Tib neeg elastin feem ntau yog synthesized los ntawm lig embryonic mus rau thaum ntxov neonatal lub sij hawm, thiab yuav luag tsis muaj tshiab elastin yog tsim thaum lub sij hawm laus. Elastic fibers tau hloov pauv txawv thaum lub sij hawm endogenous laus thiab photoaging.
1. Poj niam los txiv neej thiab txawv lub cev
Thaum ntxov 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 feem ntawm tib neeg lub cev.
Qhia tias daim tawv nqaij elasticity yog qhov sib txawv ntawm qhov sib txawv; thaum tseem tsis muaj qhov sib txawv tseem ceeb ntawm cov poj niam txiv neej sib txawv
Daim tawv nqaij elasticity maj mam txo nrog lub hnub nyoog.
2. Hnub nyoog
Nrog rau lub hnub nyoog nce, cov tawv nqaij laus endogenous tsis tshua elastic thiab pliable dua cov tawv nqaij hluas, thiab cov elastic fiber network so thiab poob, manifesting raws li daim tawv nqaij flattening thiab nplua wrinkles; Nyob rau hauv endogenous laus, tsis tsuas yog fibrous Degradation ntawm ECM Cheebtsam, tab sis kuj poob ntawm ib co oligosaccharide fragments. LTBP-2, LTBP-3, thiab LOXL-1 yog tag nrho cov kev tswj hwm, thiab LTBP-2 thiab LOXL-1 ua lub luag haujlwm tseem ceeb hauv kev tswj thiab tswj cov fibrin deposition, sib dhos, thiab cov qauv los ntawm kev khi fibulin-5. Perturbations txuam nrog kev qhia tawm tshwm sim raws li cov txheej txheem kom nce endogenous aging.
3. Cov xwm txheej ib puag ncig
Kev puas tsuaj ntawm ib puag ncig ntawm daim tawv nqaij, feem ntau yog kev yees duab, huab cua paug thiab lwm yam tseem ceeb tau maj mam them rau, tab sis cov txiaj ntsig kev tshawb fawb tsis zoo.
Photoaging daim tawv nqaij yog tus cwj pwm los ntawm ob qho tib si catabolic thiab anabolic remodeling thiab transformation. Cov tawv nqaij zoo li ntxhib thiab tawv tawv heev vim tsis tsuas yog poob ntawm fibrillin-nplua nuj microfibrils ntawm lub epidermis-dermal hlws ris, elastin degeneration, tab sis tseem ceeb tshaj, mus rau lub deposition ntawm chaotic elastin tshuaj nyob rau hauv lub sib sib zog nqus dermis, kev ua ntawm elastin cuam tshuam.
Cov qauv kev puas tsuaj rau cov elastic fibers ntawm daim tawv nqaij yog irreversible ua ntej lub hnub nyoog ntawm 18 xyoo, thiab UV tiv thaiv yog ib qho tseem ceeb thaum lub sij hawm kev loj hlob theem. Tej zaum yuav muaj ob lub tswv yim ntawm lub hnub ci fiber ntau: elastic fibers yog degraded los ntawm elastase secreted los ntawm ib puag ncig cov hlwb los yog irradiated los ntawm UV, thiab elastic fibers yog khoov thaum lub sij hawm synthesis txheej txheem; fibroblasts muaj cov nyhuv ntawm kev txhawb nqa elastic fibers kom muaj linearity. Cov nyhuv yuav qaug zog, ua rau khoov.—— Yinmou Dong
Cov txheej txheem hloov ntawm daim tawv nqaij elasticity yuav tsis pom tseeb txaus rau qhov muag liab qab, thiab peb tuaj yeem siv cov kws tshaj lijdaim tawv nqaij diagnostic analyzersaib thiab txawm kwv yees qhov kev hloov pauv yav tom ntej ntawm daim tawv nqaij.
Piv txwv li,ISEMECO or Resur Skin Analyzer, nrog kev pab ntawm kev teeb pom kev zoo thiab lub koob yees duab siab kom nyeem cov ntaub ntawv ntawm daim tawv nqaij, ua ke nrog AI tsom xam algorithm, tuaj yeem soj ntsuam cov ntsiab lus thiab kev kwv yees ntawm cov tawv nqaij hloov.
