiltration capacity, shows good triple-negative breast cancer resisting effect and invasion and metastasis inhibiting capacity, and can be used as a light/chemotherapy combined treatment bionic nano preparation for triple-negative breast cancer.

The invention relates to the technical field of medical reagent production, in particular to an extraction device for breast cancer tsRNA marker detection reagent production. An extraction device for breast cancer tsRNA marker detection reagent production comprises a first tank body, a centrifugal power system is arranged on the first tank body, a material collecting unit is arranged on the inner wall of the first tank body, a fixing cover is installed at the top of the inner wall of the first tank body, and a centrifugal unit is arranged at the bottom of the fixing cover; the centrifugal unit comprises a centrifugal barrel; the top of the centrifugal barrel is rotationally connected to the bottom of the fixed cover, and a cavity of the centrifugal barrel is communicated with a cavity of the fixed cover; a material throwing belt is spirally distributed on the outer wall of the centrifugal cylinder, and a plurality of groups of material throwing holes are formed in the material throwing belt at equal intervals; and a first rotating rod is arranged on the central axis in the centrifugal cylinder. The device not only meets the integrated operation of crushing, centrifuging, collecting and precipitating in the extraction work, but also reduces the labor intensity at the same time.
