| 1 | High prevalence of vitamin A deficiency in Crohn's disease patients according to serum retinol levels and the relative dose-response test显示文摘AIM:To assess the vitamin A status of patients with Crohn's disease(CD) by evaluating serum retinol levels and the relative dose response(RDR) test(liver retinol stores).METHODS:Vitamin A nutritional status was measured by serum retinol obtained by high performance liquid chromatography and the RDR test for evaluation of the hepatic stores.Body composition was performed by densitometry by dual-energy X-ray absorptiometry.Vitamin A dietary intake was assessed from a semiquantitative food frequency questionnaire.RESULTS:This study included 38 CD patients and 33 controls.Low serum retinol concentrations were detected in 29% of CD patients vs 15% in controls(P < 0.005).The RDR test was positive in 37% of CD patients vs 12% in controls,which indicated inadequate hepatic vitamin A stores(P < 0.005).Individuals with hypovitaminosis A had lower BMI and body fat compared with those without this deficiency.There was no association between vitamin A deficiency and its dietary intake,ileal location,presence of disease activity and prior bowel resections.CONCLUSION:Patients with CD have higher prevalence of vitamin A deficiency,as assessed by two independent methods. | Márcia Soares-Mota Tianny A Silva Luanda M Gomes Marco AS Pinto Laura MC Mendon?a Maria Lúcia F Farias Tiago Nunes Andrea Ramalho Cyrla Zaltman | 2015 | World Journal of Gastroenterology2015，21，5： | 4 |
| 2 | 改变进气门相位对进气充量的影响显示文摘活塞与进气门交互运动产生的压力波会沿整个进气管传播,这种压力波能适当增加进入发动机气缸的进气质量。进行了改变进气门相位的试验研究,目的是分析它对进气充量的影响。‘试验在一台1. O L,16气门、每缸?,个进气门的产品发动机上进行。先在气流试验台上进行模拟发动机进气流状况的初步试验,然后再在测功器上进行发动机试验。气流试验台测试结果显示,在300CaA范围内改变进气相位角能使进气质量增加。发动机台架试验的结果是在进气门比原来气门开启相位迟开7. 50CaA的情况下测得的。 | Pereira L V M Pires L B M Pinto A A 李慧萍 | 2005 | 国外内燃机2005，37，6： | 2 |
