Objective To compare the clinical symptoms,endoscopic lesions,pathological histological changes,and H.pylori infection between children with bile reflux gastritis (BRG) and non BRG.Methods 287 cases of children with upper gastrointestinal symptoms were diagnosed with gastritis by gastroscopy.They included 58 cases of BRG and 229 cases of non-BRG.The clinical symptoms,endoscopic lesions,pathological histological changes,and H.pylori infection were compared between two groups,respectively.Results Between BRG and non-BRG groups,there werent statistically significant difference in the main clinical symptoms including abdominal pain,anorexia,nausea,and early satiety.Incidence of abdominal distension,vomiting,and hiccups was[84.5％ (49/58) vs 66.8％ (153/229),32.8％ (19/58) vs 17.9％ (41/229),and 29.3％ (17/58) vs 16.6％ (38/229)],respectively,with statistical significance (x2 =6.93,6.18,4.83,P ＜0.05).There weren(t) statistically significant difference in endoscopic lesions congestion,edema,and mucosal plaques between two groups.Incidence of endoscopic gastric erosions and bleeding of two groups was [37.9％ (22/58) vs 22.7％ (52/229),20.7％ (12/58) vs 10.0％ (23/ 229)],respectively; and BRG group was statistically higher than non-BRG group(x2 =5.60,4.90,P ＜ 0.05).For micronodular change,there were 13 cases (22.4％) in BRG group and 86 cases (37.6％) in Non-BRG group,and Non-BRG group was statistically higher than BRG group(x2 =4.69,P ＜ 0.05).For histopathological changes including epithelial cell degeneration,hyperplasia and lamina propria lymphocyte and neutrophil infiltration,there wasnt statistically significant difference between BRG and non-BRG groups.Incidence about pit extension and mucosal vascular expansion of two groups was [10.34％ (6/58) vs 3.1％ (7/229) and 31.0 ％ (18/58) vs 18.3 ％ (42/229)],respectively ; and BRG group was significantly higher than non-BRG group(x2 =5.97,4.51,P ＜ 0.05).There were 7 cases (12.1％) in BRG group and 55 cases (24.0％) about lamina propria lymphoid follicles,and Non-BRG group was significantly higher than BRG group (x2 =3.90,P ＜0.05).H.pylori positive rates were[22.41％ (13/58),and 40.17％ (92/ 229)],respectively.BRG group and non-BRG group were found statistically significant (x2 =6.29,P ＜0.05).Conclusions BRG children with the characteristic symptoms were abdominal distension,vomiting,and hiccup inverse.Endoscopic characteristic performance was gastric erosions,bleeding spots in antral mucosa changes apparently.Mucosal vascular expansion and pit extension may prompt gastric in children with duodenogastric reflux.H.pylori positive rates of those gastric in children with bile reflux were relatively low.The clinical features could help early diagnosis BRG and guide clinical treatment to improve the cure rate.

AIM:To investigate the relevance of the proliferation of megakaryocytic cell line-HEL stimulated by the recombinant human interleukin-13 (IL-13) to the expression of pro-oncogene c-mpl in HEL cells. METHODS: MTT colorimetric assay and reverse transcrition polymerase chain reaction (RT-PCR) are separately used in this study to observe the effect on the proliferation of HEL cells and the expression of c-mpl mRNA in HEL cells by rhIL-13. RESULTS: RhIL-13 stimulated the proliferation of HEL cells and upregulated the expression of c-mpl mRNA in HEL cells. CONCLUSION: Our results suggest that rhIL-13 stimulated the proliferation of HEL cells and provide the evidence that its mechanism is partly because of increasing the pro-oncogene c-mpl expression in HEL cells.

OBJECTIVE:To establish a method for contents determination of rutin,quercetin and total flavonoids in Buck-wheat,and compare the difference of flavone in buckwheat in different varieties and areas. METHODS:HPLC was adopted for content determination of rutin and quercetin:the column was Aglient C18 with mobile phase of methanol-0.4%phosphoric acid(gra-dient elution)at a flow rate of 1 ml/min,detection wavelength was 360 nm,column temperature was 40 ℃,and injection volume was 10 μl;UV spectrophotometry was adopted for content determination of total flavonoids:reference solution was methanol,de-tection wavelength was 360 nm,the standard was rutin. Statistical method was used to analyze the differences among the Fagopy-rum tataricum,F. esculentum and flavonoids of F. tataricum from different areas. RESULTS:The linear range was 0.400 9-16.03 μg for rutin (r=0.999 4) and 0.009 9-0.396 0 μg for quercetin (r=0.999 7),RSDs of precision,stability and reproducibility tests were lower than 2%,recoveries were 99.33%-104.00%(RSD=1.32%,n=9) and 96.92%-101.66%(RSD=1.60%,n=9),re-spectively. The linear range of total flavonoids(recovded by rutin)was 4.14-41.4 mg/L(r=0.999 9),RSDs of precision,stability and reproducibility tests were lower than 2,and recovery was 96.07%-101.96%(RSD=2.63%,n=9). The content of flavonoids on F. esculentum is significantly higher than in F. tataricum from the same area,and F. tataricum in Bijie area is better than other places. CONCLUSIONS:The method is simple,stable,reproducible,and can be used for the contents determination of rutin, quercetin and total flavonoids in F. esculentum. The study can provide theoretical basis for developing and using buckwheat.

Objective To investigate the prevalence of functional dyspepsia (FD) and its relationship with psychological factors in college students of Zhejiang Province. Methods The students of two colleges in Zhejiang Province were selected.The multi-stage stratified random cluster sampling method was conducted.The Rome Ⅲ adult FD diagnosis questionnaire (ROME Ⅲ-DQ) and psychological symptoms self rating scale questionnaire (SCL-90) was applied in the investigation.The data were analyzed by x2 test and t test.Results A total of 1870 college students of Zhejiang Province were surveyed.The prevalence of FD was 5.78％.The prevalence in female was higher than that in male (7.53 ％ vs 4.14 ％,x2 =9.884,P＜0.05).The prevalence in senior students was highest in all grade (x2 =13.83,P＜0.05).In FD subtypes,postprandial distress syndrome was more than epigastric pain syndrome.The functional constipation and functional defecation disorders were most common in the overlap with other functional gastrointestinal disorders. In SCL-90 questionnaire survey,the scores of each factor of FD group were higher than those of the healthy control group.Conclusions The prevalence of FD was high in the college students of Zhejiang Province. The incidence was correlated with psychological factors.

Objective To study the epidemiologic features of functional bowel disorders (FBD)among medical students and science and engineering students in Zhejiang province,China,and to explore the relationship between psychological factors and FBD.Methods This study was a survey of random sampling based on the Rome Ⅲ Diagnostic Questionnaire ( Rome Ⅲ -DQ) conducted from November 2010 to March 2011.The survey was carried out among medical students and science and engineering students respectively in two universities in Zhejiang province.Symptom Check List 90 ( SCL-90 ) was used for psychological analysis.Results Among 1870 participants,1033 were diagnosed as FBD based on Rome Ⅲ criteria,with an overall incidence of 55.24％.The majority cases were unspecified functional bowel disorder,with an incidence of 26.58％ (497/1870),others were functional constipation 16.95％(317/1870),irritable bowel syndrome 6.90％ ( 129/1870),functional bloating 4.12％ (77/1870) and functional diarrhea 0.70％ (13/1870).The prevalence varied in different genders,majors and grades.In the multivariate analysis,women had a higher risk of any FBD than men [ 68.33％ (617/903) vs 43.02％(416/967) ] except for functional diarrhea; and medical students had a higher risk of any FBD than science and engineering students [ 68.53％ ( 734/1071 ) vs 37.42％ ( 299/799 ) ].Generally higher grade undergraduates had relatively higher risks than lower grade students,especially in medical students.Among the participants with FBD,44.05％ (455/1033) had other functional gastrointestinal disorders.In those overlapped parts,9.00％ ( 93/1033 ) had belching disorders,and 8.23％ ( 85/1033 ) had functional dyspepsia.Students with FBD got higher scores in SCL-90 than healthy students.Conclusions This study revealed a high rate of FBD among college students in Zhejiang province.The prevalence varied in different majors,and female higher than male.Psychological factors also had close relationships with FBD.

In this research, Casuarina eguisetifolia Linn was used to verify the broadly suitability of DNA bar-codes in identification of Li-medicine plants and systematic development of species. The genomic DNA of 22 samples collected C. eguisetifolia and its adulterants were amplified by 4 pairs of primers respectively (ITS (inter-nal transcribed spacer), ITS2 (internal transcribed spacer 2), trnH-psbA , rbcL) and sequenced bi-directionally. Obtained sequences were assembled using CodonCode Aligner. The dates were analysised using MEGA5.1 in ac-cordance with the kimura 2-parameter (K2P) model. The neighbor-joining (NJ) phylogenetic trees were construct-ed. Our study demonstrated the efficacy of ITS/ITS2 to distinguish between C. eguisetifolia and other adulterants species at the molecular level. Comparative to the primer of trnH-psbA and rbcL, there was a obviously DNA gap. The NJ trees showed that the several species of Casuarina can be classified to same types to show a obvi-ously monophyly, which the nearest family was Guttiferae. Therefore, ITS/ITS2 regions can accurately distinguish the original plant of Li-medicine. The systematic evolution of Casuarina can be verified in the molecular level.
