本试验旨在研究饲料中添加不同水平过氧化氢酶(CAT)对日本沼虾生长性能、抗氧能力、免疫性能和肠道菌群结构的影响。试验共配制6种饲料,分别在基础饲料中添加0(CAT1,对照组)、75(CAT2组)、150(CAT3组)、300(CAT4组)、600(CAT5组)和1200 U/kg(CAT6组)的CAT,饲喂1080只初始体重为(0.10±0.03)g的日本沼虾,每组3个重复,每个重复60只虾。试验期为8周。结果显示:1)各试验组日本沼虾的存活率未受到饲料CAT添加水平的显著影响(P>0.05),但当饲料添加150 U/kg CAT时,日本沼虾的增重率显著高于对照组(P0.05);CAT2、CAT3和CAT4组肝胰腺丙二醛(MDA)含量显著低于其余各组(P0.05)。对日本沼虾肠道菌群进行β多样性分析发现,在门水平上,日本沼虾肠道菌群优势菌门为变形菌门、厚壁菌门和蓝藻菌门,CAT3和CAT4组中变形菌门的相对丰度显著低于对照组(P<0.05),而厚壁菌门相对丰度显著高于对照组(P<0.05);在属水平上,日本沼虾肠道菌群优势菌属为Tyzzerella、气单胞菌属和不动杆菌属,CAT4组中Tyzzerella相对丰度显著高于对照组(P<0.05),而CAT3、CAT4和CAT5组中气单胞菌属相对丰度显著低于对照组(P<0.05)。综上所述,饲料中添加150~300 U/kg的CAT可提高日本沼虾生长性能、抗氧化能力和免疫性能,增加肠道有益菌群的丰度,促进日本沼虾的健康养殖。

Accurate assessment of surface suspended sediment concentration （SSSC） in estuary is essential to address several important issues： erosion, water pollution, human health risks, etc. In this study, an empirical cubic retrieval model was developed for the retrieval of SSSC from Yellow River Estuary. Based on sediments and seawater collected from the Yellow River and southeastern Laizhou Bay, SSSC conditions were reproduced in the laboratory at increasing concentrations within a range common to field observations. Continu- ous spectrum measurements of the various SSSCs ranging from 1 to 5700 mg/1 were carried out using an AvaField-3 spectrometer. The results indicated the good correlation between water SSSC and spectral reflectance （Rrs） was obtained in the spectral range of 726-900 nm. At SSSC greater than 2700 mg/L, the 740-900 nm spectral range was less susceptible to the effects of spectral reflectance saturation and more suitable for retrieval of high sediment concentrations. The best correlations were obtained for the reflectance ratio of 820 nm to 490 nm. Informed by the correlation between Rrs and SSSC, a retrieval model was developed （R2 = 0.992）. The novel cubic model, which used the ratio of a near-infrared （NIR） band （740-900 nm） to a visible band （400-600 nm） as factors, provided robust quantifica- tion of high SSSC water samples. Two high SSSC centers, with an order of 103 mg/1, were found in the inversion results around the abandoned Diaokou River mouth, the present Yellow River mouth to the abandoned Qingshuigou River mouth. There was little sedi- ment exchange between the two high SSSC centers due to the directions of the residual currents and vertical mixing.

目的探讨老年自发性脑出血(SICH)病人早期神经功能恶化(END)的危险因素。方法回顾性分析2019年1月至2022年9月本院收治的100例老年SICH病人的临床资料,根据NIHSS评估结果分为非END组(n=60)与END组(n=40)。比较2组一般资料及实验室指标Hcy、CRP水平,采用多因素Logistic回归分析各指标与END的相关性。结果100例SICH病人中END发生率为40.00%(40/100)。非END组高血压、出血破入脑室占比以及血肿体积、CRP、Hcy水平低于END组(P<0.05)。多因素Logistic回归分析结果显示,高血压、血肿体积、出血破入脑室、CRP、Hcy是老年SICH病人发生END的危险因素(P<0.05)。结论老年SICH病人发生END受较多因素影响,当血肿体积、CRP、Hcy增高时,需注意END的发生。

土壤团聚体组成及稳定性是衡量土壤质量的重要指标,土地利用方式的转变会对其产生不同程度的影响。本研究以黄河三角洲不同退耕年限土地(退耕2年和15年)为对象,以退耕前土地(稻田)和未开垦的自然湿地为对照,分析退耕前后土壤理化性质和土壤团聚体组成及稳定性的变化。结果表明:稻田退耕后土壤(0~40 cm)含水量、总有机碳、溶解性有机碳和全磷整体上呈现随退耕年限延长而增加的趋势,而土壤pH和容重呈下降趋势,但黏粒含量、电导率和全氮含量无明显变化。随退耕年限延长,土壤大团聚体含量整体上呈增加趋势,而小团聚体含量呈减少趋势。表层土壤(0~10 cm)团聚体稳定性随退耕年限延长而增加,退耕15年后,团聚体几何平均直径和平均重量直径较退耕前增加了8.9%和40.4%,而>0.25 mm团聚体质量分数则减少了10.5%;退耕对下层土壤(10~40 cm)团聚体的影响不明显。综上,黄河三角洲退耕还湿对改善土壤结构、提升团聚体稳定性起到积极作用。
