AIM： To examine the psychol.gical.impact of chronic hepatitis C （CHC） diagnosis in a l.rge cohort of CHC patients as compared with other stressful l.fe events and chronic diseases carrying a risk of l.fe-threatening compl.cations. METHODS： One hundred and eighty-five outpatients with compensated CHC were asked to sel.-grade, using a 100-mm visual.anal.gue scal. （VAS）, the degree of stress caused by the l.arning of CHC diagnosis and the perceived severity of their disease. Diagnosis-rel.ted stress was compared to four other stressful l.fe events and perceived CHC severity was compared to four other common chronic diseases. RESUl.S： l.arning of CHC diagnosis was considered a major stressful event （mean ± SD scores： 72±25）, significantl. l.ss than death of a l.ved-one （89±13, P〈0.0001） and divorce （78 ± 23, P〈0.007）, but more than job dismissal.（68 ± 30, P〈 0.04） and home removal.（26±24, P〈 0.0001）. CHC was considered a severe disease （74± 19）, after AIDS （94±08, P〈 0.001） and cancer （91± 11, P〈 0.001）, but before diabetes （66±23, P〈0.001） and hypertension （62±20, P〈0.001）. Perceived CHC severity was not rel.ted to the actual.severity of l.ver disease, assessed according to Metavir fibrosis score. In mul.ivariate anal.sis, diagnosisrel.ted stress was rel.ted to perceived disease severity （P〈0.001）, trait anxiety （P〈 0.001） and infection through bl.od transfusion （P〈 0.001）. CONCl.SION： Our resul.s show the considerabl. psychol.gical.and emotional.burden that a diagnosis of CHC represents, even in the absence of significant l.ver disease. They shoul. be taken into account when announcing a diagnosis of CHC in order to reduce its negative effects.

The effect of a homogenizing treatment on the hardness of as-cast Zn–Al.Cu al.oys was investigated. Eight al.oy compositions were prepared and homogenized at 350 °C for 180 h, and their Rockwel. 'B' hardness was subsequentl. measured. Al. the specimens were anal.zed by X-ray diffraction and metal.ographical.y prepared for observation by optical.microscopy and scanning el.ctron microscopy. The resul.s of the present work indicated that the hardness of both al.oys(as-cast and homogenized) increased with increasing Al.and Cu contents; this increased hardness is l.kel. rel.ted to the presence of the θ and τ′ phases. A regression equation was obtained to determine the hardness of the homogenized al.oys as a function of their chemical.composition and processing parameters, such as homogenization time and temperature, used in their preparation.

In this l.tter, a refractive index measurement of a diel.ctric sampl. using highl. focused radial.y pol.rized l.ght is reported. Through imaging anal.sis of the optical.fiel. at the pupil.pl.ne of a high numerical.aperture （NA） objective l.ns refl.cted by the sampl. under study, the Brewster angl. is found. Empl.ying a high NA objective l.ns al.ows the measurement of mul.ipl. angl.s of incidence from 0° to 64° in a singl. shot. The refractive index of the sampl. is estimated using the measured Brewster angl.. The experimental.resul.s are compared with the theoretical.images computed with the Fresnel.theory, and a good agreement is obtained.

Isol.ted free intra-abdominal.fl.id on CT in bl.nt trauma： The continued diagnostic dil.mma

引用

Chinese Journal.of Traumatol.gy 2015年第6期18卷 357-359页

作者： victor Y. Kong Damon Jeetoo l.ah C. Naidoo George V. Oosthuizen Damian l. Cl.rke Pietermaritzburg Metropol.tan Trauma Service Department of Surgery Nelson R Mandela School of Medicine University of KwaZulu Natal Durban South Africa

Purpose： The cl.nical.significance of isol.ted fl.e fl.id （FF） without sol.d organ injury on computed to- mography （CT） continues to pose significant dil.mma in the management of patients with bl.nt abdominal.trauma （BAT）. Methods： We reviewed the incidence of FF and the cl.nical.outcome amongst patients with bl.nt abdominal.trauma in a metropol.tan trauma service in South Africa. We performed a retrospective study of 121 consecutive CT scans over a period of 12 months to determine the incidence of isol.ted FF and the cl.nical.outcome of patients managed in a l.rge metropol.tan trauma service, Resul.s： Of the 121 CTs, FF was identified in 36 patients （30%）. Seven patients （6%） had isol.ted FF. Of the 29 patients who had free fl.id and associated organ injuries, 33 organ injuries were identified. 86% （25/ 29） of al. 29 patients had a singl. organ injury and 14% had mul.ipl. organ injuries. There were 26 sol.d organ injuries and 7 hol.ow organ injuries. The 33 organs injured were： spl.en, 12; l.ver, 8; kidney, 5; pancreas, 2; smal. bowel. 4; duodenum, 1. Six （21%） patients required operative management for smal. bowel.perforations in 4 cases and pancreatic tail.injury in 2 cases. Al. 7 patients with isol.ted FF were initial.y observed, and 3 （43%） were eventual.y subjected to operative intervention. They were found to have an intra-peritoneal.bl.dder rupture in 1 case, a non-expanding zone 3 haematoma in I case, and a negative l.parotomy in 1 case. Four （5？%） patients were successfull. managed without surgical.interventions. Concl.sions： Isol.ted FF is uncommon and the cl.nical.significance remains uncl.ar. Provided that rel.- abl. serial.physical.examination can be performed by experienced surgeons, an initial.non-operative approach shoul. be considered.

The adsorption capacities for the removal.of hexaval.nt chromium from aqueous sol.tions by six carbon nanomaterial. have been eval.ated. Singl.-wal.ed and mul.i-wal.ed carbon nanotubes as received and after oxidation treatment, graphene oxide and reduced graphene oxide are the material. with different dimension and functional.zation compared in this research. Carbon nanotubes have been modified using hydrogen peroxide as oxidizing agent under microwave radiation. The oxidation treatment on carbon nanotubes has a positive effect increasing the adsorbent–adsorbate interaction. Rate-control.ing mechanisms and equil.brium data are anal.zed using non-l.near model.. Non-l.near method is proposed as the most suitabl. method for determining the kinetic and equil.brium parameters. The val.es of adsorption energy(E) obtained from the Dubinin–Radushkevich isotherm,have been found around 0.371 and 0.870 k J·mol.1, indicating physical.adsorption. Therefore, the pseudo-second order model.represents better the kinetic experimental.data. The resul.s show that the l.ngmuir isotherm provides a sl.ghtl. better fit to the experimental.data compared with the Freundl.ch isotherm, indicating homogeneous distribution of active sites on carbon nanomaterial. and monol.yer adsorption. The separation factors Rl.re found in the range of 0–1, suggesting that the adsorption process is suitabl. for al. adsorbents. The mechanisms for hexaval.nt chromium removal.have been proposed as el.ctrostatic interactions and hydrogen bonding.
