目的分析重庆地区肺高血压(PH)患者的临床特点、经济和营养状况、治疗和预后情况。方法选取2015年8月1日至2018年1月31日该院心内科门诊及住院的PH患者进行横断面调查研究并随访,超声心动图初筛,确诊方式为右心导管。结果500例患者经超声心动图初筛,126例患者行右心导管后确诊PH。原发疾病最常见的是先天性心脏病[30例(23.81%)]。60例(47.62%)患者有经济困难,80例(63.49%)患者存在营养风险。60例(47.62%)PH患者接受了PH靶向治疗,1年生存率和2年生存率分别为87.90%和84.00%,年龄(OR:8.23,95%CI:2.35~29.49,P=0.001)、PH靶向治疗(OR:0.28,95%CI:0.10~0.77,P=0.013)是PH患者死亡的保护因素。结论重庆地区PH患者的原发疾病主要以先天性心脏病为主,较小的年龄和接受PH靶向治疗是其死亡的保护因素。

1+3铝热连轧机生产的带材表面出现振纹,影响产品质量。根据振纹的特征并结合轧机的振动机理,确定振纹是由轧机的垂振现象引起的。分析了影响垂振的设备、工艺润滑、控制系统等因素,发现当卷取速度为1.1 m/s~1.4 m/s时,力的相互耦合触发轧机自激振动。通过优化带材中间坯轧制速度、轧制温度、乳液喷射压力、喷射流量及喷射模式,控制带材卷取速度,避开1.1 m/s~1.4 m/s卷取速度区间,消除了带材表面振纹。
