中医学面临在继承发扬传统的基础上探求现代化转变,中医诊断的科学化、规范化、标准化、定量化和精确性等问题变得更为迫切. 提出一种基于模块化思维并以模糊熵作为判断识别依据的模糊ISODATA中医证候诊断方法,以期在系统整理临床资料、古今资料及专家经验的基础上,模拟辨证诊治过程建立中医证候诊断方法. 该方法通过对IgA肾病的辩证分型为例,识别结果与中医辩证诊断的思维大致吻合. 该方法可用于典型疾病的中医辨证诊断,对于中医专家的经验积累和知识共享具有实际应用价值. 相似文献

丘脑卒中患者认知功能损害及其临床判别 总被引:1,自引:0,他引:1
目的:探讨丘脑卒中后认知损害的特点,尝试应用回归函数方程推测和判别这种损害程度。方法:①选择2004-04/12大连市第二人民医院和大连市海港医院收治,并经CT确诊的丘脑卒中患者21例为丘脑卒中组;按1∶3匹配原则,将63例年龄与性别与丘脑卒中组匹配的非脑部疾病者入选为对照组。②丘脑卒中组住院后进行影像学和生理、生化学指标检查,对所有入组人员进行神经心理学测查其认知功能,内容包括4个纬度(智能纬度、执行功能纬度、注意机能纬度和记忆纬度)13个认知因子,以韦氏成人智力量表、韦氏记忆量表和威斯康星卡片分类实验等为测查工具。③将对照组每项认知因子均数根据其在认知中的作用不同,加或减1.64标准差为界值,以判断丘脑卒中组认知损害程度,并建立回归方程和认知损害程度表达式。结果:84例均进入结果分析。①丘脑卒中组在13个认知指标中有9个指标与对照组相比差异显著(P<0.05),4个纬度均有涉及。②建立丘脑组认知损害程度函数表达式,计算出每例认知损害程度函数值(F0)。以丘脑组每例认知损害程度函数值为应变量,以临床影响因子为自变量建立了回归方程Y=43.679-2.304*β。以Y值推测F0值。当Y<0.98,可考虑为轻度认知损害,当Y=0.98~8.15时可考虑为中度认知损害,当Y>8.15时可考虑为重度认知损害。结论:①丘脑卒中可引起广泛的认知损害。②临床可以根据影响因素建立回归方程,计算出Y值,以Y值推测F0值。 相似文献

Lhermitte-Duclos disease (LDD) is a rare benign lesion of uncertain pathogenesis characterised by distortion of the normal cerebellar laminar cytoarchitecture. We report a case of LDD thoroughly characterized by advanced magnetic resonance imaging techniques, with diffusion-weighted, perfusion-weighted and post-gadolinium sequences. Imaging showed restricted diffusion consistent with high cellularity, high degree of vascularity and preserved blood-brain barrier permeability, correlating with pathology. 相似文献

A factor produced by the oocytes induces in vitro FSH-treated cumulus and mural granulosa cells to synthesize hyaluronic acid. In the present study we examined hyaluronic acid synthesis by the two cell populations in vivo. After injection of hCG into PMSG-primed immature mice, cumulus and mural granulosa cells adjacent to the antrum synthesized a large amount of such glycosaminoglycan, while the outermost layers layers of mural granulosa cells did not. The results suggest that in vivo differences in hyaluronic acid synthesis between follicle cell subpopulations depend on a diffusion gradient of the oocyte factor. We also identified a proteoglycan species synthesized by cumulus cells which may contribute to hyaluronic acid organization in the intercellular spaces. 相似文献
