1低社会经济地位与美国成年人早发冠状动脉粥样硬化性心脏病的关系显示文摘低社会经济地位(socioeconomic status,SES)的个体承担着不成比例的冠状动脉粥样硬化性心脏病(coronary heart disease,CHD)负担。在美国低收入地区,CHD仍然是死亡的主要原因。该研究旨在评估美国低SES个体的过量CHD负担,以及传统风险因素和与低SES相关因素影响所占的比例。Hamad R Penko J Kazi DS Coxson P Guzman D Pengxiao C.Wei Mason A Wang EA Goldman L Fiscella K Bibbins-Domingo K 周卫(译) 刘莉(审校) 2020中华高血压杂志2020,28,7:7
2OPTIMIZATION OF A WAVE CANCELLATION MULTIHULL SHIP USING CFD TOOLS显示文摘A simple CFD tool, coupled to a discrete surface representation and a gradient based optimization procedure, is applied to the design of optimal hull forms and optimal arrangement of hulls for a wave cancellation multihull ship. The CFD tool, which is used to estimate the wave drag, is based on the zeroth order slender ship approximation. The hu ll surface is represented by a triangulation, and almost every grid point on the surface can be used as a design variable. A smooth surface is obtained via a si mplified pseudo shell problem. The optimal design process consists of two steps . The optimal center and outer hull forms are determined independently in the fi rst step, where each hull forms are determined independently in the first step, where each hull keeps the same displacement as the original design while the wav e drag is minimized. The optimal outer hull arrangement is determined in the se cond step for the optimal center and outer hull forms obtained in the first step . Results indicate that the new design can achieve a large wave drag reduction i n comparison to the original design configuration.C. Yang, R. L■hner, O.

3Combination antiretroviral studies for patients with primary biliary cirrhosis显示文摘Following the characterization of a human betaretrovirus in patients with primary biliary cirrhosis(PBC),pilot studies using antiretroviral therapy have been conducted as proof of principal to establish a link of virus with disease and with the eventual aim to find better adjunct therapies for patients unresponsive to ursodeoxycholic acid.In the first open label pilot study,the reverse transcriptase inhibitor lamivudine had little demonstrable biochemical or histological effect after 1 year.Whereas,lamivudine in combination with zidovudine was associated with a significant reduction in alkaline phosphatase as well as improvement in necroinflammatory score,cholangitis and ductopenia over a 12 mo period.A double blind,multi-center randomized controlled trial using lamivudine with zidovudine for 6 mo confirmed a significant reduction in alkaline phosphatase,ALT and AST in patients on antiviral therapy.However,none of the patients achieved the stringent endpoint criteria for normalization of alkaline phosphatase.Furthermore,some patients developed biochemical rebound consistent with drug resistance.A major fault of these studies has been the inability to measure the viral load in peripheral blood and therefore,provide a direct correlation between improvement of hepatic biochemistry and reduction in viral load.Nevertheless,viral mutants to lamivudine with zidovudine were later characterized in the NOD.c3c4 mouse model of PBC that has been used to test other antiretroviral regimens to betaretrovirus.The combination of tenofovir and emtricitabine reverse transcriptase inhibitors and the HIV protease inhibitor,lopinavir were found to abrogate cholangitis in the NOD.c3c4 mouse model and the same regimen normalized the liver tests in a PBC patient with HIV and human betaretrovirus infection.This combination antiretroviral therapy has now been used in a double blind randomized controlled crossover study for patients with PBC followed by an open label extension study.Only a third of the PBC patients were able to tolerate the lopinavir but those maintained on tenofovir,emtricitabine and lopinavir experienced sustained and clinically meaningful reduction in hepatic biochemistry.While we await the histological and virological evaluation,it is clear that better tolerated regimens of antiretroviral treatment will be required in future clinical trials.Ellina Lytvyak Aldo J Montano-Loza Andrew L Mason 2016World Journal of Gastroenterology2016,22,1:2
