Description

A kind of test kit measuring DDi and preparation method thereof
Technical field
The present invention relates to medical science and technological field of biochemistry, a kind of test kit measuring DDi and Its preparation method.
Background technology
Fibrinolytic system is the most important anticoagulation system of human body, is made up of 4 kinds of major parts: plasminogen, fibre Dissolved preferment activator, fibrinolysin, plasmin inhibitor, when fibrin coagula is formed, activate at histiotype plasminogen In the presence of thing (tpA), Plasminogen activation is converted into fibrinolysin, and plasmin solution preocess starts, plasmin degradation fiber Albumen coagula forms various solvable fragment, forms fibrin degradation product (FDP), and fibrin degradation product (FDP) is by following material: X- Oligomer, DDi, intermediate segment, fragment E form.Wherein, X-oligomer and D-aggressiveness are all containing DDi unit.
Human body fibrinolytic system, its normal permeability to holding blood vessel wall, maintain flow regime and the tissue repair of blood Playing an important role, DDi increases explanation at plasma levels and there is Secondary cases fibrinolytic process, and first generates thrombin, after Have again fibrinolytic system to activate, and also be reflected in thrombotic local plasmin activity or concentration exceedes blood plasma 2 ‰-anti-fibre Antiplasmin activity or concentration, thromboembolism treatment refers to carry out activated fiber fibrinolytic system with medicine, generally puts into a kind of fibrinolysin Former activator such as Enzyme In Urine, streptokinase or Tissue plasminogen activator (tpA), make a large amount of fibrinolysin generate, thus accelerate The most thrombosed dissolving, FDP or DDi generate, then show to reach thrombolytic effect.
In fibrinolytic protein catabolite, the thrombolysis activity after only DDi crosslinking fragment can reflect thrombosis, therefore, In theory, the detection by quantitative of DDi can quantitative response medicine thrombolytic effect, can be used for diagnosing, screening the blood being newly formed Bolt.
Measure fibrinolytic system Main Factors, for Clinics and Practices fibrinolytic system disease and have related disorders with fibrinolytic system, Such as tumor, pregnancy syndrome, and thromboembolism treatment monitoring, have great significance.
The level of fibrin degradation product (FDP) D raises, and shows internal to there is fibrin degradation process frequently.Cause This, fiber DDi is deep venous thrombosis (DVT), pulmonary infarction (PE), the key index of disseminated inravascular coagulation (DIC).
At present, the method for detection DDi has enzyme linked immunosorbent assay, colloidal gold method, but enzyme linked immunosorbent assay is grasped Make complexity, the longest, colloidal gold method can qualitative or sxemiquantitative, but the most inadequate at quantitative aspect, and above two method All there is the defect that accuracy is low.
