High prevalence of syphilis among street-based female sex workers in Nanchang, China.

Background: Female sex workers (FSWs) play a critical role in the heterosexual transmission of human immunodeficiency virus (HIV)/sexually transmitted infections (STIs) in China. Several studies reported that street-based FSWs have higher risk behaviors than establishment-based FSWs. Therefore, street-based FSWs should be specifically targeted for HIV and STIs intervention programs.

Efficacy and safety of photodynamic therapy for cervical intraepithelial neoplasia: a systemic review.

Background: The current treatment of cervical intraepithelial neoplasia (CIN) is primarily based on surgical excision using laser, a loop electrosurgical procedure, or a cold knife technique. Unfortunately, these treatments often lead to obstetrical problems during the subsequent pregnancy, particularly in young women. Photodynamic therapy (PDT), which uses a topical or intravenous photosensitizer (PS) activated by a light source to ablate abnormal tissue, offers a minimally invasive alternative.
