Effect of somatostatin on postoperative gastrointestinal function and stress level in children with acute abdomen: a prospective randomized controlled study / 中国当代儿科杂志

OBJECTIVES@#To study the effect of somatostatin on postoperative gastrointestinal function and stress level in children with acute abdomen.@*METHODS@#A total of 102 children with acute abdomen who underwent surgery in Xuzhou Children's Hospital from August 2019 to June 2021 were enrolled as subjects and were randomly divided into an observation group and a control group, with 51 children in each group. The children in the control group were given conventional treatment such as hemostasis and anti-infective therapy after surgery, and those in the observation group were given somatostatin in addition to conventional treatment. Peripheral blood samples were collected from both groups before surgery and on days 1 and 5 after surgery. The two groups were compared in terms of the serum levels of endothelin-1 (ET-1), adrenocorticotropic hormone (ACTH), cortisol, gastrin, and motilin, postoperative recovery, and the incidence rate of complications.@*RESULTS@#There was no significant difference in the serum levels of ET-1, ACTH, cortisol, gastrin, and motilin between the two groups before surgery (P>0.05). Compared with the control group, the observation group had significantly lower serum levels of ET-1, ACTH, and cortisol on days 1 and 5 after surgery (P<0.05) and significantly higher levels of motilin and gastrin on day 5 after surgery (P<0.05). Compared with the control group, the observation group had significantly shorter time to first passage of flatus, first bowel sounds, and first defecation after surgery, as well as a significantly shorter length of hospital stay (P<0.05). The incidence rate of complications in the observation group was significantly lower than that in the control group (6% vs 24%, P<0.05).@*CONCLUSIONS@#In children with acute abdomen, somatostatin can significantly reduce postoperative stress response, improve gastrointestinal function, and reduce the incidence rate of complications, thereby helping to achieve a good prognosis.

Effect of herb-partitioned moxibustion at point on plasma motilin and serum gastrin in patients of diabetic gastroparesis / 中国针灸

OBJECTIVE@#To explore the clinical therapeutic effect of herb-partitioned moxibustion at point in patients of diabetic gastroparesis differentiated as spleen and stomach deficiency and retention of turbid dampness as well as its effect mechanism.@*METHODS@#A total of 134 patients with diabetic gastroparesis were randomized into an observation group and a control group, 67 cases in each one. In the observation group, herb-partitioned moxibustion at point was adopted, 40 min each time, once a day for 5 times a week. In the control group, itopride hydrochloride tablets were prescribed for oral administration, 50 mg each time, three times a day. A total of 6 weeks of treatment was required in the two groups. Before and after treatment, the gastroparesis cardinal symptom index (GCSI) scores, 4-hour gastric emptying rate, TCM symptom score, as well as the levels of plasma motilin and serum gastrin were observed in the patients of the two groups. Additionally, the clinical therapeutic effect was evaluated in the two groups.@*RESULTS@#After treatment, the score of every item of GCSI, TCM symptom scores and the levels of plasma motilin and serum gastrin were all reduced as compared with those before treatment in the patients of the two groups (<0.05), and those in the observation group were lower than the control group (<0.05). Regarding 4-hour gastric emptying rates, which were increased as compared with those before treatment in the two group (<0.05), and the rate in the observation group was higher remarkably than that in the control group (<0.05). The total effective rate was 92.5% (62/67) in the observation group, higher than 74.6% (50/67) in the control group (<0.05).@*CONCLUSION@#Herb-partitioned moxibustion at point relieves the clinical symptoms in the patients with diabetic gastroparesis and increases the gastric emptying rate, which is probably related to the regulation of the levels of plasma motilin and serum gastrin.

Regulation of gastrointestinal hormones during laxative activity of gallotannin-enriched extract isolated from Galla Rhois in loperamide-induced constipation of SD rats / 한국실험동물학회지

Regulation of gastrointestinal hormones have been reported in animal models for constipation undergoing laxative therapy when administered herbal products. We undertook to investigate whether the laxative activity of gallotannin-enriched extracts isolated from Galla Rhois (GEGR) affects the regulation of gastrointestinal hormones, by examining the concentration of four hormones and the activation of their receptors in the loperamide (Lop)-induced constipation model. Stool parameters, including number, weight and water content, were significantly recovered in the Lop+GEGR treated group, relative to the Lop+vehicle treated group; however, food intake and water consumption were maintained at a constant level. Also, a similar recovery was detected for thickness of mucosa, muscle and flat luminal surface in the Lop+GEGR treated group. Furthermore, concentration of the four gastrointestinal hormones evaluated, namely, cholecystokinin (CCK), gastrin (GAS), somatostatin (SS) and motilin (MTL), were lower in the Lop+vehicle treated group than the No treated group, but were remarkably enhanced in the Lop+GEGR treated group. Moreover, the downstream signaling pathway of MTL and SS receptors were recovered after GEGR administration. Results of the present study therefore indicate that the laxative effects of GEGR treatment may be tightly related with the regulation of gastrointestinal hormones in the Lop-induced constipation model.

Both groups were fed for 4 consecutive weeks and were compared in terms of incidence rate of feeding intolerance, time to establish full enteral feeding, time to complete meconium excretion, number of spontaneous bowel movements, growth and development, motilin level at 4 and 10 days after feeding, and incidence rate of infection.</p><p><b>RESULTS</b>Compared with the control group, the observation group had a lower rate of feeding intolerance (P<0.05), a shorter duration to full enteral feeding and time to complete meconium excretion (P<0.05), a higher mean number of daily spontaneous bowel movements (P<0.05), higher body weight (1 793±317 g vs 1 621±138 g; P<0.05), head circumference (30.5±1.1 cm vs 30.0±1.6 cm; P<0.05), and body length (43.9±1.2 cm vs 42.1±2.0 cm; P<0.05), a higher motilin level at 4 and 10 days after feeding (P<0.05), and a significantly lower infection rate (P<0.05).</p><p><b>CONCLUSIONS</b>Extensively hydrolyzed formula can increase motilin level, improve gastrointestinal feeding tolerance, promote early growth and development, and reduce the incidence of infection in VLBW and ELBW infants.</p>

Melatonin Attenuates Noise Stress-induced Gastrointestinal Motility Disorder and Gastric Stress Ulcer: Role of Gastrointestinal Hormones and Oxidative Stress in Rats

BACKGROUND/AIMS: There are increasing evidences for gastrointestinal motility disorder (GIMD) and gastric stress ulcer induced by noise stress. The present study was to investigate the reversed effect of melatonin on GIMD and gastric stress ulcer induced by noise stress and potential mechanism. METHODS: Noise stress was induced on rats, and melatonin (15 mg/kg) was administered to rats by intraperitoneal injection. Differences were assessed in gastric residual rate (GRR), small intestine propulsion rate (SPR), Guth injury score, cortisol, gastrointestinal hormones (calcitonin-gene-related peptide and motilin) and oxidative stress markers (superoxide dismutase and malondialde hyde) in blood plasma as well as gastric mucosa homogenate with or without melatonin. The pathological examination of gastric mucosa was also performed. RESULTS: The GRR and SPR were improved by noise stress compared with control (P < 0.05). The pathological examination and Guth injury score revealed gastric stress ulcer. Moreover, the levels of cortisol, motilin and malondialdehyde in blood plasma and malondialdehyde in gastric mucosa homogenate were increased by noise stress (P < 0.05). CGRP and superoxide dismutase activity in both of blood plasma and gastric mucosa homogenate were significantly decreased (P< 0.05). Furthermore, melatonin reversed changes in GRR, SPR, pathological examination, Guth injury score, cortisol, motilin, CGRP, superoxide dismutase activity and malondialdehyde (P < 0.05). CONCLUSIONS: Melatonin is effective in reversing the GIMD and gastric stress ulcer induced by noise stress. The underlying mechanism may be involved in oxidative stress and gastrointestinal hormones.

Effect of Modified Baizhu Powder on Gastrointestinal Functions in Mouse Models with Stomach-cold Functional Dyspepsia / 中国医学科学院学报

<p><b>OBJECTIVE</b>To explore the effect of modified Baizhu (Rhizoma Atractylodis Macrocephalae) powder on the gastrointestinal function in mouse models with stomach-cold functional dyspepsia. Meanwhile,the mouse models were administered with Shihu (dendrobium), a traditional Chinese drug with cold nature and flavour, to explore the way via which it exert its effect on specific symptoms. Methods: Mouse models with stomach-cold functional dyspepsia were established by ice water and ice NaOH. The effects of modified Baizhu powder and dendrobium on mice were observed in terms of water intake, weight change,small intestine propulsion rate, intestinal absorption function, and effects on ghrelin and motilin.</p><p><b>RESULTS</b>The modified Baizhu powder effectively increased food intake, water intake, body weight (P<0.05) and swimming time (P<0.01), increased the small intestine propulsion rate and serum D-xylose content (P<0.05), and up-regulated ghrelin (P<0.05). Also, it showed a trend to down-regulate the motilin, although the change was not statistically significant (P>0.05). In contrast,the use of Shihu aggravated symptoms in the mouse models. Conclusion: The changes in ghrelin and motilin levels may be the neuro-endocrine mechanisms via which the modified Baizhu powder and Shihu exert their effects on mouse models.</p>

After 6 weeks, the gastric emptying rate, small intestinal propulsion ratio and levels of plasma motilin (MTL) and calcitonin gene-related peptide (CGRP), cortisol (CORT) and catecholamines (CA) were observed in all groups.</p><p><b>RESULTS</b>Compared with the control group, the gastric emptying rate, small intestinal propulsion ratio and levels of plasma MTL, CORT and CA were increased significantly (P < 0.01) while the content of CGRP was reduced (P < 0.01) in over-training group. After treated with melatonin, this trend was reversed, that was, the gastric emptying rate, small intestinal propulsion ratio and levels of plasma MTL, CORT and CA were surpressed significantly (P < 0.01) while the content of CGRP was improved obviously (P < 0.01) in over-training group.</p><p><b>CONCLUSION</b>Melatonin plays an important role in protecting gastrointestinal tract from dysfunction, in which MTL, CGRP, CORT and CA are all involved.</p>

Gastric dynamics analysis of TEAS combined SNP induced general anesthesia when controlled hypotension dropped to 60% of the MAP baseline / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To observe the effect of gastric dynamics by transcutaneous electrical acupoint stimulation (TEAS) combined general anesthesia when controlled hypotension dropped to 60% of the mean arterial prenssure (MAP) baseline, and to provide experimental evidence for organ protection in clinical controlled hypotension.</p><p><b>METHODS</b>Eighteen male beagles were randomly divided into three groups, the general anesthesia group (blank), the general anesthesia induced controlled hypotension group (control), and the general anesthesia combined TEAS induced controlled hypotension group (experiment), 6 in each group. Controlled hypotension was performed in the latter two groups with isoflurane inhalation and intravenous injection of sodium nitroprusside (SNP). The mean arterial pressure (MAP) was lowered to 60% of the MAP baseline and kept for 60 min. Controlled hypotension was not performed in Beagles of the control group. For Beagles in the experiment group, TEAS [2/100 Hz, (4 ± 1) mA] was applied to bilateral Hegu (LI4), Quchi (LI11), Zusanli (ST36), and Sanyinjiao (SP6) from stable physiological conditions to the end of maintaining stages. Changes of EGG frequencies and EGG amplitudes were monitored. Serum levels of gastrin (GAS) and motilin (MTL) were also detected at corresponding time points during and after experiment.</p><p><b>RESULTS</b>As for the pressure control effect of TEAS combined general anesthesia in the controlled hypotension, during the process of controlled hypotension (T1-T4), MAP levels of two controlled pressure groups remained relatively stable, and were kept at 60% of the MAP baseline. When the blood pressure dropped to the target low MAP and maintained at 60 min (T1-T4), EGG amplitudes of Beagles in all the three groups showed decreasing tendency. But it was more obviously lower than its basic level in the control group (P <0.05), while it was not obviously decreased in the experiment group (P < 0.05). EGG frequencies of Beagles in all the three groups showed no obvious change during this stage. By the end of the MAP rising stage (T8), the EGG amplitude of the experimental group was significantly higher than that of the control group and the blank group (P < 0.05), while it didn' t show any obvious increase in the control group. During this period, EGG frequencies of the two controlled hypotension groups decreased more than those of the blank group. Two h after rising blood pressure (at T9), EGG amplitudes and frequencies in the two controlled hypotension groups basically restored to their respective baselines and levels of the blank group at T9. At 2 h (T9) after controlled hypotension, serum levels of GAS and MTL were lower than those of basic levels in the two controlled hypotension groups (P <0.05). However, serum levels of GAS and MTL had an increasing trend in the two controlled hypotension groups at 24-72 h (T10-T12). Besides, the increasing speed and amplitude was better in experiment group than in the control group at T10-T12. However, there was no statistical difference between the two groups (P > 0.05). At 72 h (T12) serum levels of GAS and MTL had basically restored to their basic levels in the two controlled hypotension groups and that of the blank control group.</p><p><b>CONCLUSION</b>EGG amplitudes could be effectively improved in TEAS combined general anesthesia for controlled hypotension at 60% of the MAP baseline, the recovery of the serum GAS level accelerated, gastric power improved and stomach protected.</p>

The lower the gestational age, the longer the FI duration. There was a negative correlation between the plasma MOT level on day 1 of life and the FI duration (r=-0.913, P<0.001). Gestational age and prenatal use of glucocorticoid were protective factors for FI, while fetal distress, placental abnormality and perinatal infection were risk factors for FI.</p><p><b>CONCLUSIONS</b>Change in plasma MOT level may be closely related to the development of FI in preterm infants. Early monitoring of plasma MOT level may be useful for predicting the occurrence of FI.</p>

Mechanism of Interdigestive Migrating Motor Complex

Migrating motor complex (MMC) is well characterized by the appearance of gastrointestinal contractions in the interdigestive state. This review article discussed the mechanism of gastrointestinal MMC. Luminal administration of 5-hydroxytryptamine (5-HT) initiates duodenal phase II followed by gastrointestinal phase III with a concomitant increase of plasma motilin release in conscious dogs. Duodenal 5-HT concentration is increased during gastric phase II and phase III. Intravenous infusion of motilin increases luminal 5-HT content and induces gastrointestinal phase III. 5-HT4 antagonists significantly inhibits both of gastric and intestinal phase III, while 5-HT3 antagonists inhibited only gastric phase III. These suggest that gastrointestinal MMC cycle is mediated via the interaction between motilin and 5-HT by the positive feedback mechanism. Gastric MMC is regulated via vagus, 5-HT3/4 receptors and motilin, while intestinal MMC is regulated via intrinsic primary afferent neurons and 5-HT4 receptors. Stress is highly associated with the pathogenesis of functional dyspepsia. Acoustic stress attenuates gastric phase III without affecting intestinal phase III in conscious dogs, via reduced vagal activity and increased sympathetic activity. It has been shown that subset of functional dyspepsia patients show reduced vagal activity and impaired gastric phase III. The physiological importance of gastric MMC is a mechanical and chemical cleansing of the empty stomach in preparation for the next meal. The impaired gastric MMC may aggravate dyspeptic symptoms following a food ingestion. Thus, maintaining gastric MMC in the interdigestive state is an important factor to prevent the postprandial dyspeptic symptoms.

In western medication group, Mosapride 5 mg, three times per day; Omeprazole 20 mg, twice per day and Amitriptyline 25 mg, twice per day were administered for oral application. Six weeks treatment was required in each group. The symptoms score, the Nepean Dyspepsia Symptom Index (NDSI), the Nepean Dyspepsia Life Quality Index (NDLQI), Medical Outcomes Study 36-Item Short Form Health Survey (SF-36), electrogastrography, plasma motilin, gastric emptying by B-sonography and adverse reactions were observed before and after treatment, as well as 4 weeks after treatment separately.</p><p><b>RESULTS</b>Compared with those before treatment, the symptom score and NDSI decreased apparently after treatment (all P < 0.01), NDLQI, SF-36, electrogastrographic frequency, plasma motilin and gastric emptying were up-regulated apparently (all P < 0.01) after treatment in each group. The results of the above-mentioned indices in combined therapy group were superior to the other groups (all P < 0.05). As compared with the condition at the end of treatment, in 4 weeks after treatment, the above indices were not rebound apparently in electroacupuncture group and combined therapy group (all P > 0.05). But they were rebound obviously in Zhizhu Kuanzhong capsule group and western medication group (all P < 0.05). The short-term and long-term efficacies in combined therapy group were significantly higher than the total effective rates in the other groups (P < 0.05, P < 0.01). No serious adverse reaction was reported in each group.</p><p><b>CONCLUSION</b>Electroacupuncture and Zhizhu Kuanzhong capsule all up-regulate plasma motilin and electrogastrographic frequency, promote gastric emptying, alleviate the symptom of functional dyspepsia and improve NDLQI. But the combined medication achieves much better efficacy and presents better safety and long-term therapeutic effect.</p>

Effects and mechanisms of Herba dendrobii on rats with stomach-heat syndrome / 中国中药杂志

<p><b>OBJECTIVE</b>To observe the effects of Herba dendrobii on rats with stomach-heat syndrome and to explore the mechanisms.</p><p><b>METHOD</b>Rats were fed with decoction of Rhizoma Zingiberis for 15 continuous days to induce the model of stomach-heat syndrome. After modeling, Herba Dendrobii (HD) decoction were given (in the doses of 1.5, 0.75 g x kg(-1) respectively) for 10 days. After treatment, amount of the daily diet, volume and absorbance of urine, pellet number and moistness of excrement, color and coating degree of tongue were recorded; the body thermal effects were detected with thermal texture maps (TTM) system; the biochemical indexes of blood reflecting the physiological function of stomach, including thromboxaneB2 (TXB2), 6-keto-prostaglandin F1alpha(6-keto-PGF1alpha), motilin (MTL), gastrin (Gas), somatostation (SS), interleukin-4 (IL-4) and interleukin-8 (IL-8) were measured by radio immunoassay; and the histological changes of gastric mucosa were observed by hematoxylin-eosin (HE) stain.</p><p><b>RESULT</b>The model rat had yellow coating and red tongues (P < 0.05). The amount of daily diet were increased (over 10%), urine volume and excrement pellet number were decreased (over 10%). The their urine color became deep (P < 0.01) and their excrement became dry. The temperatures in head, neck, left fore-armpit, chest, up-abdomen, mid-abdomen of the model rats were raised up (difference > 0.5 degrees C or difference > 1.0 degree C ). The content of 6-keto-PGF1alpha in blood of model rats decreased evidently (P < 0.01), and the contents of MTL, Gas and IL-8 increased conspicuously (P < 0.01). The histological changes of gastric mucosa in the model rats were as follows: diffuse congestion, infiltration of neutrophil, less secretion, decrease of the number of chief and parietal cells, etc (P < 0. 05 or P < 0.01). After treatment with HD, except the daily food weight, the temperatures in head, neck and chest, the content of MTL and the number of chief cells, the other indexes observed above were improved noticeably (difference > 0.5 RC or difference > 1.0 degree C, P < 0.05 or P < 0.01).</p><p><b>CONCLUSION</b>The reason why HD relieves the general symptom and sign the gastric mucosa of rats with stomach-heat syndrome is that HD can increase 6-keto-PGF1alpha and decrease IL-8, Gas, TXB2 in their blood.</p>

Clinical observation on transcutaneous electrical acupoint stimulation for treatment of functional dyspepsia / 中国针灸

<p><b>OBJECTIVE</b>To compare the therapeutic effects of transcutaneous electrical point stimulation and medication on functional dyspepsia.</p><p><b>METHODS</b>Two hundred and fifty cases were randomly divided into an observation group and a control group, 125 cases in each group. The observation group was treated with transcutaneous electrical acupoint stimulation and oral administration of placebo, transcutaneous electrical stimulated at Zusanli (ST 36), Liangmen (ST 21), Taichong (LR 3) etc. The control group was treated with oral administration of Mosapride citrate dispersible tablets, Domperidone and Omeprazole and the placebo treatment of transcutaneous electrical acupoint stimulation, the stimulated position was 3-4 cm to the selected points of the observation group, the amount of the stimulation did not reach the treatment amount. The symptom score, the plasma motilin (MTL) concentration and the somatostatin (SS) concentration were observed before and after treatment of 3 courses.</p><p><b>RESULTS</b>All symptom scores after treatment were lower than that before treatment in the two groups, the scores of the upper abdominal pain, acid regurgitation, belching and abdominal distention in the observation group were significantly lower than that in the control group (P < 0.05, P < 0.01); the treatments of both two groups can increase the plasma MTL concentration and decrease the SS concentration (both P < 0.001), and the plasma MTL concentration in the observation group was significantly higher than that in the control group (P < 0.01), and the SS concentration was significantly lower than that in the control group (P < 0.05).</p><p><b>CONCLUSION</b>Transcutaneous electrical point stimulation can more reduce the symptoms of upper abdominal pain, acid regurgitation, belching and abdominal distention, etc. in the functional dyspepsia patients than medication treatment, and can increase the concentration of the plasma MTL and decrease the SS concentration, thus to improve the gastrointestinal motility.</p>
