After the cell growth curves was recorded, RPE cells of the 3-5th passages were utilized. 2、Three different siRNA (siRNAl,siRNA2,siRNA3) targeting against human cx43 gene and one negative control siRNA were designed and transfected into cultured human RPE cells via liposome reagent. The most effective siRNA can be determined by semi-quantitative reverse transcription PCRRT-PCR. 3、To the most effective siRNA, after transfected into human RPEs with different concentration, the cellular proliferate activities were messured by MTT colorimetry ; the percentages of RPE in different cell circle phase was assayed by FCM; the changes of phenotypical properities were observed with SCM; the protein expression of cx43 was studied through immunocytochemistry stain and Weston blot; the communication intercellular was calculated with FRAP; and the ability of recovery was assessed by using an in vitro wound healing model.4、The total proteins of siRNA1 and RPE were seperated by two-dimensional gel electrophoresis and visualized by silver staining. Proteins with significant expression alterations were selected and their peptide mass fingerprints (PMFs were obtained by matrix-assisted laser desorption/ionization time of flying mass spectrometry (MALDI-TOF-MS).The PMFs were used to search NCBInr database by Auto MS-Fit software.

MRI findings usually fall into 2 categories: 1 A soft tissue mass that is hypointense on T1-weighted images and hyperintense on T2-weighted images with diffuse homogeneous or slightly heterogeneous enhancement within the collection; 2 As the phlegmonous mass necroses, there may be a peripherally-enhancing fluid collection.

MRI表现通常被分为两类：1）软组织肿块，T1低信号，T2高信号，病灶内弥漫均匀性或轻度不均匀强化；2）当表现为蜂窝组织炎坏死时，表现为边缘强化的积液。

Visual carbon stars whose mid-infrared spectra are mainly dominated by photospheric continuum and show large excesses at 60um, represent a transition phase which follows an interruption of mass loss from the oxygen-rich phase and begins a new phase of the mass loss of carbon-rich material. Excesses at 60um in these stars are the emission from the residual of oxygen-rich material.

光学碳星的中红外能量主要来自光球，在60μm处存在超量发射，人们认为其演化阶段处在抛射富氧物质终止和新的富碳拱星壳层形成之间，其60μm超量发射就是富氧物质的残余效应。

In obese children, leptin concentration decreased during 4 mo of physical training and increased during a subsequent 4-mo period without physical training, fat mass was highly correlated with baseline leptin, and greater reductions in leptin during 4 mo of physical training were seen in children with higher pretraining leptin and in those whose total mass increased least.

在肥胖小孩中，4mol 周期体力运动使瘦素浓度降低，在接下来不运动的4-mo 周期中，瘦素水平提高。在那些体重增长最慢、运动前瘦素水平高的肥胖小孩中，4-mo 体力运动周期使其瘦素水平降低程度非常明显。第二篇翻译原文全文。pdf (43.99k)杂志，年，卷，期，页

The reseach on activity changes of SOD, POD and CAT during the somatic embryogenesis of Y35 showed:(1) The activty of SOD was from 52.98 to 133.20 U·g-1·h-1, and remained a rising trend after early single embryo forming, this revealed that SOD might be positively correlated to the differentiation of embryogenic cell and the development of somatic embryo.(2) The activty of POD was from 0.05 to 0.50 U·mg-1·min-1, ascended firstly and desceded later, and was highest in embryogenic callus and lowest in late single embryo , this revealed that POD might be positively correlated to the division and differentiation of proembryo mass, while negatively correlated to the development of PEMⅢto late single embryo.(3) The activty of CAT was from 0.86 to 2.81 U·mg-1·min-1, showed an up-down-up trend, reaching to the highest peak at the time of early embryo formating and decreasing to the lowest at the time of early cotyledonary embryo formating, this revealed that CAT might be positively correlated to the development of early single embryo, while negatively correlated to the formation of middle single embryo and early cotyledonary embryo.The changes in activty of SOD, POD and CAT indicated these three antioxidant enzymes coregulated the differentiation and development of embryogenic cells during Larix somatic embryogenesis.4. Differentially expressed cDNA libraries of the stages of proembryo mass and somatic embryo maturation were successfully constructed by suppression subtractive hybridization.

对Y35体细胞胚胎发生过程中抗氧化酶活性变化的研究显示：(1)SOD活性在52.98~133.20 U·g-1·h-1之间，并在早期单胚形成后一直保持上升的趋势，表明其与胚性细胞的分化及体细胞胚的发育均具呈正相关；(2)POD活性在0.05~0.50 U·mg-1·min-1之间，呈现出先下降后升高的趋势，在胚性愈伤组织中最高，而在后期单胚形成时降至最低，表明其与原胚团的分裂和分化呈正相关，但与PEMⅢ向后期单胚的发育呈负相关；(3)CAT活性在0.86~2.81 U·mg-1·min-1之间，表现出升-降-升的变化趋势，在早期单胚形成时升至最高，在早期子叶胚形成时降至最低，表明其与早期单胚的发育呈正相关，而与中期单胚和早期子叶胚的发育呈负相关。

Methods and results LVH was assessed by echocardiographic LV mass index in g/m(2.7 and excess of LV mass (eLVM, in % of the observed value) relative to the amount predicted by sex, stroke work, and height, using a prognostically validated equation in 2078 participants of Cardiovascular Health Study without prevalent MI and normal systolic function.
