Vim yog qhov kev tiv thaiv no, txawm tias cov tshuaj siv rau mob qog noj ntshav (chemotherapy) tsis tuaj yeem ncav cuag cov hlwb qog noj ntshav hauv lub hlwb. Tab sis tam sim no cov kws tshawb fawb tau pom ib qho kev daws teeb meem xav tsis thoob rau qhov no.
Qhov Kev Tiv Thaiv Ntshav-Lub Hlwb no yog dab tsi?
Hais yooj yim xwb, qhov no zoo li phab ntsa ruaj ntseg nyob ib puag ncig peb lub hlwb. Xav txog tias peb lub hlwb yog lub tsev tseem ceeb thiab ruaj ntseg tshaj plaws hauv lub tebchaws. Lub qhov rooj nkag mus rau hauv lub tsev ntawd yog los ntawm lub rooj vag ruaj khov heev. Lub rooj vag no tiv thaiv cov kab mob thiab cov tshuaj tsis xav tau hauv peb cov ntshav kom tsis txhob nkag mus rau hauv lub hlwb. Qhov no yog qhov peb hu ua Blood-Brain Barrier hauv kev kho mob.
Qhov kev tiv thaiv no yog qhov tseem ceeb rau peb. Tab sis qhov teeb meem yog, lub kaw lus tiv thaiv no kho txawm tias cov tshuaj chemotherapy ua 'cov qhua tsis xav tau' thiab tsis pub lawv nkag mus. Yog li, kev kho mob qog noj ntshav hauv hlwb tau dhau los ua qhov nyuaj rau cov kws kho mob.
Cov kws tshawb fawb txoj kev daws teeb meem tshiab: Ib qho me me implant uas yaj!
Ib pab kws tshawb fawb tau pom ib txoj kev daws teeb meem tshiab rau qhov teeb meem no: ib qho me me uas yaj hauv lub cev thiab muab tso rau hauv lub taub hau, ze rau qhov chaw ntawm lub hlwb qog.
Lub cuab yeej me me no, ib lub thawv me me dav li ib centimeter, yog ua los ntawm cov amino acid tshwj xeeb. Nws hu ua glycine . Qhov tshwj xeeb txog nws yog tias thaum muaj hluav taws xob me me rau nws, nws co thiab tso tawm cov suab nrov siab, lossis cov suab ultrasound , uas tsis hnov rau pob ntseg tib neeg. Cov txheej txheem no hu ua piezoelectric effect .
Tam sim no xav txog tias tus kws kho mob txhaj tshuaj tiv thaiv kab mob qog noj ntshav, xws li paclitaxel, rau hauv lub cev. Tib lub sijhawm, ib lub cuab yeej tswj hwm sab nraud muab hluav taws xob rau qhov me me ntawm lub hlwb. Tom qab ntawd, cov nthwv dej ultrasound uas nws tso tawm ua rau cov hlwb ntawm Blood-Brain Barrier uas peb tau tham txog co me ntsis, tsim cov qhov me me ntawm lawv. Yog tias xav kom meej, nws zoo li lub rooj vag kaw nruj qhib me ntsis. Los ntawm cov qhov sib txawv ntawd, cov tshuaj mob qog noj ntshav tuaj yeem mus ncaj qha rau cov hlwb qog noj ntshav. Nws puas zoo kawg nkaus?
Cia peb saib qee qhov zoo ntawm cov thev naus laus zis tshiab no hauv lub rooj hauv qab no.
| Feature | Kev piav qhia |
|---|---|
| Lub hom phiaj | Cov tshuaj no raug xa mus rau cov hlwb qog nqaij hlav ncaj qha. |
| Kev Nyab Xeeb | Tsis ua rau cov nqaij ntawm lub hlwb noj qab nyob zoo puas tsuaj. |
| Khoom siv | Ua los ntawm glycine, uas muaj txiaj ntsig zoo rau lub cev. |
| Cov khoom lwj tau | Raws li lub sijhawm dhau mus, nws yuav yaj mus rau hauv lub cev yam tsis ua rau muaj kev phom sij. Tsis tas yuav phais dua kom tshem nws tawm. |
| Kev Tswj | Cov kws kho mob tuaj yeem tswj tau tias lub cuab yeej no yuav tsum ua haujlwm ntev npaum li cas. |
Kev siv tshuab ultrasound ntau heev
Cov thev naus laus zis ultrasound no tsis yog ib yam tshiab rau kev kho mob. Peb tau hnov txog nws rau kev luam theej menyuam yaus. Tab sis tam sim no nws tau siv rau ntau dua li ntawd. Raws li Dr. Neal Kassell, ib tus kws tshaj lij tom qab cov thev naus laus zis, nws zoo li "siv lub iav tsom iav los tsom lub hnub lub teeb thiab hlawv nplooj." Qhov ntawd txhais tau tias lub zog tuaj yeem raug coj mus rau qhov tseeb heev, tsuas yog mus rau lub hom phiaj xav tau. Yog li nws tsis ua rau cov nqaij noj qab haus huv nyob ib puag ncig puas tsuaj.
Cov kws kho mob tam sim no paub ntau dua 30 txoj kev sib txawv los cuam tshuam nrog cov ntaub so ntswg siv cov thev naus laus zis ultrasound, piv rau tsuas yog 5 txoj kev ib xyoo caum dhau los.
Nrog rau qhov kev paub no, vam tias cov thev naus laus zis no tuaj yeem siv los kho tsis yog mob qog noj ntshav hauv lub hlwb xwb, tab sis kuj tseem muaj cov kab mob neurological xws li Alzheimer's thiab Parkinson's, mob qog noj ntshav pancreatic thiab prostate uas nyuaj kho, thiab txawm tias kev quav yeeb quav tshuaj.
Yav tom ntej ntawm cov thev naus laus zis no yuav zoo li cas?
Peb yuav tsum nco ntsoov tias qhov no tseem nyob rau theem kev tshawb fawb. Cov kws tshawb fawb tau sim qhov no rau ntawm nas thiab tau pom cov txiaj ntsig zoo heev. Thaum muab cov tshuaj, cov qog nqaij hlav me me thiab cov tsiaj lub neej ntev ob npaug. Txawm tias tom qab 6 lub hlis, tsis muaj kev phiv tshwm sim. Tom ntej no, pab pawg neeg npaj yuav sim nws txoj kev nyab xeeb thiab kev ua haujlwm zoo hauv npua.
Tus kws tshawb fawb tseem ceeb uas tau tshawb pom qhov no, Thanh Nguyen, vam tias yuav tsim ib yam dab tsi zoo li daim ntaub uas muaj ntau yam khoom me me no yav tom ntej. Tom qab ntawd nws yuav ua tau los tsom thiab kho ntau qhov ntawm lub hlwb ib zaug. Tej zaum txoj kev no yuav siv tau los rhuav tshem cov hlwb qog nqaij hlav uas tseem tshuav tom qab lub qog nqaij hlav hauv hlwb raug phais tshem tawm.
Cov Lus Qhia Txog Kev Coj Mus Tsev
