目的
2
通过分析慢性胃炎湿证、非湿证患者的舌苔菌群特征,探究舌苔菌群与证候间的相关性,为该病证客观化及生物学研究提供数据支持。
方法
2
选取慢性胃炎患者328例,根据中医辨证标准,将其分为湿证组(153例)与非湿证组(175例),其中湿证组包含寒湿困脾组(70例)和脾胃湿热组(83例),非湿证组包含脾胃虚寒组(98例)和胃阴不足组(77例);健康者50例,设为健康对照组。运用16S rDNA高通量测序技术检测并分析各组舌苔菌群的丰度及多样性,应用Spearman法进行舌苔菌群与证候间的相关性分析。
结果
2
①差异菌属显示:与健康对照组比较,寒湿困脾组有18个菌属丰度具有显著性差异[
P

0.05,线性判别(LDA)
>
0.7],脾胃湿热组也有18个菌属具有显著性差异(
P
<
0.05,LDA
>
0.7),这两组差异菌属中有17个相同菌属,其中7个菌属丰度在健康对照组中显著降低(
P
<
0.05,LDA
>
0.7),10个菌属丰度在健康对照组中显著上升(
P
<
0.05,LDA
>
0.7);与脾胃虚寒组比较,寒湿
困脾组有4个菌属具有显著性差异(
P
<
0.05,LDA
>
0.7);与脾胃湿热组比较,寒湿困脾组在门水平上有1个菌门具有显著性差异(
P
<
0.05,LDA
>
0.7)。②相关性分析显示:脾胃湿热证与7个菌属呈显著相关性,与月形单胞菌属(

R
=0.34,
P

R

P

0.001)、卡氏菌属(
R

P

P

R

P
<
0.001)、卡氏菌属(
R
=0.23,
P
<
0.001)呈显著正相关。
结论
2
慢性胃炎湿证(寒湿困脾证、脾胃湿热证)与非湿证(脾胃虚寒证、胃阴不足证)及健康者的舌苔菌群在门、属水平存在显著差异,且脾胃湿热证、寒湿困脾证与特定菌属呈现相关性,提示舌苔微生物群落特征可作为慢性胃炎湿证的客观生物学标志,为中医湿证客观化研究提供了新的微生物学依据。
Objective
2
To explore the correlation between tongue coating microbiota and traditional Chinese medicine (TCM) syndromes by analyzing the characteristics of tongue coating microbiota in chronic gastritis patients with and without dampness syndromes, thereby providing data support for the objectification and biological research of dampness syndromes.
Methods
2
A total of 328 chronic gastritis patients were enrolled and divided into the dampness syndrome group (
n
=153) and non-dampness syndrome group (
n
=175) according to TCM syndrome differentiation criteria. The dampness syndrome group was further subdivided into the cold-dampness affecting the spleen (CDAS) subgroup (
n
=70) and damp-heat in the spleen-stomach (DHSS) subgroup (
n
=83), while the non-dampness syndrome group included the deficiency-cold of spleen-stomach (DCSS) subgroup (
n
=98) and stomach-yin deficiency (SYD) subgroup (
n
=77). Additionally, 50 healthy volunteers were recr
uited as the healthy control (HC) group. High-throughput 16S rDNA sequencing technology was used to detect and analyze the abundance and diversity of tongue coating microbiota in each group. Spearman correlation analysis was used to investigate the relationship between tongue coating microbiota and TCM syndromes.
Results
2
①Differential bacterial genera analysis: Compared with the HC group, 18 bacterial genera showed significant differences in abundance in the CDAS subgroup (
P
<
0.05, LDA
>
0.7), and also 18 bacterial genera exhibited significant differences in the DHSS subgroup (
P
<
0.05, LDA
>
0.7). Among these differential genera, 17 were shared between the two subgroups. Of these shared genera, 7 showed significantly decreased (
P
<
0.05, LDA
>
0.7) abundance and 10 showed significantly increased (
P
<
0.05, LDA
>
0.7) abundance in the HC group. Compared with the DCSS subgroup, 4 bacterial genera displayed significant differences in the CDAS subgroup (
P
<
0.05, LDA
>
0.7). At the phylum level, 1 phylum showed a significant difference between the CDAS subgroup and the DHSS subgroup (
P
<
0.05, LDA
>
0.7). ②Correlation analysis: DHSS syndrome was significantly correlated with 7 bacterial genera: it was positively correlated with
Selenomonas
(
R
=0.21,
P
<
0.001),
Megasphaera
(
R
=0.34,
P
<
0.001),
Atopobium
(
R
=0.28,
P
<
0.001) , and negatively correlated with
Fusobacterium
(
R
=-0.21,
P
<
0.001),
Catonella
(
R
=-0.24,
P
<
0.001) ,
Gemella
(
R
=-0.29,
P
<
0.001) ,
Haemophilu
s (
R
=-0.28,
P
<
0.001). DCSS syndrome was significantly
correlated with 2 bacterial genera: it was positively correlated with
Peptostreptococcus
(
R
=0.25,
P
<
0.001) ,
Catonella
(
R
=0.23,
P
<
0.001).
Conclusions
2
Significant differences in tongue coating microbiota composition exist at both the phylum and genus levels among chronic gastritis patients with dampness syndromes (CDAS, and DHSS), patients with non-dampness syndromes (DCSS, and SYD) and healthy individuals. Moreover, DHSS syndrome and CDAS syndrome correlate with specific bacterial genera. These findings suggest that the characteristics of the tongue coating microbial community may serve as objective biomarkers for dampness syndromes in chronic gastritis, providing novel microbiological evidence for the objectification research of TCM dampness syndromes.
