RESUMEN

Background: The occurrence of gastrointestinal symptoms in cirrhotic patients with gastroesophageal varices (GOV) after endoscopic treatment is obvious, and the role of gastric myoelectrical activity (GMA) and autonomic nerve function imbalance in the development of gastrointestinal symptoms has not been clarified. Aims: To investigate the changes of GMA and autonomic nerve function in cirrhotic patients with GOV after endoscopic treatment. Methods: Twenty-five cirrhotic patients with GOV from May 2019 to October 2019 at the First Affiliated Hospital of Nanjing Medical University were enrolled, and 10 patients with gastric polyp were served as controls. Electrogastrogram (EGG) and heart rate variability (HRV) were detected before the operation, 1 day after the operation and 5 days after the operation in GOV group. For the gastric polyp group, EGG and HRV were detected before the operation and 1 day after the operation. Changes of GMA and autonomic nerve function were compared between the two groups. Results: No significant differences in GMA and autonomic nerve function were found between GOV group and gastric polyp group before and 1 day after the operation (P>0.05). LF, LF/HF were significantly increased 1 day after the operation in GOV group (P0.05). There were no significant differences in GMA and autonomic nerve function 1 day after the operation compared with pre-operation in gastric polyp group (P>0.05). Compared with Child-Pugh A group, Child-Pugh B group had more obvious GMA abnormalities, and the difference was statistically significant (P<0.05). Conclusions: In cirrhotic patients with GOV, the percentage of bradygastria and the sympathetic activity increased, and the vagal activity decreased 1 day after the operation. These results suggest that GMA and autonomic nerve dysfunction may be related to the gastrointestinal symptoms after endoscopic treatment.

RESUMEN

BACKGROUND/AIMS: Postprandial symptoms of fullness and abdominal discomfort are common after fatty meals. Gastric lipases hydrolyze 10% to 20% of dietary triglycerides during the stomach trituration period of digestion. The aim of this study was to evaluate the effects of acid-resistant lipase on upper gastrointestinal symptoms, including fullness and bloating, as well as on gastric myoelectrical activity after healthy subjects ingested a high-fat, liquid meal. METHODS: This study utilized a double-blind, placebo-controlled, crossover design with 16 healthy volunteers who ingested either a capsule containing 280 mg of acid-resistant lipase or a placebo immediately before a fatty meal (355 calories, 55% fat). Participants rated their stomach fullness, bloating, and nausea before and at timed intervals for 60 minutes after the meal. Electrogastrograms were obtained to assess the gastric myoelectrical activity. RESULTS: Stomach fullness, bloating, and nausea increased significantly 10 minutes after ingestion of the fatty meal (p<0.01), whereas normal gastric myoelectrical activity decreased and tachygastria increased (p<0.05). With lipase, reports of stomach fullness were significantly lower compared with placebo (p<0.05), but no effect on gastric myoelectrical activity or other upper gastrointestinal symptoms was observed. CONCLUSIONS: The high-fat meal induced transient fullness, bloating, nausea, and tachygastria in healthy individuals, consistent with post-prandial distress syndrome. Acid-resistant lipase supplementation significantly decreased stomach fullness.

RESUMEN

Objective To investigate the gastrointestinal symptoms in patients with chronic obstructive pulmonary disease (COPD) and explore its possible reasons.Methods Thirty-six patients with stable COPD were divided into mild group [21 cases,forced expiratory volume in first second (FEV1) measured values/predictive values ≥50%] and severe group (15 cases,FEV1 measured values/predictive values < 50%) according to the pulmonary function.Replacement of 19 healthy volunteers as control group.The patients and volunteers completed the Gastrointestinal Symptom Rating Scales (GSRS) scores and received electrogastrography,the plasma vasoactive intestinal peptide (VIP) and intestinal fatty acid binding protein (Ⅰ-FABP) were detected.Results The GSRS scores in severe group and mild group was higher than that in control group[(17.73 ± 4.64),(14.29 ± 5.44) scores vs.(8.00 ± 2.29) scores],and severe group was higher than that in mild group,there was significant difference (P < 0.05).The percentage of normal slow waves of fasting and postprandial,the percentage of bradygastria in severe group and mild group were lower than those in control group,there were significant differences(P < 0.05).The level of VIP in severe group was lower than that in mild group and control group [(36.07 ± 9.22) μ g/L vs.(44.16 ± 7.88),(46.53 ± 4.54) μ g/L],the level of I-FABP was higher than that in mild group and control group [(35.80 ± 11.69) μ g/L vs.(27.40 ±9.53),(23.58 ±8.18) μg/L],there was significant difference (P <0.05),but there was no significant difference between mild group and control group (P > 0.05).Conclusion The patients with COPD are accompanied with serious gastrointestinal symptoms and gastric dysrhythmia,severe COPD can be associated with VIP decrease and Ⅰ-FABP rise in peripheral blood.

RESUMEN

Objective To explore the characteristics of gastric myoelectrical activity induced by meal in obese people.Methods Fourty-one cases of obese subjects were investigated with Digitrapper electrogastrography(EGG) before and after test meal,32 healthy volunteers with normal body mass index were matched as control.Results①Before the meal, the percentage of normal slow waves(N%)in obese group was lower than that in control subjects(55.52?15.7 vs 70.83?14.31,P

RESUMEN

Gastric motility is controlled by gastric myoelectrical activity, which propagates from the proximal body to the distal antrum at a frequency of 3 cycles per minute(cpm). Peritoneal infusion of dialysate may influence on gastric motility in continuous ambulatory peritoneal dialysis(CAPD) patients. To investigate the concentration of dialysate affects the gastric myoelectrical activity in CAPD patients, we performed electrogastrographic studies(EGG) in 13 non-diabetic CAPD patients. EGG was measured noninvasively using abdominal surface electrodes at the fasting state at empty and 2 hours after 1.5% and 4.25% 2,000mL dialysate, respectively. The dominant power (DP) and the percentage of normal slow-wave frequency(NSWF) had significantly decreased after 4.25 % infusion than the baseline. Tachygastria had significantly increased after 4.25% infusion. Changes in the gastric myoelectrical activity after 1.5% was less prominent than that of 4.25%. In conclusion, peritoneal dialysis may influence on gastric myoelectrical activity and higher osmolar solution may more aggrevate gastric myoelectrical activity than lower one.
