So'nggi yillarda hujayra madaniyati texnologiyasi rivojlanmoqda va hujayra zavodlari. keng ko'lamli hujayra madaniyatida tobora ko'proq foydalanilmoqda, ular orasida muzlatilgan quritilgan jonli zaiflashtirilgan gepatit A vaktsinasi uning qo'llanilishi sohasining muhim tarmog'idir.
Gepatit A, gepatit A deb ataladi, gepatit A virusi (HAV) keltirib chiqaradigan o'tkir yuqumli kasallikdir. Klinik ko'rinishlari o'tkir boshlanadi, titroq, isitma, ishtahani yo'qotish, ko'ngil aynishi, charchash, gepatomegaliya va jigar faoliyatining anormalligi. Ba'zi hollarda sariqlik paydo bo'ladi va asemptomatik infektsiyalar ko'proq uchraydi va odatda surunkali va patogen tashuvchisi bo'lmaydi. Gepatit A vaktsinasi gepatit A ning oldini olish uchun ishlatiladigan vaktsina bo'lib, Xitoyda bolalar uchun asosiy vaktsinalardan biriga aylandi. 2008 yil may oyida u kengaytirilgan immunizatsiya vaktsinalaridan biriga kiritilgan. Ba'zi viloyatlar va shaharlar gepatit A ga qarshi bepul emlashni ta'minladilar.
Bozordagi gepatit A vaktsinalariga asosan inaktivlangan gepatit A vaktsinalari va jonli zaiflashtirilgan vaktsinalar kiradi, ular orasida muzlatilgan quritilgan jonli zaiflashtirilgan vaktsinalar hujayra zavodlarida qo'llaniladi. Liyofillangan jonli zaiflashtirilgan gepatit A vaktsina eritmasini ishlab chiqarishda har doim muammo bo'lgan va muzlatilgan quritilgan jonli zaiflashtirilgan gepatit A vaktsinasini tayyorlash uchun inson embrion o'pka diploid hujayralarini etishtirish uchun hujayra zavodlaridan foydalanish madaniyat maydonini tejashga, ifloslanish xavfini kamaytirishga yordam beradi. , va operatsiyalarni qisqartiring. Vaqtning afzalliklari va boshqa afzalliklarga ko'ra, uning ko'p qatlamli strukturasi dizayni gepatit A vaktsinasini ishlab chiqarishni sezilarli darajada yaxshilashi mumkin va asta-sekin rulonli shishani almashtirib, keng miqyosli ishlab chiqarish uchun hujayra madaniyatining yangi avlodiga aylandi. vaccines.
Bundan tashqari, hujayra zavodi standartlashtirilgan operatsiyalarda nisbatan kichik farqlar bilan aqlli ishlab chiqarishga erishish uchun avtomatlashtirilgan uskunalar bilan ham birlashtirilishi mumkin va JE, suvchechak va qizamiq kabi vaktsinalarni ishlab chiqarish uchun ham ishlatilishi mumkin.
The FAI climbed 5.9 percent year-on-year in the first 11 months of 2018, quickening from the 5.7-percent growth in Jan-Oct, the National Bureau of Statistics (NBS) said Friday in an online statement.
The key indicator of investment, dubbed a major growth driver, hit the bottom in August and has since started to rebound steadily.
In the face of emerging economic challenges home and abroad, China has stepped up efforts to stabilize investment, in particular rolling out measures to motivate private investors and channel funds into infrastructure.
Friday's data showed private investment, accounting for more than 60 percent of the total FAI, expanded by a brisk 8.7 percent.
NBS spokesperson Mao Shengyong said funds into weak economic links registered rapid increases as investment in environmental protection and agriculture jumped 42 percent and 12.5 percent respectively, much faster than the average.
In breakdown, investment in high-tech and equipment manufacturing remained vigorous with 16.1-percent and 11.6-percent increases respectively in the first 11 months. Infrastructure investment gained 3.7 percent, staying flat. Investment in property development rose 9.7 percent, also unchanged.
