ABSTRACT
Objective:Based on database mining， the high-frequency compatibility of Caryophylli Fols as the core in formulas for treating diarrhea was analyzed， and the network pharmacology was used to elucidate the mechanism of the core drug group containing Caryophylli Fols in the treatment of diarrhea. Method:The online database of traditional Chinese medicine （TCM） was intelligently crawled by Python 3.8.1 programming， and the compatibility rules of Caryophylli Fols were analyzed， and the TCM with support≥0.30， confidence≥0.90 and lift≥1.00 was set as the core drug group of Caryophylli Fols. The components were searched and screened by TCM Systems Pharmacology Database and Analysis Platform （TCMSP）， and the disease targets were collected in Therapeutic Target Datebase （TTD）， GeneCards and DisGeNET database with "Diarrhea" as the key word. The network diagram of "TCM-ingredients-potential targets" was constructed by Cytoscape 3.7.1 software， and the network of protein-protein interaction （PPI） was constructed by STRING 11.0. Gene Ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） enrichment analysis of potential targets was analyzed by R language， and the components of the core drug group were preliminarily verified and evaluated by Discovery Studio Client 2016 software. Result:A total of 155 formulas containing Caryophylli Fols for treating diarrhea were screened， involving 54 TCMs. The analysis of association rules showed that Caryophylli Fols was strongly associated with Myristicae Semen， Glycyrrhizae Radix et Rhizoma， Aucklandiae Radix and Atractylodis Macrocephalae Rhizoma in the treatment of diarrhea. The core drug group composed of these five TCMs involved 119 kinds of TCM ingredients and 114 potential targets， of which 104 potential targets were distributed in the nervous system， and the key targets were tumor protein p53 （TP53）， transcription factor activator protein-1 （JUN）， mitogen-activated protein kinase 8 （MAPK8）， interleukin-6 （IL-6）， 90 kDa heat shock protein <italic>α</italic>A1 （HSP90AA1） and so on. GO enrichment analysis mainly involved biological processes such as the regulation of neurotransmitter levels， blood circulation， hormone-mediated signal pathway and regulation of chemical synaptic transmission. IL-17 signal pathway， helper T cell 17 （Th17） cell differentiation， epidermal growth factor receptor and salmonella infection in KEGG pathways were closely related to the treatment of diarrhea. Molecular docking showed that the key target protein had high affinity with quercetin， kaempferol and <italic>β</italic>-sitosterol. Conclusion:The multi-components， multi-targets and multi-pathways involved in the core drug group of Caryophylli Fols are closely related to inflammation and nervous system， so it is speculated that it may treat diarrhea by repairing intestinal shielding integrity and regulating the levels of neurotransmitters.
ABSTRACT
Diarrhea-predominant irritable bowel syndrome (IBS-D) is one of the common functional gastrointestinal diseases in clinical practice, its pathogenesis is diverse. Because of its sudden and lingering intractable symptoms, it seriously affects patients' work and life. IBS-D patients suffer from repeated illnesses, which often affect their lives with mental symptoms such as anxiety and depression. Anxiety and depression can also affect visceral sensation, increase intestinal sensitivity, aggravated by interaction between physical symptoms and mental symptoms. The main pathogenesis of IBS-D such as visceral hypersensitivity, gastrointestinal motility disorders, intestinal infections, and psychosocial factors are all related to brain-gut interaction disorders. Patients with IBS-D are prone to brain-gut interaction disorders due to long-term chronic mental stress. Brain-gut interaction is the main mode of regulation of gastrointestinal function in the brain-gut axis. Traditional Chinese medicine （TCM） believes that the main syndrome type of IBS-D patients is liver stagnation and spleen deficiency, while liver stagnation will be unsatisfactory, and the secretion and content of various neurotransmitters in the brain are closely related to emotions. Tongxie Yaofang is a commonly basic prescription used for the clinical treatment of IBS-D liver stagnation and spleen deficiency syndrome. It has the functions of softening the liver and replenishing the spleen, removing dampness and stopping diarrhea, and has a significant clinical effect. At present, many animal experiments and clinical studies have explored the mechanism of Tongxie Yaofang in treating IBS-D and its effect on brain-gut interaction function and brain-gut peptide content, but the main liver drainage and brain-gut interaction have not been linked. The author took the correlation between liver liver govers regulating and brain-gut interaction as the starting point, explored the mechanism of Tongxie Yaofang in treating IBS-D based on brain-gut interaction disorder, and explained the correlation between the three. Based on the research literature of Tongxie Yaofang in the past 5 years and the interaction between Tongxie Yaofang and brain-gut interaction, the author explored the effect of Tongxie Yaofang in treating IBS-D by affecting the brain-gut axis and brain-gut peptides.
ABSTRACT
Treatment for inflammatory bowel disease (IBD)is becoming a great challenge in clinical practice. Currently,treatment strategies are focused on attenuation of intestinal inflammation and autoimmune reactivity as well as surgical therapy. However,these measures cannot prevent the progression of pathophysiological process in quite a number of patients. The understanding of brain-gut interaction in the pathogenesis of IBD has shed light on the treatment of this disease. This review article discussed the importance of integrative psycho-gastrointestinal thinking and strategies targeting on the intestinal inflammation-associated psychological factors,neuroimmune abnormalities,and intestinal microbiota in the management of IBD in clinical practice.

ABSTRACT
ObjectiveTo testify the therapeutic efficacy of acupuncture in treating diarrhea-predominant irritable bowel syndrome (D-IBS) based on brain-gutinteraction.MethodEighty D-IBS patients were randomized into brain-gut interacted acupuncture group (treatment group) and a group with acupoints selected based on conventional syndrome differentiation (control group), 40 in each group. The treatment group was intervened by acupuncture by selecting the thirteen ghost acupoints (invented by SUN Si-miao) plus Tianshu (ST25), Dachangshu (BL25), etc., while the control group was by acupuncture based on conventional point selection, including Zusanli (ST36),Tianshu (ST25), Dachangshu (BL25), Ganshu (BL18), Pishu (BL20), etc., three times a week, and 10 sessions as a treatment course. The clinical efficacies were evaluated after 2 treatment courses.ResultThe two groups were generally equal to each other incomparing each dimension of the Short-form Health Survey (SF-36) before treatment, while the scores were increased after treatment in both groups; the treatment group was significantly superior to the controlgroup in comparing the scores ofrole-physical,bodily pain, general health, vitality, social role functioning, and reported health transition from the SF-36 (P<0.05).ConclusionAcupuncture based on brain-gut interaction can produce a more significant effect in treating D-IBS compared to conventional acupuncture.
