Hemodynamics plays a vital role in the development and progression of cardiovascular diseases, and is closely associated with changes in morphology and function. Reliable detection of hemodynamic changes is essential to improve treatment strategies and enhance patient prognosis. The combination of computational fluid dynamics with cardiovascular imaging technology has extended the accessibility of hemodynamics. This review provides a comprehensive summary of recent developments in the application of computational fluid dynamics for cardiovascular hemodynamic assessment and a succinct discussion for potential future development.
The precise anatomical division of liver segments is the foundation of liver surgery, while the anatomical division of the S9 segment of liver is a further precise division of the caudate lobe of the liver. This article retrospectively analyzed and summarized the precise minimally invasive ablation and follow-up results of four representative lesions of the S9 segment of liver, including primary liver cancer, recurrent liver cancer, metastatic liver cancer, and focal liver hyperplasia, treated at Affiliated Dongguan Hospital of Southern Medical University. The aim of this study is to explore the minimally invasive ablation effect of lesions located at the S9 segment of liver under CT guidance.
目的 探讨联合脑卒中单元在老年脑卒中患者中应用研究。 方法 选择2003年7月－2011年7月在我院住院的60岁以上的260例急性脑卒中患者，随机分为联合脑卒中单元组和普通病房治疗组各130例，两组均采用常规内科或手术治疗，联合脑卒中单元组除常规内科或手术治疗外，入院后病情平稳24～48 h后偏瘫患者给予运动康复训练，吞咽障碍患者给予吞咽康复训练，抑郁患者给予心理康复治疗3个月。对联合脑卒中单元/普通病房治疗两组患者在治疗前及治疗后分别采用改良的巴氏指数测定日常生活能力和汉密顿抑郁量表评分，并进行统计学分析。 结果 联合脑卒中单元组改良的巴氏指数测定日常生活能力、汉密顿抑郁量表评分均有明显改善，与普通病房治疗组比较，差异有统计学意义（P＜0.05）。 结论 联合脑卒中单元对老年脑卒中后偏瘫、吞咽障碍、抑郁患者有明显的干预作用，治疗效果优于普通病房治疗组。
