| 1 | Efficacy and safety of tenofovir disoproxil fumarate in pregnancy for the prevention of vertical transmission of HBV infection显示文摘AIM:To evaluate the effects of tenofovir disoproxil fumarate(TDF)use during late pregnancy to reduce hepatitis B virus(HBV)transmission in highly viremic mothers.METHODS:This retrospective study included 45 pregnant patients with hepatitis B e antigen(+)chronic hepatitis B and HBV DNA levels>107copies/mL who received TDF 300 mg/d from week 18 to 27 of gestation(n=21).Untreated pregnant patients served as controls(n =24).All infants received 200 IU of hepatitis B immune globulin(HBIG)within 24 h postpartum and 20μg of recombinant HBV vaccine at 4,8,and 24 wk.Perinatal transmission rate was determined by hepatitis B surface antigen and HBV DNA results in infants at week 28.RESULTS:At week 28,none of the infants of TDFtreated mothers had immunoprophylaxis failure,whereas2(8.3%)of the infants of control mothers had immunoprophylaxis failure(P=0.022).There were no differences between the groups in terms of adverse events in mothers or congenital deformities,gestational age,height,or weight in infants.At postpartum week 28,significantly more TDF-treated mothers had levels of HBV DNA<250 copies/mL and normalized alanine aminotransferase compared with controls(62%vs none,P<0.001;82%vs 61%,P=0.012,respectively).CONCLUSION:TDF therapy during the second or third trimester reduced perinatal transmission rates of HBV and no adverse events were observed in mothers or infants. | Mustafa Kemal Celen Duygu Mert Müzeyyen Ay Tuba Dal Safak Kaya Necmettin Yildirim Serda Gulsun Tunga Barcin Sevgi Kalkanli Mehmet Sinan Dal Celal Ayaz | 2013 | World Journal of Gastroenterology2013，19，48： | 26 |
| 2 | Toll-like receptors in pathophysiology of liver diseases显示文摘Toll-like receptors(TLRs) are pattern recognition receptors that participate in host defense by recognizing pathogen-associated molecular patterns alongside inflammatory processes by recognizing damage associated molecular patterns. Given constant exposure to pathogens from gut, strict control of TLR-associated signaling pathways is essential in the liver, which otherwise may lead to inappropriate production of pro-inflammatory cytokines and interferons and may generate a predisposition to several autoimmune and chronic inflammatory diseases. The liver is considered to be a site of tolerance induction rather than immunity induction, with specificity in hepatic cell functions and distribution of TLR. Recent data emphasize significant contribution of TLR signaling in chronic liver diseases via complex immune responses mediating hepatocyte(i.e., hepatocellular injury and regeneration) or hepatic stellate cell(i.e., fibrosis and cirrhosis) inflammatory or immune pathologies. Herein, we review the available data on TLR signaling, hepatic expression of TLRs and associated ligands, as well as the contribution of TLRs to the pathophysiology of hepatic diseases. | Safak Kiziltas | 2016 | World Journal of Hepatology2016，8，32： | 25 |
| 3 | Matched-pair analysis of postoperative morbidity and mortality for pancreaticogastrostomy and pancreaticojejunostomy using mattress sutures in soft pancreatic tissue remnants显示文摘BACKGROUND:After pancreaticoduodenectomy,the incidence of postoperative pancreatic fistula remains high,especially in patients with 'soft' pancreatic tissue remnants.No 'gold standard' surgical technique for pancreaticoenteric anastomosis has been established.This study aimed to compare the postoperative morbidity and mortality of pancreaticogastrostomy and pancreaticojejunostomy for 'soft' pancreatic tissue remnants using modified mattress sutures.METHODS:Seventy-five patients who had undergone pancreaticogastrostomy and 75 who had undergone pancreaticojejunostomy after pancreaticoduodenectomy between 2002 and 2008 were retrospectively compared using matched-pair analysis.A modified mattress suture technique was used for the pancreaticoenteric anastomosis.Patients with an underlying 'hard' pancreatic tissue remnant,as in chronic pancreatitis,were excluded.Both groups were homogeneous for age,gender,and underlying disease.Postoperative morbidity,mortality,and preoperative and operative data were analyzed.RESULTS:There were no significant differences between the groups for the incidence of postoperative pancreatic fistula (10.7% in both).Postoperative morbidity and mortality,median operation time,median length of hospital stay,intraoperative blood loss,and the amount of intraoperatively transfused erythrocyte concentrates also did not significantly differ between the groups.Patient age >65 years (P=0.017),operation time >350minutes (P=0.001),and intraoperative transfusion of erythrocyte concentrates (P=0.038) were identified as risk factors for postoperative morbidity.CONCLUSIONS:Our results showed no significant differences between the groups in the pancreaticogastrostomy and pancreaticojejunostomy anastomosis techniques using mattress sutures for 'soft' pancreatic tissue remnants.In our experience,the mattress sutures are safe and simple to use,and pancreaticogastrostomy in particular is feasible and easy to learn,with good endoscopic accessibility to the anastomosis region.However,the location of the anastomosis and the surgical technique need to be individually evaluated to further reduce the incidence of postoperative pancreatic fistula. | Fritz Klein Marcus Bahra Matthias Glanemann Wladimir Faber Peter Warnick Andreas Andreou Safak Gül Dietmar Jacob | 2012 | Hepatobiliary & Pancreatic Diseases International2012，11，1： | 9 |
| 4 | Trabeculectomy with large area mitomycin-C application as a first-line treatment in advanced glaucoma: retrospective review显示文摘AIM: To evaluate the outcomes of trabeculectomy with large area mitomycin-C(MMC) application as a first line treatment in advanced glaucoma. ·METHODS: The records of 55 patients with severe visual field defects undergoing trabeculectomy were retrospectively reviewed. The patients were classified as first-line therapy to either early trabeculectomy(initial trabeculectomy-Group 1) or long term medical therapy followed by trabeculectomy(primary trabeculectomy-Group 2). Trabeculectomy was performed with large-area MMC application. Intraocular pressure(IOP) values,visual acuities,mean deviations,morphology and function of the blebs,necessity for anti-glaucomatous medications and surgical complications were reported. ·RESULTS: There were 20 eyes of 18 patients in Group 1 and 37 eyes of 37 patients in Group 2. The mean preoperative IOPs in Groups 1 and 2 were 40.2±10.0mmHg(27-68mmHg) and 29.0±4.4mmHg(21-41mmHg),respectively(P=0.001). Average preoperative mean deviations(MD) in Groups 1 and 2 were 17.4±2.8dB(13.3-23dB) and 17.9± 2.4dB(13.7-23.2dB),respectively(P=0.441). Postoperative IOPs significantly decreased and were comparable in both Groups. The mean number of medications was significantly higher in Group 2(P =0.005). No cystic bleb formation was observed in Group 1,whereas 4 patients from Group 2(10.8%) developed cystic bleb(P =0.040). No visually devastating complication has occurred in both Groups. ·CONCLUSION: Initial trabeculectomy with large areaMMC application might be applied in patients with advanced glaucoma with low complication rates. Long-term topically applied anti-glaucomatous medications seem to increase the risk of cystic bleb formation. | Zeynep Aktas Safak Korkmaz Murat Hasanreisoglu Merih Onol Berati Hasanreisoglu | 2014 | International Journal of Ophthalmology(English edition)2014，7，1： | 6 |
| 5 | Effect of Helicobacter pylori eradication on serum ghrelin and obestatin levels显示文摘AIM: To investigate changes in serum ghrelin and obestatin levels before and after Helicobacter pylori (H. pylori ) eradication. METHODS: A total of 92 patients presenting with symptoms of dyspepsia were enrolled in the study. Upper endoscopy was performed on all patients and used to diagnose H. pylori infection according to the presence of characteristic histopathological findings; seventy patients were diagnosed with H. pylori infection and the remaining 22 non-infected patients were classified as healthy controls. H. pylori eradication was accomplished by administering the classical triple therapy drug regimen, consisting of lansoprazole 30 mg bid , amoxicillin 1 g bid , and clarithromycin 500 mg tid for 14 d. The eradication of H. pylori was assessed with C14-urea breath test, which was performed at eight weeks after treatment. Levels of serum active ghrelin and obestatin were assessed at beginning of the study (prior to treatment) and after eight weeks. The levels were comparatively analyzed between the H. pylori negative control group, the H. pylori eradicated group, and the H. pylori non-eradicated group. RESULTS: A total of 92 patients, 50 females and 42 males with a mean age of 38.2 ± 11.9 years (range: 19-64), were analyzed. H. pylori eradication success was achieved in 74.3% (52/70) of H. pylori positive patients. The initial levels of ghrelin in the H. pylori positive and control cases were 63.6 ± 19.8 pg/mL and 65.1 ± 19.2 pg/mL (P=0.78), respectively, and initial obestatin levels were 771±427 pg/mL and 830 ± 296 pg/mL (P=0.19), respectively. The difference between the initial levels and the week 8 levels of ghrelin and obestatin in the control group was insignificant [4.5% (P=0.30) and -0.9% (P=0.65), respectively]. The difference between the initial and week 8 levels of ghrelin and obestatin in the H. pylori non-eradicated group were also insignificant [0.9% (P=0.64) and 5.3% (P=0.32), respectively]. The H. pylori eradicated group had a greater change in obestatin levels when compared to the control and the non-eradicated groups (148 ± 381 pg/mL vs -12±138 pg/mL and -72.8±203 pg/mL, respectively, P=0.015), while decreases in ghrelin levels were insignificant (-7.2 pg/mL vs -1.4 pg/mL and -1.9 pg/mL, respectively, P=0.52). The ghrelin/obestatin ratio for the initial and week 8 levels changed significantly in only the H. pylori eradicated group (0.11 vs 0.08, respectively, P=0.015). For overweight patients (as designated by body mass index), we observed significant increases in obestatin levels in the eradicated group as compared to non-eradicated group (201 ± 458 pg/mL vs -5 ± 81 pg/mL, respectively, P=0.02). In the H. pylori-eradicated group, the levels did not differ between the sexes for ghrelin (-6.3 ± 26.9 pg/mL vs -8.0 ± 24.0 pg/mL, respectively, P=0.97) or obestatin (210 ± 390 pg/mL vs 96 ± 372 pg/mL, respectively, P=0.23).CONCLUSION: Serum levels of ghrelin decreased while obestatin levels increased in H. pylori eradicated subjects, especially in overweight and male patients. | Celal Ulasoglu Banu Isbilen Levent Doganay Filiz Ozen Safak Kiziltas Ilyas Tuncer | 2013 | World Journal of Gastroenterology2013，19，15： | 5 |
