A 22-year-old girl was admitted to our cardiology institute with Permanent tachycardia in last 6 years for diagnostic assessment and therapy. Doppler echocardiography show structural of heart is normal, ECG revealed a varied resting rate from 120 to 140 bpm, 1:1 AV ratio and long RP interval. P wave morphology was negative on leads I, II, III, aVF, and V4 to V6, positive on lead V1, and diphasic 1 /2 on lead aVL. Electrophysiology (EP) study was performed, Although the exactly mapping was performed in left inferior pulmonary vein and mitral annulus, however, no target point was found ahead of CS1-2, the tried discharge was invalid. The ablation catheter was entered the coronary sinus to guide electrical isolation, curing the tachycardia. The ECG returned to normal sinus rhythm. Through three years follow up, no AT recurrence.

Case Reports in Clinical Medicine 2015年第4期4卷 141-144页

作者： Jun Luo zhihong zhao Chan Jin Xinming Li Department of Cardiology ZhouPu Hospital Shanghai China

The prognosis of patients in whom the right coronary artery (RCA) arises from the left coronary sinus (LCS) is unequal. An initial intramural course of the coronary artery within the aortic media is considered to cause myocardial ischemia in cases of coronary anomalies. In this case report, we present one patient admitted due to chest pain on exertion that suggested angina. Her only risk factor for coronary artery disease was hypertension. Clinical examination findings that the origin of the right coronary artery from the LCS, through the aortic pulmonary sulcus with atherosclerotic narrowing and squeezed of the RCA critical ostial, stenosis at the ostium of the RCA and the middle of left anterior descending (LAD) coronary, intravascular ultrasonography (IVUS) showed LAD and RCA minimal lumen area were 3.9 mm2, 5.9 mm2;plaque burden 66%, 65% respectively. We inserted EXCEL 3.0 × 18 mm stent in LAD stenosis. No complaints and adverse events were noticed during a 1-year follow-up.

This paper compares numerical modeling of the effect of stress on solute transport （advection and matrix diffusion） in fractured rocks in which fracture apertures are correlated with fracture lengths. It is mainly motivated by the performance and safety assessments of underground radioactive waste repositories. Five research teams used different approaches to model stress/deformation, flow and transport pro- cesses, based on either discrete fracture network or equivalent continuum models. The simulation results derived by various teams generally demonstrated that rock stresses could significantly influence solute transport processes through stress-induced changes in fracture apertures and associated changes in per- meability. Reasonably good agreement was achieved regarding advection and matrix diffusion given the same fracture network, while some observed discrepancies could be explained by different mechanical or transport modeling approaches.

五四以来,中国传统写意的文人画遭到了引进的西方传统的写生观念与方法的挑战与猛烈抨击。而这种“科学”的写生观与方法在中国特定的社会与文化语境中,又不断注入新的内涵,使之具有了本土化的特色,逐渐成为中国现代美术最重要的创获之一。本文在回溯中国传统写生观念意涵的基础上,着重分析20世纪以来写生观念与方法的演绎,探讨写生的“误读”与“错位”现象,力求在新的时代语境中对写生的意义与价值有新的认识。

针对滚动轴承的故障诊断,设计并实现了一种基于双向长短期记忆网络(BiLSTM)的诊断模型。将原始振动信号直接作为模型输入,自动提取滚动轴承故障特征,可以对内圈、滚动体、外圈不同故障类型及不同损伤程度的滚动轴承进行故障识别。该模型通过BiLSTM神经网络自动提取轴承振动信号的深层信息,弥补了传统故障诊断方法需要人工提取特征的不足,实现端到端的滚动轴承故障智能诊断。滚动轴承实测振动信号实验结果表明故障识别准确率可以达到99.8%以上,该方法具有一定的应用价值。
