ObjectiveTo investigate the structural and functional characteristics of gut microbiota in common traditional Chinese medicine （TCM） syndromes of irritable bowel syndrome with diarrhea （IBS-D）. MethodsIBS-D patients who visited the Hospital of Chengdu University of Traditional Chinese Medicine， and healthy participants from the Physical Examination Centre of the same hospital were recruited from 1st January 2020 to 31st March 2021.The IBS-D patients were classified into syndrome of liver constraint and spleen deficiency， and syndrome of spleen deficiency and dampness exuberance； together with the recruited healthy participants， there were liver-constraint group， dampness-exuberance group， and healthy group. General information， including age， gender and body mass index （BMI）， were collected， and Irritable Bowel Syndrome Symptom Severity Scale （IBS-SSS） as well as Irritable Bowel Syndrome Quality of Life Scale （IBS-QOL） scores were additionally collected from IBS-D patients. Fresh fecal samples were also collected and tested by macro-genome sequencing technology for abundance statistical display， PCoA， Anosim， LEfSe bioinformatic analysis of the annotated gut microbiota structure and function. ResultsThere was no statistically significant difference in the general information of the participants in the three groups （P＞0.05）； the difference in the IBS-SSS and IBS-QOL scores between liver-constraint group and dampness-exuberance group were not statistically significant （P＞0.05）. The study included 28 cases each in liver-constraint group， dampness-exuberance group， and healthy group. The number of specific genes to patients in liver-constraint group was 269 135， with 216 156 in dampness-exuberance group and 249 759 in healthy group， accounting of total 1 784 036 in the three groups. There were differences in the relative abundance distribution of the top ten species of gut microbiota among the three groups， with smaller differences at the phylum， class and order levels， and larger differences at the family， genus and species levels. There were differences in the relative abundance of structure and function of the gut microbiota among the three groups. Species PCoA and Anosim analyses at the species level showed significant differences in the composition of the microbiota among the three groups. Further LEfSe analyses showed that patients in liver-constraint group were screened for 14 dominant strains， of which Clostridium sp. CAG 217， Lachnospira pectinoschiza， Anaerotruncus sp. CAG 528， Paeniclostridium sordellii， Eubecterium sp. CAG 76， Bacillus cereus were affected to a greater extent in abundance differences； dampness-exuberance group screened 24 species of dominant bacteria， of which Roseburia inulinivorans， Eubacterium sp. CAG 251， Roseburia hominis， Unclassified Eubacterium rectale， Roseburia intestinalis， and Megamonas funiformis were affected to a greater extent in abundance differences； no dominant functional genes were screened for patients in liver-constraint group， and dampness-exuberance group was screened for flagellum assembly （ko02040）， porphyrin metabolism （ ko00860）， salmonella infection （ko05132）， and benzoic acid degradation （ko00362）. The differentially dominant functional genes in liver-constraint group and dampness-exuberance group may mainly focus on metabolism （including biodegradation and metabolism of exogenous substances， energy metabolism， lipid metabolism， etc.）. ConclusionIBS-D with syndrome of liver constraint and spleen deficiency is characterized by the enrichment of 14 gut microbiota， such as Clostridium sp. CAG 217， while IBS-D with syndrome of spleen deficiency and dampness exuberance is characterized by the enrichment of 24 gut microbiota， such as Roseburia inulinivorans， and 4 functional enrichments， such as flagellum assembly. Clostridium sp. CAG 217 and Roseburia inulinivorans are expected to be biomarkers for IBS-D patients in the two syndromes， respectively.

OBJECTIVE To optimize the extraction technology for the raw drugs of Sanse powder gel paste. METHODS SD rats were divided into blank group， model group， traditional technology group， water extraction group and ethanol extraction group， with 5 rats in each group. Anterior cruciate ligament transection was used to construct knee osteoarthritis model， and the pharmacodynamic effects of different extraction methods on arthritic rats were investigated. Analgesic experiments were conducted using cold and hot pain thresholds and pain mediators calcitonin gene-related peptide （CGRP）， cyclooxygenase-2 （COX-2）， substance P （SP）， and prostaglandin E2 （PGE2） contents as indicators. HE staining was performed on the synovial membrane of rats to observe the degree of synovial cell proliferation， inflammatory infiltration and vascular invasion， and anti-inflammatory experiments were conducted using protein and mRNA expressions of interleukin-1β （IL-1β）， tumor necrosis factor-α （TNF-α） and IL-6 as indicators. The analgesic and anti-inflammatory effects were compared among those groups. In the orthogonal test， ethanol dosage， extraction time and extraction times were used as evaluation factors， and the contents of casticin， strychnine and toxiferine were taken as evaluation indicators； comprehensive score was calculated. The validation experiments were carried out after optimizing the extraction technology of the raw drugs of Sanse powder gel paste. RESULTS Compared with the model group， the cold and heat pain thresholds of drug administration groups （except for the traditional technology group） were all increased significantly （P＜0.05）， while the contents of pain （No.Y2021rc02） mediators CGRP， COX-2， SP and PGE2 were all decreased significantly （P＜0.05）. HE staining showed that inflammatory cell infiltration， fibrosis and collagen deposition were 炎。E-mail：liuzixiu3221@126.com decreased in the administration groups； a small amount of capillary proliferation could be found； the protein and mRNA expressions of inflammatory factors such as IL-1β， IL-6 and TNF-α were decreased significantly in synovial tissue of rats in administration groups （P＜0.05）. Compared with the traditional technology group， most indicators of the ethanol extraction group were significantly reduced （P＜0.05）， and only heat pain threshold and mRNA expression of IL-6 in rats were decreased significantly in the water extraction group （P＜0.05）. The optimal extraction technology of the raw drugs of Sanse powder gel paste included suitable dose of Sanse powder， 8-fold 55% ethanol， heating reflux extraction for 90 minutes， extracting twice. The results of 3 times of verification experiments showed that the average contents of casticin， strychnine and toxiferine were 0.007%， 0.092%， and 0.214%， respectively； RSD were all less than 5%. CONCLUSIONS The optimized extraction technology for the raw drugs of Sanse powder gel paste is stable and feasible， which can improve the efficacy of the preparation.
