The method is characterized in that:(1) the reflux of the 2-[N, N- 2amino]-3-cyano-group-4-thiopheneacetic-5-carboxylic acid tetra ester is carried out in the proper sodium hydroxide aqueous solution of alcohol for 5h to 6h and the pH value is kept over 10 during hydrolysis;(2) the ethanol of 20 per cent to 60 per cent is added and then the strontium chloride aqueous solution with 2times to 2.5times molal weight is directly added, precipitates the crystal, is filtered and dried;(3) water is added to carry out the reflux and the little salt packed in the crude product is removed, and the product is collected through heat filtration.

其特征在于：①将2--3-氰基-4-羧甲基噻吩-5-羧酸四酯在适量氢氧化钠水醇溶液中回流5～6小时，水解过程保持pH值10以上；②然后再加入20-60％乙醇，随后直接加入2-2.5倍摩尔量氯化锶水溶液，析出结晶，过滤，晾干；③加水回流，除去粗品中包裹少量盐，热过滤，收集产品。

In this study, isobaric tags for relative and absolute quantification labeling coupled with two-dimensional liquid chromatography-tandem mass spectrometry (2D-LC-MS/MS) was employed to compare the differential protein expressions in MCF7 cells upon 17β-oestradiol (E2) stimulation or serum deprivation versus in normal conditions. A total of 576 proteins with the confidential level of ≥95% were identified, 26 proteins among the 576 proteins were found to be differentially expressed after E2 stimulation or serum deprivation, and among them 10 proteins were up-regulated and 16 proteins were down-regulated by more than two folds.

利用四重用于相对和绝对定量的等量异位标签(isobaric tags for relative and absolute quantification， iTRAQ)标记结合二维液相色谱-串联质谱(two-dimensional liquid chromatography-tandem mass spectrometry， 2D-LC-MS/MS)对雌二醇(17β-oestradiol， E2)和血清各自以及共同作用对MCF7乳腺癌细胞内蛋白质表达的影响进行了比较，共鉴定到置信度在95%以上的蛋白质576种，其中各组相对于正常培养组的细胞共找到26种差异在1倍以上的蛋白质，其中10种上调，16种下调。

The nickel, lead, cadmium and mercury ions were pre-column derived by tera-(2-aminophenyl)-porphine (T2APP). These chelates were enriched by solid phase extraction with C18 cartridge and the enrichment factor of 50 was achieved.

中草药样品用微波消化，样品消化液中的镍、铅、镉、汞用四－－卟啉(T2APP)柱前衍生，然后用ZORBAX RP18固相萃取小柱萃取富集镍、铅、镉、汞的T2-APP络合物，富集倍数为50倍；经富集后的络合物用乙腈和0.05mol？

All study subjects underwent a physical and neurologic examination, psychiatric review, laboratory blood studies, and psychoneurological testing. T2- weighted brain magnetic resonance imaging and proton density scans were used to measure aggregate WMH volume.

Schretlen医师和同事最近的研究着眼于65岁以上成人血清UA与认知功能之间的关系，在测量行进速度、语言记忆以及操作记忆时，发现那些UA值高于正常值者，在研究对象中位于最低之四分位的机会高出2.7到5.9倍。

Results showed that the optimum extraction conditions are that extract with ethanol for four hours, soak the remains with boiled water for 40min, repeat 3 times, sedimentate with 2 times volume ethanol; the content of tea polysaccharides is increasing with the fermentation time in different piles of Yunnan Pu-erh tea, 0.45% tea polysaccharides obtained in the first pile, and 1.68% in the forth pile.

试验证明：最佳提取工艺为无水乙醇浸提4h，取茶渣，沸水提取40min，重复3次，2倍体积无水乙醇沉淀；&涯堆&是普洱茶制作过程中的一道特殊工序，是形成普洱茶品质特征最关键的一步，翻堆样中茶叶渥堆时间越长，茶多糖含量越高，一翻堆含量仅0.45%，到四翻堆上升到1.68%，以上均为干物质计。
