Results Women were more often affected than men(1.83:1) and 53 patients were older than 40 years. The involved parts were as follows: eyelid 58 cases (89.2%), mouth and mandibula 46 cases(70.8%),neck 17 cases(26.2%). The symptom at onset were blepharospasm 42 cases(64.6%) or oromandibular dystonia 17 cases(26.2%).In part of the patients, cranial MRI examination could find focus in brainstem or basal ganglia. Among 37 patients treated with oral drugs, 4 cases were almost cured, 16 cases improved and 17 cases showed no effect. While in 15 patients treated through chiostridium botulinum toxin injection, 5 were almost cured, 9 improved and 1 had no effect.

Detailed history collection, physical examination and systematic audiological evaluations were conducted. The later included pure tone audiometry, acoustic immittance, auditory brainstem response, cochlear microphonics, and evoked otoacoustic emissions. Two hearing-impaired cases received 2 years?

对23名家系成员（直系亲属21人，配偶2人）进行病史采集、体格检查及系统的听力学检测，包括纯音测听、声导抗、听性脑干反应（auditory brainstem response， ABR）、耳蜗微音器电位（cochlear microphonics， CMs）及诱发性耳声发射（evoked otoacoustic emissions， EOAEs）。

Auditory Brainstem Response, ABR (or Brainstem Auditory Evoked Potentials, BAEP) is a human body physiology parameter at microvolt level. First, we use the TMS320F2812 of TI company, making the signal through D/A transform and high accuracy operational amplifier, and produce the masking white noises, as well as the Tone Burst to be the stimulus. Then, the evoked EEG will be amplified and filtered. At the same time, we use the A/D of TMS320F2812 to collect and process the signals, and get the digital BAEP.

听觉脑干诱发电位(Auditory Brainstem Response，ABR)为微伏级人体生理参量，采用TI公司的DSP TMS320F2812，通过D/A与高精度运算放大器，生成听力级可调整的掩蔽白噪声与短纯音TB进行刺激，同时对诱发脑电进行放大、滤波、并使用TMS320F2812的A/D进行信号采集与处理，得到数字化的脑干诱发电信号。

The model of brain concussion of rat can be established successfully using iron pendulum hitting device; 2. The spatial learning and memory deficits of the rats are detected by MWM in early period post-BC(from 1 to 3 days after BC); 3. Pycnosis degeneration or necrosis neurons of the cerebral cortex, dorsal hippocampus, dentate fornix and brainstem reticular formation are identified in BC rats; 4. There are significantly changes in the number and activity of cholinergic neurons in the basal forebrain and brainstem reticular formation after BC; 5. The change of cerebral neurons and cholinergic neurons correlate with cognitive deficits in BC rats .

Methods: A brain concussion was produced in rats using a simple pendulum device model. One control (n=12) and six experimental groups were used(n=12 in each group). The cerebral concussion groups were assigned to sacrifice times ranging from 1 day to 24days after injury.A Morris Water Maze memory paradigm was used to assess learning and memory function. Pycnosis degeneration or necrosis neurons in the locus cerebral cortex, dorsal hippocampus, dentate fornix and brainstem reticular formation were observed and counted after brain concussion. Cholinergic neurons in the basal forebrain and brainstem reticular formation were identified and quantitated using choline acetyltransferase.
