Nonalcoholic fatty liver disease(NAFLD)is the most common cause of chronic liver disease and comprises a wide range of clinical symptoms from nonalcoholic fatty liver to nonalcoholic steatohepatitis(NASH),advanced fibrosis,and cirrhosis(1).Obesity is the major risk factor of NAFLD and its main treatment is lifestyle modifications,including weight management,dietary changes and physical activity(2).

In robot-assisted surgery projects,researchers should be able to make fast 3D reconstruction. Usually 2D images acquired with common diagnostic equipments such as UT, CT and MRI are not enough and complete for an accurate 3D reconstruction. There are some interpolation methods for approximating non value voxels which consume large execution time. A novel algorithm is introduced based on generalized regression neural network (GRNN) which can interpolate unknown voxles fast and reliable. The GRNN interpolation is used to produce new 2D images between each two succeeding ultrasonic images. It is shown that the composition of GRNN with image distance transformation can produce higher quality 3D shapes. The results of this method are compared with other interpolation methods practically. It shows this method can decrease overall time consumption on online 3D reconstruction.

BACKGROUND Data available on the association between consumption of various types of vegetables and metabolic syndrome (MetS) remain inconsistent. AIM To investigate the association between the intake of various types of vegetables and MetS among children and adolescents and MetS. METHODS The Tehran Lipid and Glucose Study cohort included 424 children and adolescents initially free of MetS. At the 3.6 year follow-up, 47 new cases of MetS were identified. A 168-item semi-quantitative food-frequency questionnaire was used to collect information about total and various types of vegetables consumed, including allium-, green leafy-, fruity-, root-, stalk-, starchy-, potatoes, and cabbage. MetS was defined according to the Cook et al[32] criteria. RESULTS The median (interquartile range) of total vegetable consumption was 217 (146- 344) g/d. After adjustment for demographic characteristics and dietary intake, higher total-(≥ 350 g/d) and higher allium vegetable consumption (≥ 30 g/d) in the fourth quartile were significantly and inversely associated with risk of MetS compared to the first quartile. Consumption of green leafy vegetables in the third (21.4-38.3 g/d) versus the first quartile (≤ 13.5 g/d) demonstrated a significant inverse association with lower risk of MetS in children and adolescents;associations for other types of vegetables consumed were not significant. CONCLUSION Consumption of vegetables, especially allium and green leafy vegetables, in sufficient amounts may be beneficial in reducing the risk of MetS among children and adolescents.
