ABSTRACT
Objective To retrospectively analyze the prevention and control effect and epidemic characteristics of elderly tuberculosis in Hubei Province from 2016 to 2020, and to provide a scientific basis for the prevention and treatment of elderly tuberculosis in Hubei Province． Methods The data on tuberculosis patients aged 60 and above who registered their current address in Hubei Province from 2016 to 2020 were collected and analyzed. The registration rates and composition ratios were analyzed using χ2 test and χ2 test for trend. Results A total of 135 976 tuberculosis patients were reported in Hubei from 2016 to 2020. The annual average registration rate of elderly tuberculosis among the elderly registered residence population (referring to the registration rate of elderly registered residence population aged 60 and above as the denominator, and tuberculosis patients aged 60 and above as the numerator) was 263.51/100 000. The highest rate was 300.02/100,000 in 2017, and the lowest was 188.19/100,000 in 2020 (χ2=70,227.603, P2trend=40.448，P2trend=740.911, P2trend=380.557, P2trend=323.764, P<0.001). Conclusion The elderly population with pulmonary tuberculosis in Hubei Province shows a downward trend. It is necessary to focus on the efforts of designated hospitals to proactively identify cases, increase the proportion of confirmed cases, maintain a high tracking in place, reduce medical delays, and ensure the effectiveness of tuberculosis prevention and treatment for the elderly.
ABSTRACT
SD rats aged 4 weeks were fed the diets containing high level of selenium(5.68 mg/kg),rich level of selenium(0.73mg/ kg)and(or)high level of Cadmium(33.3 mg/kg).The rats were sacrified at the end of 3,6,9 or 12 weeks after exposure to study the effects of high levels of selenium and cadmium fed to rats on contents of selenium in blood,heart,liver,kidneys,lung,brain and spleen.The results showed that the Contents of selenium in blood and tissues,especially in liver and kidney,were decreased significantly in the rats fed high levels of selenium and cadmium simultaneously in compared with those fed high level of selenium alone.This indicated that the development of endemic selenosis might be affected by cadmium in the area rich in high levels of selenium and cadmium.
