Bilirubin hmoovyog ib hom kua tsib pigment, uas yog lub ntsiab pigment nyob rau hauv tib neeg cov kua tsib. Nws yog txiv kab ntxwv-daj thiab lub ntsiab metabolite ntawm hlau porphyrin tebchaw. Tus nqi ntawm bilirubin feem ntau yog hais txog tus nqi ntawm cov ntsiab lus bilirubin nyob rau hauv qhov ntsuas ib txwm, uas tau muab faib ua tag nrho cov qib bilirubin, qib ncaj qha bilirubin, thiab qib ntshav tsis ncaj bilirubin. Tus nqi ib txwm yog 5.1 ~ 19.0 μ mol / L, 1.7 ~ 6.8 μ mol / L, 3.4 ~ 12 μ mol / L.
Abnormality ntawm bilirubin
Muaj peb qhov laj thawj rau bilirubin abnormality, tshwj xeeb tshaj yog raws li hauv qab no: thawj yog prehepatic; Qhov thib ob nam yog hepatocyte; Qhov thib peb nam yog posthepatic. Analysis yog raws li nram no:
1. Prehepatic feem ntau yog vim qhov nce ntawm indirect bilirubin. Muaj ob qho laj thawj: ntawm ib sab, kev puas tsuaj ntawm cov qe ntshav liab nce, thiab cov nyiaj tsis ncaj ntawm bilirubin tsim tawm, uas ntau tshaj lub siab lub peev xwm. Lub sijhawm no, qhov tsis ncaj ncees bilirubin yuav nce ntxiv; Ntawm qhov tod tes, Gilbert syndrome, tus kab mob autosomal recessive genetic disease, yog ib qho kev tsis ncaj ncees bilirubin nce, feem ntau yog vim qhov txawv txav ntawm glucuronosyltransferase. Qhov enzyme no txawv txav. Tom qab lub siab ingests indirect bilirubin, nws feem ntau ua ke nrog glucuronic acid los tsim bilirubin ncaj qha nyob rau hauv qhov kev txiav txim ntawm no enzyme. Yog tias qhov enzyme no tsis zoo, tsis ncaj ncees lawm bilirubin tsis tuaj yeem hloov mus rau hauv cov tshuaj bilirubin ncaj qha, uas tseem qhia tau tias muaj kev nce ntxiv hauv bilirubin.
2. Lub siab hlwb raug puas tsuaj, uas yog, bilirubin nce vim muaj kab mob siab. Thaum lub siab puas lawm, lub siab ua haujlwm ntawm lub siab nqus, tsim thiab tso tawm bilirubin yog qhov tsis zoo, thiab qhov tsis ncaj thiab ncaj qha bilirubin nce.
3. Posthepatitic. Yog hais tias muaj cov qog thiab pob zeb nyob rau hauv lub biliary ib ntsuj av thiab mechanical biliary obstructive tshwm sim, ncaj qha bilirubin mas yog nce, thiab tus neeg mob tuaj yeem pom cov quav dawb. Vim tias qhov kawg metabolite ntawm bilirubin yog fecal bilirubin, uas feem ntau yog daj, cov quav yog daj. Yog tias muaj kev cuam tshuam, cov quav yuav dawb, thiab cov zis xim yuav nkag mus tob heev vim tias cov bilirubin ncaj qha tuaj yeem nkag mus rau hauv cov ntshav, Cov zis tawm tawm sab nraud ntawm lub cev, yog li cov xim ntawm cov zis yuav pom zoo li cov tshuaj yej tsaus. Yog tias qhov kev cuam tshuam loj heev, cov xim ntawm cov zis tuaj yeem tshwm sim raws li cov tshuaj yej muaj zog.
Yuav ua li cas ntsib qhov txawv txav ntawm bilirubin?
Raws li tau hais los saum toj no, yog tias tus neeg mob pom tias tus nqi ntawm bilirubin muaj kev pheej hmoo siab thaum lub sijhawm kuaj, nws feem ntau qhia tau tias tus neeg mob muaj kab mob siab tsis zoo lossis cov kab mob hauv lub cev. Lub sijhawm no, kev kuaj xyuas ntxiv yuav tsum tau ua kom txiav txim siab qhov twg ntawm tus kabmob; Yog tias tus nqi ntawm bilirubin qis, nws yuav yog vim cov qe ntshav liab puas thiab cov tsos mob ntawm cov ntshav liab tshwm. Tus neeg mob yuav tsum tau kuaj ntxiv txhawm rau txiav txim siab qhov mob hnyav.
Nws raug pom zoo tias cov neeg mob yuav tsum mus rau lub tsev kho mob tsis tu ncua rau kev kuaj mob; Nyob rau tib lub sij hawm, peb yuav tsum tsim kom muaj kev noj qab nyob zoo, tsis txhob nyob lig, mus pw ntxov thiab sawv ntxov txhua hnub; Noj cov zaub mov kom sib npaug, thiab tsis txhob overeat.
