Abstract
BACKGROUND AND OBJECTIVES To study the effects of a low-carbohydrate and high-fiber diet and education on patients with nonalcoholic fatty liver disease. METHODS AND STUDY DESIGN We randomly divided 44 patients with nonalcoholic fatty liver disease into two groups: low-carbohydrate and high-fiber diet and education (intervention group), and education alone (control group). Liver and kidney function, fasting plasma glucose, insulin resistance index, body composition, and controlled attenuation parameter were detected before and after the intervention. RESULTS After 2 months, the body fat, body weight, abdominal circumference, and visceral fat area, fasting plasma glucose, insulin resistance index, and levels of serum alanine aminotransferase, aspartate transaminase, uric acid, and insulin of the intervention group were significantly lower than before (p<0.05). In the female intervention group, the insulin resistance index and levels of serum alanine aminotransferase, uric acid, triglyceride, fasting plasma glucose, and C-peptide were lower and the level of serum high-density lipoprotein cholesterol was higher than in the female control group (p<0.05). In the male intervention group, the levels of serum alanine aminotransferase, triglyceride, and fasting plasma glucose were lower and the level of serum high-density lipoprotein cholesterol was higher compared with the male control group (p<0.05). CONCLUSIONS A low-carbohydrate and high-fiber diet and education can effectively reduce the body weight and body fat of patients with nonalcoholic fatty liver disease and improve metabolic indicators such as liver enzymes, blood glucose, blood lipid, and uric acid. Our female patients showed significantly better improvement in the indicators than our male patients.

Abstract
To analyze the association between non-alcoholic fatty liver disease (NAFLD) and the presence of diabetic retinopathy (DR) in patients with type 2 diabetes mellitus (T2DM).Total 411 T2DM patients were divided into NAFLD and control groups. NAFLD was diagnosed by ultrasound. Retinopathy was diagnosed by fundus photography. All patients were screened based on medical history, physical examinations, and laboratory measurements.The prevalence of NAFLD and DR in T2DM patients was 60.8% and 40.9%, respectively. The presence of DR was associated with diabetes duration, systolic blood pressure (SBP), glycated hemoglobin (HbA1c), and proteinuria (all P < .001) using univariate and multivariate regression analyses. The prevalence of DR was lower in patients with NAFLD than those without NAFLD (37.2% vs 46.6%, P = .065), and significantly lower in patients with moderate and severe NAFLD (30.2% vs 46.6%, P = .012; 14.3% vs 46.6%, P = .024). The presence of DR in NAFLD patients was associated with diabetes duration (P = .032) in Chi-squared analysis.NAFLD and DR were highly prevalent in T2DM patients. Diabetes duration, SBP, HbA1c, and proteinuria were risk factors for DR in T2DM patients. The presence of DR was lower in T2DM patients with NAFLD, which was mainly due to their shorter diabetes duration.
