北羌塘盆地位于青藏高原的中部,属东特提斯构造域,是一个具有成盐远景的蒸发岩盆地。前人对盆地的研究多局限于层序地层、构造运动、油气成藏等,对于盆地内蒸发岩的研究,特别是其成矿流体来源的研究报道较少。文章通过对北羌塘盆地龙尾湖QY-1钻孔中硬石膏岩层锶同位素进行测定,首次对盆地中侏罗统夏里组蒸发岩成矿流体的来源进行探讨。结果表明,笔者所分析的样品的锶同位素比值变化范围为0.707475~0.709048,均值0.708331,与同时期全球海水锶同位素比值(0.706860~0.707081)相比略高,表明成矿流体来源主要是海水。结合前人对羌塘盆地构造运动与盆地演化的认识,认为陆源锶的输入造成了本区的锶同位素比值高于同期海水。此外,钻孔中的同位素组成与前人公布的全球中侏罗世(164~160.2 Ma)海水锶同位素曲线具有较好的对比性,中晚侏罗世羌塘盆地海侵海退作用的强弱是控制盆地夏里组锶同位素演化的主要因素。

高温地热水中含有丰富的锂资源,世界各国对其中锂资源的开发利用的研究越来越多。对青藏高原丰富的地热资源中富锂地热资源进行了综述,得出其具有以下特点:(1)构造控制强烈,地热型锂资源主要分布在雅江缝合带两侧及其南部地区强烈活动的高温地热田中,受到沿近NS向正断层发育的裂谷或地堑盆地的强烈控制;(2)品质好,锂含量可高达239 mg/L;Mg/Li非常低,多数富锂地热系统Mg/Li介于0.03~1.48;Li/TDS相对较高且介于0.25%~1.14%(扎布耶富锂盐湖为0.19%;玻利维亚乌尤尼盐湖为0.08%~0.31%);持续稳定排放数十年,部分达到工业品位(32.74 mg/L);伴生可以综合利用的B、Cs和Rb元素等;(3)规模大:据不完全统计,当前锂含量达到或超过19 mg/L的富锂温泉至少有19处,年排出金属锂约4281 t,折合碳酸锂25686 t,并且最新钻孔数据表明地热田深部潜力巨大;(4)属于非火山型,火山岩缺失;(5)深部来源成因,富锂地热系统的形成与印度和欧亚大陆碰撞引起的地壳深部部分熔融密切相关,深部熔融岩浆为富锂地热系统提供了稳定的热源,富锂的母地热流体沿着青藏高原南部广泛发育的断裂带上涌至地表形成高温富锂热泉。由此,认为青藏高原南部广泛发育的高温富锂地热资源是一种非常有价值、值得开发利用的地热型锂资源,随着地热水中锂提取技术的不断提升,青藏高原南部地热型锂资源有望成为一种可有效开发利用的锂矿床新类型——地热型锂矿床。

Cloning non-HUMAN primates by somatic cell nuclear transfer

引用

Science China(Life Sciences) 2018年第3期61卷 361-362页

作者： shaorong Gao Clinical and Translational Research Center of Shanghai First Maternity and Infant Hospital School of Life Sciences and Technology Tongji University

The recent breakthrough in successful producing cloned non- human primates by somatic cell nuclear transfer （SCNT） has attracted great attention both scientifically and publically （Liu et al., 2018）. Two macaque monkeys, named ＂Zhongzhong＂ and ＂Huahua＂, were cloned from fetal fi- broblast cells by Chinese scientists using the technique that produced the first cloned mammal ＂Dolly＂ 21 years ago （Wilmut et al., 1997）. The first cloned sheep has re- volutionized our thinking that the mammalian somatic cells can be reprogrammed into totipotent embryos by SCNT, although the efficiency is extremely low. Actually, in the same year when ＂Dolly＂ was reported, a paper published in Biology of Reproduction also attracted broad attention in which two rhesus monkeys were produced from blastomeres isolated from 4-cell stage embryos using the same technique （Meng et al., 1997）. However, it remains very challenging if the somatic cells from monkeys can be reprogrammed into totipotent embryos, although many laboratories all over the world have tried very hard in the past 20 years. Indeed, the successful cloning of monkeys today is attributed to both the technical improvement and the progress obtained in me- chanistic studies in reprogramming. Two major techniques are involved in SCNT. The first is called enucleation through which the spindle-chromosome complex （SCC） of an oocyte at metaphase II （MII） stage is removed by an enucleation pipette. The enucleation process is relatively easy for mouse oocytes since the SCC can be visualized under light micro- scope, but the SCC of oocytes from large animals including

Progress in understanding epigenetic remodeling during induced pluripotency

引用

Science Bulletin 2015年第20期60卷 1713-1721页

作者： Rui Gao Xiaoyu Liu shaorong Gao Clinical and Translational Research Center of Shanghai First Maternity and Infant Hospital School of Life Sciences and Technology Tongji University School of Life Sciences Tsinghua University National Institute of Biological Sciences

Over 50 years of efforts, cellular reprogram- ruing opens a new door for disease modeling and regen- erative medicine. Although induction of pluripotency by transcription factors has become common, only a small portion of basic mechanisms of epigenetic modifications during this process have been revealed. To clearly under- stand reprogramming and devise ways to promote full transition towards pluripotency, we must gain insight from comprehensive characterizations of cells at distinct repro- gramming stages, which involves gene expression profil- ing, chromatin state maps of key activating and repressive marks, and DNA modifications. Here, we review recent advances in epigenetic reprogramming to pluripotency with a focus on the principal molecular regulators and attach importance to the combination of high-throughput sequencing and systematic biology approaches in uncov- ering underlying molecular mechanisms of this unique platform in future researches.

Pluripotency of induced pluripotent stem cells

引用

Journal of Animal Science and Biotechnology 2012年第1期3卷 3-9页

作者： Lan Kang shaorong Gao National Institute of Biological Sciences NIBSBeijing102206China

Recent studies have demonstrated that differentiated somatic cells from various mammalian species can be reprogrammed into induced pluripotent stem （iPS） cells by the ectopic expression of four transcription factors that are highly expressed in embryonic stem （ES） cells. The generation of patient-specific iPS cells directly from somatic cells without using oocytes or embryos holds great promise for curing numerous diseases that are currently unresponsive to traditional clinical approaches. However, some recent studies have argued that various iPS cell lines may still retain certain epigenetic memories that are inherited from the somatic cells. Such observations have raised concerns regarding the safety and efficacy of using iPS cell derivatives for clinical applications. Recently, our study demonstrated full pluripotency of mouse iPS cells by tetraploid complementation, indicating that it is possible to obtain fully reprogrammed iPS cells directly from differentiated somatic cells. Therefore, we propose in this review that further comprehensive studies of both mouse and human iPS cells are required so that additional information will be available for evaluating the quality of human iPS cells.

Stress fields caused by a dislocation in an anisotropic 3-layer system

引用

Science China(Physics,Mechanics & Astronomy) 2011年第3期54卷 542-551页

作者： WANG HuYi YIN YiHui YU shaorong Institute of Structural Mechanics China Academy of Engineering Physics Mianyang 621900 China

We investigated the stress fields caused by a dislocation in an anisotropic 3-layer system. Based on the image method, the original 3-layer system is firstly decomposed into three infinite homogenous systems. The image dislocation densities used as unknowns are then strategically distributed in order to satisfy the boundary conditions. The resulting governing equations are singular Cauchy integral ones. Removing the singular terms yields non-linear Fredhom integral equations of the second kind. The obtained stress fields satisfy the boundary conditions, i.e., the traction free condition on the free surface and continuous conditions across the interfaces. Also, a comparison with previous results is made and good agreement is achieved. Numerical investigations show that under the plain strain condition, layer thickness and dislocation position play stronger roles in the stress fields than crystallographic orientation, and these effects more significantly affect the stress fields caused by an edge dislocation than by a screw dislocation.

Ultra_weak chemiluminescence sent forth by animals’ organs, tissures and cell organs is discussed. It is indicated that if the ultra_weak chemiluminescence of an animal is high, its metabolism is exuberant, and its pregnant rate is high. A study of the influence of ligh voltage static electric field on the luminescence of sheep sperm is carried out.
