ABSTRACT
Objective To investigate the biomechanical properties of human calcaneus by finite element method. Methods Through CT scanning, Mimics, Geomagic and other software, the finite element model of calcaneus was established. The stress distribution and displacement tendency of calcaneus under normal standing and external force were analyzed. Results Under normal standing, the calcaneal stress was uniformly distributed and small. Under external force, the entire calcaneus stress increased significantly, and the stress on calcaneocuboid articular surface also obviously increased. Conclusions The analysis of the stress and strain distribution on calcaneus in neutral position under different loading, and the investigation on biomechanical properties of calcaneus and mechanism of calcaneal fracture will provide theoretical basis for clinical treatment of calcaneal fractures.
ABSTRACT
[Objective] To observe the clinical effect ofWen Yang Zhu Shui Formulaecombined with moxa salt packets in the treatment of malignant ascites. [Methods] 61 patients were randomly divided into an observation group(n=31) and a control group(n=30). The patients in the control group were treated with western medicine, while patients in the observation group, based on the treatment of control group, were treated with Wen Yang Zhu Shui Formulaecombined with moxa salt packets for one time a day for two weeks. The effective rates for malignant ascites and Karnofsky performance score(KPS) were compared in the two groups. [Results] The effective rate for malignant ascites in the observation group(80.64%) was higher than that in the control group (53.33%), P<0.05. The observation group showed significantly higher score of KPS than patients of the control group( P<0.05). [Conclusion]Wen Yang Zhu Shui Formulaecombined with moxa salt packets can effectively reduce the malignant ascites.
