Kufulumizitsa matenda odalirika

Kuzindikira matenda opatsirana mochedwa zimaika anthu ambiri pachiwopsezo padziko lonse lapansi, makamaka ndi matenda opatsirana ndi nyama ndi anthu. Pafupifupi 75% ya matenda 30 atsopano omwe apezeka mwa anthu omwe adalembedwa m'zaka 30 zapitazi mu 2008 ndi ochokera ku nyama, malinga ndi lipoti la WHO lomwe linatulutsidwa mu 2021.

"Gulu lathu ladzipereka kuthana ndi mavuto opanga matenda kuti likwaniritse zosowa za matenda kuti POCT ifulumire komanso kuti anthu azitha kupeza mosavuta matenda a IVD onse awiri (mkati mwa galasi") ndi omwe si a IVD," akutero Lianyi Xie, yemwe adayambitsa Hangzhou Bigfish Bio-tech Co., Ltd, mu 2017. "Mayeso athu osamalira odwala (POCT) adapangidwa kuti azigwira ntchito mwachangu m'malo omwe alibe zinthu zambiri, pomwe akuthandiza mitundu yosiyanasiyana ya matenda."

Ma POCT a Bigfish adapangidwa kuti ateteze chitetezo cha chakudya, komanso thanzi la ziweto ndi nyama zina, makamaka poganizira kuchuluka kwa eni ziweto ku China.

Kuvomerezedwa mwachangu kwa mapangidwe a POCT, Xie anafotokoza, kuyenera kukhala bwino pakati pa luso ndi kuyang'ana kwambiri pa ukadaulo wachikhalidwe komanso wodalirika wowonjezera mphamvu, kutengera polymerase chain reaction (PCR), kuti azindikire kuchuluka kwa ma nucleic acids kuchokera kuzinthu zovuta.

Taganizirani za kufalikira kwa matenda a nkhumba ku Africa (ASF) ku China, komwe kuli msika waukulu kwambiri padziko lonse lapansi wopanga ndi kugwiritsa ntchito nkhumba. Mu 2019, ASF inapha nkhumba zoposa 43 miliyoni, ndipo inataya pafupifupi $US 111 biliyoni. Kupanga mapulani a POCT mwachangu kumadalira mgwirizano wapafupi ndi mabungwe ophunzira ndi aboma, komanso mayankho ochokera kwa ogwiritsa ntchito, monga obereketsa nkhumba akuluakulu ku China.

"Kulondola ndi kuzindikira komwe kulipo mofanana ndi malo ochitira kafukufuku, ngakhale m'mafamu ang'onoang'ono akutali, ndikofunikira kwambiri pa zida zathu, zomwe zimapangidwa kuti zikhale zotsika mtengo komanso zosavuta kugwiritsa ntchito pa mbusa aliyense wa nkhumba," akufotokoza Xie.

Ntchito ya Bigfish yoletsa ndi kuthetsa matenda m'dziko lonselo imakhudzanso matenda a brucellosis, omwe akadali matenda ofala kwambiri padziko lonse lapansi, komanso matenda omwe amapezeka mwa nyama zina.

Bigfish yathandiza POCT mwachangu m'malo osungira ziweto pafupifupi 4,000 ku China. Shuilin Zhu, wapampando wa Zhejiang Small Animal Protection Association, adawonjezera kuti ukadaulo wa kampaniyo pa zinyama

Kusamalira ziweto sikunangowonjezera mphamvu yopewera ndi kuwongolera ziweto, komanso kunathandizanso kwambiri ubwino wa ziweto.

Kulola kapangidwe kakang'ono kopanda mtengo waukulu kwa ogwiritsa ntchito ndi chinthu china chofunika kwambiri pakupanga ndi kupanga mayeso awo a majini. Kuyesa kwawo kwa mamolekyulu a GeNext sikuli kwakukulu kuposa botolo la madzi, ndipo kumalemera makilogalamu awiri. Ili ndi ma mesofluidic ndi microfluidic chips omwe amasintha njira zovuta kuyambira pakutulutsa nucleic acid, kukulitsa majini mpaka kuyika deta nthawi yeniyeni ndikusanthula.

GeNext 2.0 yomwe ikugwiritsidwa ntchito popanga zinthu zambiri ingathandize kuti kuchuluka kwa zitsanzo kukwere kuchoka pa 1 mpaka 16 pa kuzungulira kulikonse, ndipo kuchuluka kwa zitsanzozo kukuwonjezeka kuchoka pa 5 mpaka 25 pa kuzungulira kulikonse, popanda nthawi yowonjezera kapena ndalama zina.

"Mapangidwe athu a GeNext 3.0 adzachepetsanso nthawi, adzasintha ndi ma chips ochokera ku silicon, ndipo adzaphatikiza ukadaulo wotsatizana monga kutsatizana kwa nanopore kuti pakhale nkhani yayikulu yachipatala poyesa ana asanabadwe komanso kuzindikira khansa msanga," akutero Xie. "Mapangidwe athu a POCT tsiku lina angagwiritsidwe ntchito ndi aliyense, kulikonse popanda kuganizira mtengo wake."
