智能母婴监护系统的设计与实现

母婴监护系统现已成为产科产前、产时行之有效的监护手段,能通过胎心率曲线诊断胎儿的健康状况,对提高出生人口素质,减少残疾婴儿的出生具有重要作用。传统的母婴监护系统体积较大、操作比较复杂、实时性差、价格比较昂贵。因而设计了一种智能母婴监护系统,根据嵌入到无线智能传感器中的算法提取出稳定的胎心率,将胎心率以及孕妇其它监护数据以无线的方式发送到本地或远程监护中心,本地监护设备或远程的监护中心将各项数据进行实时处理、分析、显示或报警,辅助医生或将信息及时反馈回来通知孕妇进行诊治。

320份市售熟肉制品的微生物检验结果分析

目的了解市售熟肉制品被微生物污染的状况,为食源性疾病的预防和控制提供科学依据。方法一年内分四季抽取320份熟肉制品,依照国家标准进行检验和评价分析。结果共检熟肉制品320份(城区160份,乡镇160份),合格130份,总合格率为40.6%;菌落总数合格193份,合格率60.3%;大肠菌群合格149份,合格率46.6%;检出致病菌和条件致病菌33份,检出率10.3%。结论中山市市售熟肉制品被微生物污染的程度较为严重,总合格率偏低,不合格主要是大肠菌群。检出致病菌和条件致病菌,提示要警惕熟肉制品引发食物中毒、食源性疾病。     

社区适老性规划设计研究

我国已成为世界上老龄人口数量最 多的国家,老年人生活和居住问题日益突出, 如何改善现有的居住环境,使老年人真正感 觉到老有所养、住有所居,是规划师亟待解 决的重要问题。本文从我国人口老龄化现状 入手,结合我国实际探讨了社区适老性的必要 性,对当前老年人的居住需求进行了分析,从 社区总体布局、老年住宅设计、社区空间环境 和社区公共服务设施4个方面提出了应对老 龄化的社区适老性规划设计的措施。     

探讨老年病员药物性静脉炎的预防及护理

目的观察多源频谱仪照射预防老年病员药物性静脉炎的疗效。方法选择78例长期住院、反复外周静脉输液的老年病员,输注药物为血管刺激性较强的药物(前列地尔、奎诺酮类抗生素),随机平均分为A、B2组,A组采用传统的局部硫酸镁湿敷;B组采用MF-多源频谱治疗仪局部照射。结果B组病员药物性静脉炎发生率低,局部皮肤反应轻微,疗效明显优于A组(P<0.05),差异有显著性。结论反复外周静脉输入血管刺激性较强的药物,采用MF-多源频谱治疗仪局部照射可以预防老年病员药物性静脉炎,保护外周静脉血管,减轻病员痛苦,增强病员的治疗依从性,提高生活质量。     

Nationwide monitoring of selected antibiotics: Distribution and sources of sulfonamides, trimethoprim, and macrolides in Japanese rivers

We report the results of a nationwide survey of commonly used human and veterinary antibiotics (7 sulfonamides, trimethoprim, and 4 macrolides) in 37 Japanese rivers. Concentrations of the sum of the 12 target antibiotics ranged from undetectable to 626 ng/L, with a median of 7.3 ng/L for the 37 rivers. Antibiotics concentrations were higher in urban rivers than in rural rivers and were correlated with those of molecular markers of sewage (crotamiton and carbamazepine). Macrolides were dominant over sulfonamides in urban rivers. Sulfonamides, especially sulfamethazine (used in animals), were dominant in a few rivers in whose catchment animal husbandry is active. However, these signals of veterinary antibiotics were overwhelmed by those of human antibiotics in lower reaches of most rivers. The analysis of the antibiotics in all 88 samples showed that the target antibiotics in Japanese rivers are derived mainly from urban sewage, even though larger amounts of antibiotics are used in livestock. Most of the livestock waste-derived antibiotics are unlikely to be readily discharged to surface waters.     

46例坐位开颅手术的围手术期护理体会

目的坐位手术是神经外科用于后颅窝,高颈段脊髓和部分松果本肿瘤切除的主要体位之一。方法优点为暴露好,术中出血少,术者操作方便。结果由于术式特点,术中易引起体位性和失血性低血压,手术野高于心脏水平,静脉压相对较低,空气易进入静脉内引起空气栓塞。结论术后易发生颅内血肿,故切实做好围手术期护理至关重要。     

Testing a series of causal propositions relating time in child care to children’s externalizing behavior.

[Correction Notice: An erratum for this article was reported in Vol 46(2) of Developmental Psychology (see record 2010-03975-013). On the first page of the article “Testing a Series of Causal Propositions Relating Time in Child Care to Children’s Externalizing Behavior,” by Kathleen McCartney, Margaret Burchinal, Alison Clarke- Stewart, Kristen L. Bub, Margaret T. Owen, Jay Belsky, and the NICHD Early Child Care Research Network (Developmental Psychology, 2010, Vol. 46, No. 1, pp. 1–17), author Alison Clarke- Stewart’s name was misspelled as Aliso Clarke-Stewart. In addition, the e-mail address listed for the corresponding author Kathleen McCartney is incorrect. The correct e-mail address is: kathleen_mccartney@gse.harvard.edu. The online versions of this article have been corrected.] Prior research has documented associations between hours in child care and children’s externalizing behavior. A series of longitudinal analyses were conducted to address 5 propositions, each testing the hypothesis that child care hours causes externalizing behavior. Data from the National Institute of Child Health and Human Development Early Child Care Research Network (NICHD) Study of Early Child Care and Youth Development were used in this investigation because they include repeated measures of child care experiences, externalizing behavior, and family characteristics. There were 3 main findings. First, the evidence linking child care hours with externalizing behavior was equivocal in that results varied across model specifications. Second, the association between child care hours and externalizing behavior was not due to a child effect. Third, child care quality and proportion of time spent with a large group of peers moderated the effects of child care hours on externalizing behavior. The number of hours spent in child care was more strongly related to externalizing behavior when children were in low-quality child care and when children spent a greater proportion of time with a large group of peers. The magnitude of associations between child care hours and externalizing behavior was modest. Implications are that parents and policymakers must take into account that externalizing behavior is predicted from a constellation of variables in multiple contexts.
