Abstract:
Objective To study the differences in levels of plasma cytokine profiles including interleukin-6 (IL-6),interleukin-10 (IL-10),tumor necrosis factor-alpha (TNF-alpha) and C-reactive protein (CRP) between healthy controls and people with smoking and alcohol drinking behaviors at different ages,and to investigate the correlation of plasma cytokine profiles with age,smoking and alcohol drinking behaviors.Methods The concentrations of IL-6,IL-10,TNF-alpha and CRP in 350 healthy volunteers,60 cigarette smokers and 65 people with smoking and alcohol drinking behaviors were detected by ELISA.All subjects were grouped by age,gender,smoking and alcohol drinking behavior.The differences in the levels of plasma cytokine profiles among groups were analyzed by statistics software SPSS18.0.Results The concentrations of IL-6 and CRP in 25-39years,40-49 years,50-59 years and over 60 years groups were (1.1±0.7) ng/L,(1.5±0.1) ng/L,(1.7±0.2) ng/L,(2.1±0.1) ng/L and (3.1±1.0) mg/L,(4.4±±0.6) mg/L,(6.2±1.7) mg/L,(8.0±0.8) mg/L,respectively.The concentrations of IL-6 and CRP were significantly increased with age (F=1.60,7.50,P=0.012,0.043),while the concentrations of IL-10 and TNF-alpha were not correlated with age (F=4.20,4.80,P=0.178,0.421).There were no significant differences in the concentrations of IL-6,IL-10,TNF alpha and CRP between males and females (P＞0.05).The plasma CRP level was higher in smoking group than in control group [(6.8±0.6) mg/L vs.(3.1± 0.4) mg/L] and was highest in smoking-alcohol group [(9.5±0.5) mg/L vs.(6.8±0.6) mg/L,(3.1±0.4) mg/L,F=8.40,P=0.046].Compared with the control group,IL-6 level was increased and IL-10 level was decreased in smoking group and smoking-alcohol group.There were no significant differences in levels of IL-6,IL-10 and TNF-a among the three groups (F=2.90,4.30,4.80,P=0.089,0.672,1.231).Conclusions The plasma levels of IL-6 and CRP are significantly increased with age,but the plasma levels of IL-10 and TNF-a have no correlations with age.The plasma levels of IL-6,IL-10,TNF-a and CRP are not affected by gender.CRP level is significantly influenced by smoking and alcohol drinking behaviors,which should be taken into consideration to establish the reference values.
