Methods Age-period-cohort model was used to analyze changes in incidence and mortality of tuberculosis by age，period and cohort，and spatial statistical method was used to explore the spatial clustering of tuberculosis incidence and death. Results From 2005 to 2019，the incidence and mortality of pulmonary tuberculosis in China showed a decreasing trend year by year. The analysis results of age-period-cohort（APC） model showed that the incidence and mortality of pulmonary tuberculosis in Chinese people aged 10 years and older increased with age，and the incidence increased from 54.552/100 000 in the group aged 10-<15 years to 2 688.965/100 000 in the group aged ≥85 years（χ2trend=1495.365，P<0.01），the mortality rate increased from 0.063/100 000 in the 10-<15 year old group to 46.882/100 000 in the ≥85 years group（χ2trend=640.712，P<0.01）. Using 2010-2014 as the reference group，the rate ratio（RR） values of incidence and mortality of pulmonary tuberculosis among people aged 10 years and over in China showed a decreasing trend with the advance of time in 2005-2009 and 2015-2019. Using the 1965-1969 cohort as a reference，the RR for pulmonary tuberculosis incidence and mortality was significantly higher in those born before 1965 compared with those born after 1969，with increasing RR for incidence and mortality in those born 1934 and before，peaking in those born 1930-1934. Geographic information system（GIS） analysis results showed spatial clustering of tuberculosis incidence and death in China from 2005 to 2019，with Moran's Ⅰ>0 and Z>1.96，P<0.05. Local autocorrelation results showed that high tuberculosis incidence and mortality were concentrated in Xinjiang Uygur Autonomous Region and Xizang Autonomous Region，and low-low incidence was concentrated in the east and central regions. Conclusion Age-period-cohort is important factors affecting the incidence and mortality of tuberculosis，and there is a spatially clustering in the tuberculosis incidence and death. Therefore，it is necessary to increase screening of the elderly population，conduct tuberculosis knowledge campaigns，and increase the awareness rate of population health knowledge，while increasing economic aids in Xizang Autonomous Region and Xinjiang Uygur Autonomous Region to promote equity and accessibility in health resource allocation and protect population health.

Concentrations and health risks of mercury in aquatic products from the tributaries of Yongjiang in Guangxi Yantao HUANG, Shanfan LIANG, Yunyan FAN, Qiong TANG, Siyi CHEN, Shuting MENG OCCUPATION AND HEALTH    2025, 41 (23): 3209-3213.   Abstract （6）   HTML （3）    PDF （919KB）（2）       Knowledge map    Save Objective To understand the content of mercury in common freshwater fish and snails in aquatic products from the tributaries of Yongjiang in Guangxi，and to evaluate the health risks. Methods From August to December 2024，461 samples of 10 species of freshwater fish and snail were collected from two tributaries of the Yongjiang river in Guangxi Zhuang Autonomous Region. The mercury content in the edible parts of aquatic products was determined using the direct mercury analyzer method. The pollution level and health risk were evaluated using the single factor pollution index method and target hazard quotient，and the correlation analysis between mercury content and weight in some fish species was conducted. Results The highest content of mercury among the 11 aquatic products from the Yongjiang in Guangxi Zhuang Autonomous Region was topmouth culter，but the mercury content in all aquatic products did not exceed the standard. The single pollution index showed that 4.4% of silver carps and 100.0% of topmouth culters were mildly polluted by mercury，while the rest of the fish species were at normal background levels. The health risk assessment results indicate that the target hazard quotient for topmouth culters was greater than 1，while the target hazard quotients for the other ten types of aquatic products were less than 1. According to correlation analysis，it was found that there was a significant correlation between the levels of mercury and weight in the dorsal muscles of silver carp and mirror carp. Conclusion All aquatic products sourced from Yongjiang in Guangxi in this collected samples exhibited no instances of mercury exceeding safe limits，with the mercury contamination in the samples remaining at a relatively low level. With the exception of carnivorous fish like the predatory carp，the prolonged consumption of the remaining ten species of aquatic products from Yongjiang in Guangxi poses no significant risk to human health.

There was no statistically significant difference in age and body mass index（BMI） between the MTI group and the normal group（both P>0.05）,and warm-up before training was a factor affecting MTI（ P<0.05）. The highest proportion of injury sites was in the upper limbs,followed by the trunk,lower limbs,and head and neck. The highest proportion of injury types was soft tissue injury,followed by bone and joint injury,other injuries,and organ injury. In recent years,the proportion of soft tissue injury had gradually increased,while other injuries had relatively decreased. The highest proportion of injury training was physical training,followed by professional technical training,tactical training,and other common subjects. The highest proportion of injury causing factors was found in group training factors,followed by individual factors and environmental factors. Conclusion There are many influencing factors for MTI of officers and soldiers at high altitude,among which warm-up before training can effectively prevent their occurrence,and the prevalence rate of compulsory soldiers,college education,rural soldiers,Xizang and other regions,high training intensity is higher. In addition,the site of injury is concentrated in the upper limbs,with soft tissue injury as the main type of injury. The injury training is mostly physical training,and the injury factors are mostly group training factors. Reference | Related Articles | Metrics
