| 1 | Characteristics of distribution and transport of petroleum contaminants in fracture-karst water in Zibo Area, Shandong Province, China显示文摘Fracture-karst water is an important water resource for the water supply in North China. Petroleum contamination is one of the most problematic types of the groundwater pollution. The characteristics of distribution and transport of the petroleum contaminants in fracture-karst water are different from those in porous water. The flow velocity of fracture-karst water is much faster than the velocity of porous water on an average. Therefore, contaminant transport in fracture-karst water is an absolute advection-dominated problem. The plume of the petroleum contamination may extend to several kilometers from pollution sources. It was not caused by the oil pool floating on the water table but by the oil components dissolved and scattered in groundwater. The distribution of the petroleum contaminants over space are concentrated in the strong conductive zone on the plane. On the vertical section the highest concentration of the oil contaminants appeared in the strata where the contamination sources were | 朱学愚 刘建立 朱俊杰 陈余道 | 2000 | Science China Earth Sciences2000,43,2: | 12 |
| 2 | Factors Associated with Peripheral Neuropathy in Type 2 Diabetes: Subclinical versus Confirmed Neuropathy显示文摘This study determined the prevalence of diabetic peripheral neuropathy(DPN) and subclinical DPN(s DPN) in patients with type 2 diabetes mellitus(T2DM) using nerve conduction study(NCS) as a diagnostic tool. We also investigated the factors associated with the development of s DPN and compared factors between the sD PN and confirmed DPN(cDPN). This cross-sectional study involved 240 T2DM patients who were successively admitted to the endocrinology wards of Wuhan Union Hospital over the period of January to December 2014. Data on the medical history, physical and laboratory examinations were collected. DPN was diagnosed using NCS. One-way ANOVA with least significant difference(LSD) analysis or chi-square tests was used to compare parameters among DNP-free, s DPN and c DPN patients. Independent factors associated with s DPN were determined using logistic regression. The results showed that 50.8% of the participants had DPN, and among them, 17.1% had sDPN. sDPN showed significant independent associations with age, height, HbA1c, presence of atherosclerosis and diabetic retinopathy. Patients with DPN differed significantly from those without DPN with respect to age, duration of disease(DOD), HbA1c, presence of atherosclerosis, diabetic retinopathy, nephropathy and hypertension. Patients with cDPN, relative to those with sDPN, had significantly longer DOD and higher prevalence of peripheral artery disease(PAD) and coronary artery disease(CAD). Our study suggests that a significant number of T2DM patients are affected by s DPN, and the development of this condition is associated with advanced age, tall stature, poor glycaemic control, presence of diabetic retinopathy and atherosclerosis. On the other hand, patients with cDPN tend to have a longer DOD and are more likely to suffer from PAD and CAD. | Yogendranathsing Unmar Mohammad Ishraq Zafar 高峰 | 2017 | Journal of Huazhong University of Science and Technology(Medical Sciences)2017,37,3: | 8 |

| 5 | 连续谱比斜率法叠前CMP道集Q值估计(英文)显示文摘本文针对地震波在地下介质中传播时产生吸收衰减的特性,在基于广义S变换的叠前Q值反演方法的基础上,提出了一种新的吸收系数计算方法。该算法提出使用设定标准初始子波求取累积Q值,再根据Q值与偏移距关系(QVO)线性关系和Dix公式求取零偏移距层间Q值的方法,代替拾取层位后求取叠前层间Q值的方法。在这种情况下,求取谱比斜率的层位界面可为连续的,故称此方法为连续谱比斜率法。与前人的Q值反演方法相比,本文提出的地震波吸收系数新算法易于计算,极大程度上克服了过去方法频谱比求取的不稳定性。通过数值模拟验证了该算法的可行性,将此算法运用在伊拉克艾哈代布油田的实际地震资料中,结果表明本文提出的Q值提取新方法能有效提高Q值剖面分辨率,能正确反映地层对地震波能量的吸收能力,层间信息更加丰富,空间横向稳定性提高,为后续岩性预测及流体识别提供了可靠依据。 | 吴宗蔚 伍翊嘉 徐明华 郭思 | 2018 | Applied Geophysics2018,15,3: | 4 |

| 7 | Single-allergen Sublingual Immunotherapy versus Multi-allergen Subcutaneous Immunotherapy for Children with Allergic Rhinitis显示文摘It has always been controversial whether a single allergen performs better than multiple allergens in polysensitized patients during the allergen-specific immunotherapy. This study aimed to examine the clinical efficacy of single-allergen sublingual immunotherapy(SLIT) versus multi-allergen subcutaneous immunotherapy(SCIT) and to discover the change of the biomarker IL-4 after 1-year immunotherapy in polysensitized children aged 6–13 years with allergic rhinitis(AR) induced by house dust mites(HDMs). The AR polysensitized children(n=78) were randomly divided into two groups: SLIT group and SCIT group. Patients in the SLIT group sublingually received a single HDM extract and those in the SCIT group were subcutaneously given multiple-allergen extracts(HDM in combination with other clinically relevant allergen extracts). Before and 1 year after the allergen-specific immunotherapy(ASIT), the total nasal symptom scores(TNSS), total medication scores(TMS) and IL-4 levels in peripheral blood mononuclear cells(PBMCs) were compared respectively between the two groups. The results showed that the TNSS were greatly improved, and the TMS and IL-4 levels were significantly decreased after 1-year ASIT in both groups(SLIT group: P<0.001; SCIT group: P<0.001). There were no significant differences in any outcome measures between the two groups(for TNSS: P>0.05; for TMS: P>0.05; for IL-4 levels: P>0.05). It was concluded that the clinical efficacy of single-allergen SLIT is comparable with that of multi-allergen SCIT in 6–13-year-old children with HDM-induced AR. | 王忠喜 石涵 | 2017 | Journal of Huazhong University of Science and Technology(Medical Sciences)2017,37,3: | 3 |
| 8 | Seasonal variations of PM10 -- Trace elements, PAHs and Levoglucosan: Rural sugarcane growing area versus coastal urban area in Southeastern Florida, USA. Part II: Elemental concentrations显示文摘The largest sugarcane-growing area in the United States is in South Florida. An estimated 7 million tons of dry sugarcane leafy biomass is removed from the fields before harvest by burning the leaves off the sugarcane stalks. Preharvest sugarcane leaf foliage burning is a major source of airborne particulate matter (PM), polycyclic aromatic hydrocarbons (PAHs), biogenic trace elements such as K, volatile hydrocarbons and other pollutants. In one harvesting period, approximately 22 million tons of C02, a greenhouse gas, is released, 7 million tons from leaf foliage preharvest burning alone and 15 million tons from burning sugarcane bagasse in the sugar mills for power generation. In this study, PMio was collected from Belle Glade, close to the sugarcane-growing area, and from Delray Beach, an urbanized area along the East Coast of Florida. The PM samples were analyzed for trace elements and close to organic compounds. To elucidate the importance of preharvest sugarcane biomass smoke emissions on air quality, 39 trace elements, 18 PAHs, and levoglucosan were selected to apportion ambient PM constituents. Al, Ca and to a great extend also Mg are the major soil-related trace elements and key markers for fugitive soil dust emissions. Similarly, sea salt aerosol blown from the Atlantic Ocean into Florida added appreciably to PMio trace elements concentration, especially Na and Cl. Approximately half of the sea salt aerosol (PMjo -portion) by mass is removed from the atmosphere during the transport of ocean air from Delray Beach to Belle Glade. Ambient acid displacement reactions caused a substantial portion of the Cl (30%) to be liberated from the sea salt aerosol to the atmosphere during transport as gaseous HC1. The PAH concentrations at Belle Glade were high when the biomass combustion markers levoglucosan and I< also showed the highest concentrations. This indicates that during the sugarcane harvest season, when leaf foliage is burned off just before harvest, most of the ambient PAHs associated with PMio are indeed related to preharvest burning, harvesting machinery emissions, bagasse burning in sugarcane mills, and other related activities that consume biomass and/or fossil fuels for sugarcane harvesting and processing. | Orhan Sevim oglu Wolfgang F.

| 10 | Separation mechanism of chiral compounds in chiral stationary phase liquid chromatography显示文摘In this paper,the concept of reversed-or normal-phase chiral stationary phase liquidchromatography has been put forward according to the polar strength of mobile and stationary phases.The statistical model developed in HPLC has been used to investigate the separation mechanism ofD-and L-enantiomer in chiral stationary phase liquid chromatography.It has been observed thatthe variation of capacity factor of enantiomers with mobile phase composition in both reversed-phaseand normal-phase chiral stationary phase liquid chromatography can be described by the fundamentalelution equation lnk’=a+blnC_b+cC_b.The effect of mobile phase composition on the selec-tivity of enantiomers D and L in normal-phase chiral stationary phase liquid chromatography cam bedescribed by the equation lnα=⊿a+⊿blnC_b,but in reversed-phase chiral stationary phaseliquid chromatography the selectivity is almost independant of the mobile phase composition. | ZOU,Han-Fa ZHANG,Yu-Kui LU,Pei-Chang Dalian Chromatographic R & D Center of China Dalian Institute of Chemical Physics,Academia Sinica,Dalian 116011 | 1991 | Chinese Journal of Chemistry1991,9,3: | 1 |

| 17 | Autograft mediated adoptive immunotherapy of cancer in the context of autologous stem cell transplantation显示文摘The infused stem cell autograft in autologous stem cell transplantation(ASCT)has been viewed mainly as hematologic rescue from the myelosuppressive side effect of conditioning regimens.However,recent reports have shown that the immune effector cells collected at the same time as the stem cells can produce an autologous graft-versus-tumor effect,similar to the graft-versus-tumor effect seen in allogeneic stem cell transplantation without the detrimental effects of graftversus-host disease.In this article,we review the different immune effector cells collected and infused from the stem cell autograft and their association with clinical outcome post-ASCT,suggesting that ASCT can be viewed not only as a therapeutic maneuver to recover bone marrow function after deliver high-dose chemotherapy,but also as an adoptive immunotherapeutic intervention capable of eradicating residual tumor cells in patients with cancer. | Luis F Porrata Svetomir N Markovic | 2010 | World Journal of Clinical Oncology2010,1,1: | 1 |

| 19 | Weakly Nonlinear Rayleigh-Taylor Instability in Incompressible Fluids with Surface Tension显示文摘A weakly nonlinear model is established for incompressible Rayleigh—Taylor instability with surface tension. The temporal evolution of a perturbed interface is explored analytically via the third-order solution. The dependence of the first three harmonics on the surface tension is discussed. The amplitudes of bubble and spike are greatly affected by surface tension. The saturation amplitude of the fundamental mode versus the Atwood number A is investigated with surface tension into consideration. The saturation amplitude decreases with increasing A. Surface tension exhibits a stabilizing phenomenon. It is shown that the asymmetrical development of the perturbed interface occurs much later for large surface tension effect. | 郭宏宇 王立锋 叶文华 吴俊峰 张维岩 | 2017 | Chinese Physics Letters2017,34,4: | 0 |
