背景尽管开放性和目标导向（goal—directed，GD）的液体治疗在围术期都应用大量液体，但两者对围术期预后的影响却明显不同。我们致力于判断是否某种管理策略优于其他策略。方法我们从mEDLINE、EmBASE、Pubmed（1951—2011．4）以及注册的Cochrane对照试验中选择在大手术中应用GD或限制性与开放性（restrictive versus liberal，LVR）液体治疗的随机对照试验（randomized controlled trials，RCTs），不设语言限制。GD和LVR两层进行间接比较。结果该研究纳入来自23项GDRCT[样本量中位数=90，四分位距（interquartile range，IQR）57～JD9]的3861例患者和来自12项LVRRCT（样本中位数=80，IOR36一J5J）的1160例患者。开放性和GD液体治疗均比其相应的对比策略应用更多液体，但两者对结果的影响却明显不同。开放性补液与限制性液体治疗患者比较，肺炎[风险比（riskratio，RR）2．2，95％可信区间[（confidenceinterval，CI）J．0～4．5J和肺水肿（RR3．8，95％CIJ．J—J3）风险更高，住院时间更长[平均差异（mean difference，mD）2天，95％C10．5。3．4]。与非GD液体治疗患者比较，GD治疗患者的肺炎风险（RR0．7，95％C10．6—0．9）和肾脏并发症（RR0．7，95％C10．5。0．9）减少，住院时间缩短（mD2天，95％CIJ一3）。与GD治疗患者比较，开放性液体治疗患者住院时间延长（4天。95％CI3．4～4．4）、肠蠕动恢复时间延长（2天，95％CIJ．j～2．3）、肺炎风险增加（足足月3，95％CIJ．8～4．8）。结论GD液体治疗比无血流动力学目标指导的开放性液体治疗的围术期预后更好。但GD液体治疗是否优于限制性液体治疗仍不确定。

Effect of Roasting and Germination on Proximate, micronutrient and Amino Acid Profile of Breadnut Seed (Artocarpus camansi) Flours

The proximate, micronutrient and amino acid profile of roasted and germinated breadnut seed flour were evaluated. Fresh mature fruits (1.5 kg) of breadnut were purchased from Relief market in Imo State, Nigeria. The breadnut seeds were divided into three portions for different unit operations, namely raw, roasted and germinated. Samples were analyzed for proximate, minerals and amino acids compositions. Statistical significance was set at p minated breadnut seeds;fibre (2.20%) and ash (7.20%) were significantly higher (p moisture (11.05%) were significantly higher (p micronutrient composition shows that iron (74.35 mg/100g) was higher in roasted breadnut seed, phosphorous (12.95 mg/100g) and zinc (30.4 mg/100g) were higher in germinated breadnut seed flour while calcium (0.04%), magnesium (0.05%), vitamin A (0.27%) and vitamin C (0.85%) were higher in raw breadnut. All the essential amino acids except norleucine were present in the breadnut in varying quantities. Between roasting and germination, essential acids;valine more in germinated breadnut seeds while leucine methionine were higher in roasted breadnut seed flour. The use of roasting and germination should be used in processing breadnut seeds. The use of breadnut seed flours as composite flour in food production may help to provide protein and micronutrient among the vulnerable groups.

Dietary Fibre and Fatty Acid Evaluation of Boiled, Roasted, Germinated and Fermented Breadnut (Ukwa bekee) Seed Flours

作者： joy Adaku. C. Amadi Sylvia Ogechi Ndukwu Chijioke Nnaemeka Nwachukwu Department of Nutrition and Dietetics Imo State University Owerri P.M.B. 2000 Nigeria Department of Food Science and Technology Imo State University Owerri P.M.B. 2000 Nigeria

Evaluation of dietary fiber and fatty acid composition of boiled, roasted, fermented and germinated breadnut seed flour was investigated. The seeds were dehulled and washed. It was divided into four equal parts for different processing techniques: boiled, roasted, germinated and fermented. They were analyzed for dietary fibre and fatty acid composition using standard methods. Data were subjected to statistical analysis using Statistical Product for Service Solution (SPSS) version 23.0. Values were expressed as means and standard deviation, Duncan multiple range test was used in separating the means at 95% confidence interval. Dietary fibre composition showed that breadnut seed flours range from 4.94%(fermented breadnut seed flour) to 5.42%(roasted breadnut seed flour). Fatty acid profile showed that breadnut seed flours contain a greater amount of non-essential fatty acids which were highly significant (p mented breadnut flour. Stearic acid was the only prominent non-essential fatty acid in the breadnut seed flour and ranged from 4.40%(fermented breadnut seed flour) to 6.27%(germinated breadnut seed flour). The study revealed that all the processed breadnut seed flours have appreciable quantities of dietary fibre and essential fatty acids than non-essential fatty acids. Breadnut seed should be recommended in wheat substitution in bakery industry and culinary uses. It is also recommended for weight loss program.

Laboratory testing of a shuttle car canopy air curtain for respirable coal mine dust control

引用

International Journal of Coal Science & Technology 2018年第3期5卷 305-314页

作者： W. R. Reed Y. Zheng m. Yekich G. Ross A. Salem Pittsburgh mining Research Division Centers for Disease Control and Prevention National Institute for Occupational Safety and Health 626 Cochrans Mill Rd. PittsburghPA 15236 USA J.H. Fletcher Inc. Huntington WV USA marshall University Huntington WV USA

Canopy air curtain （CAC） technology has been developed by the National Institute for Occupational Safety and Health （NIOSH） for use on continuous miners and subsequently roof bolting machines in underground coal mines to protect operators of these machines from overexposure to respirable coal mine dust. The next logical progression is to develop a CAC for shuttle cars to protect operators from the same overexposures. NIOSH awarded a contract to marshall University and J.H. Fletcher to develop the shuttle car CAC. NIOSH conducted laboratory testing to determine the dust control efficiency of the shuttle car CAC. Testing was conducted on two different cab configurations： a center drive similar to that on a joy 10SC32AA cab model and an end drive similar to that on a joy 10SC32AB cab model. Three different ventilation velocities were tested-0.61, 2.0, 4.3 rrds （120, 400, and 850 fpm）. The lowest, 0.61 m/s （120 fpm）, represented the ventilation velocity encountered during loading by the continuous miner, while the 4.3 m/s （850 fpm） velocity represented ventilation velocity airflow over the shuttle car while tramming against ventilation airflow. Test results showed an average of the dust control efficiencies ranging from 74 to 83% for 0.61 m/s （120 fpm）, 39%-43% for 2.0 m/s （400 fpm）, and 6%-16% for 4.3 m/s （850 fpm）. Incorporating an airflow spoiler to the shuttle car CAC design and placing the CAC so that it is located 22.86 cm （9 in.） forward of the operator improved the dust control efficiency to 51%-55% for 4.3 m/s （850 fpm） with minimal impact on dust control efficiencies for lower ventilation velocities. These laboratory tests demonstrate that the newly developed shuttle car CAC has the potential to successfully protect shuttle car operators from coal mine respirable dust overexposures.
