Abstract

In order to solve the optimal design problem of metropolitan bus transit network, a network optimization model was proposed, which had considered the urban traffic congestion. Firstly it analyzed the malpractices of the shortest path strategy in large cities and reasons of traffic jam. It studied complex network theory and proposed the bypass strategy based on edge betweenness. Through extending the edge betweenness, it defined effectivity edge betweenness and effectivity path. Then it proposed metropolis transit network optimization model based on edge betweenness and designed its algorithm. Take the street network of Changchun City for example to solve. The results show that with the changes of β, the average trip distance first decreases and then increases. When β = 0, it is shortest. The average travel speed first is basically stable and then increases sharply. When β = 1 the residents average travel time is shortest and the network efficiency is highest. At this time optimization model can rapid decrease the losses of network efficiency caused by traffic congestion. [ABSTRACT FROM AUTHOR]

Abstract

Melatonin is a powerful antioxidant. Decreased melatonin excretion has been reported to be associated with several oxidative stress-related diseases. The urinary metabolite of melatonin, 6-sulfatoxymelatonin (aMT6s), has proved to be a very reliable index of melatonin production. The present study aims to evaluate the level of urinary aMT6s in patients with type 2 diabetes mellitus and diabetic retinopathy. Urine samples were collected from 10 patients with diabetes and no diabetic retinopathy (NDR), 19 patients with nonproliferative diabetic retinopathy (NPDR), 38 patients with proliferative diabetic retinopathy (PDR), and 16 subjects without diabetes mellitus, who served as controls. The level of aMT6s in specimens was assayed by a commercial aMT6s ELISA kit, creatinine levels were also measured for each sample to get urinary aMT6s/creatinine ratio. Creatinine-adjusted urinary aMT6s values were compared among four groups. The urinary aMT6s (mean ± SD) levels were 9.95 ± 2.42, 9.90 ± 2.28, 8.40 ± 1.84 and 5.58 ± 1.33 ng/mg creatinine in the controls and in patients with NDR, NPDR, or PDR, respectively. The urinary aMT6s level of the PDR group was significantly lower than that of the control, NDR and DR groups. No significant difference was found among the control, NDR and DR groups. After adjustment for various factors (age, smoking, cancer, and coronary heart disease) that may influence the aMT6s level, the odds-ratio of urinary aMT6s comparing PDR patients to controls was 0.246 (95% confidence interval = 0.108-0.558, P = 0.001). Therefore, the urinary aMT6s level is significantly decreased in diabetic patients with PDR but not in diabetic patients without PDR, which indicates that decreased urinary aMT6s level may be associated with the pathogenesis of PDR.
