ABSTRACT

Objective:

To investigate the effect of Huayu Jiedu prescription (HYJDP) on gut microbiota and fecal metabolites in mice with endometriosis.

Method:

Normal female C57BL/6J mice were divided into normal control group (CO), endometriosis group (EM) and Chinese medicine Huayu Jiedu decocotion group (CM). CO and EM groups received normal saline and CM group received HYJDP by intragastric administration. Untargeted metabolomics method was used to detect metabolites in fecal supernatant of mice, and receiver operating characteristic (ROC) analysis was used to screen the differential metabolites, 16S rRNA high-throughput sequencing was used to detect the gut microbiota, and Spearman correlation coefficient was used to represent the degree of correlation between differential metabolites and intestinal flora. Lipopolysaccharides (LPSs) in intestinal wall tissueserum and peritoneal lavage fluid were detected by enzyme-linked immunosorbent assayELISA). The expression of Vimentin and E-cadherin in ectopic lesions was detected by immunohistochemistry.

Result:

HYJDP alleviated the disorders of fecal metabolites and gut microbiota in EMS mice, especially with the recovered levels of homoveratric acid, melilotoside C and physapubescin in fecal supernatant. In the comparison of these three factors between EM group and CO group as well as between EM group and CM group, the variable important in projection (VIP) value was both above 2, and AUC in ROC analysis was both >0.9. As compared with EM group, HYJDP restored the abundance of species such as <italic>Lachnospiraceae_NK4A136_group</italic>, <italic>Lactobacillus</italic> and <italic>Blautia </italic>(<italic>P</italic><0.05). In addition, the level of LPS in peritoneal fluid supernatant of EM group was significantly higher than that of CO group (<italic>P</italic><0.05) and CM group (<italic>P</italic><0.05). The protein expression of vimentin and E-cadherin in endometriosis decreased significantly (<italic>P</italic><0.05).

Conclusion:

HYJDP which can improve the intestinal environment and reduce the level of LPS in mice with endometriosis, is an effective drug for the treatment of endometriosis.
