Txoj kev tshawb no tshawb xyuas qhov muaj peev xwm ntawm qhov sib npaug ntawm ob sab kab ke thib ob-dual nrhiav kom pom ob-dimensional comprehensive GC platform (GC × 2GC-MS / FID) rau metabolic profiling thiab fingerprinting ntawm nas tso zis.Cov qauv tau txais los ntawm tus qauv murine uas ua raws li kev noj zaub mov tsis zoo nyob sab hnub poob uas muaj cov rog thiab qab zib ntau (HFHS), uas ua rau rog rog, dyslipidemia, thiab insulin tsis kam.Cov zis tau sau los ntawm cov kauj ruam sib txawv ntawm txoj kev tshawb fawb tau siv los muab cov ntaub ntawv tseem ceeb thiab sib piv ntawm qhov muaj thiab cov txheeb ze faib tawm ntawm cov cim ntxov ntawm cov kab mob metabolic.Cov ntaub ntawv elaboration thiab kev txhais lus ua hauj lwm-flow muaj xws li ib tug advanced untargeted fingerprinting mus kom ze, nrog ncov-cheeb tsam nta kom nrhiav tau cov yam ntxwv tseem ceeb kom muaj nuj nqis los ntawm lwm tus qauv calibration.Qhov kev ntseeg siab ntawm kev luam ntiv tes tsis raug pom zoo tau lees paub los ntawm cov txiaj ntsig ntau ntawm cov yam ntxwv cuam tshuam uas pom feem pua ntawm kev hloov pauv raws li cov neeg pom los ntawm kev sib piv cov ntaub ntawv nyoos qu antitative descriptors (2D peak-thaj tsam ntim thiab feem pua ntawm cov lus teb).Cov tshuaj ntsuam xyuas uas tau tswj hwm nrog % ntawm qhov sib txawv ntawm 30 txog 1000, suav nrog pyruvic acid, glycerol, fructose, galactose, qabzib, lactic acid, mannitol thiab valine.Kev tswj hwm qis tau ua pov thawj rau malonic acid, succinic acid, alanine, glycine, thiab creatinine.Advanced fingerprinting kuj tau pom zoo rau kev ntsuam xyuas tus kheej cov kev hloov pauv hauv kev sim, yog li sawv cev rau cov cuab yeej cog lus rau kev tshawb fawb txog kev cuam tshuam tus kheej.Nyob rau hauv cov ntsiab lus no, nws yog qhov nthuav kom pom tias cov ntsiab lus uas tsis muaj kev ntxub ntxaug rau tag nrho cov pej xeem yuav cuam tshuam rau tib neeg.
