Planetary nebulae （PNe） are good tracers of the stellar populations, chemical composition and dynamics of their host galaxies. This paper reports the discovery of new PNe in the outskirts of the Andromeda Galaxy （M31） with the Guoshoujing Telescope （GSJT, formerly named the Large Sky Area Multi-Object Fiber Spectroscopic Telescope-LAMOST） during its early commissioning phase. In total, 36 candidates selected from SDSS photometry are confirmed in terms of their PN nature, including 17 new discoveries and another 19 previously known emission line objects. Their positions, spectra, radial velocities and m5007 magnitudes are presented. We discuss the potential for detecting more PNe in M 31 with GSJT＇s multi-object spectroscopy and the related applications in studies of the dynamics and chemistry of M 31 and its assemblage history.

We present preliminary analyses of spectra of quasar candidates in two Guoshoujing Telescope （GSJT, formerly named the Large Sky Area Multi-Object Fiber Spectroscopic Telescope - LAMOST） test fields near M 31 where one is close to the optical center of the disk and the other is towards the northeastern outskirts of the halo, obtained during the early stage of the GSJT commissioning in the last season of 2009. Both fields contain background low-redshift quasar candidates selected from the SDSS photometry. In total, 14 new quasars with redshifts up to 2 and i magnitudes between 16.7 and 19.2, are discovered, including 7 within the 2.5° central region of M 31. We briefly discuss the potential applications of these newly discovered bright quasars.

“健康和疾病的发育起源”假说提出:除了遗传和环境因素,生命早期(包括胎儿和婴幼儿时期)的不利因素会增加成年后罹患慢性疾病的风险。表观遗传修饰可能是生命早期经历营养不良导致成年后发生代谢紊乱的潜在机制。因此,母体孕期若有营养不良(如热量摄入过少或铁、叶酸等微量营养素缺乏)、肥胖、高血糖等,可能通过表观遗传机制增加子代成年后慢性代谢性疾病的易感性。最新研究表明,生命早期不论是经历营养不良,还是营养过剩,都会影响成年后肝脏、骨骼肌、血液等组织中调控糖脂代谢相关microRNA的表达。基于此,以下重点介绍作为表观遗传机制之一的microRNA,在母体孕期营养不良状态下可能导致子代脂质代谢异常的潜在机制,以期为以非酒精性脂肪性肝病为代表的脂代谢紊乱疾病的发生机制以及生命早期干预治疗提供科学依据。
