简介：热障碍涂层(TBC)通常由于他们散布机械性质和严重服务条件展出不明确的一生。考虑这些无常，一个可靠性评价方法基于失败概率分析被建议。首先，一个限制状态方程被建立界定在失败和安全区域之间的边界，然后失败概率由在失败区域的概率密度功能的集成是计算的根据一阶或秒顺序时刻。与界面的失败有关的参数在TBC的二种类型跟随Weibull分布，这被显示出。TBC的界面的失败被材料性质和温度落下的热失配显著地在服务影响。

简介：AbstractObjective:To identify risk factors of saphenous vein graft (SVG) failure and to investigate the utility of anatomical SYNTAX score (SS) and SYNTAX score II (SS-II) in predicting SVG failure.Methods:A total of 598 patients who underwent angiography for clinical reasons after coronary artery bypass grafting (CABG) were included. Baseline data and factors related to SVG failure were analyzed at the patient and graft levels. Patients were divided in tertiles by anatomical SS and in three groups by SS-II revascularization recommendation, and SVG patency was analyzed across these groups.Results:Patency rates were similar in all SS-stratified and SS-II recommendation groups within 1, 5, and 10 years after CABG. At the patient level, fasting blood glucose (FBG) level <7.0 mmol/L was less common in SVG failure (68.0% vs. 76.2%). At the graft level, patients with SVG failure tended to have angiography later (4.0 years vs. 3.0 years), poorer FBG control (FBG <7.0 mmol/L: 68.2% vs. 74.7%), and more grafts anastomosed to the right coronary system (59.2% vs. 47.4%). Longer time interval after CABG was related to SVG failure both at the patient and graft levels, and odds ratio (OR)/P values (OR/P) were 1.282/0.029 and 1.384/0.016, respectively. Using independent graft and grafting to the right artery system as risk factors at the graft level, OR/Ps were 3.094/0.000 and 2.524/0.000, respectively.Conclusions:Longer time interval after CABG, independent grafts, and grafting to the right artery system are associated with SVG failure. Anatomical SS or SS-II may not be reasonable tools for predicting SVG failure.

简介：AbstractIn January 2019, the fourth rabies case caused by organ transplantation was noticed in China, with the conditions of one per year for the recent four years. Different from the previous cases, there were no definite epidemiological histories of exposure or rabies-related symptoms from this patient. This case strongly supports the call for the legislation of establishing a national-level management that will incorporate the screening programs on donors prior to the practice of organ transplantation to reduce the risks on rabies caused by organ transplantation.
