ABSTRACT

ObjectiveTo explore the application effect of Jianpi Huoxue prescription combined with acupuncture in patients with chronic atrophic gastritis (CAG) of gastric blood stasis type. MethodA total of 86 patients with CAG admitted to Wuhan First Hospital from November 2021 to March 2023 were selected and randomly divided into two groups. The control group was treated with conventional Western medicine, while the observation group was treated with Jianpi Huoxue prescription combined with acupuncture. The clinical efficacy, traditional Chinese medicine (TCM) syndrome score, pathological score, negative conversion rate of Helicobacter pylori (Hp), inflammatory indicators [neutrophils/lymphocytes (NLR) and interleukin (IL)-1β], changes in levels of gastric protease (PG) Ⅰ, PG Ⅰ/PG Ⅱ, and gastrin-17 (G-17), and drug safety during treatment were observed after treatment in both groups. ResultAfter treatment, the total effective rate of the observation group [95.35% (41/43)] was significantly better than that of the control group [79.07% (34/43)], and the difference was statistically significant (χ2=5.108, P<0.05). After treatment, the scores of the primary and secondary TCM syndromes in the observation group and the control group were significantly decreased (P<0.05). After treatment, the scores of primary and secondary TCM syndromes in the observation group were significantly lower than those in the control group (P<0.05). After treatment, the pathological scores of gastric mucosa atrophy, activity, chronic inflammation, intestinal metaplasia, and dysplasia were significantly lower in the observation group and control group (P<0.05). After treatment, the pathological scores of gastric mucosa atrophy, activity, chronic inflammation, intestinal metaplasia, and dysplasia in the observation group were significantly lower than those in the control group (P<0.05). After treatment, the Hp conversion rate in the observation group was significantly increased compared with the control group (P<0.05). After treatment, the levels of inflammatory indicators NLR and IL-1β in the observation group and control group were significantly lower (P<0.05), and the levels of inflammatory indicators NLR and IL-1β in the observation group were significantly lower than those in the control group (P<0.05). After treatment, the levels of PGI and PGⅠ/PGⅡ in the observation group and control group were significantly higher (P<0.05), and the levels of PGI and PGⅠ/PGⅡ in the observation group were significantly higher than those in the control group (P<0.05). After treatment, the G-17 level of the observation group and the control group was different at different time points (P<0.05), and the G-17 level of the observation group was higher at different time points than that of the control group (P<0.05). The G-17 level of the observation group had an increasing trend compared with the control group (P<0.05). There was no significant difference in the risk of adverse reactions between the two groups. ConclusionThe combination of Jianpi Huoxue prescription and acupuncture can effectively alleviate symptoms, increase Hp negative conversion rate, inhibit inflammation, and regulate PG and G-17 levels in CAG patients, thus controlling or even reversing gastric mucosal atrophy and reducing the probability of its progression to gastric cancer.

ABSTRACT

ObjectiveBased on ultra performance liquid chromatography-mass spectrometry(UPLC-MS) and non-targeted metabolomics technology to discuss the central regulatory effect of Chaishao Liujuntang on chronic atrophic gastritis(CAG) rats with liver-depression and spleen-deficiency, and to look for the correlation between cerebral cortex, hypothalamus and metabolic status of gastric tissues. MethodA CAG rat model with liver-depression and spleen-deficiency was established by chemical induction, hunger and satiety disorders, chronic restraint and tail clamping stimulation, lasting for 16 weeks. Twenty-eight Wistar rats were randomly divided into a blank group of 8 rats and a model group of 20 rats. After the completion of modeling, 4 rats in the model group were taken to observe the pathological changes of gastric mucosa. The remaining model rats were randomly divided into a model group of 8 rats and a Chaishao Liujuntang group of 8 rats. Chaishao Liujuntang group rats were given 5.1 g·kg-1 by gavage, and the remaining rats were given equal volume sterilized water by gavage for 4 weeks. Macroscopic characteristics, behavioral indicators and histopathological changes of the gastric mucosa of rats in each group were observed and compared. UPLC-MS non-targeted metabolomics was used to explore the metabolic regulation effect of Chaishao Liujuntang on the cerebral cortex, hypothalamus and stomach tissues of CAG rats with liver-depression and spleen-deficiency. Pearson correlation coefficient method was used to analyze the correlation between different tissue metabolites. ResultCompared with the model group, the macroscopic characteristics of rats in Chaishao Liujuntang group were improved, such as hair color, mental state and stool properties, and the number of times of crossing and standing in the open field experiment was significantly increased, and the static time of forced swimming was significantly reduced(P<0.01), and the gastric mucosa atrophy was reduced. The metabolic data from the cerebral cortex of rats in each group identified a total of 3 common potential biomarkers, but not enriched in pathways, 26 common potential biomarkers were identified in the hypothalamus, and the key metabolic pathways involved were mainly enriched in purine metabolism, glycerol phospholipid metabolism, D-glutamine and D-glutamic acid metabolism. Seventeen common potential biomarkers were identified in the stomach, and the key metabolic pathways involved were mainly enriched in thiamine metabolism, valine, leucine and isoleucine biosynthesis, and taurine and taurine metabolism. Correlation analysis of metabolites in different tissues revealed that multiple amino acids and their derivatives mediated metabolic connections between the cerebral cortex, hypothalamus and stomach of rats. ConclusionThe metabolic disorders in the cerebral cortex, hypothalamus and stomach of CAG rats with liver-depression and spleen-deficiency have their own characteristics, mainly manifested by changes in the content of glycerol phospholipids, fatty acids and bile acid metabolites. Moreover, Chaishao Liujuntang may play a central regulatory role in CAG rats with liver-depression and spleen-deficiency by correcting the metabolic disorders of amino acids.

ABSTRACT

ObjectiveTo mine the compatibility rules of patented traditional Chinese medicine (TCM) compound prescriptions for treating chronic atrophic gastritis (CAG) by systems pharmacology and molecular docking methods, and predict the targets and molecular mechanisms of Chinese medicinals with different efficacy in the treatment of CAG. MethodThe TCM compound prescriptions for treating CAG were extracted from the patent system of the China National Intellectual Property Administration. The active components and targets of the prescriptions were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), Traditional Chinese Medicine Integrative Database (TCMID), and UniProt. The candidate targets and pathways of CAG were obtained from GeneCards, DisGeNet, Online Mendelian Inheritance in Man (OMIM), MalaCards, Kyoto Encyclopedia of Genes and Genomes (KEGG) and Reactome. The gene ontology (GO) functional annotation and KEGG pathway enrichment were realized by R Studio 4.1.2. STRING11.0 was employed to build the protein-protein interaction (PPI) network, and AutoDock Vina 4.2.6 was used for the docking between key targets and components. ResultA total of 228 TCM compound prescriptions for treating CAG were extracted. The medicinals used in these prescriptions mainly had warm or cold nature, bitter or sweet taste, tropism to the spleen, stomach, and liver meridians, and the efficacy of tonifying Qi, regulating Qi movement, clearing heat, and activating and toniying blood. The prescriptions mainly treated CAG via p53, mitogen-activated protein kinase (MAPK), phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt), forkhead box protein O (FoxO), vascular endothelial growth factor (VEGF), and hypoxia-inducible factor-1 (HIF-1) signaling pathways. Molecular docking results confirmed that the active components in the prescriptions had docking activities with key receptor proteins. ConclusionThis study preliminarily analyzed the compatibility rules of TCM compound prescriptions in the treatment of CAG. The medicinals with different efficacy treat CAG by regulating cell proliferation, apoptosis, and oxidative stress response, preventing carcinogen production, promoting gastric acid secretion, and improving local microcirculation in a multi-target, multi-pathway, multi-link manner. The findings facilitate the research on the TCM treatment of CAG.

ABSTRACT

Chronic atrophic gastritis (CAG) is a common and intractable disease in the digestive system characterized by the reduction or disappearance of gastric mucosal glands. The intestinal metaplasia or dysplasia in CAG is called precancerous lesion, which greatly increases the risk of cancerization. Dysactivation of nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) inflammatory corpuscles can release a large number of inflammatory factors, induce inflammatory cascade reactions, and participate in the process of many diseases. As reported, the dysactivation of NLRP3 inflammatory corpuscles can cause long-term chronic inflammatory infiltration of gastric mucosa and induce the development of CAG. Mitochondrial dysfunction plays an important role in the activation of NLRP3 inflammatory corpuscles. The accumulation of reactive oxygen species (ROS) produced by mitochondrial dysfunction is the key to activating NLRP3 inflammatory corpuscles. Professor LIU Youzhang put forward the theory of "spleen-mitochondrion correlation", which holds that the spleen mainly transports water and grains, generates qi and blood, transports nutrients to the whole body, and supplies energy and materials needed by the body. Adenosine triphosphate (ATP) generated by mitochondria through the circulation of tricarboxylic acid is the main energy source of the human body. The view that both of them serve as human energy processing plants coincides in terms of physiology. Pathologically, spleen deficiency is associated with mitochondrial oxidative phosphorylation dysfunction. Pathological products such as dampness, turbidity, phlegm, and blood stasis due to failure in transportation because of spleen deficiency are consistent with metabolites generated by mitochondrial dysfunction. Based on the theory of "spleen-mitochondrion correlation", this study discussed the pathogenesis of CAG in traditional Chinese medicine (TCM), analyzed the relationship between NLRP3 inflammatory corpuscles and the pathogenesis of CAG, and proposed that the activation of NLRP3 inflammatory corpuscles by mitochondrial dysfunction was the modern biological basis of the pathogenesis of spleen deficiency in CAG. The spleen-strengthening method may be related to improving the mitochondrial function and inflammatory response of patients with CAG and alleviating the damage of gastric mucosa, providing a new idea for TCM in the prevention and treatment of CAG.

ABSTRACT

Gastric ''inflammation-cancer'' transformation stars from inflammation and ends as gastric cancer (GC), and the pathogenesis is still unclear. In China, GC features high morbidity and mortality and poor prognosis, influencing the quality of life and physical and mental health of patients. Therefore, it is of great significance to construct the prevention and treatment system for GC. Chronic atrophic gastritis (CAG) plays a key role in the occurrence, development, and outcome of gastric ''inflammation-cancer'' transformation. Modern therapies for CAG generally aim at eliminating causes and alleviating clinical symptoms, which show satisfactory short-term efficacy, but the reverse and recurrence are common. Based on the holistic view, syndrome differentiation-based treatment, and the ''inflammation-cancer'' transformation in modern medicine, traditional Chinese medicine emphasizes both prevention and treatment, with individualized therapies for CAG and GC to control the transformation. According to the pathogenesis of CAG-asthenia in origin and sthenia in superficiality and deficiency-excess in complexity, this study proposed the theory of spleen deficiency and pathogen stagnation in CAG, and believed spleen deficiency, pathogen, and stagnation are respectively the root cause of, the main factor of, and the key to ''inflammation-cancer'' transformation, respectively. Spleen deficiency and pathogen stagnation are closely related to the process of the transformation. For the treatment, the spleen-invigorating and pathogen-eliminating method should be used for invigorating the spleen to consolidate original Qi, improve the blood supply in stomach, and regulate immunity, and eliminating the pathogen to relieve stagnation, reduce the occurrence of non-controllable inflammation, and improve inflammatory micro-environment. As a result, the gastric inflammation is controlled at the early stage and the gastric ''inflammation-cancer'' transformation is blocked. The gastric mucosal lesions are blocked, delayed, or even reversed. This study provides a new idea in clinical diagnosis and treatment of CAG and in the prevention of GC.

ABSTRACT

Objective:To investigate the correlation between telomere dysfunction of human gastric mucosa and chronic atrophic gastritis (CAG).Methods:From February 12, 2019 to July 10, 2020, at Endoscopy Center, Guang′anmen Hospital, China Academy of Chinese Sciences, 30 patients received endoscopy and pathological diagnosed with CAG (CAG group) were collected, and 30 patients with chronic non-atrophic gastritis (CNAG) were collected at the same time (CNAG group). The relative telomere length was detected by real time fluorescent quantitative polymerase chain reaction. The expression of telomere repeat binding factor (TRF) 1, TRF2 and protection of telomere (POT) 1 at protein level were detected by immunohistochemical staining and semi-quantitative analysis. Spearman analysis was used to analyze the correlation between the relative telomere length of gastric mucosa and the protein expression levels of TRF1, TRF2 and POT1. Mann-Whitney U test and independent sample t test were used for statistical analysis. Results:The relative telomere length of the gastric mucosa in the CAG group was shorter than that in the CNAG group (0.67 (0.51 to 1.17) vs. 1.06(0.69 to 1.37)), and the difference was statistically significant ( U=297.00, P=0.024). The protein expression levels of TRF1, TRF2, and POT1 in the CAG group were all higher than those in the CNAG group, respectively (4.26±2.49 vs. 1.86±1.34, 10.12±2.76 vs. 8.78±2.81, 4.22±2.48 vs. 2.53±1.62), and the differences were statistically significant ( t=8.05, 3.23, 5.39; P<0.001, =0.001, and <0.001). In the CAG group, the protein expression levels of TRF2 and POT1 in gastric mucosa were negatively correlated with the relative telomere length ( r=-0.477 and -0.417, P=0.008 and 0.022). Conclusions:The telomere dysfunction is related to the pathogenesis of CAG. The change of telomere binding protein expression level is involved in the shortening of telomere and pathological process of CAG patients.

ABSTRACT

ObjectiveTo investigate the influencing factors of intestinal metaplasia or atypical hyperplasia in chronic atrophic gastritis (CAG) patients and establish a prediction model. MethodThe clinical records and laboratory examination data of 335 CAG patients treated in the department of gastroenterology of the Second Affiliated Hospital of the Anhui University of Chinese Medicine from June 2016 to June 2021 were collected. Single and multiple Logistic regression analyses were used to explore the influencing factors of intestinal metaplasia or atypical hyperplasia in CAG patients by SPSS 26.0. A prediction model was constructed based on the data of the related influencing factors. In addition, 115 CAG patients diagnosed in the First Affiliated Hospital of Anhui Medical University from June 2019 to June 2021 were selected as external validation samples to verify and evaluate the prediction efficiency of the constructed prediction model. ResultMultiple Logistic regression analysis showed that pepsinogen Ⅰ[odds ratio(OR) 0.994,95% confidence interval(CI) (0.990,0.999),P<0.05],the number of focus[OR 6.765,95% CI(3.831,11.945),P<0.01], and Helicobacter pylori (Hp) infection[OR 0.546,95% CI(0.335,0.888),P<0.05] were independent risk factors for intestinal metaplasia or atypical hyperplasia in CAG patients(P<0.05). The formula of the prediction model is as follows:P=-1.558+0.606×Hp infection-0.006×pepsinogen Ⅰ+1.912×the number of focus. The receiver operating characteristic (ROC) curve showed the specific parameters as below: the area under the ROC curve of 0.76,the Youden index of 0.443,the best cut-off value of 0.52,sensitivity of 0.533,and specificity of 0.910. The prediction model was applied to the data of patients in the validation group for validation,and the predictive efficiency of the model was tested by decision curve analysis (DCA). The results showed that the model had a good fit and high predictive value. ConclusionPepsinogen Ⅰ,the number of focus, and Hp infection are independent risk factors for intestinal metaplasia or atypical hyperplasia in CAG patients. The prediction model constructed based on these factors has a good fit and high predictive value,which can provide references for the classification of CAG patients and the formulation of individual treatment protocols.

ABSTRACT

ObjectiveTo explore the effect of Chaishao Liujuntang on Hedgehog signaling pathway in rats with chronic atrophic gastritis (CAG) of liver depression and spleen deficiency. MethodWistar rats were randomized into normal group and modeling group. CAG with the liver depression and spleen deficiency syndrome was induced in rats in the modeling group with a compound method. After modeling, they were classified into the model group, vitacoenzyme group, Chaishao Liujuntang group, GDC-0449 (blocker) group, and Chaishao Liujuntang + GDC-0449 group. Normal group and model group were given (ig) normal saline. Vitacoenzyme and Chaishao Liujuntang group received (ig) corresponding drugs at 240 mg·kg-1·d-1 and 5.1 g·kg-1·d-1, respectively, and GDC-0449 group was treated (ip) with GDC-0449 at 50 mg·kg-1·d-1. For the Chaishao Liujuntang + GDC-0449 group, rats received GDC-0449 (ip) at 50 mg·kg-1·d-1 and Chaishao Liujuntang (ig) at 5.1 g·kg-1·d-1. The administration lasted 4 weeks. The pathological morphology of rat gastric mucosa was observed based on hematoxylin-eosin (HE) staining. mRNA and protein expression of sonic hedgehog (Shh), 12th transmembrane receptor Patched1 (Ptch1), and glioma-associated oncogene homolog 1 (Gli1) in gastric mucosa tissues was detected by real-time fluorescent quantitative polymerase chain reaction (Real-time PCR) and Western blot. Content of serum interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) was determined by enzyme-linked immunosorbent assay (ELISA). ResultCompared with normal group, the model group demonstrated decrease in gland cells, glandular atrophy, large lumen volume, plasma cell infiltration, intestinal metaplasia, decrease in the mRNA and protein expression of Shh, Ptch1, and Gli1 in gastric mucosa (P<0.01), and rise of serum IL-1β and TNF-α content (P<0.01). Compared with model group, vitacoenzyme group and Chaishao Liujuntang group showed ordered cells, alleviation of gland atrophy, and no obvious inflammatory infiltration, and GDC-0499 group and Chaishao Liujuntang + GDC-0449 showed no significant improvement. Significant rise in the mRNA and protein expression of Shh, Ptch1, and Gli1 in gastric mucosa tissues of vitacoenzyme group and Chaishao Liujuntang group (P<0.01), no significant difference in serum IL-1β content and significant decrease in TNF-α content in vitacoenzyme group (P<0.01), significant reduction in content of serum IL-1β and TNF-α in Chaishao Liujuntang group (P<0.05, P<0.01) were observed compared with those in the model group. The mRNA and protein expression of Shh, Ptch1, and Gli1 in gastric mucosa and the content of serum IL-1β and TNF-α were insignificantly different between the GDC-0449 group and Chaishao Liujuntang + GDC-0449 group. ConclusionChaishao Liujuntang can effectively improve the pathological state of gastric mucosa in CAG rats with liver depression and spleen deficiency, which may be related to the activation of Hedgehog signaling pathway and the decrease of IL-1β and TNF-α content.

ABSTRACT

Chronic atrophic gastritis (CAG) and gastric intestinal metaplasia (GIM) significantly increase the risk of gastric cancer. Blocking the development of CAG and GIM would help to decrease the incidence of gastric cancer. It was revealed that eradication of Helicobacter pylori could reverse gastric mucosa atrophy. Recent studies reported that GIM could be reversed to a certain extent. Clinical studies demonstrated that Lamb′s tripe extract and vitamin B12 capsule exhibited significant reversal effects on GIM. The present study systemically reviewed the diagnosis and treatment of CAG and clinical application of Lamb′s tripe extract and vitamin B12 capsule, and established the specialist instruction that would guide the reversal treatment of CAG and GIM.

ABSTRACT

Objective:To investigate the efficacy and related factors of lamb′s tripe extract and vitamin B12 capsule (LTEVB12) in the treatment of chronic atrophic gastritis.Methods:From October 1st 2016 to April 30th 2021, 240 patients with chronic atrophic gastritis visited the Department of Gastroenterology at Xijing Hospital, Air Force Medical University were retrospectively analyzed. All patients regularly took LTEVB12 (110 U/day, 3 times/day) for six months. At the end of treatment, endoscopy and gastric mucosal biopsy were conducted. The therapeutic effects were evaluated by comparing the changes of operative link on gastritis assessment (OLGA) and operative link on gastritis assessment based on intestinal metaplasia (OLGIM) staging before and after treatment. The related factors affecting the efficacy of the drug were analyzed. Multivariate logistic regression analysis was used for statistical analysis.Results:After half a year of treatment, the reversal efficiency of atrophy and intestinal metaplasia was 45.4% (109/240) and 37.9% (91/240), respectively, and the total efficiency was 62.9% (151/240). The reversal efficiency of OLGA and OLGIM staging reversed from high stage (stage Ⅲ to Ⅳ) to low stage (stage 0 to Ⅱ) was 53.4% (63/118) and 54.5% (36/66), respectively. The results of multivariate analysis showed that female, vitamin supplementation (≥3 times/week), negative or successful eradication of Helicobacter pylori and mild inflammatory status (inflammation score: 1 to 2) were associated with improving the efficacy of LTEVB12 (odds ratio=1.798, 3.730, 2.817 and 4.631, 95% confidence interval 1.055 to 3.064, 1.197 to 11.627, 1.171 to 6.779, 1.480 to 14.493; all P<0.05). High consumption of pickled food (≥3 times/week) was associated with reducing efficacy of LTEVB12 (odds ratio=0.384, 95%confidence interval 0.200 to 0.740). Conclusion:LTEVB12 has better reversal therapeutic effect on atrophy and intestinal metaplasia, and may reduce the risk of gastric cancer in patients with chronic atrophic gastritis.

ABSTRACT

Objective:To review and summarize the current research status of traditional Chinese medicine(TCM) for the treatment of chronic atrophic gastritis(CAG),provide references and hints for relevant studies,and contribute to the further understanding of TCM and the application of TCM in the treatment of CAG with scientific evidence. Method:The PubMed and Web of Science databases were searched for relevant literature on the treatment of CAG with TCM from their establishment to August 31,2020. Eligible randomized controlled trials (RCTs) and animal studies were included according to the inclusion and exclusion criteria,and then the information of the included studies was extracted,summarized,and organized for further analysis. Result:A total of 4 RCTs and 21 animal studies (including 13 papers on compound studies,3 papers on single herb studies,and 5 papers on monomer studies) about TCM treatment for CAG were included in this study. RCTs showed that TCM could work well in improving the pathological state of gastric mucosa and clinical symptoms in patients. However,there were problems of low study quality,and non-uniform diagnostic criteria for gastric mucosal pathology and clinical efficiency evaluation. Animal experiments mainly focused on the study of drug mechanism exploration,and their results showed that TCM treatment of CAG was characterized by multi-target action. However,the animal experiments also had some problems such as inconsistence of CAG animal model establishment,positive drug selection,drug intervention methods as well as intervention cycles among different experiments. Conclusion:The efficacy of TCM in the treatment of CAG has gradually gained global recognition,but there is still a need for further standardization and unification of research methods. In the future,high-quality clinical trials and standardized animal experiments are still needed to conduct in-depth studies on the time for intervention,intervention methods,active ingredients and mechanisms of TCM,so as to make contributions to the full understanding and application of TCM in the treatment of CAG.

The rat model of CAG precancerous lesion was prepared by <italic>N</italic>-methyl-<italic>N</italic>'-nitro-<italic>N</italic>-nitrosoguanidine (MNNG)compound modeling method. weiwei Tongtiao decoction high, medium and low dose treatment groups received intragastric administration of 24, 12, 6 g·kg<sup>-1</sup> Weiwei Tongtiao decoction respectively, while Weifuchun group received 0.45 g·kg<sup>-1</sup> Weifuchun suspension, once per day for 12 weeks. The pathological changes of gastric mucosa of rats were observed by hematoxylin-eosin(HE)staining, and the mRNA and protein levels of IKK<italic>β</italic> and Bcl-2 in gastric mucosa of rats were detected by Real-time quantitative polymerase chain reaction (Real-time PCR), immunohistochemistry(IHC)and Western blot. Result:Compared with the normal group, 100% inherent gland atrophy, mild to severe intestinal metaplasia, and 25% low-grade intraepithelial neoplasia were observed under microscope in model group. All Weifuchun group and Weiwei Tongtiao decoction groups could improve the atrophy of gastric glands, moderate to severe intestinal metaplasia and pathological injury of low-grade intraepithelial neoplasia, especially at high dose group. Compared with the normal group, IKK<italic>β</italic>, Bcl-2 mRNA and protein expressions in the gastric mucosa of the model group were up-regulated (<italic>P</italic><0.01). Compared with the model group, the mRNA and protein expressions of IKK<italic>β</italic> and Bcl-2 in gastric mucosa of rats in the Weifuchun group and the Weiwei Tongtiao decoction high, medium and low dose groups were down-regulated (<italic>P</italic><0.05,<italic>P</italic><0.01), showing a dose-dependent relationship, and such levels in the Weiwei Tongtiao decoction high-dose intervention group were similar to those in normal group. Conclusion:Weiwei Tongtiao decoction can improve and even reverse gastric mucosa with CAG precancerous lesions in rats, and its intervention mechanism may be related to down-regulating the expressions of IKK<italic>β</italic> and Bcl-2 in gastric mucosa.

ABSTRACT

Objective:To explore the mechanism of Banxia Xiexintang (BXXX) in preventing and treating chronic atrophic gastritis (CAG) through Kelch-like ECH-associated protein 1 (Keap1)/nuclear factor erythroid 2-related factor 2 (Nrf2)/antioxidant response element (ARE) signaling pathway. Method:SD rats were divided into a normal group (<italic>n</italic>=12) and an experimental group for CAG model induction. The model rats were then randomly divided into a model group, a vatacoenayme (VG) group (60 mg·kg<sup>-1</sup>), and high- (280 mg·kg<sup>-1</sup>), medium- (140 mg·kg<sup>-1</sup>), and low-dose (70 mg·kg<sup>-1</sup>) BXXX groups. The doses in the BXXX groups were equivalent to 28, 14, and 7 g·kg<sup>-1</sup> crude drugs. The rats in the normal group and the model group received distilled water at an equal volume, and those in the VG group and the BXXX groups were treated correspondingly by gavage. After 12 weeks of treatment, hematoxylin-eosin (HE) staining was carried out to observe pathological changes in the gastric mucosa of CAG rats. Western blot and real-time fluorescence-based quantitative PCR was used to detect the protein and mRNA expression levels of Nrf2, glutathione S-transferase (GST), and NAD (P)H:quinone oxidoreductase 1 (NQO1) in the gastric mucosa of CAG rats. Result:Compared with the normal group, the model group showed increased protein and mRNA expression levels of Nrf2, NQO1, and GST in the gastric mucosa of the rats (<italic>P</italic><0.05), atrophic gastric mucosa, and even intestinal metaplasia. The protein and mRNA expression levels of Nrf2, NQO1, and GST in the VG group and the high- and medium-dose BXXX groups were lower than those in the model group (<italic>P</italic><0.05), and gastric mucosa atrophy and intestinal metaplasia were significantly improved, especially in the high-dose BXXX group. However, the effect in the low-dose BXXX group was not significant. Conclusion:BXXX can blunt the transcriptional activity of Nrf2, shut down Nrf2 signaling pathway, and reduce the expression levels of NQO1 and GST to achieve normal oxidation-anti-oxidation balance, which may be one of its action mechanisms in the treatment of CAG.

ABSTRACT

Objective:To observe clinical effect on chronic atrophic gastritis (CAG) with deficiency of stomach Yin when modified Shaoyao Gancaotang combined with Yiguanjian used on patients, and to study influence to prognostic risk. Method:One hundred and ten cases patients were randomly divided into control group 54 cases and observation group 56 cases. Two groups got treatment of eradication of <italic>Helicobacter pylori </italic>(Hp). Patients in control group got Yangweishu capsules, 3 grains/time, 2 times/day. Patients in observation groups when Shaoyao Gancaotang combined with Yiguanjian modified, 1 dose/day. The treatment continued for 16 weeks. Before and after treatment, gastroscope was discussed and operative link for gastritis assessment (OLGA) and operative link on intestinal-metaplasia assessment (OLGIM) were recorded, scores of atrophic degree, intestinal metaplasia degree, Hp infection, chronic inflammatory reaction, activity, endoscopic mucosal signs, dyspepsia symptoms, reported outcome patients reported outcomes (PRO) of patients with gastrointestinal diseases were graded. And to test levels of pepsinogenⅠ (PG Ⅰ),PGⅡ, gastrin-17 (G-17), cytotoxin associated gene A (CagA) and vacuolar cytotoxin (VacA). Result:The effect of patients treated in observation group was better than the effect of patients received measures in control group (<italic>Z</italic>=2.068, <italic>P</italic><0.05). Scores of atrophic degree, intestinal metaplasia degree, chronic inflammatory reaction and activity were lower than the scores of patients received measures in control group (<italic>P</italic><0.01). Levels of OLGA (<italic>Z</italic>=2.037, <italic>P</italic><0.05) and OLGIM (<italic>Z</italic>=2.014, <italic>P</italic><0.05) of patients treated in observation group were better than the levels of patients received measures in control group. And levels of PGⅠ, G-17 and PG Ⅰ/PGⅡ of patients treated in observation group were higher than the dates of patients received measures in control group (<italic>P</italic><0.01). Positive rates of CagA and VacA were all lower than the dates in control group (<italic>P</italic><0.05). And gastroscopic mucosal signs and dyspepsia symptoms and scores of PRO were all lower than dates of patients received measures in control group (<italic>P</italic><0.01). Conclusion:On the basis of eradicating Hp, treatment of Shaoyao Gancaotang with Yiguanjian modified can relieve the clinical symptoms, improve the quality of life of patients, promote mucosal repair, improve the pathological changes, reduce the degree and scope of gastric mucosal atrophy, which is conducive to delay the progression of lesions and reduce the risk of canceration when it used on CAG. It has good clinical efficacy and was worthy of further study

ABSTRACT

Based on the clinical characteristics of chronic atrophic gastritis in traditional Chinese and Western medicine, the domestic and foreign relevant literature reports and animal models of chronic atrophic as well as the clinical diagnostic indicators of traditional Chinese and western medicine, chronic atrophic gastritis evaluation standard was summarized to evaluate and analyze the coincidence degree of clinical symptoms of the existing chronic atrophic gastritis animal models. The statistical results found that modeling methods with a higher coincidence degree with the existing chronic atrophic gastritis animal models are disease and syndrome combination mode-ling, surgical modeling, multifactor comprehensive modeling and MNNG modeling. Although the animal models were reproduced by such methods as etiology, pathogenesis and disease and syndrome combination similar to those of human beings, there is still a big gap with the natural disease state. Further in-depth studies and improvement shall be made in clinical practice in the hope to provide refe-rence for clinical practice and experimental studies of chronic atrophic gastritis.

ABSTRACT

Introducción: El Helicobacter pylori se ha relacionado con el desarrollo de gastritis crónica atrófica, metaplasia intestinal y displasia, lesiones que pueden evolucionar a carcinoma gástrico. Existen investigaciones que demuestran que la erradicación de esta bacteria disminuye el riesgo de progresión histopatológica de las lesiones preneoplásicas, excepto la metaplasia intestinal y la displasia. Se realizó una revisión de los artículos publicados en las bases de datos Pubmed, Scielo, Medline y Cochrane, relacionados con el tema. Objetivo: Profundizar en los conocimientos relacionados con la infección por Helicobacter pylori y cáncer gástrico. Desarrollo: El adenocarcinoma es el tumor gástrico más frecuente y el Helicobacter pylori es el agente etiológico principal. En poblaciones de riesgo elevado, el adenocarcinoma gástrico de tipo intestinal, se precede de lesiones preneoplásicas (atrofia, metaplasia intestinal y displasia) que evoluciona al cáncer invasor. Conclusiones: Helicobacter pylori favorece la carcinogénesis gástrica, aunque existen otros factores de riesgo para el surgimiento del cáncer gástrico como son: la historia familiar, la pobre ingestión de frutas y vegetales y el bajo nivel socioeconómico(AU)


Introduction: Helicobacter pylori has been linked to the development of chronic atrophic gastritis, intestinal metaplasia, and dysplasia, lesions that can progress to gastric carcinoma. There is research showing that the eradication of this bacterium reduces the risk of histopathological progression of preneoplastic lesions, except for intestinal metaplasia and dysplasia. A bibliographic review was made of the articles published in the Pubmed, Scielo, Medline and Cochrane data bases, related to the topic, belonging to authors dedicated to the study of this problem. Objective: To go deepen in the knowledge related to Helicobacter pylori infection and gastric cancer. Development: Adenocarcinoma is the most frequent gastric tumor and Helicobacter pylori is the main etiologic agent. In high-risk populations, gastric adenocarcinoma of the intestinal type, is preceded by preneoplasic lesions (atrophy, intestinal metaplasia, and dysplasia), that progresses to invasive cancer. Conclusions: Helicobacter pylori favors gastric carcinogenesis, although there are other risk factors for the development of gastric cancer such as: family history, poor intake of fruits and vegetables, and low socioeconomic leve(AU)
