| 1 | Influence of wettability on flow characteristics of water through microtubes and cores显示文摘The flow characteristics of deionized water in hydrophilic and hydrophobic microtubes with diameters of 14.9,5.03 and 2.05 μm are investigated experimentally.The results indicate that the flow characteristics of deionized water in microtubes with diameter of 14.9 μm are in agreement with the classical Hagen-Poiseuille(H-P) equation,but for hydrophilic and hydrophobic microtubes with smaller diameters,the results show significant departure from the prediction of conventional theory,and the discrepancies are influenced by wettability of the microtubes and increase as the Reynolds numbers decrease.Besides,flows of fluid in cores are the macroscopic reflection of flows in countless micron-sized pore throats,the influence of wettability on microscale flow in pore throats will cause the change of seepage characteristic in cores.Therefore,flow experiments of brine through cores with different wettabilities are conducted.The results demonstrate that wettability exerts similar influence on water flows in cores and microtubes. | WANG Fei YUE XiangAn XU ShaoLiang ZHANG LiJuan ZHAO RenBao HOU JiRui | 2009 | Chinese Science Bulletin2009，54，13： | 7 |
| 2 | Induction of embryonic stem cells to hematopoietic cells in vitro显示文摘In order to get hematopoietic cells from embryonic stem (ES) cells and to study development mechanisms of hematopoietic cells, the method of inducing embryonic stem cells to hematopoietic cells was explored by differenciating mouse ES cells and human embryonic cells in three stages. The differentiated cells were identified by flow cytometry, immunohistochemistry and Wright’s staining. The results showed that embryoid bodies (EBs) could form when ES cells were cultured in the medium with 2-mercaptoethanol (2-ME). However, cytokines, such as stem cell factor (SCF), thrombopoietin (TPO), interleukin-3 (IL-3), interleukin-6 (IL-6), erythropoietin (EPO) and granular colony stimulating factor (G-CSF), were not helpful for forming EBs. SCF, TPO and embryonic cell conditional medium were useful for the differentiation of mouse EBs to hematopoietic progenitors. Eighty-six percent of these cells were CD34+ after 6-d culture. Hematopoietic progenitors differentiated to B lymphocytes when they were cocultured | XU Ling QIAO Chunping HUANG Shaoliang LI Shunong WU Xuan | 2000 | Chinese Science Bulletin2000，45，18： | 6 |
| 3 | Experimental investigation on flow characteristics of deionized water in microtubes显示文摘The flow characteristics of deionized water in microtubes with diameters ranging from 2 to 30 μm are investigated. The experimental results show that the flow characteristics in microtubes with diameters of 16 μm and larger ones are in agreement with the classical theory. However, as the diameters are de-creased to 5 and 2 μm, the nonlinear flow characteristics prevail and the results indicate significant departure of flow characteristics from the predictions of the conventional theory, and the smaller the diameters, the larger the departure. As the Reynolds number increases, the degree of nonlinear flow characteristics decrease gradually and the experimental results are approximately equal to the theo-retical expectation. The minimum Reynolds number in this study is only 2.46×10^(-5). | XU ShaoLiang YUE XiangAn HOU JiRui | 2007 | Chinese Science Bulletin2007，52，6： | 6 |
| 4 | In-line X-ray phase-contrast imaging of murine liver microvasculature ex vivo显示文摘Imaging blood vessels is of importance for determining the vascular distribution of organs and tumors.Phase-contrast X-ray imaging can reveal the vessels in much more detail than conventional X-ray absorption method.Visualizing murine liver microvasculature ex vivo with phase-contrast X-ray imaging was performed at Shanghai Synchrotron Radiation Facility.Barium sulfate and physiological saline were used as contrast agents for the blood vessels.Blood vessels of <Φ20μm could be detected by replacing resident blood with physiological saline or barium sulfate.An entire branch of the portal vein (from the main axial portal vein to the ninth generation of branching) could be captured in a single phase-contrast image.It is demonstrated that selective angiography based on phase contrast X-ray imaging,with a physiological material of low Z elements (such as saline) being the contrast agent,is a viable imaging strategy.Further efforts will be focused on using the technique to image tumor angiogenesis. | LI Beilei XU Min WU Weizhong PENG Guanyun ZHANG Xi PENG Yifeng SHI Hongcheng CHEN Shaoliang | 2012 | Nuclear Science and Techniques2012，23，1： | 5 |
| 5 | Comparison of clinical outcomes of Chinese men and women after coronary stenting for coronary artery disease:a multi-center retrospective analysis of 4,334 patients显示文摘The outcome differences between Chinese male and female patients within one-year follow-up after percutaneous coronary intervention(PCI) with stent remain unclear.The present study was aimed to compare clinical outcomes in such two populations.From May 1999 to December 2009,4,334 patients with acute myocardial infarction(MI),unstable angina,stable angina,or silent ischemia,who underwent PCI,were registered at our centers.Among these,3,089 were men and 1,245 were women.We compared these groups with respect to the primary outcomes of MI and secondary outcomes including a composite of major adverse cardiac events(MACE) including cardiac death,MI,target lesion revascularization,target vessel revascularization(TVR),stent thrombosis(ST),definite ST and probable ST at one-year follow-up.Chinese male patients had a higher MACE rate(13%vs.10.7%,P =0.039),mainly led by TVR(9.09%vs.6.98%,P=0.024) at one year,which was significantly different than female patients.Chinese male and female patients showed a significant difference on MACEs.However,there was no significant difference with respect to MI between these groups. | Rajiv Shrestha Jing Xu Dujiang Xie Zhizhong Liu Tian Xu Fei Ye Shiqing Din Xuesong Qian Song Yang Yueqiang Liu Feng Li Aiping Zhang Shaoliang Chen | 2014 | The Journal of Biomedical Research2014，28，5： | 3 |

| 7 | Flow characteristics and reaction properties of carbon dioxide in microtubules and porous media显示文摘Carbon dioxide reacts with porous media while flowing through them enhancing their permeability.Its flow behavior as well as the permeability enhancement effects were studied in synthetic cores,natural cores and microtubes with an inner diameter of 5 μm.The results show that the permeability of H2O-saturated cores(containing carbonate ingredients) was enhanced by increasing the injection volume of a CO2-H2O solution.This enhancement is attributable to carbon dioxide's corrosion,which is justified by SEM scanning.The same phenomenon occurs with a CO2-H2O solution in microtubes,but for a different reason.The gas flow velocity of carbon dioxide in microtubes was approximately 100% faster than that of nitrogen because of the scale and the squeezing effects.Carbon dioxide molecules dissolved in water accelerate the diffusion rate of water molecules within the boundary layer,which in turn diminishes the thickness of the water film and enlarges the effective pore size.This flow behavior facilitates the injection of carbon dioxide into low-permeability reservoirs for oil-displacement and formation energy buildup purposes.This behavior also increases the potential for carbon dioxide channeling or release from the formation. | ZHAO RenBao YUE XiangAn WU YaHong XU ShaoLiang WANG Fei HOU YongLi | 2008 | Chinese Science Bulletin2008，53，21： | 2 |
