Aims: To demonstrate the feasibility and clinical utility of developing dynamic risk assessment models for ST- segment elevation myocardial infarction(STEMI) patients. Methods and results: In 6066 STEMI patients enrolled in the Assessment of the Safety and Efficacy of a New Thrombolytic- 3(ASSENT- 3) trial with complete electrocardiographic data, we assessed the probability of 30- day mortality over the following forecasting periods beginning at day 0(baseline), 3 h, day 2, and day 5 using multiple- logistic regression. These models were validated and simplified in independent samples of 1622 similar fibrinolytic- treated p atients from the ASSENT- 3 PLUS trial and in 814 STEMI patients undergoing primary percutaneous coronary intervention in the COMplement inhibition in Myocardial infarction treated with Angioplasty(COMMA)trial. The discriminatory power of these predictive models, from baseline to day 5, was excellent(c- statistics 0.80 to 0.87); and their predictive ability was supported by strong gradients in mortality outcomes as the risk score increased. Dynamic modelling also provided information on the change in prognosis over time which may be used to advise more appropriate therapeutic decisions, e.g. the identification of high- risk patients for possible co- interventions. Conclusion: Dynamic modelling for STEMI patients enhances the risk assessment and stratification and should provide valuable ongoing guidance for their management.

Objectives: To examine the interaction between ST segment depression on the baseline ECG and subsequent in-hospital revascularisation on six month mortality among patients with non-ST elevation acute coronary syndromes. To examine whether ST segment depression influenced clinical decision making and whether there was international variation in the use of cardiac procedures across ST segment depression categories. Methods: 11 453 patients enrolled in GUSTO-IIB(global use of strategies to open occluded coronary arteries), PARAGON(platelet IIb/IIIa antagonism for the reduction of acute coronary syndrome events in a global organisation network)-A, and PARAGON-B were studied. Patients were categorised as having no ST segment depression, 1 mm ST segment depression in two contiguous leads, and ST segment depression ≥2 mm in two contiguous leads. International practice across four geographic regions was examined: USA, Canada, Europe, and Australia/NewZealand. Results: Revascularisation appeared to have no impact on survival among patients with no ST segment depression; however, revascularisation was associated with a significant survival benefit among patients with ST segment depression ≥1 mm. There was an inverse relation between the extent of ST segment depression and the use of angiography as well as angioplasty(p< 0.01). However, patients with ST segment depression≥2mm were more likely to undergo bypass surgery. The only significant trend of increasing use of revascularisation procedures with increasing ST segment depression was observed in the USA. Conclusions: International practice patterns in procedure use appear to be insensitive to the extent of ST segment depression. Major opportunities for more efficient delivery of care exist in all regions.

通过对细叶桉、杂种桉、园锥花桉、大叶桉、白桉和柳桉六种桉树蒸腾率的比较,在充足水分和应力条件下,研究了它们的水分亏缺率。其结果表明,在充足水分和应力条件两个条件下,细叶桉和杂种桉不仅蒸腾率较低,而且还有内在的组织特征,即使在应力条件下,也能保持较高水平的水合作用。可以判断,这两种树种比其它树种更能耐旱。

我们认为,全球网络空间安全可能出现的各种情况均会落到两个极端路径的边界之内,即互联网死亡与互联网天堂的中间状态。今天全球化的世界越来越依赖于互联网。这个创新性的网络空间具有帮助维护世界和平,促进繁荣和增进全球信息交流的潜力。但是,最近发生的事件却显示出相反的趋势,即网络攻击和网络空间危险性的增加。在北美、亚洲和欧洲揭发出的大规模网络空间监听事件引发人们的思考。因此,下一个十年,全球网络空间安全治理的演进显得极其重要。

目的应用心肌对比成像（MCE）评价硝酸甘油对心肌血流灌注的直接影响。方法实验应用12只具有静息状态血流限制的左前降支近端狭窄的开胸犬（其中6只结扎远处的冠脉以消除侧支循环的影响）,根据远处的冠脉是否结扎分组（非结扎犬为组1、结扎犬为组2）。分别在静息和左冠脉主干内直接输注硝酸甘油（0.3-0.6μg·kg^-1）状态下,测定全血黏滞性（WBη）和心肌血管阻力（MVR）,同步应用放射性标记微球测定心肌血流量（MBF）,MCE评估心肌血流容积（A）和心肌血流速度（β）。结果与静息状态相比,经冠脉内输注硝酸甘油时,组1和组2实验犬正常区、整个缺血区和缺血中心区的MBF均明显增加（P〈0.05）,同时伴有MVR和WBη明显减低（P〈0.05）。MCE显示正常灌注区和整个缺血区β增加的程度明显大于标准化A增加的程度（P〈0.05）;标准化A和β增加（%）与A与β的乘积（A×β）增加（%）之间均有良好的相关性。然而,无论正常灌注区和整个缺血区标准化A增加（%）与A×β增加（%）之间相关方程的斜率明显小于β增加（%）与A×β增加（%）之间的斜率（P〈0.05）。结论硝酸甘油可降低血液黏滞性和心肌血流阻力,进而增加心肌的血液供应,后者主要是源于红细胞在心肌微循环中流动的速度增快所致。MCE是全面定量评价心肌血流灌注的良好方法。

Finite element (FE) analysis has become an increasingly popular technique in the study of human joint biomechanics, as it allows for detailed analysis of the joint/tissue behavior under complex, clinically relevant loading conditions. A wide variety of modeling techniques have been utilized to model knee joint ligaments. However, the effect of a selected constitutive model to simulate the ligaments on knee kinematics remains unclear. The purpose of the current study was to determine the effect of two most common techniques utilized to model knee ligaments on joint kinematics under functional loading conditions. We hypothesized that anatomic representations of the knee ligaments with anisotropic hyperelastic properties will result in more realistic kinematics. A previously developed, extensively validated anatomic FE model of the knee developed from a healthy, young female athlete was used. FE models with 3D anatomic and simplified uniaxial representations of main knee ligaments were used to simulate four functional loading conditions. Model predictions of tibiofemoral joint kinematics were compared to experimental measures. Results demonstrated the ability of the anatomic representation of the knee ligaments (3D geometry along with anisotropic hyperelastic material) in more physiologic prediction of the human knee motion with strong correlation (r ≥ 0.9 for all comparisons) and minimum deviation (0.9° ≤ RMSE ≤ 2.29°) from experimental findings. In contrast, non-physiologic uniaxial elastic representation of the ligaments resulted in lower correlations (r ≤ 0.6 for all comparisons) and substantially higher deviation (2.6°≤ RMSE ≤ 4.2°) from experimental results. Findings of the current study support our hypothesis and highlight the critical role of soft tissue modeling technique on the resultant FE predicted joint kinematics.

The influence of low energy laser peening on fatigue lives of Ti-6Al-4V was investigated. Laser peening was carried out on Ti-6Al-4V samples. Laser peened samples were characterized by residual stress analysis, surface roughness measurements, X-ray diffraction, optical microscopy, nanoindentation hardness tests, scanning and transmission electron microscopy and fatigue testing. Laser peening resulted in the formation of nanocrystallites on the surface and near surface regions with associated increase in hardness and introduction of compressive residual stress. Owing to positive influence of nanostructured surface and compressive residual stress, fatigue lives of the laser peened samples were significantly increased compared to the unpeened samples.
