RESUMEN
OBJECTIVE@#To evaluate the value of capsule endoscopy in children with small intestinal diseases with hematochezia as the chief complaint.@*METHODS@#A retrospective analysis was performed on the clinical data and capsule endoscopy findings of 93 children with hematochezia who were admitted to Children's Hospital of Fudan University from May 2015 to January 2019 and underwent capsule endoscopy. According to the capsule endoscopy findings of the jejunum and the ileum, they were divided into a positive lesion group with 39 patients and a negative lesion group with 54 patients. Related clinical data and the features of lesion on capsule endoscopy were analyzed for the two groups.@*RESULTS@#There were no significant differences in age, sex, duration of capsule endoscopy, gastric transit time, and small intestinal transit time between the positive lesion and negative lesion groups (P>0.05). The positive lesion group had a significantly lower level of hemoglobin than the negative lesion group (P<0.05). Hemoglobin level was negatively correlated with the rate of positive lesions on capsule endoscopy (r=-0.342, P=0.001). Among the 39 patients with positive lesions on capsule endoscopy, the detection of Meckel's diverticulum was the highest (41%), followed by inflammatory bowel disease (21%).@*CONCLUSIONS@#Capsule endoscopy has a certain value in detecting small intestinal diseases, especially diseases in the jejunum and the ileum, in children with lower gastrointestinal hemorrhage.

<p><b>OBJECTIVE</b>To evaluate the efficacy and safety of the parenteral administration of various quantities of amino acid in preterm infants.</p><p><b>METHODS</b>Preterm infants (birth weight 1000-2000 g) recruited into the study were randomized into three groups. High amino acid group (HP): 2.4 g/(kg.d) of amino acid IV within 24 hours after birth increasing by increments of 1.2 g/(kg.d) to a maximum of 3.6 g/(kg. d); medium amino acid group (MP): 1.0 g/(kg.d) of amino acid IV 24 hours after birth, increasing by increments of 0.5 g/(kg.d) until a maximum of 3.0 g/(kg.d); and low amino acid group (LP): 0.5 g/(kg.d) of amino acid on D3, increasing by increments of 0.5 g/(kg.d) until a maximum of 3.0 g/(kg.d) as the final dose.</p><p><b>RESULTS</b>Totally 96 preterm infants were recruited: HP 34, MP 32 and LP 30. There were no significant differences in demographic or clinical characteristics among the 3 groups. HP group showed lower postnatal weight loss (43.4 g, 95% CI 74.3, 12.6) and weight loss% (2.84%, 95% CI 4.79%, 0.71%) than LP group. HP group showed shorter length of stay in NICU (5.25 d), days to reach 2000 g (7.03 d) and days to tolerate 100 kcal/(kg.d) enteral nutrition (4.52 d) than LP group. Cost of hospitalization was significantly lower in HP group than in LP group (-6275 RMB, 1 US$=8 RMB) and MP group (-5715 RMB). Mean serum RBP (D4), threonine and tyrosine levels were significantly higher in HP group than in LP group. Serum insulin levels were similar; mean serum glucose level was lower in HP group than in LP group. HP infants had lower incidence of sepsis than LP infants (21.9% vs 40.0%). There were no significant differences in the levels of blood ammonia, acid-base balance (as determined by pH and NaHCO3-), BUN, Cr, AST, and ALT.</p><p><b>CONCLUSIONS</b>Intensive and early administration of intravenous amino acid [2.4 g/(kg.d)] improves preterm infants' growth and the tolerance of enteral feeding. It also reduces the cost of hospitalization, and the incidence of sepsis.</p>
