目的:探讨运用临床路径护理声带息肉手术患者的护理效果。方法:将100例声带息肉患者随机分为两组,各50例。对照组按常规方法护理,观察组按临床路径实施护理。结果:观察组住院时间和住院费用少于对照组(P<0.05),患者健康教育知识评分和满意度高于对照组(P<0.05)。结论:临床路径为整体护理提供了更有效的指导,声带息肉手术推行临床路径,可以提高患者满意度,缩短住院时间、减少住院费用,从而有利于护理质量的提高。

目的 从流行病学角度了解宁波市北仑区噪声企业工人听力损失情况及个体听力对噪声的易感性差异.方法 对区内12家企业的噪声作业环境进行调查,对1 023名噪声作业工人进行职业卫生学调查和听力测定,由经过培训合格的调查人员进行问卷调查和纯音听力检查.结果 1 023名工人中共发现156名工人有不同程度的听力损失情况,其中高频听力损伤发生率为11.34%,高于语频听力损伤的发生率(4.79%),高频及语频听力损伤检出率在各工龄组间的差异无统计学意义(P ＞0.05).结论 本研究中未发现听力损失检出率及听力损失程度与接触噪声工龄有明显相关关系;个体听力对噪声易感性有显著差异.

目的探讨经鼻内镜鼻腔泪囊吻合术的临床效果。方法对17例慢性泪囊炎患者进行经鼻内镜鼻腔泪囊吻合术,术后随访6个月至3年。观察其疗效。结果治愈16例,无效1例。结论经鼻内镜鼻腔泪囊吻合术手术效果良好,是目前治疗慢性泪囊炎的最佳方法之一。

Objective The functional MRI(fMRI)was measured in the normal hearing Chinese subjects in responses to stimulations of different frequencies to investigate the tonotopic map in primary auditory cortex.Methods 25 healthy subjects with normal hearing were examined using tones of 500,2 000 or 4 000 Hz that were amplitude modulated(AM)sinusoidally at 8 Hz.The AM signals were presented at 96 dB SPL.Event-related design was combined with a sparse clustered volume acquisitioning paradigm for data collection in the attempt to reduce the influence of acoustic scanner noise.SPM2 software was used for offline data analyzing.Results Data from 9 subjects were discarded due to a large head movement during recording.In the rest 16 subjects,activation was found mainly in the primary auditory cortex.In many cases(6 left and 7 right hemispheres),a lateral-medial preference for low-to-high frequency response shift was clearly demonstrated in the primary auditory cortex.Conclusion Regarding stimulus frequencies,low-to-high frequency spatial gradients were observed along the primary auditory cortex in anterolateral to posteromedial direction,consistent with the presence of a tonotopic map in these primary areas.
