The results showed that the adults of Monochamus alternatus (JPS) were killed and the pine tree mortality rate was very low. There was no dead tree in sprayed Pinus massoniana forest in 4 years but 6% dead rate in the CK forest in Fuyang City. The mortality rate in the sprayed Pinus nigra forest in 2 years was below 1%, but 30% in the CK forest in an island of Zhoushan City. Large number of adults of JPS reared with Pinus nigra branches which sprayed fenitrothion (200×～600×) died in 24 hours, all died in 8 days, but only 13.3% died in the CK. Applying in large area, the control effect was obvious.展开更多
目的:分析早产儿视网膜病变的转归情况及其进展至重度的危险因素。方法:选取2016年1月-2019年6月本院95例视网膜病变早产儿为研究对象。随访6个月,观察所有患儿的转归情况,比较不同新生儿因素(性别、胎龄、体重、1 min Apgar评分、感染...目的:分析早产儿视网膜病变的转归情况及其进展至重度的危险因素。方法:选取2016年1月-2019年6月本院95例视网膜病变早产儿为研究对象。随访6个月,观察所有患儿的转归情况,比较不同新生儿因素(性别、胎龄、体重、1 min Apgar评分、感染情况及先天性疾病情况)及其他因素(机械通气时间、母亲妊娠期疾病情况、肺表面活性物质应用情况及分娩方式)者的转归情况,并分析早产儿视网膜病变进展至重度的危险因素。结果:95例早产儿中进展至重度者30例(31.58%),自然消退者65例(68.42%)。不同性别、先天性疾病、母亲妊娠期疾病、肺表面活性物质应用情况及分娩方式的早产儿转归情况比较,差异均无统计学意义(P>0.05),而不同胎龄、体重、1 min Apgar评分、感染情况及机械通气时间的早产儿转归情况比较,差异均有统计学意义(P<0.05);多因素logistic回归分析显示,胎龄、体重、1 min Apgar评分、感染情况及机械通气时间均为早产儿视网膜病变进展至重度的危险因素(P<0.05)。结论:早产儿视网膜病变进展至重度的概率较高。胎龄、体重、1 min Apgar评分、感染情况及机械通气时间均为早产儿视网膜病变进展至重度的危险因素,可作为防控与干预措施制定的参考依据。展开更多
