| 4 | Gestational diabetes mellitus: Challenges for different ethnic groups显示文摘Ethnicity is defined as'belonging to a social groupthat has a common national or cultural tradition'.Membership of certain ethnic groups has long been associated with increased risk of gestational diabetes mellitus(GDM).Studies that examined ethnic differences amongst women with GDM were often conducted in western countries where women from various ethnic backgrounds were represented.The prevalence of GDM appears to be particularly high among women from South Asia and South East Asia,compared to Caucasian,African-American and Hispanic communities.For some,but not all ethnic groups,the body mass index is a risk factor for the development of GDM.Even within a particular ethnic group,those who were born in their native countries have a different risk profile for GDM compared to those born in western countries.In terms of treatment,medical nutrition therapy(MNT)plays a key role in the management of GDM and the prescription of MNT should be culturally sensitive.Limited studies have shown that women who live in an English-speaking country but predominantly speak a language other than English,have lower rates of dietary understanding compared with their English speaking counterparts,and this may affect compliance to therapy.Insulin therapy also plays an important role and there appears to be variation as to the progression of women who progress to requiring insulin among different ethnicities.As for peri-natal outcomes,women from Pacific Islander countries have higher rates of macrosomia,while women from Chinese backgrounds had lower adverse pregnancy outcomes.From a maternal outcome point of view,pregnant women from Asia with GDM have a higher incidence of abnormal glucose tolerance test results post-partum and hence a higher risk of future development of type2 diabetes mellitus.On the other hand,women from Hispanic or African-American backgrounds with GDM are more likely to develop hypertension post-partum.This review highlights the fact that management needs to be individualised and the clinician should be mindful of the impact that differences in ethnicity may have on the clinical characteristics and pregnancy outcomes inwomen affected by GDM,particularly those living in Western countries.Understanding these differences is critical in the delivery of optimal antenatal care for women from diverse ethnic backgrounds. | Lili Yuen Vincent W Wong | 2015 | World Journal of Diabetes2015,6,8: | 29 |

| 15 | 平面P波入射下海底衬砌隧道地震响应解析分析显示文摘基于Biot流体饱和多孔介质和理想流体介质波动理论,采用Hankel函数积分变换法(HFITM),在考虑水下饱和土的流固耦合及水–土–结构动力相互作用条件下,给出海底衬砌隧道对平面P波散射问题的解析解。Hankel函数积分变换法能够较好地处理半空间表面边界条件,避免了传统研究中的'大圆弧假定'。在解析解的基础上,计算分析了入射角度、入射频率、海水水深和隧道埋深等因素对场地位移和隧道应力的影响。结果表明:入射角度、入射频率、海水水深和隧道埋深对场地位移和隧道应力影响明显;入射角不同时,场地水平位移和隧道动水压力随着入射角的增加而增加,竖向位移和隧道总应力随着入射角的增加而减小;入射频率不同时,隧道应力随着频率的增加而明显减小;海水水深不同时,水深为10倍隧道半径时的场地位移和隧道应力最大;隧道埋深不同时,场地位移和隧道应力随着埋深的增加而减小。 | 朱赛男 李伟华 Vincent W Lee 赵成刚 | 2020 | 岩土工程学报2020,42,8: | 6 |
| 16 | Scattering and reflection of SH waves around a slope on an elastic wedged space显示文摘The scattering and reflection of SH waves by a slope on an elastic wedged space is investigated. A series solution is obtained by using the wave function expansion method. The slope on a wedged space is divided into two subregions by an artificial, auxiliary circular arc. The wave fields with unknown complex coefficients within each sub-region are derived. Applying Graf addition theorem, the scattered waves in the sub-regions are expressed in a global coordinate system. Fourier transform is adopted to derive a consistent form of standing waves in the inner region using the orthogonality of the cosine functions. The boundary-valued problem is solved by stress and displacement continuity along the artificial, auxiliary arc to obtain the unknown complex coefficients. Parametric studies are next performed to investigate how the topography from the slope on the wedged space will affect the scattering and diffraction, and hence the amplification and de-amplification of the SH waves. Numerical results show that the surface motions on the slope of the wedged space is influenced greatly by the topography. Amplification of the surface motions near the slope vertex is significant. The corresponding phases along the wedged space surfaces are consistent with the direction that the SH waves are propagating. | Liu Qijian Wu Zhiyu Vincent W Lee | 2019 | Earthquake Engineering and Engineering Vibration2019,18,2: | 6 |
