以列车-轨道-桥梁系统动力学理论为基础,选择某城市轻轨工程为研究对象,在有限元软件ANSYS单一平台实现车桥耦合复杂非线性系统的过桥动力学分析,研究不同车速下连续梁桥线形变化(桥墩沉降、梁体下挠/上拱)对轻轨列车运行性能影响规律。结果表明:建立的有限元模型具有求解稳定、建模可视、方便拓展分析等特点;线形相同时,伴随车速增加,轻轨列车运行舒适性、安全性降低;在运营速度段(≤80 km/h),线形变化对舒适性指数无显著影响,桥墩沉降(≤30 mm)、梁体下挠/上拱(≤20 mm)对列车运行安全有显著影响但不起控制作用;在检算速度段(≥100 km/h),桥墩沉降(负值)所致凹陷、梁体上拱对车体竖向加速度有显著影响,线形成为列车运行安全主控因素。

The last three decades have seen a significant improvement and advancement in both the diagnostic and therapeu.ic modalities with improved su.gical techniqu., chemoradio and su.portive therapy in cancer treatment. This has produ.ed a correspondingly increase in the 5-year relative su.vival rate for many cancers and for all races. However, the chemo-radiotherapy which is often gonadotoxic, has a su.stantial impact on qu.lity of life issu.s especially that of reprodu.tion in you.g female patients on accou.t of increasing su.vival rates and delayed childbearing in the western hemisphere. This case based discu.sion paper u.ing two real life case scenarios from ou. department focu.es on the negative impact of cancer treatments on fertility and variou. options available for fertility preservation and / or fertility preservation measu.es. It is conclu.ed that a lot of variables have to be considered when deciding u.on fertility preservation treatments inclu.ing patient＇s age, cancer stage, proposed treatment regime and time before it is initiated, availability of partner sperm and issu.s of individu.l patients. The latter inclu.e su.gical complications, ovarian hyperstimu.lation syndrome, delay in cancer treatment and reintrodu.tion of cancer cells, cost, low su.cess rates and experimental natu.e of these treatments and the disposition of gametes in the event that the patient does not su.vive her cancer. It is very important for physician to advise patients of all these factors so that they can make an informed decision regarding the fertility preservation options and each case is u.iqu. and requ.res a different strategy of fertility preservation.

Objective To develop local termination of pregnancy （TOP） dataset and to identify ＂hotspots＂ for highest activity and gaps in ou. fertility control services. Methods This was a retrospective analysis of 305 women who received TOP u.der section C of the Abortion Act 1967 over a period of 9 consecu.ive months from 1st March throu.h to 31st October 2012. Resu.ts There were 275 （90.2%） British White （BW） and 30 non-BW women. Among 30 non-BW women, 10 （3.3%） were British Asian, 8 （2.6%） were Polish, 6 （2.0%） were British Black or Black, 5 （1.6%） were Chinese and i （0.3%） was White Latvian. The TOP rate was 8.9% in the u.der 18 years old and 27.9% in the over 30 years old. Totally 240 TOPs （78. 7%） occu.red in 〈10 weeks and 276 TOPs （90.5%） occu.red u.der 13 weeks of gestation. Eight-five women who received TOP-service have had one or more previou. termination（s） in the last 3 years. The contraception u.e was low pre-TOP and none of the women were on long-acting reversible contraception （LARCs） pre- TOP, inclu.ing those who had repeat terminations. Conclu.ion There are inequ.lities and gaps in the TOP and related services in Grimsby which mu.t be addressed to redu.e the rate of TOP. This is a major challenge involving mu.tiple agencies. Provision of contraception across all age and ethnic grou.s, improving sex edu.ation, engaging with parents and women to improve their negotiation skills for safer sex, su.porting vu.nerable women, redu.ing risk factors e.g. alcohol and su.stance misu.e and raising aspirations across the region will contribu.e to a redu.tion in termination rate.

Pediatric Investigation 2018年第4期2卷 209-215页

作者： Karin KH Ho Frankie WT Cheng Molin KY Lin shirley Wai Vincent Lee Chi-kong Li Department of Paediatrics Prince of Wales HospitalThe Chinese University of Hong KongHong KongChina Children's Cancer Fou.dation Hong KongChina

Importance: Pediatric palliative care (PPC) has gained great attention in western cou.tries, however data on Hong Kong children receiving PPC are limited. There are gaps in knowledge abou. the PPC needs in local children with cancer. Objective: To assess the cu.rent situ.tion of PPC service of Hong Kong children with cancer. Methods: We performed a 10-year retrospective review in a tertiary pediatric oncology u.it and stu.ied the referral pattern, clinical characteristics and services provided. resu.ts: Totally 117 children were referred to PPC Team which constitu.ed 65% deceased children within the stu.y period. The commonest diagnoses were central nervou. system tu.ou. (32.5%), leu.aemia (25.6%) and neu.oblastoma (9.4%). Ninety-one percent of children were referred after the last relapse or stopping cu.ative treatment. The median time of referral to death was 77 days (interqu.rtile range (IQR): 35, 182)The median nu.ber of hospital admission after referral was 2 (IQR: 1, 5), with a median of 27 days total hospital stay (IQR: 10, 60). The reasons for admission were palliative chemotherapy (16.1%), pain control (12.1%) and platelet transfu.ion (11.2%). For the death episode, the median du.ation of hospital stay was 15 days (IQR: 2, 46). Most patients received oxygen (82.0%), intravenou. flu.d (81.2%) and intravenou. analgesic (52.1%). A total of 111 (94.9%) children died in hospital, 15 had been admitted into intensive care u.it (ICu. bu. only 5 (4.5%) died in ICu. Interpretation: Pain control and platelet transfu.ion were common reasons of readmission. Death in ICu.and at home was u.common in Hong Kong situ.tion.

首先,运用基本力学原理,以三跨相等连续梁为对象,推导了梁体应变改变量与支承差异沉降量之间的解析式;并以某刚性轻轨桥为例,证明了微小支承差异沉降导致的应变改变量是可测的。其次,通过三跨不等连续梁模型试验,采用顶升方法模拟差异沉降,深入分析了梁底应变改变量与顶升量之间的关系,同时验证了FBG新型传感器的优越性能。再次,推导了与试验模型对应的梁底应变改变量与桥墩差异沉降之间的关系式,对两种模式(边墩顶升、中墩顶升)在不同差异沉降下的理论解与试验测试结果进行比较分析,结果表明二者吻合程度较高。最后,对识别基本流程与策略作了简要叙述。

以列车-轨道-桥梁系统动力分析理论为基础,基于商业软件ANSYS和APDL语言,针对某城市轻轨工程,建立考虑简支梁桥线形变化的轻轨列车-轨道-桥梁三维动力非线性分析有限元模型,研究桥墩沉降、梁体下挠/上拱对轻轨列车单双线运行性能的影响。研究结果表明:所建模型具有高效、稳定、可靠、可视等特点;桥梁跨中竖向位移响应在列车交会区约为单线运行时的2倍,轮重减载率与单线过桥相比无显著变化,车体最大加速度和Sperling指数较单线过桥时小幅增加;车速是影响轻轨列车运行安全性最主要的因素,其次是梁体线形变化,而运行方式影响程度最小;伴随车速增加,轻轨列车运行平稳性变差;与车体最大加速度相比,Sperling指数对单双线运行方式的影响有更好区分度。
