The relationship between serum uric acid(SUA) and hypertension was investigated and the interactions of SUA with metabolic risk factors was assessed. Blood pressure and biomarkers features were evaluated for all the8 415 individuals from a community-based health examination survey in Xuzhou, and the statistical analysis was made. Raised blood pressure was associated with increased SUA concentration(P＜0.01). Age and high density lipoprotein cholesterol(HDL-C) significantly interacted with SUA(P for interaction=0.012 and 0.001, respectively). There is significant association between SUA and hypertension, which may be affected by age and HDL-C levels.

BACKGROUNDThere is no agreement as to whether intensive glucose control in type 2 diabetes can reduce the incidence of macrovascular events in these patients. We performed a meta-analysis comparing intensive glucose control or conventional glucose control in randomized controlled trials.

METHODSDatabases including MEDLINE, EMBASE, and Cochrane controlled trials register, the Cochrane Library, and Science Citation Index were searched to find relevant trials. Outcome measures were the incidence of major macrovascular events.

RESULTSSix trials involving 28 065 patients were included. Analysis suggested that there was an obviously decreased incidence of major macrovascular events in patients having intensive glucose treatment vs. controls (RR 0.92; 95%CI 0.87, 0.98; P = 0.005). However, intensive glycemia control strategies in type 2 diabetes showed no significant impact on the incidence of death from any cause compared with conventional glycemia control strategies, intensive 14.7%, controls 12.0% (RR 0.95; 95%CI 0.80, 1.12; P = 0.55), as well as on the incidence of cardiovascular death, intensive 3.7%, controls 3.6% (RR 1.10, 95%CI 0.79, 1.53; P = 0.57).

CONCLUSIONSControl of glycemia to normal (or near normal levels) in type 2 diabetes appears to be effective in reducing the incidence of major macrovascular events, but there were no significant differences of either the mortality from any cause or from cardiovascular death between the two glycemia-control strategies.

OBJECTIVETo investigate the epidemiological features of the pathogens responsible for prostatitis in the Changshu area, and offer some evidence for the clinical treatment of prostatitis.

METHODSThis study included 2 306 cases of prostatitis that were all clinically confirmed and subjected to pathogenic examinations in 3 hospitals of Changshu area from 2008 to 2012. Neisseria gonorrhoeae, mycoplasma urealyticum and chlamydia trachomatis were detected by nucleic acid amplification ABI 7500, the bacterial data analyzed by VITEK-2 Compact, the drug-resistance to antibacterial agents determined using the WHONET 5.6 software, and the enumeration data processed by chi-square test and curvilinear regression analysis using SPSS 19.0.

RESULTSThe main pathogens responsible for prostatitis were found to be Staphylococcus haemolyticus (30%), Staphylococcus epidermidis (12%), Enterococcus faecalis (9%), Escherichia coli (6%), Staphylococcus warneri and Staphylococcus aureus (3%), Mycoplasma urealyticum (8%), chlamydia trachomatis (5%) and Neisseria gonorrhoeae (6%). Statistically significant increases were observed in the detection rates of Escherichia coli (chi2 = 17.56, P<0.05), Mycoplasma urealyticum (chi2 = 8.73, P<0.05), Chlamydia trachomatis (chi2 = 8.73, P<0.05) and Enterococcus (chi2 = 8.22, P<0.05), but not in other pathogens. The resistance rates of Gram-positive bacteria to erythromycin and benzylpenicillin G were both above 45%, but with no significant difference between the two, those of Oxacillin (chi2 = 10.06, P<0.05) and Cefoxitin (chi2 = 9.89, P<0.05) were markedly increased, but those of quinolones, gentamycin and clindamycin remained low, except rifampicin (chi2 = 11.09, P<0.05). The resistance rates of Gram-negative bacteria to cefazolin and ampicillin were relatively high (mean 57.3%), and those to ceftriaxone (chi2 = 11.26, P<0.05) and trimethoprim sulfamethoxazole (chi2 =11.00, P< 0.05) significantly high; those to amikacin, cefepime, piperacillin/tazobactam and imipenem remained at low levels with no significant changes. However, the resistance rates of mycoplasma urealyticum to ciprofloxacin (chi2 = 11.18, P<0.05) and azithromycin (chi2 = 9.89, P<0.05) were remarkably increased.

CONCLUSIONGram-positive bacteria are the major pathogens responsible for prostatitis, but Escherichia coli, enterococcus and sexually transmitted disease pathogens are found to be involved in recent years. Quinolones and aminoglycosides are generally accepted as the main agents for the treatment of Gram-positive bacterial infection. However, rational medication for prostatitis should be based on the results of pathogen isolation and drug sensitivity tests in a specific area.

Objective To investigate the impact of transvaginal natural orifice transluminal endo-scopic surgery(NOTES)-assisted laparoscopic nephrectomy on female sexual function and quality of life . Methods This was a prospective study on the change of female sexual function and quality of life of female patients who underwent transvaginal NOTES-assisted laparoscopic nephrectomy from May .2011 to Nov. 2012.A total of 42 cases were included in this study (28 of them with severe hydronephrosis , non-functio-ning kidney , 11 with pyelonephrosis , 1 with renal tuberculosis , 1 with duplex kidney complicated with hy-dronephrosis, and 1 with renal angiomyolipoma ).The mean age was 36.9±5.3 (26-45) years, and the mean body mass index was 21.7±2.6 (14.7 to 27.1) kg/m2.Twenty-four cases were operated on the left side, 18 cases on the right .The female sexual function and quality of life were assessed before and 4 months, 7 months and 1 year after surgery using the Female Sexual Function Index (FSFI) questionnaire and the MOS 36-item Short-Form Health Survey (SF-36), respectively. Results The mean FSFI of 42 cases preoperatively and 4 months, 7 months and 1 yr postoperatively were 27.74 ±4.34, 27.19 ±4.49, 28.54±4.23, and 28.68 ±4.19, respectively.There was no statistically significant difference among them (F=1.111, P=0.346).Compared with that of preoperation , the physical function, vitality, metal health, body pain, and general health of the patients were improved , but the role-physical, role-emotion and social function were not improved at postoperative month 4 and month 7 (P<0.05).Each item of SF-36 was im-proved after postoperative 1 year ( P<0.05) . Conclusions Transvaginal NOTES-assisted laparoscopic ne-phrectomy does not cause negative effect on the female sexual function .The quality of life can be improved after operation .The physical function is improved at early stage , and the psychological function as well .

OBJECTIVETo define the differences in gene expression patterns between glycidyl methacrylate (GMA)-transformed human lung fibroblast cells (2BS cells) and controls.

METHODSThe mRNA differential display polymerase chain reaction (DD-PCR) technique was used. cDNAs were synthesized by reverse transcription and amplified by PCR using 30 primer combinations. After being screened by dot blot analysis, differentially expressed cDNAs were cloned, sequenced and confirmed by Northern blot analysis.

RESULTSEighteen differentially expressed cDNAs were cloned and sequenced, of which 17 were highly homologous to known genes (homology = 89%-100%) and one was an unknown gene. Northern blot analysis confirmed that eight genes encoding human zinc finger protein 217 (ZNF217), mixed-lineage kinase 3 (MLK-3), ribosomal protein (RP) L15, RPL41, RPS 16, TBX3, stanniocalcin 2 (STC2) and mouse ubiquitin conjugating enzyme (UBC), respectively, were up-regulated, and three genes including human transforming growth factor beta inducible gene (Betaig-h3), alpha-1,2-mannosidase 1A2 (MAN 1A2) gene and an unknown gene were down-regulated in the GMA-transformed cells.

CONCLUSIONAnalysis of the potential function of these genes suggest that they may be possibly linked to a variety of cellular processes such as transcription, signal transduction, protein synthesis and growth, and that their differential expression could contribute to the GMA-induced neoplastic transformation.
