Objective To explore the relationship between different diagnostic criteria (ATPIII2002, IDF2005 and CDS2007 criteria) for metabolic syndrome (MS) and non-alcoholic fatty liver disease (NAFLD). Methods A total of 666 elderly males admitted to West China Hospital for routine physical examination were involved in this study in May, 2010. The diagnostic agreement rates of different criteria were compared, along with the relationship between different diagnostic criteria for MS and NALFD. Results The diagnostic agreement of CDS2007 criteria with either IDF2005 or ATPIII2002 criteria was good. However, the agreement of ATPIII2002 with IDF2005 was compromised. The prevalence of NAFLD in MS group was significantly higher than that of non-MS group (Plt;0.01). On the basis of CDS2007 criteria, there was significant correlation between NAFLD and MS (Plt;0.000). Conclusion There is a close relation between NAFLD and all three diagnostic criteria of MS. NAFLD is one of the most important risk factors of MS. The diagnostic agreement of CDS2007 criteria with the other two is good, and there is significant correlation between NAFLD and criteria CDS2007 of MS. CDS2007 is found to be of high accuracy and applicability in the diagnosis of MS in Chinese population including the elderly.
目的 了解成都地区非酒精性脂肪肝（NAFLD）及高尿酸血症（HUA）患病情况及相关因素。 方法 对2010年9月－2011年3月健康体检的36 000名18岁以上受检者，进行病史采集、体格检查、空腹血糖、血脂、肝功能、肾功能、血尿酸检测以及上腹部彩色多普勒超声检查。 结果 高尿酸血症（HUA）的总患病率为18.17%。NAFLD患者HUA患病率为39.41%，明显高于总患病率（P＜0.01）。NAFLD患者的HUA患病率随体质量指数（BMI）的增加呈递增趋势。BMI、舒张压、甘油三酯、胆固醇、丙氨酸转氨酶、门冬氨酸氨转移酶、谷氨酰转肽酶、血肌酐、胱抑素C均随着血尿酸水平的升高而递增；高密度脂蛋白随着血尿酸水平的升高而递减。 结论 NAFLD及HUA关系密切，且二者与代谢紊乱联系紧密。
目的 观察罗格列酮钠对血糖控制未达标的2型糖尿病（T2DM）合并与不合并非酒精性脂肪肝（NAFL）患者的降糖疗效和安全性。 方法 2009年1月－2011年1月60例仅用磺脲类和二甲双胍治疗血糖控制未达标的T2DM患者，按合并和不合并NAFL分为观察组和对照组各30例，两组均在原口服降糖药基础上联合加用国产罗格列酮钠4 mg 1次/d，治疗共3个月，观察治疗前后的血糖、胰岛素、糖化血红蛋白（HbA1c）、体质量指数（BMI）、血脂、肝功、血压水平以及药物不良反应，并比较治疗后的血糖达标率。 结果 两组患者治疗后的空腹血糖（FPG）、餐后2 h血糖（2hPG）、HbA1c、空腹胰岛素、甘油三酯和极低密度脂蛋白胆固醇均较治疗前下降，高密度脂蛋白胆固醇较治疗前升高（P＜0.05），而丙氨酸转氨酶、总胆固醇、低密度脂蛋白胆固醇及血压无明显变化（P＞0.05），但观察组治疗后的FPG和2hPG均较对照组下降更明显（P＜0.01），且血糖达标率为73.3%，显著高于对照组的46.7%（P＜0.05），同时观察组餐后2 h胰岛素（2hINS）水平在治疗前后均明显高于对照组而且治疗后有显著下降（P＜0.01），但对照组治疗后2hINS虽然也有下降但无统计学意义（P＞0.05）。观察组治疗前后BMI无明显变化，但对照组治疗后BMI有明显的升高（P＜0.05）。结论 国产罗格列酮钠片对血糖控制未达标的T2DM合并和不合并NAFL患者均有进一步降低血糖、HbA1c以及改善血脂的作用，但对T2DM合并NAFL的患者的降糖疗效更显著，未见加重肝功能损坏，不良反应小，可作为此类患者联合用药的一种选择。
ObjectiveTo expounded the relationship between phenylalanine, tyrosine and their metabolites and non-alcoholic fatty liver disease (NAFLD). MethodThe literatures related to NAFLD in recent years were reviewed and analyzed. ResultThe levels of phenylalanine, tyrosine and their metabolites had changed significantly in the occurrence and development of NAFLD, and could lead to the progress of NAFLD by affecting the related pathways of lipid metabolism. ConclusionPhenylalanine, tyrosine and their related metabolites are associated with NAFLD, but the specific pathogenesis is still unclear.
Objective To systematically review the effect of intermittent fasting on non-alcoholic fatty liver disease (NAFLD). Methods The PubMed, EMbase, Web of Science, Cochrane Library, CNKI, WanFang Data and CBM databases were electronically searched to collect studies on the effect of intermittent fasting on NAFLD from inception to October 1, 2022. Two researchers independently screened the literature, extracted data and evaluated the risk of bias of the included studies. R software was then used for meta-analysis. Results A total of 7 studies were included. The results of meta-analysis showed that intermittent fasting could reduce liver fibrosis (MD=−0.93, 95%CI 1.67 to 0.19, P<0.05), the levels of glutamic oxaloacetic transaminase (MD=−8.96, 95%CI −11.83 to −6.10, P<0.05), glutamyl transpeptidase (MD=−7.86, 95%CI −12.00 to −3.73, P<0.05), and inflammatory molecules (MD=−2.03, 95%CI −3.69 to −0.36, P<0.05). In addition, it reduced dietary (total energy) intake (MD=−255.99, 95%CI −333.15 to −178.82, P<0.05), body weight (MD=−2.42, 95%CI −3.81 to −1.02, P<0.05), BMI (MD=−0.52, 95%CI −0.92 to −0.13, P<0.05) and fat mass (MD=−2.37, 95%CI −4.17 to −0.57, P<0.05). Conclusion Current research evidence shows that intermittent fasting can improve NAFLD and help patients lose weight. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
