Non-alcoholic fatty liver disease (NAFLD) is a condition linked to obesity and is characterised by high amounts of fat in the liver. This can lead to a high rate of mortality, but it can be improved by diet and exercise. It is unclear as to the best form of exercise for the improvement of NAFLD. This randomised control trial aimed to assess the effects of high-intensity interval exercise (HII) versus moderate-intensity exercise on liver fat content in 47 diabetic obese patients with NAFLD over 8 weeks. The results showed that regardless of exercise treatment, both improved measures of NAFLD and there were no differences between the two groups. Interestingly blood sugar control was also improved with both exercise treatments. It was concluded that both exercise regimes improved contributors to NAFLD, with no differences between the two treatments. This study would be useful to health professionals when recommending exercise to diabetic obese patients especially those with NAFLD, giving them the option of HII or MIC to improve their condition.
Abstract
BACKGROUND Some studies assessed the effect of aerobic exercise on diabetic obese patients with hepatic disease, while very limited studies compared high-intensity interval (HII) versus moderate-intensity continuous (MIC) on diabetic obese patients with non-alcoholic fatty liver disease (NAFLD). OBJECTIVES This study was designed to assess the effects of HII versus MIC on intrahepatic triglycerides (IHTG) and visceral lipids in diabetic obese patients with NAFLD. DESIGN Randomized controlled trial. METHODS Forty-seven diabetic obese individuals with NAFLD were enrolled in this study. The individuals were randomly divided into 16 in HII group, 15 in MIC group, and 16 in the controls. HII group received HII exercise, MIC group received 8-week MIC exercise while the control group did not receive any exercise intervention. IHTG and visceral lipids were assessed pre- and post-intervention. RESULTS Baseline and clinical characteristics showed nonsignificant difference among the 3 groups (P > .05). Both HII and MIC groups showed a significant reduction in hepatic fat and visceral lipids (P < .05), while the controls showed nonsignificant difference (P > .05) after completing the study intervention. Postintervention analysis showed nonsignificant changes between the HII and MIC groups (P > .05). CONCLUSIONS Exercise training wither HII or MIC aerobic exercise reduces IHGT and visceral lipids in diabetic obese patients with NAFLD. No differences were observed between the effects of both exercise programs on diabetic obese patients with NAFLD.

Non-alcoholic fatty liver disease (NAFLD) is common in people with obesity and is characterised by high amounts of fat stored in the liver. Diet and exercise are the standard treatments, however recent studies have indicated that the gut microbiota may have an important role. This randomised control trial of 140 patients with NAFLD, aimed to assess the effect of probiotics when added to standard therapy for 3 months. The results showed that although gut microbiota, some aspects of liver function, blood lipids and blood sugars were all improved in individuals on standard therapy, there were additional improvements in those on standard therapy plus probiotics. It was concluded that although standard therapy alone is adequate to improve NAFLD, probiotics plus standard therapy was superior to standard therapy alone and effective in treatment of NAFLD. This study could be used by health professionals to justify the addition of probiotics to standard therapy to further improve NAFLD outcomes.
Abstract
To investigate the effects of probiotics on liver function, glucose and lipids metabolism, and hepatic fatty deposition in patients with non-alcoholic fatty liver disease (NAFLD).Totally 140 NAFLD cases diagnosed in our hospital from March 2017 to March 2019 were randomly divided into the observation group and control group, 70 cases in each. The control group received the diet and exercise therapy, while the observation group received oral probiotics based on the control group, and the intervention in 2 groups lasted for 3 months. The indexes of liver function, glucose and lipids metabolism, NAFLD activity score (NAS), and conditions of fecal flora in 2 groups were compared before and after the treatment.Before the treatment, there were no significant differences on alanine aminotransferase (ALT), aspartate aminotransferase (AST), glutamine transferase (GGT), total bilirubin (TBIL), total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), insulin resistance index (HOMA-IR), NAFLD activity score (NAS), and conditions of fecal flora in 2 groups (P > .05). After the treatment, ALT, AST, GGT, TC, TG, HOMA-IR, NAS, and conditions of fecal flora in the observation group were better than those in the control group, and the observation group was better after treatment than before. All these above differences were statistically significant (P < .05).Probiotics can improve some liver functions, glucose and lipids metabolism, hepatic fatty deposition in patients with NAFLD, which will enhance the therapeutic effects of NAFLD.

Plain language summary
Green tea (GT) consumption has been associated with the prevention and control of type 2 diabetes, cardiovascular and metabolic disease as well as having a positive effect on body weight and composition. However, the polyphenols in GT have been shown to interact with mineral distribution within the body and those minerals have been shown to be deficient in obesity. Studies to measure mineral status in obese subjects supplementing with GT have been inconclusive and this study aimed to measure the serum concentrations of minerals (calcium, copper, iron, zinc, magnesium), body mass index, total antioxidant status (TAS), lipid profile and glucose concentration. 46 obese patients were randomised into 2 groups, one group were supplemented with 279mg of green tea extract (GTE) and 208mg of the polyphenol epigallocatechin-3-gallate (EGCG) and the other group were issued with a placebo for 3 months. The study concluded that GTE improved Zn and Mg, however decreased levels of FE. The results confirmed a positive effect on body mass, lipid profile, glucose and TAS. It was concluded that more studies are required on a larger population over a longer period of time.
Abstract
We report a procedure to purify partially from plasma (approximately 1200 fold) the factor Xa-dependent inhibitor of factor VIIa/tissue factor (i.e., the extrinsic pathway inhibitor or EPI) and describe some of its properties. An assay for EPI was developed based upon inhibition of factor VIIa/tissue factor induced release of activation peptide from tritiated factor IX by a test sample in the presence but not in the absence of factor Xa. Approximately 50% of the total EPI activity in plasma was found in the lipoprotein fraction, which was used as the starting material for purification. Total lipoproteins (isolated by density ultracentrifugation) were delipidated and the urea soluble apoproteins gel filtered on Sephacryl S-200. The inhibitory activity co-eluted with the major protein peak, which primarily contained apoprotein A-I. Inhibitory activity was separated from apoprotein A-I by anion-exchange chromatography on Q-Sepharose and was further resolved from higher and lower molecular weight contaminating proteins by polypreparative disc gel electrophoresis in the presence of 0.1% SDS. Functional inhibitory activity eluted from the polypreparative disc gel in two discrete pools of different molecular weights (approximately 34,000 and approximately 43,000 D). Apoprotein E was identified by immunological techniques as the major protein present in both of these pools. However, incubation with a monospecific polyclonal antibody to human apoprotein E did not decrease EPI activity either in plasma or in the partially purified polypreparative disc gel fractions. A rabbit antiserum was prepared against material from the polypreparative disc gel. The IgG fraction neutralized approximately 95% of the total inhibitory activity present in plasma. Therefore, EPI in the lipoprotein fraction and in the non-lipoprotein fraction of plasma appears to be antigenically similar.
