Objective To compare the health related quality of life (HRQoL) of ileal conduit versus orthotopic ileal neobladder using the FACT-BL scale.Methods One hundred and thirty patients underwent radical cystectomy and urinary diversion for invasive bladder cancer from Jan 2006 to Dec 2010 at our hospital.According to different urinary diversions,patients were divided into ileal conduit (IC) and orthotopic ileal neobladder (NB).HRQoL was assessed using FACT-BL.The following scores calculated from the FACT-BL questionnaire and list:physical well-being ( PWB ),social/family well-being ( SWB ),emotional well-being(EWB),functional well-being( FWB),overall bladder-special subscale and total FACT-BL were included.A high FACT score indicated a high level of HRQoL.The medical records of each patient were then reviewed.Clinical parameters including age,sex,type of diversion and pathological status were recorded and analyzed.Results A total of 94 questionnaires were collected,of these patients 50 had an IC and 44 had an NB.Among the respondents,the age at surgery was significantly younger in NB group than IC group (P =0.014 ).While the percent of males,follow-up years and pathological stage T3 or greater revealed no significant difference.The NB group got significantly higher scores in PWB,SWB,EWB and FACT-BL than the IC group.Which indicated that the HRQoL was higher in patients following orthotopic ileal neobladder.Conclusions The HRQoL was better in patients who followed orthotopic ileal neobladder than those who followed ileal conduit.This may indicate that orthotopic ileal neobladder should be considered first when making a decision about which urinary diversion should be used.

Objective To compare the accuracy of real-time myocardial contrast echocardiography (RT-MCE) with DISA-SPECT in detecting hibernating myocardium. Methods Fourteen hospitalized patients with regional wall motion abnormalities (RWMA) underwent RT-MCE, DISA-SPECT, coronary angiography and percutaneous coronary intervention(PCI). Every left ventricular myocardial segment image was acquired and evaluated according 16-segment model of American Society of Echocardiography. The Motion of every segment was observed by echocardiography after 1,3,6 months. The gold standard is that the motion of ventricular segment get better after PCI. The images of RT-MCE and DISA-SPECT were analyzed semi-quantitatively. Results The sensitivity,specificity,accuracy of RT-MCE and DISA-SPECT in detecting hibernating myocardium were 74.60%, 91.7%, 81.3% and 93.3%, 75.0%, 86.2%, respectively. RT-MCE had more value in specificity while DISA-SPECT had more value in sensitivity. The correlation between two methods was good in detecting hibernating myocardium. Conclusions RT-MCE and DISA-SPECT can be used as valuable methods to detect hibernating myocardium, the correlation between two methods is good and they have more value in specificity and sensitivity respectively.

During hepatitis B virus(HBV)infection,the host immune response,including the presence of functional HBV-specific T cells and HBV-specific antibody-producing B cells,ultimately determines the HBV infection outcome:either the virus is cleared,or infection persists.Functional exhaustion of HBV-specific CD8+cytotoxic T cells is the most important immune feature in chronic HBV infection.However,chronic HBV infection also re-writes humoral immunity,whereby B cells are the leading participants.In this review,we highlight HBV-specific B cell responses and propose future directions for research aimed at the generation of more efficient immunotherapeutic strategies.

OBJECTIVETo study the molecular characteristics and antibiotic resistances of Vibrio cholerae (V. cholerae) O1 isolates in Hangzhou in 2009.

METHODSThe virulence genes ctxA and tcpA of the thirty V. cholerae O1 isolates from 7 counties and districts of Hangzhou were detected by PCR. Pulsed-field gel electrophoresis (PFGE) was performed for molecular typing and similarity analysis. Antibiotic resistances of these isolates were measured by the Kirby-Bauer method.

RESULTSVirulence gene analysis showed that 80.00% (24/30) of the genotype in V. cholerae isolates was ctxA- and tcpA+, 13.33% (4/30) was ctxA- and tcpA-, and 6.67% (2/30) was ctxA+ and tcpA+. Twenty-seven isolates tested were typed into 11 PFGE patterns (P1-P11). Twenty-three isolates with genotype ctxA- and tcpA+ were clustered into 7 PFGE patterns (P1-P7, termed P1-like cluster) with the similarity to be equal or greater than 91.4%, and 56.52%(13/23) of them belong to P1. 7 isolates with very high similarity (97.6%), belonging to P1 (6 isolates), and P2 (1 isolate), respectively, were collected from one foodborne disease outbreak. The resistant rates of the 24 isolates with genotype ctxA- and tcpA+ to ampicillin, tobramycin and amikacin were 20.83% (5/24), 4.17% (1/24) and 4.17% (1/24), respectively.

CONCLUSIONThe genotype of the epidemic strains of V. cholerae O1 isolates in Hangzhou in 2009 with high similarity was ctxA- and tcpA+; The level of drug resistances of this kind of V. cholerae O1 isolates were not high.

AIMTo establish a simple, rapid and accurate electroanalytical method for water soluble porphyrin meso-tetrakis-(4-sulfonatophenyl) porphyrin (TPPS4); to clarify the reaction between water soluble porphyrins and bovine serum albumin (BSA); and to determine the interaction of TPPS4 with BSA in the absence of presence of cyclodextrins (CDs), separately.

METHODSThree methods including LSV, UV spectroscopy and fluorescence spectroscopy had been employed to the relevant experiments. The way of employing three methods at the same time could make the experiment results more reliable.

RESULTSIn the supporting electrolyte of NaH2 PO4-Na2 HPO4 (pH 7.18), a sensitive reduction peak of TPPS4 was found by linear sweep voltammetry (LSV), the peak potential (Ep) was -0.70 V (vs SCE). The relationship between the second derivative peak of LSV (ip") and the concentration of TPPS4 was linear from 1.0 x 10(-7) mol x L(-1) to 1.0 x 10(-5) mol x L(-1), the square of correlation coefficients (r2) were 0.998 3 and 0.999 3, respectively. The relative standard deviation (RSD) was 0.56% (n = 5). The mean recovery of TPPS4 was 99.59%. In NH4Cl-NH3 x H2O buffers (pH 9.05), it was proved that BSA and TPPS4 could interact with each other and form 1 : 1 TPPS4-BSA supramolecular system. Moreover, the interaction between TPPS4 and BSA had been investigated by adding cyclodextrins (CDs). The interaction of TPPS4 with BSA was facilitated both by hydroxypropyl-beta-CD (HP-beta-CD) and sulforbutylether-beta-CD (SBE-beta-CD).

CONCLUSIONAn electroanalytical method for TPPS4 has been established by LSV. The porphyrin drugs included by CDs could react with protein existing inside the human body easier. The consequences of this article also show that CDs will play important role in controlling and releasing the porphyrin drugs.

OBJECTIVETo study the protective effects of polysaccharides from Dendrobium huoshanense (DHP) against CCl4-induced liver injury in mice.

METHODEighty male Kunming mice were randomly divided into normal control group, model control group, dextran control group, starch control group, hydrolyzate control group, three different dose of DPH groups consisting of high-dosage group, middle-dosage group and low-dosage group (200, 100, 50 mg x kg(-1)). Each group contained ten mice. The mice were treated with DHP via intragastric administration for 15 days before treatment of 50% CCl4 in olive oil for consecutive two days. Both alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities in serum and superoxide dismutase (SOD) activities and malondialdehyde (MDA) contents in liver tissues were determined in all groups. Immunohistochemistry was used to detect the expression of TNF-alpha in hepatic tissue. Hepatic histopathological examination was observed.

RESULTDHP effectively decreased the activities of ALT and AST in serum and the contents of hepatic MDA, and restored hepatic SOD activities in acute liver injury mice. Liver tissue damage induced by CCl4 was ameliorated in mice with DHP administration through histopathology examination. Furthermore, the expression of TNF-alpha was greatly decreased in groups treated with polysaccharides.

CONCLUSIONDHP has a significantly hepatoprotective effect on CCl4-induced acute liver injury in mice. Protective effect of DHP on the liver may be related to its function of scavenging free radicals and inhibiting lipid peroxidation and TNF-alpha expression.
