RESUMEN

AIM:To explore the molecular mechanism of Tiaopi Chengqi decoction (TpCqD) improving hyperthermia and high-protein food-induced hyperphagia mice based on transcriptomics. METHODS:C57 mice were randomly divided into a control group, model group, low-dose TpCqD group, high-dose TpCqD group, and domperidone group. The general condition of the experimental mice was observed and the average food intake was counted, and the rate of gastric emptying and intestinal propulsion was determined for each group of mice. H&E staining was used to observe pathological changes in gastric tissue. PAS staining was used to observe glycogen changes in gastric tissue. Pepsin activity was determined by colorimetry. pH value of gastric contents was measured by acid-base titration. Transcriptome sequencing was used to analyze the differential genes in gastric tissue, a volcano map and a cluster heat map were made for the differential genes, and KEGG was used to analyze the signal pathway enrichment of the differential genes. RT-qPCR verified the differential genes obtained by screening. RESULTS:After treatment with TpCqD, the body weight and average food intake of mice with food accumulation increased (P<0.05), and the intestinal propulsion rate and gastric emptying speed of mice with food accumulation accelerated (P<0.05). TpCqD could protect gastric tissue structure and glycogen degradation, increase pepsin activity (P<0.05), and reduce gastric content pH (P<0.05). Transcriptome results showed that TpCqD could regulate the expression of Acox2 and cilp2, regulate fat digestion and absorption, protein digestion and absorption, and pancreatic secretion signals. RT-qPCR showed that compare with model group, TpCqD up-regulated Acox2 (P<0.05) and down-regulated the mRNA level of cilp2 (P<0.05). CONCLUSION:TpCqD ameliorated digestive dysfunction in mice with high-calorie and high-protein diets leading to food accumulation involving the regulation of the fat and sugar metabolism genes Acox2 and cilp2, and pancreatic secretory signaling.

RESUMEN

RESUMEN Introducción: Sarcina ventriculi es un coco Gram (+), anaerobio, inmóvil, con un metabolismo fermentativo de carbohidratos, que sobrevive y crece sin problemas en ambientes con pH ácido. Es un agente etiológico conocido en patología veterinaria, sin embargo, su rol patogénico en humanos es controversial. En años recientes, se ha reportado en humanos, cada vez con mayor frecuencia el hallazgo de éste microorganismo en diferentes lugares anatómicos, a predominio del tubo digestivo superior, principalmente en el estómago, en pacientes con dispepsia y/o retardo en vaciamiento gástrico, algunos de éstos casos con evolución grave, incluso mortal. Caso clínico: Reportamos el caso de una paciente con sintomatología dispéptica, en cuya biopsia gástrica se identifica Sarcina ventriculi y cuyo tratamiento farmacológico dirigido terminó con las molestias descritas. A lo mejor de nuestro conocimiento, éste es el primer caso reportado en Perú.


ABSTRACT Introduction: Sarcina ventriculi is a Gram (+), anaerobic, non-motile cocci, with a fermentative carbohydrate metabolism, that survives and grows without problems in environments with acidic pH. It is a known etiological agent in veterinary pathology, however its pathogenic role in humans is controversial. In recent years, the finding of this microorganism in different anatomical places has been reported in humans with increasing frequency, predominantly in the upper digestive tract, mainly in the stomach, in patients with dyspepsia and/or delayed gastric emptying, some of these cases with serious evolution, even fatal. Clinical case: we report the case of a patient with dyspeptic symptoms, whose gastric biopsy identified Sarcina ventriculi and whose targeted pharmacological treatment ended the discomfort described. To the best of our knowledge, this is the first case reported in Perú.

RESUMEN

Los métodos de inteligencia artificial utilizando herramientas de aprendizaje no supervisado pueden apoyar la resolución de problemas al establecer patrones de agrupación o clasificación no identificados, que permiten tipificar subgrupos para manejos más individualizados. Existen pocos estudios que permiten conocer la influencia de síntomas digestivos y extradigestivos en la tipificación dispepsia funcional; esta investigación realizó un análisis de aprendizaje no supervisado por conglomerados basándose en dichos síntomas, para discriminar subtipos de dispepsia y comparar con una de las clasificaciones actualmente más aceptadas. Se realizó un análisis exploratorio de conglomerados en adultos con dispepsia funcional según síntomas digestivos, extradigestivos y emocionales. Se conformaron patrones de agrupación de tal manera que dentro de cada grupo existiera homogeneidad en cuanto a los valores adoptados por cada variable. El método de análisis de conglomerados fue bietápico y los resultados del patrón de clasificación se compararon con una de las clasificaciones más aceptadas de dispepsia funcional. De 184 casos, 157 cumplieron con criterios de inclusión. El análisis de conglomerados excluyó 34 casos no clasificables. Los pacientes con dispepsia de tipo 1 (conglomerado uno), presentaron mejoría al tratamiento en el 100% de los casos, solo una minoría presentaron síntomas depresivos. Los pacientes con dispepsia de tipo 2 (conglomerado dos) presentaron una mayor probabilidad de falla al tratamiento con inhibidor de bomba de protones, padecieron con mayor frecuencia trastornos de sueño, ansiedad, depresión, fibromialgia, limitaciones físicas o dolor crónico de naturaleza no digestiva. Esta clasificación de dispepsia por análisis de clúster establece una visión más holística de la dispepsia en la cual características extradigestivas, síntomas afectivos, presencia o no de trastornos de sueño y de dolor crónico permiten discriminar el comportamiento y respuesta al manejo de primera línea.


Artificial intelligence methods using unsupervised learning tools can support problem solving by establishing unidentified grouping or classification patterns that allow typing subgroups for more individualized management. There are few studies that allow us to know the influence of digestive and extra-digestive symptoms in the classification of functional dyspepsia. This research carried out a cluster unsupervised learning analysis based on these symptoms to discriminate subtypes of dyspepsia and compare with one of the currently most accepted classifications. An exploratory cluster analysis was carried out in adults with functional dyspepsia according to digestive, extra-digestive and emotional symptoms. Grouping patterns were formed in such a way that within each group there was homogeneity in terms of the values adopted by each variable. The cluster analysis method was two-stage and the results of the classification pattern were compared with one of the most accepted classifications of functional dyspepsia. Of 184 cases, 157 met the inclusion criteria. The cluster analysis excluded 34 unclassifiable cases. Patients with type 1 dyspepsia (cluster one) presented improvement after treatment in 100% of cases, only a minority presented depressive symptoms. Patients with type 2 dyspepsia (cluster two) presented a higher probability of failure to treatment with proton pump inhibitor, suffered more frequently from sleep disorders, anxiety, depression, fibromyalgia, physical limitations or chronic pain of a non-digestive nature. This classification of dyspepsia by cluster analysis establishes a more holistic vision of dyspepsia in which extradigestive characteristics, affective symptoms, presence or absence of sleep disorders and chronic pain allow discriminating behavior and response to first-line management.

RESUMEN

We present the case of a patient suffering from a mixed-type functional dyspepsia who markedly reduced his diet to improve his symptoms leading him to malnourishment and a subsequent Wilkie's and Nutcracker's syndromes which exacerbated his pain. Our aim by presenting this case is to raise awareness as to what extent a so-called functional dyspepsia can evolve and of the possible overlap with these two entities in case of severe malnutrition.


Presentamos el caso de un paciente diagnosticado de dispepsia funcional de tipo mixto, el cual redujo marcadamente su dieta para mejorar sus síntomas, llevándolo a una desnutrición y a un posterior síndrome de Wilkie y del Cascanueces que agudizó su dolor. Nuestro objetivo con la presentación de este caso es concienciar de hasta qué punto puede evolucionar una denominada dispepsia funcional y del posible solapamiento de estas dos entidades en caso de desnutrición severa.

RESUMEN

Objective:To explore the clinical observation of Xiaozhang Plaster for external use in the treatment of postprandial discomfort syndrome of qi stagnation functional dyspepsia.Methods:Randomized controlled trial. From January 2019 to January 2022, 128 patients with postprandial discomfort syndrome of functional dyspepsia of qi stagnation type in our hospital were selected and divided into two groups by random number table, with 64 cases in each group. Both groups were orally treated with mosapride citrate tablets. On this basis, the treatment group was combined with external use of Xiaozhang Plaster, and the control group was combined with placebo patch. Both groups were treated for 2 weeks. Traditional Chinese Medicine syndrome score, symptom severity and attack frequency score were performed before and after treatment. The quality of life of the patients was assessed with SF-36 Short-form health survey-36 (SF-36), anxiety and depression were assessed with Hospital Anxiety and Depression Scale (HADS), and the growth hormone releasing peptide (Ghrelin), calcitonin gene-related peptide (CGRP) The levels of gastrin 17 (G-17), pepsinogen I (PG I) and pepsinogen Ⅱ (PG Ⅱ) levels were observed by ELISA, and clinical efficacy was evaluated.Results:The total effective rate was 96.88% (62/64) in the treatment group and 81.25% (52/64) in the control group. The difference between the two groups was statistically significant ( χ2=8.02, P<0.05). After treatment, the score and total score of epigastric distension, epigastric distension and pain, fullness of both flanks, loss of appetite in the treatment group were significantly lower than those in the control group ( t=38.43, 32.39, 38.43, 32.87, 33.74, P<0.01), the score of symptom severity and attack frequency were significantly lower than those in the control group ( t=61.42, 33.46, P<0.01), and the score of SF-36 was significantly higher than that in the control group ( t=8.26, P<0.01); The score of HADS was significantly lower than that of the control group ( t=38.06, P<0.01). After treatment, the levels of CGRP and G-17 in the treatment group were significantly lower than those in the control group ( t values were 6.22, 29.51, P<0.01), the level of Ghrelin, and the levels of PG Ⅰ, PG Ⅱ were significantly higher than those in the control group ( t=23.85, 13.26, 19.53, P<0.01). Conclusion:On the basis of basic drug treatment, the application of Xiaozhang Plaster for external use to intervene patients with postprandial discomfort syndrome of qi stagnation functional dyspepsia can improve the quality of life, gastrointestinal hormones, anxiety and depression symptoms, and the effect is remarkable.

RESUMEN

The incidence rate of functional dyspepsia (FD) is high. Helicobacter pylori (Hp) infection is one of the main causes of FD. Eradication of Hp is the current first-line treatment. However, the actual efficacy of eradicating Hp with the triple/quadruple therapy of Western medicine alone is not satisfactory for Hp-positive FD patients. TCM-assisted triple/quadruple therapy for Hp positive FD has a good efficacy, which has the effects of anti-Hp, regulating gastrointestinal hormones and gastric electrical parameters, and improving gastrointestinal motility. It can improve the eradication rate of Hp, effectively alleviate the clinical symptoms of patients, and improve the pathological conditions such as abnormal gastrointestinal secretion, abnormal motility, and abnormal sensation. The diagnostic and treatment idea of integrated TCM and Western medicine is worthy of summary and promotion.

RESUMEN

ObjectiveTo explore the intervention mechanism of Xiangsha Liujunzi Tang in rats with functional dyspepsia (FD) based on the Ras homolog gene family member A (RhoA)/Rho-associated coiled-coil containing protein kinase 2 (ROCK2)/Myosin phosphatase target Subunit 1 (MYPT1) pathway. MethodSixty male SD suckling rats in SPF grades were randomly divided into blank group (n=10) and model group (n=50). The comprehensive modeling method (gavage administration of iodoacetamide+exhaustion of swimming+disturbance of hunger and satiety) was used to replicate the rat model of FD. After successful replication of the model, the rats in the model group were randomly divided into model group, mosapride group, and high, middle, and low-dose Xiangsha Liujunzi Tang groups, with 10 rats in each group. Rats in the blank group and model group were given 10 mL kg-1·d-1 normal saline, those in the mosapride group were given 1.35 mg·kg-1·d-1 mosapride, and those in the high, middle, and low-dose Xiangsha Liujunzi Tang groups were given 12, 6, and 3 g·kg-1·d-1 Xiangsha Liujunzi Tang, respectively. The intervention lasted 14 days. The general living conditions of rats were observed before and after modeling and administration, and the 3-hour food intake and body mass of rats were measured. After intervention, the intestinal propulsion rate of rats was measured, and the pathological changes in the gastric tissue were observed by hematoxylin-eosin (HE) staining. The content of choline acetyl transferase (ChAT) and vasoactive intestinal peptide (VIP) in the medulla oblongata and gastric tissue homogenate was determined by enzyme-linked immunosorbent assay (ELISA), the distribution of adenosine triphosphate (ATP) enzyme in gastric antrum smooth muscle was observed by frozen section staining, and the protein expression levels of RhoA, ROCK2, and phosphorylated-myosin phosphatase target subunit 1 (p-MYPT1) in the gastric tissue were detected by Western blot. ResultCompared with the blank group, the model group had withered hair, lazy movement, slow action, poor general living condition, lower 3-hour food intake, body mass, and lower intestinal propulsion rate (P<0.05), whereas no obvious abnormality in gastric histopathology. In the model group, the content of ChAT in the medulla oblongata and gastric tissue decreased, the content of VIP in gastric tissue increased, the distribution of ATP enzyme in gastric antrum smooth muscle decreased significantly, and the protein expression levels of RhoA, ROCK2, and p-MYPT1 in the gastric tissue decreased significantly (P<0.05). As compared with the model group, the general living condition of rats in each intervention group was significantly improved, and the 3-hour food intake, body mass, and intestinal propulsion rate were significantly increased (P<0.05). There was no significant difference in gastric pathology in the intervention groups. The content of ChAT in the medulla oblongata and gastric tissue increased significantly, the content of VIP in the gastric tissue decreased, the distribution of ATP enzyme in gastric antrum smooth muscle increased significantly, and the protein expression levels of RhoA, ROCK2, and p-MYPT1 in the gastric tissue increased significantly (P<0.05). The intervention effect of Xiangsha Liujunzi Tang group on the above indexes was dose-dependent. ConclusionXiangsha Liujunzi Tang can effectively improve the general living condition and gastric motility of rats with FD, and its specific mechanism may be related to the activation of the RhoA/ROCK2/MYPT1 pathway in the gastric tissue to regulate smooth muscle relaxation and contraction and promote gastric motility.

RESUMEN

This study was conducted to evaluate the efficacy and safety of Simotang Oral Liquid in the treatment of functional dyspepsia in adults. "Simotang Oral Liquid" "Simotang" "Si Mo Tang" "Si Mo Tang Oral Liquid" were used for retrieval of the relevant papers from CNKI, Wanfang, VIP, SinoMed, PubMed, Cochrane Library, Springer Link, and Web of Science from database inception to June 2021. Randomized controlled trial(RCT) of Simotang Oral Liquid in the treatment of functional dyspepsia in adults was screened out for Meta-analysis which was conducted in RevMan 5.3. A total of 16 RCTs were included. Meta-analysis showed that compared with the control group, Simotang Oral Liquid increased the total response rate and lowered the traditional Chinese medicine syndrome scores, serum cholecystokinin(CCK), serum nitric oxide(NO), and incidence of adverse reactions. However, the serum substance P(SP) had no statistical difference between the two groups. Simotang Oral Liquid is effective and safe in the treatment of functional dyspepsia in adults. However, this study has evidence and limitations, so the conclusions need to be further verified by large sample and multicenter clinical studies.

RESUMEN

OBJECTIVES@#To observe the effects of electroacupuncture (EA) at "Neiguan" (PC 6) and "Zusanli"(ST 36) on the gastric emptying rate, the level of serotonin (5-HT) and the protein expression of motilin (MTL), ghrelin, substance P (SP) and vasoactive intestinal peptide (VIP) in the antral tissue of the rats with functional dyspepsia (FD) and explore the effect mechanism of EA in treatment of FD.@*METHODS@#A total of 21 SPF male SD rat pups were randomly divided into a normal group, a model group and an EA group, with 7 rats in each group. In the model group and the EA group, FD model was prepared by the gavage with 0.1% sucrose iodoacetamide solution combined with the modified small platform method. After the successful modeling, EA was applied to "Neiguan" (PC 6) and "Zusanli"(ST 36) in the rats of the EA group, with disperse-dense wave, 20 Hz/100 Hz in frequency, stimulated for 30 min, once daily, for 7 days consecutively. Before and after intervention, the general condition of the rats was observed in each group. After the completion of intervention, the gastric emptying rate was measured, the morphological changes of gastric antral tissue were observed using HE staining, the level of 5-HT was detected with ELISA method, and the protein expression of MTL, ghrelin, SP, and VIP was determined with Western blot method in the antral tissue of rats.@*RESULTS@#In the normal group, the rats were in a good mental state, with lustrous fur, flexible movement and the increase of food intake and body mass. In the model group, the rats were poor in mental state, lack of lustre in fur, preference for the body curled up, reduced activity and response; and a part of rats had loose stool, obviously enlarged gastric body and gastric food retention. In the EA group, the general condition of rats, e.g. the mental state, food intake and activity, were improved, the gastric body got smaller obviously and the gastric food retention was reduced when compared with the model group. The antral structure was intact, the glands were rich and no injury of the gastric mucosa was found, e.g. inflammatory reaction and edema in the rats of each group. Compared with the normal group, the gastric emptying rate was decreased (P<0.01), 5-HT level was increased (P<0.01), the protein expression of MTL and ghrelin was reduced (P<0.01) and that of VIP was elevated (P<0.01) in the rats of the model group. The gastric emptying rate was increased (P<0.01), 5-HT level was decreased (P<0.01), and the protein expression of MTL and ghrelin was elevated (P<0.05, P<0.01) in the rats of the EA group when compared with those in the model group.@*CONCLUSIONS@#Electroacupuncture at "Neiguan" (PC 6) and "Zusanli"(ST 36) may effectively relieve gastric dysfunction, strengthen gastric motility and promote gastric emptying so as to alleviate the symptoms of dyspepsia in FD rats, and its mechanism may be related to the regulation of gastrointestinal hormones in the antral tissue.

RESUMEN

ObjectiveTo study the possible mechanism of Chaihu Shugan Powder (柴胡疏肝散, CSP) in the treatment of functional dyspepsia (FD). MethodsTwenty-four SD rats were randomly divided into a normal group, a model group, a CSP group and a probiotic group, with six rats in each group.The tail-clamping provocation method was used in all groups except for the normal group to replicate the FD rat model. Simultaneously, the normal group and the model group were given 10 ml/(kg·d) of saline by gavage, while the CSP group and the probiotic group were given 9.6 g/(kg·d) of CSP aqueous decoction and 0.945 g/(kg·d) of probiotic aqueous solution by gavage, respectively, twice daily for four weeks. After four weeks, the gastric emptying and small intestinal propulsion rates were detected in each group of rats. Hematoxylin-eosin (HE) staining was used to observe the histopathological changes in the gastric sinusoids and duodenum of the rats. The changes in the intestinal flora were analyzed by 16s rDNA high-throughput gene sequencing, and the expressions of the duodenal zona occludin 1 (ZO-1) and Occludin were detected by immunohistochemistry and western blotting. Pearson correlation analysis was performed on intestinal flora and ZO-1 and Occludin protein expression. ResultsThe gastric antrum tissue structure was clear in all groups, and the gland structure was regular, with smooth gastric tissue mucosa and no pathological changes such as erosion and ulcer. Compared to those in the normal group, the intestinal villi in the duodenal tissue in the model group were significantly reduced or atrophied, and the goblet cells were arranged in disorder, with eosinophilic infiltration; the gastric emptying rate and small intestinal propulsion rate, as well as ZO-1 and Occludin protein expression in duodenal tissue significantly decreased (P<0.01). Compared to those in the model group, the duodenal tissue structure was clear, and the length intestinal villi was longer, with goblet cells neatly arranged in the CSP group and the probiotic group; no obvious eosinophil infiltration was found, and the gastric emptying rate and small intestinal propulsion rate as well as ZO-1 and Occludin protein expression significantly increased in the CSP group; a small amount of eosinophil infiltration was found, and the gastric emptying rate and Occludin protein expression significantly increased in the probiotic group (P<0.05 or P<0.01). Beta diversity analysis of intestinal flora showed that the overall structure of intestinal flora in the model group changed significantly compared to that in the normal group (P<0.01). The overall structure of the intestinal flora in the CSP group and the probiotic group was closer to the normal group than the model group. Species composition analysis showed that the relative abundance of the Firmicutes decreased, while the relative abundance of the Bacteroidetes and norank_f_Muribaculaceae increased, and the Bacteroidetes/Firmicutes value increased in the model group than those in the normal group (P<0.05 or P<0.01). Compared to those in the model group, the relative abundance of the Firmicutes increased, while the relative abundance of the Bacteroidetes and norank_f_Muribaculaceae, as well as the Bacteroidetes/Firmicutes value decreased in the CSP group and the probiotic group (P<0.05 or P<0.01). There was no statistically significant difference in each indicator between the probiotic group and the CSP group (P>0.05). Pearson correlation analysis showed that at the phylum level, Firmicutes was positively correlated with ZO-1 (r=0.610, P=0.016) and Occludin (r=0.694, P=0.004) protein expression. Bacteroidetes was negatively correlated with ZO-1 (r=-0.557, P=0.031) and Occludin (r=-0.662, P=0.007) protein expression. At the genus level, norank_f_Muribaculaceae was negatively correlated with ZO-1 (r=-0.727, P=0.002) and Occludin (r=-0.760,P=0.001) protein expression. ConclusionCSP can restore the structure of intestinal flora, regulate the abundance levels of Firmicutes, Bacteroidetes and norank_f_Muribaculaceae, up-regulate ZO-1 and Occludin proteins, and thus repairing the duodenal mucosal barrier, and playing a therapeutic role in FD rats.

RESUMEN

Dyspepsia is the one of the most common clinical manifestations of digestive system diseases and has various and complex causes, among which pancreatic tumor is a relatively uncommon cause and is easily neglected in clinical practice. The dual factors of tumor and dyspepsia may cause a significant reduction in the quality of life of patients. At present, there is still a lack of standardized diagnosis and treatment strategies for dyspepsia associated with pancreatic tumors, and this article reviews the diagnosis and treatment of this disease.

RESUMEN

Dyspepsia is a common group of clinical symptoms and can be classified into organic and functional dyspepsia. Patients with chronic pancreatitis (CP) often have the symptoms of dyspepsia such as fatty diarrhea, abdominal distention, and abdominal pain, and most patients have pancreatic exocrine insufficiency (PEI), which belongs to organic dyspepsia. In clinical practice, the diagnosis of PEI and dyspepsia requires a comprehensive assessment of clinical manifestations, nutritional status, and pancreatic exocrine function, and an individualized treatment regimen should be developed based on such factors. However, some patients with normal exocrine function may have the symptoms of dyspepsia, and the diagnosis and treatment of such patients are still difficulties in clinical practice. This article reviews the advances in the diagnosis and treatment of dyspepsia in CP patients.

RESUMEN

Various pancreatic diseases can cause dyspepsia due to pancreatic exocrine insufficiency (PEI) caused by pancreatic parenchymal injury and/or pancreatic duct obstruction, which further leads to impaired digestive function and a series of severe clinical outcomes such as malnutrition, weight loss, and shortened survival time. Therefore, pancreatic disease-related dyspepsia should be taken seriously in clinical practice to improve its diagnosis and treatment rates, so as to improve the quality of life of patients with pancreatic diseases and prolong overall survival time.

Objective@#To evaluate the methodological quality of papers that performed meta-analyzed and systematically reviewed acupoint selections for the treatment of functional dyspepsia (FD) and to identify the ideal acupoint combinations for FD.@*Methods@#Chinese databases including China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (VIP), China Biology Medicine (CBM), and Wanfang Database, as well as English databases including PubMed, Embase, and Cochrane Library were searched to retrieve papers about meta-analysis and systematic literature reviews on acupuncture for FD. The time span for the paper retrieval was set from the foundation of the databases to April 30, 2022. The Veritas scores of the papers based on their publication year, study type, Assessment of Multiple Systematic Reviews 2 (AMSTAR2), Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), heterogeneity, and publication bias were rated to assess the methodological quality of the included studies. Then, randomized controlled trials (RCTs) were extracted from those meta-analysis papers or systematic literature reviews for analyzing acupoints frequency, meridian frequency, and association rules with the use of R software (V 4.3.1).@*Results@#Eight meta-analysis papers were included in the study after screening. The mean Veritas scores of the papers based on publication year, type of study, AMSTAR2, PRISMA, heterogeneity, and publication bias were 4.50, 8.00, 4.63, 4.63, 4.50, and 6.13, respectively. The analysis of the scores revealed insufficiencies in the reviews pertaining to the methodology, comprehension of the research strategy, detailed list of excluded studies, sources of funding, assessment of potential bias risks impact on meta-analysis results in each study, explanation of heterogeneity, and identification of potential conflicts of interest. Furthermore, a total of 85 RCTs were obtained from the eight meta-analysis papers involving 85 acupuncture prescriptions and 67 acupoints for subsequent data mining. The most commonly used meridian was Stomach meridian of Foot-Yangming (ST). Zusanli (ST36), Neiguan (PC6), Zhongwan (CV12), Taichong (LR3), Tianshu (ST25), Gongsun (SP4), Weishu (BL21), Pishu (BL20), Neiting (ST44), and Yinlingquan (SP9) topped the list of frequently selected acupoints. Additionally, a total of 28 association rules were identified, including 10 second-order, 15 third-order, and 3 fourth-order association rules. The top-ranking association rules in each order were “Neiguan (PC6) → Zusanli (ST36)” “Zhongwan (CV12) + Neiguan (PC6) → Zusanli (ST36)” and “Zhongwan (CV12) + Taichong (LR3) + Neiguan (PC6) → Zusanli (ST36)”, respectively.@*Conclusion@#Acupuncture could alleviate the clinical symptoms of FD. However, the quality of methodology applied in the meta-analysis papers on the subject needs to be improved. Through data mining, a combination of Neiguan (PC6), Zusanli (ST36), Zhongwan (CV12), and Taichong (LR3) was identified as an essential acupoint combination for the treatment of FD.

RESUMEN

Functional dyspepsia (FD) is a common and frequently occurring disease in clinic. With the influence of environmental factors, social factors and dietary factors, the incidence rate of FD in the general population is yearly increasing. Traditional Chinese medicine has a long history and far-reaching influence in the treatment of FD. It can prevent and treat FD in the form of multiple-components, targets and channels, with obvious effect and prominent advantages. This article starts with the common syndrome types of FD, and discusses the research progress of single Chinese medicine, effective ingredients and the mechanism of traditional Chinese medicines in treating FD, in order to provide a theoretical basis for the treatment of FD with traditional Chinese medicines.

RESUMEN

OBJECTIVE@#To compare the clinical efficacy of acupuncture with different frequencies in the treatment of patients with functional dyspepsia (FD).@*METHODS@#A total of 90 patients with FD were randomly divided into a 3-time acupuncture treatment per week group (3-A group, 31 cases, 2 cases dropped off), a 1-time acupuncture treatment per week group (1-A group, 30 cases, 2 cases dropped off) and a control group (29 cases, 2 cases dropped off). In the two acupuncture groups, the acupoints were Zhongwan (CV 12) and bilateral Tianshu (ST 25), Neiguan (PC 6), Liangqiu (ST 34), Yanglingquan (GB 34), Zusanli (ST 36) and Taichong (LR 3), stimulated 3 times a week and once a week, respectively; and the treatment was given consecutively for 4 weeks. In the control group, no intervention was adopted, but the compensatory therapy was provided after the end of follow-up. The scores of the symptom index of dyspepsia (SID), self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were compared among the 3 groups before treatment, after 4 weeks of treatment and in 4 and 8 weeks after treatment completion separately. The score of Nepean dyspepsia life quality index (NDLQI) was evaluated before treatment, after 2 and 4 weeks of treatment and in 4 and 8 weeks after treatment completion.@*RESULTS@#After 4 weeks of treatment and in 4 and 8 weeks after treatment completion, the scores of SID, SAS and SDS were all reduced in the 3-A group and the 1-A group when compared with the scores before treatment (P<0.000 1, P<0.05). After 4 weeks of treatment, the scores of SID, SAS and SDS in the two acupuncture groups were lower than those in the control group (P<0.000 1). After 2 and 4 weeks of treatment, the increased values of NDLQI score in the two acupuncture groups were all higher than those in the control group (P<0.05). In 4 and 8 weeks after treatment completion, the scores of SID, SAS and SDS in the 3-A group were lower than those in the 1-A group (P<0.001, P<0.05), and the increased values of NDLQI score in the 3-A group were higher than those in the 1-A group (P<0.000 1).@*CONCLUSION@#Acupuncture given 3 times per week is superior to the treatment given once per week in the aspects of relieving the clinical symptoms, improving the quality of life and regulating the emotional state in patients with FD. This efficacy is persistent for 8 weeks after treatment completion.

RESUMEN

Functional dyspepsia(FD) is a prevalent functional gastrointestinal disease characterized by recurrent and long-lasting symptoms that significantly impact the quality of life of patients. Currently, western medicine treatment has not made breakthrough progress and mainly relies on symptomatic therapies such as gastrointestinal motility agents, acid suppressants, antidepressants/anxiolytics, and psychotherapy. However, these treatments have limitations in terms of insufficient effectiveness and safety. Traditional Chinese medicine(TCM) possesses unique advantages in the treatment of FD. Through literature search in China and abroad, it has been found that the mechanisms of TCM in treating FD is associated with various signaling pathways, and research on these signaling pathways and molecular mechanisms has gradually become a focus. The main signaling pathways include the SCF/c-Kit signaling pathway, 5-HT signaling pathway, CRF signaling pathway, AMPK signaling pathway, TRPV1 signaling pathway, NF-κB signaling pathway, and RhoA/ROCK2/MYPT1 signaling pathway. This series of signaling pathways can promote gastrointestinal motility, alleviate anxiety, accelerate gastric emptying, reduce visceral hypersensitivity, and improve duodenal micro-inflammation in the treatment of FD. This article reviewed the research on TCM's regulation of relevant signaling pathways in the treatment of FD, offering references and support for further targeted TCM research in the treatment of FD.
