Abstract: The invention provides specific binding proteins and the uses thereof. Particularly, the present invention provides a monoclonal antibody which can effectively bind to epidermal growth factor receptor variant type III (EGFRvIII) or can partially bind to the epidermal growth factor receptor (EGFR) over-expressed in cells, but not bind to EGFR normally-expressed in cells. Furthermore, the present invention said antibody has obvious therapeutic effect on a tumor cell line expressing the EGFRvIII. The invention also provides a method for preparing said monoclonal antibody and a pharmaceutical composition comprising said monoclonal antibody.

Abstract: A vascular embolization gelling agent for sustained release of drugs for treating tumors having a drug and a drug carrier. The drugs are antitumor drugs. The drug carrier includes poloxamer polymer and polyvinylpyrrolidone or gel made of the combination, and may be purified before use. The drug carrier accounts for 5-65% of the gel. The particle size of the gel is in the range of 10 nm-150 ?m. The embolization agent is a liquid gel at normal temperature, to facilitate direct transcatheter injection, and is rapidly solidified to the gel state in body with the increase of the temperature; it is used to encapsulate different drugs on demand, and can achieve dual efficacy of embolization and drug treatment through local sustained release of the drug. The present invention can be used as the embolization agent for endovascular interventional therapy for transcatheter arterial chemoembolization of various benign and malignant tumors.

Abstract: This invention belongs to the nanotechnology field, and discloses a nano drug delivery system with polyethyleneglycol-poly(lactic-co-glycolic acid)-poly-L-lysine (PEG-PLGA-PLL) polymer as the skeleton. The carrier can have the function of passive targeting through control of the carrier particle size. The polymer skeleton is modified through introducing side chains and specific targeting groups, so as to adjust and improve the carrier performance, and enable the carrier to have the function of active targeting. Such carrier material also has the functions of transporting active substances, tumor treatment and diagnosis, ultrasonic contrast, reversing or reducing drug resistance and so on.

Abstract: The present invention provides a method for detecting bladder cancer in a subject, comprising the following steps: (a) providing urine sediment sample from said subject; (b) determining methylation pattern of a given sequence within the promoter CpG islands of one or more genes (known as “gene” infra) in the samples; (c) comparing the methylation pattern from said subject with that from normal subject, wherein the hypermethylation of one or more of genes indicates that said subject is suffering from bladder cancer. The present invention also provides a kit for diagnosing bladder cancer.

Abstract: The invention provides a method for diagnosing susceptibility of individual cancer (e.g. liver cancer), comprising the steps of detecting individual HC56 gene, transcript and/or protein, and comparing it with normal HC56 gene, transcript and/or protein. The difference show the possibility of individual cancer is higher than that in the normal population. The invention also provides the corresponding detection kit.
