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 .

This paper summarizes the features of web sites that would be useful to infectious diseases physicians by exploring the Internet through search engine including Google,Baidu and Yahoo.Meanwhile,suggestions from professional forums,web sites and publications are also taken into consideration.Nine Comprehensive sites containing three categories and more of microbial pathogens,nine special sites for parasites,four special sites for fungi,two special sites for viruses and two special sites for bacteria are collected.Subjective navigation for each site is given.Features of these sites,including laboratory images,clinical images and number of images are also described.

To use Agrobacterium rhizogenes-induced hairy roots to create new germplasm of Dianthus caryophyllus, we transformed D. caryophyllus with A. rhizogenes by leaf disc for plant regeneration from hairy roots. The white hairy roots could be induced from the basal surface of leaf explants of D. caryophyllus 12 days after inoculation with A. rhizogenes ATCC15834. The percentage of the rooting leaf explants was about 90% 21 days after inoculation. The hairy roots could grow rapidly and autonomously in liquid or solid phytohormone-free MS medium. The transformation was confirmed by PCR amplification of rol gene of Ri plasmid and silica gel thin-layer chromatography of opines from D. caryophyllus hairy roots. Hairy roots could form light green callus after cultured on MS+6-BA 1.0-3.0 mg/L + NAA 0.1-0.2 mg/L for 15 days. The optimum medium for adventitious shoots formation was MS + 6-BA 2.0 mg/L + NAA 0.02 mg/L, where the rate of adventitious shoot induction was 100% after cultured for 6 weeks. The mean number of adventitious shoot per callus was 30-40. The adventitious shoots can form roots when cultured on phytohormone-free 1/2 MS or 1/2 MS +0.5 mg/L NAA for 10 days. When the rooted plantlets transplanted in the substrate mixed with perlite sand and peat (volume ratio of 1:2), the survival rate was above 95%.

The buccoversion malpositon of maxillary second molars is one kind of common malocclusion.It can lead to damages to stoma-tognathic system.The adjustable maxillary molar retractor is an effective tool in the early treatment of this kind of malposition.

Objective To explore a method with good repeatibility, less interference factors and easily controllable experimental conditions for evaluating the filtering efficiency of air filters Methods This evaluating method referred to Standard Examination Method of Household Portable Electrically Powered Air Purifying Set of America(ANSI/AHAM Ac 1 1998) and used the index of the frequency of air filtration (TAF) in the determination.The required sampling space volumes and the sampling duration of testing were determined based on the related different of air capacities.The levels of CO,CO 2,inhalable particulate(IP),NO 2,SO 2 and total count of air bacteria in filtered air were determined Results IP and total count of air bacteria could be used as sensitive indexes for evaluating the efficiency of air filtration Conclusion This method avoided many interference factors.It presented shorter duration of examination,good repeatibility and stability,easy operation and acturally reflected the efficiency of air filters

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.

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.
