ABSTRACT

Gegen Qinliantang, a classic traditional Chinese medicine(TCM) compound, has been verified in modern research to possess various pharmacological effects such as anti-inflammation,anti-oxidative stress,protecting intestinal mucosal barrier, and regulating intestinal flora and immune response. Ulcerative colitis (UC) is a chronic idiopathic inflammatory disease involving the colorectal mucosa, which mainly results from genetic susceptibility, intestinal mucosal barrier damage, abnormal immune response, intestinal flora disturbance, and bile acid metabolism disorders. By reviewing the literature published in recent years, this paper sorted out the relevant pathways and mechanisms involved in the treatment of UC by Gegen Qinliantang to provide ideas for further clinical and basic research. This literature review uncovered that Gegen Qinliantang exerted the therapeutic effects against UC mainly via interleukin-6(IL-6)/Janus tyrosine kinase 2(JAK2)/signal transducer and activator of transcription 3(STAT3) signaling pathway, Toll like receptor 4(TLR4)/nuclear transcription factor-κB(NF-κB) signaling pathway,Notch signaling pathway, and matrix metalloproteinase-9(MMP-9)/p38 mitogen-activated protein kinase(p38 MAPK) signaling pathway. Gegen Qinliantang regulates the intercellular molecular transmission in multiple pathways to protect the intestinal mucosal barrier, adjust the immune response and anti-oxidative stress, and relieve UC, demonstrating the multi-target, multi-mechanism, and multi-pathway advantages of TCM compounds.

ABSTRACT

At present, the incidence and mortality of gastric cancer in China are 10.26% and 12.45%, ranking the second and third places, respectively, in the incidence and mortality of malignant tumors in China. Cancer often goes through three stages: precancerous lesions, carcinoma in situ, and invasive carcinoma. It is of great significance to advance cancer prevention and control to the stage of precancerous lesions. The popularization of digestive endoscopy-assisted diagnosis and treatment has enabled the timely diagnosis and treatment of early gastric cancer and severe dysplasia. However, the endoscopic mucosal resection is not suitable for most precancerous lesions of gastric cancer (PLGC), and the effective drugs are not available. The long-term clinical dynamic monitoring has imposed considerable physical and mental burdens on patients. Gastrointestinal microenvironment is a dynamic balance system composed of gastrointestinal flora, chemical barrier, mechanical barrier, immune barrier, and gastrointestinal nerves. The imbalance of gastric microenvironment has been proved to be the key mechanism of PLGC. According to traditional Chinese medicine (TCM), PLGC is a result of long-term interaction between deficient healthy Qi and excessive pathogens. In syndrome differentiation and treatment, PLGC is often believed to be developed from chronic gastritis. Besides, the inflammation-cancer transformation model put forward by Correa and the evolution of its TCM pathogenesis are also considered. Guided by the basic treatment principle of reinforcing healthy Qi to eliminate pathogenic factors, we determined the basic therapeutic methods as follows: invigorating spleen, clearing heat, and resolving dampness. At the same time, such methods as soothing liver and regulating Qi, resolving phlegm and dissipating mass, activating blood and resolving stasis, clearing heat and removing toxin, and tonifying deficiency can be combined based on the results of syndrome differentiation. After discussing the correlation between the imbalance of gastric microenvironment and PLGC and summarizing TCM intervention methods and mechanisms against PLGC from the perspective of gastric microenvironment regulation, this paper believed that TCM improved the gastric microenvironment by regulating the disorder of gastric flora, eliminating the gastric mucosal inflammation, and relieving the abnormal immune response, thereby preventing and controlling the PLGC.

ABSTRACT

OBJECTIVE@#To investigate the mechanism of Tojapride, a Chinese herbal formula extract, on strengthening the barrier function of esophageal epithelium in rats with reflux esophagitis (RE).@*METHODS@#Ten out of 85 SD rats were randomly selected as the sham group (n10), and 75 rats were developed a reflux esophagitis model (RE) by the esophageal and duodenal side-to-side anastomosis. Fifty successful modeling rats were divided into different medicated groups through a random number table including the model, low-, medium-, and high-dose of Tojapride as well as omeprazole groups (n10). Three doses of Tojapride [5.73, 11.46, 22.92 g/(kg•d)] and omeprazole [4.17 mg/(kg•d)] were administrated intragastrically twice daily for 3 weeks. And the rats in the sham and model groups were administered 10 mL/kg distilled water. Gastric fluid was collected and the supernatant was kept to measure for volume, pH value and acidity. Esophageal tissues were isolated to monitor the morphological changes through hematoxylin-eosin (HE) staining, and esophageal epithelial ultrastructure was observed by transmission electron microscopy. The expressions of nuclear factor kappa-light-chain-enhancer of activated B cells p65 (NF-KBp65), κB kinase beta (IKKß), occludin, and zonula occludens-1 (ZO-1) in the esophageal tissues were measured by immunohistochemistry and Western blot, respectively.@*RESULTS@#The gastric pH value in the model group was significantly lower than the sham group (P<0.05). Compared with the model group, gastric pH value in the omeprazole and medium-dose of Tojapride groups were significantly higher (P<0.05). A large area of ulceration was found on the esophageal mucosa from the model rats, while varying degrees of congestion and partially visible erosion was observed in the remaining groups. Remarkable increase in cell gap width and decrease in desmosome count was seen in RE rats and the effect was reversed by Tojapride treatment. Compared with the sham group, the IKKß levels were significantly higher in the model group (P<0.05). However, the IKKß levels were down-regulated after treatment by all doses of Tojapride (P<0.01 or P<0.05). The occluding and ZO-1 levels decreased in the model group compared with the sham group (Ps0.01 or Ps0.05), while both indices were significantly up-regulated in the Tojapride-treated groups (P<0.01 or P<0.05).@*CONCLUSIONS@#Tojapride could improve the pathological conditions of esophageal epithelium in RE rats. The underlying mechanisms may involve in down-regulating the IKKß expression and elevating ZO-1 and occludin expression, thereby alleviating the inflammation of the esophagus and strengthening the barrier function of the esophageal epithelium.

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

Objective: To analyze medication rules of national medical masters in the treatment of stomachache by data mining. Method: Prescriptions were collected from 9 works as well as the first batch of national medical masters' medical cases and prescriptions for stomachache recorded in CNKI. Then, Microsoft Excel 2016 was adopted for analyzing the frequencies, properties, flavors and meridian tropisms of herbs, the Apriori algorithm provided by SPSS Clementine 12.0 software was used to analyze association rules of the herbs, and factor analysis was conducted by SPSS 19.0 software. Result: A total of 175 prescriptions containing 230 herbs were selected. The top five herbs used in frequency ranking were Glycyrrhizae Radix et Rhizoma, Paeoniae Radix Alba, Pinelliae Rhizoma, Atractylodis Macrocephalae Rhizoma, Poria. The medical properties with high usage frequency were warm, mild and slight cold. The flavors were sweet, bitter and pungent. Meridian tropisms were spleen, stomach and lung. Herbs for regulating Qi, tonifying Qi and promoting digestion ranked top three according to the classification of efficacy. The association rules analysis showed that the highest confidence and support of the related drugs was Atractylodis Macrocephalae Rhizoma→Codonopsis Radix-Poria, which reflected treatment characteristics of national medical masters with Sijunzitang as the basic prescription for tonifying Qi. A total of 12 strongly association rules of 2-drug pairs were obtained by association rules, and the most commonly used of which was Paeoniae Radix Alba-Glycyrrhizae Radix et Rhizoma. Nine common factors were respectively extracted by factor analysis. Conclusion: Herbs used in the prescriptions of national medical masters for treatment of stomachache are often with the actions of regulating Qi, invigorating deficiency and benefiting Qi, in addition, Shaoyao Gancaotang is often used to generate Yin and relieve pain.

ABSTRACT

<p><b>OBJECTIVE</b>To explore the effect of Chang'an No. I Recipe (CA) on 5-hydroxytryptamine signal system and mRNA expression levels of hippocampal brain derived neurotrophic factor (BDNF) in visceral hypersensitivity model rats with irritable bowel syndrome (IBS).</p><p><b>METHODS</b>IBS visceral hypersensitivity rat models were established by combined chronic restraint stress and forced swimming. Successfully modeled rats were randomly divided into the model group, the Dicetelgroup (27 mg/kg) , the Fluoxetine group (3.6 mg/kg), the high dose CA group (22.6 mg/kg), the medium dose CA group (11.3 mg/kg), and the low dose CA group (5.7 mg/kg) according to body weight, 9 in each group. Besides, a normal control group with 10 rats was set up. Corresponding medication was administered to rats in each treatment group. Equal volume of physiological saline was administered to rats in the model group by gastrogavage. All medication was performed once per day for a total of 14 days. Pain threshold was determined by abdominal withdrawal reflex (AWR). Changes of colon 5-HT levels were determined by immunohistochemical assay. mRNA expression levels of hippocampal 5-hydroxytryptamine 1A receptor (5-HT1a) and BDNF were detected by immunofluorescent RT-PCR.</p><p><b>RESULTS</b>Compared with the normal control group before treatment, pain threshold was obviously lowered in proctectasia rats of each group (P < 0.01). Compared with the normal control group after treatment, pain threshold was obviously lowered in rats of the model group; colon 5-HT levels, mRNA expression levels of hippocampal 5-HT1a and BDNF were obviously elevated (P < 0.01). Compared with the model group, pain threshold was obviously elevated in the Fluoxetine group and all CA groups; colon 5-HT levels were obviously reduced in the Dicetel group, high and medium dose CA groups (P < 0.05, P < 0.01); mRNA expression levels of hippocampal 5-HT1a and BDNF were obviously reduced in each CA group (P < 0.01); mRNA expression levels of hippocampal BDNF were obviously reduced in the Fluoxetine group (P < 0.01).</p><p><b>CONCLUSIONS</b>The target points of CA were involved in brain and gut. CA could reduce pain threshold of proctectasia rats, down-regulate colon mucosal 5-HT levels, and lower mRNA expression levels of BDNF and 5-HT1a in rat hippocampus.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To explore the effect of Ronggan Mixture (RM) on immunoregulation and hepatocyte apoptosis-related factors in concanavalin A (Con A) induced acute immunological liver injury mice.</p><p><b>METHODS</b>Totally 60 hepatitis B virus (HBV) transgenic mice were randomly divided into 6 groups, i.e., the blank control group, the model group, the RM group, the Herba Artemisiae Scopariae (HAS) group, the Yinchenhao Decoction (YD) group, and the Bifendate group, 10 mice in each group. The acute immunological liver injury model was established by tail vein injection of ConA. Fourteen days before modeling, normal saline was administered to mice in the blank control group and the model group. RM, YD, HAS decoction, and Bifendate solution was respectively given to mice in the RM group, the YD group, the HAS group, and the Bifendate group. The medication was performed once daily. One h after the last gastrogavage, phosphate buffer solution (PBS) was injected to mice in the blank control group from the tail vein. Modeling was conducted by injecting Con A at 3 microg/g body weight from the tail vein. Mice were sacrificed 8 h after modeling. Blood or tissue samples were collected to detect lab indicators such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil), tumor necrosis factor alpha (TNF-alpha), interferon gamma (INF-gamma), IL-4, IL-10, Fas, FasL, Bax, and bcl-2.</p><p><b>RESULTS</b>There was significant difference in all lab indicators between the normal group and the blank control group (P < 0.05, P < 0.01). Compared with the model group, ALT and AST levels were significantly lower in the RM group and the Bifendate group (P < 0.01); TBil significantly decreased in the RM group (P < 0.01). The expression level of TNF-alpha decreased in the RM group (P <0.05). The expression level of IFN-gamma decreased in the RM group and the YD group (P < 0.05). The expression level of IL-4 could be elevated in all medicated groups (P < 0.05). RM could elevate the expression level of IL-10 (P < 0.05). The expression level of Fas in the liver tissue decreased in the RM group and the YD group (P < 0.05). The expression level of FasL decreased and the expression of bcl-2 gene increased in the RM group (both P < 0.05). The expression level of Bax was down-regulated in the RM group and the YD group (P < 0.05). The ratio of bcl-2/Bax was up-regulated in the RM group (P < 0.05). Meanwhile, RM showed better effect in decreasing expressions of ALT and AST than HAS (P < 0.05). The effect of increasing IL-10 expression levels was better in the RM group than in the YD group (P < 0.01). The effect of decreasing expressions of Fas and FasL was better in the RM group than in the HAS group, the YD group, and the Bifendate group (P < 0.05). The effect of enhancing the expression of IL-10 in the liver tissue was better in the RM group than in the HAS group (P < 0. 05).</p><p><b>CONCLUSION</b>RM had protective effect on Con A induced acute immunological liver injury mice, which might be achieved by changing the immunological balance of Thl/Th2 factors (decreasing expressions of TNF-alpha and IFN-gamma, elevating expressions of IL-10 and IL-4) and regulating hepatocyte apoptosis-related factors (down-regulating gene expressions of Fas, FasL, and Bax; up-regulating bcl-2 gene expression, and up-regulating the bcl-2/Bax ratio).</p>

ABSTRACT

<p><b>OBJECTIVE</b>The pathogenesis of irritable bowel syndrome (IBS), a functional gastrointestinal disorder, is poorly understood. Treatment by Chinese medicine and pharmacy (CMP) is superior to treatment by Western medicine (WM). Therefore, we aimed to analyze Chinese medical experts' experiences in treating IBS by data mining.</p><p><b>METHODS</b>By retrieving related literatures from 1994 to 2012 from CNKI, we chose proved cases and screened effective medical records to establish a database using structural electronic medical case collecting system and data mining. The thinking ways of modern physicians in diagnosis and treatment of IBS were analyzed.</p><p><b>RESULTS</b>Totally 116 medical cases from 46 Chinese medical experts were recruited and analyzed. Results showed that Gan depression and Pi deficiency were most basic syndrome elements. In addition, cold dampness, damp heat, yang deficiency, and Shen deficiency were main elements for the development of diarrhea predominant IBS (IBS-D). Qi stagnation, yin deficiency, qi deficiency, and blood stasis were main elements for the development of constipation predominant IBS (IBS-C). Soothing Gan-qi and strengthening Pi was the most important treatment method. White peony root, prepared atractylodes, prepared licorice, tangerine peel, poria, bupleurum, Radix sileris, lanceolata, and Radix aucklandiae were the most common Chinese herbs used in treating IBS.</p><p><b>CONCLUSIONS</b>(1) Gan depression and Pi deficiency was the main pathogenesis for IBS. Diagnosis and treatment of IBS should be performed clinically according to its development. Tongxie Yao-fang should be used as the basic prescription with modification according to syndrome differentiation. (2) Data mining will have a wide application prospect in studying medical cases.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To explore the effects of Ronggan Mixture (RGM) on cell apoptosis by observing the expressions of apoptosis-related genes (Fasl and Bcl-2) in transgenic mice with chronic liver immune injury induced by concanavalin A (ConA).</p><p><b>METHODS</b>Seventy-four transgenic mice were divided into 6 groups, the model group, the normal group, and the treated groups treated respectively with biphenyldicarboxylate (DDB), oriental wormwood (OWW), Yinchenhao Decoction (YCHD) and RGM. Pathologic changes of liver tissue were observed by light microscopy, number of apoptotic cells were determined by TUNEL method, and expressions of apoptosis-related genes, Fasl and Bcl-2, in hepatic T lymphocyte were detected by flow cytometer.</p><p><b>RESULTS</b>Evident pathological changes of liver appeared in the model mice, showed severely destroyed structure of hepatic lobules. As compared with the model group, the changes of liver fibrosis and cell necrosis were much lessened in the RGM group and the YCHD group (P < 0.05). The protein expression of apoptotic gene Fasl and the apoptotic index in the model group were higher than those in the normal group (P < 0.05), but that of the apoptotic inhibiting gene, Bcl-2, in model mice was similar to that in normal mice. As compared with the model group, apoptosis index decreased (P < 0.01), levels of Fasl expression was lower and Bcl-2 expression was higher in the RGM group and the YCHD group (P < 0.05, P < 0.01), and the effect of the two was similar, but significantly superior to that of OWW and DDB (P < 0.05 or P < 0.01).</p><p><b>CONCLUSION</b>The Chinese compound, RGM and YCHD can not only relieve the hepatic pathological injury, but also reduce the cell apoptosis in chronic liver immune injury mice through regulating the expressions of Fasl and Bcl-2.</p>
