目的:探讨干扰素治疗水痘的效果。方法:将151例水痘患者随机分为3组, 治疗组Ⅰ给予干扰素100 万U/ 次,im,隔日1 次,连用3 次,治疗组Ⅱ同时予以干扰素局部外涂于水痘处, 2 次/ d;对照组病毒唑10 mg/ (kg·d),im, 一日2 次,连用5 天。除以上治疗外,3组均同时根据病情给予退热、止痒、抗炎等对症治疗。观察3组患者症状、体征变化。结果:治疗组患者症状、体征恢复所用时间明显优于对照组,同时还发现局部外涂干扰素于水痘处,其皮疹瘙痒、结痂恢复天数明显缩短。结论:干扰素治疗水痘可减轻症状,缩短病程,配合局部外用效果更佳。
Alveolar bone reconstruction simulation is an effective means for quantifying orthodontics, but currently, it is not possible to directly obtain human alveolar bone material models for simulation. This study introduces a prediction method for the equivalent shear modulus of three-dimensional random porous materials, integrating the first-order Ogden hyperelastic model to construct a computed tomography (CT) based porous hyperelastic Ogden model (CT-PHO) for human alveolar bone. Model parameters are derived by combining results from micro-CT, nanoindentation experiments, and uniaxial compression tests. Compared to previous predictive models, the CT-PHO model shows a lower root mean square error (RMSE) under all bone density conditions. Simulation results using the CT-PHO model parameters in uniaxial compression experiments demonstrate more accurate prediction of the mechanical behavior of alveolar bone under compression. Further prediction and validation with different individual human alveolar bone samples yield accurate results, confirming the generality of the CT-PHO model. The study suggests that the CT-PHO model proposed in this paper can estimate the material properties of human alveolar bone and may eventually be used for bone reconstruction simulations to guide clinical treatment.
