Results All the children and their parents received interviews, otological examinations and clinical audiolugical teats. Their ages were between 4 and 15, with the average at 9.51±2.83.①The males were 341 (61.66%) and female 212 (38.34%), with the gender ratio of male to female as 1.61:1.②The peak of the age curves of treatment and the first onset of vertigo was 9.51 and 8.62-year-old, respectively.③20.98% of children with vertigo had normal results with peripheral vertigo more common in the rest.④ The semicircular canals were more likely to dysfunction if their relatives had vertigo or car sickness.

结果 ①553例儿童年龄4~15岁，平均9.51±2.83岁；男341例(61.66%)、女212例(38.34%)，男女之比为1.61：1；②就诊年龄和初次眩晕发病年龄的高峰期分别在9.51岁和8.62岁，发病无季节性，主要症状为自身或视物旋转，发作持续时间为数分钟至数小时；③约20.98%的儿童眩晕患者各项检查结果均正常，异常组中以外周性眩晕多见(78.04%， 341/437)，半规管功能异常者占63.83%(353/553)；④256例眩晕儿童直系家属中有眩晕史，其中171例(66.80%)出现水平半规管功能异常。

A acute partial obstructive hepatocholangitis model by selective ligation and injection of E coli into left hepatic bile duct was successfully founded in rat. Using parameters including mortality, mitochondrial glutamic oxalacetic transaminase and ornithine carbamoytransferase activity, pathological observation and blood culture of bacteria, we evaluated the model.

作者采用选择性左肝管穿刺注菌法成功地建立了Wistar大鼠急性部分肝胆管梗阻感染的脓毒症模型，并从胆管系统形态学、累计病死率、血清线粒体谷草转氨酶和鸟氨酸氨基转移酶活性、多器官大体病理观察以及血液细菌培养几方面对该模型的科学性、重复性进行了评估。

A novel hybrid diode-clamp cascade multilevel converter is presented in this paper. The new concept of the converter is based on connection of multiple diode-clamp converter modules with different dc bus voltages. Normally, the voltage blocking capability of faster devices such as IGBT and the switching speed of high voltage devices like GTO are found to be limited.
