较高碳含量钢种的低韧性和低的可焊性制约了它们在管线钢中应用,因此,建立起了低碳微合金化钢用于陆上和海上管线钢的良好需求。对于低碳微合金钢,在最小工艺和合金成本条件下获得所需的力学性能,合金设计起着重要作用。在合金设计过程中,虽然主要焦点是考虑从板坯再加热到最终轧制的热轧工艺,但是为保证钢的洁净度,也不能忽视炼钢和连铸过程,为此给出了合金设计和热轧参数的详细研究,以获得最佳的力学性能,包括在-25℃进行落锤撕裂试验获得较高的韧性。试验钢采用API 5L X70m PSL2的板坯,轧制成尺寸为25 mm×3 830 mm钢板。并将力学测试结果与显微组织分析和热轧参数相互关联。

＜正＞ Objective: To compare coronary artery disease pattern and effects of coronary artery bypass grafting （CABG） in diabetics having left ventricular （LV） systolic dysfunction （LVD） with those in non- diabetics. methods: The study included patients with LVD （ejection fraction （EF） less than 35% on echocardgiography） and undergoing CABG. Group - Ⅰ included diabetics and group - Ⅱ included non -diabetics. Records of coronary angiography were compared. Pre- and post CABG echocardiographic data were also compared. Results: Out of 267 patients included. 116 were in group - Ⅰ and 151 in group - Ⅱ. Relatively more patients in group - Ⅰ had significant stenosis in left anterior descending, obtuse marginal and right posterior descending artery than those in group - Ⅰ. Consistently, there was reduced LV contractility before CABG. in group -Ⅰ （EF: 27.5%） as compared to group- Ⅱ （29.5%）. However, improvement following 2 - months of CABG was greater in group - Ⅰ （EF: 35.3%） than group - Ⅱ （34.4 % ）. Reduction in LV diameters was also greater in group - Ⅰ. Conclusions: Indian diabetics having LVD and undergoing CABG are found with more stenosed coronary arteries. Diabetics gain greater improvement by CABG than non - diabetics.

大脑中动脉mRA血流信号异常与定量CT判断缺血改变的一致性:未来治疗学的研究目标

世界核心医学期刊文摘（神经病学分册） 2005年第2期1卷 35-35页

作者： Barber P.A. demchuk A.m. Hill m.D. 高中宝 Department of Clinical Neurosciences University of Calgary Institute for Biodiagnostics (West) 3330 Hospital Drive Calgary Alta. T2N 4N 1 Canada

Objectives: In this study we define the probability of vascular abnormality in the middle cerebral artery (mCA) territory according to the extent of ischaemic change seen using computed tomography (CT). We assessed the sensitivity and spe cificity of the hyperdense middle cerebral artery (HmCA) and the “dot”sign usi ng magnetic resonance angiography (mRA). methods: Patients presenting with ischa emic stroke had a CT scan ( mRI (m (ASPECTS) was applied to CT and diffusion weighted images (DWI) at basel ine and follow up (24 h) by five independent observers. The presence of HmCA and the mCA "dot" sign was also evaluated. An expert reader assessed the 3D time of flight (TOF) mRA in the anterior circulation for areas of decreased vascular si gnal in the mCA territory, with an absent signal taken to represent severely red uced or absent flow. Results: A total of 100 consecutive patients had baseline C T and mR scans. The median NIHSS was 9. The median CT ASPECTS was 8 and equalled the median DWI ASPECTS. There were a total of 10 HmCA and 19 mCA “dot”signs, with four patients having both HmCA and “dot”signs. A total of 47 mRA flow sig nal abnormalities were observed in the anterior circulation. Conclusions: In the absence of accessible neurovascular imaging, the extent of CT ischaemia (ASPECT S) is a strong predictor of vascular occlusion. The CT hyperdense artery signs h ave a high positive predictive value but low negative predictive value.

multiple z-Score Based method for Noninvasive Prenatal Test Using Cell-Free DNA in maternal Plasma

Open Journal of Genetics 2017年第1期7卷 1-8页

Objective: To improve the detecting accuracy of chromosomal aneuploidy of fetus by non-invasive prenatal testing (NIPT) using next generation sequencing data of pregnant women’s cell-free DNA. methods: We proposed the multi-Z method which uses 21 z-scores for each autosomal chromosome to detect aneuploidy of the chromosome, while the conventional NIPT method uses only one z-score. To do this, mapped read numbers of a certain chromosome were normalized by those of the other 21 chromosomes. Average and standard deviation (SD), which are used for calculating z-score of each sample, were obtained with normalized values between all autosomal chromosomes of control samples. In this way, multiple z-scores can be calculated for 21 autosomal chromosomes except oneself. Results: multi-Z method showed 100% sensitivity and specificity for 187 samples sequenced to 3 m reads while the conventional NIPT method showed 95.1% specificity. Similarly, for 216 samples sequenced to 1 m reads, multi-Z method showed 100% sensitivity and 95.6% specificity and the conventional NIPT method showed a result of 75.1% specificity. Conclusion: multi-Z method showed higher accuracy and robust results than the conventional method even at low coverage reads.

2015年发表在NEJm上的5项大动脉闭塞急性缺血性卒中血管内治疗的随机试验证实第二代血管内再通治疗装置（主要是支架取栓装置）优于单独内科治疗。但是目前尚不清楚症状超过6 h患者血管内治疗的风险和获益,同样也不清楚发病6 h内获益的程度和时间之间的关系。美国、欧洲和加拿大国家指南推荐血管内治疗的时间窗为6 h,但是美国食品和药品管理局推荐时间窗为8 h,加拿大指南补充认为时间窗可达12 h。
