| 1 | Associations between haemodynamics and wall enhancement of intracranial aneurysm显示文摘Background and purpose Previous studies have reported about inflammation processes(IPs)that play important roles in aneurysm formation and rupture,which could be driven by blood flow.IPs can be identified using aneurysmal wall enhancement(AWE)on high-resolution black-blood MRI(BB-MRI)and blood flow haemodynamics can be demonstrated by four-dimensional-flow MRI(4D-flow MRI).Thus,this study investigated the associations between AWE and haemodynamics in unruptured intracranial aneurysms(IA)by combining 4D-flow MRI and high-resolution BB-MRI.Materials and methods Between April 2014 and October 2017,48 patients with 49 unruptured IA who underwent both 4D-flow MRI and high-resolution BB-MRI were retrospectively included in this study.The haemodynamic parameters demonstrated using 4D-flow MRI were compared between different AWE patterns using the Kruskal-Wallis test and ordinal regression.Results The results of Kruskal-Wallis test showed that the average wall shear stress in the IA(WSSavg-IA),maximum through-plane velocity in the adjacent parent artery,inflow jet patterns and the average vorticity in IA(vorticityavg-IA)were significantly associated with the AWE patterns.Ordinal regression analysis identified WSSavg-IA(p=0.002)and vorticityavg-IA(p=0.033)as independent predictors of AWE patterns.Conclusion A low WSS and low average vorticity were independently associated with a high AWE grade for IAs larger than 4 mm.Therefore,WSS and average vorticity could predict AWE and circumferential AWE. | Miaoqi Zhang Fei Peng Xin Tong Xin Feng Yunduo Li Huijun Chen Hao Niu Baorui Zhang Guangrong Song Youxiang Li Peng Liu Aihua Liu Rui Li | 2021 | Stroke & Vascular Neurology2021，6，3： | 7 |
| 2 | Soil Macropore Structure Characterized by X-Ray Computed Tomography Under Different Land Uses in the Qinghai Lake Watershed, Qinghai-Tibet Plateau显示文摘Quantification of soil macropores is important to enhance our understanding of preferential pathways for water, air, and chemical movement in soils. However, the soil architecture of different land uses is not well understood in elusive alpine regions. The objective of this study was to quantify the architecture of soil macropores in a Kobresia meadow, farmland, and sand in the Qinghai Lake watershed of northeastern Qinghai-Tibet Plateau, China using X-ray computed tomography. Nine soil cores at 0–50 cm depth were collected at three sites with three replicates. At each site, the three collected cores were scanned using a GE Hi Speed FX/i medical scanner(General Electric, USA). To analyze soil architecture, the number of macropores, macroporosity, and mean macropore equivalent diameter within the 50 cm soil profile were determined from the X-ray computed tomography. Analysis of variance indicated that land use significantly influenced macroporosity, mean macropore equivalent diameter, and number of macropores. The soils of the Kobresia meadow and farmland had greater macroporosity and developed deeper and longer macropores than that of sand. For the Kobresia meadow, macropores were distributed mainly in the 0–10 cm soil layer, while they were distributed in the 0–20 cm soil layer for the farmland. The large number of macropores observed in the soils of the Kobresia meadow and farmland could be attributed to greater root development. The results of this study provided improved quantitative evaluation of a suite of soil macropore features with significant implications for non-equilibrium flow prediction and chemical transport modeling in soils. | HU Xia LI Zongchao LI Xiaoyan WANG Pei ZHAO Yunduo LIU Lianyou LU Yanli | 2018 | Pedosphere2018，28，3： | 3 |

| 4 | Molar heat capacities of La_2Mo_2O_9 and La_(1.9)Sr_(0.1)Mo_2O_(9-δ)显示文摘The molar heat capacities of La2Mo2O9 and La1.9Sr0.1Mo2O9-δ were obtained using the differential scanning calorimetry (DSC) technique in a temperature range from 298 to 1473 K. The DSC curve of La2Mo2O9 showed an endothermal peak around 834 K corresponding to a first-order monoclinic-cubic phase transition, and the enthalpy change accompanying this phase transition is 5.99 kJ/mol. No evident endothermal peak existed in the DSC curve of La1.9Sr0.1Mo2O9-δ, but a broad thermal anomaly existed in its heat capacity curve at around 832 K. In addition, the heat capacity values of La2Mo2O9 and La1.9Sr0.1Mo2O9-δ began to decrease at 1196 and 1330 K, respectively. The non-transitional heat capacity values of La2Mo2O9 and La1.9Sr0.1Mo2O9-δ were formulated using multiple regression analysis in two temperature ranges. | Baijun Yan Jianhua Liu Yunduo Dai Qifeng Shu Zhihua Ren | 2007 | Journal of University of Science and Technology Beijing2007，14，5： | 0 |
| 5 | Age-Period-Cohort Analysis on Long-Term Mortality Trend of Genitourinary Diseases—China,1987–2021显示文摘Summary What is already known about this topic?There has been a lack of attention to genitourinary diseases for an extended period,resulting in limited research on the mortality trends of genitourinary diseases in China.What is added by this report?This study examines the long-term trend of genitourinary diseases'mortality across Chinese individuals of all genders and in various urban and rural regions.Additionally,it investigates the impact of age-period-cohort effects on this trend.What are the implications for public health practice?It is imperative to address genitourinary diseases,particularly among vulnerable populations such as rural older men.Policymakers should prioritize these individuals by providing necessary policy interventions and healthcare support. | Panliang Zhong Chen Chen Yunduo Liu Xinyue Wei Feipeng Cui Shuai Guo Yaohua Tian | 2023 | China CDC weekly2023，5，51： | 0 |
