The invention relates to the field of immunology, endocrinology and oncology and, in particular, the generation of a combined immune response to determined growth factors and hormones. A synergic effect, outlined herein, between growth regulating factors (EGF, TGF and VEGF) and hormones involved in the sexual hormones release cascade or reproduction (GnRH, LH, FSH) stimulates the anti-tumor response which is expressed as a reduction in the tumor mass and an increase in the survival time.

The invention also provides pharmaceutical compositions comprising said antibody proteins. The invention furthermore is concerned with the use in the manufacture of a medicament for the treatment of cancer.

The invention relates to the field of medical equipment and oncology, and relates to a puncture biopsy needle with optical fiber probes. The puncture biopsy needle with optical fiber probes mainly comprises a host machine, a puncture needle, optical fiber probes and a display device, wherein the optical fiber probes are arranged on the outer edge of a needle core of the puncture biopsy needle. According to the puncture biopsy needle, the optical fiber probes are adopted to transmit lasers to the tip of the puncture biopsy needle, and therefore the real-time acquisition of Raman spectrum signals of pinpoint contact tissues or cells is achieved, and the signals are automatically analyzed and monitored. When the puncture biopsy needle is used, the Raman spectrum of the pinpoint tissues and cells can be monitored in real time in punctures, and by acquiring information of cancerous status and the like of the current needle tip contact tissues and cells through analyzing spectrum signals, tumors can be identified from normal tissues in real time in punctures, which helps doctors to find out cancerous tissues through biopsy more precisely, therefore the positive rate of biopsy is increased, complications caused by vascular injury and other normal tissue injuries are avoided, and the safety of punctures is improved.

The invention provides a plasma miRNA biomarker related to colorectal cancer diagnosis and an application thereof, and belongs to the field of biotechnology and oncology. The plasma miRNA biomarker related to colorectal cancer diagnosis is plasma miR-21. The present study suggests that plasma miRNAs are mainly from secretion of tumor tissues or are induced by death and dissociation of tumor cells, but the miRNAs with differential expression in the tissues do not absolutely experience differential expression in the plasma, and some miRNAs are even reverse. Although the miR-21 has been determined to be capable of being used as the marker in colorectal cancer tissues, results in the reports of peripheral plasma samples are not uniform, the innovation of the invention lies in that the expression trend uniformity of the plasma miR-21 and the tissue miR-21 is determined, the plasma miR-21 can be used as a diagnostic marker and is non-invasive, so that the plasma miR-21 can be applied to future clinic.

The invention belongs to the field of molecular biology and oncology, and particularly relates to a group of esophageal cancer detection markers and application thereof in preparation of an esophagealcancer screening kit. The esophageal cancer detection markers serve a reagent capable of specifically detecting CA19-9, CYFRA21-1, CA125, FBXW7 and FAT1 or a group of gene expression products; the esophageal cancer early diagnosis kit is a liquid-phase protein chip kit. According to the esophageal cancer marker, a combination of the CA19-9 monoclonal antibody, the CYFRA21-1 monoclonal antibody, the CA125 monoclonal antibody, the FBXW7 monoclonal antibody and the FAT1 monoclonal antibody is used as the esophageal cancer marker for the first time, and is applied to preparation of a liquid-phaseprotein chip with high detection sensitivity and specificity for early esophageal cancer, the detection sensitivity of the liquid-phase protein chip to esophageal cancer is 93.5%, and the specificityof the liquid-phase protein chip to esophageal cancer is 73.9%.

The invention belongs to the field of medical immunology and oncology and discloses thymus-dependent lymphocyte antigen epitope peptides of primary liver cancer related antigens and application thereof. The antigen epitope peptides are antigen peptides separately restricted by HLA-A0201, HLA-A1101, hLA-A2402, HLA-A3101, HLA-A0206, HLA-A0207, HLA-A3303, HLA-A3001, HLA-A0203, HLA-A1102, HLA-A0301, HLA-A0101 and HLA-A2601 molecules, and the varieties of the antigen epitope peptides sum to 110. The antigen epitope peptides can specifically bind to cytotoxic thymus-dependent lymphocytes so as to stimulate the activation, proliferation and differentiation of the thymus-dependent lymphocytes, so anti-tumor immune effect is exerted; the antigen peptides can be used for preparing therapeutic and preventive vaccines for liver cancer, can also be used for preparing detection reagents for detecting liver cancer-related antigen-specific cytotoxic thymus-dependent lymphocytes, and have potential application value in prevention, treatment and diagnosis of liver cancer.

A simple and potentially disposable compact probe of FIG. 1, which is primarily aimed to be used for radio-guided or fluorescence-guided surgery, diagnostics or biopsy, and method of using it, is invented. The novel method reduces limitations inherent to the existing technologies. It consists in shifting most of the functions (signal analysis, detector controls and user visual and audio interfaces) from the probe to an external personal computer connected with the probe via wireless link. Maximum simplification and miniaturization of the probe itself makes it potentially disposable, supplied in sterile package similar to disposable syringe. Due to use of single photon time-resolved counting photo-sensors and microelectronic circuits with sub-nanosecond timing, the probe can be used with fluorescent markers as well. New probe should enhance efficiency of medical procedures and open opportunities for more wide application of the intra-operative probing techniques in medical practice, especially in oncology. Applications other than medical are also possible.
