Beautiful Friendship and Happiness Accompanied——Mianyang Qiang Song and Dance Troupe Visits ROK

Gangneung is a city of some 230,000 people in Gangwon-do, on the east coast of the Republic of Korea popular as a tourist site for viewing the sunrise. It also has its annual Danoje Festival, an event that, since 2005, has always had a strong presence of Chinese performers from Sichuan Province.In 2012, it was the turn of a 21-member delegation of the Qiang Song and Dance Troupe of the Mian-yang Art College of the Sichuan Conservatory of Music to accept an

新中国成立初期中南区和华东区保存富农经济政策执行差异解析

新中国成立初期,中共中央制定了土地改革中保存富农经济的政策。在实际执行保存富农经济的政策过程中,地方各大区之间却存在较大差异。中南区和华东区作为两个典型地区,因地方调查情况、领导人思想倾向和基层干部群众经历不同,在执行政策结果上出现较大差异。中南区对富农经济的打击相对严重,华东区的富农经济则保存较好,这对当时和以后的经济发展产生了不同影响。     

企业工会主席胜任力研究

和谐是劳资关系发展的目标(Williamson,2002),和谐劳资关系是雇主雇员关系的发展趋势(Rainnie,1984).对15个发达国家的实证研究发现,劳资关系和谐与生产力增长之间存在显著正相关关系(Buchele&Christiansen,1999).工会组织情况是企业劳动关系和谐度评价的重要指标之一(贺秋硕,...     

Determination of multiple drugs of abuse in human urine using dispersive liquid–liquid microextraction and capillary electrophoresis with PDA detection

A new method was developed for pre-concentration and determination of multiple drugs of abuse in human urine using dispersive liquid–liquid microextraction (DLLME) and capillary electrophoresis (CE) with photodiode array detection. The method was based on the formation of tiny droplets of an organic extractant in the prepared sample solution using water-immiscible organic solvent (chloroform) dissolved in water-miscible organic dispersive solvent (isopropyl alcohol). The organic phase, which extracted eight drugs of abuse from the prepared urine solution, was separated by centrifugation. The sedimented phase was transferred into a small volume CE auto-sampler vial with 10 µL of 1% HCl methanol solution and evaporated to dryness. The residue was reconstituted in lidocaine hydrochloride (internal standard) aqueous solution and introduced by electrokinetic injection into CE. Under the optimum conditions, acceptable linear relationship was observed in the range of 3.0–500 ng/mL with the correlation coefficient (r) of 0.9982–0.9994 for spiked urine samples. The limit of detection (LOD) (S/N = 3) was estimated to be 1.0 ng/mL. A recovery of 75.7%–90.6% was obtained for spiked samples. The mean relative error (MRE) was within ±7.0% and the relative standard deviation (RSD) was less than 6.9%. The proposed DLLME-CE procedure offers an alternative analytical approach for the sensitive detection of drugs of abuse in real urine samples.

Key points

• The dispersive liquid-liquid microextraction (DLLME) was involved for the determination of drugs in urine with capillary electrophoresis with photodiode array detection (CE-PDA).
• Good linearity, sensitivity, recovery and precision were achieved.
• The proposed method was eco-friendly with microliter scale solvent consumption.

小鼠哮喘死亡主支气管上皮LCR值及mmp-2的表达

目的观察基质金属蛋白酶2(mmp-2)在实验性小鼠支气管哮喘死亡模型主支气管上皮的表达规律。方法 6～8周雄性健康小鼠30只,随机取20只建立哮喘死亡模型(B组),10只为空白对照组(A组)。提取小鼠死后主支气管组织,经HE和免疫组化染色(SP法)后,用图像分析系统分别观测并测量小鼠支气管软骨厚度和黏膜固有层厚度比值(LCR),并用免疫蛋白印记法(Western blot)检测主支气管上皮mmp-2。实验所得数据用SPSS 11.0统计学软件进行分析。结果 B组主支气管LCR 1～3周内逐渐上升,mmp-2免疫组化阳性染色平均光密度值(MOD)逐渐升高、灰度值亦升高,与A组比较,两组数据差异均具有显著性意义(P<0.01)。结论 LCR可反映气道壁的增厚和间质纤维化,并结合mmp-2灰度值增高变化,可望成为诊断哮喘猝死的辅助指标之一。     

Sex assessment using measurements of the first lumbar vertebra

Sex determination is a vital part of the medico-legal system but can be difficult in cases where the integrity of the body has been compromised. The purpose of this study was to develop a technique for sex assessment from measurements of the first lumber vertebrate. Twenty-nine linear measurements and five ratios were collected from 113 Chinese adult males and 97 Chinese adult females using digital three-dimensional anthropometry methods. By using discriminant analysis, we found that 23 linear measurements and two ratios identified sexual dimorphism (P<0.01), with predictive accuracy ranging from 57.1% to 86.6%. Using a stepwise method of discriminant function analysis, we found three dimensions predicted sex with 88.6% accuracy: (a) upper end-plate width (EPWu), (b) left pedicle height (PHl), and (c) middle end-plate depth (EPDm). This study shows that a single first lumber vertebra can be used for this purpose, and that the discriminant equation will help forensic determination of sex in the Chinese population.
