目的:探讨B超检查对急腹症的临床应用价值。方法:回顾性分析326例急腹症的超声表现并与手术后、病理诊断以及随访结果进行对照。结果:326例急腹症中以急性胆囊炎、输尿管结石、急性阑尾炎以及妇科急症常见,共289例,占88％,其他急腹症37例,占12％。经手术和病理证实217例,109例临床随访证实。超声符台率89.9％。结论:B超检查对急腹症的早期诊断以及鉴别诊断具有重要临床意义,是急腹症首选的诊断方法。
Due to the decline of motor ability and the impact of the diseases, abnormalities in gait is common in the elderly population, which will raise the risk of fall and cause serious injury. This study focuses on the analysis of the gait kinematics parameters of normal adults’ gait, aiming to investigate the characteristics of gait parameters in different age groups and to explore the role of gait parameters in motor function assessment and clinical diagnosis. Based on the gait data gained by electronic walkway, the relationship among the toe out angles and their correlation with age and gender etc. were quantitatively analyzed. The results show that most normal subjects walk with positive toe out angles, and the angles increase with age. Such changes are slow in the young and middle age groups. However, the elevations of the left out toe angle and the angles between the feet are statistically significant after entering elder age ( >60 years). The results also suggest that the angle between the feet is a kind of practical gait parameter for varying applications. This study concludes that feet angle analysis is potential to provide a convenient and quantitative tool for the assessment of lower limb motor ability and the diagnosis of knee joint diseases.
