RESUMO
Objective:To investigate the clinical efficacy of Danggui Shaoyao powder combined with folic acid tablets in the treatment of chronic atrophic gastritis. Methods:A total of 90 patients with chronic atrophic gastritis who were treated at Longyou Branch, Sir Run Run Shaw Hospital, Zhejiang University from March 2021 to March 2022 were included in this study. They were randomly divided into a control group and an experimental group, with 45 patients per group. The control group was treated with folic acid tablets, while the experimental group was treated with Danggui Shaoyao powder combined with folic acid tablets. Before and after treatment, traditional Chinese medicine syndrome scores, gastroscopy and pathology scores, and inflammatory factor levels were compared between the two groups. Clinical efficacy was compared between the two groups. Results:The amplitudes of decreases in traditional Chinese medicine syndrome score in the experimental group [acid reflux (0.57 ± 0.19) points and epigastric pain (0.84 ± 1.36) points] were significantly greater than those in the control group [acid reflux (1.46 ± 0.39) points, epigastric pain (1.52 ± 1.41) points, t = 4.86, 6.52, both P < 0.05]. Inflammatory factor levels in the experimental group [tumor necrosis factor-α (1.03 ± 0.11) μg/L, interleukin-6 (8.15 ± 1.42) ng/L, C-reactive protein (6.55 ± 0.98) mg/L] were significantly lower than those in the control group [tumor necrosis factor-α (1.73 ± 0.14) μg/L, interleukin-6 (12.24 ± 1.48) ng/L, C-reactive protein (10.23 ± 1.03) mg/L, t = 4.52, 7.66, 6.95, all P < 0.05]. The gastroscopy and pathological scores in the experimental group [intestinal metaplasia (0.78 ± 0.35) points, dysplasia (0.30 ± 0.10) points] were significantly lower than those in the control group [intestinal metaplasia (1.31 ± 0.38) points, dysplasia (0.68 ± 0.12) points, t = 4.13, 3.85, both P < 0.05]. The overall response rate in the experimental group was 93.33% (42/45), which was significantly higher than 77.78% (35/45) in the control group ( χ2 = 4.40, P < 0.05). Conclusion:Danggui Shaoyao powder combined with folic acid tablets in the treatment of chronic atrophic gastritis can effectively improve traditional Chinese medicine syndromes, reduce the level of inflammatory factors, and have a good clinical effect.
RESUMO
Objective:To evaluate the clinical effect of treatment of activating blood and removing blood stasis, invigorating the spleen and soothing the liver for the patients with gastric collateral stasis syndrome and chronic atrophic gastritis (CAG).Methods:Randomized controlled trial. A total of 68 CAG patients admitted to the Huairou Hospital of Traditional Chinese Medicine from January 2018 to January 2021 who met the selection criteria were divided into 2 groups according to the random number table method, with 34 in each group. The control group received conventional western medicine treatment, such as inhibition of acid, protecting the gastric mucosa, and the observation group was treated with Traditional Chinese Medicine (TCM) herbal prescription of activating blood and removing blood stasis, invigorating the spleen and soothing the liver. Both groups were treated for 12 weeks. TCM symptom scores were performed before and after treatment. The serum level of pepsinogen Ⅰ(PG Ⅰ), pepsinogen Ⅱ (PGⅡ) were detected by ELISA, and the PG Ⅰ/PG Ⅱ ratio was calculated. Gastroscopic biopsy was performed to observe the changes of intestinal metaplasia of gastric mucosa and glandular atrophy, and to evaluate the clinical efficacy.Results:The total responsive rate was 85.3% (29/34) in the study group and 58.8% (20/34) in the control group. There was significant difference between the two groups ( χ2=9.35, P=0.030). After treatment, the scores of stomachache, fullness of feeling in the observation group were significantly lower than those in the control group ( t=2.97, 3.80, P<0.05). After treatment, the level of serum PG Ⅰ[(76.21 ± 17.35) mg/L vs. (66.8 ± 18.77) mg/L, t=2.15] and PG Ⅰ/PG Ⅱ [(4.67 ± 0.99) vs. (3.90± 1.25), t=2.81] in the study group were significantly higher than those in the control group ( P<0.05), and PG Ⅱ [(16.36 ± 1.85) mg/L vs. (17.42 ± 2.05) mg/L, t=2.24] was significantly lower than that of the control group ( P<0.05). After treatment, intestinal metaplasia and glandular atrophy was significantly more improved or reversed than those in the control group ( χ2=20.67,9.33, P<0.05). Conclusion:The methods of activating blood and removing blood stasis, invigorating the spleen and soothing the liver can reverse the precancerous lesions of patients with gastric collateral stasis syndrome of chronic atrophic gastritis and have a good prognosis.
RESUMO
Precancerous lesions of gastric cancer (PLGC) is a pathological change accompanied by intestinal metaplasia and dysplasia on the basis of chronic atrophic gastritis. It is also an important stage of "inflammation-cancer transformation" on gastric mucosa. Paying attention to the intervention of PLGC has important value and significance for the secondary prevention of gastric cancer. PLGC has the characteristics of occult onset, toxin damaging collaterals, and long course of disease, which is highly consistent to the pathogenesis characteristics of incubative pathogenic factors. Based on the relevance of incubative pathogenic factors and PLGC, treatment of PLGC from the perspective of incubative pathogenic factors should be mainly strengthening the spleen and stomach, and combined with the methods of regulating qi and dissipating dampness, and removing blood stasis and detoxification. It should also pay attention to the prognosis.Paying attention to the body-mind treatment can reduce the re-occurrence , so as to provide a new way of thinking for treating PLGC from incubative pathogenic factors.
RESUMO
Objective:To investigate the correlation of serum pro-gastrin-releasing peptide (ProGRP), sugar chain antigen 242(CA242), procalcitonin(PCT) levels in patients with chronic atrophic gastritis (CAG) with intestinal metaplasia and Helicobacter pylori(Hp) infection and prognosis.Methods:One hundred patients with CAG intestinal metaplasia in Emergency General Hospital were selected as the research objects, and they were divided into infection group (75 cases) and non-infected group (25 cases) according to whether they had Hp infection. The clinical data, levels of serum ProGRP, CA242, and PCT were compared between the two groups, and the diagnostic value of the combination of serum indicators in the diagnosis of Hp infection in CAG intestinal metaplasia patients and their correlation with prognosis were analyzed.Results:The degree of atrophy and intestinal metaplasia in the infected group were higher than those in the non-infected group ( P<0.05). The levels of serum ProGRP, CA242 and PCT in the infected group were higher than those in the non-infected group: (159.41 ± 42.38) ng/L vs. (105.84 ± 18.29) ng/L, (7.24 ± 2.28) kU/L vs. (4.12 ± 1.30) kU/L, (3.84 ± 1.12)μg/L vs. (2.57 ± 0.82) μg/L, there were statistical differences ( P<0.05). The results of Spearman analysis showed that the levels of ProGRP, CA242, PCT had positive correlation with atrophy degree ( r = 0.614, 0.629, 0.672, P<0.05), and had positive correlation with intestinal metaplasia degree ( r = 0.574, 0.591, 0.603, P<0.05). The area under the curve (AUC) for the combined diagnosis of Hp infection in patients with CAG intestinal metaplasia by serum ProGRP, CA242, and PCT was 0.874 (95% CI 0.793 - 0.932), the diagnostic sensitivity and specificity were 76.00% and 92.00%, respectively. The incidence of gastric neoplasms in patients with Hp positive combined diagnosis of serum ProGRP, CA242, and PCT within 2 years (11.86%) was higher than that of negative patients (0), but the difference was not statistically significant ( P>0.05). Conclusions:The levels of serum ProGRP, CA242 and PCT in patients with CAG intestinal metaplasia are closely related to Hp infection. The combination of various indicators has high application value in the diagnosis of Hp infection.
RESUMO
Objective:To investigate the mechanism of Xianglian Huazhuo Decoction in treating chronic atrophic gastritis (CAG) rats by detecting the protein and gene expressions of Wnt1, GSK-3β, β-catenin in Wnt signaling pathway.Methods:Totally 60 Wistar rats were randomly divided into blank group and model group. The CAG model was established by MNNG free drink combined with sodium salicylate gavage combined with abnormal hunger and satiety. After model establishment, the rats were randomly divided into model group, Xianglian Huazhuo Group and folic acid group. Folic acid group received the folic acid water solution 1.3 mg/kg for gavage; the Xianglian Huazhuo Group received Xianglian Huazhuo Decoction 15.5 g/kg for gavage; the blank group and the model group received the same volume of purified water for gavage. After 8 weeks of intervention, the general state and the atrophic degree of gastric mucosa were observed. The expressions of Wnt1, GSK-3β and β-catenin were detected by immunohistochemical method, and the mRNA expression of β-catenin expression was detected by real-time quantitative polymerase chain reaction PCR.Results:The general condition of rats in Xianglian Huazhuo group was improved, the atrophy of gastric mucosa was improved, and the effect was better than that in folic acid group. Compared with the model group, the positive area ratio of Wnt1 decreased in Xianglian Huazhuo group ( P<0.05), and the positive area ratio of β-catenin decreased in folic acid group and Xianglian Huazhuo group ( P<0.05 or P<0.01), the positive area ratio of GSK-3β increased ( P<0.05), and the β-catenin mRNA level of Xianglian Huazhuo group decreased ( P<0.05). Conciusion Xianglian Huazhuo Decoction may increase GSK-3β by downregulating abnormal expression of Wnt1, promoting β-catenin to degrade normally, thereby blocking the abnormal activation of the Wnt signaling pathway, delaying or reversing CAG carcinogenesis to a certain extent, and exerting therapeutic effects.

RESUMO
Autoimmune atrophic gastritis (AAG) is a slowly progressive, immune‐mediated disorder with unspecific and subtle clinical manifestations. With the widespread use of endoscopy, especially the progression of early gastric cancer screening, it has increased awareness that AAG is a pre‐neoplastic condition, predisposing to the development of both type 1 neuroendocrine tumors and gastric adenocarcinoma. The diagnosis of AAG is based on distinctive endoscopic and histological features and serum intrinsic factor and/or parietal cell autoantibody positivity, which is challenging due to its wide clinical spectrum-ranging from a symptomless to a disabling disease course. This article summarizes the research progress of AAG in recent years, analyzes the reasons for delayed diagnosis of AAG, and proposes coping strategies.

RESUMO
Introducción. En Asia y Europa, el sistema OLGA ha sido útil como marcador de riesgo de cáncer gástrico. Sin embargo, su utilidad en poblaciones de alto riesgo en Colombia aún se desconoce. Objetivo. Establecer si los estadios OLGA se asocian con un mayor riesgo de cáncer y displasia en una población de alto riesgo en Colombia y determinar la capacidad diagnóstica de la escala para evaluar dicho riesgo. Materiales y métodos. Se realizó un estudio multicéntrico con pacientes con cáncer gástrico y displasia (casos), y pacientes con atrofia y metaplasia intestinal (controles), provenientes de tres centros de una zona de alto riesgo de cáncer gástrico en Colombia. Se incluyeron 506 pacientes cuyo estudio endoscópico e histopatológico fue realizado mediante el sistema de Sydney y la estadificación de OLGA propuesta por Rugge. El efecto de cada variable de interés sobre la enfermedad (cáncer gástrico y displasia) se evaluó mediante modelos bivariados y multivariados. Un valor de p menor de 0,05 se consideró estadísticamente significativo. Resultados. Los estadios elevados del sistema OLGA (III-IV) se asociaron con un mayor riesgo de displasia y cáncer gástrico (OR ajustado = 8,71; IC95 % = 5,09-14,9; p=0,001) con una sensibilidad del 54,9 %, especificidad del 89,3 % y una razón de probabilidad positiva de 5,17. Conclusiones. El estadio OLGA es un marcador de riesgo de cáncer gástrico y displasia en la población de estudio. Se recomienda su implementación como estrategia para optimizar el diagnóstico oportuno y el seguimiento de pacientes con mayor riesgo.
Introduction. The OLGA system has been proved to be useful in Asia and Europe as a risk marker of gastric cancer. However, its usefulness in high-risk populations in Colombia is still unknown. Objective. To assess potential associations between the OLGA staging system and an increased risk of gastric cancer and dysplasia in a high-risk Colombian population and to establish diagnostic capacity of the scale to assess the risk. Materials and methods. We carried out a multicenter study including patients with cancer and dysplasia (cases) and patients with atrophy and intestinal metaplasia (controls). A total of 506 patients were recruited from three centers in an area with a high risk population in Colombia. The endoscopic and histopathologic studies were evaluated according to the Sydney system and the OLGA staging system proposed by Rugge. The effect of each variable on the disease (gastric cancer and dysplasia) was evaluated using bivariate and multivariate models. Statistical significance was set considering a p value inferior to 0.05. Results. Advanced stages of the OLGA system (III-IV) were associated with a higher risk of dysplasia and gastric cancer (adjusted OR = 8.71; CI95% = 5.09-14.9; p=0.001), sensitivity=54.9%, specificity=89.3% and positive likelihood ratio=5.17. Conclusions. The OLGA staging system is a risk marker for gastric cancer and dysplasia in the studied population. We recommend its implementation to improve the timely diagnosis and follow-up of patients with the highest cancer risk.
RESUMO
Objetivos: Se buscó determinar si las endoscopias que cumplieron el protocolo Sydney en una población de Antioquia tuvieron una detección mayor de H. pylori y sus lesiones asociadas que las endoscopias que sólo tomaron muestras de antro. Materiales y métodos: Realizamos un estudio retrospectivo, trasversal y descriptivo. Se incluyeron pacientes adultos sometidos a endoscopia superior. Se dividieron los pacientes en dos grupos según si se siguió o no el protocolo Sydney y se midió la frecuencia de detección de H. pylori, y lesiones premalignas. Resultados: Se incluyeron 261 participantes, a 88 se les tomó el protocolo de Sydney y a 173 se les tomaron muestras exclusivamente de antro gástrico. La indicación principal de endoscopia fue dispepsia (35,6%). La detección de H. pylori, gastritis atrófica y metaplasia intestinal fue del 36,4%, 19,3% y 20,5% respectivamente en el grupo Sydney, y 30,1%, 11,6% y 9,8% en el grupo control. En el grupo Sydney, la detección de H. pylori fue mayor en antro y cuerpo (26,1%) que en antro (6,8%) o cuerpo (3,4%) por separado. La detección de gastritis atrófica y metaplasia intestinal fue mayor en antro solamente (10,2% y 11,4% respectivamente) que en antro y cuerpo o cuerpo por separado. Conclusiones: La omisión del protocolo Sydney reduce la detección de H. pylori, gastritis atrófica y metaplasia intestinal en un 9,4%, 29,4% y 27,7% respectivamente. Se debe implementar el protocolo sistemáticamente en todo centro de endoscopia digestiva.
Objectives: We sought to determine whether the endoscopies that met the Sydney protocol in a population of Antioquia had a greater detection of H. pylori and their associated lesions than the endoscopies that only took antrum samples. Materials and methods: We carried out a retrospective, cross-sectional and descriptive study. Adult patients undergoing upper endoscopy were included. Patients were divided into two groups depending on Sydney protocol compliance. The detection frequency was measured for H. pylori and premalignant lesions. Results: 261 participants were included, 88 from which biopsies were taken with the Sydney protocol and 173 with biopsies taken exclusively from the gastric antrum. The main endoscopy indication was dyspepsia (35.6%). The detection of H. pylori, atrophic gastritis and intestinal metaplasia was 36.4%, 19.3% and 20.5% respectively in the Sydney group, and 30.1%, 11.6% and 9.8% in the control group. In the Sydney group, the detection of H. pylori was higher in the antrum and body (26.1%) than in antrum (6.8%) or body (3.4%) separately. The detection of atrophic gastritis and intestinal metaplasia was higher in antrum only (10.2% and 11.4% respectively) than in antrum and body or body separately. Conclusions: The omission of the Sydney protocol reduces the detection of H. pylori, atrophic gastritis and intestinal metaplasia by 9.4%, 29.4% and 27.7% respectively. The protocol must be implemented systematically in every gastrointestinal endoscopy center.
RESUMO
Helicobacter pylori es un microrganismo que se considera que afecta al 50% de la población. Se realizó un estudio con diseño no experimental, correlacional y transversal, con el objetivo de determinar la asociación de los resultados de pruebas diagnósticas de infección por H. pylori a través de biopsia obtenida por endoscopía superior y prueba de antígeno de la superficie en mues-tras de heces en 100 pacientes atendidos en el Servicio de Gastroenterología del Centro Clínico Quirúrgico Ambulatorio (Hospital del Día) Efrén Jurado López del Instituto Ecuatoriano de Seguridad Social (IESS), en la ciudad de Guayaquil, Ecuador, durante 2019. La media de la edad en la muestra de estudio fue 37,5 años, con un predominio del género femenino (78%). El 65% de las pruebas de antígeno para la detección de H. pylori en heces resultaron negativas. Los repor-tes de las pruebas de antígeno en heces e histopatología permitieron apreciar diferencias entre estos, pero con predominio de las coincidencias en los diagnósticos positivos. Existió una asocia-ción estadísticamente significativa entre las lesiones inflamatorias de la mucosa gástrica producto de la gastritis crónica atrófica y la infección por H. pylori. Los resultados de las dos pruebas diag-nósticas tuvieron una correlación lineal positiva y débil con significación estadística.
Helicobacter pylori is a microorganism that affects 50% of the population worldwide. A study with a non-experimental, correlational, and cross-sectional design was carried out in order to determine the association of the results of diagnostic tests for H. pylori infection through biopsy obtained by upper endoscopy and surface antigen test in samples of feces in 100 patients. These ones were treated at the Gastroenterology Service of the Ambulatory Surgical Clinic Center (Hospital del Día) Efrén Jurado López of the Ecuadorian Institute of Social Security (IESS), in the city of Guayaquil, Ecuador, during 2019. The mean age in the study sample was 37.5 years old, with a predominance of the female gender (78%). 65% of stool antigen tests for H. pyloriwere negative. The reports of the stool antigen test and histopathology allowed to appreciate differences between them, but with a predominance of the coincidences in the positive diagno-ses. There was a statistically significant association between the inflammatory lesions of the gastric mucosa because of chronic atrophic gastritis and the infection by H. pylori. The results of the two diagnostic tests had a positive and weak linear correlation with statistical significance

Traditional Chinese Medicine (TCM) alone or combined with western medicine has obvious clinical therapeutic effects on chronic atrophic gastritis, especially in improving symptoms and reversing lesions, based on the basic pathogenesis of chronic atrophic gastritis with deficiency in origin and excess in superficiality. The therapeutic methods include invigorating spleen, activating blood circulation and detoxification. The main mechanism is to inhibit cell proliferation, induce apoptosis, change the micro-environment, reduce the degree of inflammation, repair damaged mucosa and improve immune function.
RESUMO
Introducción: La gastritis eosinofílica es una enfermedad infrecuente caracterizada por la presencia de eosinofilia hística, que afecta las diferentes capas de la pared intestinal. Este tipo de gastritis se caracteriza por una infiltración eosinofílica intensa que puede afectar solo la mucosa gástrica o todas sus capas hasta la serosa. La presentación clínica difiere de la posición y la extensión de la infiltración del eosinófilo, así como también su profundidad a través de la pared del intestino. Objetivo: Presentar el caso de un paciente diagnosticado y tratado como una gastritis eosinofílica. Caso clínico: Paciente masculino, raza blanca, de 47 años de edad, que acudió al Servicio de Gastroenterología del Hospital Universitario Manuel Ascunce Domenech, de la provincia Camagüey; en octubre de 2019. Refirió que durante los dos últimos meses había consultado en atención primaria de forma esporádica por molestias epigástricas, estos episodios cedían con pautas cortas de antiácidos. Los síntomas comenzaron agudizarse y se hicieron más resistentes al tratamiento, apareciendo náuseas, vómitos y pérdida de peso marcada. Se decidió comenzar la realización de estudios analíticos al paciente. Conclusiones: El resultado del estudio histológico fue infiltrado inflamatorio crónico severo con presencia de eosinófilos más del 50 % que se extiende a todas las capas con epitelio glandular reactivo, concluyó como una gastritis eosinofílica.
Introduction: Eosinophilic gastroenteritis is a rare disease characterized by the presence of tissue eosinophilia, which affects the different layers of the intestinal wall.This type of gastritis is characterized by an intense eosinophilic infiltration that can affect only the gastric mucosa or all its layers up to the serosa. The clinical presentation differs on the position and extent of the eosinophil infiltration, as well as its depth through the bowel wall. Objective: To present the case of a patient diagnosed and treated as eosinophilic gastritis. Case report: A 47-year-old white male patient from Camagüey province, who attends the Gastroenterology Service of the Manuel Ascunce Domenech University Hospital, Camagüey province; in October 2019. He reported that during the last two months he had consulted primary care sporadically due to epigastric discomfort, these episodes subsided with short courses of antacids. The symptoms began to worsen and became more resistant to treatment, with nausea, vomiting and marked weight loss appearing. It was decided to start performing analytical studies on the patient. Conclusions: The result of the histological study was a severe chronic inflammatory infiltrate with the presence of eosinophils more than 50% that extends to all layers with reactive glandular epithelium, concluding it as eosinophilic gastritis.
RESUMO
Objective:To explore an ideal method for establishing a mouse model of chronic atrophic gastritis (CAG).Methods:CAG mouse models were established with five different modeling methods ( N-methyl- N′-nitro- N-nitrosoguanide (MNNG), sodium salicylate, sodium deoxycholate, Helicobacter pylori infection, and combinations of them) in BALB/c and C57 mice. The effect of each modeling method was evaluated by histological observation of gastric mucosa, plasma biochemical parameters, inflammatory response score, and the expression of anti-inflammatory factors. Results:The results of histological observation of gastric mucosa showed that all of the 5 methods could successfully establish CAG mouse models. In BALB/c mice, compared with the healthy control group, significant features of CAG accompanied with intestinal metaplasia was found in the model group established by combination of MNNG-free drinking, 2% sodium salicylate and 20 mmol sodium deoxycholate. From the results of serological detection, compared with the normal control group, the mRNA expression levels of related anti-inflammatory factors interleukin-2, interleukin-10, interleukin-13 and growth differentiation factor-15 of each model group decreased, which indicated that the mice of each CAG model group had different degrees of inflammation. The results of plasma biochemical parameters indicated that plasma gastrin of each group decreased and the ratio of pepsinogen Ⅰ and pepsinogen Ⅱ significantly dropped. The above results demonstrated that in BLAB/c mice, MNNG-free drinking, 2% sodium salicylate and 20 mmol sodium deoxycholate was better than other four modeling methods. For C57 mice, it was also found that simple chemical drug mutagenesis and Helicobacter pylori replication method both could successfully establish CAG models. No matter from pathological observation, relative expression of anti-inflammatory factors and analysis of plasma biochemical parameters, the effects of combination of the two methods was better. Conclusion:The CAG mouse model established by MNNG-free drinking, 2% sodium salicylate and 20 mmol sodium deoxycholate can provide a certain reference for the establishment and application of mouse model in CAG experiments in the future for pharmacological research.
RESUMO
Objective:To evaluate the clinical efficacy of Wanfu-Qutong Decoction combined with esomeprazole in the treatment of chronic atrophic gastritis (CAG). Methods:A total of 106 CAG patients who met the inclusion criteria from June 2017 to June 2019 were randomly divided into two groups with 53 in each group. The control group took esomeprazole magnesium enteric coated tablets, and the observation group took Wanfu-Qutong Decoction on the basis of the control group. Both groups were treated continuously for 3 months. TCM syndrome score was performed before and after treatment, and the new Sydney system intuitive simulation score method was used to score the histopathology of gastric mucosa. The levels of gastrin 17 (G-17), pepsinogen (PGⅠ , PGⅡ) and the PG Ⅰ/Ⅱ were measured by ELISA. Results:The total effective rate was 96.2% (51/53) in the observation group and 79.2% (42/53) in the control group. There was significant difference between the two groups ( χ2=7.414, P<0.01). After treatment, the scores of epigastric pain, fullness, liking temperature and pressing, vomiting clear water, eating less and staying foolish, and limb burnout in the observation group were significantly lower than those in the control group ( t values were 2.788, 3.632, 3.816, 1.590, 2.183, 2.103, respectively, all Ps<0.05), and the scores of chronic inflammatory reaction, inflammatory activity, atrophy degree, dysplasia and intestinal metaplasia in the mucosa were significantly lower than those in the control group ( t values were 2.983, 2.106, 2.106, 3.773, 1.922, 3.095, respectively, all Ps<0.05). After treatment, the serum G-17 [(14.47 ± 3.06) pmol/L vs. (10.67 ± 2.47) pmol/L, t=10.510] and PG Ⅰ [(130.31 ± 14.79) μg/L vs. (102.36 ± 12.63) μg/L, t=8.178] and PG Ⅰ/Ⅱ [(10.45 ± 0.48) vs. (9.17 ± 0.72), t=2.104] in the observation group were significantly higher than those in the control group ( P<0.01 or P<0.05). Conclusion:Wanfu-Qutong Decoction combined with esomeprazole tablets can effectively improve the clinical symptoms of CAG patients, regulate the levels of G-17, PG Ⅰ , PG Ⅱ and PGⅠ/Ⅱ, and promote the repair of gastric mucosa.

TCM symptom scores were performed before and after treatment, the levels of IL-6, IL-8 and TNF-α were detected by ELISA, and the levels of serum motilin (MLT), gastrin-17 (G17) and gastrin (gas) were detected by radioimmunoassay, the safety of medication was observed and the clinical efficacy was evaluated. Results:The total effective rate was 93.9% (46/49) in the observation group and 71.4% (35/49) in the control group. There was significant difference between the two groups ( χ2=8.611, P=0.043). After treatment, the scores of epigastric burning, fullness in stomach, dull appetite, dry mouth and bitter mouth, shortness of breath and unwillingness to speak, general lassitude, pale tongue, small and weak pulse in the observation group were significantly lower than those in the control group ( t=12.061, 7.331, 6.869, 5.975, 5.208, 10.567, 8.738, 8.631, respectively, all Ps<0.01), and the levels of serum IL-6, IL-8 and TNF-α were significantly lower than those in the control group ( t=8.573,13.423,12.099, respectively, all Ps <0.01). After treatment, the level of serum MLT (154.52 ± 26.25 ng/L vs. 180.26 ± 28.13 ng/L, t=4.488) in the observation group was lower than that of the control group ( P<0.01); the levels of G17 (14.28 ± 1.75 pmol/L vs. 10.28 ± 1.06 pmol/L, t=-7.966) and GAS (24.73 ± 3.42 ng/L vs. 19.02 ± 3.38 ng/L, t=-13.115) in the observation group were significantly higher than those in the control group ( t=-7.966 and -13.115, respectively, all Ps<0.01). During the treatment, the incidence of adverse reactions was 8.16% (4/49) in the observation group and 6.12% (3/49) in the control group, and there was no significant difference between the two groups ( χ2=0.152, P=0.695). Conclusion:Shaoyao-Bawei Decoction combined with moxibustion can alleviate the clinical symptoms of CAG patients with spleen stomach weakness syndrome, regulate the level of inflammatory cytokines, promote the recovery of gastrointestinal function and improve the clinical curative effect.
RESUMO
RESUMEN La metaplasia intestinal gástrica y la gastritis atrófica son condiciones precancerosas conocidas (CPCs) del estómago, lo que significa que los pacientes con CPCs están en riesgo de desarrollar cáncer gástrico y, por lo tanto, el diagnóstico y la categorización de riesgo para estos pacientes es un tema relevante. El objetivo de esta revisión es proporcionar una actualización sobre el problema, el diagnóstico y el manejo de las CPCs con énfasis en el papel de la detección endoscópica adecuada.
ABSTRACT Gastric intestinal metaplasia and atrophic gastritis are a known precancerous condition (PCC) of the stomach, meaning that patients with PCC are at risk for gastric cancer and so, diagnosis and risk categorization for these patients is relevant. The aim of this review is to provide an update regarding the problem, diagnosis, and management of PCCs with an emphasis on the role of appropriate endoscopic detection.
