ABSTRACT
Objective To analyze the epidemiological characteristics of unintentional injuries among children patients at age of ≤ 14 years so as to provide scientific basis for prevention of the children injury. Methods ICD-10 coding was used to retrospectively analyze the epidemiological characteristics of the children patients with unintentional injuries at age of ≤ 14 years admitted from January to December 2009 and the factors affecting the prognosis were discussed. Results There were 3011 patients, with 1991 males (66.12%) and 1 020 females (33.88%). The patients at ages of < 1, 1-4, 5-9 and 10-14 years accounted for 8.24%, 53.30%, 27.90% and 10.56% respectively. The patients from the rural and urban areas accounted for 56.16% and 43.84% respectively. Trauma was the leading sort of injuries in four age groups, accounting for 70.56%, 62.68%, 89.64% and 87.74% respectively. Fall from height was the first cause of unintentional injuries in four age groups, with proportion for 47.58%,36.39%, 51.90% and 56.29% respectively. Muhinomial logistic regression analysis revealed that hospital stay, therapeutic mode ( operation/non-operation), inhabitancy ( urban/rural), causes of injuries and injury severity on admission were the risk factors affecting the prognosis (P < 0.05 ). The rural areas caused higher risk of disability than the urban areas ( OR = 2. 170 ,P < 0.01 ) and non-operation produced higher risk of death than operation (OR = 6.352,P < 0. 01 ). Conclusions The male patients with unintentional injury are more than the female ones, with the highest incidence rate in children at age of 1-4years. Trauma is the main kind of unintentional injury and the fall from height the leading cause of injury.The difference of the rural and urban areas indicates that correct choice of the preventive measures based oh the condition of the local area can attain effective prevention and control of the unintentional injuries.
ABSTRACT
OBJECTIVE:To analyze the chemical components extracted with supercritical CO2(SFE-CO2)from Eucalyptus tereticornis.METHODS: Volatile oil was extracted from E.tereticornis with SFE-CO2.The chemical component analyzed by GC-MS and its proportion was determined by normalization method.RESULTS: 28 compounds which account for 88.13% of the total peak area were separated and identified.The main components of volatile oil were eucalyptol (33.99%),borneol(8.88%),?-pinene (5.39%),caryophyllene (4.51%),(+)-4-carene (4.19%).CONCLUSION:This study can be served as a scientific basis for the further exploitation and utilization of E.tereticornis.
