Tiyeni tiphunzire za mayeso a NSOMBA (Fluorescence in Situ Hybridization) omwe amavumbula zinsinsi za majini anu!

Kodi munamvapo za 'kuyesa kwa NSOMBA' (Fluorescence in Situ Hybridization Test)? Mwina dokotala wanu wakupemphani kapena munthu wina amene mumamudziwa kuti muchite mayesowa. Ngakhale kuti zingamveke ngati zovuta pang'ono, ndi mayeso ofunikira kwambiri omwe amatha kuzindikira zinthu zambiri mkati mwa matupi athu. Chifukwa chake lero, tiyeni tikambirane za mayeso a NSOMBA awa, zomwe amachita, komanso momwe amachitikira m'njira yosavuta yomwe mungamvetse.

Kodi mayeso a NSOMBA (Fluorescence in Situ Hybridization) ndi chiyani?

Mwachidule, NSOMBA ndi mayeso a majini. Akatswiri a matenda, omwe ndi madokotala omwe ali akatswiri pozindikira matenda , amagwiritsa ntchito njira iyi kuzindikira matenda omwe amayamba chifukwa cha kusintha kwa zinthu zazing'ono zotchedwa ma chromosome m'thupi lathu. Nthawi zina, mayesowa angathandizenso kuzindikira kusintha kwa majini komwe kungachiritsidwe ndi matenda monga khansa.

Taganizirani izi motere: majini athu ali ngati buku la malangizo a matupi athu. Buku la malangizoli limatiuza momwe chilichonse m'thupi lathu chimagwirira ntchito. Majini amenewa amapezeka m'mapangidwe otchedwa ma chromosome, omwe ali ngati zingwe. Ndiye, chimachitika ndi chiyani ngati mawu ena m'buku la malangizoli, DNA yathu (deoxyribonucleic acid) , achotsedwa, kapena ngati pali mawu ambiri, kapena ngati mawu ena asinthidwa? Maselo athu alandira malangizo olakwika. Mwanjira imeneyi, chidziwitso chikhoza kutayika (kuchotsedwa), kukopedwa mopitirira muyeso (kukulitsa), kapena kusunthidwa (kusamukira). Kusintha kumeneku kungasinthe momwe matupi athu amagwirira ntchito ndikuyambitsa matenda monga khansa.

Kotero, chomwe mayeso a NSOMBA amachita ndichakuti, zili ngati kugwiritsa ntchito zolembera zamitundu yosiyanasiyana kuti "zikope" magawo enaake a ma chromosome kapena majini. Kenako, madokotala odziwa bwino ntchito amenewo amatha kupeza mosavuta magawo omwe amafunikira kuti adziwe matenda powayang'ana pansi pa maikulosikopu. Mukayang'ana mtundu uwu pansi pa maikulosikopu, umawoneka ngati magetsi amitundu yosiyanasiyana.

Kodi mayeso a FISH angadziwike ndi chiyani?

Ndiye mwina mukudzifunsa kuti, kodi ndi chiyani chomwe chingapezeke ndi mayeso a NSOMBA awa? Zinthu zazikulu ndi izi:

• Dziwani kusintha kwakukulu kwa majini mu khansa. Pogwiritsa ntchito izi, madokotala amatha kuzindikira mtundu wa khansa molondola ndikusankha chithandizo chabwino kwambiri.
• Yang'anani ngati pali vuto lililonse la chromosome mwana asanabadwe (woyembekezera) kapena atabadwa. Izi zimathandiza kuzindikira matenda ena a majini msanga.
• Kubereketsa mwana m'mimba mwa mayi (IVF) kumaphatikizapo kuyesa mwana wosabadwayo kuti awone ngati ali ndi vuto la chromosome asanaikidwe m'chiberekero cha mayi (kuyesa majini asanaikidwe m'chiberekero).

Kodi mayeso a NSOMBA awa amagwira ntchito bwanji?

Chabwino, tsopano tiyeni tiwone chinsinsi chaching'ono chokhudza momwe mayeso a NSOMBA amagwirira ntchito.

Ndanena kale kuti DNA yathu ili ngati buku lalikulu la malangizo. Chifukwa chake mayeso a NSOMBA awa ali ngati kuwonetsa mbali zofunika kwambiri za buku la malangizo ndi utoto wapadera wa fluorescent. Asayansi amapanga "utoto wopaka utoto," kapena "chofufuzira," pomangirira zilembo za fluorescent ku DNA yokha.

DNA yathu imapangidwa ndi zingwe ziwiri zomwe zimagwirizana, monga mano a zipper. Zimene asayansi amachita ndi izi, choyamba amalekanitsa zingwe ziwirizi pogwiritsa ntchito probe yomwe adapanga, ndi DNA yomwe ili mu chitsanzo chomwe akufuna kuyesa. Amapanga probe iyi kuti igwirizane ndi DNA yomwe akufuna, ndiko kuti, chiganizo chenicheni chomwe akufuna m'buku la malangizo.

Kenako, amasakaniza ma probe okonzedwa awa ndi chitsanzo cha DNA chotengedwa kuchokera ku minofu ya thupi kapena madzi (izi zimatchedwa cholinga). Kenako, ngati probe imeneyo ikapita ndikupeza chidutswa cha DNA chomwe chili ndi mawu omwe ikufuna, chimamatira (chosakanikirana). Chifukwa cha zilembo zowala zimenezo, chidutswa chimenecho cha DNA chidzawala ndi mtundu wokongola. Katswiri wa matenda akachiyang'ana ndi maikulosikopu yapadera, madontho owala awa adzawoneka bwino kwambiri. Kenako amatha kumvetsetsa ngati chidziwitso chofunikira chilipo komanso kuchuluka kwake. Kodi sizodabwitsa?

Kusintha kwa majini komwe kungadziwike poyesa nsomba

Akatswiri a matenda angagwiritse ntchito mayeso a FISH awa kuti aone ngati maselo ali ndi kusintha kwa majini komwe kumadziwika kuti kumayambitsa matenda monga khansa. Nthawi zina kungathandize kutsimikizira kapena kufotokoza bwino zotsatira za mayeso a karyotyping, omwe ndi mayeso a ma chromosome . Nazi zina mwa zosintha zomwe mayeso a FISH angapeze:

• Kukulitsa: Apa ndi pamene pali makope ambiri a jini kuposa momwe amayembekezera. Zili ngati kupanga kopi pomwe mukufuna kupanga kopi. Asayansi amatha kugwiritsa ntchito NSOMBA kuti aone kuchuluka kwa makope a jini kuposa momwe amayembekezera.
• Kusamutsa/kukonzanso: Apa ndi pamene gawo la jini kapena chromosome limasamutsidwira kumalo ena osati komwe liyenera kukhala. Asayansi amatha kugwiritsa ntchito ma probe awiri amitundu kuti azindikire izi. Mu jini yachibadwa, mitundu iwiri ya ma probe awa iyenera kuwoneka pafupi. Koma ngati malo asintha, mitundu iwiriyo idzawoneka yosiyana kwambiri.
• Kuchotsa: Monga momwe zinthu zimachitikira m'malo osiyanasiyana, asayansi amagwiritsa ntchito njira zofufuzira zingapo kuti apeze malo omwe palibe chidziwitso mu DNA. Njira zina zofufuzira zimamatira ku DNA yomwe ili mu chitsanzo, koma zina sizimatira komwe ziyenera kuchitikira. Pamenepo ndi pamene amadziwa kuti zina zatayika (zachotsedwa) pamalo amenewo.

Matenda omwe angapezeke poyesa nsomba

Madokotala angagwiritse ntchito mayeso a FISH kuti azindikire kusintha kwa majini komwe kungathandize kuzindikira matenda monga:

• Lymphoma
• Matenda a khansa ya m'magazi (acute myeloid leukemia), matenda a khansa ya m'magazi osatha (chronic myeloid leukemia), ndi matenda ena a m'magazi (leukemia).
• Myeloma yambiri
• Khansa ya chikhodzodzo
• Glioma (mtundu wa khansa ya muubongo)
• Mesothelioma (khansa ya m'mapapo)
• Kuwonjezeka kwa HER2 (izi zimawoneka kwambiri mu khansa ya m'mawere, komanso zitha kuwonekanso mu khansa ya m'mimba ndi m'mapapo)
• Kuwonjezeka kwa MET (izi zimawoneka kwambiri mu khansa ya m'mapapo, m'mimba, ndi m'mero)
• Kuwonjezeka kwa MYCN (mu mtundu wa khansa wotchedwa Neuroblastoma)
• Mu khansa ya m'mapapo yopanda maselo ang'onoang'ono , kusinthika/kusakanikirana kwa majini a ALK, RET, ndi ROS1 kumachitika. Majini awa a ALK, RET, kapena ROS1 amatha kuphatikizana ndi jini lina kuti ayambe khansa.

Kodi ndingakonzekere bwanji mayeso a FISH?

Momwe mumakonzekera mayeso a FISH zimadalira mtundu wa chitsanzo chomwe dokotala wanu akutengani.

• Pa kuyezetsa mwana asanabadwe: Dokotala wanu adzachita mayeso apadera otchedwa amniocentesis .
• Poyesa majini asanaikidwe m'mimba (PGD kapena PGS): Chitsanzo chaching'ono cha maselo ochokera m'mazira angapo chimatengedwa kuti chikayesedwe. Izi nthawi zambiri zimachitika masiku angapo pambuyo pa ovulation.
• Ngati dokotala wanu akukayikira kuti inu kapena mwana wanu muli ndi matenda omwe amayamba chifukwa cha kusintha kwa majini kapena kusintha kwa majini: Izi zitha kufufuzidwa ndi mayeso osavuta a magazi .
• Kuti mupeze khansa kapena kusintha kwa majini m'maselo a khansa (kuyesa maselo): Muyenera kuchitidwa biopsy (chotupa kapena mafupa biopsy) , yomwe ndi chitsanzo cha minofu kapena mafupa.
• Kuzindikira kapena kuyang'anira khansa ya chikhodzodzo: Nthawi zina mayeso a FISH amachitidwa pa mkodzo .

Mwa mayeso amenewa, biopsy yokha ndi yomwe imafuna kukonzekera kwapadera. Popeza biopsy zambiri zimachitika pansi pa anesthesia, muyenera kutsatira malangizo a dokotala wanu a momwe mungakonzekerere.

Kodi akatswiri a matenda a FISH amachita bwanji mayesowa?

Pa mayeso a FISH, katswiri wa matenda kapena katswiri wa labotale amatsatira njira izi:

1. Kupanga zofufuzira: Mu izi, amasankha zidutswa za DNA zomwe zikugwirizana ndi dongosolo la DNA lomwe akufuna. Kenako, amapanga zidutswa zazing'ono mu DNA imeneyo ndikuwonjezera zilembo za fluorescent.

2. Kuchepa kwa chofufuzira ndi cholinga: Izi zikutanthauza kulekanitsidwa kwa ma bond awiri pakati pa chofufuzira ndi chitsanzo cha DNA chomwe chikuyesedwa.

3. Kusakaniza: Pamene ma probe asakanizidwa ndi chitsanzo cha DNA chotengedwa kuchokera ku minofu ya thupi kapena madzi, ma probewo amalumikizana ndi ma DNA omwe akufuna.

4.Kuyang'ana zotsatira: Amagwiritsa ntchito maikulosikopu yapadera ya fluorescent kuti awone komwe zilembozo zikuwala mu chitsanzocho.

Katswiri wa matenda adzauza dokotala wanu zotsatira zake.

Kodi zotsatira za mayeso a FISH ndi ziti?

Mtundu wa zotsatira zomwe mumapeza kuchokera ku mayeso a FISH zimadalira mtundu wa mayeso omwe mwapeza. Kuyesedwa kwa FISH kotsimikizika kumatanthauza kuti pali vuto la chromosome kapena majini m'maselo omwe ali mu chitsanzocho. Ndi bwino kulankhula ndi dokotala wanu za momwe zotsatira zake zidzawonekere komanso tanthauzo lake.

Kodi chimachitika ndi chiyani ngati mayeso a FISH apezeka kuti ali ndi kachilomboka?

Ngati mayeso anu a FISH ali ndi kachilombo, dokotala wanu adzakufotokozerani tanthauzo lake komanso zomwe mungasankhe. Ngati mayesowo adachitika kuti apeze kusintha kwa majini mu khansa, pakhoza kukhala njira zina zochizira zomwe zimayang'ana kusintha komweko. Chifukwa chake ndikofunikira kulankhula ndi dokotala wanu popanda mantha.

Kodi zimatenga nthawi yayitali bwanji kuti mupeze zotsatira za mayeso a FISH?

Zingatenge sabata imodzi mpaka inayi kuti mupeze zotsatira za mayeso a FISH. Dokotala wanu adzakuuzani nthawi yoti muyembekezere zotsatira zake komanso momwe mungadziwire.

Ndiyenera kulankhula ndi dokotala wanga liti?

Ngati muli ndi mafunso okhudza mayeso kapena zotsatira zomwe mudalandira, musazengereze kulankhula ndi dokotala wanu. Adzakufotokozerani zonse.

Pomaliza, uthenga wofunika kwambiri

Kudikira zotsatira za mayeso a majini kungakhale koopsa, kodetsa nkhawa, ndipo nthawi zina ngakhale kotopetsa pang'ono. Mungakhale mukuyembekezera yankho. Mayeso a NSOMBA awa ndi ukadaulo womwe umakuthandizani kupeza mayankho amenewo, monga "highlighter" yomwe imapeza ndikusintha zidziwitso zomwe mukufuna .

Mayankho omwe mungapeze mwina sangakhale omwe mumayembekezera, koma adzakuthandizani kumvetsetsa momwe zinthu zilili komanso zomwe mungasankhe. Kuchokera pamenepo, inu ndi dokotala wanu mutha kugwira ntchito limodzi kuti mupange dongosolo labwino kwambiri lopitira patsogolo.

Kumbukirani, ndikofunikira kwambiri kufunsa dokotala wanu kuti akufotokozereni chilichonse chomwe mukuganiza chokhudza mayesowo, chifukwa chake akuchitika, komanso tanthauzo la zotsatira zake.

Kuyesa kwa nsomba, kuyesa majini, ma chromosome, DNA, khansa, kusintha kwa majini, kuyesa kwa mwana asanabadwe
