目的 了解杭州市富阳区0～14岁儿童意外伤害流行病学特征.方法 对2014-2018年富阳区3家伤害监测哨点医院首诊儿童意外伤害病例人口学特征、伤害发生的原因、地点、部位、程度等进行描述性分析.结果 5年共报告儿童意外伤害6 989例,男女比为1.61∶1.意外伤害原因前5位为动物伤(38.47％)、跌伤/坠落(36.26％)、刺割伤(7.21％)、钝器伤(5.04％)、异物嵌入(3.21％),不同性别和年龄别儿童意外伤害原因构成差异均有统计学意义(P值均＜0.05).意外伤害发生地点前3位为家中(77.69％)、学校(9.44％)、街道/公路(9.16％),随年龄增长在家中意外伤害发生比例逐渐下降,在学校发生比例逐渐上升.意外伤害发生部位前3位依次为上肢(37.54％)、下肢(26.43％)和头部(26.03％);轻度占82.82％.结论 应针对儿童意外伤害高发人群和多发地点,采取有效综合干预措施.

目的 分析2014—2018年杭州市富阳区成人伤害的时间分布,并预测2019年成人伤害趋势.方法 收集杭州市富阳区三家医疗机构2014—2018年成人伤害病例资料,建立时间序列求和自回归滑动平均模型(ARIMA)进行分析,并预测2019年富阳区成人伤害趋势.结果 2014—2018年杭州市富阳区3家医疗机构每月成人伤害接诊例数随时间变化较平稳,建立ARIMA(1,0,0)模型,Ljung-Box Q检验无统计学意义(P>0.05),预测2019年1—12月成人伤害接诊病例数以7月最多,1540例占9.76％.2019年1—4月模型预测值与实际观测值相对误差为0.13.结论 2019年1—12月杭州市富阳区成人伤害病例数呈上升趋势,且在7月达到最大值.

Objective To introduce a technique for preparing the slide specimens of adult Schistosoma ja-ponicum and its eggs obtained from the sentinel mice.Methods Slide specimens for the adult worms were prepared by fixation, staining, dehydration, transparency and mounting, whereas specimens for eggs were prepared by doub-le slides.Results By reference to related literatures and relevant laboratory practice guidance, standard procedures for preparing the specimens of adult Schistosoma japonicum and its eggs obtained from the sentinel mice were suc-cessful y established.Conclusion Specimens for the adult Schistosoma japonicum and its eggs obtained from sentinel mice can be prepared in standard manner, which may contributes to effective preservation of the worms for use in scientific research and class teaching in the context of gradually declined prevalence of schistosomiasis.
