3Evaluation of cardiovascular risk in patients with Parkinson disease under levodopa treatment显示文摘BackgroundLevodopa 是在有 Parkinson 疾病(PD ) 的病人的中间的治疗的不可缺少的选择。因为 L-dopa 治疗被显示增加浆液 homocysteine 层次,为心血管的混乱的一个著名风险因素,有在 L-dopa 治疗下面的 PD 的病人将在为未来的增加的风险心血管的事件。这研究的目的是在 levodopa treatment.MethodsThe 学习下面与 PD 在病人评估心血管的风险人口在 L-dopa 治疗下面与自发的 PD 由 65 个病人组成了。控制组包括了 32 年龄,性匹配没有认知衰落的个人。Echocardiographic 大小,浆液 homocysteine 层次和主动脉的有弹性的参数与 PD 和 controls.ResultsAs 在病人之间被作比较 L-dopa 治疗的一个期望的特征, Parkinson 组有显著地更高的 homocystein 层次(15.1 ±3.9 µ mol/L 对 11.5 ±3.2 µ mol/L, P = 0.02 ) 。当时,大动脉的膨胀性在有 PD 的病人是显著地更低的与控制相比(4.8 ±1.5 dyn/cm 2 对 6.2 ±1.9 dyn/cm 2, P = 0.016 ) 。另外,有 PD 的病人有更高大动脉的紧张和大动脉的僵硬索引(13.4%±6.4% 对 7.4%±3.6% , P <0.001 和 7.3 ±1.5 对 4.9 ±1.9, P <0.001 分别地) 。而且,浆液 homocysteine 层次被发现断然与大动脉的僵硬索引被相关,在浆液 homocysteine 的大动脉的膨胀性和层次之间有否定关联(r = 0.674, P <0.001;r =− 0.602, P <0.001,分别地) 有在 L-dopa 治疗下面的 PD 的 .ConclusionsThe 病人增加了大动脉的僵硬并且与健康个人相比损害了心脏舒张的功能。提高的浆液 homocysteine 层次可以是可能的 pathophysiological 机制。Zeki Yuksel Gunaydln Fahriye Feriha Ozer Ahmet Karagoz Osman Bektas Mehmet Baran Karatas Ash Vural Adil Bayramoglu Abdullah Celik Mehmet Yaman 2016Journal of Geriatric Cardiology2016,13,1:3
4Epidemiological and clinical features of paediatric open globe injuries in southwestern Turkey显示文摘AIM:To evaluate the epidemiologic,anatomic,and clinical features of open globe injuries in children.METHODS:The medical files of patients under the age of 16 who had been operated for an open globe injury at Akdeniz University Hospital's Department of Ophthalmology were retrospectively evaluated.RESULTS:A total of 90 patients were evaluated in this study.Among these patients,26(28.9%)were female and64(71.1%)were male.The mean age of the patients was7.7±4.2 years.The male/female ratio was observed to increase with increasing age(P=0.006,P=7.48).Injuries were most likely to occur in spring and autumn(P=0.028).The time interval between the injury and the surgical repair was 9.36±27.4h.Forty(44.4%)of the injuries occurred in the home,27(30%)occurred in the yard,and 21(23.3%)happened while playing in the street.The most common causes of injury were sharp metal objects(P<0.001).Injury to the cornea occurred in47(52.2%)of the patients(P<0.001).The most common complication to occur was cataract formation.Additional operations were necessary for 37(41.1%)of the patients.The final visual acuity was correlated with both the initial visual acuity of the wounded eye prior to surgery and the length of the wound(P<0.001,r=0.502 and P<0.001,r=-0.442,respectively).CONCLUSION:Open globe injuries that are suffered in childhood generally occur either at home,in the yard,or on the street,with sharp metal objects being the most common cause of injury.The initial visual acuity and the length of the wound are the most important determinants of the final visual acuity.Hatice Deniz Ilhan Ahmet Burak Bilgin Ash Cetinkaya Mustafa Unal Iclal Yucel 2013International Journal of Ophthalmology(English edition)2013,6,6:3

7Draper实验室微机械惯性敏感器的研制情况及近期测试结果显示文摘可氏振动陀螺仪(CVG)的工作原理是通过作用在振动质量上的哥氏效应来检测惯性转动的。Draper实验室的微机电系统(MEMS)中的CVG设计是利用支撑在与硅结构阳极粘接的玻璃基片的两个硅检测质量,进行电容耦合梳状驱动异相180°振动原理进行工作的,沿与速度矢量垂直的角运动使检测质量做离面运动,经电容检测到和放大得出惯性角速率的测量结果。经过对设计的不断改进,现在Draper CVG的偏置稳定性在温控(±0.25℃)状态下,6小时漂移测试已好于10°/h,在-40℃至+85℃范围内的温度补偿为50°/h,相应的偏置和刻度因数为200ppm,角度随机漂移的典型值为0.25°/√h,日观测的最好值为0.05°/√h。与之对应的MEMS力矩平衡加还度计也已研制,它是支撑旋转在玻璃片上的一非平衡硅跷板状检测质量,玻璃基片上提供传感器和静电力矩电容器,在温控状态下6小时漂移测试中已验证亚毫g性能,在-40℃至+85℃范围内的温度补偿性能为1mg,相应的偏置和度因数为200ppm,速度漂移为5cm/s/√h。本文也讨论了MEMG硅振荡加速度计(SOA),它通过依附在普通检测质量上电容耦合梳状硅谐振片的频率变化测量加速度。Ash,ME 2001惯导与仪表2001,,2:2
