目的探讨妊娠期高血压疾病采用硫酸镁联合拉贝洛尔治疗的效果。方法选择60例妊娠期高血压疾病患者为研究对象,采用随机数字表法分为对照组和研究组,每组30例。对照组给予硫酸镁治疗,研究组在对照组基础上采用拉贝洛尔治疗,比较两组舒张压(DBP)、收缩压(SBP)、平均动脉压(MAP)及不良妊娠结局。结果治疗前,两组DBP、SBP、MAP水平比较差异均无统计学意义(P>0.05);治疗后,两组DBP、SBP、MAP水平均优于治疗前,且研究组优于对照组(P<0.05);研究组不良妊娠结局发生率低于对照组(P<0.05)。结论妊娠期高血压疾病采用硫酸镁联合拉贝洛尔治疗效果较好,可改善患者血压水平,降低患者不良妊娠结局发生风险,保护母婴健康,值得临床推广与应用。

烘丝的最佳工艺参数难以确认,且叶丝含水率预测误差较大。为了在信息技术方面辅助提升烟草成品质量,研究基于极限学习机(ELM)的烘丝筒出口叶丝含水率预测模型。选取叶丝烘丝过程中松散回潮、预混柜、润叶加料等工艺阶段环境温度、湿度、加水比例等工艺参数。通过随机森林方法,将处理后有效数据中的各烘丝工艺参数以平均精准度逐渐减少顺序进行重新排序,筛选出对烘丝筒叶丝含水率预测作用较大的烘丝工艺参数。将筛选后的烘丝工艺参数作为ELM的输入数据,获取叶丝含水率预测结果。以含水率预测平均绝对误差最小为差分进化算法的适应度函数,优化ELM的隐含层神经元数量,提升烘丝筒出口叶丝含水率预测精度。试验结果表明,该模型可实现烘丝筒出口叶丝含水率预测,且预测误差小于0.3%,预测精度高。该研究有助于提升烟草质量。
