单侧听神经病1例

目的 分析单侧听神经病的听力学特征,探讨其病损部位.方法 对单侧听神经病患儿的临床资料、纯音测听、声导抗测试、畸变产物耳声发射（distortion product otoacoustic emission, DPOAE） 、听性脑干反应（auditory brain stem response ,ABR）的听力学测试结果进行分析.结果 患耳（右耳）纯音听力图为缓降型,听力损失为重度感音神经性聋,健耳（左耳）听力正常;患耳的同侧及对侧镫骨肌声反射未能引出,健耳的同、对侧声反射均能引出 .患耳的听性脑干反应各波未能引出,健耳的ABR各波潜伏期正常 .双耳 DPOAE各频率均正常引出.颞骨高分辨率CT未见异常.结论 单侧听神经病的听力学特征与双侧听神经病的听力学特征基本相同.但单侧听神经病以重度聋较多见,应对单侧感音神经性聋患者进行全面的听力学检测 ,需注意与一般单侧感音神经性聋相鉴别.DPOAE 及ABR 对诊断、鉴别诊断具重要意义.

目的探讨大前庭水管综合征与儿童突发感音神经性耳聋的关联及临床特点、听力学、影像学改变与治疗。方法对35例儿童大前庭水管综合征患者临床资料进行分析总结。结果本研究均为无原因的突发感音神经性聋,听力学检查中发现,均为高频重度感音性聋,其中56耳患儿在250、500Hz均存在有气骨导差,气骨导差>15dBHL,以250dBHL最为明显,经过多次复诊,多数听力波动性进行性加重。结论大前庭水管综合征是内耳畸形的听力障碍性疾病。可依靠听力学检查、CT和MRI明确诊断。     

咔嗒音刺激所致的前庭诱发肌源性电位研究

目的:通过咔嗒音刺激于颈肌(胸锁乳突肌)记录前庭诱发肌源性电位(VEMP),探讨VEMP对前庭功能障碍的诊断价值及其发生机制.方法:选取周围性和中枢性前庭功能障碍28例,采用丹迪Keypoint肌电图仪,分别记录P13-N23-N34-P44复合电位.另选正常对照组22例作对照,结果:正常者,在同侧可记录到复合电位P13-N23-N34-P44,初期成分P13-N23全部都有,2例后期成分N34-P44不明显.听力有极度损失的,该电位也能记录.而有严重前庭功能障碍的患者,该电位不能记录或者波形分化不完全,P13潜伏期延长.听力基本保留的听神经肿瘤患者,该电位不能记录,或者波形分化不完全,P13潜伏期延长.4例延髓背外侧综合征患者,P13延长.结论:VEMP不是从耳蜗神经而来,而是从前庭神经,尤其是球囊、斑而来.该检查法,对前庭功能,尤其是球囊、斑功能的定量评价有一定的价值,可作为一个新的检查方法.

Survey and practice of reporting quality of randomized controlled clinical trials on traditional Chinese medicine

Evidence obtained from randomized controlled trials （RCTs） has been generally accepted as the gold standard in the evaluation of clinical effectiveness. Readers need to understand the trial design, implementation, results, analysis and interpretation, so as to fully Jnderstand the results of RCTs. Thus, the investigators of RCTs have to report these items in a complete, accurate and clear manner. Since 1998, we have conducted several evaluations on the reporting quality of RCTs published in Chinese journals on traditional Chinese medicine （TCM） and results have shown that there is an urgent need for higher quality RCTs on TCM.     

TCM Treatment of Ankylosing Spondylitis by Tonifying the Kidney and Strengthening the Governor Vessel

Ankylosing spondylitis is a chronic and progressive disorder with inflammation mainly involving the central axis joints. It mainly affects the cervical spine and the lumbosacral area, with the pathogenesis closely related to the kidney and the Governor Vessel (GV). TCM holds that the syndrome is deficiency in origin and excess in superficiality, which is due to insufficiency of the kidney, deficiency of GV, and blocking of the channels with the invasion of exogenous evil, leading to poor circulation of qi and blood and malnutrition of the bones, muscles and joints. The TCM method of tonifying the kidney and strengthening GV to regulate circulation of qi and blood and check the arthralgia pain should be adopted, with the Kidney-Tonifying and GV Strengthening Decoction (益肾强督汤) prescribed.
