Objective To investigate the situation of human papillomavirus (HPV) infection and the distribution of HPV genotypes among women attending hospital in Meizhou,Guangdong province.Methods Flow-through hybridization and gene chip technique was used to detect HPV in cervical exfoliated cell specimens collected from 24 450 women for HPV screening in Department of Gynecology,Meizhou People's Hospital,Meizhou Hospital Affiliated to Sun Yat-sen University,and then the situation of HPV infection and distribution of HPV genotypes were analyzed.Results Among 24 450 female exfoliated cell specimens,3 922 were found to be positive for HPV infection,with the total infection rate of 16.04％.Among 3 922 samples,the top three high-risk subtypes of HPV were HPV-16 (30.37％),HPV-52 (17.77％) and HPV-58 (15.53％),the majority of low-risk HPV was HPV-CP8304 (5.61％).The positivity of various HPV types peaked among 30-50 years old.The differences of the HPV positive rates in different age groups was statistical significance (P ＜ 0.001).Conclusions The majority of women attending hospital detected with HPV-16 in Meizhou and the positivity of various HPV types peaked among women aged 30-50 years.Genotyping of HPV was meaningful for preventing and treating cervical cancer.

To develop a specific, rapid, and convenient immunochromatography assay (ICA) to detect the rabies antibody in clinical sample from immuned dogs by rabies vaccine. Colloidal gold particles labeled with purified rabies virus (CVS11) were used as the detector reagent. The staphylococcal protein A (SPA) and pured rabbit anti-rabies virus IgG were blotted on the test and control regions of nitrocellulose membrane. Then the strip was assembled with sample pad, absorbing pad, and dorsal shield. The assay samples (261 dog's serum) were collected from Wildlife Rabies Disease Diagnostic Laboratories of Ministry of Agriculture in China, Institute of Military Veterinary, Academy of Military Medical Sciences and other six provinces, including rabies virus positive and negative serum. The performance of the strip was compared to fluorescent antibody virus neutralization test. The neutralizing antibody titer could be detected above 0.5 IU. The strip did not change of performance when stored at room temperature for 12 months. It may offer reference of neutralizing antibody titer level after dogs immuned rabies vaccine and determin whether the dogs need to be immuned again.
