Kev Kho Mob Tus Nqi Ntawm Microneedling Hauv Cov Kab Mob thiab Cov Ncauj Regeneration

https://en.wikipedia.org/wiki/Microneedles

Kev nkag siab ntawm pej xeem feem ntau txuas microneedling rau kev zoo nkauj -tiv thaiv- kev laus, brightening. Txawm li cas los xij, hauv cov tshuaj (qhov hnyav), nws ua lub luag haujlwm tseem ceeb dua, muab cov kev daws teeb meem tshiab rau kev kho mob thiab cov ntaub so ntswg rov ua dua tshiab, nrog rau kev sib raug zoo muaj txiaj ntsig ntau tshaj li kev lag luam "kev zoo nkauj."

Mob mobsawv cev rau qhov tsis txaus ntseeg txog kev noj qab haus huv thoob ntiaj teb. Kev cuam tshuam txog ~ 40 lab tus tib neeg (mob ntshav qab zib ko taw rwj, mob siab, venous ceg ulcers), lawv raug nqi txhua xyoo ntau tshaj $ 10 billion USD. Cov kab mob no nyob rau hauv lub inflammatory theem, tsis muaj angiogenesis thiab loj hlob yam. Ib txwm debridement muaj cov txiaj ntsig tsawg; biologics siab heev yog tus nqi - txwv tsis pub. Microneedling muab ib qho tshwj xeeb dual -txoj kev daws teeb meem:lub cev stimulation + tshuaj xa.

Lub cev, microchannels qhib platelets, tso PDGF thiab TGF-, uas nrhiav cov fibroblasts thiab macrophages los pib kho. Kev tswj hwm micro- raug mob ua rau muaj qhov ua kom tsis muaj menyuam nyob hauv zos, pab ua kom "kho qhov tsis zoo." Cov qauv nas qhia pom qhov dawb paug microneedle kev kho mob nrawm nrawm kaw los ntawm ~ 35% tiv thaiv kev tswj hwm.

Pharmacologically, microneedles xa VEGF, EGF, thiab lwm yam proteins zoo sib sib zog nqus rau hauv lub qhov txhab. Siv cov tshuaj pleev ib ce, cov macromolecules no sai sai degraded los ntawm proteases hauv qhov txhab exudate; microneedling bypasses txoj kev degradation no. Cov kev tshawb fawb soj ntsuam siv VEGF-loaded thaj ua rau thaj chaw mob ntshav qab zib ko taw tau ua tiav 72% ua tiav qhov kaw hauv 12 lub lis piam, piv rau 44% nrog kev saib xyuas tus qauv.

Hauvkev tswj caws pliav, microneedling excels. Hypertrophic scars and keloids involve hyperactive fibroblasts and aberrant collagen. Microneedles physically disrupt disorganized collagen bundles while delivering antifibrotics (triamcinolone, 5-FU), achieving "disruption-reconstruction." Patients typically see >50% caws pliav flattening tom qab 3-5 zaug, nrog qis rov tshwm sim dua li kev txhaj tshuaj ib leeg.

Raualopecia, cuam tshuam ntau pua lab, microneedling muaj ib txoj hauv kev tsis yog -pharmacological. Scalp needling ua rau kom cov ntshav ntws hauv zos thiab ua kom cov kab mob follicular. Ua ke nrog PRP lossis minoxidil, cov plaub hau dav dav nce 20–30 plaub hau / cm² hauv rau lub hlis-ib txoj kev nyab xeeb rau cov tshuaj noj qhov ncauj.

Los ntawm qhov txhab mus rau caws pliav, tawv nqaij mus rau cov plaub hau, microneedling ua pov thawj nws tus kheej ntau dua li cov cuab yeej kho kom zoo nkauj - nws yog ib qho tseem ceeb uas qhib lub peev xwm ntawm cov tshuaj regenerative.
