RESUMO
Objective To evaluate the clinical efficacy of nasal endoscope-assisted low temperature plasma adenoidectomy. Methods 100 patients who underwent adenoidectomy from May 2012 to August 2016 were enrolled in the study. All the patients were randomly divided into the observation group (50 cases) and control group (50 cases). Patients in the observation group underwent nasal endoscope-assisted low-temperature plasma adenoidectomy, and patients in control group was treated with nasal endoscope-assisted electric adenoidectomy. The operation time, bleeding volume, recovery time of nasal ventilation, clinical efficacy, postoperative complications of the two groups were analyzed and compared. Results In the observation group, the operation time, bleeding volume, recovery time of nasal ventilation was (4.9 ± 1.6) min, (19.6 ± 5.6) ml and (2.9 ± 0.5) d, respectively, which was significantly less than that of the control group (11.9 ± 3.9) min, (61.6 ± 12.1) ml and (5.9 ± 1.6) d, respectively (P < 0.05). The clinical efficacy of the observation group and the control group was 92.0%, and 86.0%, there was no significant difference between the two groups (P > 0.05). In the observation group, the pain index was (1.8 ± 1.0), which was significantly lower than that of the control group (5.6 ± 2.1), the difference was statistically significant (P < 0.05), and there was no significant difference with respect to postoperative hemorrhage, fever and snoring (P > 0.05). In addition, there was no postoperative complication observed in the observation group, while, the complication rate of the control group was 10.0%, the difference between the two groups was statistically significant (P < 0.05). Conclusion Nasal endoscope-assisted low temperature plasma adenoidectomy is effective and safe in the treatment of adenoid hypertrophy with less pain and fewer complications, which can be used as a routine clinical treatment for adenoid hypertrophy in children.

RESUMO
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. RevMan 5.0 software was used to perform the analysis. We directly utilized Q test and I (2) test to test the heterogeneity between each study. We utilized the fixed effects model to merge the odds ratio (OR) and 95 % confidence interval. There were 1,507 larynx cancer patients and 3,623 cancer-free control subjects included in the present study. By meta-analysis, we did not find any association of XRCC3 gene C722T polymorphism with larynx cancer [OR=1.54, 95 % CI (0.77-3.08); P=0.22]. The present study indicated that XRCC3 gene C722T polymorphism was not associated with larynx cancer.

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. Mucosa of the uncinate process or ethmoid near the ostium of the maxillary sinus was obtained during endoscopic sinus surgery. The specimens were subjected to scanning electron microscopy. Patients were followed for 1 year and observed by the Lund-Kennedy endoscopy, and the Haikou standard classification (ESS-1997). Statistical analysis was performed by t-test or chi-square test. RESULTS: Three patients were lost to follow-up. The scanning electron microscopy analysis showed bacterial biofilms in 49 of the 69 patients with chronic sinusitis. A marked destruction of the epithelium and cilia was observed in samples positive for bacterial biofilms. No bacterial biofilms were detected in the control group, and scanning electron microscopy showed normal epithelium and cilia in those specimens. There was no significant difference in gender, classification or duration of disease between the BF(-) and BF(+) groups. At six months and one year postoperative, the Lund-Kennedy endoscopy scores for CRS patients with BF (4.78 +/- 1.67; 4.55 +/- 1.61) were significantly higher than those without BF (3.65 +/- 1.39; 3.65 +/- 1.18) (t = -2.654, P < 0.01; t = -2.264, P < 0.05). Based on the Haikou standard classification, there was a significantly difference between patients with BF and those without BF (chi2 = 18.014, 22.063, P < 0.001, respectively). CONCLUSIONS: Different life stages of bacterial biofilms were demonstrated to be present in CRS. Gender, classification or duration of disease did not affect the presence of bacterial biofilms in patients with CRS. There is a correlation between bacterial biofilms and an unfavorable outcome in patients with CRS after ESS.
