"Correspondence between prescription and syndrome" is the foundation of the objectification of traditional Chinese medicine diagnosis and treatment， and the objectification of traditional Chinese medicine diagnosis is the key to the modernization of traditional Chinese medicine. Combining modern theories and technological means to explore objective indicators or biomarkers of "correspondence between prescription and syndrome" can help clarify quantitative indicators of syndromes. There is a characteristic microbial population in the intestine that is related to syndromes and prescription efficacy. Intestinal microbiota plays an important indicative and discriminative role in determining the formation and evolution of disease patterns and is also an important characterization and pathway of the therapeutic effect of prescriptions. Therefore， intestinal microbiota can serve as an important biological indicator for the objectification of "correspondence between prescription and syndrome"， and the research content related to "intestinal microbiota-syndrome" and "intestinal microbiota-prescription" is relatively mature. On this basis， the team proposed a research approach and method of "correspondence among intestinal microbiota， syndrome， and prescription"， exploring the biological mechanism of "correspondence between prescription and syndrome" from the perspective of intestinal microbiota. A complete analysis of the "intestinal microbiota-syndrome-prescription" data content of six traditional Chinese medicine diarrhea syndromes was conducted， and the results of intestinal dominant and characteristic microbiota for different syndromes of diarrhea and corresponding formula interventions were obtained. The correlation of key intestinal microbiota and metabolites with the interaction between different syndromes and formula interventions was studied， and the microbiological mechanism of "treating the same disease with different methods" for diarrhea was explored. The research ideas and results provide the possibility for the establishment and application of the theory of "correspondence among intestinal microbiota， syndrome， and prescription" and also provide a research paradigm for other diseases in traditional Chinese medicine. "Correspondence among intestinal microbiota， syndrome， and prescription" is conducive to revealing the micro-mechanisms of the formation and evolution of traditional Chinese medicine syndromes and the efficacy of prescriptions. It establishes an objective diagnosis and treatment system for traditional Chinese medicine syndromes based on intestinal microbiota， providing new methods and ideas for the objective diagnosis and treatment of traditional Chinese medicine syndromes and promoting the modernization and internationalization of traditional Chinese medicine.

ObjectiveTo explore the method of establishing a disease-syndrome combined model of irritable bowel syndrome （IBS-D） with spleen and kidney yang deficiency in mice. MethodsModel establishment： Twenty mice were randomly divided into a normal group and a model group， with 10 mice in each group. The model group was given 50 mg/（kg·d） of 0℃ ice adenine suspension by gavage for 14 days， plus tail-clamping stimulation and restrained in centrifuge tubes for 7 days， and 10 g/（kg·d） of 0 ℃ ice senna decoction by gavage for 5 days to prepare IBS-D spleen and kidney yang deficiency syndrome model. The normal group was given 0.4 ml of sterile water by gavage once a day for 14 days. Behavioral characteristics， food intake， fecal water content， body weight， and rectal temperature were observed in both groups. Pain threshold， gastric residual rate， intestinal propulsion rate， and the content of short-chain fatty acids （SCFAs）， serotonin （5-HT）， adrenocorticotropic hormone （ACTH）， corticosterone （CORT）， and D-xylose in the serum were detected after modeling. Model validation： Forty mice were randomly divided into a blank group （n=10） and a modeling group （n=30）. After successful modeling using the above method， the modeling group was divided into a model control group， Sishen Pill （四神丸） group， and pinaverium bromide group， with 10 mice in each group. The Sishen Pill group was given 5 g/（kg·d） of Sishen Pill decoction by gavage， and the pinaverium bromide group was given 21.63 mg/（kg·d） of pinaverium bromide solution by gavage， while the blank group and the model control group were given 0.70 ml/d of sterile water by gavage， all for 7 days. The indicators were detected as the same with model establishment. ResultsMice in the model group had poor mental status， lethargy， dull hair and loose feces. Compared with the normal group， the model group exhibited reduced food intake and increased fecal water content ； on the 14th day of modeling， the model group showed a slower body weight gain rate and decreased rectal tempe-rature； after 14 days， the model group had increased small intestinal propulsion rate， and serum SCFAs and 5-HT levels with reduced serum levels of ACTH， CORT， and D-xylose （P＜0.05 or P＜0.01）. Model validation indicated that the Sishen Pill group showed improvements in mental state， activity levels， fur smoothness and curling and gathering symptoms， while these symptoms in the pinaverium bromide group were not significantly improved. Compared to the model control group， the Sishen Pill group and pinaverium bromide group had reduced fecal water content and increased food intake， as well as increased body weight gain and elevated rectal temperature on day 4. On the 7th day of administration， the pinaverium bromide group showed lower rectal temperature than Sishen Pill group， and Sishen Pill group showed decreased serum SCFAs and 5-HT levels with increased ACTH， CORT， and D-xylose levels （P＜0.05 or P＜0.01）， while the pinaverium bromide group exhibited reduced 5-HT and elevated CORT level （P＜0.01）. ConclusionA combination of ice adenine plus ice senna leaf gavage， tail clamping， and centrifuge tube restraint can successfully establish a disease-syndrome combined mouse model of IBS-D with spleen-kidney Yang deficiency.

ObjectiveTo study the changes of microbiota in different intestinal niches in the instance of diarrhea with intestinal dampness-heat syndrome and cold-dampness disturbing spleen syndrome， so as to provide objective evidence for treating diarrhea with different methods from the perspective of intestinal flora. MethodThe 16S rRNA gene high-throughput sequencing data of model mice with diarrhea of the two syndromes and the model mice after prescription intervention were retrieved from National Center for Biotechnology Information （NCBI）， and the intestinal dominant bacteria and microbial functions were compared among groups. Spearman's correlation coefficient among the microorganisms in each group was calculated and the co-occurrence networks of intestinal microbiota were constructed to study the interaction of the microbiota. ResultThe microbiota imbalance in intestinal contents of mice with diarrhea of intestinal dampness-heat syndrome was characterized by the enrichment of Muribaculum and Aerococcus， while the imbalance in intestinal mucosa was manifested by the enrichment of Gram-negative Neisseria， Capnocytophaga， and Prevotella （P<0.05）. However， after the treatment with Gegen Qinliantang， the microbiota in two distinct ecosystems was characterized by the enrichment of Lactobacillus and the abundance of Streptococcus in intestinal mucosa was increased. The microbiota imbalance in intestinal contents of diarrhea with cold-dampness disturbing spleen syndrome was characterized by the enrichment of Lactobacillus （P<0.01） and Clostridium sensu stricto 1， while the intestinal mucosa was dominated by the increase of Candidatus arthromitus and Enterobacter. However， after the treatment with Huoxiang Zhengqi powder， the intestinal contents were characterized by Lactobacillus enrichment， while the intestinal mucosal flora was featured by the enrichment of C. arthromitus， Pseudomonas， and Bacillus. Overall， the contribution of dominant bacteria in intestinal mucosa to the difference was higher than that in intestinal contents， and more dominant bacteria in the intestinal mucosa interacted with other bacteria. ConclusionMicrobiota imbalance is different for diarrhea of different syndromes， and the therapeutic effects of corresponding prescriptions are also different. In addition， the microbiota imbalance has different characteristics between intestinal niches for mice with diarrhea of the same syndrome. Therefore， intestinal flora may be one of the biological bases for exploring the characteristics of "treating the diarrhea with different methods" in Chinese medicine.
