Objective: To perform a Meta-analysis of all randomized controlled trials that compared the efficacy and adverse events profile of Mabs for LA HNSCC., Method: Several databases were searched, including CBM, PUBMED, EMBASE, and CENTRAL. Primary outcomes included overall response rate (ORR), overall survival (OS), progression-free survival (PFS). Secondary outcomes included serious adverse events, such as grade 3-4 skin reaction, dysphagia, mucositis, and nausea/vomiting. The results were expressed as relative ratio (RR) or hazard rate (HR) with their corresponding 95% CI., Result: The final analysis included 10 trials. The primary analyses indicated that Mabs did not improve ORR and PFS, except OS for locoregionally advanced (LA) HNSCC [ORR 1.21, 95% CI (0.97 - 1.49); PFS 0.87, 95% CI (0.75 - 1.01); OS 0.82, 95% CI (0.71 - 0.95)]. Analysis of adverse effects demonstrated that grade 3 - 4 skin reaction ERR 1.87, 95% CI (1.11 - 3.16)] was statistically significantly associated with Mabs except dysphagia ERR 0. 95, 95% CI (0.75 - 1.19)], Mucositis ERR 1.03, 95% CI (0.67 - 1.57)], and nausea/vomiting ERR 1.15, 95% CI (0.71 - 1.86)]., Conclusion: Anti-EGFR Mabs may be satisfactory for improving OS of LA HNSCC. During the Mabs therapy, skin reaction should be much more monitored.

Objective: To evaluate the clinical application value of nasal airway obstruction objectively and quantificationally by acoustic rhinometry (AR) in children with adenoid hypertrophy., Method: Thirty patients with adenoid hypertrophy were examined with AR and questionnaire at preoperative and eight weeks after surgery. The values of AR were compared with those of 27 normal controls., Result: There were significant differences between preoperative and postoperative in NAR and NPV (P < 0.01), no significant difference was observed between preoperative and postoperative in MCSA (P > 0.05); There were significant differences in NAR, NPV, MCSA between the patient group and the control group (P < 0.01); There were significant differences between postoperative and the control group in NPV and MCSA (P < 0.01), no significant difference was observed between postoperative and the control group in TNAR (P > 0.05); There was negative correlation between MCSA and symptom scores (r = -0. 519, P < 0.05). No significant correlation was observed between NAR and NPV and symptom scores (P > 0.05)., Conclusion: Acoustic rhinometry was an objective and quantitative method for evaluating nasal airway in children with adenoid hypertrophy. In interpretation the relationships of the results of acoustic rhinometry reflection measurements and subjective symptoms, MCSA should be the main reference.
