ObjectiveTo determine the zinc levels in the expressed prostatic secretion (EPS) of the patients with different types of chronic nonbacterial prostatitis, and explore the reference value of zinc concentration in EPS in the diagnosis and treatment of prostatitis.
METHODSWe collected EPS samples from 35 healthy men and 173 patients with chronic nonbacterial prostatitis, including 65 cases of type ⅢA, 69 cases of type ⅢB, and 39 cases of type Ⅳ, according to the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI). We compared the zinc levels in the EPS samples among different groups and analyzed the correlations of zinc concentration with the NIH-CPSI scores, WBC count, pH value, and age of the subjects.
RESULTSThe participants were aged 17-65 (32.5±8.5) years. The zinc concentrations in the EPS were significantly lower in the ⅢA ([162.2±10.8] μg/ml) and ⅢB ([171.2±12.0] μg/ml) than in the Ⅳ ([234.6±17.9] μg/ml) (P<0.05 ) and the control group ([259.5±14.6] μg/ml) (P<0.05 ). The zinc level was correlated negatively with the NIH-CPSI pain score (r=-0.248, P<0.01), quality of life score (r=-0.232, P<0.01), severity score (r=-0.270, P<0.01), total NIH-CPSI score (r=-0.281, P<0.01), and the pH value in EPS (r=-0.208, P<0.01), but showed no correlation with the WBC count and age of the subjects.
CONCLUSIONSThe reduced zinc concentration in the EPS of the patients with chronic nonbacterial prostatitis may be associated with the pain symptoms of the disease, which suggests the potential reference value of measuring the zinc concentration in EPS in the diagnosis and treatment of prostatitis.

8.Research progress in novel PA protein members of influenza A viruses.
Chinese Journal of Virology 2014;30(6):689-693
Influenza poses a great threat to life and health in populations worldwide. Studies regarding the protein components of influenza viruses will facilitate the research and development of vaccines and diag nostic reagents. The influenza virus contains both structural and non-structural proteins. From the outset, it has been accepted that an influenza A virus possesses eight gene segments that encode eight corresponding viral proteins, respectively. Research has demonstrated that the M gene encodes the M2 ion channe! protein and the NS gene encodes the non-structural protein, NS2. In recent years, several novel viral proteins have been identified from influenza A viruses. This article will briefly describe the state of current research into PA-related proteins of influenza A viruses.

A total of 16 Taenia multiceps isolates collected from naturally infected sheep or goats in Gansu Province, China were characterized by sequences of mitochondrial cytochrome c oxidase subunit 1 (cox1) gene. The complete cox1 gene was amplified for individual T. multiceps isolates by PCR, ligated to pMD18T vector, and sequenced. Sequence analysis indicated that out of 16 T. multiceps isolates 10 unique cox1 gene sequences of 1,623 bp were obtained with sequence variation of 0.12-0.68%. The results showed that the cox1 gene sequences were highly conserved among the examined T. multiceps isolates. However, they were quite different from those of the other Taenia species. Phylogenetic analysis based on complete cox1 gene sequences revealed that T. multiceps isolates were composed of 3 genotypes and distinguished from the other Taenia species.

A GeXP based multiplex PCR assay was developed to simultaneously detect six different chicken respiratory viruses including H5, H7, H9 subtypes of avian influenza virus(AIV), new castle disease virus (NDV), infectious bronchitis virus(IBV) and infectious laryngotracheitis virus(ILTV). According to the conserved sequences of genes of each pathogen, seven pairs of specific primers were designed, and the reaction conditions were optimized. The specificity and accuracy of GeXP were examined using samples of single and mixed infections of virus. The sensitivity was evaluated by performing the assay on serial 10-fold dilutions of cloned plasmids. To further evaluate the reliability, thirty-four clinical samples were detected by GeXP. The corresponding specific fragments of genes were amplified. The detection limit of GeXP was 10(2) copies/microL when all of 7 pre-mixed plasmids containing target genes of six chicken respiratory viruses were present. In the detection of thirty-four clinical samples, the results of GeXP were accorded with the viral isolation completely. In conclusion, this GeXP assay is a rapid, specific, sensitive and high-throughput method for the detection of chicken respiratory virus infections. It can be applied in rapid differential diagnosis for clinical samples, and also provide an effective tool to prevent and control chicken respiratory diseases with similar clinical symptoms.
