The invention provides a reagent for diagnosing cervical cancer, which can not only detect the presence or absence of cervical cancer but can also distinguish squamous cell carcinoma and adenocarcinoma from each other, a method for screening cervical cancer by using the reagent, particularly a screening method capable high speed processing by utilizing flow cytometry. The reagent comprises a first labeled antibody reacting with gland cells, a second labeled antibody reacting with adenocarcinoma cells and a third labeled antibody reacting with atypical cervical squamous cells, the antibodies being labeled with mutually distinguishable labels respectively. Preferably, at least one selected from the group consisting of MUC1 antibody, cytokeratin 7 antibody, and cytokeratin 18 antibody is used as the first labeled antibody, at least one selected from the group consisting of cytokeratin 8 antibody and HIK1083 antibody is used as the second labeled antibody, and at least one member selected from the group consisting of NMP179 antibody, p16[INK4A] antibody, Ki-67 antibody, p53 antibody, p21 antibody, EMA antibody, CEA antibody and MIB-1 antibody is used as the third labeled antibody.

The present invention relates to methods of prognosing urothelial carcinoma. In one embodiment, the present invention provides a method of prognosing urothelial carcinoma by determining expression levels of JUN, MAP2K6, STAT3 and / or ICAM1. In another embodiment, the present invention provides an single prognostic panel made up of eight gene markers. In another embodiment, the present invention provides a single prognostic panel made up of eleven gene markers.

A flaviviral replicon-based construct is provided for delivery and expression of granulocyte-macrophage colony stimulating factor to facilitate tumour therapy. In particular, the replicon construct encodes a Kunjin virus replicon having one or more mutations in an NS2A non-structural protein that induce enhanced levels of cellular IFN that synergize with recombinant granulocyte-macrophage colony stimulating factor delivered according to the invention. The construct may be administered intra-tumourally or peri-tumourally to an animal as DNA, RNA or packaged into a VLP, for the therapeutic and / or prophylactic treatment of tumours and cancers such as melanoma, lung carcinoma, cervical carcinoma, lung epithelial carcinoma, prostate cancer, breast cancer, renal carcinoma, colon cancer, epithelial cancers and mesothelioma.

The invention discloses a siRNA sequence for inhibiting survivin gene expression. The siRNA sequence has a broad spectrum siRNA antitumor effect, and has a good inhibitory effect on breast cancer, lung cancer, colon cancer, liver cancer, leukemia, gastric carcinoma, cervical cancer, oral epithelial carcinoma in vitro, and particularly on breast cancer, lung cancer and cervical cancer cells. When entering an organism through a certain manner, the siRNA double strand sequence can efficiently and specially inhibit the expression of related proteins of diseases to silence related disease protein, and can effectively remove the expression of target gene to achieve the purpose of treatment.

The present invention provides a monoclonal antibody for recognizing HPV16-positive cervical epithelial cancer cells and its application. The antibody can detect cervical cancer biomarker HPV16E7 protein in tumor cells with high specificity, thereby being able to distinguish cancerous cervical epithelial cells from cervical abnormalities Or non-cancerous cervical epithelial cells, providing evidence for doctors to accurately diagnose cancer caused by HPV infection, can effectively reduce the missed diagnosis rate of high-grade cervical lesions, provide sufficient time and basis for clinicians to diagnose and treat patients, and improve early cervical disease detection and early intervention. At the same time, unnecessary colposcopy can also be reduced and avoided.

The invention relates to a homogeneous immunoassay reagent kit for detecting beta human chorionic gonadotropin in the technical field of immunoassay, and a preparation method and application thereof. The homogeneous immunodetection reagent kit for β-human chorionic gonadotropin obtained by the method provided by the present invention has a wide range of signal values ​​when analyzed by the photo-excited chemiluminescence immunoassay platform, and reaches the quantitative test standard; the sensitivity is high, and can be accurately detected. The serum or urine β-hCG level is used for in vitro diagnosis; it has good stability and high precision; and by optimizing the analysis system (antibody dosage and buffer solution, etc.), the analysis performance meets the industry standard, which is used for clinical pregnancy diagnosis and dynamic monitoring of hydatidiform mole and hydatidiform mole. Provide reference for the therapeutic effect of choriocarcinoma.

The invention relates to the discovery and application of a plurality of drug lead compounds, in particular to a bis-substituted allyl benzene compound with cytotoxic activity, the key intermediate and the pharmaceutical salt of the compound, also to the preparation method, the drug composition and the medicinal purpose of the allyl benzene derivative and the key intermediate of the allyl benzenederivative, belonging to the fields of organic chemistry, medicinal chemistry and pharmacology. The compound of the discovery in vitro inhibits the activity of six human tumor cell lines-human prostate cancer cells (PC-3), nasopharyngeal carcinoma cells (CNE), oral epithelial carcinoma cells (KB), human lung cancer cells (A549), human hepatoma cells (BEL-7404) and human cervical cancer cells (Hela), and can be expected for antitumor drug purpose.
