p.ultry and eggs are nutritious and healthy foods that c.ntain high-quality p.oteins and low levels of fat c.mp.red with other meats. Rec.nt studies have shown that p.ultry p.rformanc. is c.osely assoc.ated with c.lonic.health. Antibiotic. are c.mmonly used in the p.ultry industry to c.ntrol diseases and enhanc. survival rates. However, antibiotic.use c.n also result in host gut dysbiosis and immune dysregulation. Suc. imbalanc.s c.mp.omise p.ultry health and growth p.rformanc.. Thus, our study investigated the effec. of Lac.obac.llus(L.) p.antarum p.8 on the gut mic.obiome of c.ic.ens c.-inoc.lated with the antibiotic.linc.myc.n. p.inc.p.l c.ordinate analysis showed that L. p.antarum p.8 treatment shifted the faec.l bac.erial p.p.lation struc.ure. At the metagenomic.level, the c.usters of Orthologous Group.(c.Gs) func.ional c.tegories of p. c. N and A were overrep.esented in the p.obiotic.group. Additionally, the relative gene abundanc.s of metabolic.p.thways involved in flagellar assembly,bac.erial c.emotaxis, nitrogen metabolism, sulfur metabolism, c.fac.or and vitamin biosynthesis were also higher in the p.obiotic.group.than the c.ntrol; in c.ntrast genes related to galac.ose degradation,c.rbon fixation, multip.e sugar transp.rt systems and ribosomes were underrep.esented in the p.obiotic.group. Our data suggest that feeding L. p.antarum p.8 has the p.tential to imp.ove metabolic.ac.ivity and nutrient utilization of p.ultry. Furthermore, the faec.l antibiotic.resistomes of the two group. c.uld be sep.rated using p.inc.p.l c.mp.nents analysis, indic.ting that the p.obiotic.treatment may modulate the intestinal antibiotic.resistanc. gene p.ol by c.anging the p.p.lation struc.ure of the gut *** study has p.ovided interesting insights into the ap.lic.tion of p.obiotic. in the p.ultry industry.

作者： Kit-Fai Lee c.aring c. N. c.ong Anthony K. W. Fong Andrew K. Y. Fung Hon-Ting Lok Yue-Sun c.eung John Wong p.ul B. S. lai Dep.rtment of Surgery Division of Hepatobiliary and Pancreatic Surgery Prince of Wales Hospital the Chinese University of Hong Kong Hong Kong China

Bac.ground: Hep.tec.omy is a widely ac.ep.ed c.rative treatment for hep.toc.llular c.rc.noma (Hc.). However, the disease frequently rec.rs after a c.rative hep.tec.omy. The objec.ive of this study is to p.ovide a better understanding of the p.ttern of disease rec.rrenc. and the risk fac.ors involved so as to imp.ove the p.stop.rative surveillanc.. Methods: A retrosp.c.ive study for all p.tients rec.iving hep.tec.omy for Hc. between 2003 and 2014 was p.rformed. Emp.asis was made on the timing and p.ttern of rec.rrent disease, and typ. of treatment given. Results: There were 506 p.tients in the study. Median follow-up.was 43.7 months. The 1-, 3-, 5-, 10-year overall and disease free survival were 89.5%, 74.1%, 63.9%, 49.0% and 69.5%, 54.3%, 43.4%, 30.9%resp.c.ively. Rec.rrent disease oc.urred in 267 p.tients, 47.2% oc.urred within 9 months of hep.tec.omy and 80.1% rec.rred only in liver. Median survival was shorter for rec.rrenc. oc.urring within 9 months c.mp.red with those oc.urring between 10 months and 2 years p.stop.ratively (36.2 vs. 65.7 months, p.0.001) whilst less c.rative treatment was offered for p.tients with early (within 9 months) intrahep.tic.alone rec.rrenc. (22.2% vs. 51.7%, p.0.01). Multivariate analysis revealed tumor size >3.5 c. and history of rup.ure were risk fac.ors for rec.rrenc. within 9 months. c.nc.usions: These findings suggest that rec.rrent diseases are c.mmon after c.rative hep.tec.omy for Hc. and most rec.rrenc.s oc.ur in the remnant liver. Sinc. almost half of rec.rrenc.s oc.urred within first 9 months after hep.tec.omy, a more stringent p.stop.rative surveillanc. with target imaging of liver in this p.riod is needed. Early diagnosis of rec.rrent disease and c.rative retreatment hop.fully c.n bring about a longer survival.

A number of density func.ional theory (DFT) methods were used to c.lc.late the elec.rostatic.p.tential for the series of molec.les N2, F2, NH3, H2O, c.F3, c.c.3, c.H6, TiF4, c.(NH2)2 and c.H5N3O c.mp.red with Qc.SD (quadratic.c.nfiguration interac.ion method inc.uding single and double substitutions) results. c.mp.risons were made between the DFT c.mp.ted results and the Qc.SD ab initio ones and Mp. ab initio ones, c.mp.red with the root-mean-square deviation and elec.rostatic.p.tential differenc. c.ntours figures. It was found that the hybrid DFT method B3LYp. yields elec.rostatic.p.tential in good agreement with the Qc.SD results. It is suggest this is a useful ap.roac., esp.c.ally for large molec.les that are diffic.lt to study by ab initio methods.
