Objective：To investigate the efficacy and safety of the second generation argon plasma coagulation（VIO APC） in the ablation of Barrett＇ s Esophagus. Methods：A total of 35 patients with uncomplicated Barrett＇ s esophagus entered into a prospective, randomized, unblinded study comparing the treatment VIO APC combined with a proton pump inhibiter with a proton pump inhibiter administered alone. VIO APC was performed at a power setting of 40W, and argon gas flow at 1.5-2.0 L/min, and＂ forced＂ mode. Ablative treatment was repeated until either no Barrett＇ s epithelium remained or a maximum of 5 treatment sessions occurred. Results：In the ablation group, macroscopic complete ablation was achieved in 14 of 18 patients, and complete ablation confirmed by histology in 12 of 18 patients （P 〈 0.01）. Buried glands were observed in 2 patients who had achieved macroscopic ablation. The Barrett＇s mucosa averaged a reduction of 65%（range 50-75%） in the remaining 4 patients. In the control group, only 2 patients had partial regression, median 30%（range 20-40%）. In the ablation group, post-treatment 4 patients had transient retrosternal pain, and 3 patients had mild epigastric discomfort. One patient had a small hemorrhage during the procedure, which ceased after norepinephrine and thrombosin were administered through the endoscope biopsy channel. No adverse events were observed in the control group. During 11.8（4-15） months follow-up, patients who had achieved the complete ablation have no evidence of relapse of Barrett＇ s esophagus. Conclusion：VIO APC with a relatively low power setting can effectively ablate the Barrett＇ s mucosa. No severe adverse events were observed. Long-term follow-up is needed to assess cancer prevention and the durability of the neo-squamous epithelium.

Objective：To investigate the expression of cyclooxygenase-2 and its pathological effect in the experimental nonalcoholic fatty liver of rats, and to explore its possible mechanism. Methods：The rat NAFLD model was established by giving a fat-enriched diet. The blood samples were obtained form abdominal aorta and the levels of serum ALT, AST and IL-1, changes in the hepatic tissue 6-k-PGF1 α TXB2 were measured. The expression level of COX-2 in rats livers were assayed by immunohistochemistry, RT-PCR and Westernblot. Results： Light microscope analysis revealed that hepatocytes were injured in the model group and slightly in the treatment group. The levels of serum TXB2 and IL-1 in the fatty liver rats were increased. Compared with the model group, the IL-1 and TXB2 increased significantly（P〈 0.05）, on the contrary, compared with the normal group, the hepatic tissue 6-Keto-prostagland decreased significantly in the model group（P 〈 0.05）, the treatment group also increased but P 〉 0.05. There was no positive expression of COX-2 in hepatic tissue of normal rats. In the model group, there was positive expression of COX-2 antigen and the number of COX positive cells progressively increased at 4, 8, 12 wks. The intensity of expression of COX-2 had significantly increased（P 〈 0.05 ） and the intensity of COX-2 expression in the treated group decreased remarkably compared with the model group（P 〈 0.05）. The expression of COX-2 mRNA and the level of COX-2 protein were significantly stronger in the liver of model rats compared with normal rats, and significantly weaker in treated rats, than in 8W and 12W model rats（P 〈 0.05）. Conclusion：The increase of COX-2 expression in NAFLD is closely associated with the severity of liver inflammation and damage. COX-2 may play an important role in the progression of rat NAFLD, and the expression of COX-2 mRNA is downregulated by cyclooxygenase-2 inhibitor, which can depress the oxidative stress and control inflammatory response efficiently.

员工自我同一性、组织支持感和工作投入度的关系研究

作者： xiaolan lu Siyuan Chen Keyi Zhang School of Business Jianghan University School of Mathematics and Statistics Hubei Normal University

China-U.S. agricultural trade has the characteristics of China’s continuous growth in trade volume with slowing growth and widening deficit. Based on SITC agricultural products data from 1992 to 2016 in UN Comtrade database, extensive margin, price margin and quantity margin of agricultural products exported from China to the United States in different economic periods were calculated, as well as their contribution rates to the growth of agricultural products export share. The research results show that the average extensive margin, price margin and quantity margin are 0.9137, 1.0216 and 0.0312, respectively. It shows that the agricultural products exported from China to the United States cover most tradable agricultural products, and the export price is slightly higher than the average price, while the export quantity accounts for less. The growth sources of China’s agricultural exports to the United States are different in each research stage. In general, the growth of agricultural exports mainly comes from intensive margin growth, and the contribution rate of quantity margin is higher than that of price margin.

员工工作倦怠、离职率高是很多现代企业面临的共同问题,企业通常通过提高工资、福利或给予股票、期权等长期激励的方式来应对,但这些外部刺激并不能长期奏效。本人在阅读文献和人力资源管理实践过程中不断思考和总结,发现不同的个体对于同一环境中的组织支持感甚至都有不小的差异,也就是说即使企业自认为已经很好地对待员工,员工本人如没有相应的成熟度,或者说自我同一性处于某种状态,其工作投入度和最后的工作绩效依然不会高,离职率也不会下降。本文依据自我同一性状态、组织支持感与工作投入度三份量表,通过网络问卷调查并测算了256位不同背景的中国员工自我同一性探索程度(EIE)、自我同一性承诺程度(EIC)、工作投入度(JI)、组织支持感(POS)值。利用SPSS16.0进行统计分析,结果表明:1.个体的自我同一性承诺状态与工作投入度正相关;2.个体的组织支持感与工作投入度正相关;3.个体的组织支持感在自我同一性和工作投入度的关系之中起调节作用,组织支持感每升高一个级别,自我同一性延期支付与自我同一性混乱的的个体工作投入度明显增高;4.个体的性别与自我同一性无显著相关,但个体的年龄与学历与自我同一性显著相关,年龄越大的个体,自我同一性探索越充分,学历越低的个体,自我同一性承诺程度越高;5.个体的年龄、性别、学历与工作投入度无显著相关。
