YUAV TSUM SIV LI CAS

Cov Khoom Siv Kuaj Mob Dawb Prostate Specific Antigen (fluorescence immunochromatographic assay) yog qhov kev ntsuam xyuas fluorescence immunochromatographic rau kev kuaj pom ntau ntawm cov tshuaj Prostate Specific Antigen (fPSA) hauv cov ntshav tib neeg lossis cov ntshav. Qhov piv ntawm fPSA / tPSA tuaj yeem siv rau hauv kev kuaj mob sib txawv ntawm mob qog nqaij hlav prostate thiab benign prostatic hyperplasia. Tag nrho cov qauv zoo yuav tsum tau lees paub los ntawm lwm txoj kev. Qhov kev xeem no yog rau kev siv kho mob xwb.

LUS QHIA

Cov tshuaj prostate-specific antigen dawb (fPSA) yog cov tshuaj prostate-specific antigen uas tso tawm rau hauv cov ntshav hauv daim ntawv dawb thiab tso tawm los ntawm cov hlwb epithelial ntawm prostate. PSA (Prostate Specific Antigen) yog cov hlwb epithelial ntawm prostate tsim thiab tso tawm rau hauv cov phev thiab yog ib qho ntawm cov khoom tseem ceeb ntawm cov ntshav seminal. Nws muaj 237 cov amino acid residues thiab nws qhov hnyav molecular yog li 34kD. Nws muaj cov haujlwm serine protease ntawm cov glycoprotein ib txoj saw hlau, koom nrog hauv cov txheej txheem ntawm cov phev liquefaction. PSA hauv cov ntshav yog qhov sib npaug ntawm cov PSA dawb thiab PSA ua ke. Cov theem ntshav plasma, hauv 4 ng / mL rau tus nqi tseem ceeb, PSA hauv mob qog nqaij hlav prostate Ⅰ ~ Ⅳ lub sijhawm ntawm qhov rhiab heev ntawm 63%, 71%, 81% thiab 88% feem.
