Is vacsaín chomhcheangailte bheo mhaolaithe é an vacsaín bhruitíneach a spreagann díolúine i gcoinne víreas na bruitíní, víreas an leicneach agus víreas na bruitíní deirge tar éis an vacsaínithe. Úsáidtear é chun an bhruitíneach, an leicneach agus an bhruitíneach dhearg a chosc. I dtáirgeadh mórscála na vacsaíne seo, is saothrán cille fíor-riachtanach é an Le dhá bhliain anuas, tá treocht anuas léirithe ag minicíocht na bruitíní i mo thír. In 2019, b’ionann líon na gcásanna den bhruitíneach i mo thír agus 2,974, b’ionann líon na mbásanna agus 0, agus thit an ráta minicíochta go 0.21/100,000. In 2020, ba é 856 líon carnach na gcásanna bruitíní i mo thír, ba é 0 an dola báis, agus thit an ráta minicíochta go 0.061/100,000. Bhí éifeacht choisctheach mhaith ag an vacsaín. Úsáideann táirgeadh ar scála mór vacsaín MMR go príomha monarcha cealla 40-ciseal. Dá mhéad sraitheanna, is mó cealla is féidir a ionaclú. Toisc go bhfuil líon na sraitheanna ró-ard, tá sé deacair oibriú. Go ginearálta, déantar oibríochtaí cosúil le beathú leachtach, meascadh cille, agus scaoileadh leacht le linn cultúir a bhaint amach trí chroithteoir uathoibrithe, rud a d'fhéadfadh earráidí de bharr fachtóirí daonna a laghdú freisin. . Trí líon na sraitheanna sa choimeádán a mhéadú, is féidir an limistéar cultúir a leathnú, agus tá ról tábhachtach aige in ullmhú táirgí bitheolaíocha.. agus cealla dioplóideacha daonna a ionaclú le tréithchineálacha caolaithe den víreas rubella. Cuir cobhsaitheoir oiriúnach leis agus reoite-triomaithe. Is comhlacht scaoilte cáis-daite é, atá oráiste-dearg nó leacht soiléir bándearg éadrom tar éis athdhéanta. Is iad príomh-chomhpháirteanna lyoprotectant ná albaimin dhaonna, geilitín agus siúcrós.
The measles vaccine is to inoculate chicken embryo cells with attenuated strains of measles virus and attenuated mumps virus respectively, and inoculate human diploid cells with attenuated strains of rubella virus. Add suitable stabilizer and freeze-dried. It is a cheese-colored loose body, which is orange-red or light pink clear liquid after reconstitution. The main components of lyoprotectant are human albumin, gelatin and sucrose.
In the past two years, the incidence of measles in my country has shown a downward trend. In 2019, the number of measles cases in my country was 2,974, the number of deaths was 0, and the incidence rate dropped to 0.21/100,000. In 2020, the cumulative number of measles cases in my country was 856, the death toll was 0, and the incidence rate dropped to 0.061/100,000. The vaccine has played a good preventive effect. The large-scale production of MMR vaccine mainly uses a 40-layer cell factory. The more layers, the more cells that can be inoculated. Because the number of layers is too high, it is difficult to operate. Generally, operations such as liquid feeding, cell mixing, and liquid discharging during culture are realized by means of an automated shaker, which can also reduce errors caused by human factors.
Cell factories are commonly used consumables for large-scale cell culture. By increasing the number of layers in the container, the culture area can be expanded, and it plays an important role in the preparation of biological products.
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.
