Fitting Degrees of Animal Models of Diarrhea-irritable Bowel Syndrome with Clinical Characteristics of Western Medicine and Traditional Chinese Medicine / 中国实验方剂学杂志

Diarrhea-irritable bowel syndrome （IBS-D） is one of the common functional bowel diseases in clinical practice. Since it pathogenesis is complex and has not been fully elucidated， effective treatment methods remains to be developed for this disease. Establishing the animal models of IBS-D in accordance with the clinical characteristics of traditional Chinese medicine （TCM） and Western medicine helps to reveal the pathogenesis of this disease and improve the treatment plan. The fitting degree of an animal model with clinical characteristics is an indicator to evaluate the effectiveness of the animal model in simulating the disease characteristics of Western medicine and the syndromes of TCM based on the latest diagnostic standards. By reviewing the relevant articles about the animal models of IBS-D， we discovered that rats were the preferred animals for modeling， and the models were mainly induced by single factors， double factors， or the combination of multiple factors. The established animal models mainly present symptoms or signs associated with visceral hypersensitivity or/and gastrointestinal motility abnormalities. The single factor-induced rat models of IBS-D had high fitting degrees with the clinical characteristics of Western medicine but low fitting degrees with the TCM syndromes. The animal models induced by two or more factors had high but varied fitting degrees with the clinical characteristics of Western medicine. In addition， the animal models of IBS-D considering TCM syndromes mainly focuses on the syndrome of liver depression and spleen deficiency， and few models were established for the syndromes of spleen-kidney Yang deficiency， spleen-stomach dampness-heat， spleen deficiency and dampness excess， and cold and heat in complexity. Therefore， it is essential to improve the existing or develop new animal models of IBS-D in the future， so as to provide more tools for deciphering the mechanisms of TCM and Western medicine and developing treatment methods for this disease.

Regulatory effects of couplet medicinals of Atractylodes macrocephala-Aucklandia lappa on gut microbiota and short-chain fatty acid metabolism in the irritable bowel syndrome rat with spleen deficiency and diarrhea / 中国药房

OBJECTIVE To investigate the regulatory effects of couplet medicinals of Atractylodes macrocephala-Aucklandia lappa on gut microbiota and short-chain fatty acids （SCFAs） in the diarrhea-type irritable bowel syndrome （IBS-D） rats with spleen deficiency. METHODS The IBS-D rat model with spleen deficiency was induced by intragastric administration of Senna alexandrina combined with restraint stimulation. The model rats were divided into model group， positive control group （pinaverium bromide 1.5 mg/kg）， A. macrocephala-A. lappa low-dose， medium-dose and high-dose groups （0.7， 1.4， 2.8 g/kg）， with 6 rats in each group. Another 6 healthy rats were taken as the blank control group. The blank control group and the model group were given normal saline intragastrically， and other groups were given relevant drug liquid intragastrically， once a day， for consecutive 14 days. The general characteristics of rats and fecal water content were observed， and intestinal sensitivity [evaluating by abdominal wall withdrawal reflex （AWR） threshold] and the intestinal propulsion rate were determined. The serum levels of 5- hydroxytryptamine（5-HT）and SP were detected， and the pathological changes of colon tissue were observed； the protein expressions of 5-HT-3 receptor（5-HT3R）， 5-HT4R and 5-HT transporter（SERT） in colon tissue of rats were detected. 16S rRNA sequencing was performed for the feces of rats in blank control group， model group and A. macrocephala-A. lappa high-dose group； the contents of acetic acid， propionic acid and butyric acid in the feces of the rats were determined. RESULTS Compared with the model group， the body weight after 7 and 14 days of medication， fecal water content， AWR threshold， and the protein expressions of 5-HT4R and SERT in colon tissue were increased significantly in the A. macrocephala-A. lappa medium-dose and high-dose groups （P＜0.05 or P＜0.01）； serum contents of 5-HT and SP， intestinal propulsion rate （except for A. macrocephala-A. lappa medium-dose group）， the protein expression of 5-HT3R in colon tissue were decreased significantly （P＜0.01）； diarrhea relief， mental state recovery， and partially recovery of the structure of colon tissue were all found； moreover， the diversity and species number of gut microbiota were reduced in A. macrocephala-A. lappa high-dose group and the content of butyric acid in fecal samples was significantly reduced （P＜0.05）. CONCLUSIONS The compatibility of A. macrocephala and A. lappa can improve intestinal motility and sensitivity of IBS-D model rats with spleen deficiency， and alleviate diarrhea. This may be related to improving changes in intestinal microbiota structure， reducing 5-HT expression and butyric acid content， and increasing 5-HT4R and SERT expression.

Discussion on the relationship between irritable bowel syndrome and premature ejaculation from 5-HT and prediction of natural drugs / 国际中医中药杂志

Objective:To explore the relationship between irritable bowel syndrome (IBS) and premature ejaculation (PE) from 5-HT; To predict the natural drugs with therapeutic effect.Methods:Targets related to IBS and PE were screened in the GeneCards, DisGeNET, TTD, OMIM, DrugBank databases. After removing duplicates, the two disease targets were intersected and imported into STRING platform, and the protein interaction network between IBS and PE targets related to 5-HT receptor was obtained. GO enrichment analysis was carried out on the intersected targets by R language, and Coremine Medical platform was used for predicting natural drugs.Results:5-HT1A, 5-HT1B, 5-HT2A, 5-HT2C and 5-HT3A were the common targets related to 5-HT in IBS and PE. GO function enrichment yielded 250 gene function related information, mainly enriched in serotonin receptor signaling pathways, cell response to dopamine, and response to dopamine. The prediction of natural drugs obtained 14 kinds of Chinese materia medica, including Nelumbinis Semen, Nelumbinis Rhizomatis Nodus, Nelumbinis Receptaculum, Nelumbinis Stamen, Nelumbinis Folium, Nelumbinis Plumula, Ginkgo Semen, and Ginkgo Folium.Conclusions:Abnormal 5-HT levels can affect gastrointestinal motility, ejaculation latency, and glans sensitivity. Elevated central 5-HT levels are a common pathogenesis of IBS and PE. The interaction between receptors such as 5-HT1A and 5-HT3A and 5-HT can regulate gastrointestinal motility and secretion activities, intestinal nervous system, and reduce intestinal hypersensitivity; increasing the sensitivity of the 5-HT1A receptor can reduce the ejaculation threshold and promote ejaculation, while increasing the sensitivity of the 5-HT2C receptor can increase the ejaculation threshold.

Mechanisms of acupuncture in the treatment of irritable bowel syndrome with diarrhea based on proteomics / 中国组织工程研究

BACKGROUND:As a common clinical digestive disorder,irritable bowel syndrome becomes an advantageous disease of acupuncture treatment.However,the therapeutic mechanisms remain unclear.The methodological characteristics of omics coincide with the multi-target and multi-level characteristics of acupuncture,providing the possibility of revealing the principle of acupuncture in the treatment of the disease. OBJECTIVE:To investigate the pathogenesis of irritable bowel syndrome with diarrhea(IBS-D)and the effect of acupuncture at the combined points(selected based on etiologies and symptoms)on IBS-D based on proteomics. METHODS:Twelve 3-month-old male Sprague-Dawley rats were randomly divided into three groups:a control group,an IBS-D model group and an acupuncture group.The IBS-D rat models were prepared using the CAS method.After successful modeling,bilateral Zusanli points,bilateral Neiguan points and Guanyuan points were selected for acupuncture treatment in the acupuncture group,with a frequency of 120 times/minute,1 minute of acupuncture every 4 minutes,and 15 minutes of needle retention,at an interval of 1 day every 6 days,for 28 days in total.Rats in the normal control group and the model group were not given any intervention.The pressure threshold of rat abdominal retraction reflex was measured to evaluate the visceral hypersensitivity of rats.Proteomics analysis was performed using the liquid chromatography-tandem mass spectrometry-based platform.MaxQuant software,Perseus software and DAVID,KOBAS,VENNY,STRING online tools were used for the bioinformatics analysis of proteomic data.Visualization analysis was done using Cytoscape 3.7.1 software. RESULTS AND CONCLUSION:There were 47 differentially expressed proteins between the IBS-D model and control groups.Function analysis of differentially expressed proteins revealed that the pathogenic mechanism of IBS-D was associated with abnormal energy metabolism,the imbalance of colon motor function and increased visceral sensitivity.Important proteins related to IBS-D pathogenesis included Atp5a1,Atp5c1,Idh3b,Atp2a3,Pdhb,Ppp1ca and Mapk3.Sixty-one differentially expressed proteins were identified between the acupuncture group and IBS-D model group.Acupuncture at the combined points reversed the up-regulation of nine differentially expressed proteins and the down-regulation of nine differentially expressed proteins.Bioinformatics analysis revealed that acupuncture at the combined points for IBS-D could function via multi-targets and multi-pathways,reverse the damage of energy metabolism caused by IBS-D,and play a role against oxidative stress and inflammation,thereby relieving pain and regulating the imbalance of intestinal function.Important proteins related to acupuncture effects included Atp5a1,Atp5c1,Pdhb,Sars,Uqcrc2,Prdx2,Prdx4,Ppp1ca,Manf and Tmsb4x3.All these findings preliminarily illustrate the potential molecular mechanisms of IBS-D and the effect of acupuncture at the combined points in the treatment of IBS-D at the protein level,which provide a basis for the clinical application of acupuncture at the combined points.

Objective This paper summarizes and evaluates the existing animal models of Post-infectious irritable bowel syndrome(PI-IBS)based on the clinical diagnostic criteria and symptom characteristics of PI-IBS in Chinese and western medicine.The goal of this study is to seek out animal models with a high degree of clinical agreement between Chinese and western medicine,and to provide an accurate animal model for the prevention and treatment of PI-IBS in traditional Chinese medicine.Methods The animal strains,modelling methods,and mechanisms of the existing PI-IBS animal models were summarized based on the clinical diagnostic features and symptomatology of PI-IBS,as well as the degree of match was evaluated and the strengths and weaknesses of the preparation of animal models were analyzed,by reviewing the articles related to PI-IBS animal experiments and the preparation of animal models.Results A thorough analysis discovered that Campylobacter jejuni infection model,Trichinella infection model,and liver depression and spleen deficiency syndrome in models of disease and symptom combination showed a comparatively high level of clinical agreement between Chinese and western medicine.Conclusion The existing PI-IBS models had the high degree of coincidence with western medicine,Chinese medicine four diagnoses and syndrome are generally less embodied and collected in the modeling process.The primary symptoms in Chinese medicine diagnosis are primarily based on the observation of animal apparent behaviors,while the observation of the sub-syndrome manifestations is relatively less,which results in failure of judgment of TCM syndrome types.Therefore,it is still necessary to further standardize the criteria for evaluating symptoms and the techniques for identifying disease-syndrome combination animal models.PI-IBS model with the syndrome-clinical characteristics in Chinese and western medicine has significant application value and prospects in the future.The multifactorial composite method of western medicine pathological injury+Chinese medicine etiological stimulation can establish a PI-IBS model with a higher degree of coincidence,which can provide theoretical support for the study of the pathogenesis of PI-IBS,the difference of syndrome,and the prevention and treatment with integrative Chinese and western medicine.It is crucial to guide the clinical diagnosis and treatment of PI-IBS.

Experience in Treating Diarrhea-predominant Irritable Bowel Syndrome Based on the Theory of Spleen Deficiency Generating Turbidity / 中医杂志

Based on the view of "spleen deficiency generating turbidity"， it is believed that the main pathology of irritable bowel syndrome diarrhea-predominant （IBS-D） is spleen deficiency and turbidity excess， with spleen deficiency as the root and turbidity stagnating intestines as the branch， and the treatment principle of draining turbidity and transporting the center was proposed. In the acute stage， turbidity excess is the main cause， the treatment should unblock the bowels and discharge turbidity， commonly with modified Zhishi Daozhi Decoction （枳实导滞汤）； in the remission stage， spleen deficiency is the main cause， the treatment should boost qi and fortify the spleen， commonly with modified Qiwei Baizhu Powder （七味白术散）. Treating the branch in acute conditions， and treating the root in moderate conditions， so as to help restore the conduction function of the intestines and bowels， the transportation and transformation function of the spleen and stomach， then the water and grains have their own way， clear and turbid each in its own way.

Metagenomics of Fecal Gut Microbiota in Common Traditional Chinese Medicine Syndrome Types of Irritable Bowel Syndrome with Diarrhea：A Cross-sectional Study / 中医杂志

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.

Mechanism of Tongxie yaofang reducing colon hypermotility in IBS-D rats by regulating gut microbiota-ENS-MM crosstalk / 中国药房

OBJECTIVE To study the effects of Tongxie yaofang reducing colon hypermotility in irritable bowel syndrome with diarrhea （IBS-D） rats by regulating gut microbiota-enteric nervous system （ENS）-muscularis macrophages （MM） crosstalk. METHODS Forty newborn male SD rats were randomly divided into control group， model group， TCM group [Tongxie yaofang 2.68 g/（kg·d）， calculated by raw material]， and positive control group [Live combined bifidobacterium and lactobacillus tablets 0.27 g/（kg·d）]， with 10 rats in each group. Except for the control group， the IBS-D model of liver stagnation and spleen deficiency syndrome was induced in the other 3 groups with the method of mother-child separation+chronic restraint+Folium Sennae- induced diarrhea. After modeling， the administration groups were given relevant drug liquid intragastrically， once a day， for consecutive 2 weeks. At the end of modeling and after administration， the fecal properties （the incidence and the rate of loose stools）， colonic motility （colon emptying time）， and visceral sensitivity [abdominal withdrawal reflex （AWR） scores under different pressures] of rats were observed in each group. The concentration of lipopolysaccharide （LPS） in serum was detected after medication， and the expressions and distribution of bone morphogenetic protein 2 （BMP2）， colony stimulating factor 1 （CSF1） and Toll-like receptor 4 （TLR4） in colon tissue were detected； the diversity， species composition and differences of gut microbiota were also determined. RESULTS At the end of modeling， compared with the control group， all rats of the other three groups suffered from loose stools （100%）， the rate of loose stools and AWR scores at different pressures increased significantly， and colon emptying time was shortened significantly （P＜0.01 or P＜0.05）. The incidences of loose stools were 20% in TCM group and 80% in the positive control group； the rate of loose stools and AWR scores at different pressures， serum concentration of LPS and protein expressions of CSF1 and TLR4 in muscle layer of colon tissue in TCM group significantly decreased， compared with the model group； colon emptying time， the average optical density of BMP2 protein in muscle layer of colon tissue， and the indexes of Chao 1， Shannon and Faith’s PD and Simpson E-mail：772699670@qq.com index of rats in TCM group were all prolonged or increased significantly， compared with the model group （P＜0.01 or P＜ E-mail：aiwangzi312@163.com 0.05）. The relative abundance ratio of Firmicutes/Bacteroidetes， from low to high， was in the order of TCM group， control group， positive control group and model group； the species composition of gut microbiota in TCM group was closer to control group， with dominant bacterial genera including Prevotella and Blautia. CONCLUSIONS Tongxie yaofang can regulate the expressions of BMP2 and CSF1， the key proteins of gut microbiota-ENS-MM crosstalk， by changing the gut microbiota， thus alleviating the abnormal hyperfunction of colon motility in IBS-D rats.

Effect of Raw and Processed Aurantii Fructus Immaturus Switched to Zhishi Shaoyaosan on Function of Brain-Gut-Microbiota Axis in Rats with Constipation-predominant Irritable Bowel Syndrome / 中国实验方剂学杂志

ObjectiveTo research the mechanism underlying the effect of raw and processed Aurantii Fructus Immaturus switched to Zhishi Shaoyaosan （ZSS） on constipation-predominant irritable bowel syndrome （C-IBS） rats via the brain-gut-microbiota axis. MethodEighty rats were randomly divided into the blank， model， positive drug （pinaverium bromide， 15.625 mg·kg-1）， raw ZSS， stir-fried ZSS， bran-fried ZSS， charcoal-fried ZSS and finished ZSS groups （3.75 g·kg-1）， with 10 rats in each group. Except for the blank group， which received intragastric administration of 0.9% sodium chloride solution at room temperature， all other groups were administered the ice solution at 0 to 4 ℃ （2 mL·d-1， for a total of 14 d） to establish the C-IBS rat model. The fecal water content and the propulsion rate of small intestine were detected after 14 d of continuous drug administration. The levels of 5-hydroxytryptamine （5-HT）， vasoactive intestinal peptide （VIP）， neuro-peptide Y （NPY）， calcitonin gene-related peptide （CGRP）， substance P （SP）， diamine oxidase （DAO） and D-lactic acid （D-LA） were detected by enzyme linked immunosorbent assay （ELISA）. Hematoxylin-eosin （HE） staining was used to observe the changes in colonic pathological injury in each group. The expression levels of cyclic adenosine monophosphate （cAMP）， protein kinase A （PKA） and aquaporin-3 （AQP3） mRNA in colon tissues were detected by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and the protein expressions of VIP and AQP3 in colon tissues were detected by Western blot. The content of short chain fatty acids （SCFAs） was determined by gas chromatography-mass spectrometry. ResultCompared with the blank group， the fecal water content and intestinal propulsion rate of rat in the model group were significantly decreased （P<0.01）， and the levels of 5-HT， VIP， CGRP and SP in serum were significantly increased. Simultaneously， the NPY levels significantly decreased （P<0.01）， the levels of DAO and D-LA in plasma were significantly increased （P<0.01）， and the mucosal epithelium of colon tissue was slightly damaged， with reduced goblet cells and significantly reduced luminal granules. The mRNA expression levels of AQP3， cAMP and PKA and the protein expression levels of AQP3 and VIP in colon tissue were significantly decreased （P<0.05， P<0.01）. The total amount of SCFAs in feces showed an obvious decreasing trend， with the contents of acetic acid， isobutyric acid， isovaleric acid， valeric acid and caproic acid decreased significantly， while the contents of propionic acid and butyric acid increased significantly （P<0.05， P<0.01）. Compared with the model group， the treatment groups increased the intestinal propulsion rate， improved the intestinal mucosal barrier function， and adjusted the level of serum brain-gut peptide in C-IBS rats （P<0.05， P<0.01）. The expression levels of AQP3， cAMP， PKA mRNA and VIP， AQP3 protein in colon tissue of rats in all treatment groups were increased. All the treatment groups had a significant downregulation of the content of SCFAs except for isobutyric acid in rat feces， and the effect of ZSS prepared by the bran-fried Aurantii Fructus Immaturus was superior than that of other ZSS. ConclusionThe raw and processed Aurantii Fructus Immaturus switched to ZSS could influence the brain-gut-microbiota axis to treat C-IBS rats and it is more reasonable to use bran-fried Aurantii Fructus Immaturus in ZSS.

Research progress on animal models for the evaluation of diarrhea-predominant irritable bowel syndrome / 中国实验动物学报

Irritable bowel syndrome(IBS)is one of the most common functional gastrointestinal disorders,of which diarrhea-predominant IBS(IBS-D)accounts for the largest proportion.The pathogenesis of IBS-D is complicated and diverse,and there is currently a lack of clinically effective drugs.The establishment of animal models is an essential tool for further studies of the disease mechanisms,evaluation of clinical efficacy,and drug development,and the preparation and evaluation standards of models are important factors affecting the quality of the research.Based on the currently accepted pathogenesis of IBS-D and the previous modeling experience of our research group,this review systematically summarizes the evaluation method used in animal models of IBS-D in terms of diarrhea observation,visceral sensitivity tests,and intestinal motility tests,to provide a reference for future studies.

Indice de calidad de vida percibida en pacientes con trastornos gastrointestinales funcionales en Buenos Aires, Argentina / Perceived Quality of Life Index in Patients with Functional Gastrointestinal Disorders at a Public Hospital in Buenos Aires, Argentina

Resumen Los trastornos gastrointestinales funcionales (TGF) son enfermedades crónicas que configuran un problema relevante en la salud pública, asociados en investigaciones previas a una peor calidad de vida. El objetivo del presente trabajo fue estudiar la calidad de vida en pacientes que acuden a un servicio de neurogastroenterología en un hospital de Argentina y compararlo con población control. Para ello, se realizó un estudio cuantitativo y transversal incluyendo población clínica diagnosticada con algún TGF (n = 35) y una muestra control sin diagnóstico de TGF (n = 37). Se encontraron diferencias significativas entre personas con TGF y sujetos control, X 2 (1, N = 70) = 30.23,p < .001 en todas las subdimensiones de la escala de calidad de vida (MQLI), exceptuando satisfacción espiritual (PE). Similar a investigaciones previas, los resultados de este estudio sugieren que, en Argentina -al igual que en otros países-, los individuos con TGF muestran una peor percepción de calidad de vida que la población general. Estos hallazgos podrían contribuir al diseño de intervenciones que contemplen variables biopsicosociales, con el objetivo de una mejoría integral en la calidad de vida de las personas que padecen estos trastornos.

Abstract Functional Gastrointestinal Disorders (FGDS) are chronic diseases that constitute a relevant public health problem, associated in previous research with a poorer quality of life. The aim of this study was to study the quality of life in patients attending a Neurogastroenterology Service at an Argentinean public hospital and compare it with a control population. A quantitative and cross-sectional study was carried out including a clinical population diagnosed with some FGD (n = 35) and a control sample without diagnosis of FGD (n = 37). Significant differences were found between people with FGD and control subjects, X 2 (1, N = 70) = 30.23, p < .001 in all sub-dimensions of the Quality of Life Index (MQLI), except Spiritual Fulfillment (SF). Similar to previous research, the results of this study suggest that individuals with FGD show a worse perception of quality of life than the general population. These findings could contribute to the design of interventions that contemplate biopsychosocial variables, with the aim of a comprehensive improvement in the quality of life of people with these disorders.

ObjectiveTo investigate the mechanism of Magnolia officinalis cortex for constipation-type irritable bowel syndrome（IBS-C） rats before and after sweating. MethodIBS-C rat model was established by gavage of ice water， and rats were randomly divided into the blank group， model group， mosapride group（1 mg·kg-1）， M. officinalis cortex group（10 g·kg-1） and sweated M. officinalis cortex group（10 g·kg-1）. The changes of body weight， fecal number and fecal water content of rats were observed， 16S rRNA sequencing was used to detect the structural changes of fecal intestinal flora in rats， the levels of 5-hydroxytryptamine（5-HT） and substance P（SP） in colonic tissues of rats were determined by enzyme-linked immunosorbent assay（ELISA）. ResultCompared with the model group， the fecal water content and fecal number of mosapride group， M. officinalis cortex group and sweated M. officinalis cortex group were significantly increased（P<0.05）. At the phylum level， the top four species of flora abundance were Firmicutes， Bacteroidetes， Spirochaetes and Proteobacteria. Compared with the blank group， the proportion of Firmicutes in the model group was significantly reduced（P<0.05）， while the proportion of Spirochaetes was significantly increased（P<0.05）. Compared with the model group， the proportion of Firmicutes and Spirochaetes in M. officinalis cortex group and sweated M. officinalis cortex group tended to be similar to that in the blank group， and the proportion of Spirochaetes in sweated M. officinalis cortex group was lower than that of M. officinalis cortex group. At the family level， the top four species of flora abundance were Lactobacillaceae， S24_7， Ruminococcaceae， Bacteroidaceae， compared with the blank group， the proportion of Lactobacillaceae in the model group decreased significantly（P<0.05）， and its proportion in the M. officinalis cortex group and sweated M. officinalis cortex group increased significantly after administration（P<0.05）， and the flora structure of the two groups tended to be similar to that of the blank group. At the genus level， the top four species of flora abundance were Lactobacillus， Unspecified_S24_7， Bacteroides and Treponema. Compared with the blank group， the proportion of Lactobacillus in the model group decreased significantly（P<0.05）， while the proportion of Treponema increased significantly（P<0.05）. Compared with the model group， ratio of bacterial structure of Lactobacillus and Treponema in the M. officinalis cortex group and sweated M. officinalis cortex group tended to be similar to those in the blank group， indicating that M. officinalis cortex could restore the intestinal microbial structure of IBS-C rats before and after sweating. Compared with the model group， the 5-HT content in mosapride group was significantly reduced（P<0.05）， the contents of 5-HT and SP in the M. officinalis cortex group and sweated M. officinalis cortex group were significantly increased（P<0.01）， and the sweated M. officinalis cortex group was higher than the M. officinalis cortex group. ConclusionM. officinalis cortex can play a therapeutic role on IBS-C rats by regulating 5-HT pathway and intestinal flora structure before and after sweating.

Herbal-moxa plaster for diarrhea type irritable bowel syndrome of spleen and kidney yang deficiency: a randomized controlled trial / 中国针灸

OBJECTIVE@#To compare the clinical efficacy between herbal-moxa plaster and moxa-box moxibustion for diarrhea type irritable bowel syndrome (IBS-D) of spleen and kidney yang deficiency.@*METHODS@#Eighty patients with IBS-D of spleen and kidney yang deficiency were randomly divided into a herbal-moxa plaster group and a moxa-box moxibustion group, 40 cases in each group. The patients in the two groups were treated with conventional acupuncture at Baihui (GV 20), Yintang (GV 24+), Zhongwan (CV 12) and bilateral Tianshu (ST 25), Yinlingquan (SP 9), and Taixi (KI 3), etc. In addition, the patients in the herbal-moxa plaster group were treated with herbal-moxa plaster (Wenyang Fuzheng ointment, composed of prepared monkshood, prepared evodia rutaecarpa, dried ginger, cinnamon, etc.) at Shenque (CV 8), Guanyuan (CV 4), Zhongwan (CV 12) and bilateral Tianshu (ST 25), Shenshu (BL 23) and Shangjuxu (ST 37); the patients in the moxa-box moxibustion group were treated with moxa-box moxibustion at the same acupoints as the herbal-moxa plaster group. The acupuncture-moxibustion treatment was provided once every other day for 4 weeks (14 treatments). Before and after treatment, the scores of clinical symptom of TCM, irritable bowel syndrome (IBS) symptom severity scale (IBS-SSS) and IBS quality of life scale (IBS-QOL) were compared between the two groups, and the clinical efficacy was evaluated.@*RESULTS@#Compared with those before treatment, each item scores and total scores of clinical symptom of TCM, and IBS-SSS scores in the two groups were reduced after treatment (P<0.05). The abdominal bloating score, stool frequency score and total score of clinical symptom of TCM as well as IBS-SSS score in the herbal-moxa plaster group were lower than those in the moxa-box moxibustion group (P<0.05). Compared with those before treatment, the IBS-QOL scores in the two groups were increased after treatment (P<0.05), and the IBS-QOL score in the herbal-moxa plaster group was higher than that in the moxa-box moxibustion group (P<0.05). The total effective rate was 92.5% (37/40) in the herbal-moxa plaster group, which was higher than 85.0% (34/40) in the moxa-box moxibustion group (P<0.05).@*CONCLUSION@#On the basis of conventional acupuncture treatment, herbal-moxa plaster could effectively improve the clinical symptoms and quality of life in IBS-D patients of spleen and kidney yang deficiency, and its efficacy is superior to that of moxa-box moxibustion.
