Objective:To investigate the effects of T-2 toxin on expressions of Fas,p53,Bcl-xL,Bcl-2,Bax and caspase-3 on human ***:Human chondrocytes were treated with T-2 toxin(1～20 ng/ml)for 5 ***,p53 and other apoptosis-related proteins such as Bax,Bcl-2,Bcl-xL,caspase-3 were determined by Western blot analysis and their mRNA expressions were determined by reverse transcriptase-polymerase chain reaction(RT-PCR).Results:Increases in Fas,p53 and the pro-apoptotic factor Bax protein and mRNA expressions and a decrease of the anti-apoptotic factor Bcl-xL were observed in a dose-dependent manner after exposures to 1～20 ng/ml T-2 toxin,while the expression of the anti-apoptotic factor Bcl-2 was ***,T-2 toxin could also up-regulate the expressions of both pro-caspase-3 and caspase-3 in a dose-dependent ***:These data suggest a possible underlying molecular mechanism for T-2 toxin to induce the apoptosis sig- naling pathway in human chondrocytes by regulation of apoptosis-related proteins.

目的观察针刺干预72 h后脑缺血再灌注损伤(CIRI)大鼠缺血侧海马区miR-29a-3p、miR-29b-3p的表达,探讨针刺促CIRI修复的机制。方法30只SD大鼠随机分为假手术组、模型组和针刺组,每组10只,造模组大鼠使用线栓法制备CIRI模型,假手术组只剥离血管不插入线栓;假手术组和模型组只捆绑不针刺,针刺组捆绑后针刺“大椎”“百会”“水沟”穴,一天治疗两次,共治疗7次。采用Garcia评分法对神经功能进行评定,TTC染色法检测脑梗死面积比,qRT-PCR法检测缺血侧海马区miR-29a-3p、miR-29b-3p的表达。结果干预前与假手术组比较,造模组Garcia评分显著降低(P<0.01),脑梗死面积比显著增加(P<0.01),患侧海马区miR-29a-3p、miR-29b-3p表达量降低(P<0.05,P<0.01);干预72h后与模型组比较,针刺组Garcia评分明显上升(P<0.01),脑梗死面积比显著下降(P<0.01),患侧海马组织miR-29a-3p、miR-29b-3p的表达量明显增加(P<0.01)。结论针刺可减少CIRI大鼠缺血侧脑梗死面积、改善神经功能损伤、发挥脑保护作用,可能与干预72h后上调缺血侧海马区miR-29a-3p、miR-29b-3p表达有关。

In this study, the effect of icariin, a flavonoid from the Chinese traditional medicine epimedium, on miRNA-21 of mouse developmental blastocysts in vitro and the development of preimplantation embryos were studied. The possible effective targets of icariin promoting preimplantation embryo development in vitro and anti-apoptosis were determined. The embryos were cultured in modified CZB medium （mCZB） as control group. The experimental group （Ica group） was supplemented with 0.6 μg mL-1 icariin. Mouse pronuclear embryos were cultured in vitro until blastocysts. The development rates of preimplantation embryos were observed. The total cell number, apoptotic cell number and the rate of apoptotic cells in blastocysts were analysed by the staining of Hoechst33342 and labeling of TUNEL and detected under a laser confocal scanning microscope. The miRNA-21 expression, the mRNA levels of pro-apoptotic Caspase3, and the target genes of miRNA-21： pro-apoptotic PTEN, anti-apoptotic Bcl-2 were detected by real-time RT-PCR. The results showed that percentages of morulaes and blastocysts in Ica group were both extremely higher than control group （（85.14±6.57）% vs. （72.04±11.58）%; （82.50±7.11）% vs. （66.80±11.70）%, respectively, P〈0.01）. The total cell number ofblastocysts had extreme difference between Ica group and control group （（61.40±9.64） vs. （46.23±4.50）, P〈0.01）. The apoptotic cell number and rate of apoptotic cells of blastocysts were both reduced in Ica group （（1.47±0.51） vs. （2.94±0.66）; （2.40±0.27）% vs. （6.25±0.62）%, respectively, P〈0.01）. Compared to control group, addition of icariin into mCZB extremely increased the expression of anti-apoptotic miRNA-21 （P〈0.01）, down-regulated pro-apoptotic Caspase3 （P〈0.05） and PTEN （P〈0.01）, up-regulated anti-apoptotic Bcl-2 （P〈0.01）. In conclusion, icariin could reduce the apoptosis, promote the embryo development in vitro by enhancing miRNA-21 expression to up-regulated anti-apoptotic genes and down-regulated pro- apoptotic genes

目的探讨T-2毒素对软骨细胞主要间质成分Ⅱ型胶原蛋白和蛋白聚糖合成的影响和硒的保护作用。方法采用 MTT法检测T-2毒素对软骨细胞存活率的影响;用TB染色法检测人软骨细胞蛋白聚糖表达;免疫组织化学检测人软骨细胞胶原蛋白Ⅱ表达;RT-PCR检测人软骨细胞Ⅱ型胶原蛋白和蛋白聚糖mRNA表达。结果 T-2毒素在浓度为 0．001-2 mg／L的范围内,对软骨细胞的作用呈较典型的浓度依赖关系和时间依赖关系,而且随着作用时间的延长,浓度依赖关系更加明显。T-2毒素(10～20μg／L)可以抑制软骨细胞Ⅱ型胶原蛋白和蛋白聚糖的合成及其mRNA表达。而加硒能较明显刺激软骨细胞蛋白聚糖mRNA表达,部分减弱T-2毒素的这种抑制,有一定的保护作用,但不显示对T-2 毒素引起的Ⅱ型胶原蛋白及其mRNA表达的保护作用。结论 T-2毒素对软骨细胞Ⅱ型胶原蛋白和蛋白聚糖合成有明显的抑制作用,微量元素硒对T-2毒素引起的软骨细胞蛋白聚糖改变有一定保护作用。

The Large sky Area Multi-Object Fiber Spectroscopic Telescope（LAMOST） general survey is a spectroscopic survey that will eventually cover approximately half of the celestial sphere and collect 10 million spectra of stars, galaxies and QSOs. Objects in both the pilot survey and the first year regular survey are included in the LAMOST DR1. The pilot survey started in October 2011 and ended in june 2012, and the data have been released to the public as the LAMOST Pilot Data Release in August 2012. The regular survey started in September 2012, and completed its first year of operation in june 2013. The LAMOST DR1 includes a total of 1202 plates containing 2 955 336 spectra, of which 1 790 879 spectra have observed signalto-noise ratio（SNR） ≥ 10. All data with SNR ≥ 2 are formally released as LAMOST DR1 under the LAMOST data policy. This data release contains a total of 2 204 696 spectra, of which 1 944 329 are stellar spectra, 12 082 are galaxy spectra and 5017 are quasars. The DR1 not only includes spectra, but also three stellar catalogs with measured parameters： late A,FGK-type stars with high quality spectra（1 061 918 entries）, A-type stars（100 073 entries）, and M-type stars（121 522 entries）. This paper introduces the survey design, the observational and instrumental limitations, data reduction and analysis, and some caveats. A description of the FITS structure of spectral files and parameter catalogs is also provided.

微量元素是构成机体组织的重要成分,并参与体内的物质代谢,对提高饲料营养物质的利用率、防止营养缺乏病有重要意义。并且微量元素作为酶的组成成分,以辅酶或激活剂形式参与机体的生化免疫过程,与动物的生长发育、抗氧化免疫、机体代谢等功能密切相关。微量元素缺乏会导致动物生理结构紊乱。而动物机体自身不能合成微量元素,因而需要在日粮中添加适量的微量元素以满足其生产所需。因此本文综合阐述了有机微量元素(锰、铁、铜、锌、钴、硒)的特点及作用机制,并全面分析了上述有机微量元素或复合物对奶牛生产性能、免疫指标和抗氧化指标、血清微量元素的影响及作用机制,为后续相关研究和奶牛生产提供参考。
