Mechanism of Sini Powder on treating irritable bowel syndrome based on network pharmacology and molecular docking / 国际中医中药杂志

Objective:To explore the molecular mechanism of comprehensive treatment of irritable bowel syndrome (IBS) from the perspective of alleviating gastrointestinal symptoms and neuropsychiatric symptoms by using network pharmacology and molecular docking.Methods:To retrieve the TCMSP database to obtaine the main active ingredients and the targets of Sini Powder, and the target genes of IBS were screened out through GeneCards and TTD databases. Then use STRING database and Cytoscape software to construct protein interaction network and screen the core genes, verifying the molecular docking of the core targets-drug component based on CB-Dock online molecular docking tool. Finally, used DAVID and Metascape databases respectively to conduct GO and KEGG pathways analysis. Results:There were 112 active ingredients of Sini Powder and 204 effective targets, 2 805 IBS-related genes, and 152 targets in total, which mainly concerning IL-17 signaling pathway, VEGF signaling pathway, NF-κB signaling pathway, dopaminergic synaptic pathway, serotonin synaptic pathway and calcium signaling pathway. Conclusion:Sini Powder could treat IBS by regulating neuroendocrine pathway, immune balance, improving mild intestinal inflammation and repairing intestinal barrier through multi-component, multi-path and multi-target ways.

Characteristics of liquid food distribution in the stomach of 52 patients with postprandial distress syndrome-predominated functional dyspepsia / 中华消化杂志

Objective To explore the distribution of the liquid food in the stomach of patients with postprandial distress syndrome (PDS)-predominated functional dyspepsia (FD)and the mechanism of its gastric dynamic dysfunction.Methods Fifty-two patients with PDS and 18 healthy volunteers underwent gastric emptying examination with ultrasound scanner provided.The proximal and distal gastric area and volume,area and volume ratio of proximal and distal gastric as well as emptying rate of proximal and distal gastric were calculated at fasting,maximum satiety,30 min,60 min,90 min and 120 min after meal. Student′s t test andχ2 test were performed for statistical analysis.Results Proximal gastric volume of PDS group at the time of fasting and 120 min after meal were (9.06±7.88)and (24.72±24.02)cm3 ,which were larger than those of healthy control group ((5 .96 ± 2.13 )cm3 ,(19.48 ± 12.32 )cm3 ),and the differences were statistically significant (t=-1 .637 and -0.875 ,both P distal gastric volume in PDS group and healthy group at fasting was 0.60 ± 0.38 and 0.46 ± 0.19, respectively,that at maximum satiety was in PDS group and healthy group 0.91 ±0.27,1 .30 ±0.48, respectively,and the differences were statistically significant (t = - 1 .505 and 3.970,both P 0.05 ).Conclusions The volume of distal stomach was larger than that of proximal stomach in PDS patients at maximum satiety in liquid food distribution,which may be the cause of decreasing emptying rate of proximal stomach.And proximal stomach dominated gastric motility in PDS patients.

Research progress of ghrelin on the functional dyspepsia / 医学研究生学报

Functional dyspepsia is a common functional gastrointestinal disease , however , the cause of functional dyspepsia has not been fully elucidated .Ghrelin is braingut petide , secreted by major endocrine cells of the stomach ( x/A like cells ) .Its recep-tor is widely distributed in the body .It has many kinds of biological effects , such as regulating growth hormone secretion , feeding and energy balance , affecting neuroendocrine and gastrointestinal function and so on .A growing number of studies have shown that Ghrelin in FD has a positive role in increasing the improvement of food intake and generating hunger , promoting gastric emptying .Ghrelin is a new hot spot in the research of FD .

Therapeutic Effect of Heat-clearing and Dampness-removing Therapy Combined with Bifico for Ulcerative Colitis and Its Influence on Tumor Necrosis Factor Alpha and Interleukin-10 in Rats / 广州中医药大学学报

Objective To observe the therapeutic effect of heat-clearing and dampness-removing therapy combined with Bifico for ulcerative colitis ( UC) induced by trinitrobenzene sulfonic acid ( TNBS), and to explore its influence on tumor necrosis factor alpha ( TNF-α) and interleukin-10 ( IL-10) in rats. Methods Forty female adult Sprague-Dawley rats were evenly randomized into five groups, namely normal control group, model group, Bifico (175 mg/kg) group, Chinese medicine group(enema with Changdiqing 3.6/kg and oral use of Changyanling Recipe l) , and Chinese medicine plus Bifico group. After treatment, the damage of colonic mucous membrane was evaluated, and expression levels of IL-10 and TNF-α in colonic mucosa were observed through immunohistochemical assay. Results The degree of colonic mucosal injury was severer and the inflammation was more obvious in the model group than those in the normal control groups ( P<0.01) , and the above changes were relieved to various degrees in the medication group ( P<0.01 compared with those in the model group) . Chinese medicine plus Bifico group had better effect on reducing colonic mucosa damage index ( CMDI) and inflammation, and on promoting the healing of colonic mucosa than Bifico group and Chinese medicine group (P<0.05 ) . The expression level of TNF-α in the colonic mucosa was markedly increased while that of IL-10 was markedly decreased in the model group ( P<0.01 compared with those in the normal control group) . The medication groups could counteract the above changes in the colonic mucosa ( P<0.01 compared with those in the model group) . The combination group and Chinese medicine group had better effect on decreasing TNF-α expression level and on increasing IL-10 expression level than Bifico group ( P<0.05) . Conclusion IL-10 and TNF-α play an important role in the pathogenesis and development of ulcerative colitis. Chinese medicine combined with Bifico has satisfactory therapeutic effect on UC rats, and its mechanism may be related with the increase of IL-10 expression level and with the decrease of TNF-α expression level.

Correlation of TCM Syndrome Patterns with Gastrointestinal Motility and Hormones in Functional Dyspepsia / 广州中医药大学学报

[Objective]To investigate the relationship of TCM syndrome patterns with gastrointestinal motility and hormones in functional dyspepsia (FD). [Methods] Among 30 cases of dyskinetic FD, 16 with liver depression and qi stagnation were allocated to Group B, 14 with spleen and stomach deficiency to Group C and 20 healthy volunteers served as control group ( Group A). Gastric evacuation, elctrogastrogram (EGG), serum motilin and migrating motor complex (MMC) wave of gastric antrum and duodenum during digestion were examined and analysed statistically. [Results]Gastric evacuation, contraction index and amplitude of phase II MMC wave, contraction amplitude and coordinated contraction of phase III MMC wave, and the main power of emptying EGG in empty stomach were decreased in Group B and Group C as compared with those in Group A,and those in Group C were lower than those in Group B, the differences being significant (P

Profile of gene differential expression in chronic gastritis with deficiency of spleen-QI patients / 中国病理生理杂志

AIM:To investigate a profile of gene differential expression in deficiency of spleen-QI syndrome(DSQ)patients.METHODS:4 DSQ patients and 4 healthy volunteers were selected.The gastric mucosa was taken to extract total RNA.The matched samples were hybridized on the gene chip.The fluorescent signals were scanned,the ratio of fluorescent value,the analysis of bioinformatics and t-test were also applied.Related genes were detected by real-time quantitated PCR.RESULTS:Between two groups,54 genes differentially expressed and 72.2% of them were down regulated.45 were genes about metabolism of nutrient substance and immunological regulation,and 71.1% were down regulated.4 had significant difference.Of 5 applied by real-time PCR,4 accorded with the results of the gene chip.CONCLUSION:The differentially expressed genes of DSQ patients are significantly down regulated,especially the genes involved in metabolism of nutrient substance and immunological regulation.
