Objective: To analyze the lens opacity of some hospitals in Hangzhou to provide evidence for further improvement of radiation protection. Methods: Physical examination data of 1720 radiological workers who underwent occupational disease physical examination in our hospital on January1, 2016and December 31, 2017 were collected. Lens turbidity, gender, age, type of work, radiological working age and other influencing factors were statistically analyzed, and logistic regression analysis was used for multipactor analysis. Results: A total of 112 cases of lens turbidity (turbidity rate 6.51%) , after lens turbidity, subcapsular majority (64 cases (57.14%) ) ; lens turbidity increased with age, and showed an increasing trend of radiation working age; the lens turbidity rate was different in different types of work, including nuclear medicine (23.33%) 、radiology (6.76%) 、interventional radiology (6.06%) 、dental radiology (4.26%) and radiotherapy (4.21%) . Type of work、age and length of service are risk factors for lens opacity; Age and type of work were independent risk factors for lens opacity. Conclusion The turbidity of lens of radiologcial workers is related to age and workering age. Radiological workers engaged in nuclear medicine should strictly strengthen radiation protection.

Objective: To understand the quality of life and influencing factors of patients with pneumoconiosis, and to provide a basis for formulating targeted improvement strategies to improve the quality of life. Methods: From April to December 2018, Questionnaire survey was conducted on patients with pneumoconiosis that diagnosed in Hangzhou Hospital for the Prevention and Treatment of Occupational Disease, using self-made questionnaire and SF-36.237 valid questionnaires were used to investigate the basic conditions, health services, social assistance and quality of life of patients, and analyze the influencing factors of quality of life. Results: Hangzhou city's some pneumoconiosis patients were mostly with monthly income <3000 yuan (72.6%, 172/237) ; more patients with medical expenses of 8000 to 25000 yuan per year (60.3%, 143/237) ; The proportion of patients receiving medical assistance and work-related injury insurance was low, at 2.1% (5/237) and 23.8% (54/227) respectively. The scores of Pneumoconiosis patients in PhysicalFunction (PF) , Role-Physical (RP) , Bodily Pain (BP) , General Health (GH) , Vitality (VT) , Social Function (SF) , Role-Emotional (RE) and Mental Health (MH) were lower than the national norm (P<0.05) . The scores from high to low were BP, SF, MH, PF, VT, RE, RP and GH. There were significant differences in the quality of life scores of pneumoconiosis patients with different ages, work types, education levels and monthly income (P<0.05) . Conclusion The quality of life of some patients with pneumoconiosis in Hangzhou is lower than that of the general population. Age, work types, and monthly income are factors influencing quality of life.
