Peb delve rau hauv ntau txoj kev, lawv qhov zoo thiab qhov tsis zoo, thiab cov lus qhia yav tom ntej hauv kev tshawb fawb.

Cheap Localized Drug Delivery for Cancer: Ib Qhov Kev Pom Zoo

Kev kho mob qog noj ntshav yog kim, thiab kev kho mob feem ntau tuaj nrog kev mob tshwm sim tsis zoo. Kev tshawb nrhiav rau kev kho mob qog noj ntshav pheej yig dua thiab ua tau zoo dua tau ua rau muaj kev nce qib tseem ceeb hauv kev xa tshuaj hauv zos. Txoj hauv kev no yog tsom mus rau cov tshuaj noj ncaj qha rau ntawm qhov chaw qog, txo qis qhov kis tau rau cov ntaub so ntswg noj qab haus huv thiab txo tus nqi tag nrho ntawm kev kho mob los ntawm kev xav tau koob tshuaj tsawg. Kab lus no yuav tshawb txog ntau yam tswv yim kom ua tiav pheej yig localized tshuaj xa rau mob qog noj ntshav, tshuaj xyuas lawv cov kev ua tau zoo, cov kev txwv, thiab lub peev xwm rau kev txhim kho yav tom ntej. Peb kuj tseem yuav xav txog lub luag haujlwm tseem ceeb ntawm cov chaw tshawb fawb xws li cov Shandong Baofa Cancer Research Institute hauv kev nce qib no.

Methods rau Localized Drug Delivery

Targeted Nanoparticles

Nanoparticles yog tsim los nqa cov tshuaj kho mob ncaj qha rau cov qog hlwb. Lawv qhov me me tso cai rau lawv nkag mus rau cov ntaub so ntswg thiab sib sau hauv cov qog. Lub hom phiaj kev xa tawm no txo ​​cov koob tshuaj uas xav tau, uas tuaj yeem txo cov nqi kho mob tag nrho. Ntau hom nanoparticles, suav nrog liposomes, polymeric nanoparticles, thiab inorganic nanoparticles, tab tom tshawb nrhiav. Cov yam ntxwv tshwj xeeb, xws li kev hloov kho saum npoo rau kev xa khoom thiab biodegradability rau kev nyab xeeb kev nyab xeeb, pab txhawb kev ua tau zoo thiab tus nqi-zoo ntawm txoj hauv kev no. Txoj kev loj hlob ntawm biodegradable nanoparticles yog ib qho tseem ceeb ntawm kev tshawb fawb lub hom phiaj los txo cov nqi mus sij hawm ntev thiab kev pheej hmoo cuam tshuam nrog cov tshuaj tsub zuj zuj hauv lub cev.

Microneedle Patches

Microneedle thaj ua rau thaj ua rau muaj kev mob thiab tsis tshua muaj kev cuam tshuam rau kev xa tshuaj. Cov koob me me no nkag mus rau ntawm daim tawv nqaij, xa tshuaj ncaj qha mus rau hauv dermis lossis cov ntaub so ntswg subcutaneous. Rau kev kho mob qog noj ntshav hauv zos, microneedle thaj ua rau thaj chaw uas muaj cov tshuaj tua kab mob lossis tshuaj tiv thaiv kab mob tau raug tshawb xyuas, tshwj xeeb tshaj yog rau cov qog nqaij hlav ntawm daim tawv nqaij. Txoj kev no tuaj yeem txo cov nqi cuam tshuam nrog kev tswj hwm, kev mus pw hauv tsev kho mob, thiab cov teeb meem ntawm cov txheej txheem txhaj tshuaj ib txwm muaj. Kev tshawb fawb ntxiv tsom mus rau kev txhim kho qhov tob tob thiab tswj cov tshuaj tso tawm ntawm thaj ua rau thaj no.

Focused Ultrasound

Focused ultrasound siv high-siv ultrasound nthwv dej rau permeabilize cell membranes, tso cai rau txhim khu kev xa cov tshuaj mus rau hauv cov ntaub so ntswg tsom. Ua ke nrog microbubbles, cov txheej txheem no, hu ua sonoporation, pab txhawb kev nkag mus ntawm cov tshuaj kho mob ncaj qha mus rau hauv cov qog nqaij hlav cancer, txhim kho kev kho mob zoo thiab muaj peev xwm txo cov kev xav tau ntau npaum li cas, pab txhawb ntau dua. pheej yig localized tshuaj xa rau mob qog noj ntshav. Thaum cov cuab yeej kim kim yuav tsum tau, nws lub peev xwm los txo qis cov kab mob toxicity thiab txo qhov kev xav tau ntau dua ua rau nws muaj txiaj ntsig zoo ntawm kev tshawb nrhiav rau kev kho mob qog noj ntshav kom raug nqi.

Kev txiav txim siab nqi thiab kev nyuaj

Thaum txoj kev xa khoom hauv zos tau cog lus rau kev txo nqi, ntau qhov kev sib tw tseem nyob. Kev txhim kho thiab tsim cov phiaj nanoparticles thiab microneedles tuaj yeem kim. Tsis tas li ntawd, kev kho mob txhais lus ntawm cov thev naus laus zis no yuav tsum muaj kev sim nruj thiab kev tswj hwm kev pom zoo, ntxiv rau tag nrho cov nqi. Txawm li cas los xij, cov peev nyiaj tau txais txiaj ntsig mus ntev los ntawm kev txo qis hauv tsev kho mob, tsawg dua cov kev mob tshwm sim, thiab cov txiaj ntsig kho tau zoo tuaj yeem tshaj qhov peev txheej pib. Kev txheeb xyuas tus nqi-cov txiaj ntsig zoo yog qhov tseem ceeb rau kev txiav txim siab tag nrho kev lag luam muaj txiaj ntsig ntawm qhov sib txawv pheej yig localized tshuaj xa rau mob qog noj ntshav txoj hauv kev.

Kev taw qhia yav tom ntej

Kev tshawb fawb yav tom ntej yuav tsom rau kev ua kom zoo dua cov txheej txheem uas twb muaj lawm thiab tsim cov tswv yim tshiab rau pheej yig localized tshuaj xa rau mob qog noj ntshav. Qhov no suav nrog kev txhim kho lub hom phiaj kev ua tau zoo, txhim kho cov khoom siv biodegradable, thiab kev koom ua ke cov txheej txheem zoo tshaj plaws rau kev xa tshuaj meej. Kev sib koom tes ntawm cov kws tshawb fawb, kws kho mob, thiab cov tuam txhab tshuaj yog qhov tseem ceeb los ua kom cov kev txhais lus ntawm cov kev nce qib no mus rau kev kho mob qog noj ntshav pheej yig thiab muaj txiaj ntsig zoo. Cov Shandong Baofa Cancer Research Institute, nrog rau nws txoj kev tsom mus rau kev tshawb fawb thiab kev tsim kho tshiab, ua lub luag haujlwm tseem ceeb hauv kev siv zog txuas mus ntxiv no.
