RESUMEN

OBJECTIVE: Growth differentiation factor 15 (GDF15), a stress related cytokine, was recently identified as a novel satiety signal acting via the GFRAL receptor located in the hindbrain. Bitter compounds are known to induce satiety via the release of glucagon-like peptide 1 (GLP-1) through activation of bitter taste receptors (TAS2Rs, 25 subtypes) on enteroendocrine cells in the gut. This study aimed to investigate whether and how bitter compounds induce a stress response in intestinal epithelial cells to affect GDF15 expression in patients with obesity, thereby facilitating satiety signaling from the gut. METHODS: The acute effect of oral intake of the bitter-containing medication Plaquenil (hydroxychloroquine sulfate) on plasma GDF15 levels was evaluated in a placebo-controlled, double-blind, randomized, two-visit crossover study in healthy volunteers. Primary crypts isolated from the jejunal mucosa from patients with obesity were stimulated with vehicle or bitter compounds, and the effect on GDF15 expression was evaluated using RT-qPCR or ELISA. Immunofluorescence colocalization studies were performed between GDF15, epithelial cell type markers and TAS2Rs. The role of TAS2Rs was tested by 1) pretreatment with a TAS2R antagonist, GIV3727; 2) determining TAS2R4/43 polymorphisms that affect taste sensitivity to TAS2R4/43 agonists. RESULTS: Acute intake of hydroxychloroquine sulfate increased GDF15 plasma levels, which correlated with reduced hunger scores and plasma ghrelin levels in healthy volunteers. This effect was mimicked in primary jejunal cultures from patients with obesity. GDF15 was expressed in enteroendocrine and goblet cells with higher expression levels in patients with obesity. Various bitter-tasting compounds (medicinal, plant extracts, bacterial) either increased or decreased GDF15 expression, with some also affecting GLP-1. The effect was mediated by specific intestinal TAS2R subtypes and the unfolded protein response pathway. The bitter-induced effect on GDF15/GLP-1 expression was influenced by the existence of TAS2R4 amino acid polymorphisms and TAS2R43 deletion polymorphisms that may predict patient's therapeutic responsiveness. However, the effect of the bitter-tasting antibiotic azithromycin on GDF15 release was mediated via the motilin receptor, possibly explaining some of its aversive side effects. CONCLUSIONS: Bitter chemosensory and pharmacological receptors regulate the release of GDF15 from human gut epithelial cells and represent potential targets for modulating metabolic disorders or cachexia.

RESUMEN

Motilin (MLN) is a peptide hormone originally isolated from the mucosa of the porcine intestine. Its orthologs have been identified in various vertebrates. Although MLN regulates gastrointestinal motility in tetrapods from amphibians to mammals, recent studies indicate that MLN is not involved in the regulation of isolated intestinal motility in zebrafish, at least in vitro. To determine the unknown function of MLN in teleosts, we examined the expression of MLN and the MLN receptor (MLNR) at the cellular level in Japanese medaka (Oryzias latipes). Quantitative PCR revealed that mln mRNA was limitedly expressed in the gut, whereas mlnr mRNA was not detected in the gut but was expressed in the brain and kidney. By in situ hybridization and immunohistochemistry, mlnr mRNA was detected in the dopaminergic neurons of the area postrema in the brain and the noradrenaline-producing cells in the interrenal gland of the kidney. Furthermore, we observed efferent projections of mlnr-expressing dopaminergic neurons in the lobus vagi (XL) and nucleus motorius nervi vagi (NXm) of the medulla oblongata by establishing a transgenic medaka expressing the enhanced green fluorescence protein driven by the mlnr promoter. The expression of dopamine receptor mRNAs in the XL and cholinergic neurons in NXm was confirmed by in situ hybridization. These results indicate novel sites of MLN activity other than the gastrointestinal tract. MLN may exert central and peripheral actions through the regulation of catecholamine release in medaka.

RESUMEN

Motilin is a gastrointestinal hormone that is mainly produced in the duodenum of mammals, and it is responsible for regulating appetite. However, the role and expression of motilin are poorly understood during starvation and the weaning stage, which is of great importance in the seeding cultivation of fish. In this study, the sequences of Yangtze sturgeon (Acipenser dabryanus Motilin (AdMotilin)) motilin receptor (AdMotilinR) were cloned and characterized. The results of tissue expression showed that by contrast with mammals, AdMotilin mRNA was richly expressed in the brain, whereas AdMotilinR was highly expressed in the stomach, duodenum, and brain. Weaning from a natural diet of T. Limnodrilus to commercial feed significantly promoted the expression of AdMotilin in the brain during the period from day 1 to day 10, and after re-feeding with T. Limnodrilus the change in expression of AdMotilin was partially reversed. Similarly, it was revealed that fasting increased the expression of AdMotilin in the brain (3 h, 6 h) and duodenum (3 h), and the expression of AdMotilinR in the brain (1 h) in a time-dependent manner. Furthermore, it was observed that peripheral injection of motilin-NH2 increased food intake and the filling index of the digestive tract in the Yangtze sturgeon, which was accompanied by the changes of AdMotilinR and appetite factors expression in the brain (POMC, CART, AGRP, NPY and CCK) and stomach (CCK). These results indicate that motilin acts as an indicator of nutritional status, and also serves as a novel orexigenic factor that stimulates food intake in Acipenser dabryanus. This study lays a strong foundation for the application of motilin as a biomarker in the estimation of hunger in juvenile Acipenser dabryanu during the weaning phase, and enhances the understanding of the role of motilin as a novel regulator of feeding in fish.

RESUMEN

PURPOSE: To investigate the impacts of remimazolam tosilate on gastrointestinal hormones and motility in patients undergoing gastrointestinal endoscopy with sedation. METHODS: A total of 262 American Society of Anesthesiologists Physical Status I or II patients, aged 18-65 years, scheduled for gastrointestinal endoscopy with sedation, were randomly allocated into two groups (n = 131 each): the remimazolam tosilate group (Group R) and the propofol group (Group P). Patients in Group R received 0.2-0.25 mg/Kg remimazolam tosilate intravenously, while those in Group P received 1.5-2.0 mg/kg propofol intravenously. The gastrointestinal endoscopy was performed when the Modified Observer's Assessment of Alertness/Sedation scores were ≤3. The primary endpoints included the endoscopic intestinal peristalsis rating by the endoscopist; serum motilin and gastrin levels at fasting without gastrointestinal preparation (T0), before gastrointestinal endoscopy (T1), and before leaving the Post Anesthesia Care Unit (T2); and the incidences of abdominal distension during Post Anesthesia Care Unit. RESULTS: Compared with Group P, intestinal peristalsis rating was higher in Group R (P < .001); Group R showed increased motilin and gastrin levels at T2 compared with Group P (P < .01). There was a rise in motilin and gastrin levels at T1 and T2 compared with T0 and at T2 compared with T1 in both groups (P < .01). The incidence of abdominal distension was lower in Group R (P < .05). CONCLUSION: Compared with propofol used during gastrointestinal endoscopy with sedation, remimazolam tosilate mildly inhibits the serum motilin and gastrin levels, potentially facilitating the recovery of gastrointestinal motility.

RESUMEN

Introduction: Motilin is a hormone secreted by specialised enteroendocrine cells in the small intestine, and is known to modulate gastrointestinal motility in humans, regulating the migratory motor complex. It is understudied at least in part due to the lack of commercially available immunoassays. Method: A multiplexed liquid chromatography mass spectrometry (LC-MS/MS) method was optimised to measure motilin, insulin, C-peptide, GIP (1-42) and GIP (3-42). Corresponding active ghrelin concentrations were determined by immunoassay. Ten healthy volunteers with no prior history of gastroenterological or endocrine condition attended after overnight fast and had blood samples taken every 15 minutes for 4 hours whilst continuing to fast, and then further sampling for 2 hours following a liquid mixed meal. Hunger scores were taken at each time point using a visual analogue scale. Normal bowel habit was confirmed by 1 week stool diary. Results: Motilin levels fluctuated in the fasting state with an average period between peaks of 109.5 mins (SD:30.0), but with no evidence of a relationship with either ghrelin levels or hunger scores. The mixed meal interrupted cyclical motilin fluctuations, increased concentrations of motilin, insulin, C-peptide, GIP(1-42) and GIP(3-42), and suppressed ghrelin levels. Discussion: This study highlights the utility of LC-MS/MS for parallel measurement of motilin alongside other peptide hormones, and supports previous reports of the cyclical nature of motilin levels in the fasting state and interruption with feeding. This analytical method has utility for further clinical studies into motilin and gut hormone physiology in human volunteers.

RESUMEN

Objective:To observe the therapeutic effect of vibrating the abdomen on anorexia model rats,as well as its effects on cholecystokinin octapeptide(CCK-8)and motilin(MTL)in the peripheral blood. Methods:Forty young rats were randomly divided into a normal group(n=10)and a modeling group(n=30).Rats in the normal group were fed common feed.The anorexia model was established by the etiological simulation method in the modeling group,and these rats were further randomly divided into a drug group,a vibrating abdomen group,and a model group 3 weeks after the anorexia model was induced,with 10 rats in each group.The drug group was given Jian Wei Xiao Shi Pian by intragastric administration at a dose of 0.72 g/(kg·bw)(0.72 g drug was dissolved in 10 mL purified water).The normal group and the model group were given purified water once a day in the morning.The vibrating abdomen group was treated with vibrating the abdomen once a day for 21 times.The body mass,food intake,serum CCK-8,MTL,gastrin(GAS),neurotensin(NT)levels,and the intestinal propulsion rate of rats in each group were measured. Results:Compared with the model group,the body mass,food intake,serum MTL and GAS levels,and the small intestine propulsion rate increased significantly,and the serum CCK-8 and NT levels,the gastric residual rate decreased significantly in the vibrating abdomen group and the drug group(P<0.05).There were no significant differences between the vibrating abdomen group and the drug group(P>0.05). Conclusion:Vibrating the abdomen increases the food intake and body mass of anorexia model rats,reduces the residue of gastric contents,improves the small intestine propulsion rate,and therefore has a good therapeutic effect on anorexia.The mechanism may be related to inhibiting the secretion of CCK-8 and NT in plasma and promoting the release of MTL and GAS in serum.

RESUMEN

The direct infusion of bitter solutions in the gastrointestinal tract can reduce the secretion of orexigenic hormones and influence appetite and food intake. We aimed to explore whether oral ingestion of the bitter tastant hydroxychloroquine sulfate can exert similar effects. Ten lean adult women were included in this double-blind, randomized, two-visit, crossover study. After an overnight fast, each volunteer received film-coated tablets containing 400 mg of hydroxychloroquine sulfate (Plaquenil®) or placebo. Plasma-ghrelin, -motilin, -insulin and blood-glucose concentrations were determined every 10 min before and 30 min after feeding; appetite was scored every 10 min. Hunger scores were investigated with a special interest 50-60 min after the ingestion of hydroxychloroquine sulfate, right before a rewarding chocolate milkshake was offered to drink ad libitum. Compared with the placebo, hydroxychloroquine sulfate tended to reduce hunger at the time of interest (p = 0.10). No effect was found upon subsequent milkshake intake. Motilin plasma concentrations were unaltered, but acyl-ghrelin plasma concentrations decreased after the ingestion of hydroxychloroquine sulfate (t = 40-50; p < 0.05). These data suggest that the oral intake of hydroxychloroquine sulfate tablets reduces subjective hunger via a ghrelin-dependent mechanism but does not affect motilin release, hedonic food intake or insulin levels in healthy women.

RESUMEN

The peptide hormone ghrelin (an agonist) and LEAP2 (an antagonist) play important functions in energy metabolism via their receptor GHSR, an A-class G protein-coupled receptor. Ghrelin, LEAP2, and GHSR are widely present from fishes to mammals. However, our recent study suggested that fish GHSRs have different binding properties to ghrelin: a GHSR from the lobe-finned fish Latimeria chalumnae (coelacanth) is efficiently activated by ghrelin, but GHSRs from the ray-finned fish Danio rerio (zebrafish) and Larimichthys crocea (large yellow croaker) have lost binding to ghrelin. Do fish GHSRs use another peptide as their agonist? In the present study we tested to two fish motilins from D. rerio and L. chalumnae because motilin is distantly related to ghrelin. In ligand binding and activation assays, the fish GHSRs from D. rerio and L. crocea displayed no detectable or very low binding to all tested motilins; however, the fish GHSR from L. chalumnae bound to its motilin with high affinity and was efficiently activated by it. Therefore, it seemed that motilin is not a ligand for GHSR in the ray-finned fish D. rerio and L. crocea, but is an efficient agonist for GHSR in the lobe-finned fish L. chalumnae, one of the closest fish relatives of tetrapods. The results of present study suggested that GHSR might have two efficient agonists, ghrelin and motilin, in ancient fishes; however, this feature might be only preserved in some extant fishes with ancient evolutionary origins.

RESUMEN

Rabbit duodenum has been used for examining the ability of motilin to cause muscle contraction in vitro. A motilin-related peptide, ghrelin, is known to be involved in the regulation of gastrointestinal (GI) motility in various animals, but its ability to cause rabbit GI contraction have not been well examined. The aim of this study is to clarify the action of rat ghrelin and its interaction with motilin in the rabbit duodenum. The mRNA expression of ghrelin and motilin receptors was also examined using RT-PCR. Rat ghrelin (10-9-10-6 M) did not change the contractile activity of the duodenum measured by the mean muscle tonus and area under the curve of contraction waves. In agreement with this result, the distribution of ghrelin receptor mRNA in the rabbit GI tract varied depending on the GI region from which the samples were taken; the expression level in the duodenum was negligible, but that in the esophagus or stomach was significant. On the other hand, motilin (10-10-10-6 M) caused a concentration-dependent contraction by means of increased mean muscle tonus, and consistently, motilin receptor mRNA was expressed heterogeneously depending on the GI region (esophagus = stomach = colon = rectum < duodenum = jejunum = ileum < cecum). Expression level of motilin receptor was comparable to that of ghrelin receptor in the esophagus and stomach. Pretreatment with ghrelin (10-6 M) prior to motilin did not affect the contractile activity of motilin in the duodenum. In conclusion, ghrelin does not affect muscle contractility or motilin-induced contraction in the rabbit duodenum, which is due to the lack of ghrelin receptors. The present in vitro results suggest that ghrelin might not be a regulator of intestinal motility in rabbits.

RESUMEN

OBJECTIVE: To observe and explore the effect of Fuling () in alleviating the spleen deficiency symptom pattern (SDSP). METHODS: We established an animal model of SDS in Sprague-Dawley () rats by treating them with deficiency-inducing factors, including irregular feeding and tail clamping. Mice were administered Fuling () and its extracts (raw/cooked powder, aqueous/alcohol extract) by gavage once a day for 21 d. The body weight, rectal temperature, and spleen and thymus organ coefficients were calculated. The levels of motilin (MTL), gastrin (GAS), aquaporin 2 (AQP2), interleukin 2 (IL-2), IL-4, and 5-hydroxytryptamine (5-HT) in the serum and the level of AQP2 in the kidneys were evaluated by enzyme-linked immunosorbent assay. RESULTS: Fuling () and its extracts did not change the body weight, rectal temperature, and organ coefficients of the spleen and thymus. However, it reduced the levels of MTL and GAS and increased the levels of IL-2 and AQP2. In addition, the levels of IL-4 and 5-HT showed no significant alteration. CONCLUSIONS: These results suggested the crucial function of () in SDSP, especially promoting digestive function and water metabolism.

RESUMEN

Aims: To observe the effects of intrathecal administration of motilin on pain behavior and expression of motilin (MTL)/motilin receptor (MTLR) in the spinal cord of a rat model of acute incisional pain. Methods: An incisional pain model was established in rats using a unilateral plantar incision. The rats were also injected intrathecally with 1, 5, or 25 µg of motilin. The mechanical withdrawal threshold (MWT) and thermal withdrawal latency (TWL) were determined. MTL/MTLR expression in the spinal cord was detected by western blotting and immunofluorescence. The expression of MTL in the spinal cord, stomach, duodenum, and plasma was determined by enzyme-linked immunosorbent assay (ELISA). Results: Motilin/motilin receptor were detected in the spinal cord. Spinal cord MTL/MTLR expression peaks at 2 h after modeling (P < 0.05) and start to decrease at 24 h (P < 0.05) to almost reach baseline levels at 72 h. The changes in gastric, duodenal, plasma, and spinal cord motilin levels correlated with MWT and TWL (all R 2 > 0.82). The intrathecal injection of 1, 5, or 25 µg of motilin could increase the pain threshold of rats with incisional pain within 72 h in a dose-dependent manner. Conclusion: This study showed for the first time that MTL/MTLR are expressed in rats' spinal dorsal horn. Acute pain increased MTL/MTLR expression in the spinal dorsal horn. Also, for the first time, this study showed that motilin intrathecal injection alleviates pain in rat models of acute incisional pain. These results suggest that MTL/MTLR could be a novel target for the management of acute pain.

RESUMEN

SUMMARY OBJECTIVE: Functional constipation is the most common form of constipation, and its exact aetiology is still unclear. However, it is known that deficiencies in hormonal factors cause constipation by changing physiological mechanisms. Motilin, ghrelin, serotonin acetylcholine, nitric oxide, and vasoactive intestinal polypeptide are factors that play a role in colon motility. There are a limited number of studies in the literature where hormone levels and gene polymorphisms of serotonin and motilin are examined. Our study aimed to investigate the role of motilin, ghrelin, and serotonin gene/receptor/transporter polymorphisms in constipation pathogenesis in patients diagnosed with functional constipation according to the Rome 4 criteria. METHODS: Sociodemographic data, symptom duration, accompanying findings, the presence of constipation in the family, Rome 4 criteria, and clinical findings according to Bristol scale of 200 cases (100 constipated patients and 100 healthy control) who applied to Istanbul Haseki Training and Research Hospital, Pediatric Gastroenterology Outpatient Clinic, between March and September 2019 (6-month period) were recorded. Polymorphisms of motilin-MLN (rs2281820), serotonin receptor-HTR3A (rs1062613), serotonin transporter-5-HTT (rs1042173), ghrelin-GHRL (rs27647), and ghrelin receptor-GHSR (rs572169) were detected by real-time PCR. RESULTS: There was no difference between the two groups in terms of sociodemographic characteristics. Notably, 40% of the constipated group had a family history of constipation. The number of patients who started to have constipation under 24 months was 78, and the number of patients who started to have constipation after 24 months was 22. There was no significant difference between constipation and control groups in terms of genotype and allele frequencies in MLN, HTR3A, 5-HTT, GHRL, and GHSR polymorphisms (p<0.05). Considering only the constipated group, the rates of gene polymorphism were similar among those with/without a positive family history of constipation, constipation onset age, those with/without fissures, those with/without skin tag, and those with type 1/type 2 stool types according to the Bristol stool scale. CONCLUSION: Our study results showed that gene polymorphisms of these three hormones may not be related to constipation in children.

RESUMEN

The effects of newt motilin on the contractility of the isolated gastrointestinal (GI) tract from Japanese fire belly newts (newt) were examined to clarify whether motilin regulates GI motility in urodele amphibians. In addition, contractile responsiveness to motilins from seven species of vertebrates (human, chicken, turtle, alligator, axolotol, newt and zebrafish) were compared in GI preparations from three different animals (rabbit duodenum, chicken ileum and newt stomach) to determine the species-specific action of motilin. Newt motilin (10-10 M - 10-6 M) caused a contraction of cognate gastric strips, while the upper, middle, and lower intestinal strips were insensitive. The rank order of motilins for contractile activity in newt gastric strips was newt > alligator > axolotol > chicken > turtle > human ≫ zebrafish. On the other hand, newt motilin caused a weak contraction in the rabbit duodenum (human > alligator = chicken > turtle > newt ≧ axolotol > zebrafish), and it was ineffective in the chicken ileum (chicken > turtle > alligator > human ≫ newt, axolotol and zebrafish). This study demonstrates that motilin induces contraction in the GI tract of a urodele amphibian, the newt, in a region (stomach)-specific manner and further indicates that a ligand-receptor interaction of the motilin system is a species-specific manner probably due to differences in the amino acid sequence of motilin.

RESUMEN

Motilin is a gastrointestinal hormone secreted by the duodenum. This peptide regulates a characteristic gastrointestinal contraction pattern, called the migrating motor complex, during the fasting state. Motilin also affects the pressure of the lower esophageal sphincter, gastric motility and gastric accommodation in the gastrointestinal tract. Furthermore, motilin induces bile discharge into the duodenum by promoting gallbladder contraction, pepsin secretion in the stomach, pancreatic juice and insulin secretion from the pancreas. In recent years, it has been shown that motilin is associated with appetite, and clinical applications are expected for diseases affected by food intake, e.g. obesity, by regulating motilin levels. Gastric acid and bile are the two major physiological regulators for motilin release. Caloric foods have varying effects on motilin levels, depending on their composition. Among non-caloric foods, bitter substances reduce motilin levels and are therefore expected to have an appetite-suppressing effect. Various motilin receptor agonists and antagonists have been developed but have yet to reach clinical use.

RESUMEN

ObjectiveTo explore the clinical efficacy of Huanglian Jiedutang as an adjunctive treatment for acute cerebral infarction complicated with gastric motility disorder. MethodSixty patients with acute cerebral infarction complicated with gastric motility disorder with fire toxin syndrome were randomly divided into a western medicine control group （control group） and a traditional Chinese medicine （TCM） combined treatment group （observation group）， with 30 cases in each group. The control group received basic treatment for cerebral infarction and relevant western medical symptomatic treatment based on the patients' gastrointestinal symptoms. The observation group received Huanglian Jiedutang in addition to the treatment provided to the control group. The treatment course was 7 days. Neurological deficit scores and gastrointestinal dysfunction scores were assessed in both groups before treatment and on the 4th and 7th days of treatment. Gastrointestinal electrographic parameters， serum citrulline （CIT）， and motilin （MTL） levels were measured in both groups before treatment and on the 7th day of treatment. Clinical efficacy was compared between the two groups. ResultCompared with the baseline in both groups， the neurological deficit scores and gastrointestinal dysfunction scores were significantly reduced on the 4th and 7th days of treatment （P<0.05）. The reductions in these scores were more significant on the 7th day compared with those on the 4th day of treatment （P<0.05）. On the 4th and 7th days of treatment， the observation group showed a significantly greater reduction in neurological deficit scores and gastrointestinal dysfunction scores compared with the control group （P<0.05）. On the 7th day of treatment， compared with the baseline， both groups showed a significant increase in gastric antral and gastric body electric wave amplitudes as well as serum CIT and MTL levels （P<0.05）， and there were no statistically significant differences in the frequency of gastric antral and gastric body electric waves. On the 7th day of treatment， compared with the control group， the observation group had a significant increase in gastric antral and gastric body electric wave amplitudes as well as serum CIT and MTL levels （P<0.05）， and there were no statistically significant differences in the frequency of gastric antral and gastric body electric waves. After 7 days of treatment， the total effective rate in the observation group was 90.00% （27/30）， higher than 76.67% （23/30） in the control group， but the difference was not statistically significant. ConclusionAdjunctive treatment with Huanglian Jiedutang can effectively improve the symptoms of neurological function impairment and gastrointestinal dysfunction in patients with acute cerebral infarction complicated with gastric motility disorder， increase gastric antral and gastric body electric wave amplitudes， improve gastric motility disorder， and increase serum CIT and MTL levels， thereby improving the imbalanced secretion function of the gastrointestinal tract.

RESUMEN

Objective:To investigate the curative effects of omeprazole combined with amoxicillin on chronic gastritis and patients' quality of life.Methods:A total of 350 patients with chronic gastritis who received treatment in Jinan Seventh People's Hospital from May 2018 to August 2020 were included in this study. They were randomly divided into control and observation groups ( n = 175/group). The control group was treated with omeprazole, and the observation group was treated with omeprazole combined with amoxicillin. Curative effects, inflammatory factor levels, gastric motility, quality of life score, and the incidence of adverse reactions were compared between the two groups. Results:The response rate in the observation group was significantly higher than that in the control group [95.43% (167/175) vs. 86.86% (155/175), χ2 = 5.59, P = 0.018). Before treatment, there were no significant differences in C-reactive protein, interleukin-6, and tumor necrosis factor-α levels between the two groups (all P > 0.05). After treatment, C-reactive protein, interleukin-6, and tumor necrosis factor-α levels in the observation group were (47.97 ± 8.59) mg/L, (38.82 ± 6.29) μg/L, and (38.77 ± 5.92) μg/L, respectively, which were significantly lower than (51.34 ± 9.77) mg/L, (41.20 ± 7.53) μg/L, (41.09 ± 6.85) μg/L in the control group ( t = 3.42, 3.20, 3.39, all P < 0.05). Before treatment, there were no significant differences in serum gastrin-17 and motilin levels between the two groups (both P > 0.05). After treatment, serum gastrin-17 and motilin levels in the observation group were (380.49 ± 61.27) ng/L and (514.42 ± 68.73) ng/L, respectively, which were significantly higher than (362.25 ± 50.16) ng/L and (495.43 ± 61.36) ng/L in the control group ( t = 3.04, 2.72, both P < 0.05). After treatment, the quality of life score in the observation group was significantly higher than that in the control group ( P < 0.05). There was no significant difference in the incidence of adverse reactions between the two groups ( P > 0.05). Conclusion:Omeprazole combined with amoxicillin is highly effective on chronic gastritis. The combined therapy can reduce inflammatory responses, improve gastric motility, improve patients' quality of life, and is highly safe.

Objective:To investigate the effects of laparoscopic total extraperitoneal hernia repair (TEP) on respiratory function and motilin (MOL) in elderly patients with inguinal hernia.Methods:One hundred and twenty elderly patients with inguinal hernia admitted in Chongqing Fengdu People′s Hospital from January 2020 to December 2021 were divided into two groups according to the method of operation, 60 patients who performed laparoscopic preperitoneal hernia repair (TAPP) was enrolled in control group, and 60 patients who performed TEP was enrolled in the study group. The operation index, visual analogue scale (VAS) scores at different time, respiratory function index and gastrin (GAS), MOL levels and postoperative complications were compared between the two groups.Results:Compared with the control group, the operation time in the study group was longer, the recovery time was shorter and the VAS scores were lower on the 1st, 3rd and 7th day after operation: (66.36 ± 10.05) min vs. (53.69 ± 8.59) min, (4.09 ± 0.59) d vs. (5.15 ± 1.06) d, (4.49 ± 1.26) scores vs. (5.46 ± 1.48) scores, (3.65 ± 0.58) scores vs. (4.52 ± 0.95) scores, (2.42 ± 0.41) scores vs. (3.54 ± 0.48) scores, there were statistical differences ( P<0.05). The levels of end-expiratory carbon dioxide pressure (P ETCO 2) and airway pressure (Paw) in the study group at 10, 30 and 90 min postoperatively were higher than those in the control group: (40.66 ± 4.52)mmHg(1 mmHg = 0.133 kPa) vs. (37.48 ± 5.26) mmHg, (19.88 ± 1.63) cmH 2O (1 cmH 2O = 0.098 kPa) vs. (16.59 ± 2.15) cmH 2O; (44.65 ± 4.18) mmHg vs. (41.58 ± 4.58) mmHg, (20.49 ± 1.65) cmH 2O vs. (16.95 ± 2.84) cmH 2O; (50.16 ± 3.54) mmHg vs. (45.59 ± 4.65)mmHg, (21.69 ± 1.78) cmH 2O vs. (17.49 ± 2.15) cmH 2O, there were statistical differences ( P<0.05). The levels of MOL and GAS in the study group at 3 d postoperatively were higher than those in the control group: (396.54 ± 13.58) ng/L vs. (332.52 ± 16.95) ng/L, (118.95 ± 8.95) ng/L vs. (102.58 ± 10.65) ng/L, there were statistical differences ( P<0.05). There was no significant difference in the incidence of complications between the two groups ( P>0.05). Conclusions:Both TEP and TAPP have certain therapeutic effects on the inguinal hernia, but TEP has shorter postoperative recovery time, less pain, less impact on gastrointestinal function, but it will have a certain impact on respiratory function.
