RESUMEN
Objective To study the trends of lung cancer mortality among adult residents in Macheng City, Hubei Province from 1984 to 2018． Methods Mortality data was extracted from Macheng City disease surveillance points (DSPs) system and China Demographic Yearbook. The age-period-cohort (APC) model and Intrinsic Estimator algorithm were used to estimate the age effect, period effect and cohort effect of lung cancer mortality. Results The age effect coefficient of lung cancer mortality increased with age from 20 to 74 years old. The mortality risk of the 70-74 group was 42.62 times that of the 20-24 group. The period effect coefficient of lung cancer mortality also continued to rise with time. The cohort effect coefficient was parabolic, and residents born in 1939-1943 had the highest coefficient (1.298 4). Conclusion The risk of lung cancer death of adult residents in Macheng City significantly increased with the year and the rapid development of socio-economics.
RESUMEN
AIM: To explore the influence of processing with fresh-scorpion on element contents in crude scorpion in order to elucidate the processing method. METHODS: Macro-elements Ca,Mg and trace-elements Fe,Cu,Zn and Pb in crude scorpion were determined with emission spectrometric method. RESULTS: Contents of Ca,Mg in live-scorpion group were obviously lower than that in commercial-scorpion(P0.05). CONCLUSION: Processing with live-scorpion has obviously advantage over one with commercial scorpion on element contents.
