Objective To investigate the clinical value of endoscopy for chronic diarrhea in infants and safety of gastroscopy replacing colonoscopy.Methods According to the Nelson chronic diarrhea definition,data of 52 hospitalized infants under 1 year from March 2006 to April 2014,who underwent colonoscopy because of diarrhea lasting for more than 2 weeks and achieving no improvement after series of treatments,or diarrhea suspected with severe milk protein allergy were collected.Endoscopy and mucosal biopsy were performed under intravenous anesthesia.Results A total of 49 cases (94.2%)were found abnormal under endoscopy.Lymphocytes,plasma cells and a little eosinophils were found in lamina propria in 26 cases,20-100 eosinophils/HPF were found in lamina propria in 21 patients,who were diagnosed as eosinophilic colitis.The 21 patients came back for open food challenge test 4 weeks later,16 cases were positive,who were diagnosed as milk protein allergy.Two infants with Crohn disease and ulcerative colitis respectively were treated with mesalazine and prednisone,but symptoms repeated.No complication was observed during endoscopy.Conclusion The etiology of infant chronic diarrhea is complex,except for peptic infections and lactose intolerance ,eosinophilic colitis may be the major cause.Ulcerative colitis and Crohn disease are rare in infants,but cannot be ignored .Endoscopy and mucosal biopsy are important in di-agnosis and treatment.Gastroscopy instead of colonoscopy is safe and effective.

Objective To evaluate the efficacy and safety of composite milk clotting enzyme capsules in children with functional dyspepsia.Methods A multicenter,randomized,open-label clinical trial was carried out in 4Guangzhou hospitals during Feb.2012 to Mar.2013.Children with functional dyspepsia on basis of Rome Ⅲ criteria were enrolled and treated with composite milk clotting enzyme capsules.Total symptom score and drug-related adverse reactions were evaluated after one-week and two-week therapy.The treatment outcome were divided into very effective,fairly effective and ineffective according to the symptom score changes.Superiority test was done for effectiveness of the treatment based on efficacy difference by 10％ regarded as superiority.Results Two hundred and one children were enrolled.One hundred and ninety-six children completed the study as planned.After two-week therapy,better effective rate and total effective rate were 68.88％ and 87.76％,higher than those of one-week therapy (27.04％,76.02％) (U =2.935,P ＜ 0.05).The lower limits of 95 ％ confidence interval of difference in symptoms improve rate,better efficacy rate and symptom score decrease rate between two-week and one-week therapy were more than 10％,and two-week therapy was superior to one-week therapy.No significant drug-related adverse reaction was found during the study.Conclusions Composite milk clotting enzyme capsules can improve functional dyspepsia symptoms significantly.The effectiveness of two-week of treatment is better than that of one-week treatment.No obvious drug-related adverse reaction is observed.

Objective To prepare recombinant human adenovirus type 3 expressing Norovirus cap-sid protein gene(Noro-orf2). Methods The cDNA for Noro-orf2 was amplifed by RT-PCR from stool of in-fantile gastroenteritis and cloned into the adenovirus shuttle vector pBSE3CMV-egfp. The vector pBSE3CMV-Nor was linearized with EeoR Ⅴ and Not Ⅰ, and transformed into E. coil BJ5183 with lined edenovirus ge-nomic DNA pLasmid pBRAdv3 by Rsr Ⅱ. The identification of recombinant adenovirus plasmid pBRAdv3E3dNor was performed by PCR, enzyme digestion and DNA sequencing. Then pBRAdv3E3dNor was digested with AsiS Ⅰ and transfeeted into Hep-2 cells with LipofectAMINETM 2000 to package recombi-nant adenovirus particles. Results Noro-orf2 was successfully inserted into the shuttle vector. The recombi-nant adenoviral plasmid pBRAdv3E3dNor was generated by homologous recombination in E. coil BJ5183 and confirmed by PCR and enzyme digestion. The recombinant adenovirus was successfully packaged and puri-fied. Norovirus eapsid protein gene expression was confirmed in Hep-2 cells by immunecytochemistry assay. Conclusion The recombinant type 3 adenovirus expressing Norovirus eapsid protein gene was successfully constructed. This study laid a foundation for developing vaccine against Norovirus.

Objective To analyze the clinical, endoscopic and histopathological features of eosinophilic gastroenteritis ( EG) in children. Methods A retrospective study of 76 children with EG was performed to analyze clinical symptoms, laboratory and imaging results, endoscopic and pathological features, status of Helicobacter pylori ( H. pylori) infection, treatment and outcomes. Results The main clinical symptoms were abdominal pain in 55. 3%(42/76) cases, vomiting in 39. 5% (30/76) cases and hematochezia in 38. 2% cases( 29/76) . The hemoglobin level decreased significantly in 34 cases ( 44. 7%, 34/76). Peripheral blood eosinophil (EOS) count increased significantly in 9 cases (11. 8%,9/76) and EOS percentage increased significantly in 13 cases(17. 1%,13/76). Total serum IgE elevated in 32 cases ( 54. 2%, 32/59 ) . There were also 18 cases ( 36. 7%, 18/49 ) positive in serum allergen?specific immunoglobulin E ( sIgE) test and 25 cases ( 32. 9%,25/76) positive in fecal occult blood test. Among 51 cases of abdominal ultrasound examination, there were 7 cases of ascites, 4 cases of pelvis fluid and 3 cases of intestinal wall change. Endoscopic examination in 76 cases showed 63 cases ( 82. 9%) of mucosal hyperemia/edema,20 cases ( 26. 3%) of ulceration, 17 cases ( 22. 4%) of erosion, 11 cases ( 14. 5%) of nodularity or hyperplasia and 9 cases ( 11. 8%) of normal mucosa. The pathological examination showed mucosal inflammation with a large number of EOS infiltration(≥20 per HPF).There were 12 cases(15. 8%, 12/76) of H. pylori infection. Among the 76 cases, clinical symptoms improved significantly in 74 patients after treatment with dietary allergen avoidance, anti?allergy medications, antacids, montelukast and corticosteroid, and the total efficacy was 97. 4%. The efficacy of dietary allergen avoidance, anti?allergy medications, antacids and montelukast was 93. 8%( 61/65 ) . The efficacy of corticosteroid was 86. 7%(13/15). Conclusion The clinical manifestations and endoscopic characteristics of EG in children lack specificity. In terms of diagnosis, the elevated total serum IgE and the positive sIgE test may be taken as reference for the diagnosis of EG. The definite diagnosis is based on pathological examination ( EOS infiltration≥20 per HPF).While in terms of treatment, dietary allergen exclusion, anti?allergy medications, antacids and montelukast are highly effective, which can be taken as the first option. There is no need of corticosteroid as routine therapy.

Objective To investigate the infection and epidemiological characteristics of group A rotavirus (RV-A)and adenovirus in children with diarrhea in Guangzhou. Methods The colloidal gold technique was used to detect RV.A and adenovirus antigen in 2,171 stool samples from children with diarrhea in Guangzhou Women and Children′s Medical Center from January to December 2015,and the data were statistically analyzed. Results Among the 2,171 patients,the positive rate of RV-A infection was 17.96%and that of adenovirus infection 8.66%, and the co-infection rate of both virus was 3.45%. The positive rates between different genders were not significantly different(P > 0.05);the infectious time peak of RV-A was January(40.78%),followed by December(39.24%) and February(32.61%)and that of adenovirus infection was July(15.89%)and May(15.79%). The infectious peak of RV-A and adenovirus was December(7.29%),followed by January(7.01%). The peak age of infection ranged from 1y to 3y. Conclusion RV-A and adenovirus are the main pathogens of children diarrhea ,and the onset of virus infection has obvious seasonal change.
