AIM: To eval.ate the thickness and vol.me changes of the choroidal. outer retinal.l.yers(ORl. and retinal.p.gment ep.thel.um(Rp.) in p.tients with diabetic retinop.thy(DR) using op.ical.coherence tomograp.y(OCT) and correl.te them with visual.***: We carried out a retrosp.ctive observational.case series. Consecutive DR p.tients were recruited for col.r fundus p.otograp.y and OCT assessment. The Rp., ORl.and choroidal.thickness were measured. The correl.tion with the best-corrected visual.acuity(BCVA) was al.o ***: The study incl.ded 128 eyes, comp.ising 45 eyes of 25 diabetic macul.r edema(DME) p.tients, 34 eyes of 20 DR without DME(non-DME) p.tients, and 49 eyes of 25 age-matched normal.individual.. The choroidal.thickness in DR p.tients were decreased statistical.y significantl. comp.red with the control.group.p.0.05). The mean macul.r ORl.thickness in DME(73.02±15.34 μm) and non-DME group.(76.35±7.32 μm) were decreased statistical.y significantl. comp.red with the control.group.80.20±5.85 μm; p.0.006, p.0.013, resp.ctivel.). In both the non-DME and DME group., the Rp. thickness were decreased comp.red with the control.group.p.0.05), excep. in the macul.r and central.ring. The BCVA were significant interactions with the total.inner retinal.vol.me and macul.r Rp. thickness in the DME group.r=0.115, p.0.001, r=-0.013, p.0.017, resp.ctivel.).CONCl.SION: The choroid, ORl.and Rp. thickness are significantl. decreased in DR p.tients comp.red with control. in different segments.

This study is undertaken to ap.l. a bootstrap.method of control.ing the fal.e discovery rate （FDR） when p.rforming p.irwise comp.risons of normal.means. Due to the dep.ndency of test statistics in p.irwise comp.risons, many conventional.mul.ip.e testing p.ocedures can＇t be emp.oyed directl.. Some modified p.o- cedures that control.FDR with dep.ndent test statistics are too conservative. In the p.p.r, by bootstrap.and goodness-of-fit methods, we p.oduce indep.ndent p.val.es for p.irwise comp.risons. Based on these indep.n- dent p.val.es, p.enty of p.ocedures can be used, and two typ.cal.FDR control.ing p.ocedures are ap.l.ed here. An examp.e is p.ovided to il.ustrate the p.op.sed ap.roach. Extensive simul.tions show the satisfactory FDR control.and p.wer p.rformance of our ap.roach. In addition, the p.op.sed ap.roach can be easil. extended to more than two normal. or non-normal. bal.nce or unbal.nce cases.

In this p.p.r,we consider a cl.ss of fractional.p.obl.m with subcritical.p.rturbation on a bounded domain as fol.ows:(p.(k)){(−△)^(s)u = g(x)[(u − k)+]^(q−1) +u^(2^(∗)_(s)−1), x ∈Ω ,u > 0, x∈Ω ,u = 0, x ∈Ω R^(N)\Ω. We p.ove the existence of nontrivial.sol.tions u_(k) of(p.(k))for each k∈(0,∞).We al.o investigate the concentration behavior of the sol.tions u_(k) as k→∞.

作者： Da-Wei l. Bao-Zhong Wu Yu-Sen Shi Zhi-Qun l. Xu-Dong l.u Xiao-Hua l. Radiol.gy Dep.rtment Affiliated Hospital of Hainan Medical College

Objective: To study the association of CT p.rfusion imaging p.rameters with p.asma l.vel.of transforming growth factor-β1(TGF-β1) and vascul.r endothel.al.growth(VEGF) in p.tients with non smal. cel. cancer(NSCl.). Methods: A total.of 67 p.tients with NSCl.(NSCl. group. and 64 p.tients with benign l.sion(control.group. were given with CT p.rfusion imaging to obtain bl.od fl.w, bl.od vol.me, mean transit time, time to p.al.and p.rmeabil.ty surface through CT p.rfusion software. The p.asma l.vel. of TGF-β1 and VEGF were tested by El.SA. The rel.tionship.between p.asma l.vel. of TGF-β1, VEGF and CT p.rfusion imaging p.rameters were anal.zed. Resul.s: CT p.rfusion imaging p.rameters and the p.asma l.vel. of TGF-β1 and VEGF of NSCl. group.were significantl. higher than the control.group.p.0.05), whil. CT p.rfusion p.rameters and the l.vel. of TGF-β1 and VEGF in NSCl. group.showed significant difference in different tumor node metastasis stages(p.0.05). Correl.tion anal.sis showed that the l.vel.of p.asma TGF-β1 and VEGF were p.sitivel. correl.ted with bl.od fl.w, bl.od vol.me, and mean transit time(p.0.05), and negativel. correl.ted with time to p.al.p.0.05). There was no significant correl.tion between TGF-β1 and VEGF with the p.rmeabil.ty surface. Concl.sions: CT p.rfusion imaging p.rameters in p.tients with NSCl. is cl.sel. associated with p.asma TGF-β1, VEGF and its biol.gical.characteristics. CT p.rfusion imaging is a convenient method to detect tumor bl.od p.rfusion.
