Background Human papillomavirus (HPV) infection is the leading cause of genital diseases. It can cause a series of cervical lesions. The distribution of HPV genotypes indicates that the increased prevalence of high-risk HPV (HR-HPV) is positively correlated with the severity of cervical lesions. In addition, persistent HR-HPV infection is associated with the risk of cervical cancer. Considering the latest approval of homemade HPV vaccine in China and the prevalence of HPV distribution, this is of great significance for guiding HPV vaccination work. Objective Our study’s purpose was to examine trends of cervical HPV infection rate in each 5-year age group from 2011 to 2019. Methods Retrospective analysis of human papillomavirus prevalence rate of 59,541 women from 2011 to 2019 in the District Zhoupu of Shanghai City in China. HPV genotype testing is performed using a commercial kit designed to detect 15 high-risk HPV genotypes and 6 low-risk HPV genotypes. Trends were examined for each 5-year age group. Results In the District Zhoupu of Shanghai City in China, the prevalence rate of cervical HPV increased significantly among women aged 15–34 years. The most prevalent HR-HPV genotypes were 52, 16, 58, 53, 39, and 51. Conclusion Cervical HPV prevalence rate is very high in younger women in suburb Shanghai. Due to significant differences in infection rates between specific age groups and HPV subtypes, timely intervention is required for these vulnerable populations.
BackgroundS.aureus is a predominant pathogen that causes infection in critically ill patients, but little information exists regarding the characterization of S. aureus from different sources in burn patients in southeastern China.MethodsWe enrolled 125 patients with S. aureus infection in burns center between Jan 2014 and Dec 2015. S. aureus isolates were characterized by antimicrobial susceptibility test, toxin gene detection, and molecular typing with multilocus sequence type, staphylococcal protein A (spa) type, and staphylococcal cassette chromosome mec (SCCmec) type.ResultsSixty-eight MRSA were isolated from SSTI and 31 from non-SSTI patients, respectively. Overall, the drug-resistant ability of S. aureus isolated from SSTI was higher than that from non-SSTI groups. SCCmecIII-CC239-t030 was the most common clone (38 from SSTIs, and 8 from non-SSTIs). Seg was the most common enterotoxin gene (21 from SSTIs and 33 from non-SSTIs). Isolates from SSTIs was more likely to carry seb (P = 0.04), while those from non-SSTIs tended to carry sea and seg (P = 0.002 and 0.01, respectively). Although isolates carried four hemolysin genes, there was no significant difference between them (P > 0.05).ConclusionSCCmecIII-CC239-t030 was the most common clone in Jiangxi burns center, China. The molecular characterization of S. aureus was quite different between SSTI and non-SSTI groups.
