Objective To investigate the effects of Liraglutide on plasma FGF-21 level in patients with type 2 diabetes mellitus (T2DM). Methods Enzyme linked immunosorbent assay (ELISA) was used to measure plasma FGF-21 level in patients with T2DM and normal controls (NGT). Relationship between plasma FGF-21level and BMI, WHR, HOMA-IR, HOMA-IS, FFA was analyzed. After Liraglutide treatment, plasma FGF-21level was observed in patients with T2DM. Results Fasting plasma FGF-21 level was higher in T2DM patients than that in normal control group ( 1.81 ±0.32 vs. 1.32 ±0.09 μg/L, P ＜0.01 ). After Liraglutide treatment, WHR, BMI, FPG, 2hPBG, HbA1c and FFA in T2DM patients significantly decreased ( P ＜0.05 or P ＜0. 01 ),HOMA-IS remarkably increased (P ＜ 0. 01 ), and FGF-21 had no change. Conclusion Liraglutide and FGF-21may have different roles in insulin resistance.

Objective To investigate the value of spiral CT in therapy observation during and after radiofrequency ablation (RFA) for lung or liver tumors. Methods Spiral CT-guided RFA were performed in 35 patients (38 lesions) with lung or liver tumors. CT value of lesions during operation and the changes of lesions after operation were observed. Results Thirty-eight lesions were accurately located under spiral CT. The position of the electrode and the expension of claw-like thin needle electrode could be observed directly. CT value of lesions decreased and some gasification foci in some lesions were observed after RAF therapy. One month after RFA, tumor volume decreased, and the tumors present as slightly low-density mass on contrast-enhanced CT. The total effective rate of RFA was 85.71% (30/35). Conclusion Spiral CT is able to accurately guide RFA treatment for lung or liver tumors and evaluate the efficacy of therapy.

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 impact of hepatitis B virus (HBV) infection on semen parameters,sperm DNA integrity,acrosin activity and sperm-nucleoprotein transition.Methods Semen samples from 527 subjects including 273 hepatitis B surface antigen (HBsAg) positive and 254 HBsAg negative,who sought medical attention and received in-vitro feritilization in reproductive medicine center of First Hospital of Wenzhou Medical University from Jan 2011 to Oct 2012 were collected.Semen parameters,sperm DNA fragmentation index (DFI),sperm-nucleoprotein transition and acrosin activity of both HBsAg-positive and HBsAg-negative subjects were analyzed.Results Semen parameters of both groups were within the normal range,but sperm concentration and percentage of forward moving sperms of HBsAg positive group were significantly lower than those of HBsAg negative group (P=0.000),while percentage of static sperms of HBsAg positive group were significantly higher than that of HBsAg negative group (P =0.000).DFI in HBsAg positive and negative group were (17.85 ± 0.70) ％ and (11.85 ± 0.50) ％,respectively,which was significantly different (t=6.951,P=0.000).Percentage of sperms with normal morphology in both groups were within the normal range,but sperms with neck and tail deformity in the HBsAg positive group was significantly higer than those in HBsAg negative group (all P＜0.05).Acrosin activity of sperms in HBsAg positive group was significantly lower than that in HBsAg negative group (t=3.756,P=0.000).Linear regression analysis indicated that serum HBsAg level was reversely correlated with sperm concentration (r=-0.140,P =0.021),but positively correlated to DFI (r =0.151,P =0.014).Conclusions HBV infection not only affects the routine semen parameters and sperm morphology,but also compromises sperm function including impaired DFI and acrosin activity.However,the impact of anti-HBV agents on sperm quality and male fertility requires further research.

Objective:This study aimed to explore the effect of Yes-associated protein (YAP) on the growth of the human glioma cell line LN229. Methods:YAPsiRNA was transfected into LN229 cells to knock down the YAP expression. The downregulation of the YAP expression was identified through Western Blot analysis. Colorimetric assay using methyl-thiazolyl-tetrazolium was applied to evaluate cell proliferation ability. Cell invasive activity was examined using Transwell assay. Flow cytometry and AnnexinV were used to detect cell cycle and apoptosis, respectively. The relevant molecules regulating proliferation, invasion, cell cycle progression, and apoptosis were examined through Western Blot analysis. Results:The YAP expression was downregulated after YAPsiRNA was trans-fected into LN229 glioma cells. Reduced YAP expression could arrest the cell cycle at G0/G1 phase, inhibit cell proliferation and inva-sion, and promote apoptosis. The expression of the proliferating cell nuclear antigen (Ki-67), matrix metallopeptidase-9 (MMP-9), cy-clin D1, and Bcl-2 were downregulated. Conclusion:The downregulation of YAP in LN229 cells suppresses cell proliferation and inva-sion, as well as promotes cell apoptosis. This study provides a novel evidence for further study on Hippo-YAP signal pathway in molec-ular pathology of glioma.

Objective To investigate the effect of knocking-down Yes-associated protein (YAP)on the biologi-cal characteristics of SNB19 glioblastoma cell.Methods The expression of YAB in SNB19 was knockdown by YAB small interfering RNA (YABsiRNA).The downregulation of YAP expression was identified by Western blot analysis. The proliferative ability of cell was determined by methyl thiazoyl terazolium (MTT).The invasive ability of cell was examined by Transwell assay.Flow cytometry and Annexin V staining were used to detect the cell cycle and apoptosis respectively.The results were analyzed by the statistical software SPSS18.0.Results The expression of YAP in the cells transfected with YAPsiRNA was significantly reduced.The cell proliferation activity of SNB19 cells was inhibited, which decreased from (100.00 ±0.00)%to (52.32 ±3.10)%(F=33.00,P<0.01).The cell cycle was arrested in G0-G1 phase (F=8.76,P<0.01).The cell invasive ability was attenuated apparently,which decreased from (163.20 ±10.10)to (37.71 ±2.52)(F=282.05,P<0.01).The apoptosis ratio of the tumor cell which transfected with YAPsi-RNA was increased from (3.56 ±0.35)%to (18.99 ±0.66)%,(F=931.99,P<0.01).Conclusion Knocking-down YAP expression in glioma cells could inhibit the proliferative activity and invasive ability of SNB19 cell and could induce cell apoptosis.YAP could be served as a potential target for the gene therapy of glioma.

Objective To study the inhibitory effect of knocking down miR-30a-5p on the U87 human glioma xenograft growth and its possible mechanism.Methods Nude mice bearing subcutaneous U87 human glioblastoma were established and separated into three groups (eight for each group) by randomized digital table method,including control group,scr-ODN treated group and AS-miR-30a-5p treated group.After relevant subcutaneous injection treatment,tumor size was measured every other day until the observation period ended.Researchers executed the animals after the treatment,stripped tumor tissues and extracted RNA and protein.Real-time PCR was conducted to detect the expression of miR-30a-5p.The histopathological characteristics and proliferation and apoptosis biological characters (including SEPT7,PCNA,cyclin D1,MMP-2,apoptosis related factor P53,bcl-2 and caspase3) were evaluated by HE and immunohistochemical staining,Westem blot analysis respectively,and the cell apoptosis was detected by TUNEL method.Results In AS-miR-30a-5p treated group,the tumor growth was delayed and the final tumor volume was smaller than that in the control and scr-ODN treated group (F =7.167,P ＜0.05),and the expression of miR-30a-5p was knocked down.The expression of PCNA,cyclin D1 were significantly downregulated while P53,SEPT7 and caspase3 up-regulated.Apoptotic index was increased significantly.Conclusion As-miR-30a-5p suppresses the growth of U87 human gliomas xenografts significantly.Malignant phenotype of tumors are reversed to a considerable degree.Therefore,miR-30a-5p can be a candidate for targeted therapy of human glioma.
