Effect of Shaoyaotang on Inflammatory Cytokines and Intestinal Flora in Rats with Dampness-heat Diarrhea
To investigate the effect of Shaoyaotang on diarrhea, inflammation, and intestinal flora in rats with dampness-heat diarrhea and explore the mechanism of therapeutic principle "treating incontinent syndrome with dredging method" of Shaoyaotang.
Method
2
The dampness-heat diarrhea model was induced by high temperature, high humidity, high sugar and fat diet, and pathogenic factors. The rats were divided into normal group, model group (normal saline), Shaoyaotang group (5.62 g·kg
-1
), Rhei Radix et Rhizoma (RRER)-free Shaoyaotang group (5.15 g·kg
-1
), and RRER group (0.01 g·kg
-1
). The rats were treated correspondingly for five days, twice a day in the morning and evening. The diarrhea index was used to evaluate the antidiarrheal effect of each group three hours after the administration in the evening. The levels of tumor necrosis factor (TNF)-
α
, interleukin (IL)-1
β
, IL-2, and IL-6 in the serum were detected by enzyme-linked immunosorbent assay (ELISA) three hours after the last administration. The structure of intestinal flora in feces was characterized by 16sDNA.
Result
2
Compared with the model group, the Shaoyaotang group, the RRER-free Shaoyaotang group, and the RRER group showed reduced diarrhea index (
P
<
0.01), with the onset rates ranking as the Shaoyaotang group
>
the RRER-free Shaoyaotang group
>
the RRER group. Those three groups with drug intervention all showed decreased levels of inflammatory factors (
P
<
0.01), especially the Shaoyaotang group, and no significant difference was observed between the RRER group and the RRER-free Shaoyaotang group. The abundance of pathogenic bacteria and conditioned pathogens (e.g.
Escherichia-Shigella
,
Prevotella
,
Enterorhabdus
, and
Bacteroides
) was reduced and the proliferation of probiotics (such as
Ruminococcus
,
Turicibacter
, and
Lachnospiraceae
) was increased in the groups with drug intervention (
P
<
0.01). For the structure of intestinal flora, the RRER group and the Shaoyaotang group were close to the normal group, and the RRER-free Shaoyaotang group was different from the other three groups (
P
<
0.01).
Conclusion
2
Shaoyaotang can improve the outcome of rats with dampness-heat diarrhea through anti-inflammation and regulation of intestinal flora disorders. RRER in the prescription plays a key role in reducing the abundance of harmful bacteria and promoting the proliferation of probiotics, which is the key of Shaoyaotang in promoting the re-balance of intestinal flora. It also confirms the scientificity of treating dampness-heat diarrhea with RRER following the therapeutic principle "treating incontinent syndrome with dredging method".
