Study on the Characteristics of Gut Microbiota in Chronic Hepatitis B(CHB)Patients with Damp Heat Syndrome and Liver Depression and Spleen Deficiency Syndrome

Objective:This study was designed to explore the characteristics of gut microbiota in CHB patients with two most common traditional Chinese medicine(TCM)Syndromes—damp heat syndrome and liver depression and spleen deficiency syndrome.Methods:According to the diagnostic criteria of Western medicine,TCM and screening exclusion criteria,65 cases of CHB with damp heat syndrome and 28 cases of CHB with liver depression and spleen deficiency syndrome were finally included in the study.All the basic information was gathered and the fresh fecal samples were collected for 16S rDNA sequencing.16S rDNA of gut microbiota was sequenced using Illumina hiseq 2,500 high-throughput sequencing platform.Based on the optimized sequence,Operational Taxonomic Units(OTU)clustering analysis and taxonomic annotation were carried out.Results:The difference in relative abundance of gut microbiota was significant between damp heat syndrome and liver depression and spleen deficiency syndrome in CHB patients.Cyanobacteria was only found in damp heat syndrome.The relative abundance of Erysipelotrichia and Subdoligranulum were higher in liver depression and spleen deficiency syndrome,while the relative abundance of Rhodospirillales,Alphaproteobacteria and Lachnospira were higher in the damp heat syndrome.LDA Effect Size(LEfSe)analysis showed that Lachnospira,Olsenella and Subdoligranulum had significant difference in species among the two TCM syndromes.Conclusion:The different characteristics of gut microbiota in the two TCM syndromes of CHB patients may play an important role in syndrome formation of TCM,which provides a new field of vision for the accurate diagnosis and treatment of TCM.

三子养亲汤加味结肠水疗治疗痰湿内阻型非酒精性脂肪性肝病的临床疗效

目的:探讨三子养亲汤加味结肠水疗治疗痰湿内阻型非酒精性脂肪性肝病(NAFLD)的临床疗效。方法:选取痰湿内阻型NAFLD患者100例,经随机数字表法分为治疗组和对照组,各50例。两组患者均予口服水飞蓟宾胶囊与甘草酸二胺胶囊为基础治疗,治疗组则在基础治疗上加用三子养亲汤加味结肠水疗,对照组则加用生理盐水结肠水疗,疗程均为7 d。记录两组患者治疗前后主要中医证候评分、肝脏酶学指标[丙氨酸氨基转氨酶(ALT),天冬氨酸氨基转氨酶(AST),γ-谷氨酸转肽酶(GGT)],血脂指标[胆固醇(TCH),甘油三酯(TG)],炎症因子指标[白细胞介素-6(IL-6),肿瘤坏死因子-α(TNF-α)],Fibro Scan测量值[肝脏硬度值(LSM),受控衰减参数(CAP)],尿酸及体质量的变化,并观察不良反应,评价患者的用药安全性。结果:与本组治疗前比较,两组患者治疗后中医证候评分,肝脏酶学指标,血脂指标,炎症因子指标,Fibro Scan CAP,尿酸,体质量均明显降低(P<0.05,P<0.01)。治疗后两组在肝脏酶学指标,TCH,IL-6,LSM较对照组未见统计学差异,治疗后治疗组中医证候评分,UA,TNF-α,Fibro Scan CAP较对照组明显降低(P<0.05)。结论:三子养亲汤加味结肠水疗,不仅能明显改善痰湿内阻型NAFLD的临床症状,而且还可显著降低TG,UA,TNF-α,Fibro Scan CAP及体质量,可在短期取得内取得一定的临床疗效。

基于肠道微生态与脾胃升降关系探讨非酒精性脂肪性肝病的组方用药思路

非酒精性脂肪性肝病(NAFLD)是一种代谢应激性肝损伤,已成为我国乃至全世界最常见的慢性肝病之一。因此,NAFLD的发生发展过程及其防治都越来越受到人们的重视,而肠道微生态特别是肠道菌群发生紊乱就是导致NAFLD的重要因素之一。NAFLD中医病证溯源、病因病机与脾胃升降失调相关,NAFLD治疗获益有赖脾胃升降。肠道是中医脾胃实现功能的主要部位,肠道菌群是饮食影响宿主代谢状态的调节因子,符合中医学脾胃升降原理的生物学内涵。脾胃气机升降失常所表现的症状与肠道菌群失调时表现的症状具有一致性,故肠道菌群与中医脾胃升降有着密切联系。该文基于现代肠道微生态系统阐述了从中医脾胃升降关系论治NAFLD的理论基础,并据此提出了NAFLD的组方用药思路,主要包括健脾益气升清、行气和胃降浊、化痰活血消积,突出脾胃升降与肠道微生态协调在NAFLD论治中的主导作用;疏肝理气、宣降肺气、升清降浊、温肾助阳,顾及NAFLD发病协同因素,助力脾胃升降,从肠道微生态靶点考量治疗效应;中药保留灌肠激活大肠传导功能而助力胃气通降、协调脾胃气机升降,结合肠道菌群及其代谢的理论,从16s r DNA基因路径关注中药肠道给药途径干预NAFLD的肠道微生态机制。随着肠道菌群研究领域的深入推进,其与脾胃升降和NAFLD的关系将进一步揭示,既承接了我国从古至今运用脾胃升降理论治疗肝病的悠久历史,也将拓展调节肠道微生态(肠道菌群)治疗NAFLD的新视野。
