- 1. Mavuto Padziko Lonse a Khansa ya M'chiberekero ndi Kuyezetsa Matenda
Khansa ya pachibelekero ikadali vuto lalikulu padziko lonse lapansi pankhani ya thanzi la anthu, ngakhale kuti imatha kupewedwa kwambiri poyesa bwino komanso kuchitapo kanthu mwachangu. Malinga ndi bungwe la World Health Organization (WHO), milandu yatsopano yokwana 662,000 ndi imfa 349,000 zinachitika padziko lonse lapansi mu 2022, zomwe zaika khansa iyi ngati yachinayi yofala kwambiri komanso chifukwa chachinayi chachikulu cha imfa zokhudzana ndi khansa pakati pa akazi. Matendawa akupezeka kwambiri m'maiko osauka komanso apakati (LMICs), komwe kuchuluka kwa anthu omwe amafa ndi kuchuluka kwa anthu omwe ali ndi ndalama zambiri kumakhala kwakukulu kuposa m'malo omwe ali ndi ndalama zambiri. Izi zimachitika makamaka chifukwa chosowa mapulogalamu abwino kwambiri oyezetsa komanso kuzindikira bwino ndi kuchiza zilonda zomwe zisanachitike khansa, zomwe zimawonjezeka ndi:
-Zowunikira zomwe sizilipo kapena zofooka: Kusowa kwa ntchito zowunikira zomwe zikupezeka mosavuta komanso zotsimikizika.
-Zovuta pakugwiritsa ntchito zinthu: Zomangamanga zochepa za labotale, zinthu zoyendera pa intaneti, komanso magetsi odalirika.
-Kusowa kwa ogwira ntchitoKusowa kwa ogwira ntchito ophunzitsidwa bwino m'ma laboratori ndi m'zipatala.
-Kuchedwa ndi kutayika kwa zotsatira: Nthawi yochedwa pakati pa kusonkhanitsa zitsanzo ndi kupezeka kwa zotsatira, zomwe zimapangitsa kuti kuchedwa kwa chithandizo chamankhwala kuchedwe kapena kuti odwala asapezeke kuti atsatire [1].
2. Etiology ndi Maziko a Molecular of Cervical Carcinogenesis
Matenda osatha a papillomavirus ya anthu (HR-HPV) yomwe ili pachiwopsezo chachikulu ndi chifukwa chofunikira cha khansa ya pachibelekero. Pakati pa mitundu yoposa 200 ya HPV yomwe yadziwika, osacheperaMitundu 12Zagawidwa m'gulu la zinthu zomwe zimayambitsa khansa (Gulu 1) ndi International Agency for Research on Cancer (IARC).
Pa mulingo wa mamolekyulu, khansa yomwe imayambitsa HPV imayendetsedwa makamaka ndi ma virus oncoproteins E6 ndi E7. E6 imalimbikitsa kuwonongeka kwa puloteni yoletsa chotupa p53, pomwe E7 imagwira ntchito molimbika kuti puloteni ya retinoblastoma (Rb) isagwire ntchito, zomwe zimapangitsa kuti maselo asamayende bwino komanso kuti maselo asinthe molakwika.
3.Njira Zowunikira Zovomerezeka ndi WHO
Bungwe la World Health Organization limalimbikitsa kuyesa kwa HPV nucleic acid (NAT) ngati njira yoyamba yowunikira khansa ya pachibelekero.
Anthu ambiri:HPV DNA kapena mRNA-based NATs
Azimayi omwe ali ndi kachilombo ka HIV:Ma NAT ochokera ku HPV DNA
Nthawi zowunikira:
Akazi azaka zapakati pa 30 ndi 65: Zaka 5 mpaka 10 zilizonse
Azimayi omwe ali ndi kachilombo ka HIV: Zaka 3-5 zilizonse
Poyerekeza ndi njira zogwiritsira ntchito cytology, kuyezetsa HPV kumasonyezakukhudzidwa kwakukulundipo amaperekamtengo wapamwamba kwambiri woneneratu zoipa, zomwe zimathandiza kuti nthawi yowunikira ikhale yayitali komanso yotsika mtengo.
4.WHO Ikufuna Kuyesa Kuyeza HPV
Bungwe la WHO lapanga njira yodziwiraMbiri ya Zogulitsa Zolinga (TPP)pa mayeso oyesera a HPV omwe cholinga chake ndi kugwiritsidwa ntchito m'malo omwe ali ndi anthu ochepa komanso omwe alibe zinthu zambiri.[1]
Makhalidwe ofunikira ndi awa:
- Kugwirizana ndi zitsanzo zomwe zasonkhanitsidwa zokha
- Kuzindikira mitundu yambiri ya HPV yomwe ili pachiwopsezo chachikulu (mitundu ≥12)
- Ntchito yochitidwa ndi anthu osaphunzitsidwa ku labotale
- Zotsatira zimapezeka mkati mwa nthawi imodzi yokumana ndi dokotala
Mfundo zimenezi zimathandiza kuyezetsa malo osamalira odwala komanso njira zoyezera ndi kuchiza matenda.
5.Njira Yodziwira HPV Yokha Yokhala ndi Chiwopsezo Chachikulu
Dongosolo la Macro & Micro-Test la AIO800 limaperekanjira yogwirira ntchito yodziwikiratu yokha ya chitsanzokuphatikiza kuchotsa, kukulitsa, ndi kuzindikira nucleic acid mogwirizana ndi njira zowunikira zomwe bungwe la WHO limalimbikitsa.
5.1 Kayendedwe ka Ntchito Yoyeserera Yokha Yoyankha
Pulatifomuyi imagwirizanitsa kutulutsa, kukulitsa, ndi kuzindikira nucleic acid mu dongosolo limodzi lotsekedwa, zomwe zimafuna kuti wogwiritsa ntchito asamachitepo kanthu kwambiri. Kapangidwe kake:
- -Amachepetsa kudalira anthu ogwira ntchito zasayansi
- - Amachepetsa kusinthasintha kwa njira ndi chiopsezo cha kuipitsidwa
- - Imathandizira kutumizidwa m'malo osamalira anthu odwala m'malo ocheperako
Nthawi yomweyo, mphamvu yake yogwiritsira ntchito imathandizira kugwiritsidwa ntchito m'ma laboratories akuluakulu, zomwe zimathandiza mapulogalamu akuluakulu owunikira.
5.2 Kufalikira kwa Genotyping Yaikulu
Dongosololi limazindikira mitundu 14 ya HPV yomwe ili pachiwopsezo chachikulu, kuphatikiza mitundu yonse 12 yoyambitsa khansa yomwe yagawidwa ndi IARC (HPV16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, ndi 59), komanso HPV66 ndi HPV68.
Chofunika kwambiri, chimaperekamtundu wa majini enienizotsatira zake, zomwe zimathandiza kugawa zoopsa m'magulu ndi kuyang'anira bwino zachipatala.
5.3 Kuzindikira Kusanthula ndi Zotsatira Zachipatala
Ndi malire opezeka a makope 300/mL, dongosololi limatha kuzindikira matenda a HPV otsika omwe amayambitsa:
- - Kuzindikira msanga matenda okhudzana ndi matenda
- -Kusintha kwabwino kwa kuneneratu kolakwika
- - Chithandizo cha nthawi yayitali yowunikira
5.4 Chithandizo cha Kudziyesa Wekha
Nsanjayi imagwirizana ndi zonse ziwirizitsanzo za swab ya m'chiberekero ndi zitsanzo za mkodzo wodzisonkhanitsa wekhamogwirizana ndi malangizo a WHO kuti athetse zopinga zazikulu pakuyesa anthu, kuphatikizapo:
- -Kupeza malo ochepa oti munthu azitha kupeza chithandizo chamankhwala
- -Zoletsa za chikhalidwe cha anthu
