电刺激诱导前庭电位

OBJECTIVE: To identify the evoked potentials (VsEPs) by electrical stimulation were from vestibule. METHODS: The stimulating electrode was set on the round window of guinea pig. Constant current shocks of 0.05 ms (0.25-1.2 mA) were used to evoke VsEPs by means of vertex-pinna skin electrodes. RESULTS: These potentials were short latencies of (0.973 +/- 0.086) ms, (1.618 +/- 0.176) ms and (2.416 +/- 0.274) ms respectively, which reflected true potentials and were not from electrical stimulus artefacts. It was pure vestibular origin. As being masked with a continuous white noise (120 dB SPL) or removed ipsilateral auditory nerve, and even after facial neurectomy, waves were still existing, but disapeared after selective vestibular neurectomy. The twitching responses in the facial region had never been detected during the whole test. These potentials were bioelectric responses in the vestibular sensory pathway, characterized by threshold saturation, adaptability of excitation, dependent on intact vestibular nerve. CONCLUSIONS: We have set up animal model of recording VsEPs evoked by electrical stimulation on the round window of guinea pigs.

舌下针治疗中风(缺血性)的疗效及血液流变学变化的观察

：以舌下针对70例中风（缺血性）患者进行针刺治疗,观察到针刺后患者的全血比粘度（包括全血还原比粘度）、红细胞压积、血沉、红细胞电泳时间以及血浆比粘度等指标均有降低,其差异经统计学处理有非常显著意义（P＜0.01）,可见用舌下针针刺后．患者血液的浓稠性、凝固性、粘滞性、聚集性均较针刺前有显著改善,这表明针刺后能使血液粘度降低、血管阻力减弱、血液流动加快、血流量增加．从而改善了中风（缺血性）患者的脑部的血循环,这对患者的治疗无疑是大有裨益的。     

离子通道门控动力学研究

报道作者近期在离子通道动力学方面所作的研究工作。以膜片钳记录信号的自相关函数为基础,证实了离子通道记忆性的存在,并提出两状态非线性随机模型和镶嵌点过程模型,用于描述记忆性和门控动力学的特征,这样做可以克服Ｍａｒｋｏｖ模型和分形模型所遇到的３项困难,即状态不可辨认性、开关判定的主观性和时间间隔疏漏。另外,作者还提出了连续分组平均时间检测法,帮助确定Ｍａｒｋｏｖ模型中状态的个数,与多指数拟合法相比,此方法更直观和易于操作     

Transcutaneous vaccines: novel advances in technology and delivery for overcoming the barriers

Transcutaneous immunization represents an attractive alternative to vaccine delivery via topical administration and has received wide attention due to its easy-to-use, needle-free and noninvasive delivery. However, the development of transcutaneous vaccine was kept a challenge because of the barrier function of stratum corneum which inhibits the transport of antigen and adjuvant. Nowadays, pharmaceutical methods and novel physical devices are extensively investigated to overcome the penetration barrier of the stratum corneum for transcutaneous vaccine. In this article, these pharmaceutical methods and novel devices used for the enhancement of transcutaneous immunization were reviewed. In addition, chemokines promoted the migration of Langerhans cells and the transcutaneous adjuvants enhancing the immune responses at certain levels are also discussed for the development of novel transcutaneous vaccines.
