研究目的:

肝硬化患者的肠道菌群失调可通过“肠-肝-脑”轴诱发隐匿性肝性脑病,是隐匿性肝性脑病的主要发病机制。我们前期研究发现肝硬化患者肠道菌群失调与隐匿性肝性脑病的发病率密切相关。本项目拟在前期研究基础上,基于肠道菌群代谢组学方法,应用超高效液相色谱-串联质谱法(UPLC-MS/MS)技术,分析隐匿性肝性脑病患者肠道菌群代谢产物,构建隐匿性肝性脑病患者肠道菌群代谢网络,筛选隐匿性肝性脑病的诊断标志物,在临床上辅助诊断隐匿性肝性脑病,为早期诊断隐匿性肝性脑病开辟新的思路和方法。  

Objectives of Study:

Gut microbiota dysregulation in patients with liver cirrhosis can induce minimal hepatic encephalopathy through the "gut-liver-brain" axis, which is the main pathogenesis of minimal hepatic encephalopathy. Our previous study found that gut microbiota dysregulation was closely related to the occurrence of minimal hepatic encephalopathy in patients with liver cirrhosis. Based on the previous research and the gut microbiota metabonomics, application of ultra high performance liquid chromatography-tandem mass spectrometry (UPLC/MS/MS) technology, we analyzed the gut microbiota metabolites, constructed the gut microbiota metabolic network, and screened the diagnostic markers in patients with minimal hepatic encephalopathy, in order to provide new ideas and methods for early diagnosis of minimal hepatic encephalopathy.

药物成份或治疗方案详述:

1.隐匿性肝性脑病的诊断 纳入实验组的乙肝肝硬化患者(60例)在安静环境下独立接受肝性脑病心理测试积分(PHES)量表测试,以诊断纳入研究的乙肝肝硬化患者是否患有隐匿性肝性脑病。PHES测试包括5项子测试:数字连接试验-A(NCT-A)、数字连接试验-B(NCT-B)、数字符号试验(DST)、轨迹描绘试验(LTT)和系列打点试验(SDT),记录完成PHES量表测试所包含5项测试的时间,对照《肝硬化肝性脑病诊疗指南》(2018年版)提供的中国人群匹配年龄和教育程度的健康人群数据进行评分,以在中国人群中验证的PHES<-4分作为诊断隐匿性肝性脑病的阈值。 2.粪便样本采集及处理 收集所有入组患者新鲜粪便,置于无菌粪便采集管,明确标记后10分钟内送到实验室,迅速转移至-80℃低温冰箱冻存。样本在4℃融化,质量控制后使用甲醇提取代谢物,甲醇和粪便的比例为5:1(mg/g),充分混匀后,在10000g,4℃条件下离心10分钟,上清液经过滤膜(孔径0.22μm)过滤后,转移到超高效液相色谱(UPLC)专用玻璃瓶中待检。 3.色谱检测 应用Waters ACQUITY UPLC I-Class超高效液相色谱系统,采用ACQUITY UPLC BEHC 18分析柱进行反向分离。流动相A: 水/甲酸(99.9:0.1,体积/体积),流动相B:乙腈/甲酸(99.9:0.1,体积/体积)。流动相的流速为400μl/min,流动相A和B的比例呈线性变化,洗脱后的样本直接进入质谱检测。 4.质谱检测 应用Waters Q-TOF Premier质谱仪,电离源采用ESI负离子模式,离子源的温度为100℃。中和及干燥气体为氮气,其流速恒定在 450L/h。质谱的扫描范围为m/z 50-1000,数据采集频率0.3s. 采用氩作为碰撞气体,碰撞能量设定在5.0eV. 串联质谱(MS-MS)分析根据目标化合物的稳定性使用不同碰撞能量。飞行时间质谱分析(Q-TOF)的离子飞行模式选用V模式,最大分辨率>10000. 5.统计分析 用MassLynx v4.1软件和Mark-erLynx XS v4.1软件对超高效液相色谱-串联质谱法(UPLC-MS/MS)检测得到的原始数据进行提取、峰判别、峰对齐和归一化等处理。使用SIMCA-P 12.0软件进行主成分分析(PCA)、偏最小二乘法判别分析(PLS-DA)和正交偏最小二乘法判别分析(OPLS-DA)。通过与HMDB和Massbank等数据库比对,确定其差异变量对应的物质,并对差异物质进行受试者工作特征(ROC)曲线分析,筛选出隐匿性肝性脑病的诊断标志物。 6.临床应用 在验证组的乙肝肝硬化患者(40例)中,使用隐匿性肝性脑病诊断标志物筛查是否患有隐匿性肝性脑病,使用ROC曲线评估隐匿性肝性脑病诊断标志物的有效性,计算灵敏度,特异度,阳性预测值、阴性预测值和准确度。 

Description for medicine or protocol of treatment in detail:

1.Diagnosis of minimal hepatic encephalopathy The included 60 patients with hepatitis B-related liver cirrhosis will be independently tested with the psychometric hepatic encephalopathy score (PHES) in a quiet environment to diagnose minimal hepatic encephalopathy. The PHES test includes 5 subtests: number connection test-A (NCT-A), number connection test-B (NCT-B), serial dotting test (SDT), line tracing test (LTT) and digit symbol test (DST). The time to complete the 5 subtests of the PHES will be recorded. Compared with the data of age and education-matched healthy Chinese population provided by the Guidelines for the Diagnosis and Treatment of Hepatic Encephalopathy in Liver Cirrhosis (version 2018), the PHES score < -4 points which has been verified in the Chinese population will be used as the threshold for the diagnosis of minimal hepatic encephalopathy. 2.Fecal sample collection and processing Fresh feces of all included patients will be collected using sterile fecal collection tube and sent to the laboratory within 10 minutes. The samples will be clearly marked and stored at -80℃.The samples will be melted at 4℃, and the metabolites will be extracted with methanol after quality control. The ratio of methanol to feces is 5:1 (mg/g). After being fully mixed, the samples will be centrifuged at 4℃ with 10000g for 10 min. The supernatant will be filtered through a filter membrane (pore size 0.22μm) and transferred to a special glass bottle for ultra high performance liquid chromatography (UPLC) testing. 3.Chromatographic detection Reverse separation will be performed using the Waters ACQUITY UPLC I-Class ultra-high performance liquid chromatography system with the ACQUITY UPLC BEHC 18 analytical column. Mobile phase A: water/formic acid (99.9:0.1, volume/volume), mobile phase B: acetonitrile/formic acid (99.9:0.1, volume/volume). The flow rate of mobile phase is 400μl/min, and the ratio of mobile phase A and B is linearly varied. After elution, the samples will be directly detected by mass spectrometry. 4.Mass spectrometry ESI negative ion mode will be used in the Waters Q-TOF Premier mass spectrometer. The temperature of ion source is 100℃. The neutralization and drying gas is nitrogen, whose flow rate is constant at 450L/h. The scanning range of MS is m/z 50-1000, and the data acquisition frequency is 0.3s. Argon is used as the impact gas and the impact energy is set at 5.0eV. Series mass spectrometry (MS-MS) analysis will be used with different impact energies according to the stability of the target compound. The ion flight mode of Q-TOF is V mode, and the maximum resolution is > 10000. 5.Statistical analysis MassLynx v4.1 software and Mark-erLynx XS v4.1 software will be used to extract, discriminate, align and normize the original data detected by UPLC-MS/MS. Principal component analysis (PCA), partial least squares discriminant analysis (PLS-DA) and orthogonal partial least squares discriminant analysis (OPLS-DA) will be performed using SIMCA-P 12.0 software. By comparing with HMDB and Massbank databases, the substances corresponding to the differential variables will be determined, and the receiver operating characteristic (ROC) curve will be analyzed for the differential metabolites to screen the diagnostic markers of minimal hepatic encephalopathy. 6.Clinical application In 40 patients with hepatitis B-related liver cirrhosis in the validation cohort, diagnostic markers for minimal hepatic encephalopathy will be used to screen minimal hepatic encephalopathy. The ROC curve will be used to evaluate the effectiveness, sensitivity, specificity, positive predictive value, negative predictive value and accuracy of diagnostic markers for minimal hepatic encephalopathy.
