ABSTRACT
Objective To investigate pulmonary function of the children close to a large chemical industrial park and its influencing factors . Methods Date of daily average air PM10 ,SO2 and NO2 levels from two communities ( Area A near a chemical industrial area , area B far away from the chemical industrial area ) of Shanghai were collected .Questionnaires and pulmonary functions tests were performed among children of grade 3 to 5 in two primary schools from the two communities . Results The annual PM10 levels were 75.12 μg/m3 in area A and 79.46 μg/m3 in area B, which were both slightly higher than the secondary standard of Ambient Air Quality Standard, GB 3095-2012 ( 70 μg/m3 ) .The annual NO 2 level (40.67μg/m3)in area B was slightly higher than the secondary standard of Ambient Air Quality Standard, GB 3095-2012(40 μg/m3).There were no significant differences in PM10, SO2 and NO2 levels between the two communities .The height and some pulmonary functions parameters such as forced vital capacity ( FVC) and forced expiratory volume in one second ( FEV1 ) of children in are A were lower than those in area B.After reference predicted values of lung function were balanced , there were no significant differences in children's pulmonary function parameters between the two areas , FVC% and FEV1% were both above 87%, FEF50% and FEF75% were both above 72%.Bad condition of the ventilation in the kitchen and passive smoking had adverse effects on FEV 1%or FVC%and FEF50%%(r about -0.1). Conclusion The air quality close to the large chemical industrial park was not so bad , and there is no significant differences in the children's pulmonary function between area A and area B .The children's pulmonary may be more sensitive to the indoor environment in the low levels of atmosphere pollution .
ABSTRACT
@#BACKGROUND: This study aimed to investigate the epidemiological and clinical characteristics of patients with heat-related il ness, and guide the prevention, diagnosis and treatment of heat-related il ness. METHODS: From June 2013 to August 2013, seventy patients with heat-related illness were treated at Jinshan Hospital of Fudan University, and their epidemiological characteristics, laboratory results, treatment and prognosis were retrospectively analyzed. RESULTS: In the 70 patients, 18 patients suffered from heat stroke and 52 patients from non-heat stroke. When the environmnent temperature was above 35 °C, the body temperature of the patients began to increase markedly. The patients with heat stroke were significantly older than those with non-heat stroke (P<0.05). The body temperature, heart rate, blood glucose, blood lactate dehydrogenase and blood creatine kinase in the patients with heat stroke were higher than those in the patients with non-heat stroke (P<0.05). Blood lactate dehydrogenase and blood creatine kinase were positively correlated with body temperature (r=0.801). CONCLUSION: When the environmental temperature goes above 35 °C, heat-related illness should be prevented, especially in the elderly. The body temperature, heart rate, blood glucose, blood lactate dehydrogenase and blood creatine kinase in patients with heat stroke are higher than those in patients with non-heat stroke. Blood lactate dehydrogenase and blood creatine kinase are positively correlated with body temperature, but their relationship with heat-related illness awaits further study.
