The rhizomes of Atractylodes macrocephala Koidz improve gastrointestinal health and pregnancy outcomes in pregnant mice via modulating intestinal barrier and water-fluid metabolism.

ETHNOPHARMACOLOGICAL RELEVANCE: Baizhu (BZ) is the dried rhizome of Atractylodes macrocephala Koidz (Compositae), which invigorates the spleen, improves vital energy, stabilizes the fetus, and is widely used for treating spleen deficiency syndrome. However, the impact of BZ on gastrointestinal function during pregnancy remains unexplored. AIM OF THE STUDY: This study elucidated the ameliorative effects of BZ on gastrointestinal health and pregnancy outcomes in pregnant mice with spleen deficiency diarrhea (SDD). METHODS: To simulate an irregular human diet and overconsumption of cold and bitter foods leading to SDD, a model of pregnant mice with SDD was established using an alternate-day fasting and high-fat diet combined with oral administration of Sennae Folium. During the experiment, general indicators and diarrhea-related parameters were measured. Gastric and intestinal motility (small intestinal propulsion and gastric emptying rates) were evaluated. Serum motilin (MTL), ghrelin, growth hormone (GH), gastrin (Gas), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-c), chorionic gonadotropin ß (ß-CG), progesterone (P), and estradiol (E2) were quantified using an enzyme-linked immunosorbent assay. Pathological changes were examined by hematoxylin and eosin staining (H&E) and alcian blue periodic acid Schiff staining (AB-PAS). Immunohistochemistry and immunofluorescence were used to measure the expression levels of the intestinal barrier and water metabolism-related proteins in colonic tissues. The pregnancy rate, ovarian organ coefficient, uterus with fetus organ coefficient, small size, average fetal weight, and body length of fetal mice were calculated. RESULTS: The results showed that BZ significantly improved general indicators and diarrhea in pregnant mice with SDD, increased gastric emptying rate and small intestinal propulsion rate, elevated the levels of gastrointestinal hormones (AMS, ghrelin, GH, and Gas) in the serum, and reduced lipid levels (TC and LDL-c). It also improved colonic tissue morphology, increased the number of goblet cells, and promoted the mRNA and protein expression of occludin, claudin-1, ZO-1, AQP3, AQP4, and AQP8 in colonic tissues, downregulating the mRNA and protein expression levels of claudin-2, thereby alleviating intestinal barrier damage and regulating the balance of water and fluid metabolism. BZ also held the levels of pregnancy hormones (ß-CG, P, and E2) in the serum of pregnant mice with SDD. Moreover, it increased the pregnancy rate, ovarian organ coefficient, uterus with fetus organ coefficient, litter size, average fetal weight, and body length of fetal mice. These findings indicate that BZ can improve spleen deficiency-related symptoms in pregnant mice before and during pregnancy, regulate pregnancy-related hormones, and improve pregnancy outcomes.

ompX contribute to biofilm formation, osmotic response and swimming motility in Citrobacter werkmanii.

Citrobacter werkmanii, an aerobe and mesophilic Proteobacterium, is universal in industrial putrefaction, coastal water, and human blood. Our previous studies have discovered that outer membrane protein X (OmpX) of C. werkmanii is involved in calcium response, but the underlying mechanisms and its molecular characteristics remain elusive. To that end, the ompX gene was deleted from the genome of C. werkmanii and its phenotypic variations were thoroughly investigated in conjunction with the wild type (WT) and complementary strains using biochemical and molecular techniques such as RNA-Seq, respectively. The results demonstrated that deleting ompX reduces biofilm formation on polystyrene and glass surfaces. Meanwhile, ΔompX's swimming ability but not for its twitching or swarming abilities, was also reduced on semi-solid plates compared with WT, which was caused by inhibition of flagellar assembly genes, such as flgC, flhB, and fliE, etc. Furthermore, ompX inactivation altered susceptibility to various bactericide classes, as well as responses to Ca2+ and Mg2+ stress. In addition, when compared to WT, ΔompX captures a total of 1,357 deferentially expressed genes (DEGs), of which 465 were up-regulated and 892 were down-regulated, which can be enriched into various GO ontology and KEGG pathway terms. Furthermore, ompX, as well as ompD and ompW, can be modulated at the transcriptional levels by rbsR and tdcA. Overall, the ompX gene contributed to a variety of biological functions in C. werkmanii and could be served as a targeted site for controlling biofilm formation and developing new bactericides.

Screening of active components and preliminary mechanism exploration of Lycii Fructus for improving osteoporosis based on the zebrafish model / 药学学报

Juvenile zebrafish were used to screen the active components of Lycii Fructus for improving osteoporosis. The screening results were further verified by zebrafish adult osteoporosis model and the action mechanism was explored. Prednisolone was used as the inducer to build osteoporosis models of juvenile and adult zebrafish, and 9 groups of samples of different extracts and chemical parts of Lycii Fructus were given. Alizarin red staining was applied for observing the scale matrix mineralization and bone resorption. The activities of osteoblasts and osteoclasts were detected using alkaline phosphatase (ALP) and tartrate resistant acid phosphatase (TRAP/TRACP) staining. The expressions of bone metabolism-related genes alp, osteoprotectin (opn), osteoblast specific transcription factor (sp7), cathepsin K (ctsk), tracp, and Runt family transcription factor 2b (runx2b) in each group were determined using quantitative polymerase chain reaction. The results showed that all components of Lycii Fructus improved the formation area of the first vertebrae, the staining light density value, and the number of vertebrae joints in juvenile zebrafish and the Lycium barbarum polysaccharide (LBP) treatment group exerted the best effect. In addition, LBP prevented the formation of bone resorption lacunae in zebrafish scales, increased ALP activity, decreased TRAP activity, up-regulated the alp, sp7, and opn genes, and lowered the expressions of ctsk and tracp genes. In conclusion, LBP regulated the activity of osteoblasts and osteoclasts, reduced bone resorption, promoted bone formation and enhanced bone density, which might be the main anti-osteoporosis active fraction of Lycii Fructus. This study provided modern scientific evidence for the scientific connotation of the traditional effect of "strengthening bones and muscles" of Lycii Fructus, provided the reference for the evaluation of the anti-osteoporosis activity of traditional Chinese medicine based on zebrafish adult model, and provided beneficial enlightenment for the bone health needs of the aging society population.

Simultaneous determination of eleven volatile components in Cinnamomi Oleum by GC-MS / 中国中药杂志

A gas chromatography-triple quadrupole mass spectrometry(GC-MS) method was established for the simultaneous determination of eleven volatile components in Cinnamomi Oleum and the chemical pattern recognition was utilized to evaluate the quality of essential oil obtained from Cinnamomi Fructus medicinal materials in various habitats. The Cinnamomi Fructus medicinal materials were treated by water distillation, analyzed using GC-MS, and detected by selective ion monitoring(SIM), and the internal standards were used for quantification. The content results of Cinnamomi Oleum from various batches were analyzed by hierarchical clustering analysis(HCA), principal component analysis(PCA), and orthogonal partial least squares-discriminant analysis(OPLS-DA) for the statistic analysis. Eleven components showed good linear relationships within their respective concentration ranges(R~2>0.999 7), with average recoveries of 92.41%-102.1% and RSD of 1.2%-3.2%(n=6). The samples were classified into three categories by HCA and PCA, and 2-nonanone was screened as a marker of variability between batches in combination with OPLS-DA. This method is specific, sensitive, simple, and accurate, and the screened components can be utilized as a basis for the quality control of Cinnamomi Oleum.

DNA-free CRISPR-Cas9 gene editing of wild tetraploid tomato Solanum peruvianum using protoplast regeneration.

Wild tomatoes (Solanum peruvianum) are important genomic resources for tomato research and breeding. Development of a foreign DNA-free clustered regularly interspaced short palindromic repeat (CRISPR)-Cas delivery system has potential to mitigate public concern about genetically modified organisms. Here, we established a DNA-free CRISPR-Cas9 genome editing system based on an optimized protoplast regeneration protocol of S. peruvianum, an important resource for tomato introgression breeding. We generated mutants for genes involved in small interfering RNAs biogenesis, RNA-DEPENDENT RNA POLYMERASE 6 (SpRDR6), and SUPPRESSOR OF GENE SILENCING 3 (SpSGS3); pathogen-related peptide precursors, PATHOGENESIS-RELATED PROTEIN-1 (SpPR-1) and PROSYSTEMIN (SpProSys); and fungal resistance (MILDEW RESISTANT LOCUS O, SpMlo1) using diploid or tetraploid protoplasts derived from in vitro-grown shoots. The ploidy level of these regenerants was not affected by PEG-Ca2+-mediated transfection, CRISPR reagents, or the target genes. By karyotyping and whole genome sequencing analysis, we confirmed that CRISPR-Cas9 editing did not introduce chromosomal changes or unintended genome editing sites. All mutated genes in both diploid and tetraploid regenerants were heritable in the next generation. spsgs3 null T0 regenerants and sprdr6 null T1 progeny had wiry, sterile phenotypes in both diploid and tetraploid lines. The sterility of the spsgs3 null mutant was partially rescued, and fruits were obtained by grafting to wild-type (WT) stock and pollination with WT pollen. The resulting seeds contained the mutated alleles. Tomato yellow leaf curl virus proliferated at higher levels in spsgs3 and sprdr6 mutants than in the WT. Therefore, this protoplast regeneration technique should greatly facilitate tomato polyploidization and enable the use of CRISPR-Cas for S. peruvianum domestication and tomato breeding.

Research progress on the interactions between gut bacterial β-glucuronidases and Chinese herbal medicines / 药学学报

In traditional oral practice, the presystemic interactions with gut microbiota is an important mechanism underlying the holistic health benefits of Chinese herbal medicines (CHMs), making the study of CHMs distinct from the research of Western medicines of which the systemic exposure (level in blood) is the starting point and the core. Gut microbial metabolism complements host metabolism in maintaining metabolic homeostasis of many biologically important endogenous molecules and the disposition of numerous exogenous compounds. Among them, the widely distributed gut bacterial β-glucuronidases (BGUSs) coordinate with host UDP-glucuronosyltransferases (UGTs) to play a role in the occurrence and intervention of diseases by affecting the glucuronidation homeostasis and altering the intestinal local and/or systemic exposure of endogenous compounds and xenobiotics. On one hand, many ingredients of CHMs undergo enterohepatic circulation; On the other hand, CHMs can act on BGUSs directly or indirectly change the distribution and function of BGUSs through reprogramming gut microbiome. The multiple interactions between BGUSs and CHMs may play an important role in the overall therapeutic benefits of CHMs. This work firstly summarizes the latest research progress on BGUSs; then the physiological, pathological and pharmacological significance of BGUSs are exemplified with representative endogenous and exogenous compounds from the aspects of nutrient utilization, metabolic homeostasis, and therapeutic response based on the varied substrate spectra of BGUSs; finally, the scattered data in literature were integrated to summarize the multiple interactions between BGUSs and CHMs, highlighting the important role of BGUSs in the holistic actions of CHMs.

Role of Wnt/β-catenin Signaling Pathway in Seborrheic Alopecia and Its Intervention with Traditional Chinese Medicine： A Review / 中国实验方剂学杂志

Seborrheic alopecia is a chronic dermatological disease caused by multiple factors. It occurs frequently in young and middle-aged men aged 20-30 years. The main clinical manifestations are greasy hair， itching， excessive dandruff， receding hairline， sparse hair on the top of the head， and progressive hair loss in the frontotemporal area. Seborrheic alopecia is not fatal， but it affects the appearance of patients， seriously harming their self-esteem and bringing great psychological distress to them. The Wnt/β-catenin signaling pathway widely exists in multicellular eukaryotes and is a basic growth regulatory pathway which regulates cell proliferation and differentiation， maintains stem cells activity and organ homeostasis， and affects cell migration. At present， it has been reported in China and abroad that Wnt/β-catenin signaling pathway is closely related to the occurrence and development of seborrheic alopecia and the action mechanism of drugs. Traditional Chinese medicine （TCM） has multi-component， multi-target， and multi-pathway advantages， and it can promote the formation of hair follicle laminae， the proliferation and differentiation of hair follicle stem cells， and the periodic changes in hair follicles by regulating the Wnt/β-catenin signaling pathway， thereby alleviating seborrheic alopecia. This article reviewed the relationship of Wnt/β-catenin signaling pathway and its key target protein factors with seborrheic alopecia to clarify the important role of Wnt/β-catenin signaling pathway in seborrheic alopecia. At the same time， the TCM that targeted the Wnt/β-catenin signaling pathway to relieve seborrheic alopecia were summarized， so as to provide reference for the treatment of seborrheic alopecia and further development of new drugs.

MA Hui-fang's experience in age-related macular degeneration treated with acupuncture at Jingming (BL 1) / 中国针灸

The paper introduces professor MA Hui-fang's experience in age-related macular degeneration treated with acupuncture at Jingming (BL 1). It is believed that the basic pathogenesis of this disease refers to liver and kidney insufficiency and weakness of spleen qi. Based on the academic ideas of yang qi and meridian-collateral system, the treatment principle is proposed as "invigorating yang qi, replenishing the liver and kidney and nourishing the spleen and stomach". Regarding acupoint selection, Jingming (BL 1) is specially used, combined with the 4 front-mu points (Zhongwan [CV 12], Guanyuan [CV 4] and bilateral Tianshu [ST 25]), as well as the empirical points for eye diseases (Jingming [BL 1], Baihui [GV 20] and Zulinqi [GB 41]). Concerning to needling technique, shuci (transport needling), fenci (intermuscular needling) and yuandaoci (distal needling) are dominated. Eventually, a set of unique therapeutic method has been accumulated through professor MA Hui-fang's clinical practice in treatment of age-related macular degeneration.

Gestational diabetes mellitus decreased umbilical cord blood polyunsaturated fatty acids: a meta-analysis of observational studies.

BACKGROUND: Polyunsaturated fatty acid (PUFA) is important for the development of the fetal brain, and the retina. Gestational diabetes mellitus (GDM) may influence maternal and fetal fatty acid metabolism, in turn affecting fetal growth and development. In several studies, maternal and fetal PUFA metabolic differences have been reported between mothers with and without GDM, but not in other studies. Thus, the aim of this meta-analysis (registration number: CRD42020220448) was to compare levels of linoleic acid (LA), α-linolenic acid (ALA), arachidonic acid (AA), docosahexaenoic acid (DHA), and total n-3 and n-6 PUFA between mothers with and without GMD and their fetuses. METHODS: We performed a meta-analysis of observational studies on maternal and fetal fatty acid metabolism, published until May 2021. In addition, we performed subgroup analysis depending on the analyzed tissues (plasma/serum, erythrocyte membrane, or placenta) and the expression modes of fatty acids (concentration or percentage). RESULTS: We included 24 observational studies involving 4335 maternal datasets and 12 studies involving 1675 fetal datasets in the meta-analysis. Levels of AA, DHA, and n-6 and n-3 PUFA were lower in the cord blood of mothers with GDM than in controls (P  <  0.05). Compared to that in controls, in erythrocyte membranes, the percentages of AA, DHA, and n-6 and n-3 PUFA in total fatty acid were lower in mothers with GDM (P  <  0.05), but in plasma/serum, the percentages of AA, DHA, and n-6 PUFA in total fatty acid were higher in mothers with GDM (P  <  0.05). CONCLUSIONS: GDM appears to influence the transfer of PUFAs from mothers to fetuses. The percentage of PUFAs in maternal plasma/serum was higher, and that in erythrocyte membranes was lower in mothers with GDM compared to those with normal glucose tolerance.

Supplementation with milk enriched with complex lipids during pregnancy: A double-blind randomized controlled trial.

BACKGROUND: Gangliosides are a class of sphingolipids that are present in the cell membranes of vertebrates. Gangliosides influence a broad range of cellular processes through effects on signal transduction, being found abundantly in the brain, and having a role in neurodevelopment. OBJECTIVE: We aimed to assess the effects of maternal daily consumption of ganglioside-enriched milk vs non-enriched milk and a non-supplemented group of pregnant women on maternal ganglioside levels and pregnancy outcomes. DESIGN: Double-blind parallel randomized controlled trial. METHODS: 1,500 women aged 20-40 years were recruited in Chongqing (China) between 11 and 14 weeks of a singleton pregnancy, and randomized into three groups: Control-received standard powdered milk formulation (≥4 mg gangliosides/day); Complex milk lipid-enhanced (CML-E) group-same formulation enriched with complex milk lipids (≥8 mg gangliosides/day) from milk fat globule membrane; Reference-received no milk. Serum ganglioside levels were measured in a randomly selected subsample of 250 women per group. RESULTS: CML-E milk was associated with marginally greater total gangliosides levels in maternal serum compared to Control (13.02 vs 12.69 µg/ml; p = 0.034) but not to Reference group. CML-E milk did not affect cord blood ganglioside levels. Among the 1500 women, CML-E milk consumption was associated with a lower rate of gestational diabetes mellitus than control milk [relative risk 0.80 (95% CI 0.64, 0.99)], but which was not different to the Reference group. CML-E milk supplementation had no other effects on maternal or newborn health. CONCLUSIONS: Maternal supplementation with milk fat globule membrane, as a source of gangliosides, was not associated with any adverse health outcomes, and did not increase serum gangliosides compared with the non-supplemented reference group.

Complex patterns of circulating fatty acid levels in gestational diabetes mellitus subclasses across pregnancy.

BACKGROUND & AIMS: To investigate the relationship between maternal serum fatty acid levels and gestational diabetes mellitus (GDM) subtypes across pregnancy. METHODS: A total of 680 singleton mothers enrolled in the Complex Lipids in Mothers and Babies (CLIMB) study in Chongqing, China were included. Clinical information and serum samples were collected at gestational weeks (GWs) 11-14, 22-28, and 32-34. 75 g Oral Glucose Tolerance Test (OGTT) was conducted at GW 24-28 and GDM subtypes divided into three groups using International Association of Diabetes and Pregnancy Study Group (IADPSG) guidelines criteria: elevated fasting plasma glucose (FPG group; n = 59); 1-h and/or 2-h post-load glucose (1h/2h-PG group; n = 94); combined group (FPG&1h/2h-PG group; n = 42). Non-GDM pregnancies were included (n = 485) as controls. Twenty fatty acids were quantified in serum using gas chromatography-mass spectrometry (GC-MS) analysis. RESULTS: Overall, most serum fatty acid concentrations increased rapidly from the first to second trimester, followed by a plateauing or reduction in the third trimester (p < 0.001). In cross sectional analysis, fatty acid concentrations were significantly higher in the FPG group at GW 11-14 and decreased in the 1h/2h-PG group at GW 32-34, relative to controls. Moreover, higher α-linolenic acid (ALA; the second tertile: adjusted odds ratio [aOR] = 2.53, 95% CI: 1.17 to 5.47; the third tertile: aOR = 2.60, 95% CI: 1.20 to 5.65) and docosahexaenoic acid (DHA; the second tertile: aOR = 2.34, 95% CI: 1.10 to 4.97; the third tertile: aOR = 2.16, 95% CI: 1.00 to 4.63) were significantly associated with a higher risk of GDM in women with elevated fasting plasma glucose at GW 11-14 (first tertile as reference). CONCLUSIONS: Our findings highlight the importance of considering GDM subtypes for the individualised management of GDM in pregnancy. ALA and DHA in early pregnancy are associated with a higher risk of FPG-GDM subtype. This has widespread implications when recommending n-3 PUFAs supplementation for women with GDM.

Chemical Components of Aqueous Extracts of Melia azedarach Fruits and Their Effects on The Transcriptome of Staphylococcus aureus.

Staphylococcus aureus is the causative agent of numerous and varied clinical infections. Crude aqueous extracts of Melia azedarach fruits inhibit the planktonic growth and initial biofilm formation of S. aureus in a dose-dependent manner. Moreover, the biofilm topologies became sparse and decreased as the concentration of the aqueous extracts increased. RNA-Seq analyses revealed 532 differentially expressed genes (DEGs) after S. aureus exposure to 0.25 g/ml extracts; 319 of them were upregulated, and 213 were downregulated. The majority of DEGs were categorized into abundant sub-groups in the Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. Finally, untargeted UHPLC-MS/MS analyses of the aqueous extracts of M. azedarach fruits demonstrated a highly complex profile in positive and negative electrospray ionization modes. The extracts primarily consisted of lipids and lipid-like molecules, organic acids and their derivatives, phenylpropanoids, polyketides, organoheterocyclic compounds, and benzenoids annotated by abundant lipid maps and KEGG pathways. Overall, this study provides evidences that the aqueous extracts of M. azedarach fruits can control S. aureus infections and sought to understand the mode of action of these extracts on S. aureus.

Platycodon grandiflorum extract attenuates lipopolysaccharide-induced acute lung injury via TLR4/NF-κBp65 pathway in rats.

The traditional Chinese medicine Platycodon grandiflorum (PG) is often used for the treatment of a number of chronic inflammatory diseases. In Chinese veterinary clinic, PG is always extracted by decoction and taken orally, however, the molecular mechanism of PG extract (PE) to reduce LPS-induced inflammation, especially acute lung injury (ALI) in vivo, are not known. Thus, we have studied the anti-inflammatory effects of PE on lipopolysaccharide (LPS)-induced acute lung injury via TLR4/NF-κBp65 pathway in rat. Sprague-Dawley rats were randomly divided into 4 groups: control group, LPS group, LPS±PE low dose group and LPS±PE high dose group. All rats were given corresponding PE solution or the same amount of normal saline by intragastric administration for 7 days. On the 7th day, 1 h after the last administration, 500 µg of LPS were introduced intratracheally to establish ALI rat model, and the same volume of normal saline was given to control group. The results showed that PE reduced the levels of LPS-induced pro-inflammatory mediators including IL-6, PGE2, and TNF-α, alleviated the lung injury histologically, and down-regulated LPS-induced mRNA and protein levels of TLR4/NF-κBp65 in lung tissue. This study demonstrated that PE has the anti-inflammatory effects on LPS-induced ALI in rats through TLR4/NF-κBp65 signaling pathway, indicating that PE is an effective suppressor for anti-inflammatory activities.

Future development of Good Agricultural Practice in China under globalization of traditional herbal medicine trade / 中草药·英文版

Traditional herbal medicine (THM) is an important part of the traditional Chinese medicine culture. Due to its high medicinal potential, it should not only serve for the Chinese people's medical use, but also contribute to the world medicine, THM for the international market must be standardized and large-scale, and produced according to the “Good Agriculture Practice” (GAP). The quality of THM directly affects the patient's treatment status and safety of use. Therefore, the quality assurance of THM runs through the entire process of research and development, production and clinical practice. The standardized production and cultivation of THM is the starting point of the THM industry chain and plays a decisive role in the economic development of the THM industry. This article summarizes the development history, limitations and future development of GAP, and clarifies the opportunities for THM in the rapid development of the international and domestic Chinese medicine industry. In addition, analyzing the deficiencies that were existing in the former GAP implementation process and by suggesting science-based quality measures, it is hoped to stipulate improved GAP guidelines in the future and to lay the foundation for a modern THM international trade.

Translation of Traditional Chinese Medicine terms guided by discourse cohesion theory / 国际中医中药杂志

Due to the limitations of language, culture and professional differences, there are many problems in the translation of Traditional Chinese Medicine (TCM) terms, such as unclear translation, longtarget language and confusion of the target language. Therefore, this paper puts forward the translation strategy of TCM terms based on discourse cohesion theory, which could make full use of the characteristics of discourse cohesion and make the translated TCM terms still have the original meaning and function. In translation, we should follow the cognitive and communicative principles, create new words by using roots, affixes and vowels, optimize interpretative translation, and flexibly use transliteration translation method to improve the accuracy of translation and the conciseness and standardization of the targeted termsafter tranlation.

Data Mining of Caryophylli Fols-containing Formula and Analysis of Its Mechanism in Treatment of Diarrhea / 中国实验方剂学杂志

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.
