Purpose Chronic nephropathy model was established with New Zealand rabbit, and the development of chronic nephropathy was monitored using virtual touch tissue quantification (VTQ) technique, to provide the experimental basis for chronic renal fibrosis assessment using VTQ technique. Materials and Methods Thirty-eight healthy New Zealand white rabbits were selected, of which 32 were induced into chronic nephropathy model with daily intravenous ear vein injection of cationic bovine serum albumin (C-BSA), with the other 6 rabbits without C-BSA injection as control group. At the end of 0, 2, 4, 6, 8 weeks, VTQ was used to measure the hardness of renal cortex in rabbits, then the rabbits were slaughtered to assess the pathological changes in kidney, correlation analysis between the VTQ parameters and the pathological parameters was performed. Results VTQ value of rabbit kidney cortex at 0 week, 2 weeks, 4 weeks, 6 weeks and 8 weeks was (1.68±0.25) m/s, (1.70±0.31) m/s, (1.87±0.35) m/s, (2.19±0.31) m/s and (2.46±0.46) m/s respectively, difference of VTQ values between 6 weeks and 4 weeks was statistically signiifcant (P<0.05), and also signiifcant when compared 8 weeks with 4 weeks and 6 weeks (P<0.05). Glomerulosclerosis index of 4 weeks, 6 weeks, 8 weeks were 0.81±0.40, 1.43±0.46 and 2.15±0.46 respectively, and tubular interstitial collagen deposition score were (14.29±4.62)%, (26.28±11.06)%, (42.37±10.09)%, which were all significantly higher than that in 0 week and 2 weeks, fibrosis increased gradually with the course, the difference was statistically signiifcant (P<0.05). Correlation analysis showed that the VTQ value of renal cortex was positively correlated with glomerulosclerosis index (r=0.663, P<0.05) and tubular interstitial collagen deposition score (r=0.652, P<0.05). Conclusion VTQ technique is able to detect the VTQ change of renal cortex as the disease progressed in rabbits with chronic renal nephropathy, which was in a positive association with fibrosis index, suggesting that virtual touch tissues quantitative technology can be an important method to evaluate renal ifbrosis in chronic renal nephropathy.

Objective To establish a new methA of detecting vWF function. Methas The capability of vWF to bind collagen was evaluated with ELISA. Results The assay′s sensitivity was 0.001 U/ml. Coefficient of variation for inner-batch and inter-batch were 3.34 and 6.70 respectively.The vWF:CBA value of plasma was(90.24?22.87)% in 20 normal subjects. The vWF:CBA value was (31.94?27.36)% in 54 vWD, (35.22?20.02)% in 10 type 1 vWD, (8.74?6.38)% in 10 type 2A vWD and (0.70?0.58)% in 6 type 3 vWD,the values of all four vWD groups were lower than that of normal group( P

ObjectiveTo explore the correlation of contrast-enhanced ultrasound (CEUS) parameters and the pathologic parameter of renal fibrosis.MethodsThirty-eight healthy New Zealand rabbits were randomly divided into the blank control group and the experimental group. The rabbits model was built by intravenous injection of C-bovine serum albumin (C-BSA) to rabbits of the experimental group. According to the different time points (2, 4, 6 and 8 weeks) after the injection of C-BSA, the rabbits in experimental group were randomly divided into 4 sub groups, 8 in each group. We collected the data of the CEUS parameters in the control group and the experimental group. Moreover, the renal tissues of the rabbits underwent pathologic examinations. Then, correlation analysis of CEUS parameters with parameters of renal fibrosis was performed.ResultsDynamic changes of CEUS parameters: Renal cortical perfusion reduced from 6 weeks after the injection, manifested as the time to peak (TTP) and mean transit time (MTT) of the experimental group were longer than those of control group and the derived peak intensity (DPI) of the experimental group was lower than that of control group (P<0.05 respectively). The DPI and TTP at 8 weeks after the injection of the experimental group was significantly lower than those of the control group [(26.96±2.34) dbvs (35.04±1.62) db,P<0.05; (24.31±1.82) svs (18.64±1.15) s,P<0.01]. Changes of each renal fibrosis parameter: we found that the results of the glomerulosclerosis indexes of the experimental group (4 weeks, 6 weeks and 8 weeks after the injection) were significantly higher than those of the control group (0.81±0.36, 1.43±0.25 and 2.15±0.30vs 0.13±0.07, allP<0.01). The tubular interstitial collagen deposition scores of the experimental group (4 weeks, 6 weeks and 8 weeks after the injection) were significantly higher than those of the control group (14.29%±4.62%, 26.28%±10.09% and 42.37%±10.41%vs 1.21%±0.15%, allP<0.01). As the disease progressed, the results of each parameter increased. Pearson correlation analysis showed that the TTP of renal cortex was positively correlated with the glomerulosclerosis index and tubular interstitial collagen deposition score (r=0.866 and 0.785, bothP<0.01). The DPI of renal cortex was negatively correlated with the glomerulosclerosis index and tubular interstitial collagen deposition score (r=-0.724 and -0.739, bothP<0.01).ConclusionsThe results showed that CEUS could evaluate microcirculation perfusion of renal cortex. There is a positive association between TTP and fibrosis index. There is a negative association between DPI and fibrosis index. Thus, CEUS is an important method to evaluate the renal fibrosis in chronic renal nephropathy.

Objective To investigate the antimicrobial resistance mechanisms and genetic homogeny of Salmonella from community acquired infections in Shenzhen,China.Methods Ninety-three of Salmonella were isolated from 2002 to 2007 at Shenzhen People's Hospital,China.PCR and DNA sequencing were used to investigate the mutation in QRDR of the gyrA,gyrB,parC and parE.Plasmid mediated quinolone resistance genes including qnr and aac(6')-Ib-cr,β-lactamase genes including blaTEM,blaSHV,blaOXA, blaCTX-M, and class 1 integron were detected. All isolates were typed by PFGE. Results S. enterica typhi and S. enterica paratyphi A were susceptible to ampicillin, chloramphenicol, trimethoprim/sulfamethoxazole, ceftriaxone and ciprofloxacin, with the susceptible rate of 96%-100%. Fifty-two percent (13/25) of S. enterica typhi and 95% (61/64) of S. enterica paratyphi A were resistant to nalidixic acid. Twenty-four percent (6/25) of nalidixic acid-resistant S. enterica typhi and 94% (60/64) of nalidixic acid-resistant S. enterica paratyphi A showed decreased susceptibility to ciprofloxacin (MIC of 0. 125-1 μg/ml).All nalidixic acid-resistant (susceptible to ciprofloxacin ) Salmonella (NARS) isolates had a single substitution in the QRDR of GyrA, and 91% (68/75) of these isolates carried the substitution Ser83Phe in GyrA. Two mutations in the QRDR of GyrA were detected in both of two ciprnfloxacin-resistant Salmonella,with the additional one mutation in the QRDR of parC. Plasmid mediated quinolone resistance genes including qnr and aac(6')-lb-cr were not detected in any isolate. The blaCTX-M-14 gene was detected in a ceftriaxoneresistant isolate of S. enterica paratyphi A, with ISEcpl located on the upstream of it. Three muhidrugresistant strains of Salmonella all carried one 1 900 bp classⅠ integron gene cassette dhfrⅫ-orfF-aadA2,with the additional one β-lactamase gene of blaTEM-1, or blaOXA-30. Twenty-two distinct PFGE patterns were observed among twenty-five S. enterica typhi. The PFGE patterns of sixty-four S. enterica paratyphi A showed limited genetic diversity (average similarity of 91% ). Ninety investigated inpatients were infected in the community. Six patients infected by S. enterica paratyphi A had a travel history before infection. Conclusions Nalidixic acid-resistant S. enterica typhi and S. enterica paratyphi A are highly prevalent in Shenzhen,China. The mutation in the QRDR of GyrA is the prevalent mechanism responsible for the resistance to nalidixic acid in Slmonella. The great genetic similarity among S. enterica paratyphi A isolates indicates endemic disease from the presence of a single clone over 6-year period.
