This article was to study the potential resistance mechanism of three different wheat varieties （Ww2730, Xiaoyan 22 and Batis） in the seedling stage to Sitobion avenae. The aphid feeding behavior was ascertained by stylet penetration activities monitoring using the electrical penetration graph （EPG） technique. When the aphids feed on Ww2730 seedlings, the time for the 1st duration probing was later than that on Xiaoyan 22 and Batis significantly, and the number of interrupted probing before the 1st duration probing was more than that on Xiaoyan 22 and Batis significantly, and the 1st duration probing was shorter than that on Xiaoyan 22 and Batis significantly. The durations of the stylet pierce from the extra- to the intra-cellular （pd Ⅱ-1） on Ww2730 and Xiaoyan 22 were longer than those on Batis significantly. The duration of the potential drop （pd） in C wave on Ww2730 was longer than that on Xiaoyan 22 and Batis significantly. The times and duration of the G wave （ingestion in xylem） on Ww2730 were more and longer than those on Xiaoyan 22 and Batis significantly. The times of spot G wave on Batis was more than that on Ww2730 significantly, but the duration of spot G was shorter than that on Xiaoyan 22 and Ww2730 significantly. The total time of E1 wave, the longest duration of E1 fractions, and the mean duration time of E1 fractions that followed E2 wave on Xiaoyan 22 and Batis were all significantly longer than those on Ww2730. There was no difference of the mean duration of the 1st E1 wave on the 3 varieties, but the mean durations of other E1 wave on Ww2730 and Xiaoyan 22 were shorter than those on Batis significantly. The other wave parameters, including times and durations of F and E2 were all not different on the 3 wheat varieties. It is suggested that the resistance mechanism of wheat variety Ww2730 to S. avenae is a restriction factor of feeding in epidermis, the thicker cell wall in mesophyll, and secondary metabolites or nutrition unbalance in phloem in

The results of cyclization reaction between chloropentafluorobenzene and bifunctionalnucleophiles such as XCH2CH2OH（X =OH, NHMe, NHEt） and HN （CH2CH2OH）2, NH2CH2CH2NH2were reported. It was found that the NaH/DMF system was a better reagent for the preparation ofsodium alcoholates and the yields of cyclic products ranged from 50-80% which were muchhigher than that reported by previous workers.3

世界卫生组织的宪章和有关卫生大会的决议多次指出“人人享有最高而可获得的健康标准是一项人类的基本权利”。中国曾经是发展中国家贯彻世界卫生组织人人享有卫生保健战略目标的楷模。随着社会经济的发展,人口结构及疾病谱的改变,科技的迅速进步,我们需要进行卫生改革,但世界上没有现成的模式。分析了我国的卫生改革中取得的伟大成就,但在医疗卫生改革中缺乏伦理考量卫生资源分配的不公正和政府在卫生总投入中所占的比例不足,是造成“看病难、看病贵”的主要原因。由世界卫生组织和联合国教科文组织最近所提出的伦理准则分析了卫生改革的公正性和社会责任。

Background Few studies have evaluated late clinical outcome of no-patch technique in patients with large left ventricular aneurysms. The objectives of this study were to evaluate a no-patch surgical technique to reconstruct the left ventricle in patients with left ventricular aneurysm and to assess early and late clinical *** In 1995, we began using a no-patch technique in patients with dyskinetic left ventricular aneurysms. A total of 145 patients underwent left ventricular reconstruction with this technique and were followed up for （59±29） months （range,1-127 months）. Risk factors for early mortality were analyzed by bivariate analyses. Cox＇s proportional hazards model was used to calculate risk factors for all-cause mortality and hospital readmission. Kaplan-Meier methodology was used to analyze late *** One week after operation, left ventricular end-diastolic diameter had decreased from （61±8） mm to （55±8）mm, and geometry of the left ventricle was restored to a more normal conical shape. Early mortality was 3% and late mortality 11%. Over a 5-year follow-up period, hospital readmission was 28%. One-, 5-, and 10-year survival estimates were 95% （95% confidence interval （CI） 91%-99%）, 86% （95% CI 78%-94%）, and 74% （95% CI 60%-88%）.Readmission-free survival at 1 and 5 years after operation was 87% （95% CI81%-93%） and 60% （95% CI50%-70%）,*** The no-patch technique for left ventricular reconstruction is an effective and simple procedure that can achieve satisfactory early and late clinical outcomes in patients with left ventricular aneurysms.

供应链企业的公平关切是发展与维持良好供应链上下游合作关系的重要因素。面对消费者的低碳偏好与碳排放规制约束,供应链企业在确定最优定价与减排水平等运作决策时,常常表现较强的公平关切倾向。探究环保规制下公平关切如何影响供应链的运作决策,可以为供应链合作提供对策。本文在碳限额与碳交易机制下,研究了由公平关切制造商和公平关切零售商组成的低碳供应链的最优定价和碳减排率等决策,分析了公平关切对最优定价和碳减排水平及利润的影响,并讨论了收益共享-成本共担契约模型对供应链的协调性,最后通过数值仿真验证了主要结论。结果表明:(1)制造商和零售商都公平关切时,收益共享-成本共担契约的参数若满足一定条件,供应链可以实现协调。(2)批发价与制造商公平关切系数正相关,零售价与制造商和零售商公平关切系数都正相关;若制造商考虑零售商公平关切则批发价的变化取决于碳减排成本系数的大小,碳减排率与制造商和零售商的公平关切系数是负相关;若制造商忽视零售商的公平关切,则批发价仅受制造商自身公平关切的影响,碳减排率与制造商公平关切负相关,与零售商公平关切无关。(3)制造商公平关切对双方利润具有负向影响,零售商公平关切对制造商利润也有负向影响,而零售商利润随自身公平关切的变化情况取决于制造商是否考虑其公平关切,若考虑则两者正相关,否则两者负相关。
