Association of C722T polymorphism in XRCC3 gene with larynx cancer: a meta-analysis.

Several case-control studies indicated that XRCC3 genetic polymorphism (C722T) was associated with larynx cancer. The present study aimed to further evaluate the relation between the XRCC3 gene C722T polymorphism and larynx cancer. We selected five case-control studies related to XRCC3 gene C722T polymorphism and larynx cancer by searching PubMed, EMBase, Chinese CNKI, and Wanfang database.

[Observation of bacterial biofilms in patients with chronic rhinosinusitis].

Objective: To explore the presence of bacterial biofilms (BF) in patients with CRS and the effect of BF on clinical symptoms and postoperative outcomes.

Methods: Seventy-two patients with chronic sinusitis were enrolled in this study. The control group included 15 patients with deviation of the nasal septum and 10 patients had a fracture of the nasal bone.
