结果 六家医院NICU符合筛查标准并完成ROP筛查的患儿639例中，发现ROP患儿69例，占10.8％。69例ROP患儿中，达到阈值或阈值前病变1型需要进行眼底激光光凝治疗者23例39只眼，占3.6％。

Methods: 45 case s of ASA Ⅰ-Ⅱ primiparae nearing labor were vandomly divided three groups rand omly (0.16%Rop group, 0.2%Rop group were assigned 15 cases).

随机选择 ASAⅠ～Ⅱ级临产初产妇45例，平均分为三组：0.16%Rop组和0.2%Rop组作为观察组，以及对照组15例。

Methods Potential related risk factors of ROP, such as age, sex, birth weight, FiO 2, duration of inspiring ox ygen, hyaline membrane dzsease, Apgar score, intracranial hemorrhage , recurrent apnea, broncho pulmonary dysplasia, patent ductus arteriosus were studied prospectively by univariate analysis and Logistic regression a nalysis in 135 preterm infants.

方法以 13 5例早产儿患儿为研究对象，对胎龄、性别、出生体重、吸氧时间、吸氧浓度、肺透明膜病、Apgar评分、颅内出血、支气管肺发育不良、反复呼吸暂停、动脉导管开放、眼底等进行检查。同时用单因素χ2 检验和多因素logistic回归分析筛选和判定早产儿ROP发生的危险因素。

A digital AGC circuit using a digital potentiometer to rep lace the feedback resistance of the amp lifierwas designed. In order to get an app rop riate gain, MCU adjusted the resistance of the digital potentiometer automatically according to the voltage value of amp lifierps output.

为使输入信号不受这一限制，设计了一种数字式自动增益放大电路，该电路采用数字电位器取代放大器的反馈电阻，单片机根据放大器输出电压自动调整数字电位器的阻值来调节放大器增益，使输出电压始终维持在所设定的上下限电压之间。

Another plug for newspapers: NFM increased its linage in the local paper by over 20% in 1989 off a record 1988 - and remains the paper's largest ROP advertiser by far.

另外提供一则新闻插播，NFM 在 1989 年增加 20%的报纸广告量，依旧是当地报纸的最大广告客户，(ROP 是指印在报纸上的广告，与事先印好的夹报有别)，就我所知，奥玛哈是唯一一个以家具业者为最大报纸广告客户的地区，许多客户在 1989 年都大砍广告量，但是就我们在喜斯糖果与 NFM 的经验来说，这实在是个天大的错误。
