[Pancreatitis as the initial manifestation and abdominal lymph node enlargement in a boy].

A boy aged 14 years had abdominal pain as the major manifestation, with elevated serum amylase and lipase. Abdominal ultrasound performed early after onset in another hospital showed enlargement of the pancreas and a reduction in echo. Magnetic resonance cholangiopancreatography (MRCP) showed pancreatic duct dilation and an unclear image of the head of the pancreas.

[Clinical features and prognosis of gastrointestinal injury due to foreign bodies in the upper gastrointestinal tract in children: a retrospective analysis of 217 cases].

Objective: To study the clinical features and prognosis of gastrointestinal injury caused by foreign bodies in the upper gastrointestinal tract in children.

Methods: A retrospective analysis was performed for the clinical data of 217 children who were diagnosed with foreign bodies in the upper gastrointestinal tract complicated by gastrointestinal injury by gastroscopy from January 2011 to December 2016, including clinical features, gastroscopic findings, complications, and prognosis.

Results: Among the 217 children, 114 (52.

[Value of nasojejunal nutrition in the treatment of children with acute pancreatitis].

Objective: To evaluate the feasibility and effectiveness of placement of nasojejunal feeding tube and nasojejunal nutrition feeding in children with acute pancreatitis.

Method: Twenty-two patients (of whom 13 had severe acute pancreatitis and 9 acute mild pancreatitis) who needed nutritional intervention were selected. They were from Department of Gastroenterology and Surgery during the years 2009 - 2012, and they were at high nutritional risk after STONGkid nutrition risk screening.

[Clinical manifestations and endoscopic features of abdominal type Henoch purpura in children].

Objective: To investigate the clinical manifestations and endoscopic features of abdominal type Henoch purpura in children and improve the diagnostic level.

Methods: Retrospective review was made on the clinical, endoscopic and histopathological features of 57 cases of children with Henoch purpura abdominal type who had been hospitalized from Jan. 2002 to May 2007.

[Gastric acid reflux and reflux esophagitis in children].

Objective: To evaluate the significance of gastric acid reflux in children with reflux esophagitis (RE).

Methods: Twenty-four-hour esophageal pH monitoring and gastroscopy were performed in 180 children suffered from vomiting. The relationship between RE, non-esophagitis (NE), non-erosive reflux disease (NERD) and gastroesophageal reflux (GER) was analyzed.

[Prevalence of Helicobacter pylori resistant to clarithromycin, amoxicillin and metronidazole in children].

Objective: To investigate the prevalence of Helicobacter pylori (Hp) resistant to clarithromycin, amoxicillin and metronidazole in children.

Methods: A total of 44 Hp clinical isolates were cultured from children patients with Hp gastritis and peptic ulcer who underwent gastroscopy during the period from October 2002 to November 2003 in Children's Hospital affiliated to Medical College of Zhejiang University. Nineteen of the patients were girls and 25 boys.

[CD4+ and CD8+ T cells in gastric mucosa in children infected with Helicobacter pylori].

Objective: To study the changes of gastric mucosal CD4(+) and CD8(+) T cells in Helicobacter pylori (Hp) infected children.

Methods: Seventy nine patients with digestive tract symptoms were assessed by endoscopy, rapid urease test and histology. Forty four patients had Hp positive chronic superficial gastritis (Hp(+)CSG) and 35 patients had Hp negative chronic superficial gastritis (Hp(-)CSG).

[Prevalence and mechanism of Helicobacter pylori resistance to clarithromycin in children].

Objective: To investigate the prevalence of Helicobacter pylori (H. pylori) resistance to clarithromycin (CLM) in children and to demonstrate the correlation of 23S rRNA gene mutation to clarithromycin resistance of Helicobacter pylori isolates.

Methods: Totally 108 clinical strains of H.

[Evaluation of clinical value of anorectal manometry for diagnosis of Hirschsprung's disease in neonate].

Objective: Hirschsprung's disease (HD), one of the most common causes resulting in lower intestinal obstruction in children, is prone to be misdiagnosed or to be missed from diagnosis because of its atypical clinical symptoms and inconspicuous morphological findings by barium enema X-ray. Recently, this situation has been largely ameliorated by increased comprehension of anorectal kinetics and improvement of instrument for measurement of anorectal pressure. By now, anorectal manometry (ARMM) has been regarded as a routine means for functional assessment and diagnosis for anorectal disease.

[Levels and mRNA expression of interleukin-8 in gastric and duodenal mucosa of children Infected with Helicobacter pylori].

Objective: To determine the changes of IL-8 and IL-8 mRNA in gastric and duodenal mucosa of children with Hp infection, to study the effect of Helicobacter pylori (Hp) infection on the expression of IL-8 and IL-8 mRNA, and to evaluate its possible roles in the pathogenesis of gastric and duodenal mucosal inflammation in Hp related gastroduodenal diseases.

Methods: Biopsy specimens were taken from the antral and duodenal mucosa on endoscopy in patients with or without Hp infection, which was diagnosed by urease test and Warshing-Starry staining. The expression of IL-8 in gastric and duodenal mucosa was determined by ELISA, the expression of IL-8 mRNA was determined by using RT-PCR.
