目的:探讨同型半胱氨酸(Hcy)、子宫动脉血流参数与反复妊娠丢失(RPL)患者胰岛素抵抗和妊娠结局的关系。方法:选择2020年6月至2022年10月昆明市妇幼保健院收治的162例RPL患者作为RPL组和同期82例规律产检的健康孕妇作为对照组。按照妊娠结局将RPL患者分为活产组(85例)和流产组(77例)。检测血清Hcy水平,胰岛素抵抗指数(HOMA-IR),超声检查子宫动脉血流参数,包括子宫动脉收缩期峰值/舒张末期流速(S/D)、搏动指数(PI)、血流阻力指数(RI)。Pearson相关性分析Hcy、子宫动脉血流参数与HOMA-IR的相关性。采用多因素Logistic回归分析RPL患者妊娠结局的影响因素。采用受试者工作特征(ROC)曲线分析Hcy、子宫动脉血流参数对RPL患者妊娠结局的预测价值。结果:RPL组血清Hcy水平,S/D、PI、RI以及HOMA-IR均高于对照组(P<0.05)。RPL组血清Hcy,S/D、PI、RI与HOMA-IR均呈正相关(P<0.05)。流产组血清Hcy水平,S/D、PI、RI以及HOMA-IR均高于活产组(P<0.05),多因素Logistic回归分析显示高HOMA-IR、高Hcy、高S/D、高RI、染色体异常是RPL患者流产的危险因素(P<0.05)。ROC曲线分析显示联合Hcy、S/D、RI预测RPL患者流产的曲线下面积(AUC)为0.849,高于单独预测。结论:RPL患者子宫动脉血流参数S/D、RI、PI和血清Hcy水平均增高,高S/D、RI和Hcy与RPL患者胰岛素抵抗以及流产风险增加有关。联合S/D、RI和Hcy可提高RPL流产风险评估效能。

The cDNA library of an ovary from Small Tail Han sheep before estrus was constructed by switching mechanism at 5＇ end of RNA transcript （SMART） approach. This library had a plaque titer of 1 x 109 pfu mL-1 and a 96% recombinant ratio of which the fragment length of inserted average cDNA sequences was 1.0 kb. Based on bioinformatics analysis of the sequences, we obtained 338 expressed sequence tags （ESTs） from 380 cDNA clones which indicated 191 contigs. These contigs consist of 89 unmatched ESTs, 9 homologous known genes in sheep, and 93 homologous sequences in species of mouse, bovine, and human beings, including 19 sequences expressed in the ovary or follicle and 14 unknown sequences. Several candidate genes associated with sheep reproduction trait such as epidermal growth factor （EGF）, estrogen receptor （ESR）, Inhibin, follicle stimulating hormone receptor （FSHR）, prostaglandin （PG）, and transforming growth factor-β （TGF-β） were identified and the homologous were cloned from this library, which will contribute to compile expression profiles and find the major genes of prolificacy of Small Tail Han sheep.

The Shanghai Laser Electron Gamma Source(SLEGS, located in BL03SSID) beamline at the Shanghai Synchrotron Radiation Facility(SSRF) is a Laser Compton Scattering(LCS) gamma source used for the investigation of nuclear structure, which is in extensive demand in fields such as nuclear astrophysics, nuclear cluster structure, polarization physics, and nuclear energy. The beamline is based on the inverse Compton scattering of 10640 nm photons on 3.5 GeV electrons and a gamma source with variable energy by changing the scattering angle from 20° to 160°. γ rays of 0.25-21.1 MeV can be extracted by the scheme consisting of the interaction chamber, coarse collimator, fine collimator, and attenuator. The maximum photon flux for 180° is approximately 10~7 photons/s at the target at 21.7 MeV, with a 3-mm-diameter beam. The beamline was equipped with four types of spectrometers for experiments in( γ,γ'),( γ,n),( γ,p), and( γ,α). At present, Nuclear Resonance Fluorescence(NRF) spectrometry, Flat-Efficiency neutron Detector(FED) spectrometry, neutron Time-Of-Flight(TOF) spectrometry, and Light-Charged Particle(LCP) spectrometry methods have been developed.

The infrared microspectroscopy beamline(BL06B) is a phase Ⅱ beamline project at the Shanghai Synchrotron Radiation Facility(SSRF). The construction and optical alignment of BL06B were completed by the end of 2020. By 2021, it became accessible to users. The synchrotron radiation infrared(SRIR) source included edge radiation(ER) and bending magnet radiation(BMR). The extracted angles in the horizontal and vertical directions were 40 and 20 mrad, respectively. The photon flux, spectral resolution, and focused spot size were measured at the BL06B endstation, and the experimental results were consistent with theoretical calculations. SRIR light has a small divergence angle, high brightness, and a wide wavelength range. As a source of IR microscopy, it can easily focus on a diffraction-limited spatial resolution with a high signal-to-noise ratio(SNR). The BL06B endstation can be applied in a wide range of research fields, including materials, chemistry, biology, geophysics, and pharmacology.
