研究疾病:

肝硬化(LC)是各种慢性肝病引起的肝损伤的最终病理改变,也是世界范围内发病率和死亡率较高的主要原因,全世界每年约有100万人死于肝硬化,肝硬化是全球第11大最常见的死因,是45-64岁人群的第三大死因。该疾病从无症状期(代偿期肝硬化)演变为有症状期(失代偿期肝硬化),其并发症通常导致患者住院、生活质量受损和高死亡率[1]。随着肝病科学和实践的发展,肝硬化的病程已经从传统意义上认为从代偿期到失代偿期  

Target disease:

Liver cirrhosis ( LC ) is the final pathological change of liver injury caused by various chronic liver diseases. It is also the main cause of high morbidity and mortality worldwide. About 1 million people die of liver cirrhosis every year worldwide. Cirrhosis is the 11th most common cause of death in the world and the third leading cause of death for people aged 45-64. The disease evolves from as

Cohort study 

研究目的:

1. 比较肝硬化代偿期、失代偿期和再代偿期患者临床特征、粪便肠道菌群和粪便代谢产物的特点。 2. 结合患者临床数据、粪便肠道菌群和代谢产物,建立并验证肝硬化失代偿患者短期(3个月)和长期(18个月)预后有较高预测价值的预后模型。  

Objectives of Study:

1. The clinical characteristics, fecal intestinal flora and fecal metabolites of patients with compensated, decompensated and re-compensated cirrhosis were compared. 2. Combined with clinical data, fecal intestinal flora and metabolites, a prognostic model with high predictive value for short-term (3 months) and long-term (18 months) prognosis of patients with decompensated cirrhosis was established and verified.
