ABSTRACT

Objective To assess the prevalence of overweight and obesity among residents aged 35 years or older in Yuhuan county of Zhejiang Province and explore the associations of overweight and obesity with hypertension. Methods A cross-sectional study was conducted among 124 693 permanent residents aged 35 years or older, who were randomly selected using cluster sampling method from Yuhuan county. Results The prevalence of overweight and obesity was 34.53% and 10.18% among subjects, respectively. The overweight prevalence for male (35.56%) was higher than that for female (33.66%), whereas the obesity prevalence for female (11.26%) was higher than that for male (8.90%) (all P<0.05). The multivariate analysis showed that age, education, occupation, regular physical exercise, smoking, drinking and high-salt diet were possible factors for overweight and obesity (all P<0.05). After adjustment for covariates, compared to participants with normal weight, the multivariate logistic regression indicated that the adjusted odds ratio (OR) and their 95% confidential interval of overweight and obesity were 2.02 (95% CI:1.93-2.11) and 3.83 (95% CI:3.57-4.10) for hypertension in men, and were 1.94(95% CI:1.86-2.02)and 3.56(95% CI:3.35-3.77) in women, respectively. Conclusions The prevalence of overweight and obesity was high among residents aged 35 years or older in Yuhuan county, and they may relate to the increasing risk of hypertension.

ABSTRACT

Objective To evaluate the effect on the booster immunization of different dosage of hepatitis B vaccine among children and to provide suggestions for booster immunization.Methods Children aged 5 -1 4 years old were randomly selected who had received the primary immunization of hepatitis B vaccine under 1 year old but had not received the booster immunization in Yuhuan county.A total of 547 children received 5 μg hepatitis A and B combined vaccine boost immunization and 688 children received 1 0 μg hepatitis B vaccine boost immunization in 2009.The anti -HBs levels before and after the boost immunization were detected.Results The anti -HBs positive rates of children received 5 μg and 1 0 μg vaccine boost immunization were 97.81 % and 96.08% respectively and the positive rates in the antibody negative children were 94.78% and 93.62% respectively.While the Geometric Mean Titer (GMT) of anti -HBs were 1 433.1 8 mIU /mL and 21 1 1 .43 mIU /mL respectively,which were both significantly higher than those before the boost immunization (P <0.001 ).The increase of GMT of children received 1 0 μg hepatitis B vaccine was significantly higher than that of children received 5 μg hepatitis A and B combined vaccine (P <0.05).Conclusion Both dosages of hepatitis B vaccine booster immunization are effective for children aged 5 -1 4 years old and 1 0 μg hepatitis B vaccine boost immunization has the better effect.

ABSTRACT

Objective To study the efficiency of booster immunization with different recombinant hepatitis B vaccines.Methods 2789 children aged over 10 years who had completed the basic immunization of hepatitis B vaccine under 1 year old were selected.All the sampled children were classified into four groups (A,B,C and D) and immunized with different hepatitis B vaccines produced by different campanies respectively.Before booster immunization,their blood plasma specimens were detected for hepatitis B virus (HBV) surface antigen (HBsAg),antibodies to HBV surface antigen (anti-HBs) and antibodies to HBV core antigen (anti-HBc) by chemiluminescence.In each group,the anti-HBs positive children were immunized with one dosage and anti-HBs negative children were immunized three dosages of the same vaccine.Their blood specimens were collected again after 1 month,and detected for anti-HBs.Results The anti-HBs positive rates of A,B,C and D group were 36.43%,37.59%,42.91% and 46.46% respectively before immunization while 89.20%,91.52%,90.96% and 85.45% respectively after immunization with one dosage,99.12%,99.47%,98.87% and 98.85% respectively after immunization with three dosages.The differences of anti-HBs positive rates in the four respective groups showed statistical significances between any two rates of pre-immunization,post-immunization with one dosage and post- immunization with three dosages (all P<0.05).The anti-HBs positive conversion rates of four groups were 83.01%,86.41%,84.16% and 72.82% respectively after immunization with one dosage.The anti-HBs positive conversion rate of four groups were 98.62%,99.16%,98.03% and 97.84% respectively after immunization with three dosages and the difference of positive conversion rates in each group showed statistical significances between booster immunization with one dosage and booster immunization with three dosages.The average GMTs in anti-HBs positive children in the four groups were 2853.21,6254.23,3581.40 and 3021.32 mIU/ml respectively after immunization with one dosage.The average GMTs of anti-HBs negative children in the four groups were 273.08,648.52,387.87 and 245.36 mIU/ml respectively after immunization with one dosage,and were 632.30,2341.14,563.97 and 394.08 mIU/ml respectively after immunization with three dosages.Conclusion Our data showed that it would be suitable to anyone to use the four vaccines for anti-HBs positive children aged over 10 years with one dosage and for anti-HBs negative children aged over 10 years with three dosage booster immunization.

ABSTRACT

This study was aimed to investigate the effects of peripheral blood Th17 cells, IL-17 and IL-21 in the occurrence and development of acute leukemia. 60 patients with acute leukemia (19 patients with ALL, 41 patients with AML) were divided into non-remission group (group A, n=24), remission group (group B, n=36); 25 healthy volunteers were used as control group (group C). In addition to this, these 60 patients were divided into infection group (n=32) and non-infection group (n=28) on the basis of infection status. The concentration of IL-17 and IL-21 in the peripheral blood mononuclear cell culture supernatant after stimulation with anti-CD3 and anti-CD28 mAb were determined with ELISA. The expression of CD4+ IL-17+ cells was determined by flow cytometry. The results showed that (1) the concentrations of IL-17 and IL-21, and proportion of Th17 cells in group A and group B were much lower than those in group C (p<0.05); (2) the expression levels of IL-17 and IL-21, and the proportion of Th17 cells in group A were lower than those in group B (p<0.05); (3) the expression levels of Th17 and IL-17 in infection group were lower than those in non-infection group (p<0.05). It is concluded that Th17 cells may play important roles in the occurrence and development of acute leukemia through secreting IL-17 and IL-21, and their functional level can partially reflect the status of leukemia and can be used to evaluate the risks of infection in patients with leukemia.
