肝纤维化(Hepatic fibrosis,HF)是各种慢性肝病向肝硬化进展的必经阶段,不及时治疗将发展为肝硬化,甚至肝癌。因此,延缓或逆转HF具有重要临床意义。目前,西医尚无针对HF治疗的特效药物,故寻找新的治疗方案势在必行。TGF-β1/Smad信号通路是影响HF进展的关键通路,本文以TGF-β1/Smad信号通路为切入点,梳理、总结近年来该信号通路对炎症反应、细胞凋亡、氧化应激、细胞自噬、细胞外基质失衡等HF病理过程的调控作用,并对中药通过抑制TGF-β1/Smad信号通路治疗HF的相关研究予以综述,旨在揭示中药的作用靶点,为中医药防治HF及其现代化研究提供新的思路和策略。

针对参量声源自解调信号失真问题,根据"Berktay远场解"对其进行了理论分析,并通过实验对理论分析结果进行了验证,发现:"Berktay远场解"对自解调信号中的基频、差频可以较准确地预测,而对导致信号失真的主要因素如二次谐波、和频等的预测误差很大,不能作为失真分析的精确依据;差频不是导致参量声源自解调信号失真的主要原因,降低失真的有效途径是减小自解调信号中二次谐波、和频分量,从而使有害频率成分的数量及幅值得到有效抑制。本项研究揭示了导致参量声源自解调信号失真的主要因素及其变化规律,可为参量声源信号处理方法的研究提供有益参考。

针对阵元损坏造成超声换能器阵指向性变化的问题,该文从理论上推导了圆形活塞换能器平面阵指向性计算公式,并以之对换能器损坏后指向性变化情况进行了分析。研究表明,圆环形阵列中心装置处换能器损坏对指向性的影响远大于圆周上换能器损坏造成的影响;换能器损坏后,并不是每个定向面内的指向性都变差,但其总体指向性无疑会变差。

提出了一种基于向量传播的单粒子瞬态(SET)模拟方法。基于4值参数的模型来表征SET脉冲的形状,建立脉冲参数传播的数据库。使用查找表及经验公式来计算SET脉冲形状参数在逻辑门节点之间的传播。为了模拟SET脉冲在传播过程中的重汇聚,定义了4种重汇聚模式,并给出对应的等效脉冲计算方法。提出的基于向量传播的分析算法能够对SET脉冲的产生、传播及捕获过程进行精确分析。ISCAS'89电路的实验结果表明,该方法与Hspice仿真方法的平均误差为1.827%,计算速度提升了1 700倍。在不损失精度的前提下,该方法可对VLSI电路在通用或特定测试向量下的可靠性进行快速自动分析。
