为了探究水分亏缺胁迫对马铃薯块茎产量构成的影响,以马铃薯品系BFL10和BFL12为试验材料,对不同水分胁迫状态下马铃薯各生育期的株高、分枝数、匍匐茎数量、单株结薯数量和单株结薯重量进行测定。结果表明:水分亏缺胁迫对马铃薯株高和分枝数的影响因品种熟性而异;重度水分亏缺胁迫显著降低了两个品系的单株结薯数量、单株大薯数量和单株结薯重量,轻度水分亏缺胁迫显著降低了单株大薯数量,推测轻度水分亏缺可能通过影响薯块膨大降低产量,而重度水分亏缺是通过影响薯块膨大和减少薯块数量两个方面降低产量。

目的探讨新发2型糖尿病(T2DM)合并非酒精性脂肪肝(non-alcoholic fatty liver disease,NAFLD)患者血清尿酸水平和血液流变学指标的关系。方法选取2010年4月至2012年3月于解放军第四一一医院确诊的437例新发T2DM患者,根据是否合并NAFLD分为2组,未合并NAFLD为A组,合并NAFLD为B组。检测所有患者身高、体质量、血压、血糖、血脂、血尿酸、血液流变学及肝脏B超等相关指标并进行比较,同时选取相应年龄和性别分布的健康体检者作为对照组。结果A组和B组患者体质指数(BMI)、总胆固醇(TC)、三酰甘油(TG)、低密度脂蛋白(LDL-C)、血清尿酸、糖化白蛋白(GSP)均高于对照组,其中BMI、TG、尿酸、GSP在A组与B组间比较差异有统计学意义(P <0. 05)。B组患者红细胞压积、红细胞变形指数、纤维蛋白原、血液黏度、血压还原黏度、血栓形成系数等血液流变学指标与A组比较差异有统计学意义(P <0. 05)。对照组、A组及B组3组间高尿酸血症的患病率分别为2. 7%、10. 5%、20. 7%,差异有统计学意义(P <0. 05)。控制了年龄、性别、BMI、TC、TG等水平后,血尿酸水平与红细胞压积、红细胞聚集指数、红细胞刚性指数、血液黏度、血液还原黏度、微循环滞留时间、血栓形成系数等血液流变学指标存在正相关。结论 T2DM合并NAFLD患者患高尿酸血症的比例更高,且血尿酸水平是影响血液流变学的一个重要因素,临床应对其给予重视。

The fiber optic sensing technology provides data support in structural health monitoring of the macro facilities, including design, construction, and maintenance of bridges, tunnels, ports and other infrastructures. In this paper, a distributed vibration sensing system is proved to be responsive to a single touch over a 1.8-m-long equivalent fiber segment, covering a vibration frequency from 5 Hz to 25 kHz. The sensing fiber was arranged as an S type layout on the bridge to recognize the standing state, windblown disturbance, and walking vibration. Moreover, the knocking and climbing events are recognized fiber laying spinning lines and hanging on the fences, respectively. The demonstration shows an accurate positioning and sensitive vibration monitoring applied on the automated three-dimensional(3D) printed bridge, which is applicable to all kinds of 3D printed facilities as intelligent sensory neuro-networks.
