研究目的:

代谢相关脂肪性肝病既往曾名非酒精性脂肪性肝病其以肝细胞脂肪过量堆积为病理特征的慢性肝病。随着我国经济的快速发展和人民生活水平的不断提高,居民的膳食结构和生活方式也发生了巨大的变化,MAFLD发病率呈现逐年上升且日渐低龄化的趋势,且随着肥胖以及代谢综合征的流行,MAFLD已然成为我国第一大肝病。 其不仅导致肝脏炎症、纤维化和恶性肿瘤的发生,且常合并多种代谢紊乱,引起痛风、2型糖尿病、高血压乃至动脉粥样硬化等重大疾病的发生。从目前国内外的研究来看,生活方式干预仍然是改善MAFLD的一线疗法,且基于运动和均衡饮食以保质保量的生活方式干预被认为是MAFLD管理的基石。有研究表明行为治疗有利于MAFLD患者调整饮食结构和生活习惯,改善患者血脂、体重及肝功能,从而有利于抑制病情进展。 1990年世界卫生组织号召世界人民接受地中海式饮食(mediterranean diet,MD). 地中海饮食的优越性在国外MAFLD患者研究中得到很多的证实但是在国内研究相对较少。其在国内目前主要是应用于糖尿病、痴呆、心血管疾病等方面的研究。Ryan等研究发现,坚持MD可明显改善肝脏脂肪变性、增加胰岛素敏感性。Gepner等评估为期18个月MD对比低脂饮食在MAFLD中的治疗效果,发现治疗6个月时肝内脂肪下降在两组中出现统计学差异,经过治疗18个月与低脂饮食组相比MD组明显降低肝内脂肪含量。且MD是目前欧洲MAFLD指南饮食干预的首选方案。我国传统膳食模式与MD相似,同是以植物性食物为主。鉴于东西方文化差异,对于我国不建议刻板的执行MD,我国居民可以借鉴MD的优点,增加富含膳食纤维的全谷物类、豆类和蔬菜水果等食物的摄入,形成更健康、适合自身的膳食模式。可以建议在MD的基础上,结合我国现实情况使用葵花籽油代替橄榄油,而核桃则是主要的坚果。由于国外研究并未对肝纤维化程度进行评估以及观察周期(18个月)相对较长,我们前期临床试验已经证实隔日禁食能够不通过改变饮食模式下短期内减低体重(且主要是减轻脂肪含量)并改善血脂异常。综合上述本研究主要开展随机对照临床试验,研究改良地中海饮食联合隔日禁食对MAFLD患者体重减轻、血脂控制、肝脏脂肪变性程度的效果、炎症指标、肝纤维化进行前瞻性研究为今后MAFLD的防治提供参考依据。  

Objectives of Study:

Metabolic related fatty liver disease was once known as nonalcoholic fatty liver disease, which is a chronic liver disease characterized by excessive accumulation of hepatocyte fat.With the rapid growth of China's economy and the improvement of people's living standard, the dietary pattern and lifestyle of residents have also changed dramatically. The incidence rate of MAFLD has been increasing year by year and becoming younger. With the prevalence of obesity and metabolic syndrome, MAFLD has become the highest incidence rate of liver disease in China.Not only does it causes liver inflammation, fibrosis and malignant tumors, but also often has multiple metabolic disorders, which can cause gout, type 2 diabetes, hypertension and atherosclerosis.Judging from the research home and broad., lifestyle intervention is considered as the first-choice therapy to improve MAFLD, and lifestyle intervention based on exercise and balanced diet with quality and quantity is considered to be the cornerstone of MAFLD management.Some studies have shown that behavioral therapy is helpful for patients with MAFLD to adjust their dietary structure and living habits, improve their blood lipid, weight and liver function, so as to suppress disease aggravation.In 1990, the World Health Organization called on people all over the world to accept the Mediterranean diet (MD). The advantages of the Mediterranean diet have been confirmed in many studies of MAFLD patients abroad, but there are relatively few studies in China. At present, it is mainly applied in the research of diabetes, dementia, cardiovascular disease and so on.Ryan et al adherence to MD can significantly improve hepatic steatosis and increase insulin sensitivity.Gepner et al. Evaluated the treatment effect of MD with low-fat diet in MAFLD for 18 months and found that there was a statistical difference in the decrease of intrahepatic fat between the two groups after 6 months of treatment. After 18 months of treatment, compared with the low-fat diet group, MD group significantly reduced the content of intrahepatic fat.MD is the first choice of dietary intervention in European MAFLD guidelines.The traditional dietary pattern in China is similar to MD, which is dominated by plant food. In view of the East-West cultural differences, it is not recommended to implement MD rigidly in China. Chinese residents can take advantage of MD to increase the intake of fiber-rich whole grains, beans, vegetables and fruits, so as to develop a healthier, self-appropriate diet pattern.Considering the current situation of our country, it can be suggested to use sunflower oil instead of olive oil on the basis of MD, with walnuts as the main nuts.As the foreign study did not assess the degree of liver fibrosis and the observation period (18 months) is relatively long, our previous clinical trials have confirmed that alternate-day fasting can lose weight (mainly fat content) and improve dyslipidemia in a short time without changing the diet mode.In conclusion, this study mainly carried out randomized controlled clinical trials to study the effect of improved Mediterranean diet combined with alternate day fasting on weight loss, blood lipid control, degree of liver steatosis, inflammatory indexes and liver fibrosis in patients with MAFLD, so as to provide a reference for the prevention and treatment of MAFLD in the future.
