Abstract
The dramatic increase in obesity is putting people under increasing pressure. Lipase inhibitors, as a kind of effective anti-obesity drug, have attracted more and more researchers’ attention in recent years because of their advantages of acting on the intestinal tract and having no side effects on the central nervous system. In this study, lipase inhibitor Fu Brick Theophylline (FBT) was screened based on enzyme molecular dynamics, and the inhibition mechanism of lipase inhibitors on obesity was analyzed and discussed at the cellular level and animal model level. We found that FBT had high inhibition effects of lipase with an IC50 of 1.02~0.03 μg/mL. Firstly, the laboratory used 3T3-L1 proadipocytes as models, flow cytometry was used to detect the effects of FBT on the cycle, apoptosis and intracellular ROS activity of proadipocytes. To study the contents of triglyceride, total cholesterol, related metabolites and related gene and protein expression in adipocytes. The results showed that FBT could reduce ROS production and inflammatory factor mRNA expression during cell differentiation. Secondly, by establishing the animal model of high-fat feed ob nutritional obese mice, the morphological observation and gene expression analysis of body weight, fat rate, adipocyte and hepatocyte metabolism of FBT obese mice were further discussed. It was proven that FBT can effectively reduce the degree of fatty liver, prevent liver fibrosis and fat accumulation, and improve the damage of mitochondrial membrane structure. This study provides a theoretical basis for the screening and clinical treatment of lipase inhibitors.

Abstract
Non-alcoholic fatty liver disease (NAFLD) has been described as a hepatic manifestation of the metabolic syndrome. When several studies correlated maternal linoleic acid (LA) intake with the development of obesity, only few links have been made between n-6 fatty acid (FA) and NAFLD. Herein, we investigated the influence of both maternal and weaning high LA intake on lipid metabolism and susceptibility to develop later metabolic diseases in offspring. Pregnant rats were fed a control-diet (2% LA) or a LA-rich diet (12% LA) during gestation and lactation. At weaning, offspring was assigned to one of the two diets, i.e., either maintained on the same maternal diet or fed the other diet for 6 months. Physiological, biochemical parameters and hepatic FA metabolism were analyzed. We demonstrated that the interaction between the maternal and weaning LA intake altered metabolism in offspring and could lead to hepatic steatosis. This phenotype was associated with altered hepatic FA content and lipid metabolism. Interaction between maternal and weaning LA intake led to a specific pattern of n-6 and n-3 oxylipins that could participate to the development of hepatic steatosis in offspring. Our findings highlight the significant interaction between maternal and weaning high LA intake to predispose offspring to later metabolic disease and support the predictive adaptive response hypothesis.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is associated with obesity, insulin resistance, type 2 diabetes and cardiovascular disease and can be considered the hepatic manifestation of the metabolic syndrome. NAFLD represents a spectrum of disease, from the relatively benign simple steatosis to the more serious non-alcoholic steatohepatitis, which can progress to liver cirrhosis, hepatocellular carcinoma and end-stage liver failure, necessitating liver transplantation. Although the increasing prevalence of NAFLD in developed countries has substantial implications for public health, many of the precise mechanisms accounting for the development and progression of NAFLD are unclear. The environment in early life is an important determinant of cardiovascular disease risk in later life and studies suggest this also extends to NAFLD. Here we review data from animal models and human studies which suggest that fetal and early life exposure to maternal under- and overnutrition, excess glucocorticoids and environmental pollutants may confer an increased susceptibility to NAFLD development and progression in offspring and that such effects may be sex-specific. We also consider studies aimed at identifying potential dietary and pharmacological interventions aimed at reducing this risk. We suggest that further human epidemiological studies are needed to ensure that data from animal models are relevant to human health.

Abstract
During pregnancy and/or lactation, maternal nutrition is related to the adequate development of the fetus, newborn and future adult, likely by modifications in fetal programming and epigenetic regulation. Fetal programming is characterized by adaptive responses to specific environmental conditions during early life stages, which may alter gene expression and permanently affect the structure and function of several organs and tissues, thus influencing the susceptibility to metabolic disorders. Regarding lipid metabolism during the first two trimesters of pregnancy, the maternal body accumulates fat, whereas in late pregnancy, the lipolytic activity in the maternal adipose tissue is increased. However, an excess or deficiency of certain fatty acids may lead to adverse consequences to the fetuses and newborns. Fetal exposure to trans fatty acids appears to promote early deleterious effects in the offspring's health, thereby increasing the individual risk for developing metabolic diseases throughout life. Similarly, the maternal intake of saturated fatty acids seems to trigger alterations in the liver and adipose tissue function associated with insulin resistance and diabetes. The polyunsaturated fatty acids (PUFAs), particularly long-chain PUFAs (long-chain PUFA-arachidonic acid, eicosapentaenoic acid and docosahexaenoic acid), play an important and beneficial physiologic role in the offspring who receive this fatty acid during critical periods of development. Therefore, the maternal nutritional condition and fatty acid intake during pregnancy and/or lactation are critical factors that are strongly associated with normal fetal and postnatal development, which influence the modifications in fetal programming and in the individual risk for developing metabolic diseases throughout life.

Abstract
BACKGROUND AND AIM Non-alcoholic steatohepatitis (NASH) is the hepatic manifestation of metabolic syndrome (MS). Monosodium glutamate (MSG)-treated ICR mice is a useful model of MS and NASH, but it shows the different patterns of steatosis from human NASH. Because inbred aged DIAR (ddY, Institute for Animal Reproduction) mice spontaneously show the similar pattern of steatosis as NASH, we analyzed their liver pathology after administering MSG. METHODS MSG-treated DIAR mice (DIAR-MSG) and untreated DIAR mice (DIAR-controls) were sacrificed and assessed histopathologically at 29, 32, 40, 48, and 54 weeks of age. The NASH activity score, body mass index, blood glucose level, and oral glucose tolerance test were also assessed. RESULTS The body mass index and blood glucose levels of DIAR-MSG were significantly higher than controls. The oral glucose tolerance test revealed a type 2 diabetes pattern in DIAR-MSG. The livers of DIAR-MSG mice showed macrovesicular steatosis, lobular inflammation with neutrophils, and ballooning degeneration after 29 weeks. At 54 weeks, mild fibrosis was observed in 5/6 DIAR-MSG and 2/5 DIAR-control mice. In imaging mass spectrometry analysis, cholesterol as well as triglyceride accumulated in the liver of DIAR-MSG mice. Atypical liver nodules were also observed after 32 weeks in DIAR-MSG, some with cellular and structural atypia mimicking human hepatocellular carcinoma. The NASH activity score of DIAR-MSG after 29 weeks was higher than that of control mice, suggesting the development of NASH. CONCLUSIONS DIAR-MSG had NASH-like liver pathology and liver nodules typically associated with MS symptoms. DIAR-MSG provides a valuable animal model to analyze NASH pathogenesis and carcinogenesis.

Abstract
Increased metabolic profiles during pregnancy are associated with an increased risk of maternal and neonatal morbidity and remain a significant medical challenge. To our knowledge, no reports are available indicating the effects of calcium-vitamin D supplementation on metabolic profiles among pregnant women at risk for pre-eclampsia. This study was designed to determine the effects of consumption calcium-vitamin D supplements on metabolic profiles among Iranian pregnant women at risk for pre-eclampsia. This randomized single-blind controlled clinical trial was performed among 49 pregnant women at risk for pre-eclampsia, primigravida, aged 18-35 year old who were carrying singleton pregnancy at their third trimester. Subjects were randomly assigned to consume the placebo (n = 25) or calcium-vitamin D supplements (n = 24) for 9 weeks. Calcium-vitamin D supplements were containing 500 mg carbonate calcium plus 200 IU vitamin D3. Fasting blood samples were taken at baseline and after 9 week intervention to measures of Fasting Plasma Glucose (FPG) and serum lipid profiles. Consumption of calcium-vitamin D supplements resulted in decreased FPG and serum triglycerides levels as compared to the placebo (-9.1 vs. 0.5 mg dL(-1); p = 0.03, -11.7 vs. 49.9 mg dL(-1); p = 0.001, respectively). No significant differences were found comparing calcium-vitamin D supplements and the placebo in terms of their effect on serum total-, HDL-, LDL-cholesterol levels. Within-group differences in the placebo group revealed a significant increase in serum triglycerides levels (+49.9 mg dL(-1), p < 0.0001). In conclusion, consumption of calcium-vitamin D supplements for 9 weeks during pregnancy among pregnant women at risk for pre-eclampsia resulted in decreased FPG and serum triglycerides levels as compared to the placebo group, but could not affect serum total-, HDL-, LDL-cholesterol levels.

Abstract
BACKGROUND Due to enhanced fat storage primarily during the mid-pregnancy period, pregnancy is associated with elevated levels of lipid profiles. To our knowledge, no reports are available indicating the effects of probiotic yoghurt consumption on serum lipid profiles in pregnant women. OBJECTIVE This study was designed to determine the effects of daily consumption of probiotic yoghurt on lipid profiles of Iranian pregnant women. METHODS This randomized single-blinded controlled clinical trial was performed among 70 pregnant women, primigravida, aged 18-30 years old who were carrying singleton pregnancy at their third trimester. Subjects were randomly assigned to consume 200 g/d of conventional (n=33) or the probiotic group (n=37) for 9 weeks. The probiotic yoghurt was a commercially available product prepared with the starter cultures of Streptococcus thermophilus and Lactobacillus bulgaricus, enriched with probiotic culture of two strains of lactobacilli (Lactobacillus acidophilus LA5) and bifidobacteria (Bifidobacterium animalis BB12) with a total of min 1 × 10(7) colony-forming units. The conventional yoghurt contained the starter cultures of S. thermophilus and L. bulgaricus. Fasting blood samples were taken at baseline and after 9-weeks intervention to measure serum lipid profiles. RESULTS Although consumption of probiotic yogurt for 9 weeks had been resulted in a significant reduction in serum total- (-53.7 mg/dL, p=0.001), LDL- (-35.2 mg/dL, p=0.006) and HDL-cholesterol levels (-9.8 mg/dL, p=0.002) as well as serum triglyceride concentrations (-42.8 mg/dL, p=0.029), no significant differences were found comparing probiotic and conventional yogurts in terms of their effect on serum lipid profiles. Within-Group differences in conventional yogurt group revealed a significant reduction in HDL-cholesterol levels (-8.4 mg/dL, p=0.005) and borderline significant reduction in serum total cholesterol concentrations (-21.6 mg/dL, p=0.08). CONCLUSION In conclusion, consumption of probiotic yogurt among pregnant women could not affect serum lipid profiles as compared to the conventional yogurt.
