目的 探讨贵州地区进行宫颈癌机会性筛查的价值。 方法 回顾性分析2010年11月－2011年10月贵州省人民医院妇科门诊及住院进行宫颈癌机会性筛查的1 842例患者资料，筛查方法包括液基细胞学技术、宫颈刮片、人乳头瘤病毒（HPV）分型检测、HPV第2代捕获杂交法检测、阴道镜检查，以病理确诊宫颈癌前病变及宫颈癌。 结果 贵州地区女性人群的HPV平均感染率为21.87%。共检出宫颈癌前病变39例（2.12%），宫颈癌2例（0.11%）。 结论 医院内就诊女性宫颈病变检出率高，应高度重视其机会性筛查，有助于早期干预治疗。
To explore the feasibility of applying magnetic stimulation technology to the movement control of animal robots, the influence of coil radius, number of turns and other factors on the intensity, depth and focus of magnetic stimulation was simulated and analyzed for robot pigeons. The coil design scheme was proposed. The coil was placed on the head and one of the legs of the pigeon, and the leg electromyography (EMG) was recorded when magnetic stimulation was performed. Results showed that the EMG was significantly strengthened during magnetic stimulation. With the reduction of the output frequency of the magnetic stimulation system, the output current was increased and the EMG was enhanced accordingly. Compared with the brain magnetic stimulation, sciatic nerve stimulation produced a more significant EMG enhancement response. This indicated that the magnetic stimulation system could effectively modulate the functions of brain and peripheral nerves by driving the coil. This study provides theoretical and experimental guidance for the subsequent optimization and improvement of practical coils, and lays a preliminary theoretical and experimental foundation for the implementation of magnetic stimulation motion control of animal robots.
