It is an object of the present invention to provide a polymer material, the histocompatibility of which has been improved by irradiation of ion beam, which prevents an aneurysm having a risk of rupture from actually rupturing. The present invention provides a material for treating aneurysms, which is composed of a polymer material containing carbon as a constitutional element, and which is produced by modifying at least a portion of the surface thereof by ion bombardment.

The invention belongs to the field of polymer material and biomedical engineering, particularly relates to drug-loaded silica embolism microsphere and a preparation method thereof. Through technical improvement, silica microsphere is prepared into micron microsphere, hydrophilic polyethylene glycol coupling agent is coupled onto the surface of silica microsphere by efficient Huisgen cycloaddition reaction to form a neutral hydrophilic layer, so that the microspheres can be stably and uniformly dispersed in an aqueous medium to facilitate operation of arterial embolization; meanwhile, silica embolism microsphere has a nano porous structure which can adsorb chemicals, so as to reach the purpose of slow release of drug for treatment while achieving arterial embolization, which further improves the therapeutic effect. The embolism microsphere provided by the invention has good histocompatibility, is mainly used for arterial embolization treatment of diseases, especially suitable for arterial embolization treatment of hepatic tumor, and has broad application prospect.

Marker compounds indicative of variations in physiological conditions, genetic defects or disease states have been found to be present in apocrine sweat and, in many conditions, these markers are present in apocrine sweat in elevated levels when compared to blood. These markers are collected and / or detected in apocrine sweat and used as an indicator that a disease state or particular physiological condition exists. A skin patch, wipe or electronic detector for vapors released from apocrine sweat are used to indicate the existence of a disease state or changing physiological condition. The patch or wipe can include in monoclonal antibodies or other chemical compounds that can indicate the presence of specific markers. This may include indicators that render visible, the existence of a reaction between the monoclonal antibody or chemical compound and the marker compound to indicate the existence of the condition being tested for. Various different disease states can be detected including, but not limited to heart disease, cancer, autoimmune disease, viral or bacterial disease, renal disease, drug intoxication and other systemic illnesses. Fertility for conception and histocompatibility for organ transplantation of individuals should also be detectable.
