【摘要】 目的 观察低温等离子射频治疗阻塞性睡眠呼吸暂停低通气综合征（obstructive sleep apnea-hypopnea syndrome，OSAHS）合并变应性鼻炎的疗效。 方法 对2010年1－5月收治的42例OSAHS合并变应性鼻炎患者，采用低温等离子射频双下鼻甲减容、鼻腔内蝶腭神经及筛前神经末梢阻滞，并配合鼻中隔成形等手术。使用Epworth嗜睡评分量表（epworth sleepiness scale， ESS）和视觉模拟评分法（visual analogue scale，VAS）对治疗前及治疗3个月后的总体感受评分。 结果 ESS评分与VAS评分均符合正态分布，手术前、后ESS评分[（14.22±4.21）分，（6.78±4.12）分]与VAS评分[（8.34±2.72）分，（3.96±1.02）分]差异有统计学意义（Plt;0.05）。 结论 低温等离子射频治疗OSAHS合并变应性鼻炎疗效较好。【Abstract】 Objective To observe the clinical effect of treatment by low-temperature plasma radio frequency on obstructive sleep apnea-hypopnea syndrome (OSAHS) complicated with allergic rhinitis. Methods A total of 42 patients with OSAHS complicated with allergic rhinitis between January 2010 and May 2010 were chosen. All of the patients were treated by low-temperature plasma radio frequency nerve block, concha nasalis inferior ablation and other operations such as nasal septal construction. The nerve terminals of sphenopalatine nerve and anterior ethmoid nerve were blocked by ablation. Epworth sleepiness scale (ESS) and visual analogue scale (VAS) were used to estimate the curative effects. Results The results of ESS and VAS were consistent with gaussian distribution. There were statistical significant difference between the scores of pre-and post-operation (Plt;0.05). Conclusion The low-temperature plasma radio frequency treatment for OSAHS complicated with allergic rhinitis is easy，safe and efficient.
Cardiotocography (CTG) is a commonly used technique of electronic fetal monitoring (EFM) for evaluating fetal well-being, which has the disadvantage of lower diagnostic rate caused by subjective factors. To reduce the rate of misdiagnosis and assist obstetricians in making accurate medical decisions, this paper proposed an intelligent assessment approach for analyzing fetal state based on fetal heart rate (FHR) signals. First, the FHR signals from the public database of the Czech Technical University-University Hospital in Brno (CTU-UHB) was preprocessed, and the comprehensive features were extracted. Then the optimal feature subset based on the k-nearest neighbor (KNN) genetic algorithm (GA) was selected. At last the classification using least square support vector machine (LS-SVM) was executed. The experimental results showed that the classification of fetal state achieved better performance using the proposed method in this paper: the accuracy is 91%, sensitivity is 89%, specificity is 94%, quality index is 92%, and area under the receiver operating characteristic curve is 92%, which can assist clinicians in assessing fetal state effectively.
【摘要】 目的 探讨高压氧联合药物治疗突发性耳聋（sudden deafness， SD）的疗效。 方法 2008年2月-2010年7月，对174例SD患者采用高压氧（治疗压力0.2 MPa）及配合扩血管、营养神经等药物进行治疗，并观察其疗效。 结果 高压氧联合药物治疗SD总有效率为85.7％，SD的发病就诊时间是影响预后的主要因素，发病就诊时间≤7 d时，治疗有效率可达95.6%；≥15 d时，疗效明显降低。 结论 高压氧联合药物治疗SD疗效确切，且高压氧治疗越早疗效越好。 【Abstract】 Objective To observe the therapeutic effect of hyperbaric oxygen combined with medical treatment on sudden deafness. Methods Between February 2008 and July 2010, 174 patients with sudden deafness were treated by a combined therapy, including hyperbaric oxygen and medicals. The therapeutic effect was analyzed. Results The total effective rate was 85.7％. The simultaneous phenomenon such as vertigo and vomiting and onset-diagnosis duration were the two major factors affecting the prognosis. When the onset-diagnosis duration was ≤7 days, the effective rate reached 95.6%; when the onset-diagnosis duration was≥15 days, the therapeutic effect decreased significantly. Conclusion Hyperbaric oxygen combined with medical treatment is effective for sudden deafness, and the hyperbaric oxygen treatment should be performed as earlier as possible.
