由于望远镜主镜位置的调整与主镜位置的实时监测相关,本文设计了基于位移传感器的主镜位置监测系统。重点考虑镜室重力变形的影响,利用解析几何方法得到了解算主镜位置的算法。以实验室的1.2mSiC主镜作为试验镜进行了主镜位置实时监测试验。在主镜绕支撑架做俯仰转动时,通过布置在主镜背部和侧向的6个位移传感器,实时采集测量数据,并利用有限元方法计算镜室的变形;最后将镜室变形作为系统差和传感器测量值代入解算算法,得到主镜沿X、Y、Z三向平移、绕X、Y轴转动角度及主镜半径随温度变化值。测试结果显示:该试验主镜的支撑系统中的轴向支撑刚度远大于侧向支撑刚度。当镜室转动45°时,主镜的Z向平移变化只有20μm,而X向平移和Y向平移分别为146μm和100μm。试验结果验证了提出的实时监测方法和监测系统的准确性,为大口径主镜实时位置校正提供了依据。

目的:探讨汉防己甲素(tetrandrine,Tet)联合5-FU聚乳酸微球对兔增生性玻璃体视网膜病变(proliferati vevitreoretinopathy,PVR)IL-1β和TNF-α表达的影响。方法:随机分为A,B,C3组,建立兔眼外伤性PVR模型,向玻璃体中后部注入药物,A组注入含有Tet联合5-氟尿嘧啶(5-FU)聚乳酸微球的BSS悬浮液0.2mL,B组注入含有5-FU聚乳酸微球的BSS悬浮液0.2mL,C组注入25mg无药物聚乳酸微球的BSS悬浮液0.2mL,术后每天观察眼底变化,必要时行B超检查直到注药后第28d。分别于术后7,14,28d等3个时间点抽取各术眼玻璃体液0.2mL,酶联免疫吸附法(ELISA)检测玻璃体液中TNF-α,IL-2的含量。结果:Tet联合5-FU聚乳酸微球组与5-FU聚乳酸微球组及空白微球组相比,其玻璃体液中TNF-α,IL-2等炎性因子的含量也显著低于其他两组,方差分析P<0.01,差异有统计学意义。结论:Tet在眼内能够降低炎性因子TNF-α和IL-1β的表达,说明Tet可能通过在PVR炎症期发挥抗炎作用,抑制眼内炎症因子的释放,减弱炎症因子对炎性细胞的激活和趋化,从而起到降低PVR发生率的协同作用。

目的:观察电针对局灶性脑缺血大鼠丘脑腹后外侧核(VPL)神经生长因子(NGF)和生长休止特定蛋白7(Gas 7)表达的影响,探讨电针治疗局灶性脑缺血继发性损伤的可能机制。方法:采用随机数字表法将48只SD大鼠分为正常组、假手术组、模型组和缺血后电针治疗组(简称电针组),每组12只。采用线栓法复制右侧大脑中动脉栓塞模型。电针组电针"百会"和左侧"足三里"穴,每天1次,每次30 min,连续21d。免疫组织化学法和Western blot法检测大鼠右侧VPL中NGF和Gas 7的表达;尼氏染色法观察VPL神经元形态。结果:尼氏染色结果显示,正常组及假手术组右侧VPL结构清晰完整,胞核居中,核仁清楚;模型组VPL神经元染色较深,细胞核固缩;电针组神经细胞形态与正常组接近。免疫组织化学和Western blot检测结果一致,假手术组右侧VPL中NGF和Gas 7蛋白的表达与正常组比较差异无统计学意义(P>0.05);与正常组比较,模型组缺血侧VPL中NGF和Gas 7蛋白表达明显升高(P<0.05);与模型组比较,电针组缺血侧VPL中NGF和Gas 7蛋白表达显著升高(P<0.05)。结论:局灶性脑缺血大鼠缺血侧VPL中NGF和Gas 7的表达增强,可能参与了机体代偿性恢复的某些过程;电针可上调缺血侧VPL中NGF和Gas 7的表达,可能是电针改善脑缺血继发性丘脑损害的机制之一。

Background Acute Kidney injury(AKI) is a common complication in the early period post-liver transplantation(LT),posing an enormous obstacle to treatment efficiency and patient survival. However,the exact influencing factors of AKI are still unclear and a predicting model for AKI is desperately required in the *** Data of 102 consecutive liver transplants were reviewed in China,where most of patients underwent LT for hepatitis B-related liver diseases.A model for predicting AKI was established and further validated in a prospective *** was defined as an increased level of serum creatinine(>1.5mg/dL) or/and need for renal replacement therapy during the first week *** The incidence of AKI was 34.3%.Compared with non-AKI patients,AKI patients showed a significant lower survival rate. Multivariate analysis demonstrated the independent influencing factors of AKI were preoperative serum creatinine level>1.2 mg/dL,intraoperative urine output≤60 ml/h,intraoperative hypotension status,and intraoperative use of noradrenaline.A model was then established and showed a sensitivity of 86.7%,a specificity of 100% and an accuracy of 95.5%in predicting *** High preoperative serum creatinine level, low intraoperative urine output,and intraoperative hypotension contributed to the development of AKI and intraoperative use of noradrenaline presented as a protective *** predictive model could potentially facilitate early prediction and surveillance of AKI following LT especially in the patients with hepatitis-B related liver diseases.

To sensitize polyaniline with dyes by electrochemical polymerization, HClO 4 is employed as the dopant and oxidant, and the polyaniline with different sensitive properties is synthesized. The effect of sensitized emeraldine salt on the absorption spectrum is discussed in details. The maximum conductivity of sensitized films reaches 1.22 S/cm, and investigation on dye sensitizing of the polymer reveals that C.I. Direct Blue 71, C.I. Direct Blue 84, C.I. Direct Black 19 and CuPc-(COOH) 4 may enhance the photoconductivity of polyaniline greatly.
