| 1 | 同源异盒基因BP_1在肺癌组织中的表达及临床意义显示文摘目的本研究通过对BP1mRNA在肺癌组织中的表达状况的研究,探讨BP1mRNA在肺癌中的表达水平以及和肺癌的临床关系。方法采用逆转录聚合酶链反应(RT-PCR)技术,检测46例肺癌病人的癌组织,相应的癌旁组织和正常组织标本中BP1mRNA的表达程度及意义。结果在46组标本中,肺癌组织中有36例BP1mRNA呈阳性表达(78.26%),癌旁组织6例呈阳性表达(13.04%),正常组织中未检出阳性表达。癌组织,癌旁组织和正常组织中BP1mRNA的表达率之间存在显著性差异(P<0.01)。癌旁组织和正常组织中BP1基因的表达率之间无显著性差异(P>0.05)。在21例高分化标本中13例呈中高表达,25例低分化标本中22例呈中高表达,两者之间存在显著性差异(P<0.01);在20例Ⅰ-Ⅱ期肺癌标本中12例BP1基因呈中高表达,26例Ⅲ-Ⅳ期标本中15例呈中高表达,两者之间无显著性差异(P>0.05)。BP1基因的表达程度在24例鳞癌中21例呈高表达,在22例腺癌中19例呈高表达,两者之间无显著性差异(P>0.05)。结论BP1mRNA在肺癌组织中的表达显著上调;BP1基因的表达可能与肺癌分化程度有关,与病理类型和TNM分期无关。 | 线胤生 党诚学 阎春霞 李和平 Sidney W.Fu 王作仁 | 2006 | 南方医科大学学报2006，26，8： | 4 |
| 2 | The Lobster Eye Imager for Astronomy Onboard the SATech-01 Satellite显示文摘The Lobster Eye Imager for Astronomy(LEIA),a pathfinder of the Wide-field X-ray Telescope of the Einstein Probe mission,was successfully launched onboard the SATech-01 satellite of the Chinese Academy of Sciences on2022 July 27.In this paper,we introduce the design and on-ground test results of the LEIA instrument.Using stateof-the-art Micro-Pore Optics(MPO),a wide field of view of 346 square degrees(18.6°×18.6°)of the X-ray imager is realized.An optical assembly composed of 36 MPO chips is used to focus incident X-ray photons,and four large-format complementary metal-oxide semiconductor(CMOS)sensors,each of size 6 cm×6 cm,are used as the focal plane detectors.The instrument has an angular resolution of 4’-8’(in terms of FWHM)for the central focal spot of the point-spread function,and an effective area of 2-3 cm^(2) at 1 keV in essentially all the directions within the field of view.The detection passband is 0.5-4 keV in soft X-rays and the sensitivity is2-3×10^(-11) erg s^(-1) cm^(-2)(about 1 milliCrab)with a 1000 s observation.The total weight of LEIA is 56 kg and the power is 85 W.The satellite,with a design lifetime of 2 yr,operates in a Sun-synchronous orbit of 500 km with an orbital period of 95 minutes.LEIA is paving the way for future missions by verifying in flight the technologies of both novel focusing imaging optics and CMOS sensors for X-ray observation,and by optimizing the working setups of the instrumental parameters.In addition,LEIA is able to carry out scientific observations to find new transients and to monitor known sources in the soft X-ray band,albeit with limited useful observing time available. | Z.X.Ling X.J.Sun C.Zhang S.L.Sun G.Jin S.N.Zhang X.F.Zhang J.B.Chang F.S.Chen Y.F.Chen Z.W.Cheng W.Fu Y.X.Han H.Li J.F.Li Y.Li Z.D.Li P.R.Liu Y.H.Lv X.H.Ma Y.J.Tang C.B.Wang R.J.Xie Y.L.Xue A.L.Yan Q.Zhang C.Y.Bao H.B.Cai H.Q.Cheng C.Z.Cui Y.F.Dai D.W.Fan H.B.Hu J.W.Hu M.H.Huang Z.Q.Jia C.C.Jin D.Y.Li J.Q.Li H.Y.Liu M.J.Liu Y.Liu H.W.Pan Y.L.Qiu M.Sugizaki H.Sun W.X.Wang Y.L.Wang Q.Y.Wu X.P.Xu Y.F.Xu H.N.Yang X.Yang B.Zhang M.Zhang W.D.Zhang Z.Zhang D.H.Zhao X.Q.Cong B.W.Jiang L.H.Li X.B.Qiu J.N.Sun D.T.Su J.Wang C.Wu Z.Xu X.M.Yang S.K.Zhang Z.Zhang N.Zhang Y.F.Zhu H.Y.Ban X.Z.Bi Z.M.Cai W.Chen X.Chen Y.H.Chen Y.Cui X.L.Duan Z.G Feng Y.Gao J.W.He T.He J.J.Huang F.Li J.S.Li T.J.Li T.T.Li H.Q.Liu L.Liu R.Liu S.Liu N.Meng Q.Shi A.T.Sun Y.M.Wang Y.B.Wang H.C.Wu D.X Xu Y.Q Yang Y.Yang X.S.Yu K.X.Zhang Y.L.Zhang Y.H.Zhang Y.T.Zhang H.Zhou X.C.Zhu J.S.Cheng L.Qin L.Wang Q.L.Wang M.Bai R.L.Gao Z.Ji Y.R.Liu F.L.Ma Y.J.Shi J.Su Y.Y.Tan J.Z.Tong H.T.Xu C.B.Xue G.F.Xue W.Yuan | 2023 | Research in Astronomy and Astrophysics2023，23，9： | 2 |
