利用人 耳有限元数值模型研究了鼓膜置管对鼓膜及镫骨底板振动的影响，分析了置管自身振动情况。

Results: The satisfactory MPR images of cochlea, bony semicircular canals, internal auditory meatus and other intratemporal structures can be obtained. The SSD images could show some important bony marks of temporal bone and spatial relationships between them clearly. On coronal plane, SSD images can vividly demonstrate the shape and spatial relationships of malleus and incus. A series images were obtained as the virtual endoscope moved from the external auditory canal to the middle ear cavity.

结果：MPR能在不同切面显示耳蜗、半规管、内耳道及面神经管垂直段等结构，显示率为100%；SSD能清晰显示颞骨重要的骨性结构，如内耳门、颈静脉孔等，冠状位切割后的SSD图像能生动地显示锤骨、砧骨的立体形态及空间关系；CTVE可模仿内窥镜从外耳向中耳移动，清晰显示骨性外耳道、鼓室内侧壁及听骨链等结构。

Dynamic ET endoscopy findings of 121 ears (of the total 124 ears studied) were correlated with middle ear manometric studies using Mc Nemar 2 test.

这表明（内镜下共研究了124例耳）所发现的121例耳的咽鼓管动态与用Mc Nemar 2测试检测的中耳测压研究显著相关。

And at both the lateral semicircular canal and superior semicircular canal in 2 ears.

外半规管和上半规管同时有瘘管2耳。

Objective To study the relationship of endangium proliferation and the expression of metalloproteinases and tissue inhibitors of metalloproteinases after angioplasty of iliac artery in rabbits to investigate the probable mechanism of composite Danshen pill in prevention and treatment of restenosisMethods 30 white male rabbits of Japan （the average body weight was 25～30 kg）were randomly divided into 3 groups:normal control group,model group (intima destroyed by balloon and given hypercholesterol diet),CDP group (intima destroyed by balloon and given hypercholesterol diet plus drug CDP 150 mg/d),10 ones each groupResults The results of iliac artery angiogram and the analysis of pathology:there were lumens stenosis,thinner intima,smaller intima area,in CDP group compared with those in model group,and ratio of intima and tunica media thickness and area among each group (P＜001)Immunohistochemistry analysis:the MMP2,MMP9,TIMP1,TIMP2 in model group significantly increased than those in control group (P＜001)The CDP group had lower MMP2 and MMP9 expression,higher TIMP1 and TIMP2 expression,and increased MMP2/TIMP1,MMP9/TIMP2 than model group (P＜001)The thickening of vascular neointima and stenosis degree of vascular lumen were relevant to MMP2 and MMP9 (r=0896,P＜001)Conclusions MMP and TIMP play the very important role in the restenosis process of arteryCDP could inhibit the thickness of vascular neointima after balloon injury,the probable mechanism of which may be inhibiting collagen formation,smooth muscle immigration and decreasing hyperplasia of intima by interfering expression of MMPs and TIMPs

目的 研究兔髂动脉成形术后血管内膜增生和基质金属蛋白酶及其抑制物表达之间的关系，探讨复方丹参滴丸预防再狭窄的可能机制。方法健康成年二级雄性日本大耳白兔30只，平均体重25～30 kg。随机分为3组：正常对照组10只，模型组10只（球囊内膜剥脱加高胆固醇饮食），治疗组10只（球囊内膜剥脱加高胆固醇饮食以及复方丹参滴丸150 mg/d）。结果兔髂动脉造影、血管病理图像分析检测结果：①复方丹参滴丸组较模型组血管造影示管腔直径狭窄、内膜厚度减少、内膜面积减少、内膜厚度和中膜厚度比、面积比，各组之间有显著性差异(P＜001)。②免疫组化分析：模型组MMP2、MMP9、TIMP1、TIMP2表达均高于对照组（P＜001）；复方丹参滴丸组MMP2、MMP9的表达低于模型组，而TIMP1、TIMP2的表达高于模型组；TIMP1/MMP2、TIMP2/MMP9明显增加，差异有显著性（P＜001）。③内膜的增生以及管腔的狭窄程度与MMP2、MMP9有很好的相关性(r=0896，P＜001)。结论 MMP和TIMP在再狭窄形成中起重要作用；复方丹参滴丸能够明显抑制血管损伤后的内膜增生，可能的机制是通过影响金属蛋白酶MMP2、MMP9及其抑制物TIMP1、TIMP2的表达从而抑制胶原的生成、平滑肌的迁移、增生，而减少内膜的增生。

And children may suffer airplane air more easily than adults because their Eustachian tubes are small and easily blocked.

儿童比成年人更容易得飞机耳，因为他们的耳咽管小，容易堵塞。

Objective To analyze the therapeutic effects of myringotomy supplemented with grommet insertion on adults with secretory otitis media.

作者：刘大顺，范永杰，董潇，郝艳芬、目的分析鼓膜置管对成人分泌性中耳炎的疗效。方法回顾性分析成人100例（162耳）分泌性中耳炎鼓膜置管术的疗效。

Methods Thirty-four ears with traumatically perforated tympanic membrane and 57 ears of secretory otitis media with incised tympanic membrane were selected.
