| 1 | Biliary complications in liver transplantation: Impact of anastomotic technique and ischemic time on short- and long-term outcome显示文摘AIM: To elucidate the impact of various donor recipient and transplant factors on the development of biliary complications after liver transplantation.METHODS: We retrospectively reviewed 200 patients of our newly established liver transplantation(LT) program, who received full size liver graft. Biliary reconstruction was performed by side-to-side(SS), end-to-end(EE) anastomosis or hepeaticojejunostomy(HJ). Biliary complications(BC), anastomotic stenosis, bile leak, papillary stenosis, biliary drain complication, ischemic type biliary lesion(ITBL) were evaluated by studying patient records, corresponding radiologic imaging and reports of interventional procedures [e.g., endoscopic retrograde cholangiopancreatography(ERCP)]. Laboratory results included alanine aminotransferase(ALT), gammaglutamyltransferase and direct/indirect bilirubin with focus on the first and fifth postoperative day, six weeks after LT. The routinely employed external bile drain was examined by a routine cholangiography on the fifth postoperative day and six weeks after transplantation as a standard procedure, but also whenever clinically indicated. If necessary, interventional(e.g., ERCP) or surgical therapy was performed. In case of biliary complication, patients were selected, assigned to different complication-groups and subsequently reviewed in detail. To evaluate the patients outcome, we focussed on appearance of postoperative/post-interventional cholangitis, need for rehospitalisation, retransplantation, ITBL or death caused by BC.RESULTS: A total of 200 patients [age: 56(19-72), alcoholic cirrhosis: n = 64(32%), hepatocellular carcinoma: n = 40(20%), acute liver failure: n = 23(11.5%), cryptogenic cirrhosis: n = 22(11%), hepatitis B virus /hepatitis C virus cirrhosis: n = 13(6.5%), primary sclerosing cholangitis: n = 13(6.5%), others: n = 25(12.5%) were included. The median follow-up was 27 mo until June 2015. The overall biliary complication rate was 37.5%(n = 75) with anastomotic strictures(AS): n = 38(19%), bile leak(BL): n = 12(6%), biliary drain complication: n = 12(6%); papillary stenosis(PS): n = 7(3.5%), ITBL: n = 6(3%). Clinically relevant were only 19%(n = 38). We established a comprehensive classification for AS with four grades according to clinical relevance. The reconstruction techniques [SS: n = 164, EE: n = 18, HJ: n = 18] showed no significant impact on the development of BCs in general(all n < 0.05), whereas in the HJ group significantly less AS were found(P = 0.031). The length of donor intensive care unit stay over 6 d had a significant influence on BC development(P = 0.007, HR = 2.85; 95%CI: 1.33-6.08) in the binary logistic regression model, whereas other reviewed variables had not [warm ischemic time > 45 min(P = 0.543), cold ischemic time > 10 h(P = 0.114), ALT init > 1500 U/L(P = 0.631), bilirubin init > 5 mg/d L(P = 0.595), donor age > 65(P = 0.244), donor sex(P = 0.068), rescue organ(P = 0.971)]. 13%(n = 10) of BCs had no therapeutic consequences, 36%(n = 27) resulted in repeated lab control, 40%(n = 30) received ERCP and 11%(n = 8) surgical therapy. Fifteen(7.5%) patients developed cholangitis [AS(n = 6), ITBL(n = 5), PS(n = 3), biliary lesion BL(n = 1)]. One patient developed ITBL twelve months after LT and subsequently needed retransplantation. Rehospitalisation rate was 10.5 %(n = 21) [AS(n = 11), ITBL(n = 5), PS(n = 3), BL(n = 1)] with intervention or reinterventional therapy as main reasons. Retransplantation was performed in 5(2.5%) patients [ITBL(n = 1), acute liver injury(ALI) by organ rejection(n = 3), ALI by occlusion of hepatic artery(n = 1)]. In total 21(10.5%) patients died within the follow-up period. Out of these, one patient with AS developed severe fatal chologenic sepsis after ERCP.CONCLUSION: In our data biliary reconstruction technique and ischemic times seem to have little impact on the development of BCs. | Stefan Kienlein Wenzel Schoening Anne Andert Daniela Kroy Ulf Peter Neumann Maximilian Schmeding | 2015 | World Journal of Transplantation2015，5，4： | 14 |

| 3 | Treatment of Budd-Chiari syndrome with a focus on transjugular intrahepatic portosystemic shunt显示文摘AIM:To evaluate long-term complications and survival in patients with Budd-Chiari syndrome (BCS) referred to a Danish transjugular intrahepatic portosystemic shunt (TIPS) centre.METHODS:Twenty-one consecutive patients from 1997-2008 were retrospectively included [15 women and 6 men,median age 40 years (range 17-66 years)].Eighteen Danish patients came from the 1.8 million catchment population of Aarhus University Hospital and three patients were referred from Scandinavian hospitals.Management consisted of tests for underlying haematological,endocrinological,or hypercoagulative disorders parallel to initiation of specific treatment of BCS.RESULTS:BCS was mainly caused by thrombophilic (33%) or myeloproliferative (19%) disorders.Fortythree percents had symptoms for less than one week with ascites as the most prevalent finding.Fourteen (67%) were treated with TIPS and 7 (33%) were manageable with treatment of the underlying condition and diuretics.The median follow-up time for the TIPS-treated patients was 50 mo (range 15-117 mo),and none required subsequent liver transplantation.Ascites control was achieved in all TIPS patients with a marked reduction in the dose of diuretics.A total of 14 TIPS revisions were needed,mostly of uncovered stents.Two died during follow-up:One non-TIPS patient worsened after 6 mo and died in relation to transplantation,and one TIPS patient died 4 years after the TIPS-procedure,unrelated to BCS.CONCLUSION:In our BCS cohort TIPS-treated patients have near-complete survival,reduced need for diuretics and compared to historical data a reduced need for liver transplantation. | Anders Bay Neumann Stine Degn Andersen Dennis Tφnner Nielsen Peter Holland-Fischer Hendrik Vilstrup Henning Grφnbk | 2013 | World Journal of Hepatology2013，5，1： | 5 |
| 4 | Isolation and Expression Analysis of Two Genes Encoding Cinnamate 4-Hydroxylase from Cotton(Gossypium hirsutum)显示文摘Two genes(GhC4H1 and GhC4H2) that encode putative cotton cinnamate 4-hydroxylases that catalyze the second step in the phenylpropanoid pathway were isolated from developing cotton fibers. GhC4H1 and GhC4H2 each contain open reading frames of 1 518 base pairs(bp) in length and both encode proteins consisting of 505 amino acid residues. They are 90.89% identical to each other at the amino acid sequence level and belong to class I of plant C4 Hs. GhC4H1 and GhC4H2 genomic DNA are 2 247 and 2 161 bp long, respectively, and contain two introns located at conserved positions relative to the coding sequence. GhC4H1 and GhC4H2 promoters were isolated and found to contain many cis-elements(boxes P, L and AC-I element) previously identified in the promoters of other phenylpropanoid pathway genes. Histochemical staining showed GUS expression driven by the GhC4H1 and GhC4H2 promoters in ovules and fibers tissues. GhC4H1 and GhC4H2 were also widely expressed in other cotton tissues. GhC4H2 expression reached its highest level during the elongation stage of fiber development, whereas GhC4H1 expression increased during the secondary wall development period in cotton fibers. Our results contribute to a better understanding of the biochemical role of GhC4H1 and GhC4H2 in cotton fiber development. | NI Zhi-yong LI Bo Neumann M Peter Lü Meng FAN Ling | 2014 | Journal of Integrative Agriculture2014，13，10： | 3 |

| 14 | Reduced expression of Ca^(2+)-regulating proteins in the upper gastrointestinal tract of patients with achalasia显示文摘AIM: To compare expression of Ca2+-regulating proteins in upper gastrointestinal (GI) tract of achalasia patients and healthy volunteers and to elucidate their role in achalasia. METHODS: Sarcoplasmic reticulum Ca2+ ATPase (SERCA) isoforms 2a and 2b, phospholamban (PLB), calsequestrin (CSQ), and calreticulin (CRT) were assessed by quantitative Western blotting in esophagus and heart of rats, rabbits, and humans. Furthermore, expression profi les of these proteins in biopsies of lower esophageal sphincter and esophagus from patients with achalasia and healthy volunteers were analyzed. RESULTS: SERCA 2a protein expression was much higher in human heart (cardiac ventricle) compared to esophagus. However, SERCA 2b was expressed predominantly in the esophagus. The highest CRT expression was noted in the human esophagus, while PLB, although highly expressed in the heart, was below our detection limit in upper GI tissue. Compared to healthy controls, CSQ and CRT expression in lower esophageal sphincter and distal esophageal body were signif icantly reduced in patients with achalasia (P < 0.05). CONCLUSION: PLB in the human esophagus mightbe of lesser importance for regulation of SERCA than in heart. Lower expression of Ca2+ storage proteins (CSQ and CRT) might contribute to increased lower esophageal sphincter pressure in achalasia, possibly by increasing free intracellular Ca2+. | Harald Fischer Judith Fischer Peter Boknik Ulrich Gergs Wilhelm Schmitz Wolfram Domschke Jan W Konturek Joachim Neumann | 2006 | World Journal of Gastroenterology2006，12，37： | 1 |
