目的:探討B超檢查對急腹癥的臨床應用價值。方法:回顧性分析326例急腹癥的超聲表現并與手術后、病理診斷以及隨訪結果進行對照。結果:326例急腹癥中以急性膽囊炎、輸尿管結石、急性闌尾炎以及婦科急癥常見,共289例,占88％,其他急腹癥37例,占12％。經手術和病理證實217例,109例臨床隨訪證實。超聲符臺率89.9％。結論:B超檢查對急腹癥的早期診斷以及鑒別診斷具有重要臨床意義,是急腹癥首選的診斷方法。
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.
