Objective To understand the effect of circumcision in reducing high-risk human papilloma virus (HPV) infection in male adults. Methods One hundred and twenty-eight married adults with phimosis who underwent circumcision enrolled in the case group and high-risk HPV of urethral discharge specimens were detected before and 2 years after operation. A total of 128 cases of phimosis without circumcision were recruited in the control group. High-risk HPV infection rates were compared between the two groups. Results The highrisk HPV infection rates in the two groups were comparable at baseline. In the circumcision group, high-risk HPV infection rate was 27. 3% preoperative and it significantly decreased to 12.5% two years after operation( x2 =8. 839 ,P =0. 005). In the control group,high risk HPV infection rate was 28. 1% at baseline and it was 25.0%two years later, with no significant difference (x2 =0.320,P = 0.671).Conclusion Circumcision can significantly reduce high-risk HPV infection. Promoting circumcision actively in our country may have an important role in preventing high-risk HPV infection.

Objective To establish a duplex fluorescence PCR for detection of HIV proviral DNA and to evaluate its application for early diagnosis of HIV infection in infants .Methods A duplex fluores-cence PCR system was set up based on TaqMan technology for detection of human ribonuclease P ( RNase P) gene and long terminal repeat ( LTR) region of HIV.A recombinant plasmid containing the targeted gene fragment , pTG19-T, was constructed by TA cloning technique and used as the template for evaluation of sen -sitivity of the assay .Blood samples from 11 healthy individuals and 98 HIV-infected patients were collected and detected to validate the assay specificity .The assay of duplex fluorescence PCR was then carried out to detect 96 infant blood samples collected from several maternal and child health hospitals in Zhejiang province from January 2011 to September 2012 for early diagnosis of HIV infection .The results were compared with those by using the Roche HIV DNA qualitative detection kit .Results The established duplex fluorescence PCR could specifically detect HIV proviral DNA with a specificity of 100%and a detection sensitivity of 100 cps per reaction .The coincidence rate between the established assay and the Roche HIV DNA qualitative de -tection kit was 100%in the detection of 96 blood samples .Conclusion The duplex fluorescence PCR as-say showed advantages of cost-effectiveness , convenience , good specificity and accuracy with high sensitivi-ty.It could be used for early diagnosis of HIV infection in infants and also as a general technical platform for the detection of HIV proviral DNA .

Tolvaptan is a novel oral selective arginine vasopressin V2 receptor antagonist.Tolvaptan improves heart failure signs and symptoms without serious adverse events.Tolvaptan has no effect on all-cause mortality and cardiovascular death or admission rate for heart failure.But in heart failure patients with hyponatremia,tolvaptan can decrease cardiovascular death and admission rate for heart failure.

Objective To investigate the diagnostic and predictive value of measuring peritoneal inflammatory cytokines in predicting biliary fistulas in patients undergoing biliary surgery.Methods Peritoneal samples and serum samples of 3227 biliary surgery patients were collected on the first,third,fifth postoperative day,and IL-6,IL-8,IL-10,TNF-? and CRP of the samples were measured.Patients were divided into two groups:those with clinical evidence of biliary fistulas and those without any evidence of biliary fistulas.The age,sex,operative method and operative time between the two groups were compared.Results There was a negative correlation between biliary fistulas and age,sex and operation mode;but blood loss,operation time and common bile duct diameter had positive correlation with biliary fistulas.Peritoneal cytokine levels were significantly higher in patients with biliary fistulas as compared to those without biliary fistulas.Conclusions The peritoneal cytokine level is a sensitive parameter of peritoneal inflammation and can be as an additional diagnostic tool for the early prediction of biliary fistulas after biliary surgery.

Objective This study is to investigate cytokine pathway,Jak-Stat signal pathway,neuroactive ligand-receptor pathway gene expression pattern of peripheral blood mononuclear cell(PBMC) of primary sjgren syndrome patients.Methods The PBMC sample of 3 patients with sjgren syndrome and 3 healthy volunteers with consistent age were collected.The total RNAs was extracted from the PBMC samples,and reverse transcripted in vitro transcription(IVT),labeled with Cy5/Cy3 and hybridized on the gene chips.After scanning and data extraction with LuxScan 3.0,differentially expressed genes were analyzed with SAM method.The online tool of molecule analysis system(MAS) was used for biological knowledge mining.Results Statistical difference was calculated between the patient and control group in the following three pathways: cytokine pathway,Jak-Stat signal pathway,neuroactive ligand-receptor pathway.Among these,genes of IL-2RA,IL-10 were up-regulated and genes of PF4,GZMA were down-regulated.Conclusion Understanding of differently expressed genes should help us disclose the potential molecular mechanism underlying the development process of pathogenesis of primary Sjgren′s syndrome.And the research may provide new target therapy for SS.

OBJECTIVE To investigate the bacterial resistance of clinical isolates from pediatric hospital for the guidance of rational use of antibiotics.METHODS Disc diffusion test(Kirby-Bauer method) was used to study the antimicrobial resistance(fastidious bacteria were detected by E test).WHONET5 was applied for analysis.(RESULTS) In the period of study from 2002 to 2003,2 303 strains which were the first isolated from each patient were collected.Of 2 303 clinical isolates,Gram positive organisms accounted for 29.7%,Gram negative ones for 70.3%.Escherichia coli,Klebsiella spp,Staphylococcus aureus,coagulase-negative staphylococci and Pseudomonas aeruginosa were the most common strains among the isolates.Meticillin-resistant S.aureus(MRSA) and meticillin-resistant coagulase(-negative) staphylococci(MRCNS) accounted for 9.7% and 67.6% of S.aureus and coagulase-negative(staphylococci),respectively.Resistant rates of MRSA and MRCNS were higher than that of meticillin-susceptible S.aureus(MSSA) and meticillin-susceptible coagulase-negative staphylococci(MSCNS) to antimicrobial agents commonly used in clinic.No vancomycin resistant strains of staphylococci were found. 4.1% of Enterococcus spp were vancomycin resistant strains.Resistant rate of Streptococcus pneumoniae was 11.9% to penicillin. Most of isolates of Enterobacteriaceae were susceptible to imipenem.The incidences of E.coli and Klebsiella spp producing extended spectrum beta-lactamases(ESBLs) isolates were 49.7% and 63.1%,respectively.The resistance rates of(ESBLs) producing strains to antimicrobial agents(except carbapenems) were higher than those of ESBLs nonproducing ones.CONCLUSIONS Bacterial resistance is still or even a more serious clinical problem than before.The(surveillance) of antimicrobial susceptibility in pediatric hospital is of great significance.It is also very important to promote the rational use of antimicrobial agents so that resistance is minimized and take effective strategy for the control of the problem.

Objective To investigate the disinfectant-resistant gene qacA in Staphylococcus aureus isolates from the First Affiliated Hhospital of Chongqing Medical University. Methods A total of 126 S. aureus strains were isolated. The minimum inhibitory concentrations (MICs) of 4 representative monovalent and bivalent disinfectants were determined. Polymerase chain reaction (PCR) was employed to analyze the prevalence of qacA gene in these strains. Disk diffusion method was used to identify methicillin-resistant S. aureus (MRSA).Results Of the 126 S. aureus strains, 12 were positive for qacA gene. The prevalence of qacA in these strains was 9.5%. The prevalence of qacA gene in MRSA was 17.3%. Conclusions qacA gene is prevalent in the clinical isolates of S. aureus.
