均质

The results show that the initial phase is non-homogeneous reaction,solid-liquid mass transfer coefficient is the main factor on the reaction rate,N-methyl-2-pyrrolidone can accelerate the dissolution of polyester film and prompte the alcoholysis reaction into homogeneous process.

结果表明，反应初始阶段为非均相阶段，固-液间传质系数是影响反应速率的主要因素，加入NMP可以加速PET的溶解，促使醇解反应快速进入均相阶段。

Although there is a little carbonite caused by some magmatic dikes in the CarboniferousPermiam coal, most Carboniferous-Permian coal has no great differences in vitrinite reflectance, crystalline indices, bulk specific gravity, hardness, and the content of velotile matter from the Jurassic coal, and both are super-anthracite.

区内石炭—二叠系煤与侏罗系煤除了前者含有一些由侵入体造成的天然焦或半焦外，二者均为超无烟煤，在镜质体反射率、煤晶核结构、显微硬度、挥发份和容重等方面上均没有明显的差异，说明区域变质是在煤系地层沉积之后发生的。

Results Pulmonary carcinosarcoma and blastoma both were found to be rare malignant tumors, and both epithelial and mesenchymal elements can be seen under the microscopy with different characteristic features.

The expression level of metabolitic enzyme (CYP1A1, CYP1B1) and its correlation with cell differentiation /apoptosis were studied as well. The influence of resveratrol in cell cycle was determined with FCM. Results 1 Resveratrol not only suppresses the growth of medulloblastoma cells in a dose and time related fashion but also induces cell differentiation and apoptosis. Resveratrol promotes differention of UW228-1,-2 cells to forward glia, UW228-3 and Med-3 cells to neuron. A treatment of resveratrol in the concentration of 100μM for 48hrs comit most of cells die of apoptosis. 2 Among the four cell lines Fas and Caspase-3 were constantly expessed, whereas FasL was absent irrespective to the drug treatment. 3 ICC, RT-PCR, Western-blot hybridization and EROD enzymatic activity assay demonstrated that expression of CYP1A1 is different after treatment with resveratrol in four cell lines, up-regulated in three UW228 cell lines in a dose dependent manner but down-regulated in Med-3 cells. Suppressive effect of resveratrol on CYP1B1 expression is the same among four medulloblatoma cell lines. 4 Cell cycle distribution of UW228-3 was greatly changed after treatment.

结果：1、白藜芦醇以时间和剂量依赖性方式抑制髓母细胞瘤细胞生长，同时促进细胞的分化和凋亡：白藜芦醇促使UW228-1、-2靶细胞向神经胶质细胞方向成熟分化，UW228-3、Med-3细胞向神经元细胞方向成熟分化，以100μM作用48小时效果显著；2、四个细胞系均有Fas和Caspase-3表达，但无Fas-L基因表达和蛋白活性产生，因此难以形成Fas相关性死亡通路；3、白藜芦醇处理前后CYP1A1基因的表达在各细胞系略有不同：UW228-1，-2，-3三个细胞系白藜芦醇以剂量相关性方式上调CYP1A1的表达，而Med-3细胞系，白藜芦醇却抑制CYP1A1的表达；四个细胞系在白藜芦醇处理后CYP1B1的表达均受到抑制；4、UW228-3细胞系经白藜芦醇作用后细胞周期有较大改变，表现在G0/G1期在整个细胞周期中所占的比例增加，而其它时期则相应减少。

The absorption of root system was the main sources of nitrogen in the plant.The effects of matrix ventilation on the abaorption,transportion and metabolism of nitrogen in the root system of cucmber were discussed deeply.The results showed that contents of ammonium,nitrate,free amino acids and soluble protein in cucumber roots were higher in G1 treatment.Contents of ammonium,nitrate and free amino acids in cucumber roots were the trend of the dropping after the first rising in F1 treatment,but contents of soluble protein was lower11.03%than that of the control.

根系吸收是植物体内氮素的主要来源，本研究深入探讨了基质通气状况对黄瓜根系氮素吸收、运输和氮代谢的影响，结果表明G1通气处理根系的铵盐、硝酸盐、游离氨基酸和可溶性蛋白含量均较高；非通气处理(F1处理)根系内铵盐、硝酸盐和游离氨基酸含量呈先升高后降低的趋势，而可溶性蛋白含量始终较低，比对照降低11.03%。G1处理根系硝酸还原酶、亚硝酸还原酶、谷草转氨酶、谷丙转氨酶、谷氨酰胺合成酶活性均较高；而F1处理的酶活性在处理末期显著降低，其中谷氨酰胺合成酶活性比对照降低33.33%。

PSE7 and SOJB had the similar binding proteins in tobacco, suggesting that they may share some similar biological functions. The ubiquitin-conjugating protein and peptidase involved in protein degradation were found binding with SOJB but not PSE7. Both SOJB and PSE7 could bind with transmembrane transport protein, SOJB bound with copper transporter protein, and PSE7 bound with water channel protein. The results suggested that the target of SOJB and PSE7 may be located in cytoplast.

PSE7和SOJB在烟草中存在几个相似的结合蛋白，表明二者具有共享的生物学功能；SOJB能与肽酶和泛素结合蛋白（与蛋白质降解有密切关系）互作，而PSE7没有筛选到类似蛋白；SOJB和PSE7均能与跨膜运输蛋白结合，PSE7与水通道蛋白结合，SOJB与铜离子转运蛋白结合，表明二者在胞质内均存在作用靶标。

Results Stable drug-resistant SW1990/GZ cell strain was established by culturing with gemcitabine for 9 months. The morphology and growth characteristics of the cell strain changed remarkably. The cells shrinked and became rounder; its endoplasm expanded; granular substances increased; and the doubling-time was prolonged. Resistance of the cell line to gemcitabine, fluorouracil, adriamycin, and mitomycin significantly increased. The TrxR activity of the drug-resistant cells was increased markedly.

结果 药物培养9个月后，得到稳定传代的SW1990/GZ耐药细胞株；其形态学、生长特征等均发生了明显变化，细胞变圆、体积缩小、内质网扩张、颗粒样物质增多及细胞倍增时间延长；对吉西他滨、5-氟尿嘧啶、阿霉素和丝裂霉素的耐药性均显著增加；耐药细胞的TrxR活性也明显增高。

I am saved at that time " examine immediately " basic characteristic is: 1Of.1POCT cover a range wide, the testing instrument model of same item amounts to 7~8 to plant. 1.2POCT all is placed in clinical the outpatient service of each division, emergency call and ward, the apparatus is almost entire by groom without POCT operation post already card, lack again examine the operation of the member that be not identifier of basic knowledge. 1.3POCT assures measure without quality, examine the specimen is collected, reagent is purchased and save all compare optional, be opposite extremely between the instrument experiment, do not have room endoplasm to accuse already at ordinary times, do not have again judge character between the room, examine quality is in nobody to run state. Of 1.4POCT detect result error is big, repeatability of partial instrument result is poor, the hospital examined 2002 3 hospitals selectived examination randomly in division quality assessment, 45 second large biochemistry appearance detects contrasting POCT blood sugar, its written guarantee...

当时我省"即时检验"的基本特征是：1.1POCT的覆盖面广，同一项目的检测仪器型号多达7~8种。1.2POCT均放置在临床各科的门诊、急诊和病房，仪器几乎全由既无POCT操作岗位培训证，又缺少检验基本知识的非检验人员操作。1.3POCT没有质量保证办法，检验标本采集、试剂采购和保存均比较随意，仪器间无比对试验，平时既无室内质控，又无室间质评，检验质量处于无人管理状态。1.4POCT的检测结果误差大，部分仪器结果重复性差，2002年医院检验科质量考核中随机抽查了3所医院，45例次有大型生化仪检测对照的POCT血糖，其结。。。

A schematic model was proposed to illustrate the occurrences of various lithologies and lithofacies associations. The erosional surfaces on siliciclastic mudstones, funnel-shaped structure, and the exhuming of massive cold-seep carbonates exposed might have been occurred concurrently during a tectonic unstable time in SW Taiwan. The deposition of fossiliferous mudstone interfingered with the conglomerate lithofacies, and represented the rapid facies transition from siliciclastic (non-carbonate) into carbonate environment.

综合岩相观察结果，建构一个符合台湾西南部更新世珊瑚礁与基底泥岩接触关系的沉积相模式；其中，基底泥岩顶部的不规则冲蚀面、充填碳酸盐胶结泥岩砾与碳酸岩烟柱的漏斗状沉积，以及块状冷泉碳酸盐岩的出露，可能均为区域地质构造活动时期所造成；至於与含化石泥岩同时沉积的砾岩相，可能均为基底泥岩在快速浅化的过程中所沉积，标志古环境由矽质碎屑快速转变为碳酸盐环境的过程。
