OBJECTIVE:
To investigate the possible effects of meteorological and environmental factors on allergic rhinitis of children.
METHOD:
Daily numbers of outpatients consulting general practitioners for AR between Jan 1 2007 and Dec 31 2011 were obtained from the Department of Otolaryngology-Head and Neck Surgery, Shanghai Children Medical Center. Daily maximum, average and minimum temperatures and humidity and wind power for Shanghai of the same 5 years were obtained from the Shanghai Meteorological Office. Air Quality data was provided by the Shanghai Municipal Environmental Protection Monitoring Center on daily SO2, NO2 and PM10, the average of O3 per 8 hours. The data was available as average values derived from the data of 6 state comtrolled monitoring stations distributed across Shanghai. Non-parametric generalized additive model (GAM) was used to analyze the highly non-linear or non-monotonic exposure-response relationship between meteorological and environmental factors and daily outpatient visiting for AR of children.
RESULT:
The daily numbers of AR children in outpatients department in this study were highest in the average daily temperature 11°C and 21°C. It showed two peak. But as the humidity increased, daily numbers of outpatients of AR children went down, indicating that the higy humidity has protective effect. Every 10 microg/m3 increase of environmental pollutants O3, SO2 and PM10 was linked to 1.95%, 1.19% and 0.33% increase in the number of visitors, respectively, suggesting the air pollution may increase the risk of onset of AR in children.
CONCLUSION
Meteorological and environmental factors have important effects on AR in children.

A dynamic study for the activity of myocardial cytochrome oxidase from guinea pigs fed with low selenium and low phospholipid semi-synthetic diet (basal diet) or diet supplemented with selenium, phospholipid or other agents was conducted with Pye Unicam SP-1800 UV spectrophotome-ter and Circular C100.The results showed that the activity of myocardial cytochrome oxidase from animals fed with basal diet was the lowest. The single supplement of selenium or phospholipids did not increase the enzymic activity significantly. Only when selenium and phospholipids, especially all the ingredients related to the phospholipids metabolism, such as choline and methionine were supplemented simultaneously, the enzymic activity (velocity constant K) then increased significantly, and sometime even exceeded that of the group fed with normal diet. In the sametime the ratio of phospholipids in heart and the cardiolipin content was close to that of control animals fed with normal diet. The significance of boundary lipids in heart for membranous enzyme and the pathogenesis of Keshan disease was discussed.

OBJECTIVE:
To investigate the impact of environment and message information for the treatment efficacy of children with allergic rhinitis (AR).
METHOD:
To choose 100 cases of children diagnosed with AR. The parents of children record daily symptom scores of AR of children everyday. While the doctors send the short message to the parents by using meteorological environment warning forecast technology to tell the parents the risk of AR attacks. We observe the morbidity of AR of the children and the treatment efficacy of children for 1 year. The 100 cases control group children diagnosed AR, their parents do not record daily symptom scores of AR and the doctors do not give the short message. We also observe the morbidity of AR of the control group children and the treatment efficacy of the children for 1 year.
RESULT:
The 100 cases intervention group children with AR, there are 11 cases refused to participate the group. We included a total 89 cases, 74 cases of children did a full year of intervention, 15 cases of children gave up. The control group 100 cases, nine cases refused to participate, 91 cases were included. The average episodes in the intervention group was 4. 67 times, the control group was 8. 12 times,--there were significant differences between the groups statistically. The execution rate on the prescribed clinic date in the intervention group visits was 91. 5%, while in the control. group, was only 67%. The compliance of parents of children to complete course of medication in the intervention group was 95. 6%, while the control group was 74.1%. Both sets of data are statistically significant differences. The children with sinusitis in intervention group was 26.97%, significantly lower than the 64.04% in the control group. The incidence in the intervention group and the control group of secretory otitis media was 8.99% and 6.60%, there was no statistically significant differences.
CONCLUSION
It can significantly increase the degree of attention of parents of children with AR that the parents of children record daily symptom scores of AR of children everyday, while the doctors send the short message to the parents by using meteorological environment warning forecast technology to tell the parents the risk of AR attacks. It can also improve the execution rate on the prescribed clinic date and improve compliance of parents of children to complete course of medication. It can significantly reduce seizure frequency and severity of episodes of AR, thereby improving the quality of life of children with AR, reduce the economic burden on families and society.

OBJECTIVE To investigate the possible effects of meteorological and environmental factors on IL-4 gene specific DNA methylation levels in CD4+T cells of children with AR.METHODS Thirty five pediatric AR patients(6-12 years) followed up for one year from the Department of Otolaryngology, Shanghai Children Medical Center from Jan, 1, 2012 to Dec. 31, 2012 were included in this study. Data on daily particulate matter of diameter smaller than 10 micrometer(PM10) and particulate matter of diameter smaller than 2.5 micrometer(PM2.5) was available as average values derived from the data of 6 state-controlled monitoring stations distributed across Pudong District, Shanghai. We quantified IL-4(interleukin-4) gene specific DNA methylation levels in CD4+T cells from 35 patients with AR and 30 healthy controls. mRNA levels of IL-4 gene were measured by real-time reverse transcriptase-PCR. Methods of personal exposure assessment of PM2.5 and PM10 were measured.RESULTS Compared with controls, IL-4 promoter region was hypomethylated in AR CD4+T cells(P=0.038). Of all observed CpG sites in IL-4 promoter region, there was significant differences in CpG-48, CpG+54(P=0.041, 0.032). IL-4 mRNA expression was significantly increased in CD4+T cells(P=0.039). The level of IL-4 mRNA expression was negatively correlated to the mean level of methylation in IL-4 promoter region. After adjusting, level of PM10 exposure was negatively correlated with level of methylation in IL-4 promoter region(r2=0.419,β=-0.470,SD=0.781,P=0.045). CONCLUSION Level of methylation in IL-4 promoter region may be affected by PM10 exposure.
