ABSTRACT
Objective To understand the Salmonella carrying situation among the employees of public places and dietetic in dustries in Chengdu railway area to enhance the health management among employees in catering and service industries and provide the basis for preventing the occurrence and outbreak of food poisoning.Methods The anal swab culture was adopted to perform the health carriage examination among the employees of public places and dietetic industries during 2011-2015.The isolated Salmonellas were identified by stereotyping and the relationship between Salmonella carrier state with seasons and years was analyzed.Results Among 86 971 detected samples,43 strains of Salmonella were detected with the detection rate of 0.49‰.Nineteen serotypes were identified,which were dominated by Salmonella derby,Salmonella Senftenberg and Salmonella typhimurium.The highest detection rate was in summer and autumn.Conclusion The stains types of Salmonella carried by employees in catering and service in dustries in Chengdu railway area were complex,and the detection rate was closely related to seasonal variation.It is needed to strengthen the health examination and prevent food poisoning occurrence.
ABSTRACT
Objective To investigate the prevalence rate of thyroid nodules as well as related influencing factors. Methods In this clinical study, 8,912 healthy people were included, involving medical staff, teachers, electric enterprise staff and civil authorities from January to December in 2014 . The prevalence rate of thyroid nodules and related influencing factors were investigated . Results (1) The prevalence rate of thyroid nodules was 40.4%, 34.9%for male and 46.7%for female. The prevalence of female was higher than that of male (P<0.001);(2) The prevalence rate of thyroid nodules showed a trend of increase with age (P<0.01);(3) The prevalence rate of thyroid nodules in medical staff and teachers was significantly higher than others (P<0.001);(4) The difference was statistically significant in BMI, blood pressure, blood lipid, blood glucose in thyroid nodule group and non thyroid nodules group (P<0.001). All indexes mentioned above of thyroid nodule group was much higher than those of non thyroid nodules group. (5) The prevalence rate of breast hyperplasia of females under the age of fifty years was significantly higher than those of non thyroid nodule group (P<0.001). Conclusion The prevalence rate of thyroid nodules is high. It is related to gender, age, occupation and estrogen. Effective measures should be taken to change people's bad habits, blood sugar control and blood pressure, reduce BMI and work tension in order to reduce the incidence of thyroid nodules.
ABSTRACT
Objective To investigate the levels of serum AFP and CEA in healthy physical examination people and their sexual difference.Methods (1 )Healthy physical examination people were divided into the group A(510 males)and group B(477 fe-males);(2)these two groups were subdivided into the group A1 (<40 years old),A2 (40 - <50 years old),A3 (50 - <60 years old),A4(60-<70 years old)and A5 (70 -87 years old),and group B1 (<40 years old),B2(40 -<50 years old),B3 (50 -<60 years old),B4(60-<70 years old)and B5(70-87 years old).The serum AFP and CEA in 987 healthy physical examination peo-ple were measured by the electrochemiluminesence immunoassay,and then the detection results were compared among various groups.Results (1)The detection results of serum AFP and CEA had statistically significant differences between the group A and B (P <0.01);(2)there was no statistical differences among the group A and among the group B.Conclusion The serum AFP and CEA levels in healthy physical examination people in the local area have difference between males and females,which in males are significantly higher than those in females,indicating that the reference range of AFP and CEA should be repectively established ac-cording to different sexes;while the serum AFP and CEA levels have no differences among various age groups in males and fe-males.
