Objective To investigate the relationship between sense of organizational justice,future self-continuity and job burnout among state-owned enterprise employees in communication industry,analyze the mediating role of future self-continuity. Methods The convenience sampling method was adopted to select 1 262 employees in state-owned communication enterprises in first-tier cities,new first-tier cities[hereinafter referred to as "（new） first-tier cities"] and fifth-tier cities from February to March 2022. The data were collected by the demographic data questionnaire,job burnout questionnaire,sense of organizational justice scale,self-others integration scale,and the data were analyzed. Results Among the surveyed employees,male,middle managers and managers had the highest scores of future self-continuity and sense of organizational justice,and the lowest scores of job burnout. The job burnout was significantly negatively correlated with future self-continuity and sense of organizational justice（r=-0.446,-0.518,both P<0.01）,and future self-continuity was significantly positively correlated with sense of organizational justice（r=0.453,P<0.01）. The future self-continuity played a partial intermediary role in the impact of organizational justice on job burnout,the intermediary effect was 0.121,accounting for 23.09% of the total effect. The city type had a moderating effect on the prediction of organizational justice on future self-continuity（Moderated mediation index 95%CI:-0.099 0--0.000 4）. The moderating effect wasmarginal significant（the result of the interaction between organizational justice and city type was t=1.951,95%CI:-0.001-0.363,P>0.05）. The employees' organizational justice in（new） first-tier cities had a greater impact on future self-continuity（Bsimple=0.883,P<0.01,95%CI:0.740-1.025）,while employees' organizational justice in fifth-tier cities had a smaller impact on future self-continuity（Bsimple=0.702,P<0.01,95%CI:0.588-0.816）. The scores of future self-continuity,perceived organizational justice and job burnou in employees in（new） first-tier cities were （5.28±0.98）,（4.06±0.55） and （2.59±0.89）points,respectively. The employees in fifth-tier cities had lower scores of future self-continuity[（5.12±0.93）points],perceived organizational justice[（4.02±0.53）points],and higher scores of job burnout[（2.71±0.91）points]. Conclusions The organizational justice and future self-continuity are important influencing factors of job burnout among employees in state-owned communication enterprises,and future self-continuity plays a partial mediating role between them. The city type moderates the predictive effect of organizational justice on future self-continuity. Improving the sense of organizational justice is conducive to improving their future self-continuity and reducing their level of job burnout.

Objective To understand the overall situation of peripheral blood cell count of radiation workers under long-term low-dose ionizing radiation,so as to provide basis for improving radiation protection measures and ensuring occupational health of radiation workers. Methods A total of 1 307 radiation workers in Jiangsu Province in 2021 were selected as the research subjects. According to different post status,gender,age,working age,nature and rank of work unit,the overall situation of peripheral blood cell of radiation workers was compared and analyzed. Results Among 1 307 radiation workers in Jiangsu Province in 2021,number of workers with on-the-job health examination was the largest（85.5%）,while the number of workers with pre-job（7.2%） and off-post（7.3%） health examination was the smallest. The number of white blood cell count（WBC）,lymphocyte count（LYM） and neutrophil count（NEU） of the off-post radiation workers were the lowest,while those of the pre-job radiation workers were the highest,and the differences among the three groups were statistically significant（F=10.025,20.618,3.111,all P<0.01）. Among the on-the-job radiation workers,the level of WBC in females was lower than that in males（F=5.408,P<0.01）,and WBC abnormality rate was higher than that in males（χ²=3.980,P<0.05）. There was statistically significant difference in WBC among different age groups（F=6.914,P<0.01）,and the WBC was the lowest among workers aged 41-<51 years old. There was statistically significant difference in WBC among different working-age groups（F=4.982,P<0.01）,and the WBC in workers with 21-<31 years of working-age was the lowest. Among white blood cell classification count,the difference in decreased neutrophils（NEU） was statistically significant among different working-age groups. The level of WBC of radiological workers in nuclear power industry was lower than that of medical radiological workers（P<0.05）,mainly decreased neutrophils. Among medical radiological workers,the level of WBC in provincial hospitals was the lowest,while that in district hospitals was the highest（F=22.388,P<0.01）. Conclusions Among 1 307 radiation workers in Jiangsu Province in 2021,the long-term low-dose ionizing radiation affect white blood cell classification count levels,and WBC of radiation workers in nuclear power industry is lower than that of medical radiation workers. The workers who are female,senior working age,engaged in nuclear power industry and provincial hospitals are more likely to have lower occupational WBC. So daily management and radiation protection of these people should be further strengthened.

Objective To analyze the individual dose monitoring level of radiologists in a medical institution of Jining City from 2017-2021,provide support for targeted health education for radiation personnel. Methods The thermoluminescence dose equipment was used to monitor the individual dose of occupational external exposure of radiation workers. The radiation workers in a medical institution of Jining City from 2017-2021 were selected as the survey objects,to analyze the individual dose monitoring results in five consecutive years. Results From 2017 to 2021,totally 1 685 radiation workers were monitored,and the annual collective effective dose of all radiation workers was 1 608.12 mSv,the annual effective dose per capita was 0.95 mSv. There was no person whose annual effective dose per capita exceeded 5 mSv/a. There was statistically significant difference in annual effective dose per capita among different years（H=4.168,P<0.01）. The individual annual effective dose in 2021 was the highest,which was 1.70 mSv. The individual annual effective dose in ≥5 years of working age group was higher than that in <5 years of working age group,while the individual annual effective dose in 10-<20 and ≥20 years of working age groups was higher than that in 5-<10 years of working age group,and the differences were statistically significant（P<0.01）. There was statistically significant difference in the individual annual effective dose among different occupational categories（H=187.603,P<0.01）. The individual annual effective dose of nuclear medicine workers was the highest（1.06 msv）. Conclusions From 2017 to 2021,the personal dose of radiation workers in a medical institution of Jining City is at lower level,and and the management of radiation protection should focus on nuclear medicine,the age group ≥50 years old and ≥5 years of working age group. For interventional radiologists,it is recommended that the ophthalmic lens dose monitoring should be carried out in combination with the actual situation. For nuclear medicine personnel,especially who is exposed to ¹³¹I,it is recommended that the internal exposure monitoring should be taken to more accurately evaluate personal dose.

Objective To study the antioxidant capacity of camel milk powder from a brand in Xinjiang in different seasons. Methods The different batches of 2020 camel milk powder purchased in January 2021 were divided into groups according to the season,and dissolved with the appropriate proportion. The antioxidant capacity was detected by chemical model method. The oxidation and degradation ability of lipid was measured by thiobarbituric acid method,free radical scavenging ability was measured by superoxide anion scavenging method,and reducing ability was measured by ferric reduction ability plasma assay （FRAP）. Results In the ratio of oil∶camel milk powder solution=1∶1 group,the oxidation inhibition rate of camel milk powder content 25% mixed group had the highest oxidation inhibition rate,and in the ratio of oil∶camel milk powder solution=1∶3 group,the oxidation inhibition rate of camel milk powder content 25% summer group had the highest oxidation inhibition rate（all P<0.05）. When the content of camel milk powder was dissolved at 14.29%,the superoxide anion clearance rate of summer camel milk powder was lower than that of winter camel milk powder and mixed camel milk powder（both P<0.05）,and there were no statistically significant differences in the superoxide anion clearance rate of the other three groups（content was 50%,25% and 11.11%）（all P>0.05）. When the content of camel milk powder was 25% dissolved,the iron ion reduction ability of the mixed camel milk powder was the strongest,when the content of camel milk powder was 14.29% dissolved,the iron ion reduction ability of the mixed camel milk powder was the strongest,when the content of camel milk powder was 11.11% dissolved,the iron reduction ability of winter camel milk powder was strong（all P<0.05）. Conclusions The camel milk powder has certain antioxidant activity,and the antioxidant capacity of mixed camel milk powder is stronger. There is no statistically significant difference in antioxidant capacity between summer and winter camel milk powder. The inhibition rate of lipid oxidation is related to the concentration of milk powder,however,its antioxidant capacity is affected by many factors,such as sample quality,detection method and region.
