Functional dyspepsia treated with acupuncture of different frequencies: a randomized controlled trial / 中国针灸

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.

Meta-analysis of Simotang Oral Liquid in treatment of functional dyspepsia in adults / 中国中药杂志

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.

Systematic review and Meta-analysis of Biling Weitong Granules in treatment of stomach ache disorder / 中国中药杂志

This study aimed to evaluate the efficacy and safety of Biling Weitong Granules in the treatment of stomach ache disorder. Randomized controlled trial(RCT) of Biling Weitong Granules in the treatment of digestive diseases with stomach ache disorder as the primary symptom was retrieved from Chinese and English electronic databases and trial registration platforms from database inception to June 10, 2022. Two investigators conducted literature screening and data extraction according to the screening criteria. The Cochrane risk-of-bias tool(v 2.0) was used to assess the risk of bias in the included studies. Analyses were performed using RevMan 5.4 and R 4.2.2, with summary estimates measured using fixed or random effects models. The primary outcome indicators were the visual analogue scale(VAS) scores and stomach ache disorder symptom scores. The secondary outcome indicators were clinical recovery rate, Helicobacter pylori(Hp) eradication rate, and adverse reaction/events. Twenty-seven RCTs were included with a sample size of 2 902 cases. Meta-analysis showed that compared with conventional western medicine treatments or placebo, Biling Weitong Granules could improve VAS scores(SMD=-1.90, 95%CI[-2.18,-1.61], P<0.000 01), stomach ache disorder symptom scores(SMD=-1.26, 95%CI[-1.71,-0.82], P<0.000 01), the clinical recovery rate(RR=1.85, 95%CI[1.66, 2.08], P<0.000 01), and Hp eradication rate(RR=1.28, 95%CI[1.20, 1.37], P<0.000 01). Safety evaluation revealed that the main adverse events in the Biling Weitong Granules included nausea and vomiting, rash, diarrhea, loss of appetite, and bitter mouth, and no serious adverse events were reported. Egger's test showed no statistical significance, indicating no publication bias. The results showed that Biling Weitong Granules in the treatment of digestive system diseases with stomach ache disorder as the primary symptom could improve the VAS scores and stomach ache disorder symptom scores of patients, relieve stomach ache disorder, and improve the clinical recovery rate and Hp eradication rate, with good safety and no serious adverse reactions. However, the quality of the original studies was low with certain limitations. Future studies should use unified and standardized detection methods and evaluation criteria of outcome indicators, pay attention to the rigor of study design and implementation, and highlight the clinical safety of the medicine to provide more reliable clinical evidence support for clinical application.

Hemangioma hepático gigante: presentación de caso clínico / Giant hepatic hemangioma: case report

Los hemangiomas hepáticos se consideran las lesiones benignas hepáticas más comunes. Se de-nominan hemangiomas gigantes cuando su diámetro supera los 5 cm. La etiología es poco clara y su mayor prevalencia se ubica en mujeres de mediana edad. A continuación, se presenta el caso de una paciente de 73 años con dispepsia tipo distrés postprandial. La paciente acudió a consulta donde se documentó una masa heterogénea en segmentos hepáticos VI y VII con componente exofítico, realce periférico y llenado centrípeto en fases tardías. Recibió manejo sintomático con buena respuesta clínica y continúa en seguimiento. La presentación de este caso clínico obedece a que el hemangioma hepático es diagnosticado, por lo general, de forma incidental por imágenes abdominales realizadas desde un enfoque distinto en el paciente, y por las numerosas consultas al servicio de salud por síntomas diferentes a los directamente relacionados con el hemangioma hepá-tico. Adicionalmente, puede generar complicaciones asociadas al efecto de masa, y su prevalencia dentro de las lesiones hepáticas benignas es considerable

Hepatic hemangiomas are the most common benign tumors of the liver. They are called giant he-mangiomas when their diameter exceeds 5 cm. The pathophysiology is unclear, and middle-aged women have the highest prevalence. The case of a 73-year-old woman with dyspepsia postprandial distress syndrome is presented. The patient had a heterogeneous mass in the liver segments VI and VII with an exophytic component, peripheral enhancement, and centripetal filling in late phases. The patient received symptomatic treatment with adequate clinical response and continues in observa-tion. The presentation of this clinical report is due to the fact that hepatic hemangioma is generally diagnosed incidentally by abdominal imaging performed from a different approach, and to the numerous visits to the health service due to symptoms other than those directly related to hepatic hemangioma. Additionally, it can involve mass-related complications, and the prevalence within benign liver lesions is substantial.

High prevalence of functional dyspepsia in nonalcoholic fatty liver disease: a cross-sectional study

Abstract BACKGROUND: Gastrointestinal (GI) symptoms are frequent complaints from individuals with nonalcoholic fatty liver disease (NAFLD). Dyspepsia is a universal clinical symptom and is among the most common GI complaints observed in the general population, but its prevalence in the population with NAFLD has not been previously investigated. OBJECTIVE: To compare the prevalence of functional dyspepsia (FD) between patients with NAFLD and controls without liver disease. DESIGN AND SETTING: Cross-sectional study at the Outpatient Liver Clinic, University Hospital, Belo Horizonte, Brazil. METHODS: We included 96 NAFLD patients and 105 controls without liver disease. All participants were assessed for GI symptoms in accordance with the Rome III criteria. Evaluation methods included a questionnaire for FD (validated in Brazil), laboratory tests and upper GI endoscopy. RESULTS: Mean age and sex were similar between the groups. The NAFLD group presented higher frequency of proton-pump inhibitor usage (31.3% vs 4.8%; P < 0.001) and prevalence of FD (25.0% versus 12.4%; P = 0.021). The symptom frequencies were as follows: postprandial distress, 22.9% versus 11.4% (P = 0.030); postprandial fullness, 18.8% versus 10.5% (P = 0.095); early satiation, 8.3% versus 5.7% (P = 0.466); and epigastric pain or burning, 18.8% versus 5.7% (P = 0.004), in NAFLD patients and controls, respectively. Multivariate analysis demonstrated that female sex (odds ratio, OR 6.97; 95% confidence interval, CI: 1.51-32.12; P = 0.013) and NAFLD diagnosis (OR 2.45; 95% CI: 1.14-5.27; P = 0.021) were independently associated with FD occurrence. CONCLUSION: FD occurs more frequently in individuals with NAFLD than in controls without hepatic disease.

Histopathological pattern of endoscopic gastric biopsies in dyspeptic patients in a Nigerian population

Background and Objective: Dyspepsia is one of the most common complaints encountered in the general outpatient and gastroenterology clinics in Nigeria. Histopathological assessment of endoscopic gastric mucosa biopsy is crucial to delineate the exact cause of dyspepsia to guide patients' management. This study aimed to determine and document the histopathological basis of dyspepsia among dyspeptic patients at our facility. Material sand Methods: This was a three year descriptive retrospective study and the materials consisted of all gastric endoscopic biopsies taken from clinically diagnosed dyspeptic patients sent to the Department of Histopathology of the Federal Medical Centre, Owerri, Nigeria. Results: The biopsies were from 64 (53.2%) male patients and 56 (46.8%) female patients, giving a male to female ratio of 1.14:1. The age range of the patients was 28-82 years with a mean of 56 years at presentation. Helicobacter Pylori (H. Pylori) bacilli were identified in the samples of 42 (35%) patients but absent in samples of 78 (65%) patients. The histopathological pattern of the aetiological basis of dyspepsia in this study consisted of gastritis (96, 80%), functional (17, 14.2%), adenocarcinoma (4, 3.3%) and polyps (3, 2.5%). H. Pylori bacilli were seen only in patients with gastritis (42/96, 43.8%), and it affected 19 (45.2%) male patients and 23 (54.8%) female patients. Chronic active H. Pylori associated gastritis (24, 25%) was the most common form of gastritis seen during the study period. Conclusion: The main organic cause of dyspepsia in our setting was chronic gastric followed in the distant by gastric adenocarcinoma and polyp. Dyspepsia and H. Pylori associated gastritis did not show a significant gender predilection

Association between functional dyspepsia and serum levels of brain-gut peptides in children / 中国当代儿科杂志

OBJECTIVES@#To study the association between functional dyspepsia (FD) and serum levels of brain-gut peptides including calcitonin gene-related peptide (CGRP), nesfatin-1, and ghrelin in children.@*METHODS@#A total of 38 children with FD who attended Shengjing Hospital of China Medical University from November 2019 to December 2020 were enrolled as the FD group. Thirty-four healthy children were enrolled as the control group. Serum samples were collected from all of the children. Enzyme-linked immunosorbent assay was used to measure serum levels of CGRP, ghrelin, and nesfatin-1 for comparison between the two groups. The scores of clinical symptoms were determined for the children with FD. Spearman rank correlation analysis was used to investigate the correlation of symptom scores with the serum levels of brain-gut peptides.@*RESULTS@#The FD group had significantly higher serum levels of nesfatin-1 and CGRP than the control group (P<0.05), while there was no significant difference in the serum level of ghrelin between the two groups (P>0.05). The serum level of nesfatin-1 was positively correlated with the symptom score of early satiety (rs=0.553, P<0.001), but was not significantly correlated with the total score of FD (rs=0.191, P=0.250). The serum level of CGRP was positively correlated with the scores of abdominal pain (rs=0.479, P=0.002) and belching (rs=0.619, P<0.001) and the total score of FD (rs=0.541, P<0.001).@*CONCLUSIONS@#CGRP and nesfatin-1 may play an important role in the pathophysiological process of FD.

Effect of electroacupuncture at "Zusanli" (ST 36) on duodenal mast cells, NGF and NTRK1 in rats with functional dyspepsia / 中国针灸

OBJECTIVE@#To observe the effect of electroacupuncture (EA) at "Zusanli" (ST 36) on duodenal mast cells, nerve growth factor (NGF) and neurotrophic tyrosine kinase receptor type 1 (NTRK1), and to explore the mechanism of electroacupuncture at Zusanli (ST 36) on functional dyspepsia (FD).@*METHODS@#Sixty SPF-grade 10-day-old SD rats were randomly divided into a normal group, a model group, a ketotifen group and an EA group, 15 rats in each group. The FD model was prepared by iodoacetamide combined with rat tail clamping method in the model group, the ketotifen group and the EA group. The rats in the ketotifen group were injected intraperitoneally with ketotifen (1 mg•kg-1•d-1) for 7 days; the rats in the EA group were treated with EA at bilateral "Zusanli" (ST 36), with disperse-dense wave, frequency of 2 Hz/50 Hz and intensity of 0.5 mA, 20 min each time, once a day for 14 days. The gastric emptying rate and small intestinal propulsion rate in each group were observed; the morphology of duodenal mucosa was observed by HE staining; the toluidine blue staining was used to observe the number and degranulation of mast cells in duodenal mucosa; the protein and mRNA expressions of NGF, NTRK1 in duodenum were detected by Western blot and real-time PCR; the level of interleukin-1β (IL-1β) in duodenum was measured by ELISA.@*RESULTS@#Compared with the normal group, the gastric emptying rate and small intestinal propulsion rate in the model group were decreased (P<0.01); compared with the model group, the gastric emptying rate and small intestinal propulsion rate in the ketotifen group and the EA group were increased (P<0.01); the small intestinal propulsion rate in the EA group was higher than that in the ketotifen group (P<0.01). In the model group, local defects in duodenal mucosa were observed with a small amount of inflammatory cell infiltration; no obvious abnormality was found in duodenal mucosa of the other groups. Compared with the normal group, the mast cells of duodenal mucosa in the model group were increased significantly with significant degranulation; compared with the model group, the mast cells of duodenal mucosa in the ketotifen group and the EA group were decreased significantly, and the degranulation was not obvious. Compared with the normal group, the protein and mRNA expressions of NGF, NTRK1 as well as the level of IL-1β in duodenum in the model group were increased (P<0.01); compared with the model group, the protein and mRNA expressions of NGF, NTRK1 as well as the levels of IL-1β in duodenum in the ketotifen group and the EA group were decreased (P<0.01, P<0.05); compared with the ketotifen group, the mRNA expression of NGF, as well as the protein and mRNA expressions of NTRK1 in duodenum in the EA group were decreased (P<0.05, P<0.01).@*CONCLUSION@#EA at "Zusanli" (ST 36) could inhibit the activation of duodenal mast cells and regulate the expressions of NGF and its receptor to improve the low-grade inflammatory response of duodenum, resulting in treatment effect on FD.

Tumor infrecuente como causa de dispepsia / Rare tumor as a cause of dyspesia

El pólipo fibroide inflamatorio gástrico es una entidad clínico-patológica rara, la cual representa una incidencia del 0,1 % de todos los pólipos gástricos.Con mayor frecuencia afecta a adultos en un amplio rango de edad, cuyo pico de incidencia es entre la sexta y séptima décadas de la vida. Las lesiones son predominantemente asintomáticas y se detectan incidentalmente en la endoscopia o en las imágenes realizadas por causas no relacionadas. Ocasionalmente, los pólipos fibroides provocan sintomatología, ya sea por su gran tamaño que causa obstrucción de la salida gástrica, o por la erosión de la mucosa que se presenta con sangrado gastrointestinal superior manifiesto u oculto.

The gastric inflammatory fibroid polyp is a rare clinical-pathological entity, representing an incidence of 0.1% of all gastric polyps. It most frequently affects adults in a wide age range, and its incidence peak is between the sixth and seventh decades of life. The lesions remain predominantly asymptomatic and are detected incidentally on endoscopy or imaging for unrelated causes. Occasionally, fibroid polyps cause symptoms due to their large size causing gastric outlet obstruction, or due to mucosal erosion presenting with overt or occult upper gastrointestinal bleeding.

Consumo de alimentos en comederos ambulantes como factor de riesgo para síntomas dispépticos en estudiantes de medicina / Street food consumption as a risk factor for symptoms of dyspepsia in medical students

Resumen Introducción: los estudiantes universitarios muchas veces realizan su alimentación en comederos ambulantes, lo que puede ser causa de sintomatología digestiva, pero esto no se ha evidenciado en estudios en dicha población. Objetivo: determinar si el consumo de alimentos en comederos ambulantes está asociado con síntomas dispépticos en los estudiantes de medicina peruanos. Material y métodos: se realizó un estudio multicéntrico de datos secundarios, del encuestado de 1797 estudiantes de medicina en ocho facultades de medicina, se calculó una potencia estadística del 93 %. El padecimiento de síntomas dispépticos se asoció con el antecedente de consumo de alimentos en comederos ambulantes. Se obtuvo estadísticas de asociación con modelos bivariados y multivariados. Resultados: El rango de dispepsia funcional varió entre el 9 % y el 28 % y el de consumo de alimentos en comederos ambulantes, entre 1 % y 5 %. En el análisis multivariado, consumir alimentos en comederos ambulantes era un factor asociado con la mayor frecuencia de padecer dispepsia funcional (razón de prevalencia ajustada [RPa]: 1,45; intervalo de confianza [IC] 95 %: 1,09-1,94; p = 0,010); además, otras variables que resultaron significativas fueron el sexo femenino (RPa: 1,40; IC 95 %: 1,15-1,71; p = 0,001) y los que comían en horarios similares (RPa: 0,76; IC 95 %: 0,61-0,94; p = 0,012), ajustadas por la edad y el semestre académico que cursaban. Conclusiones: Los estudiantes que consumían sus alimentos en comederos ambulantes tenían mayor frecuencia de padecer síntomas dispépticos, esto debe ser vigilado por las autoridades sanitarias y universitarias, ya que puede generar repercusiones a corto y largo plazo.

Abstract Introduction: University students often eat at street food stalls, which can cause various digestive symptoms, although this has not been evidenced in studies carried out in this population. Objective: To establish whether food consumption in street food stalls is associated with symptoms of dyspepsia in Peruvian medical students. Materials and methods: A secondary data analysis of a multicenter study was conducted. Of 1 797 medical students surveyed in eight medical schools, a statistical power of 93% was calculated. Symptoms of dyspepsia were associated with a history of food consumption in street food stalls. Association statistics were obtained with bivariate and multivariate models. Results: The prevalence of functional dyspepsia varied between 9-28% and food consumption in street stalls between 1-5%. In the multivariate analysis, eating food in the street was a factor associated with a greater frequency of suffering from functional dyspepsia (aPR: 1.45; 95%CI: 1.09-1.94; p=0.010). In addition, other significant variables were the female sex (aPR: 1.40; 95%CI: 1.15-1.71 p=0.001) and people eating at similar times (aPR: 0.76; 95%CI: 0.61-0.94; p=0.012) adjusted for age, and academic term. Conclusions: Dyspepsia symptoms were more common in students who ate their food from street stalls. This should be monitored by health and university authorities, as it can have short- and long-term consequences.

Metástasis de cáncer de mama como colangiocarcinoma perihiliar o lesión tipo Klatskin / Breast cancer metastasis as a cholangiocarcinoma or Klatskin-like lesion

Paciente de sexo femenino de 60 años de edad, con antecedente de carcinoma ductal de mama izquierda, presentó dolor agudo en epigastrio que se acompaña de 6 meses de dispepsia, saciedad precoz y pirosis; con una pérdida de 9 kilogramos en 2 meses. Refirió coluria, negó ictericia y acolia. Las pruebas de función hepática mostraron un patrón de colestasis con elevación de gama glutamiltrasferasa (GGT) y fosfatasa alcalina (FA). Fue diagnosticada con un Colangiocarcinoma perihiliar basado en hallazgos abdominales de tomografía y resonancia, con un nódulo parenquimatoso en el segmento 8 del hígado como un tumor infiltrante periductal. El diagnóstico presuntivo fue el de Tumor de Klatskin, pero la anatomía patológica fue compatible con metástasis de carcinoma ductal de mama (CK7 + / GATA3 +). El informe complementario mostró HER-2 negativo y estrógeno negativo (ER) y progesterona (PR) por lo que el inmunofenotipo final fue ER- / PR-; HER2- con índice de proliferación Ki67 <5%, una metástasis de cáncer de mama triple negativo.

A 60-year-old female, with a medical history of a ductal carcinoma of the left breast, presented with sharp pain in epigastrium with 6 months of dyspepsia, early satiety and pyrosis and with the loss of 9 kilograms in 2 months. She referred choluria and denied jaundice and acholia. Liver function tests showed a cholestasis pattern with only elevated Gama Glutamyl Teransferase and alkaline phosphatase. She was diagnosed with a hilar cholangiocarcinoma based on abdominal CT and MRI findings, with a parenchymal nodule in segment 8 of the liver as a periductal infiltrating tumor. The presumed diagnosis was Klatskin Tumor, but the biopsied site was compatible with breast ductal carcinoma metastasis (CK7 + / GATA3 +). The complementary report showed negative HER-2 and negative estrogen (ER) and progesterone (PR) so the final immunophenotype is ER- / PR-; HER2- with proliferation index Ki67 <5%, a triple-negative breast cancer metastasis.

Epidemiological and clinical features of functional dyspepsia in a region with a high incidence of esophageal cancer in China / 中华医学杂志(英文版)

BACKGROUND@#Functional dyspepsia (FD) has rarely been investigated in areas with a high prevalence of esophageal squamous cell carcinoma (ESCC). This study aims to reveal the epidemiological and clinical features of FD and organic dyspepsia (OD) in such a population.@*METHODS@#A middle-aged and elderly population-based study was conducted in a region with a high incidence of ESCC. All participants completed the Gastroesophageal Reflux Disease Questionnaire and Functional Gastrointestinal Disease Rome III Diagnostic Questionnaire, and they underwent gastroscopy. After exclusion of gastroesophageal reflux disease, uninvestigated dyspepsia (UID) was divided into OD and FD for further analyses.@*RESULTS@#A total of 2916 participants were enrolled from July 2013 to March 2014 in China. We detected 166 UID cases with questionnaires, in which 17 patients with OD and 149 with FD were diagnosed via gastroscopy. OD cases presented as reflux esophagitis (RE), ESCC, and duodenal ulcer. Heartburn (52.94%) and reflux (29.41%) were common in OD, but no symptomatic differences were found between FD and OD. Male sex, low education level, and liquid food were the risk factors for OD, while frequent fresh vegetable consumption was a protective factor. FD included 56 (37.58%) cases of postprandial distress syndrome (PDS), 52 (34.89%) of epigastric pain syndrome (EPS), nine (6.04%) of PDS + EPS, and 32 (21.48%) of FD + functional esophageal disorders. The Helicobacter pylori infection rate in FD patients was not higher than that in the control group (34.23% vs. 42.26%, P = 0.240). Frequent spicy food consumption was associated with PDS (odds ratio [OR]: 2.088, 95% confidence interval [CI]: 1.028-4.243), while consumption of deep well water was protective for PDS (OR: 0.431, 95% CI: 0.251-0.741).@*CONCLUSIONS@#The prevalence of FD was 5.11% in the studied population.

OBJECTIVE@#To evaluate the clinical effect of acupuncture for the improvements in various dyspeptic symptoms of postprandial distress syndrome.@*METHODS@#The secondary analysis on the data of a multi-center randomized controlled trial (RCT) was conducted. 278 patients with postprandial distress syndrome were randomized into an acupuncture group (138 cases) and a sham-acupuncture group (140 cases). In the acupuncture group, acupuncture was applied to Baihui (GV 20), Danzhong (CV 17), Zhongwan (CV 12), Qihai (CV 6), Neiguan (PC 6), Zusanli (ST 36), etc. In the sham-acupuncture group, 6 sites, neither located on meridians nor belonged to meridian acupoints, were selected and punctured shallowly. The duration of treatment was 20 min each time, 3 times a week, for 4 weeks totally in the two groups. The follow-up visit lasted for 12 weeks. The scores of dyspeptic symptoms were compared between the two groups before treatment, during treatment (in week 1, 2, 3 and 4) and during follow-up (in week 8, 12 and 16) separately.@*RESULTS@#Besides the scores of early satiety and vomiting in the sham-acupuncture group in week 1, the scores of the other dyspepsia symptoms during treatment and follow-up were all reduced in the two groups as compared with those before treatment (@*CONCLUSION@#Acupuncture remarkably relieves postprandial fullness, early satiety, upper abdominal bloating and belching in patients with postprandial distress syndrome.

Mechanism of Xiaoyao San in treatment of depression,breast hyperplasia,and functional dyspepsia based on network pharmacology / 中国中药杂志

This study aimed to explore the mechanism of Xiaoyao San(XYS) in the treatment of three diseases of liver depression and spleen deficiency, ie, depression, breast hyperplasia, and functional dyspepsia, and to provide a theoretical basis for the interpretation of the scientific connotation of "treating different diseases with the same method" of traditional Chinese medicines. Traditional Chinese medicine systems pharmacology database and analysis platform(TCMSP) was used to screen the active components of XYS which underwent principal component analysis(PCA) with the available drugs for these three diseases to determine the corresponding biological activities. The targets of XYS on depression, breast hyperplasia, and functional dyspepsia were obtained from GeneCards, TTD, CTD, and DrugBank databases. Cytoscape was used to plot the "individual herbal medicine-active components-potential targets" network. The resulting key targets were subjected to Kyoto encyclopedia of genes and genomes(KEGG) pathway analysis and gene ontology(GO) enrichment analysis. A total of 121 active components of XYS and 38 common targets in the treatment of depression, breast hyperplasia, and functional dyspepsia were collected. The key biological pathways were identified, including advanced glycation and products(AGEs)-receptor for advanced glycation and products(RAGE) signaling pathway in diabetic complications, HIF-1 signaling pathway, and cancer-related pathways. The key targets of XYS in the treatment of depression, breast hyperplasia, and functional dyspepsia included IL6, IL4, and TNF, and the key components were kaempferol, quercetin, aloe-emodin, etc. As revealed by the molecular docking, a strong affinity was observed between the key components and the key targets, which confirmed the results. The therapeutic efficacy of XYS in the treatment of diseases of liver depression and spleen deficiency was presumedly achieved by reducing the inflammatory reactions. The current findings are expected to provide novel research ideas and approaches to classify the scientific connotation of "treating different diseases with the same method" of Chinese medicines, as well as a theoretical basis for understanding the mechanism of XYS and exploring its clinical applications.

Optimization and implementation of clinical trial of acupuncture: reflection on the successful case of acupuncture for postprandial distress syndrome / 中国针灸

Taking the clinical trial of acupuncture in treatment of postprandial distress syndrome as an example, this paper proposes that the acupuncture clinical trial protocol should be optimized in view of acupuncture prescription, acupuncture frequency and outcomes. Besides, the data quality of acupuncture clinical trial should be improved in consideration of data sharing and electronic data capture so as to provide a reference for the majority of researchers to optimize and implement acupuncture clinical trial.

Clinical observation on different needling depth for dyspepsia after ischemic stroke / 中国针灸

OBJECTIVE@#To observe the efficacy difference between conventional needling depth and deep needling for dyspepsia after ischemic stroke.@*METHODS@#A total of 120 patients with dyspepsia after ischemic stroke were randomized into an observation group (60 cases, 4 cases dropped off) and a control group (60 cases, 3 cases dropped off). Basic treatment was given in the both groups. In the observation group, deep needling was applied at Zhongwan (CV 12), Tianshu (ST 25) and Liangmen (ST 21) for 60-70 mm, after even reinforcing-reducing manipulation of lifting-thrusting technique, the needles were withdrew to 35-50 mm. In the control group, the same acupoints as the observation group were selected and punctured for 25 mm. The needles were retained for 30 min, once a day, 6 times a week for 2 weeks in the both groups. The dyspepsia TCM symptom score was observed before treatment, 1 day and 1, 2 weeks into treatment, and the clinical efficacy was evaluated 2 weeks into treatment in the both groups.@*RESULTS@#The effective rate was 92.9% (52/56) in the observation group, which was superior to 78.9% (45/57) in the control group (@*CONCLUSION@#Conventional needling depth and deep needling can both improve the clinical symptoms in patients with dyspepsia after ischemic stroke, and deep needling has faster and better efficacy.

Clinical pathway for the management of uninvestigated Dyspepsia among adults in family and community practice: Updated 2021

Background@#Uninvestigated dyspepsia is a common complaint in family practice in the Philippines. Patients usually seek consult due to severity of symptoms which affect their quality of life. The goals of management are short- and long-term symptom control, with reversal of possible underlying mechanisms, achievable through a combination of pharmacologic and non-pharmacologic interventions.@*Objective@#The main objective of this pathway is to guide family physicians and primary care physicians in the assessment, diagnosis and management of adult patients with uninvestigated dyspepsia through a shared decision-making process.@*Method@#This clinical pathway is an update of the PAFP’s Clinical Pathways for the Management of Dyspepsia in Adults (2016). The current panel utilized the ADAPTE method and prioritized reviewing relevant clinical practice guidelines from 2017 to present. Grading of recommendation was achieved through a mixture of strength of available evidence and a consensus from a panel of experts.@*Summary of Recommendations@#The main changes in the recommendations in this update are as follows: symptom-based classification of dyspepsia, screening for anxiety and depression, family and SCREEM assessment; initiation of therapeutic trial for most patients to whom H. pylori testing is not available; extension of initial PPI treatment to 4-8 weeks, consideration of antacids/alginates for immediate symptom relief, consideration of tricyclic antidepressants for non-responders to initial treatment; symptom-based non-pharmacologic advice, consideration of counseling and other psychosocial interventions; empowerment for self-treatment and as-needed therapy for those who have completed the initial treatment regimen@*Dissemination and Implementation@#This guideline shall be disseminated and implemented at the clinic and organizational level. It will be published in the “The Filipino Family Physician” journal, social media platforms and will be disseminated through PAFP local chapters, training institutions and during the national convention. Non-FCM primary care physicians will also be reached through relevant agencies. It shall be included in the references required during training activities and national exams of accredited training institutions, in coordination with the PAFP committee on Residency Training. It shall be incorporated in checklists for compliance in audits and QA cycles, with support from the PAFP committee on Quality Assurance and that on Standards for Family Practice. Feedback on utility and applicability will be actively sought from the intended users and other stakeholders.

Respuesta inmunológica a varias proteínas del H. pylori en pacientes guatemaltecos / Inmune response to various H. pylori proteins in Guatemalan patients

Se determinó la respuesta inmunológica a proteínas recombinantes de Helicobacter pylori en pacientes dis-pépticos (adultos y niños), pacientes con cáncer gástrico y sus familiares asintomáticos adultos viviendo con ellos. Se utilizó la prueba recomLine® Helicobacter IgG e IgA, y con base en el reconocimiento de los factores de virulencia VacA y CagA se determinó si la cepa de H. pylori era de tipo I o II. El análisis de los datos fue descriptivo y analítico y se estimaron los intervalos de confianza de 95%, con un nivel de error de 0.05 y Odds ratio. El 58.7% (121/206) de los pacientes presentó la bacteria en tinción histológica de biopsia, positividad que disminuyó con la edad y daño histológico. La frecuencia de la respuesta a los anticuerpos IgG fue mayor que IgA, en ambos casos ésta fue menor en los niños. Las proteínas del H. pylori más reconocidas tanto por IgA como IgG fueron VacA y CagA, y la respuesta a las otras proteínas investigadas fue mayor al aumentar el daño histológi-co. La cepa tipo I fue la que predominó en la población en estudio con 66% (136/206). Se deben continuar con los estudios de prevalencia de la cepa tipo I del H. pylori y del reconocimiento de sus antígenos en la población guatemalteca a fin de determinar su utilidad en el diagnóstico y pronóstico de la infección.

The immune response to recombinant Helicobacter pylori proteins was determined in dyspeptic patients (adults and children), patients with gastric cancer and their asymptomatic adults' relatives living with them. The recomLine® Helicobacter IgG and IgA test was used and based on the recognition of the virulence factors VacA and CagA, it was determined whether the H. pylori strain was type I or II. The data analysis was descriptive and analytic, and 95% confidence intervals were estimated, with an error level of 0.05, and Odds ratio. The patients that presented the bacterium in histological biopsy were 58.7% (121/206), positivity that decreased with age and histological damage. The frecuency of response to IgG antibodies was higher than IgA, in both cases it was lower in children. VacA and CagA were the H. pylori proteins most recognized by both IgA and IgG and it was observed that the number of recognized proteins was greater with increasing histological damage. The type I strain was the one that predominated in the study population 66% (136/206). Prevalence studies of the type I strain of H. pylori ant the recognition of its antigens in the Guatemalan population should continue in order to determine its usefulness in the diagnosis and prognosis of infection.
