目的 探讨职业性噪声暴露对广州市黄埔区某企业噪声作业工人听力损失状况的影响。方法 观察2016年8月—2018年8月,广州市黄埔区某企业噪声作业工人年度职业健康体检1 600例为调查对象,对该群体的纯音听阈测试检查结果进行分析。结果 随工龄不同听力损失发生率相比,差异有统计学意义(P<0.05),还会随着工龄的增长而增加听力损失几率;佩戴听力防护用品工人听力损失发生率低于不佩戴听力防护用品的工人,差异有统计学意义(P<0.05)。结论 噪声作业工人工龄时间越长听力损失发生率越高,防护听力用品的使用可有效降低听力损伤发生率,故在噪声作业时,企业应做好听力损伤防护措施,保障工人身心健康。

目的 探讨两种不同手法复位治疗向地性眼震水平半规管良性阵发性位置性眩晕的临床效果。方法 选取水平半规管良性阵发性位置性眩晕患者50例,分组进行不同手法复位治疗,短期治疗效果不佳者结合强迫长时间健侧卧位法治疗。结果 初次治疗360-Barbecue复位法组治愈率80%,Gufoni复位法组患者治愈率72%;两组患者结合强迫长时间健侧卧位法,第二天复查治愈率分别为92%和88%,两组比较差异无统计学意义(P>0.05)。结论 两种手法复位均能有效治疗向地性眼震水平半规管良性阵发性位置性眩晕,近期疗效相近,对于无效者结合FPP可增加治愈率。

Objective To study the effects of two different manual reduction of geotropic nystagmus horizontal semicircular canal benign paroxysmal positional vertigo. Methods 50 cases of patients with two different groups, treated with different manual reduction. Patients with short term treatment but ineffective were treated in combination with forced prolonged lateral position FPP. Results The cure rate of initial treatment in the 360-Barbecue manual reduction groups was 80%, the Gufoni manual reduction groups was 72%. As the patients combined with FPP, the cure rate was 92% and 88% respectively in the second day treatment. There was no significant difference between the two groups(P>0.05). Conclusion Both of the different manual reduction may effectively treat HC-BPPV. Their recent curative effect is similar. For ineffective cases may increase the cure rate combined with FPP.
