Dab tsi yog qhov cuam tshuam empirical (cov txiaj ntsig) ntawm quercetin?
1. Quercetin pab kho tus kab mob COVID-19
Ib 30-hnub randomized, tswj thiab qhib-label kawm ntawm 152 COVID-19 cov neeg mob sab nraud tau sau tseg:
Quercetin (hnub koob tshuaj 1000 mg) yog siv nrog rau kev saib xyuas tus qauv hauv cov theem pib ntawm tus kab mob kis los pab txhim kho cov txiaj ntsig kho mob, suav nrog: txo qis kev xav tau thiab lub sijhawm mus pw hauv tsev kho mob, xav tau kev kho tsis muaj pa oxygen, kev kho mob hnyav, thiab tuag.
Xaus: Rau COVID-19 kab mob, quercetin ua ke nrog cov qauv kev kho mob yuav pab txhim kho cov tsos mob thaum ntxov thiab pab txo qis qhov mob ntawm COVID-19, tab sis nws raug txwv los ntawm cov qauv me me thiab xav tau kev tshawb fawb loj ntxiv mus ntxiv siv tau.
2. Quercetin tswj cov ntshav siab
Ib qho kev ntsuas meta-kev soj ntsuam (7 kev tshawb fawb nrog 587 tus neeg koom) tau sau tseg:
Quercetin supplementation muaj cov nyhuv hypotensive thiab zoo tshaj plaws hauv koob tshuaj ntau dua 500 mg ib hnub twg thiab ntau tshaj 8 lub lis piam ntawm kev siv.
Xaus: Quercetin supplementation muaj cov txiaj ntsig ntawm kev tswj cov ntshav siab, tab sis vim tsis txaus cov qauv loj, heterogeneity, thiab lub sij hawm luv luv, cov kev tshawb fawb loj tseem yuav tsum tau ua kom paub meej tias muaj kev kho ntxiv rau kev kub siab.
3. Quercetin muaj txiaj ntsig zoo rau kev tswj ntshav qab zib
Ib qho kev tshuaj ntsuam xyuas metabolic (suav nrog 9 qhov kev sim tshuaj ntsuam xyuas randomized nrog 781 tus neeg uas muaj cov kab mob metabolic thiab lwm yam teeb meem) tau sau tseg:
Cov nyhuv ntawm quercetin supplementation hauv kev txo cov ntshav qabzib ceev yog qhov tseem ceeb tshaj plaws hauv cov kev tshawb fawb Loj dua lossis sib npaug rau 8 lub lis piam nrog ib hnub koob tshuaj ntau dua lossis sib npaug rau 500 mg. Tsis tas li ntawd, cov nyhuv ntawm quercetin hauv kev txo qis cov tshuaj insulin yog qhov tseem ceeb tshaj plaws hauv cov neeg muaj hnub nyoog <45 xyoo thiab nyob rau ib hnub koob tshuaj ntau dua lossis sib npaug li 500 mg / hnub.
Xaus: Rau cov neeg mob uas muaj cov kab mob metabolic thiab lwm yam kab mob, quercetin supplementation yuav muaj txiaj ntsig zoo rau kev tswj glycemic.
4. Quercetin muaj txiaj ntsig zoo rau kev mob plab
Ib qho kev ntsuam xyuas meta (7 randomized, ob leeg dig muag kev tshawb fawb nrog 549 tus neeg koom) tau sau tseg:
Quercetin / onionin supplementation muaj qhov tseem ceeb C-reactive protein txo cov nyhuv, tshwj xeeb tshaj yog nyob rau hauv cov neeg uas muaj ib hnub twg ntau tshaj 500 mg thiab CRP tsawg dua 3 mg / l.
Lwm qhov kev tshuaj ntsuam xyuas meta (suav nrog 15 qhov kev sim tswj kev sim) tau sau tseg:
Rau cov neeg koom nrog tus kab mob, quercetin supplementation muaj cov tshuaj tiv thaiv kab mob (txo C-reactive protein thiab interleukin-6). Cov txheej txheem hauv qab no tuaj yeem cuam tshuam nrog inhibition ntawm qhov kev hloov pauv ntawm cov khoom siv hluav taws xob kB, inhibition ntawm leukotrienin tsim, cuam tshuam nrog AMPK / SIRT1 txoj hauv kev, thiab txhawb kev tsim cov nitric oxide.
Cov ntsiab lus: Quercetin supplementation muaj txiaj ntsig zoo rau kev txhim kho cov kab mob hauv lub cev, tab sis vim yog qhov sib txawv ntawm cov kev tshawb fawb, xav tau kev tshawb fawb ntxiv kom paub meej tias nws.
5. Quercetin tswj cov ntshav lipids
Kev tshuaj xyuas thiab kev tshuaj xyuas metabolic (16 randomized, kev sim tshuaj placebo nrog 1575 tus neeg koom nrog metabolic syndrome thiab lwm yam teeb meem) tau sau tseg:
Quercetin supplementation txo qis tag nrho cov roj cholesterol, LDL cholesterol, thiab C-reactive protein ntau ntau.
Xaus: Quercetin tuaj yeem muaj txiaj ntsig zoo rau kev tswj hwm lipid, tab sis vim muaj qhov sib txawv ntawm cov kev tshawb fawb suav nrog, xav tau kev sim loj ntxiv los txhawb nws.
6. Quercetin tiv thaiv kab mob ua pa sab sauv
Ib qho randomized, ob-dig muag, kev sim tshuaj placebo (12 lub lis piam, 1002 tus neeg koom ntawm txhua lub hnub nyoog) tau hais tias:
Kev soj ntsuam ntawm cov neeg noj qab haus huv muaj hnub nyoog tshaj 40 xyoo tau pom tias qhov mob ua pa sab saud hnyav thiab tag nrho cov hnub hauv 1000 mg txhua hnub pab pawg piv nrog cov placebo.
Xaus: Rau cov hnub nyoog nruab nrab thiab cov hnub nyoog nruab nrab uas muaj kev noj qab haus huv, quercetin supplementation yuav pab tau rau kev tiv thaiv kab mob ua pa, tab sis txwv los ntawm cov qauv me me, tseem xav tau kev tshawb fawb ntxiv los txhawb nws.
7. Quercetin muaj cov khoom zoo los tiv thaiv kab mob qog noj ntshav thaum siv los ua ke nrog curcumin.
Kev tshawb fawb txog mob ntsws cancer tau pom tias:
Morphological thiab histological tsom xam ntawm lub ntsws qog nodules tau lees paub tias kev tiv thaiv kev kho mob nrog curcumin thiab quercetin induced apoptosis ntawm lub ntsws qog hlwb los ntawm modulating p53.
Xaus: Curcumin thiab quercetin muaj cov nyhuv synergistic, uas tuaj yeem cuam tshuam kev loj hlob ntawm cov qog hlwb los ntawm cov teebmeem ntawm kev txhawb nqa apoptosis thiab antiproliferation.
Puas yog quercetin muaj kev phiv?
Rau cov neeg laus feem ntau ntawm kev noj qab haus huv, quercetin muaj kev nyab xeeb rau kev siv me me (tsawg dua 1000 mg ib hnub rau 12 lub lis piam).
