Background: Maternal infection during pregnancy is known to adversely affect foetal development, but previous studies have rarely investigated the impact of gynaecological diseases during pregnancy on offspring during adulthood. Vaginitis is one of the most prevalent gynaecological diseases during pregnancy.
Methods: The effect of maternal vaginal inflammation on offspring was simulated by inducing maternal vaginal infection.
Background: The recent emergence of azithromycin-resistant (AZM-R) N. gonorrhoeae isolates that have coevolved decreased susceptibility to extended-spectrum cephalosporins has caused great concern. Here we investigated the prevalence of decreased susceptibility to ceftriaxone (CRO(D)) in AZM-R isolates and genetically characterized AZM-R isolates in Guangzhou, China from 2009 to 2013.

- - A study examined 1224 Neisseria gonorrhoeae isolates from Guangzhou over two periods (2000-2005 and 2008-2013) for antimicrobial susceptibility.
- - Resistance to penicillin increased from 71.1% to 90.9%, and resistance to ciprofloxacin rose from 88.9% to 98.0% during the study.
- - Despite rising minimum inhibitory concentrations, all isolates were still susceptible to spectinomycin and ceftriaxone.
Objective: To observe the changes in peripheral blood lymphocyte subsets in patients with latent syphilis after treatment, who had persistent positive results of test for rapid plasma reagin (RPR) and remained infectious.
Methods: T-lymphocyte subsets and natural killer (NK) cells in peripheral blood were measured with flow cytometry (FCM) in these 43 patients and 30 normal subjects served as controls.
Results: Peripheral blood CD3, CD4 and NK cells exhibited no significant difference between the latent patients and the controls (P>0.
