听小骨

Results Among these cases,the main CT features of the tympanic cholesteatoma included:soft tissue density tumor shadows in the tympanic sinus and cavity;bone destruction;sclerosis of the bone borders of tympanic sinus and cavity;destruction and shifting of the auditory ossicle chain.

结果 该组病例中，胆脂瘤性中耳炎的CT主要表现有：中耳窦腔内软组织密度瘤影；骨质破坏；中耳窦腔骨缘硬化；听小骨链破坏、移位。

Results HRCT findings of 45 cases of chronic otitis media with cholesteatoma included abnormal soft-tissue mass shadows in tympanic cavity of middle ear,sclerotic mastoid were observed in most cases, and bone changes including enlargment of the tympanic cavity with sclerotic border, the dislocation and destruction of the ossicles.The sigmoid sinus plate,tympanic tegmen, semicircular canal and facial nerve canal were destroyed in severe cases.

结果 胆脂瘤型慢性中耳炎患者HRCT表现：①45例均见中耳腔内团块状软组织影；②40例为硬化型乳突（88.9%）；③骨质改变包括中耳腔扩大和周缘骨质硬化、听小骨的移位、破坏、乳突骨质的破坏，严重者可伴有乙状窦壁、鼓室盖、面神经管及半规管的破坏。

Results Spiral CT findings of cholesteatomtous tympanitis included: soft tissue mass in the tympanium, tympanal sinus and mastoid,destruction of the bone including ossicles chain,secutum,facial nerve canal,semricirular canal,sigmoid sinus plate, tegmenttympanic.

结果：胆脂瘤型中耳炎的螺旋CT表现为鼓室、鼓窦及乳突区软组织肿块，常伴有骨质破坏，其中包括听小骨、盾板、面神经管、半规管、乙状窦及鼓室盖骨质破坏。

The most common form of these ossicular chain lesions following head injury is incudostapedial joint separation.

听小骨链断离的型式以砧骨磴骨关节分离（incudostapedial joint separation）最为常见。

An intact ossicular chain was found in 72% of the cases and could often be presered at surgery.

有72％病例可见完整的听小骨链，并且通常能在外科手术中予以保存。

Correlations between the above indexes and between the above indexes and the degree of ossicular destruction were investigated.

二者在胆脂瘤上皮的表达有一定的相关性，P＜0.05；与中耳胆脂瘤听小骨骨质破坏程度之间无明显相关性，P＞0.05。

Correlations between the above indexes and between the above indexes and the degree of ossicular destruction were investigated.

采用免疫组织化学技术SABC法检测CDK4、P16在中耳胆脂瘤35例、正常外耳道皮肤20例中的表达，并结合胆脂瘤对听小骨骨质破坏程度，采用SPSS11.5软件进行统计学分析。

The most common form of ossicular chain lesion following head injury is incudo-stapedial joint separation.

听小骨链断离的形式以砧骨镫骨关节分离(incudo-stapedial joint separation)最为常见。

Objective:To observe the morphology of eroded auditory ossicles obtained in middle ear surgery for cholesteatoma and to investigate the mechanism of bone erosion in cholesteatoma.

目的：观察胆脂瘤破坏听小骨的形态学结构变化，探讨胆脂瘤的骨质破坏机制。

The destruction of ditus ad antrum and ossicles is the due to the diagnosis of cholesteatoma. The development of the two side mastoid can be imcompatible.

CT发现听小骨和鼓窦人口破坏多提示胆脂瘤；双侧乳突发育可不一致。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
