Abstract Background Nonalcoholic fatty liver disease (NAFLD) has become one of the most common chronic liver diseases worldwide. Triglyceride (TG) accumulation is central to NAFLD development. People now spend most of their day in the postprandial state, and the measurement of postprandial blood lipid concentration can make up for the lack of simple detection of fasting blood lipids. Postprandial triglyceride (PTG) is commonly used as a surrogate for postprandial blood lipid concentrations, and many studies have shown that PTG is a risk factor for NAFLD. The aim of the present study was to investigate the relationship between PTG concentration during oral fat tolerance testing (OFTT) and NAFLD. Methods A total of 472 Chinese adults, aged 25 to 65 years, were enrolled in the study. All the participants underwent OFTT. The serum concentrations of TG and other lipids were measured, and their relationships with NAFLD were analyzed. Results Of the 472 participants, 155 were diagnosed with NAFLD. The fasting and postprandial TG concentrations of the participants with NAFLD were higher than those of healthy participants (P < 0.05). The TG concentrations of the healthy participants peaked 4 h postprandially, whereas those of the participants with NAFLD peaked 6 h postprandially and reached higher peak values. Postprandial TG concentration was significantly associated with a higher risk of NAFLD. Conclusions High PTG is positively related to a higher risk of NAFLD, and the PTG concentrations of patients with NAFLD are higher than in healthy individuals, with a delayed peak. Therefore, 4-h PTG may represent a potential marker of NAFLD. Trial registration ChiCTR1800019514.

Abstract Background: Non-alcoholic fatty liver disease (NAFLD) has become one of the most common chronic liver diseases worldwide. High postprandial serum lipid concentrations have been reported in patients with metabolic syndrome. Meanwhile, postprandial triglyceride (TG) was found to be a potential replacement when fasting TG is not available. We aimed to investigate the relationship between postprandial TG concentration during oral fat tolerance testing (OFTT) and NAFLD. Methods : A total of 472 Chinese adults, aged 25 to 65 years enrolled in this study. All the participants underwent OFTT. Serum triglyceride and other lipid concentrations were measured, and their relationships with NAFLD were analyzed. Results: Of the 472 participants, 155 were diagnosed with NAFLD. The fasting and postprandial TG concentrations of the participants with NAFLD were higher than those of healthy participants (P<0.05). The TG concentrations of the healthy participants peaked 4 h postprandially, whereas those of the participants with NAFLD peaked 6 h postprandially and had higher peak values. Postprandial triglyceride concentration showed significant association with higher risk of NAFLD.Conclusions: Higher postprandial TG concentration is positively related to higher risk of NAFLD, and postprandial TG concnetrations of NAFLD patients were higher than healthy individuals with a delayed peak time. Hence, 4h postprandial TG maybe a potential indicator for NAFLD.Trial registration number: ChiCTR1800019514

Single-nucleotide polymorphisms (SNPs) of apolipoprotein C3 (APOC3) play important role in lipid metabolism, and dyslipidemia underlies nonalcoholic fatty liver disease (NAFLD). But the correlation of serum lipidomics, APOC3 SNPs, and NAFLD remains limited understood. Enrolling thirty-four biopsy-proven NAFLD patients from Tianjin, Shanghai, Fujian, we investigated their APOC3 genotype and serum lipid profile by DNA sequencing and ultraperformance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS), respectively. Scoring of hepatocyte steatosis, ballooning, lobular inflammation, and liver fibrosis was then performed to reveal the role of lipidomics-affecting APOC3 SNPs in NAFLD-specific pathological alterations. Here, we reported that APOC3 SNPs (rs4225, rs4520, rs5128, rs2070666, and rs2070667) intimately correlated to serum lipidomics in NAFLD patients. A allele instead of G allele at rs2070667, which dominated the SNPs underlying lipidomic alteration, exhibited downregulatory effect on triacylglycerols (TGs: TG 54 : 7, TG 54 : 8, and TG 56 : 9) containing polyunsaturated fatty acid (PUFA). Moreover, subjects with low-level PUFA-containing TGs were predisposed to high-grade lobular inflammation (TG 54 : 7, rho = − 0.454 and P = 0.007 ; TG 54 : 8, rho = − 0.411 and P =0.016; TG 56 : 9, rho = − 0.481 and P = 0.004 ). The significant correlation of APOC3 rs2070667 and inflammation grading [G/G vs. G/A+A/A: 0.00 (0.00 and 1.00) vs. 1.50 (0.75 and 2.00), P = 0.022 ] further confirmed its pathological action on the basis of lipidomics-impacting activity. These findings suggest an inhibitory effect of A allele at APOC3 rs2070667 on serum levels of PUFA-containing TGs, which are associated with high-grade lobular inflammation in NAFLD patients.

Abstract Background Nonalcoholic fatty liver disease (NAFLD) is indicated by liver steatosis without excessive alcohol use or other liver disease. Several studies have reported that metabolic syndromes such as obesity, type 2 diabetes mellitus, and dyslipidemia have a linear correlation associated with NAFLD pathophysiology. One of the characteristics of dyslipidemia in NAFLD is increase in serum triglycerides. This study aimed to develop a model of NAFLD characterized by an increase in serum triglyceride levels and histological profile of liver steatosis by high-fat diet in rats. Methods Twelve Wistar rats were fed with pellets enriched with 60% fat. They were housed individually, and the remaining pellets were weighted every day for intake evaluation. Blood samples were collected at day 0 and at the end of each trial period at days 7, 14, 21, and 28 for the measurement of triglyceride levels. Every animal from each group was also sacrificed for liver histopathological examination. Results This study has established developing the NAFLD animal model by induction of a high-fat diet. The levels of serum triglycerides were increased from baseline 80.41 ± 12.82 to 1152.00 ± 73.62, 493.66 ± 159.98, 556.00 ± 120.79, and 489.00 ± 156.75 mg/dL at days 7, 14, 21, and 28, respectively. Liver histology also showed liver steatosis development, inflammation, and hepatocellular ballooning, which were associated with the NAFLD state. Conclusions High-fat diet in rats induced hypertriglyceridemia along with NAFLD-like liver histopathology.

Gegen Qinlian Decoction (GQD), a classic Chinese herbal formula, has been widely used in Chinese clinic for centuries and is well defined in treating nonalcoholic fatty liver disease (NAFLD). However, the mechanism action of GQD on NAFLD is still rarely evaluated. The present study aims to investigate the effect of GQD on treatment of NAFLD in rats and to further explore the underlying mechanism. The rat NAFLD model established by high-fat-diet feeding was used in the research. Our results exhibited the liver lesions and steatosis was significantly alleviated in NAFLD rats treated with GQD via Oil Red O and H&E staining. Body weight and liver index in GQD groups were reduced significantly ( P < 0.05 ). Moreover, the biochemical analyzer test results showed that GQD significantly decreased blood lipid levels total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and liver injury indicators alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP), while it increased the level of high-density lipoprotein cholesterol (HDL-C) ( P < 0.05 ). The levels of interferon-β (IFN-β), tumor necrosis factor-α (TNF-α), and malondialdehyde (MDA) after the GQD treatment were significantly lower, and then interleukin-2 (IL-2), superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px) levels were lifted significantly ( P < 0.05 ). Further, GQD blocked the expression of NLRP3, ASC, caspase-1 mRNA, and proteins in the liver tissues significantly ( P < 0.05 ). These findings indicated that GQD can ameliorate the hepatic steatosis and injury of NAFLD. Its possible mechanism involves the modulation of inflammatory cytokines and antioxidative stress and the inhibition of NLRP3 signal axis activation. The results support that GQD may be a promising candidate in the treatment of NAFLD.
