Enantioseparation of aminoglutethimide was performed by high-speed counter-current chromatography with a two-phase system composed of ethyl acetate： methanol： water = 10： 1： 9. The lower phase contained 20 mmol/L of carboxymethly-β-cyclodextrin as chiral selector. The enantiomers were separated in 1.2 h and identified by chiral HPLC. This method was very efficient for the chiral preparative separation.

Bronchobiliary fistula(BBF) is a pathologic channel between the biliary tract and bronchial tree. In general, congenital BBF is relatively rare in adult patients. There are a few case reports suggesting that BBF is mainly secondary to hepatobiliary diseases, such as biliary obstruction, tumor, surgery, or liver abscess, and liver tumor is the predominant causative factor [1]. In addition, with the increasing number of liver and biliary surgeries and interventional therapies in recent years, more cases of BBF were reported as a postoperative complication [ 2, 3 ]. In this case, we presented a patient who underwent interventional treatment for liver tumor and was treated for his respiratory symptoms but diagnosed with BBF finally. Here, we summarized the clinical features and main diagnostic procedures of the case, aiming to provide evidence for early identification and diagnosis of BBF.

The mechanical property of shipbuilding steel BC has been studied by means of tensile test at various temperatures from 700 ℃ to 1000℃ with theGleeble-1500D thermo-mechanical *** results indicate that the yield strength and tensile strength of steel have an analogous change pattern as temperature decreasing,and the transition in variation rate of strength occurs at 800℃ in both of them;the hot ductility trough of steel BC is a temperature range from 725℃ to 800℃,while the best hot ductility ranges from 875℃ to 1000℃ with the ductility value over 80%.For the sake of understanding the fracture mechanism of the steel,fracture surface and microstructure of the specimens have been examined by scanning electron microscope and metalloscope *** results show that both the second phase particles and the pro-eutectoid ferrite surrounding the austenite boundaries play a significant role to the variation of hot ductility of steel ***,the research is important to the improvement and the further studies on the quality of steel during slab continuous casting process.

生物气溶胶在大气中扩散极易传播和发生各种流行疾病,也是生物武器投放的主要形式,实现生物气溶胶实时、远距离的探测显得尤为重要。构建了一台双波长荧光雷达用于大气中生物气溶胶的预警和识别。该雷达系统采用Nd∶YAG固体激光器作为激励光源,基频1 064nm、四倍频266nm作为工作波长。基于激光诱导荧光雷达探测原理,对红外波段的弹性散射信号和紫外波段诱导的荧光信号进行数值分析。结果显示,在探测误差小于10%的情况下,距离为1.0km时,单激光脉冲测量得到白天和夜晚细菌孢子的最小探测浓度分别为15 100个颗粒·L^(-1)和8 386个颗粒·L^(-1);当脉冲数累加到10 000时,白天和夜晚的细菌孢子最小探测浓度显著改善,分别为144个颗粒·L^(-1)和77个颗粒·L^(-1)。分析结果还表明,通过红外波段确定细菌孢子云团位置后,为了提高系统对细菌孢子的探测性能,可增加紫外激光脉冲数量,延长荧光信号采集时间。

目的:探讨使用透明带结合后的精子行ICSI,是否可改善ICSI治疗结局。方法:选择上一周期IVF完全不受精者或男方为少、弱、畸形精子症而接受ICSI治疗的不育患者,共收录106对不孕夫妇,将其随机分成常规ICSI对照组和利用未成熟卵透明带上结合的精子进行ICSI的试验组,每组53例,分析比较ICSI结局。结果:试验组的卵裂率、优质胚胎率、可使用胚胎率均显著高于对照组,差异有统计学意义(P0.05),但试验组种植率(29%)、多胎率(35.71%,10/26)明显高于对照组(17%、10.53%,2/19)(P<0.01)。结论:通过利用患者自体ZP结合的精子进行ICSI注射,能获取高质量胚胎和高种植率,这种改良的ZP结合ICSI方法或许能为今后ICSI治疗提供一个新的思路。
