摘要
目的:探讨不同中医证型非酒精性脂肪性肝炎(NASH)患者肠道菌群的差异。方法:选择符合诊断和纳入标准的NASH患者74例,其中湿浊内停证21例、肝郁脾虚证16例、湿热内蕴证17例和痰瘀互结证20例。分别收集各组患者血清生化指标和肝脏硬度与可控衰减参数,采用16S rRNA高通量测序检测各组患者肠道菌群的差异性。结果:各中医证型NASH患者的肝功能指标[天门冬氨酸氨基转移酶(AST)、丙氨酸氨基转移酶(ALT)、γ-谷氨酰基转移酶(GGT)]、血脂[总胆固醇(TC)、甘油三酯(TG)]、肝纤维化指标(透明质酸、层粘连蛋白、Ⅲ型前胶原蛋白和Ⅳ型胶原)、可控衰减参数(CAP)和肝脏硬度测量值(LSM)的比较,差异均有统计学意义(P<0.05),而碱性磷酸酶(ALP)、高密度脂蛋白胆固醇(HDL-C)和低密度脂蛋白胆固醇(LDL-C)的比较,差异均无统计学意义(P>0.05)。α多样性结果显示,与肝郁脾虚证比较,湿浊内停证、湿热内蕴证和痰瘀互结证Ace、Chao1和Shannon指数均明显降低,Simpson指数均明显升高(P<0.05)。与湿热内蕴证比较,湿浊内停证和痰瘀互结证Ace和Chao1指数均明显降低,Simpson指数均明显升高(P<0.05)。各中医证型特征菌属鉴定结果显示,湿浊内停证肠道菌群中Ruminococcus和Dorea菌属的丰度明显增加;肝郁脾虚证肠道菌群中Oscillospira和Akkermansia菌属的丰度明显增加;湿热内蕴证肠道菌群中Heamophilus和Agathobacter菌属的丰度明显增加;痰瘀互结证肠道菌群中Alistipes菌属的丰度明显降低,Streptococcus菌属的丰度明显增加。结论:各中医证型肠道菌群多样性和菌群结构存在差异,可能参与NASH病情和中医证候的发生与发展。
Objective To analysis the difference of gut microbiota in patients with nonalcoholic steatohepatitis(NASH)with different Traditional Chinese Medicine(TCM)syndromes type.Methods Seventy-four patients with NASH met the criteria were selected,including 21 cases of congestion of dampness turbidity,16 cases of liver depression and spleen deficiency,17 cases of accumulation of dampness and heat,and 20 cases of phlegm and blood stasis.Serum biochemical indexes,CAP and LSM of patients in each group were collected,and gut microbiota of NASH patients with different TCM syndromes were also analysis by 16S rRNA high-throughput sequencing.Results There were statistically significant differences in liver function indexes(AST,ALT and GGT),lipids indexes(TG and TC),liver fibrosis indexes(HA,LN,PⅢNP and CⅣ),CAP and LSM of NASH patients with different TCM syndrome types(P<0.05),while there was no statistically significant difference in ALP,HDL-C and LDL-C(P>0.05).The diversity results showed that Ace,Chao1 and Shannon indexes of congestion of dampness turbidity,accumulation of dampness and heat and phlegm and blood stasis were significantly lower than those of liver depression and spleen deficiency syndrome,while Simpson index was significantly higher(P<0.05).Compared with the accumulation of dampness and heat,the Ace and Chao1 indexes of the congestion of dampness turbidity and phlegm and blood stasis were significantly lower,and the Simpson index was significantly higher(P<0.05).The identification results of the characteristic gut microbiota of each TCM syndrome type showed that the abundance of Ruminococcus and Dorea genus in the gut microbiota of the congestion of dampness turbidity groupwas significantly increased.The abundance of Oscillospira and Akkermansia genus in the liver depression and spleen deficiency group was increased significantly.The abundance of Hemophilus and Agathobacter in the accumulation of dampness and heat group was increased significantly.The abundance of Alistipes genus in the phlegm and blood stasis group was significantly reduced,while the abundance of Streptococcus genus was significantly increased.Conclusion There are differences in diversity and structure ofgut microbiota among different TCM syndrome type,which may be involved in the occurrence and development of NASH and TCM syndromes.
