ObjectiveTo observe the clinical efficacy of modified Zuojinwan granules in treating reflux esophagitis （RE） and functional dyspepsia （FD） with the same syndrome with disharmony between liver and stomach）. MethodA randomized double-blind placebo-controlled clinical trial was conducted to enroll 144 patients with disharmony between liver and stomach， including 72 patients with RE and 72 patients with FD. These patients were then randomly divided into observation and control groups， with 36 patients in each group. The observation group was given modified Zuojinwan granules orally， and the control group was given placebo granules orally. They both were treated with two packs each time， twice a day， for four weeks. The traditional Chinese medicine （TCM） syndrome scores， cerebrointestinal peptides ［calcitonin gene-associated titanium （CGRP）， vasoactive intestinal peptide （VIP）， 5-hydroxytryptamine （5-HT）， and substance P （SP）］， inflammatory factors ［tumor necrosis factor-α （TNF-α） and interleukin-6 （IL-6）］， common gastrointestinal related hormones ［gastrin （GAS） and motilin （MTL）］， and other indicators in the two groups were compared before and after treatment， and the curative effect of TCM syndromes and the occurrence of adverse reactions were determined. At the same time， the changes in the above indicators and the curative effect of TCM syndromes in the two groups of patients with the same disease were analyzed. ResultAfter treatment， CGRP， VIP， 5-HT， SP， TNF-α， IL-6， GAS， MTL， and TCM syndrome scores in the observation group and control group were significantly improved （P<0.05）. After treatment， the improvement of CGRP， VIP， 5-HT， SP， TNF-α， IL-6， GAS， MTL， and TCM syndrome scores in the observation group was better than that in the control group （P<0.05）. After treatment， CGRP， VIP， 5-HT， SP， TNF-α， IL-6， GAS， MTL， and TCM syndrome scores in both groups of RE patients and FD patients were significantly improved （P<0.05）. After treatment， the improvement of CGRP， VIP， 5-HT， SP， TNF-α， IL-6， GAS， MTL， and TCM syndrome scores in RE patients and FD patients in the observation group were better than that in the control group （P<0.05）. In the observation group and the control group， the incidence of nausea， vomiting， fatigue， dry mouth， and other adverse reactions was lower， and there was no statistical significance. ConclusionModified Zuojinwan granules can effectively improve the TCM syndromes of disharmony between liver and stomach of RE and FD， brain and intestinal peptide， gastrointestinal hormone， and inflammatory factors and provide evidence for the clinical application of TCM theory of "treating different diseases with the same method".

ObjectiveTo analyse the current implementation status of Chinese herbal medicine （CHM） placebo and systematically evaluate the placebo effect in randomised controlled trials （RCTs） of traditional Chinese medicine （TCM） for the treatment of functional dyspepsia （FD）. MethodsA combination of medical subject terms and free words was used to search six databases， including PubMed， EMBASE， Cochrane Library， Web of Science， China National Knowledge Infrastructure， and Wanfang， for RCTs with CHM placebo group for FD published from January 31st， 1994 to September 30th， 2023. The dosage forms， composition， and methodological quality were collected and evaluated. The quality of the included articles was evaluated by Cochrane risk of bias assessment tool， and meta-analysis was performed on the CHM placebo response rate of patients with FD， and subgroup analysis and meta-regression was performed according to diagnostic criteria， efficacy criteria， duration of treatment， type of placebo， whether it contained active ingredient， and whether it evaluated placebo effects. ResultsA total of 34 publications were included involving 5046 participants， of which 2221 FD patients received CHM placebo treatment. Granules were the predominant placebo preparation， accounting for 71% （24/34）； 32.35% （11/34） of the studies added real CHM to the placebo， and only 12 （35%） of the studies described appearance， odour， and taste. The placebo response rate in FD patients in the placebo group was 41% （95% CI： 0.35 to 0.47； P＜0.01， I2 = 87%）； there was significant difference between groups with different diagnostic criteria and different treatment durations （P＜0.05 or P＜0.01）， but there was no significant difference between the different efficacy evaluation criteria， the different placebo preparation， the presence of a low-dose active ingredient， and the presence or absence of placebo assessment （P＞0.05）. ConclusionThere was a significant CHM placebo effect in patients with FD， with granules as the main preparation of placebop. Different diagnostic criteria and different treatment times may affect the response rate of patients， and the addition of low-dose real medicine to the CHM placebos has not been seen to have an effect on the response rate. Clinical investigators have not paid enough attention to placebos， and there is a lack of uniform standards and norms for the preparation and evaluation of CHM placebos.

Chaihu Shugansan composed of Bupleuri Radix， Paeoniae Radix Alba， Chuanxiong Rhizoma， Aurantii Fructus， Citri Reticulatae Pericarpium， Cyperi Rhizoma， and Glycyrrhizae Radix et Rhizoma has the effects of soothing liver， relieving depression， regulating Qi movement， and relieving pain. It is a classic formula for treating gastric distension recommended by doctors of later ages. This article systematically reviews the clinical application and basic experimental progress of Chaihu Shugansan in the treatment of functional dyspepsia. In modern clinical practice， Chaihu Shugansan and its modified formulas are used to treat functional dyspepsia， and they can be applied in combination with other formulas （Si Junzitang， Jinlingzisan， Zhizhuwan， etc.）， western medicine （domperidone tablets， deanxit， Saccharomyces boulardii， etc.）， traditional Chinese medicine （TCM） acupuncture and other therapies. The results of clinical studies have shown that Chaihu Shugansan and its modified formulas can significantly reduce the Hamilton depression scale （HAMD） score， Hamilton anxiety scale （HAMA） score， and TCM syndrome score， ameliorate the symptoms， improve the quality of life， and decrease the recurrence rate. The experimental pharmacological studies have demonstrated that Chaihu Shugansan can inhibit the autophagy of Cajal interstitial cells， regulate the endoplasmic reticulum stress signaling pathway， and modulate the brain-gut peptide level to improve the gastrointestinal motility. Chaihu Shugansan can inhibit the expression of 5-hydroxytryptamine in the colon tissue and reduce the abdominal withdrawal reflex （AWR） score to improve visceral hypersensitivity. Furthermore， Chaihu Shugansan can lower the levels of pro-inflammatory cytokines such as interleukin-6 and tumor necrosis factor-α to repair duodenal mucosal inflammation. In addition， it can regulate intestinal flora to maintain intestinal flora balance. The main active ingredients such as saikosaponin， paeoniflorin， hesperidin， and naringin in Chaihu Shugansan can exert anti-inflammatory， antioxidant， and antimicrobial effects.

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.

Objective:To analyze the characteristics and electrogastrogram features of patients with functional dyspepsia (FD) overlapping lower gastrointestinal symptoms (LGS).Methods:The clinical data of 61 patients with FD from January 2018 to December 2020 in the First Affiliated Hospital of Nanjing Medical University were retrospectively analyzed. Among them, FD overlapping LGS was in 33 cases (FD overlapping LGS group), and simple FD in 28 cases (simple FD group). The manifestations of patients with FD overlapping LGS were recorded. The dyspeptic symptom score was assessed using the Rome Ⅳ criteria. Anxiety and depression status were evaluated using the hospital anxiety and depression scale (HADS), and sleep disorder was assessed using the Pittsburgh sleep quality index (PSQI). The electrogastrogram was performed, and the normal slow wave percentage (N%), bradygastria percentage (B%), tachygastria percentage (T%), arrhythmia percentage (A%), dominant frequency, dominant power and postprandial-to-fasting power ratio (PR) were recorded.Results:The most common symptom in FD patients overlapping LGS was lower abdomen distention, the incidence was 84.85% (28/33). The upper abdominal bloating score in FD overlapping LGS group was significantly higher than that in simple FD group: 7.00 (6.50, 7.00) scores vs. 5.00 (0.50, 7.00) scores, and there was statistical difference ( P<0.01); there were no statistical differences in other dyspeptic symptoms scores and total score between the two groups ( P>0.05). The incidences of depression and sleep disorder in FD overlapping LGS group were significantly higher than those in simple FD group: 42.42% (14/33) vs. 14.29% (4/28) and 69.70% (23/33) vs. 39.29% (11/28), and there were statistical differences ( χ2 = 5.77 and 5.68, P<0.05); there was no statistical difference in the incidence of anxiety between the two groups ( P>0.05). In FD overlapping LGS group, the postprandial T% in the gastric fundus and postprandial A% in the gastric body were significantly lower than those before meal: 13.79% (6.79%, 21.46%) vs. 20.69% (12.45%, 27.59%) and 3.45% (0, 6.90%) vs. 6.90% (3.45%, 13.79%), and there were statistical differences ( P<0.01). In simple FD group, the postprandial N% in the gastric fundus was significantly lower than that before meal: 55.92% (43.71%, 70.02%) vs. 69.27% (48.07%, 78.45%), and there was statistical difference ( P<0.05). In the gastric fundus, the preprandial N% in FD overlapping LGS group was significantly lower than that in simple FD group, preprandial B% and T% were significantly higher than those in simple FD group, and there were statistical differences ( P<0.01 or <0.05). In the gastric body, the preprandial N% in FD overlapping LGS group was significantly lower than that in simple FD group, and there was statistical difference ( P<0.05). In the pyloric region, the PR in FD overlapping LGS group was significantly lower than that in simple FD group, and there was statistical difference ( P<0.05). In the overall stomach, the preprandial N% in FD overlapping LGS group was significantly lower than that in simple FD group, the preprandial B% and T% were significantly higher than those in simple FD group, and there were statistical differences ( P<0.01 or <0.05). Spearman correlation analysis result showed that the disease course was not correlated with electrogastrogram parameters in patients with FD overlapping LGS ( P>0.05); the total score of dyspeptic symptoms was positively correlated with postprandial A% in the overall stomach ( r = 0.345, P<0.05), and negatively correlated with postprandial dominant frequency in the overall stomach and pyloric region ( r = -0.357 and -0.473, P<0.05 or <0.01). Conclusions:FD patients can overlap with various LGS. The patients with FD overlapping LGS have more severe dyspepsia symptoms, higher proportions of comorbid depression and sleep disorders, and more severe abnormalities in fasting proximal gastric electrical rhythm and emptying function. The severity of dyspeptic symptoms in patients with FD overlapping LGS is correlated with postprandial gastric electrical rhythm abnormalities.

RÉSUMÉ
Upper gastrointestinal symptoms affect 10% of the population, leading to significant costs and negatively impacting quality of life. Diagnosing disorders such as functional dyspepsia and gastroparesis is challenging due to overlapping symptoms. Gastric emptying scintigraphy (GES) has reproducibility issues. Body Surface Gastric Mapping (BSGM) is an advanced technique for precise and reliable electrophysiological mapping, overcoming the limitations of electrogastrography (EGG). Gastric Alimetry® measures gastric myoelectric potentials, providing valuable diagnostic data. BSGM uses an electrode array to capture gastric activity and requires a standardized protocol for comparable data. The metrics generated help identify specific gastric dysfunction phenotypes, improving diagnostic accuracy. These advancements promise to revolutionize the clinical management of chronic gastric symptoms, making this review essential reading for those interested in gastrointestinal research and treatment.

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.

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.
RÉSUMÉ
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.
RÉSUMÉ
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.
RÉSUMÉ
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.
RÉSUMÉ
Dyspepsia due to pancreatic exocrine insufficiency is a common complication after pancreatectomy； however， due to the lack of simple， efficient， and unified diagnostic methods， standardized treatment standards， and awareness of this disease among surgeons， it is difficult to get adequate diagnosis and treatment. Therefore， this article summarizes the research advances in the definition and pathogenesis of pancreatic exocrine insufficiency， the incidence rate of pancreatic exocrine insufficiency after different surgical procedures， and current diagnostic methods and treatment strategies， in order to provide a reference for further improving the diagnosis and treatment of pancreatic exocrine insufficiency after pancreatectomy.
RÉSUMÉ
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.
RÉSUMÉ
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.
