OBJECTIVETo study the changes of plasma vasoactive intestinal peptide (VIP) levels and the relationship of plasma VIP levels with feeding intolerance (FI) in preterm infants.

METHODSPlasma VIP concentrations were measured using radioimmunoassay in 53 preterm infants with FI 1, 4, 7 and 14 days after birth. Fifty-nine preterm infants without FI served as the control group.

RESULTSThe fasting plasma concentrations of VIP in the FI group 1, 4 and 7 days after birth (129 ± 46, 144 ± 32 and 166 ± 31 pg/mL respectively) were significantly lower than those in the control group (195 ± 63, 197 ± 31 and 205 ± 34 pg/mL respectively) (P<0.05). The increased plasma VIP concentrations were associated with the increased gestational age, age in days and enteral feeding volume in the FI group. By 14 days, the plasma concentrations of VIP in the FI group (198 ± 41 pg/mL) were similar to those in the control group (202 ± 48 pg/mL) (P>0.05). The younger the infant's gestational age, the more prolonged the FI. Plasma levels of VIP on day 1 of life in the FI group were negatively correlated with the duration of FI (r=-0.799, P<0.05).

CONCLUSIONSPlasma levels of VIP might be related to the development of FI in preterm infants and might serve as a predictor of FI.

OBJECTIVETo determine the therapeutic efficacy and elucidate the probable pharmacological mechanism of Zhizhuwan (ZZ), a known formula for GI/Dysmotility and constipation in Traditional Chinese medicine, in managing constipating diabetes mellitus (DM).

METHODSubjects, composed of both males and females, ranged from 55 to 76 years of age, and had constipating DM. Subjects with severe colon, rectum, heart, renal, or hepatic disease, obesity and those on medications known to alter gastrointestinal motility were excluded. 28 healthy subjects were also recruited. The study group (n = 28) received 90 g per day of ZZ and the control group (n = 28) received 30 mg per day of cisapride for a 1 month period. Conservative therapy was similar in both groups and administered by a person blinded to randomization code. Patients were assessed pre-treatment and post-treatment by a blinded interviewer. A constipation visual analogue scale (CVAS) was constructed to evaluate the patients' constipation status. To analyze neuropeptides motilin (MTL), vasoactive intestinal polypeptide (VIP), substance P (SP) levels in plasma, a radioimmunoassay technique was adopted. Data were analyzed for treatment effects using the "t" test.

RESULTBase line characteristics were similar in both treatment groups. There were significant effects on symptom relief, increases in serum SP level, and decreases in VIP level in both groups (P < 0.05). ZZ was significantly more effective than cisapride in ameliorating patients' subjective symptoms of defecating and stool frequency, and increasing serum SP level (P < 0.05).

CONCLUSIONZZ is beneficial in constipating DM via increasing SP levels and decreasing VIP levels of serum.

OBJECTIVETo study the change in serum intestinal fatty acid binding protein (IFABP) in children with pneumonia and its correlation with gastrointestinal injury.

METHODSA total of 82 children with community-acquired pneumonia who were treated from January to October, 2015 were enrolled, among whom 34 had mild pneumonia and 48 had severe pneumonia. According to pediatric critical illness score (PCIS), the children with severe pneumonia were further divided into non-critical group (25 patients) and critical group (23 patients). Thirty healthy children who underwent physical examination at outpatient service were enrolled as the control group. ELISA was used to measure serum IFABP level, and the acute gastrointestinal injury (AGI) grade was determined for children with severe pneumonia. Serum IFABP level was compared between groups, and the correlations of IFABP with AGI grade and PCIS were analyzed.

RESULTSThe severe pneumonia group showed a significantly higher serum IFABP level than the control group and the mild pneumonia group (P<0.01), and the mild pneumonia group also showed a significantly higher serum IFABP level than the control group (P<0.01). The critical group showed a significantly higher serum IFABP level than the non-critical group (P<0.01). The patients with grade I-IV AGI had significantly higher serum IFABP levels than the control group (P<0.01), and the serum IFABP level increased significantly with the increasing AGI grade (P<0.01). Serum IFABP level was positively correlated with AGI grade (P<0.01) but negatively correlated with PCIS (P<0.01).

CONCLUSIONSChildren with pneumonia experience an increased serum IFABP level which can be used as a sensitive indicator for the early diagnosis of gastrointestinal injury and the evaluation of conditions in children with pneumonia.

OBJECTIVETo analyze the distribution of trimethylamine N-oxide (TMAO) in healthy adults with different risk factors and explore its association with gut microbiota.

METHODSWe collected fasting blood samples and fresh fecal samples from 181 subjects without atherogenesis in the carotid arteries. Plasma TMAO levels of the subjects were determined using stable isotope dilution liquid chromatography-tandem mass spectrometry (LC-MS). The fecal DNA was extracted, and the 16S rRNA V4 tags were amplified and sequenced by Illumina HiSeq 2000. The association between TMAO and classical cardiovascular risk factors were analyzed. Gut microbial community structure was analyzed with QIIME, and LEfSe was used to identify the biomarkers.

RESULTSThe median (IQR) TMAO level was 2.66 (1.96-4.91) µmol/L in the subjects. TMAO level was significantly correlated with body mass index and operational taxonomic units (OTU). Individuals with high TMAO levels were found to have abundant Clostridiales, Phascolarctobacterium, Oscillibacter, and Alistipes but less abundant Anaerosprobacter.

CONCLUSIONChinese subjects have in general low levels of TMAO. TMAO levels are not significantly correlated with the classical cardiovascular risk factors or the gut microbial structures.

PURPOSE: This literature review was performed to assess the effect of raisins on human health. METHODS: A review of Medline was conducted using the keywords: ‘raisins, raisins and health, raisins and cardiovascular disease (CVD), raisins and cancer, raisins and diabetes, raisins and fiber, raisins and colon health, raisins and antioxidants, raisins and inflammation, raisins and dental caries’. The reference lists from previous review articles on raisins and human health and the California Raisin Marketing Board files were reviewed for additional studies. RESULTS: Raisins have one of the highest polyphenolic content and antioxidant ORAC levels compared to other traditional dried fruits. Many of the polyphenols in raisins are well assimilated and bioavailable. Raisin consumption reduces low density lipoprotein (LDL) cholesterol, blood pressure and blood sugar, when compared to equal caloric carbohydrate snacks and is associated with a reduced risk of CVD. The anti-inflammatory and cancer chemopreventive effects of raisins are mixed. Raisin consumption reduces intestinal transit time and positively affects gut microbiota. Raisins produce sustained energy during long term athletic competitions equal to traditional sports energy gels, shots and jelly beans. Raisins produce a non-cariogenic oral environment and do not fit the American Academy of Pediatrics criteria to be considered a choking hazard. CONCLUSIONS: Based on the review of literature, consumption of raisins provide numerous health benefits for promoting general wellness and in the prevention of many chronic diseases including: CVD, type 2 diabetes mellitus (T2DM) gastrointestinal diseases, and dental caries.

BACKGROUND AND AIMS: This research was conducted in order to study the clinical usefulness and stability of the propofol used for sedation during upper gastrointestinal endoscopy. METHODS: The objective of this research was to study one hundred patients, who were chosen based upon their preference to be examined through diagnostic upper gastrointestinal endoscopy accompanied with propofol from July 1998 to August 1998, and who showed normality in the pulmonary function test and ECG. The elements observed were hemodynamic variations, injection dosage, injection time, recovery time and side effects. RESULTS: All patatints had no recollection of the procedure during gastrointestinal endoscopy. It was found that the older the patients were, the less amount of propofol sleep was indued. Systolic blood pressure, diastolic blood pressure and the mean arterial blood pressure were lowered noticeably after sleep, compared with those before the injection of propofol, while the heart rate hardly changed. CONCLUSIONS: Profopol is believed to be a useful sedative for upper gastrointestinal endoscopy. As blood pressre can be lowered however, a cautious attitude should be considered when injecting propofol in the elderly or in patients who have cardiovascular disease.

Dieulafoy's lesion is an uncommon cause of gastrointestinal bleeding. Hemorrhage occurs through mucosal erosion from an abnormally dilated submucosal artery. Although Dieulafoy's lesion is usually located in the stomach, it may occur anywhere in the gastrointestinal tract. We report here on a case of jejunal Dieulafoy's lesion presenting as a mass and short segment stricture on CT and enteroclysis.

Trimethylamine N-oxide (TMAO) is produced when trimethylamine, a waste product of gut microbes, is converted via hepatic flavin monooxygenases. As TMAO is a potential causative factor in various cardiovascular diseases (CVDs) considerable research interest has arisen on its use as a biomarker. Higher TMAO levels are associated with future risk of both incident CVD in the general population and established CVD, including stroke. The addition of TMAO into models with traditional risk factors significantly improved the prediction of future CVD risk. TMAO promotes atherosclerosis and is associated with platelet hyperreactivity and inflammation, which are in turn associated with the development of stroke and its secondary consequences. Additionally, TMAO may play a key mediator role in the relationship between the diet, gut microbiota, and CVD development. Compelling evidence suggesting that TMAO is both a risk factor and prognostic marker of stroke and CVD. Potential therapeutic strategy of diet and drugs in reducing TMAO levels have emerged. Thus, TMAO is a novel biomarker and target in stroke and CVD prevention.
