Tib neeg elastin feem ntau yog tsim los ntawm lub sijhawm embryonic lig mus rau lub sijhawm yug menyuam thaum ntxov, thiab yuav luag tsis muaj elastin tshiab tsim tawm thaum lub sijhawm laus. Cov fibers elastic dhau los ua ntau yam kev hloov pauv thaum lub sijhawm laus endogenous thiab photoaging.
1. Txiv neej thiab poj niam thiab ntau yam ntawm lub cev
Txij li xyoo 1990, qee cov kws tshawb fawb tau sim 33 tus neeg ua haujlwm pab dawb los kawm txog qhov elasticity ntawm daim tawv nqaij hauv 11 qhov ntawm tib neeg lub cev.
Qhia tau tias daim tawv nqaij elasticity sib txawv ntawm ntau qhov sib txawv; thaum tsis muaj qhov sib txawv ntawm ntau tus poj niam txiv neej sib txawv
Cov tawv nqaij elasticity maj mam txo qis nrog hnub nyoog.
2. Hnub nyoog
Nrog rau hnub nyoog nce ntxiv, cov tawv nqaij laus endogenous tsis tshua muaj zog thiab pliable dua li cov tawv nqaij hluas dua, thiab cov elastic fiber network tawg thiab poob qis, qhia ua daim tawv nqaij flattening thiab wrinkles zoo; hauv endogenous laus, tsis yog tsuas yog fibrous Degradation ntawm ECM Cheebtsam, tab sis kuj poob ntawm qee qhov oligosaccharide fragments. LTBP-2, LTBP-3, thiab LOXL-1 tau raug tswj hwm tag nrho, thiab LTBP-2 thiab LOXL-1 ua lub luag haujlwm tseem ceeb hauv kev tswj hwm thiab tswj hwm fibrin deposition, sib dhos, thiab cov qauv los ntawm kev khi fibulin-5. Perturbations cuam tshuam nrog kev qhia tawm cov yam ntxwv tshwm sim ua cov txheej txheem los ua kom endogenous laus.
3. Tej yam ib puag ncig
Kev puas tsuaj ntawm ib puag ncig rau daim tawv nqaij, feem ntau yog photoaging, pa phem thiab lwm yam tau maj mam raug them sai sai, tab sis cov txiaj ntsig tshawb fawb tsis yog qhov system.
Daim tawv nqaij laus zuj zus yog tus yam ntxwv los ntawm kev hloov pauv catabolic thiab anabolic. Daim tawv nqaij zoo li ntxhib thiab ntsws tob vim tsis yog tsuas yog poob cov microfibrils nplua nuj ntawm qhov epidermis-dermal junction, elastin degeneration, tab sis qhov tseem ceeb tshaj, rau kev tso cov tshuaj elastin chaotic hauv cov dermis tob, kev ua haujlwm ntawm elastin cuam tshuam.
Qhov kev puas tsuaj rau cov qauv ntawm cov tawv nqaij elastic yog qhov tsis rov qab ua ntej hnub nyoog 18 xyoo, thiab kev tiv thaiv UV yog qhov tseem ceeb thaum lub sijhawm loj hlob. Tej zaum yuav muaj ob txoj hauv kev ntawm lub hnub ci elastic fiber: cov elastic fibers raug rhuav tshem los ntawm elastase secreted los ntawm cov hlwb nyob ib puag ncig lossis irradiated los ntawm UV, thiab cov elastic fibers raug khoov thaum lub sijhawm synthesis; fibroblasts muaj cov nyhuv ntawm kev txhawb nqa cov elastic fibers kom tswj tau linearity. Cov nyhuv ua rau qaug zog, ua rau khoov.—— Yinmou Dong
Cov txheej txheem hloov pauv ntawm daim tawv nqaij elasticity tej zaum yuav tsis pom tseeb txaus rau lub qhov muag liab qab, thiab peb tuaj yeem siv cov kws tshaj lijlub tshuab kuaj mob tawv nqaijsoj ntsuam thiab txawm tias kwv yees qhov kev hloov pauv yav tom ntej ntawm daim tawv nqaij.
Piv txwv li,ISEMECO or Resur Skin Analyzer, nrog kev pab los ntawm kev teeb pom kev zoo thiab lub koob yees duab siab txhais los nyeem cov ntaub ntawv ntawm daim tawv nqaij, ua ke nrog AI kev tshuaj xyuas algorithm, tuaj yeem saib cov ntsiab lus thiab kev kwv yees ntawm kev hloov pauv ntawm daim tawv nqaij.
