本研究以桑枝低聚糖为原料,通过体内实验评价其对糖尿病小鼠降血糖功效。通过高脂饲料结合注射链脲佐菌素建立糖尿病小鼠模型,采用低剂量(2.0.00 mg/(kg·bw))、中剂量(400.00 mg/(kg·bw))、高剂量(800.00 mg/(kg·bw))桑枝低聚糖对模型小鼠灌胃干预。定期测定小鼠体质量、空腹血糖值,40 d后测定小鼠口服糖耐量、胰岛素水平、氧化应激水平、肾脏相关酶、肠道菌群组成的变化,观察小鼠结肠的病理形态,评估桑枝低聚糖对糖尿病小鼠血糖等生化指标的影响,及其对肠道菌群的作用。结果表明,与模型组相较,桑枝低聚糖延缓了糖尿病小鼠的体重下降,对空腹血糖和糖耐量均有一定程度降低。经桑枝低聚糖治疗后,糖尿病小鼠的胰岛素水平显著降低(P2.0.00 mg/(kg·bw))下就能够发挥较好的降血糖功效,作用效果与剂量无明显线性关系。

Finding the electromagnetic （EM） counterpart of binary compact star merger, especially the binary neutron star （BNS） merger, is critically important for gravitational wave （GW） astronomy, cosmology and fundamental physics. On Aug. 17, 2.17, Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart, GRB 170817A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope （HE） onboard Insight-HXMT （Hard X-ray Modulation Telescope） is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart （SSS17a/AT2.17gfo） with very large collection area （M000 cm2. and microsecond time resolution in 0.2.5 MeV. In addition, Insight-HXMT quickly implemented a Target of Opportunity （TOO） observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy （0.2.5 MeV） radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817A. Meanwhile, Insight-HXMT/HE provides one of the most stringent constraints （-10-7 to 104 erg/cm2.s） for both GRB170817A and any other possible precursor or extended emissions in 0.2.5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event.

针对2.18年9月17日发生在广东省佛山市的一次台风龙卷过程,对比分析了EnKF和变分方法同化X波段相控阵雷达得到的风场结构。结果表明,EnKF方法和变分方法在同化了X波段相控阵雷达资料之后,都可以得到龙卷母体风暴的涡旋特征。相比之下,EnKF同化分析的涡旋强度更强,台风龙卷母体风暴及其周边三维风场的结构更加完整,与回波结构匹配更好。变分方法同化得到的流场不够连续,台风龙卷母体风暴的涡旋强度偏弱,弱回波区入流也明显偏弱,并不符合概念模型。而两种方法在没有同化相控阵雷达数据时,都无法产生龙卷母体风暴的流场特征。总体而言,相对于变分方法,EnKF同化系统在同化X波段相控阵雷达数据后可以产生更为合理的涡旋结构,台风龙卷母体风暴及其周边动力场结构更合理,这为以后X波段相控阵雷达的业务应用提供了思路。

目的确定我国献血者、反复接受输血患者HPgV-2.染率,阐明HPgV-2.血液安全的可能影响。方法运用血清学、反转录聚合酶链反应(RT-PCR)等方法分别在1060份健康献血者、1402.HCV、500份HBV、570份反复接受输血者、2.8份血友病患者共3780份血清标本中检测抗HPgV-2.体和HPgV-2.RNA,对获得的HPgV-2.NS3片段和HPgV-2.基因组进行核酸序列测定和分子进化分析。同时检测献血者、反复接受输血者和血友病患者血清丙型肝炎病毒(HCV)和乙型肝炎病毒(HBV)感染情况辅助作为实验结果。结果(1)感染HCV(RNA+/Ab+)的献血者中抗HPgV-2.体阳性率为1.2.%(17/1402.,核酸阳性率为0.36%(5/1402.,而其他几组人群中几乎未检出HPgV-2.毒,这提示HPgV-2.染可能主要与HCV密切相关(χ2.13.78,P=0.004);(2.5株HPgV-2.毒保守区域NS3区同源性达97.11%,与国外分离毒株比较,其同源性为96.53%,未发现明显变异株。结论健康献血者中HPgV-2.感染率很低,HPgV-2.要和HCV共感染,反复接受输血患者和血友病患者没有发现HPgV-2.染,提示HPgV-2.输血传播不常见,可能对血液安全影响不明显。
