OBJECTIVETo evaluate the application of shear wave elastography (SWE) combined with transition zone biopsy in the detection of prostate cancer (PCa).
METHODSA total of 489 patients with suspected PCa underwent transrectal ultrasonography (TRUS) and SWE-guided prostatic biopsy. We evaluated the role of SWE combined with transition zone biopsy in promoting the detection rate in comparison with the results of biopsy pathology.
RESULTSThe pathological results confirmed 221 malignant and 268 benign cases. Based on systematic biopsy, SWE combined with transition zone biopsy achieved a detection rate of 45. 19% , significantly higher than that of systematic biopsy alone (33.13%) (P < 0.05). The diagnostic sensitivity, specificity, and accuracy of SWE were significantly better than those of TRUS (P < 0.05). The mean elasticity (Emean) of SWE was remarkably higher for malignant than for benign lesions ([40.1 ± 9.5] vs [21.6 ± 8.3] kPa, P < 0.05). With 28.5 kPa as the threshold of the Emean value, the area under the ROC curve was 0. 899, and the diagnostic sensitivity and specificity were 88.71% and 86.23%, respectively.
CONCLUSIONSWE combined with transition zone biopsy could significantly improve the detection rate of prostate cancer.

AlM: To investigate the effect of endocapsular phacoemulsification cataract extraction and intraocular lens (lOL) implantation with a 1. 8mm or 3. 0mm clear corneal incision on total root mean square ( RMS ) value of the cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film.
METHODS:ln a prospective study, 156 age- related patients ( 196 eyes ) were randomly distributed into two groups. 1. 8mm-group comprised 94 eyes that had a silicone lOL inserted through a 1. 8mm sutureless clear corneal incision, while, 3. 0mm- group comprised 102 eyes through a 3. 0mm clear corneal incision. Postoperatively, the changes in the total RMS value of the cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film at 1wk, 1 and 3mo were determined respectively.
RESULTS:ln both groups, postoperatively at 1wk,there were statistically significant differences ( P<0. 05 ) in the total RMS value of the cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film, while, there were statistically minimal differences ( P< 0. 05 ) between 1. 8mm-group and 3. 0mm-group at 1mo, but were not statistically significantly different ( P > 0. 05 ) between two groups at 3mo postoperative.
CONCLUSlON:This study confirms that incision size has strong impact on the corneal higher-order aberrations, especially, 3. 0mm incision caused significant differences in the total RMS value of cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film compared with 1. 8mm micro-incision, therefore, micro-incision is very beneficial for clinical use in phacoemulsification.

Pseudomonas sp. M18, one of plant-growth-promoting rhizobacteria, can produce secondary metabolites including phenazine-1-carboxylic acid (PCA) and pyoluteorin (Plt). PA2572 gene coding protein is a probable two-component response regulator in Pseudomonas according to homologous speculations. In order to investigate its genetic function, PA2572 homologous gene, ppbR, was amplified from M18 genome, inactivated by inserting a Gm cassette. The resulting reconstruct was introduced into the M18 genome using homologous recombination technique, so as to obtain the null mutant M18P. The results showed that the M18P has less flagellar swimming and swarming motility, and yielded fewer PCA. The production of PCA was only 50% of the wild type. However, there was no remarkable difference between mutant and wild type in producing pyoluteorin in KMB medium.

From 2006 to 2008, the susceptibility of different species of animal hosts to Campyebacter jejubni infection was observed in various areas of Jiangsu province, in which the API Campy System was used to perform the biochemical identification and the multiple PCR assay was employed to analyse the C.jejuni isolates from 3010 specimens of fouls. Cattle, pigs and monkeys, and in addition, the susceptibility of isolates to various antibiotics was also determined. In these specimens investigated 402 samples were found to be positive in the detection of C.jejuni with a positive detection rate of 13.36%. The positive detection rates in chicken, water fouls, milk cows, pigs, monkey, red crowned crane and wapiti were 15.83% (258/1630), 10.4% (52/100), 8.24% (42/510), 15.63% (25/160), 15% (15/100), 12.5% (15/80) and 0% (0/30) respectively. Meanwhile, the antibiotics to which the isolates from different hosts showed high rate of sensitivity to 27 antibiotics of 10 varieties included: chloromycetin (100%), Almocylin (99.7%), amicarcin (92.59%), cefprozil (91.67%), alchimycin (90.74%); while the antibiotics to which these isolates showed high rate of resistance were compound neoromin (99.7%), cefoperazone (99.07%), trimethoprim (97.22%), cepronatin (91.67%), cepromondo (99,07%) respectively. It is evident that the susceptibility of different hosts to C.jejuni infection and the status of drug-resistance of the isolates appear to be quite different and more complicated in Jiangsu province.
