ABSTRACT

Purpose@#Oxidized cellulose is available in many forms, but manufactured using either a regenerated or non-regenerated process. In this study, we evaluated the effects of 2 different hemostatic agents for the treatment of local bleeding in patients undergoing hepatic resection. @*Methods@#This was a monocentric, parallel-group, randomized, and controlled clinical trial to compare oxidized regenerated cellulose gauze (ORCG) with oxidized non-regenerated cellulose gauze (ONRCG) in patients undergoing hepatectomy. The primary endpoint was the time to hemostasis at the target bleeding site. The secondary endpoints were the postoperative drainage volume on the first 2 days after surgery and the hospital stay. @*Results@#There was no significant difference between the ORCG and ONRCG groups in time to hemostasis from column analysis (238.8 ± 121.6 seconds vs. 193.7 ± 85.3 seconds, P = 0.068), and there were no differences in the rates of hemostatic success between the 2 groups at 120 seconds (18.4% vs. 24.3%; odds ratio [OR], 0.703; 95% confidence interval [CI], 0.231–2.136) and 300 seconds (71.1% vs. 89.2%; OR, 0.298; 95% CI, 0.085–1.041). However, the ONRCG group was superior to the ORCG group in hemostasis according to the survival analysis (log-rank test, P = 0.044). Moreover, there were also no significant differences between the 2 groups in postoperative drainage volume on the first 2 days (P = 0.436, P = 0.381) and hospital stay (P = 0.537, P = 0.200). @*Conclusion@#ONRCG was not inferior to ORCG as a hemostatic agent in patients undergoing liver resection.

ABSTRACT

Objective To investigate the protective effect of FLPNF and the improvement of glucose-stimulated insulin secretion against dexamethasone-induced apoptosis of islet cells. Methods INS-1 cells were treated with oligopeptide FLPNF and dexamethasone, either separately or in combination. Proliferation of INS-1 cells in each group was assessed with CCK-8 assay and the insulin secretion stimulated by glucose was detected by ELISA. The apoptotic condition of the cells was observed and assessed with TUNEL and the apoptosis rate of each group was detected using flow cytometry. The expression of major target protein molecules related to apoptosis and Glut2 was detected by Western blotting analysis. Results Dexamethasone inhibited the growth of INS-1 cells in the group treated with dexamethasone. Cell damage was obvious with observable nuclear shrinkage and nuclear rupture. In addition, apoptosis rate was found to be 40.6%±2.4%. The expression of the apoptosis-related protein Bcl-2 and Glut2 was significantly reduced, whereas that of Bax and caspase-3 was significantly increased. After the combined treatment of oligopeptide FLPNF and dexamethasone, the results were reversed, and the apoptosis rate declined to 27.2%±2.0% (P < 0.001), cell morphology was improved, and the expression of apoptosis-related protein molecules of islet cells and protein Glut2 was significantly improved. Conclusion FLPNF has the ability of protecting islet cells from dexamethasone-induced apoptosis and improving the glucose-stimulated insulin secretion of islet cells.

ABSTRACT

Objective To study the effects of ω-3 fatty acid on liver function in patients undergoing hepatectomy. Methods A PubMed, Embase and Cochrane Library database search was performed to retrieve all of the randomized controlled trial (RCT) evaluating the value of perioperative ω-3 fatty acid in patients undergoing hepatectomy until the end of September 2016. Data extraction and quality assessment of RCT were performed in accordance with PRISMA guidelines. The quality of evidence for each postoperative outcome was assessed using the GRAD Profiler system. A random-effects model was used to conduct a Meta-analysis with RevMan 5.3.5 software. Results Five documents were identified according to the inclusion criteria. Meta- analysis results showed that ω- 3 fatty acid significantly reduced the levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) on the third day of the operation in patients undergoing hepatectomy: mean difference ( MD ) = -74.89 and-60.87, 95% CI-110.02?39.76 and-96.05?-25.68, P<0.01; ω-3 fatty acid significantly increased the level of prealbumin (Pre-Alb) on the third day of the operation: MD=9.61, 95% CI 4.22?15.00, P<0.01; but ω-3 fatty acid did not improve the levels of total bilirubin (TBil) and albumin (Alb) on the third day of the operation: MD=-1.13 and 1.16, 95% CI-2.48?0.21 and-0.35?2.68, P>0.05. Conclusions The ω-3 fatty acid is potentially beneficial in reducing the levels of ALT and AST, and increases the level of Pre-Alb on the third day of the operation in patients undergoing hepatectomy, but does not improve the levels of TBil and Alb.

ABSTRACT

Objective To investigate the expression characteristics of Golgi phosphoprotein 3(GOLPH3)in human hepatocellular carcinoma (HCC)and explore its clinicopathological significance. Methods The expressions of GOLPH3 protein was detected in 132 cases of paired paraf-fin embedded HCC specimens and pericarcinoma tissues using immunohistochemical staining ,and the relation of the expression of GOLPH3 to clinicopathologic features was analyzed. Meanwhile,the expression and distribution of GOLPH3 in HCC cells was observed by laser confocal mi-croscopy. Results The positive expression rates of GOLPH3 in HCC and pericarcinoma tissues were 70.0%(92/132)and 42.4%(56/132) (P<0.001),respectively. The incidence of portal vein tumor thrombus in high and low GOLPH3 expression groups of HCC were 21.2%(14/66) and 6.1%(4/66)(P<0.05),respectively. The expression rate of GOLPH3 in HCC was significantly higher than that in pericarcinoma tissues, and the expression of GOLPH3 in HCC was positively related to portal vein tumor thrombus. In addition ,GOLPH3 was mainly expressed in cyto-plasm of HCC cells,and there was also scattered distribution in the nucleus. Conclusion GOLPH3 acts as an oncogene and may play vital roles in the carcinogenesis and development of HCC.

ABSTRACT

Objective To explore the influence of abnormal donor hepatic artery on hepatic artery and biliary complications after liver transplanta?tion,and summarize the hepatic artery reconstruction procedures during transplantation. Methods The clinical data of 210 cases of liver transplan?tation conducted in our hospital from May 2005 to April 2015 were retrospectively searched for the study,including 42 with abnormal donor hepatic artery. Results Among the 210 liver transplantation,42 cases exhibited abnormal donor hepatic artery,and the aberration rate was 20.0%. Mean volume of blood flow of abnormal group and normal group was 4.7±95.1 mL/min and 190.9±101.6 mL/min,respectively. There was no statistic differ?ence(P=0.519). Twelve cases had arterial complications,the incidence rate was 5.71%,and there was no statistic difference between each group (χ2=0.72,P>0.05). Twenty five cases got biliary complications,the incidence rate was 11.9%,and there was no statistic differences between each group(χ2=0.05,P>0.05). Conclusion There was no statistic difference of mean volume of blood flow after arterial reconstruction between two groups. Liver transplantation with abnormal arterial reconstruction will not increase the incidence rate of arterial and biliary complications.
