RESUMO

Objective:To investigate the effects and mechanisms of interleukin-22(IL-22) on inhibiting liver fibrosis induced by HSC,and explore the role of Wnt/β-catenin pathway in the activation of hepatic stellate cells(HSC).Methods:Rat HSC was activated by TGF-β1,and the mRNA and protein levels of β-catenin and α-SMA were detected by q-PCR and Western blot,respectively.HSC was treated with different hours and concentration of recombinant rat protein IL-22.The cell proliferation rates were detected by CCK8,cell apoptosis rates were tested by flow cytometry.HSC were treated with optimal concentration of IL-22 after activated by TGF-β1,the cell proliferation rates,mRNA and protein levels of β-catenin and α-SMA were compared of before and after intervention.Results:The mRNA and the protein levels of β-catenin and α-SMA were significantly increased after activated by TGF-β1(P0.05).IL-22 significantly inhibited the activation of HSC induced by TGF-β1 and remarkably decreased the mRNA and the protein expression level of β-catenin and α-SMA(P<0.05).Conclusion:The Wnt/β-catenin pathway may participates in the process of HSC activation and α-SMA secretion,and IL-22 inhibits biological function of HSC in a dose-and time-dependent manner.This effect probably via inhibited the Wnt/β-catenin signal pathway.

RESUMO

Objective To evaluate the safety and efficacy of endoscopic ultrasonography(EUS) guided ethanol ablation in patients with insulinoma. Methods The data of 10 patients with insulinoma trea-ted at the First Affiliated Hospital of Guangxi Medical University from December 2013 to January 2015 were prospectively analyzed. Results The patients were given EUS-guided ethanol ablation with dose of 0. 10 to 2. 00 ml(average 0. 70 ± 0. 62 ml)in pancreatic lesions for 15 times. No complications were observed dur-ing and after the procedure. The blood glucose improved after the procedure[4. 8(3. 9-5. 5)mmol/ L VS 2. 4 (1. 9-2. 5)mmol/ L,P < 0. 05]and the serum insulin level significantly decreased[83. 7(40. 1-143. 5) pmol/ L VS 177. 3(66. 5-200. 6)pmol/ L,P<0. 05]. The average hospital stay was(4. 3±1. 5)days. The patients were followed up for 6-12 months. EUS indicated that the echo of pancreatic lesions changed from high to low. CE-EUS revealed low enhancement and lack of blood supply. Conclusion EUS-guided ethanol ablation may become a promising minimally invasive treatment for insulinoma because of its safety,efficacy and low price.

RESUMO

Objective To perform the bibliometric research on the literatures of the endoscopic retrograde cholangio pancreatog-raphy(ERCP) in the last ten years to provide reference for accurately grasping the international research situation and selecting the cutting-edge technological topics .Methods The literatures of ERCP in the database Web of Science from 2001 to 2011 were collect-ed .The CiteSpace software was adopted to analyze the distribution characteristics ,key point literature ,hotspots fields and research frontier of articles of ERCP .Results 2 921 citations of the research articles were retrieved .The analysis showed that America was strongest in the ERCP research field ;10 key point articles were detected .The high frequency keywords were complications ,manage-ment ,sphincterotomy ,etc .,the concentricity ranged 0 .06-0 .24 .The high frequency burst words were gold standard ,procedure-re-lated-complications ,biliary-stents ,but the concentricity was 0 .Conclusion The research hotspots of ERCP field are the occurrence rate of ERCP postoperative complications ,diagnosis and treatment ,but no obvious research cutting-edge is formed .
