Clinical value of stereoscopic three-dimensional echocardiography in assessment of atrial septal defects: Feasibility and efficiency

Stereoscopic three-dimensional echocardiography（S-3DE） is a novel displaying technol-ogy based on real-time 3-dimensional echocardiography （RT-3DE）. Our study was to evaluate the feasibility and efficiency of S-3DE in the diagnosis of atrial septal defect （ASD） and its use in the guidance for transcatheter ASD occlusion. Twelve patients with secundum ASD underwent RT-3DE examination and 9 of the 12 were subjected to transcatheter closure of ASD. Stereoscopic vision was generated with a high-performance volume renderer with red-green stereoscopic glasses. S-3DE was compared with standard RT-3D display for the assessment of the shape, size, and the surrounding tis-sues of ASD and for the guidance of ASD occlusion. The appearance rate of coronary sinus and the mean formation time of the IVC, SVC were compared. Our results showed that S-3DE could measure the diameter of ASD accurately and there was no significant difference in the measurements between S-3DE and standard 3D display （2.89±0.73 cm vs 2.85±0.72 cm, P〉0.05; r=0.96, P〈0.05）. The appearance of coronary sinus for S-3DE was higher as compared with the standard 3D display （93.3% vs 100%）. The mean time of the IVC, SVC for S-3DE monitor was slightly shorter than that of the standard 3D display （11.0±3.8 s vs 10.3±3.6 s, P〉0.05）. The mean completion time of interven-tional procedure was shortened with S-3DE display as compared with standard 3D display （17.3±3.1 min vs 23.0±3.9 min, P〈0.05）. Stereoscopic three-dimensional echocardiography could improve the visualization of three-dimensional echocardiography, facilitate the identification of the adjacent structures, decrease the time required for interventional manipulation. It may be a feasible, safe, and efficient tool for guiding transcatheter septal occlusion or the surgical interventions.

海口市装修居室内空气中甲醛浓度调查

目的了解海口市装修居室内空气中甲醛的污染水平。方法在2015年5月对100户装修居室内空气中的甲醛浓度进行现场检测,对装修后不同时间、不同房间类型的检测结果进行统计学分析。结果装修居室内空气中甲醛总体浓度范围为0.016~0.263 mg/m~3,平均浓度为0.076 mg/m~3,总超标率为39.0%。装修1年内室内甲醛超标率为52.2%,平均浓度为0.095 mg/m~3,明显高于装修时间为1~3年和≥3年的室内甲醛浓度,差异均具有统计学意义,P0.05)。客厅的超标率最高为42.0%,厨房的超标率最低为36.0%,卧室的超标率为38.0%,随着装修时间的延长,客厅、厨房和卧室空气中的甲醛超标率呈逐渐下降的趋势。结论新装修居室内甲醛污染较严重,应加强通风及采取有效措施降低甲醛浓度,以减少甲醛污染的危害。     

入境人员集中隔离点房间新型冠状病毒污染状况分析

目的 了解入境人员集中隔离点房间新型冠状病毒污染状况,为集中隔离点规范管理提供科学依据。 方法 采集2021年12月18日—2022年1月16日入境人员集中隔离居住过的房间环境表面涂抹样本,用Real-Time PCR方法对新型冠状病毒核酸进行检测,并对房间污染状况进行分析。 结果 共采集房间环境标本21 150份,其中确诊病例房间35个,样本数为350份,检出新冠病毒核酸阳性25份,均在确诊病例房间内,检出率为7.14%(25/350),物品为马桶、门板、灯开关、地面、床头柜、洗漱台、桌面、遥控器等。81.81%(9/11)的奥密克戎变异株确诊病例房间内检出新冠病毒核酸阳性。 结论 新型冠状病毒肺炎(简称新冠肺炎)确诊病例隔离房间物体表面存在污染风险,尤其是奥密克戎变异株患者房间环境污染风险更高,应按相关要求落实闭环管理,采取严格隔离措施,规范做好消毒工作,才能切实阻断新冠肺炎交叉感染和外溢感染风险。     

房间照度调查分析

当前青少年视力减退为数甚多,已引起有关部门重视,但多数仅注意遗传和近业工作因素,而对直接关系到用眼功能的照度注意较少.有的对集体场所如教室阅览室等给予注意,但对家庭宿舍注意较少.而青少年常有2～3小时在家庭房间作习,故房间的照度较为重要.现将我们对部队营房照度测试的结果统计分析如下:     

居室灯具与健康

灯具在居室美化中的作用不可忽视。怎样科学、合理地装置灯具？这不仅需要考虑到光源的协调统一,还要照顾灯具与房间格局的和谐。在厅堂（客厅、餐厅）,是全家人经常聚会的地方,需在天花板上装一照明度较大的吊灯,使其通照全厅。在卧室只需房间中央装一组照明度不大的吊灯,床头放一台可灵活调整的床头灯,以适应在床上阅读书报的需要。

决不在房间里吸烟

戒烟对于一些人来说是很难的,各种应酬,都少不了香烟登场,名贵香烟成了身份的“名片”,加之长期吸烟的积习往往使戒烟最后都归于失败。“节烟”就成了一种无奈的下策。我以前每天吸烟近两包,怎么也无法降下来,且有越吸越凶之势。为此,我不敢买整条的香烟,就怕一条烟到家,不到五天就烧光了。我故意两包两包的买,是为了控制自己的烟量。
