ABSTRACT
Objective To analyze the incidence of lung cancer in Qidong , Jiangsu Province of China from 1993 to 2012 . Methods The clinical data of lung cancer from 1993 to 2012 for patients with census registration in Qidong were sorted out from the cancer registration center in Qidong .The annual percent change ( APC) model was used to analyze the trend over time for the incidence of lung cancer .The SAS 9.4 software and the Joinpoint Regression Program 4.3.1.0 were used to implement data analyses . Results A total of 11 895 new cases of lung cancer were diagnosed in Qidong , Jiangsu province from 1993 to 2012 .Among them , 8 629 were male cases and 3 266 were female cases and the median age for these patients was 68 .41 .The crude incidence rate for lung cancer for males was 90 .06/100 000 , which was significantly higher than that for females, i.e., 29.94/100 000(Poisson distribution test, P<0.01). The standardized incidence rate of lung cancer for male was 52 .92/100 000 , which was significantly higher than that for females, i.e.18.52/100 000(Poisson distribution test, P<0.01).The APC for the crude incidence rate for lung cancer was 6 .1 from 1993 to 2012 and the APC for the standardized incidence rate for lung cancer was 5 .5 . Conclusion The incidence of lung cancer increases in Qidong on a yearly basis from 1993 to 2012, with the incidence thereof for males being significantly higher than that for females .
ABSTRACT
Zika virus was discovered in 1947 and was believed to be epidemic only in the Asia , Europe and Africa .However , in 2015 , the Zika virus was first spread to Brazil , and then to most other countries in Americas .Zika virus is a member of the Flaviviridae family and can be classified into the Asian lineage and the African lineage .Most Zika virus infections are asymptomatic ,but can be neurotropic or teratogenic ,giving rise to adult Guillain-Barre syndrome and neonatal microcephaly. Zika virus is primarily transmitted by mosquito-spread , besides , it can also be transmitted through blood transmission , sexual transmission ,and vertical transmission .At present , the most effective measure to prevent and control the spread of Zika virus is to control Aedes .No vaccines against Zika virus have appeared on the market so far .
