D-dimer yog ib qho khoom degradation ntawm fibrin, uas feem ntau yog siv rau hauv coagulation function tests.Nws qib ib txwm yog 0-0.5mg / L.Qhov nce ntawm D-dimer tej zaum yuav muaj feem xyuam rau lub cev nqaij daim tawv xws li cev xeeb tub, los yog nws muaj feem xyuam rau cov kab mob pathological xws li kab mob thrombotic, kab mob sib kis, thiab qog nqaij hlav malignant.Nws raug nquahu kom cov neeg mob mus rau lub tsev kho mob hematology department kom kho raws sijhawm.

1. Physiological yam:
Thaum cev xeeb tub, cov tshuaj hormones hauv lub cev yuav hloov pauv, uas tuaj yeem txhawb kev degradation ntawm fibrin los tsim D-dimer, uas tuaj yeem ua rau nce D-dimer hauv cov ntshav, tab sis feem ntau nws yog nyob rau hauv qhov qub ntau lossis nce me ntsis, uas. yog ib qho tshwm sim ntawm physiological thiab feem ntau tsis tas yuav tsum tau kho tshwj xeeb.

2. Pathological yam:
1. Cov kab mob thrombotic: Yog tias muaj cov kab mob thrombotic nyob rau hauv lub cev, xws li cov hlab ntsha sib sib zog nqus thrombosis, pulmonary embolism, thiab lwm yam, nws yuav ua rau cov ntshav ua haujlwm tsis zoo, ua rau cov ntshav hauv lub xeev hypercoagulable, thiab txhawb cov fibrinolytic system hyperactivity, ua rau D-dimerization Qhov nce ntawm fibrin degradation cov khoom xws li lub cev thiab lwm yam fibrin, uas nyob rau hauv lem ua rau kom nce D-dimer nyob rau hauv cov ntshav.Lub sijhawm no, raws li kev qhia ntawm tus kws kho mob, recombinant streptokinase rau kev txhaj tshuaj, urokinase rau kev txhaj tshuaj thiab lwm yam tshuaj tuaj yeem siv rau kev kho mob los tiv thaiv kev tsim cov thrombus;

2. Cov kab mob sib kis: Yog tias muaj kab mob loj heev hauv lub cev, xws li sepsis, cov kab mob pathogenic hauv cov ntshav proliferate sai heev hauv lub cev, cuam tshuam cov ntaub so ntswg thiab cov kab mob ntawm lub cev tag nrho, ua kom puas microvascular system, thiab tsim capillary thrombosis. nyob rau hauv tag nrho lub cev.Nws yuav ua rau kev nthuav tawm intravascular coagulation thoob plaws hauv lub cev, txhawb kev txhim kho ntawm fibrinolytic kev ua haujlwm hauv lub cev, thiab ua rau D-dimer nce hauv cov ntshav.Lub sijhawm no, tus neeg mob tuaj yeem siv tshuaj tiv thaiv kab mob xws li cefoperazone sodium thiab sulbactam sodium rau kev txhaj tshuaj raws li kws kho mob qhia.;

3. Cov qog nqaij hlav malignant: cov qog nqaij hlav qog nqaij hlav yuav tso tawm cov tshuaj procoagulant, txhawb kev tsim cov thrombus hauv cov hlab ntsha, thiab tom qab ntawd ua kom cov kab mob fibrinolytic, ua rau muaj D-dimer hauv cov ntshav.Lub sijhawm no, kev txhaj tshuaj paclitaxel, Tshuaj Khomob nrog kev txhaj tshuaj xws li cisplatin.Nyob rau tib lub sijhawm, koj tuaj yeem ua kev phais kom tshem tawm cov qog raws li tus kws kho mob cov lus qhia, uas yog qhov zoo rau kev rov qab los ntawm tus kab mob.
