The clinical symptoms were improved after hypoaller-genic diet, amino acid formula and anti-allergy treatment. Conclusions Eosinophilic gastroenteritis is characterized by eosino-phil infiltration with unknown pathogenic factor leading the treatment of eosinophilic gastroenteritis lacking of sound evidence.

Objective: To investigate the mechanism of Glytan lowering portal pressure induced by biliary liver fibrosis. Methods: SD male rats, 240-260g weight around, were randomly divided into sham-operation group, model group, propranolol group, Glytan high-dose, middle-dose and low-dose group according to the weight. Portal hypertension was induced by common bile duct ligation in rats. After two and four weeks, measured the portal pressure(PP) of each group, observed the histological changes of liver by HE staining, tested liver function and the concentration of endothelin-1 in systemic circulation and mesenteric circulation radioimmnuoassay. Results: After two and four weeks, portal pressure of model group rats increased significantly. Both Glytan and propranolol can decrease PP after two and four weeks, and the pressure-relief effect was similar between the two drugs. HE staining showed that Glytan can significantly inhibit the formation of collagen, promote the recovery of liver tissue structure; liver function indicated a significant decrease in serum AST, ALT, TBIL and Na+ concentration. In addition, Glytan decreased the concentration of endothelin -1 in systemic circulation, increased it in mesenteric circulation after two weeks. Conclusion: Glytan decrease PP by improving liver function and microcirculation, inhibiting collagen formation and water-sodium retention after long-term therapy, ameliorating hyperdynamic circulation at the early stage.

Objective To explore the clinical effect and lung CT change of long-term used of low-dose roxithromycin in treatment for bronchial expansion patients in stable phase. Methods 94 cases collected in the Department of Respiration, The Second Hospital Affiliated to Suzhou University from February 2011 to December 2012 were diagnosed as bronchiectasis, 34 cases in control group were given oral treatment for ambroxol 30 mg, three times one day, 60 cases in treatment group were added roxithromycin 75 mg on basis of control group, two times one day. Patients in two groups were both treated for 6 months. The therapeutic effect and the score of life quality and dyspnea scores in two groups were observed, and the changes of CT data were compared before and after treatment. Results After treatment, the life quality score and dyspnea score of two groups were all improved, but the treatment group was signiifcantly higher than the control group (P<0.05). The effective rate in treatment group was 86.67%, which was signiifcantly higher than 70.59%in the control group (P<0.05). After treatment, chest CT imaging score of patients in treatment group were improved, signiifcantly better than that in the control group (P<0.05). Conclusion Long-term low dose administration of roxithromycin can control and stable bronchiectasis symptoms, and improve signs and symptoms .

BACKGROUND:Human bone marrow cells-derived extracellular matrix can promote proliferation of human periodontal ligament stem cells and maintain stem cellproperties.
OBJECTIVE:To preliminarily investigate the effect of human bone marrow cells-derived extracellular matrix on the proliferation of human periodontal ligament stem cells.
METHODS:Human periodontal ligament stem cells and bone marrow cells were separately derived from human periodontal tissue and jaw bone marrow, and human bone marrow cells-derived extracellular matrix was prepared. Human periodontal ligament stem cells were cultured and purified using limited dilution cloning method, and transmission electron microscope was used for ultrastructure observation. Human periodontal ligament stem cells at passage 2 were cultured with human bone marrow cells-derived extracellular matrix and normal culture medium (control group). The cellcounting kit-8 and flow cytometry were used to determine the proliferation potential of human periodontal ligament stem cells cultured on human bone marrow cells-derived extracellular matrix.
RESULTS AND CONCLUSION:Compared with the control group, human periodontal ligament stem cells cultured on human bone marrow cells-derived extracellular matrix had a superior capacity of proliferation (P<0.05), and the cells met their morphological and biological characteristics, and grew in good conditions. Human bone marrow cells-derived extracellular matrix is a promising matrix for large-scale expanding human periodontal ligament stem cells for future use in stem cel-based therapy.
