RESUMEN
Objective To analysis contraindication detection of radiological workers and explore thevariation trend. Methods Occupational health examination data of radiological workers were selected from 2014 to 2018. Contraindications were identified according to the criteria, and the detection rates and trends were described in each statistical dimension. Results A total of 17197 cases were selected. Among them 74 patients were found contraindication and the detection rate is 0.43%. The major abnormalities were in thyroid gland and crystalline lens; The detection rate of female is higher than that of male (χ2 = 25.24，P < 0.01); High age andhigh working age groups showed a higherrate of contraindication detection; The abnormal rate of contraindication increased with the age; The risk of > 30 working years group is 2.541 times that of 1 ～5 working years group (95%CI: 1.32 ～4.88). The abnormal rate of thyroid grand was increased year by year, and the trend test showed statistical significance (χ2 = 3.87，P < 0.05). Conclusion Low dose ionizing radiation has a great effect on thyroid gland and crystalline lens of radiation workers, whichhigh age and high working years group should be pay attention to. The contents of occupational health monitoring should be further regulated to safeguard the health of radiation workers so that we can discover the possible health effects and take intervention earlier.
RESUMEN
<p><b>OBJECTIVE</b>To explore the relationship between nonalcoholic fatty liver disease (NAFLD) and the incidence of type 2 diabetes mellitus (T2DM) in Chinese adults.</p><p><b>METHODS</b>A total of 4847 Chinese adults were enrolled in this prospective study. All participants underwent physical examination at one of three hospitals in Nanjing during 2008. According to results from B ultrasound, the participants were grouped according to NAFLD diagnosis, with 1468 in the NAFLD group and 3379 in the control group.Participants were followed up until diagnosis of T2DM or for 4 years. The cumulative incidence rates of T2DM were calculated for and compared between the NAFLD group and the control group. The relationship between NAFLD and risk of T2DM was examined by Cox proportional hazards modeling.</p><p><b>RESULTS</b>During the 4-year follow-up,387 (8.0%) of the patients were diagnosed with T2DM. The cumulative incidence rates of T2DM in the NAFLD group and the control group were 17.2% and 4.0%, respectively. After adjusting for age,sex,body mass index,blood pressure,triglyceride level and alanine aminotransferase level, NAFLD was found to be closely related to the incidence of T2DM (relative risk:3.465,95% confidence interval:2.755-4.358).</p><p><b>CONCLUSION</b>NAFLD is associated with elevated risk of T2DM in adult patients in Nanjing,China. The general population of this region may benefit from focused public health intervention and treatment strategies targeting to prevent development of T2DM in conjunction with NAFLD.</p>
