Objective To investigate the prevalence of hypertension in high temperature,noise operators and related factors.Methods A total of 1 263 workers from a steel enterprise were selected,among them,583 operators contacting with high temperature and noise served as the group A,267 operators only contacting with noise as the group B,249 operators only contacting with high temperature as the group C and 164 operators without contacting with high temperature and noise as group D.The prevalence of hypertension and related factors were analyzed.Results In the analysis of hypertension prevalence rate,the group D (12.8％) ＜ group C (25.7％)＜ group B (34.6％)＜group A(43.9％).In the analysis of blood pressure(systolic pressure/diastolic pressure),the group D[(115.8± 11.5)/(73.6±5.4) mm Hg]＜ group C[(124.1±10.7)/(81.9±7.3) mm Hg]＜ group B[(132.9±11.3)/(86.7±5.2) rnm Hg]＜ group A [(143.7 ± 12.8)/(92.4 ± 6.5) mm Hg].The onset age of hypertension in the group A was earlier than that in the group B,C,D (P＜0.05).The lower educational level,the more working years,the bigger body mass index(BMI),themore smoking and drinking were,the higher the hypertension prevalence rate was.Hypertension had significantly negative correlation with the educational level and significantly positive correlation with age,working years,BMI,smoking and drinking (P＜ 0.05).Conclusion The prevalence of hypertension in high temperature and noise operators is related to personal constitution and living habits.

Objective To investigate the influence of supplemental probiotics on the changes of immunity and microecology in asthmatic children. Methods One hundred and seventy?six asthmatic children treated in the Affiliated Hospital of North China University of Science and Technology from October 2015 to October 2016 were selected in the study and were randomly divided into two groups, 88 cases in each group. Patients in the control group were given routine treatment, and the observation group was treated with routine treatment combined with probiotics. The changes in immune index and microecological index before and after the treatment were compared between the two groups. Results After treatment, the observation showed CD3+ was(65. 8±2. 6)％,CD4+was(39. 2±1. 3)％,CD8+ was(24. 5±1. 0)％,CD4+/CD8+ was(1. 6±0. 2),NK cells was(15.2±0.4)％,Th1/ Th2 was(5.7±1.3),interferon γ was(56.3±1.8)ng/L,bifidobacterium was (9. 3±0. 7)lgCFU/g,lactobacillus was(9. 5±0. 6)lgCFU/g,yeast was(6. 6±0. 8)lgCFU/g,compared with those before treatment ((52. 5±1. 7)％,(23. 6±0. 8)％,(19. 7±0. 9)％,(1. 2±0. 1),(12. 8±0. 3)％,(3. 4±0. 7), (44.0±1.5)ng/L,(4.2±1.1)lgCFU/g,(4.9±0.4)lgCFU/g,(3.7±0.4)lgCFU/g),the differences were statistically significant ( t= 5. 533, 9. 957, 5. 436, 6. 332, 4. 875, 9. 764, 5. 727, 15. 143, 12. 387, 10. 837, P<0. 05).
